Referring to fig. 1, the present embodiment provides a lamp 100, where the lamp 100 includes a lamp housing 10 and a light guide plate 20. Wherein, the lampshade 10 comprises a light-transmitting part 11, and patterns are formed on the light-transmitting part 11; the light guide plate 20 includes a side surface 21 and a light exit surface 22, the light exit surface 22 is connected to the side surface 21 and the light exit surface 22 faces the light-transmitting portion 11, the side surface 21 is provided with a light source 30, the light source 30 is used for generating light, the light guide plate 20 guides the light to exit from the light exit surface 22 so as to enable the light to exit from the light-transmitting portion 11 to the outside of the lamp 100, and in addition, the light guide plate 20 and the lamp shade 10 are detachably connected together.

In the lamp 100 of the embodiment of the application, the light source 30 is disposed on the side 21 of the light guide plate 20, so that the light guide plate 20 can guide the light generated by the light source 30 to the light emitting surface 22 for emitting, and thus the light can be emitted to the outside of the lamp 100 through the light-transmitting portion 11 of the lampshade 10, at this time, since the pattern is formed on the light-transmitting portion 11, the light can display the pattern through the light-transmitting portion 11. In addition, by disposing the light source 30 on the side 21 of the light guide plate 20, the thickness of the lamp 100 is prevented from being increased by using the direct light source 30, and the size of the lamp 100 is reduced while the lamp 100 emits light uniformly.

Meanwhile, the light guide plate 20 is detachably connected to the lamp housing 10, so that the lamp housing 10 is easily maintained and replaced, and only the lamp housing 10 needs to be replaced when the display pattern needs to be replaced, thereby improving the applicability of the lamp 100.

With the development of technology, lamps and lanterns are not only a lighting or signaling device, but also can be gradually used as a type of decorative parts, such as neon LOGO lamps at the door of shops, LOGO indicator lamps with LOGO on desk lamps, automobile sign lamps and the like. In this kind of lamps and lanterns that play decorative effect, the even luminous effect of the LOGO who guarantees the pattern, the typeface on the lamps and lanterns is very important, so in order to realize even luminous effect, often arrange several light sources such as LED direct projection formula, then increase modes such as light diffuser plate or fresnel lens with light scattering cooperation translucent housing in order to realize even luminous.

It can be understood that in the above manner, a large enough distance space is required between the light source inside the lamp and the LOGO surface to be displayed on the housing of the lamp to accommodate the plurality of light sources arranged in a direct projection manner, so that the size of the lamp in the thickness direction is large, and the use scene is limited; moreover, the number of light sources required is large, for example, when using LEDs, an LED array is often required, which results in a large power and high cost of the lamp.

The lamp 100 provided in the embodiment of the present application can achieve a uniform light emitting effect and a smaller size of the lamp 100 in the thickness direction, so that the lamp 100 can be adapted to application scenes where light and thin decorative lamps are needed to be used, such as displaying car logos.

Specifically, the lampshade 10 may be used to protect components such as the light source 30 disposed inside the lamp 100, and the shape of the lampshade 10 may be regular, such as rectangular, circular, or triangular, or irregular.

The lamp cover 10 may be made of plastic, or the lamp cover 10 may be formed by injection molding, which enables the lamp cover 10 to have low manufacturing cost and light weight, and compared to the lamp cover 10 made of tempered glass or organic glass, i.e., acrylic material, the lamp cover 10 made of plastic has stronger impact resistance.

Of course, the lampshade 10 may also be made of toughened glass, organic glass, etc., and the application does not specifically limit the material and shape of the lampshade 10.

The lamp housing 10 is formed with a pattern or a character for displaying a brand identity of a product, etc. The part of the lampshade 10 where the pattern is formed is the light-transmitting part 11, that is, the light-transmitting part 11 is overlapped with the pattern on the lampshade 10, so that when light is emitted out of the lampshade 10 through the light-transmitting part 11, the pattern part of the lampshade 10 can play a role of luminescence to display the pattern.

The light guide plate 20 may be used to convert a linear light source into a surface light source and guide the light to be emitted, and the light guide plate 20 may be used in combination with the lamp housing 10 to achieve a lighting effect with high uniformity and high brightness.

