The lamp in the embodiment of the utility model will now be described.

Referring to fig. 1 to 3, the lamp includes a housing 110, a reflector 200, a circuit board 300, and an optical assembly 500.

One side of the housing 110 has a light emitting portion 111. The light emitting portion 111 may be a light emitting hole or a flat plate made of a light transmitting material, so that light inside the housing 110 is emitted from the light emitting portion 111. The housing 110 has a length direction X, a width direction Y, and a thickness direction.

Alternatively, the lamp is a pendant lamp, and a hanging mounting member 140 is mounted on a side surface of the housing 110 away from the light emitting portion 111. The height direction Z of the housing 110 is arranged in correspondence with the vertical direction. The top of the lamp is mounted on a roof or the like by a hanging mount 140, and the bottom of the lamp emits light by a light emitting portion 111. At this time, the large light emitting angle of the lamp means that more light is emitted from the lamp along the horizontal direction or near the horizontal direction, and the light is easy to enter eyes of a user, so that glare is serious. In other words, the light fixture irradiates an object such as a desk, a book, or a decoration vertically, and the larger the light emitting angle of the light fixture is, the more light rays are emitted along the direction parallel or approximately parallel to the light emitting portion 111, which are easy to enter eyes of a user, and glare is generated.

Alternatively, the housing 110 is elongated, the elongated direction of the housing 110 is the length direction X thereof, and the length dimension of the housing 110 is much larger than the width dimension and the height dimension thereof, so that it is difficult to increase the light emitting area and reduce the glare ratio by changing the width of the light emitting portion 111. At this time, the lamp is a bar lamp. The number of the hanging installation pieces 140 can be more than two, and the hanging installation pieces 140 are distributed at intervals along the length direction X of the shell 110, so that the lamp is stressed uniformly, and the hanging is stable. For example, with reference to fig. 1, the number of suspension mounts 140 is two, and the two suspension mounts 140 are spaced apart along the length direction X of the housing 110.

Referring to fig. 3, the reflector 200 is installed in the housing 110, and the reflector 200 is located at one side of the light emitting portion 111. The circuit board 300 is mounted in the housing 110, the circuit board 300 is electrically connected with a plurality of LED chips 400, the LED chips 400 emit light toward the reflector 200, and the light emitted by the LED chips 400 is prevented from being directly emitted to the outside of the housing 110. Since the LED chip 400 is a point light source, if light emitted from the LED chip 400 is not reflected but directly irradiated to the outside of the case 110, a plurality of point light sources are present on the irradiated object, generating multiple shadows. In addition, the LED chip 400 is directly projected to the outside of the case 110 without being reflected and mixed, and has high local brightness, is liable to cause glare, and is harmful to blue light.

Specifically, the LED chip 400 is located between the light-emitting portion 111 and the reflector 200, and the LED chip 400 emits light toward the reflector 200, so that the light can be incident on the reflector 200 without blocking, the light reflected by the reflector 200 can exit to the light-emitting portion 111 opposite to the reflector 200, and the light path is smooth.

In the illustrated embodiment, the reflector 200 is disposed around the circuit board 300, and one side of the reflector 200 near the light emitting portion 111 is open, and the reflector 200 covers the circuit board 300 in a substantially semicircular shape. The light emitted from the LED chip 400 can be directly emitted to the reflector 200 and reflected to the light emitting portion 111 via the reflector 200 without light loss.

Referring to fig. 3 and 4, when the lamp is a bar lamp, the circuit board 300 is elongated, and the length direction of the circuit board 300 coincides with the length direction X of the housing 110. The plurality of LED chips 400 are spaced apart along the length direction X of the housing 110. In order to avoid the overlong circuit board 300, the circuit board 300 may be divided into more than two sections, and the more than two sections of circuit boards 300 are distributed at intervals along the length direction X, so as to reduce the production