The light guide plate 20 may have a regular shape such as a rectangle, a circle, or a triangle, or may have an irregular shape, and it is understood that the light guide plate 20 may be cut into a desired size as long as the light guide plate 20 guides the emitted light to make the light-transmitting portion 11 of the lamp cover 10 emit light uniformly.

The light guide plate 20 may be made of a transparent material with a high refractive index, such as organic glass or polycarbonate, to provide a high refractive index and a high total light transmittance.

The light guide plate 20 includes a side surface 21 and a light emitting surface 22, the light emitting surface 22 is connected to the side surface 21, and the side surface 21 is provided with a light source 30. The light source 30 may be a light emitting source such as an LED for generating light, and the number of the light sources 30 may be plural, for example, the light sources 30 are disposed on both the left and right side surfaces 21 of the light guide plate 20. Since the light guide plate 20 is designed to be incident light from the side 21, that is, the light source 30 is disposed at the side 21 of the light guide plate 20, the thickness of the light guide plate 20 can be reduced.

The light exit surface 22 of the light guide plate 20 faces the light-transmitting portion 11, so that the light guide plate 20 can emit the light generated by the light source 30 on the side surface 21 through the light exit surface 22, so that the light is emitted to the light-transmitting portion 11 and then emitted to the outside of the lamp 100, and thus the pattern on the light-transmitting portion 11 has a light-emitting effect.

The light guide plate 20 can be detachably connected to the lamp housing 10, or the light guide plate 20 is not fixedly connected to the lamp housing 10 by glue, tape, or the like. Thus, the lampshade 10 can be easily detached from the lamp 100 for maintenance or replacement, so that when the pattern needs to be replaced for display, the lampshade 10 only needs to be detached for replacement, thereby improving the applicability of the lamp 100.

Referring to fig. 1, in some embodiments, the light-transmitting portion 11 may enable light to be diffusely reflected on the light-transmitting portion 11 and to exit to the outside of the lamp 100.

Thus, the light rays are diffusely reflected on the light-transmitting portion 11 and emitted out of the lamp 100, so that the light-emitting effect of the light-transmitting portion 11 is more uniform, and the light-emitting brightness is higher, thereby bringing a better lighting effect to the pattern on the light-transmitting portion 11.

Specifically, the light-transmitting portion 11 on which the pattern is formed on the lamp housing 10 may be made of a transparent material, so that the light transmittance of the light-transmitting portion 11 is higher; also, in order to ensure that the pattern can be illuminated more uniformly, the light-transmitting portion 11 also needs to have a relatively high light diffusivity. Therefore, the lamp cover 10 may be made of a polycarbonate plate (PC plate), and a diffusing agent is often added when the lamp cover 10 is manufactured and then formed by a process such as injection molding or extrusion.

Thus, the light guided to the light-emitting surface 22 by the light guide plate 20 can diffuse the partially non-uniform light at the light-transmitting portion 11 of the lamp shade 10, i.e., diffuse reflection is performed to ensure that the light emitted to the outside of the lamp 100 is more uniform, so that the whole light-transmitting portion 11 forms a uniform light-emitting surface, and the visual effect when the pattern is lighted is better.

Referring to fig. 1, in some embodiments, the lamp housing 10 may include a non-light-transmissive portion 12 surrounding a light-transmissive portion 11.

In this way, by providing the non-light-transmitting portion 12 surrounding the light-transmitting portion 11 on the lamp housing 10, the light guided to the light-emitting surface 22 through the light guide plate 20 is blocked by the non-light-transmitting portion 12 and is only transmitted from the light-transmitting portion 11 in accordance with the pattern, so that the effect of lighting only the pattern on the light-transmitting portion 11 is achieved.

Specifically, in order to illuminate only the light-transmitting portion 11 of the lamp cover 10 to achieve the effect of displaying the design, the lamp cover 10 further includes a non-light-transmitting portion 12 surrounding the light-transmitting portion 11. The non-light-transmitting portion 12 may be made of a non-light-transmitting material, or the non-light-transmitting portion 12 may be ground, painted, or pasted to shield the light rays guided to the lampshade 10 through the light guide plate 20 for diffuse reflection from the non-light-transmitting portion 12 and only transmit the light rays through the light-transmitting portion 11 in accordance with the pattern, so as to achieve the effect of lighting only the pattern on the light-transmitting portion 11.

Referring to fig. 2, in some embodiments, the light guide plate 20 may include a bottom surface 23, wherein the bottom surface 23 is opposite to the light emitting surface 22, dots 24 may be disposed on the bottom surface 23, and the dots 24 may be used for guiding light to the light emitting surface 22.

In this way, the dots 24 are disposed on the bottom surface 23 of the light guide plate 20, so that the dots 24 can be used as light guide points, and at the positions of the dots 24, the light generated by the light source 30 is emitted to the light emitting surface 22 of the light guide plate 20 through the action of the light guide points without being regularly totally reflected, so that the light can be guided to the light emitting surface 22 disposed toward the light transmission portion 11, and the light can be emitted from the light transmission portion 11 to the outside of the lamp 100.

Specifically, the light guide plate 20 can convert the linear light source into the surface light source by an optical action, and the light guide plate 20 in this application is a side light type, that is, the light source 30 is installed on the side surface 21 of the light guide plate 20. The light guide plate 20 is made of acrylic having high transmittance, and has a smooth and flat surface, and most of the light incident from the internal light source 30 is regularly and totally reflected on the flat surface thereof, and is not emitted to the outside of the light guide plate 20.

Then, in order to guide the light to the light-emitting surface 22 for emitting, so that the light is emitted from the light-transmitting portion 11 of the lampshade 10 to the outside of the lamp 100, a bottom surface 23 of the light guide plate 20 opposite to the light-emitting surface 22 is printed with white dots 24. As shown in fig. 2, at the position where the dots 24 are printed on the light guide plate 20, the light is not regularly reflected, but is emitted to the light emitting surface 22 of the light guide plate 20, i.e. the dots 24 can change the direction of the light entering the light guide plate 20 from the side. In this way, controlling the density of the dots 24 at each position of the light guide plate 20 can control how much light is emitted from the light guide plate 20 at the position, thereby achieving uniform illumination of the light-transmitting portion 11.

The dots 24 on the light guide plate 20 may be formed by UV screen printing, laser engraving, or V-shaped cross grid engraving. When the light generated by the light source 30 strikes each dot 24, i.e., the light guide point, the reflected light is diffused at each angle, and then the reflected light is emitted from the light emitting surface 22 of the light guide plate 20 by destroying the reflection condition, so that the light guide plate 20 can uniformly emit light by engraving, carving, dense or different sizes of the dots 24, thereby realizing uniform illumination of the light transmission part 11.

Referring to fig. 2, in some embodiments, the number of dots 24 may be multiple, and the area of the dots 24 may increase in a direction away from the light source 30.

In this way, by disposing a plurality of dots 24 and disposing the dots 24 such that the area of the dots 24 increases along the direction away from the light source 30, the position of the dots 24 in the direction away from the light source 30 is farther away from the light source 30, but the area of the dots 24 increases, so that the light is easier to be emitted out to the light-emitting surface 22 through the dots 24, and the uniformity of the light emitted from the light guide plate 20 can be increased.

Specifically, since the light source 30 is disposed on the side 21 of the light guide plate 20 in order to reduce the thickness of the light guide plate 20 and thus reduce the size of the luminaire 100 in the thickness direction, the area of the light incident side dots 24 can be designed to be smaller, and the area of the dots 24 gradually increases as the positions of the dots 24 are gradually away from the light source 30, considering that the dots 24 are designed to prevent the light incident side, i.e., both sides near the position of the light source 30, from leading out too high light intensity through the dots 24 beyond the light exit surface 22, and the light exit intensity from the central position of the light guide plate 20 far away from the light source 30 is too low.

In this way, at the central position of the light guide plate 20 far away from the light source 30, due to the increase of the area of the dots 24, the light is easier to be emitted to the light emitting surface 22 through the dots 24, so that the distribution of the surface light source 30 converted by the light guide plate 20 can be improved, the light emitting uniformity of the light guide plate 20 can be improved, the light guide plate 20 can uniformly emit light, and the light transmitting portion 11 can be uniformly illuminated.

Referring to fig. 2, in some embodiments, the number of the dots 24 may be multiple, and the arrangement density of the multiple dots 24 may increase in a direction away from the light source 30.

Thus, by arranging the plurality of dots 24 and setting the arrangement of the plurality of dots 24 to be the arrangement density of the plurality of dots 24 along the direction away from the light source 30 to be increased, the dots 24 are arranged more densely at the position away from the light source 30, although the position is farther away from the light source 30, so that the light can be emitted to the light emitting surface 22 through the dots 24 at the position more easily, and the light emitting uniformity of the light guide plate 20 can be increased.

Specifically, the arrangement of the plurality of dots 24 may be such that the area of the dots 24 increases in a direction away from the light source 30, or the arrangement density of the plurality of dots 24 may increase in a direction away from the light source 30. That is, the distribution of the dots 24 follows a sparse-dense arrangement from small to large.

It can be easily understood that, at the central position of the light guide plate 20 far away from the light source 30, since the dots 24 are more densely arranged, the light can be more easily emitted to the light emitting surface 22 through the dots 24, so that the distribution of the surface light source 30 converted by the light guide plate 20 can be improved, the light emitting uniformity of the light guide plate 20 can be improved, the light guide plate 20 can uniformly emit light, and the light transmitting portion 11 can be uniformly illuminated.

Referring to fig. 2, in some embodiments, the thickness D of the light guide plate 20 may be in a range of 2mm to 4 mm.

Thus, the light source 30 is disposed on the side 21 of the light guide plate 20, so that the thickness of the light guide plate 20 can be reduced, the thickness range D of the light guide plate 20 is controlled to be 2mm-4mm, the size of the lamp 100 in the thickness direction can be effectively reduced, and the lamp 100 can adapt to more large application scenes.

Specifically, as the backlight module is gradually thinned and in the application scenario of the small LOGO-type decorative lamp 100, in order to reduce the size of the lamp 100 in the thickness direction, the light source 30 may be disposed on the side surface 21 of the light guide plate 20 to control the thickness range D of the light guide plate 20 to be between 2mm and 4mm, and both the thinness of the light guide plate 20 and the intensity of the light guided out by the light guide plate 20 may be considered.

It can be understood that the output light intensity of the light guide plate 20 with the thickness less than 2mm is low, and the difficulty of printing the dots 24 by adopting the silk-screen printing process is high when the dots 24 are printed on the bottom surface 23 of the light guide plate 20; if the thickness of the light guide plate 20 is greater than 4mm, the dimension of the lamp 100 in the thickness direction is increased, which is not favorable for the light and thin of the lamp 100.

The thickness of the light guide plate 20 can be selected to be about 3mm to consider the lightness and thinness of the light guide plate 20 and the intensity of the light guided out by the light guide plate 20, and a large space can be saved in the thickness direction of the lamp 100.

Referring to fig. 2, in some embodiments, the light source 30 may be an LED light source or a COB light source. Thus, the brightness and softness of the light generated by the light source 30 can be improved.

Specifically, the LED light source is a light emitting diode light source, which has the advantages of small size, long service life, high efficiency, and the like, and the low cost of the LED light source also achieves a good light emitting effect, thereby reducing the production cost of the lamp 100.

Preferably, the light source 30 may also be a COB light source, which may be in a long strip shape, also called a high power integrated surface light source. COB light source is the integrated area source technique of high light efficiency with the direct mirror surface metal substrate of pasting the LED chip on high reflectance, compares in LED light source, has that luminance is higher, light is softer and the thermal diffusivity is better, the advantage that the thermal resistance is littleer. The COB light source can design light source light-emitting area and overall dimension according to product overall structure, consequently can effectively promote the design space of lamps and lanterns 100.

Referring to fig. 1, in some embodiments, the lamp 100 may further include a housing 40, and both the lamp cover 10 and the light guide plate 20 may be mounted on the housing 40.

Thus, the lampshade 10 and the light guide plate 20 are mounted on the housing 40, so that the lampshade 10 and the housing 40 jointly protect the internal parts of the lamp 100, and the lampshade 10, the light guide plate 20 and the housing 40 form a whole with a compact structure, so that the mounting area of the lamp 100 is smaller, and the lamp 100 is lighter.

Specifically, the housing 40 may have a regular shape such as a rectangle, a circle, or a triangle, and of course, the housing 40 may have an irregular shape. The housing 40 may be shaped to fit the light guide plate 20 and the lamp housing 10 such that the lamp housing 10 and the light guide plate 20 can be mounted on the housing 40.

The housing 40 may be made of resin, or the housing 40 may be formed by an injection molding process, so that the manufacturing process of the housing 40 is simple and the weight of the housing 40 is lighter, but the housing 40 may also be made of metal material such as alloy, so as to ensure that the housing 40 has certain rigidity and is more durable.

The housing 40 may have a certain thickness, and the housing 40 may have a hollow structure, and the hollow portion may form an accommodating space 41 for installing the light guide plate 20 within a certain thickness range D in the accommodating space 41. The light guide plate 20 may be adhered to the housing 40 to be received in the receiving space 41, but the light guide plate 20 may be detachably mounted to the housing 40.

After the light guide plate 20 is accommodated in the accommodating space 41, the lamp shade 10 is fixedly connected with the housing 40, wherein the connection mode between the light guide plate and the housing may be glue adhesion, or detachable connection through fasteners such as screws, or a fastening structure for fastening the light guide plate and the housing.

The embodiments of the present application do not inherently limit the specific arrangement of the lamp housing 10 and the light guide plate 20 on the housing 40. As long as the lamp housing 10, the light guide plate 20 and the housing 40 are integrated into a compact structure.

Thus, the lampshade 10 and the housing 40 jointly protect the internal parts of the lamp 100, and the lampshade 10, the light guide plate 20 and the housing 40 form a compact integral body, so that the installation area of the lamp 100 is smaller, and the lamp 100 is lighter.

Referring to fig. 1, in some embodiments, the lamp 100 may further include an adhesive 50, and the light guide plate 20 and the housing 40 may be fixed by the adhesive 50.

Thus, the light guide plate 20 and the housing 40 are bonded and fixed by the adhesive 50, so that the fixing manner of the light guide plate 20 and the housing 40 is simple and easy, the cost of the lamp 100 is saved, and the installation space of the internal parts of the lamp 100 is saved.

Specifically, the adhesive 50 may be a double-sided adhesive, so that the light guide plate 20 may be accommodated in the accommodating space 41 and be adhesively connected to the housing 40. The adhesive 50 may be a double-sided adhesive with non-woven fabric base material, and has good adhesiveness and processability, and is suitable for assembling electronic device parts and bonding display screen lenses. Of course, other materials, such as the adhesive 50 without a base material such as double-sided tape, are also possible.

Compared with the fixation by fasteners such as screws, the assembly precision of the adhesive 50 is better, the assembly structure and the gap can be reduced, and the overall structure of the lamp 100 is more compact. The adhesive 50 is used for bonding and fixing the connection, so that the assembly structure is reduced, the fixing mode is simple and convenient, the cost is saved, and the installation space of the internal parts of the lamp 100 is also saved.

The assembly process and principle of the lamp 100 provided in the embodiment of the present application are as follows:

the lamp 100 includes a lamp housing 10, a light guide plate 20, an adhesive 50, and a housing 40, wherein the light guide plate 20 and the housing 40 can be adhered together by the adhesive 50 on both sides, so that the light guide plate 20 can be accommodated in the accommodating space 41; then, the lampshade 10 and the housing 40 are detachably connected together by fasteners such as screws, so that the lamp 100 is convenient to repair and maintain, and the lamp 100 is assembled.

The light guide plate 20 includes a side surface 21 and a light emitting surface 22, the side surface 21 is provided with an LED light source or a COB area light source, and since the light guide plate 20 is designed to be side-incident light, the thickness of the light guide plate 20 can be made smaller, for example, 3 mm. The number of the light sources 30 may be multiple, so as to provide a comprehensive side incident light, the light guide plate 20 may convert the linear light source into a surface light source, the bottom surface 23 of the light guide plate 20 is further printed with a plurality of dots 24, the arrangement of the dots 24 is a certain rule, and the dots 24 may be light guide points to guide the side incident light to the light emitting surface 22.

Because the area and the arrangement density of the dots 24 on the light guide plate 20 are controlled, the amount of light guided out from the light guide plate 20 at the positions of the dots 24 can be controlled, and the dots 24 are arranged regularly, so that the light guided to the light-emitting surface 22 by the dots 24 and emitted from the light-transmitting portion 11 to the outside of the lamp 100 is uniform and consistent, and the lighting effect of high uniformity and high brightness of the light-transmitting portion 11 can be realized. In particular, since the light transmitting portion 11 has high diffusibility, the light emitted to the light transmitting portion 11 can be diffusely reflected on the light transmitting portion 11, which assists in achieving a uniform lighting effect. And the light-transmitting part 11 on the lampshade 10 is consistent with the pattern, so that the pattern can be displayed, and a good display effect is achieved.
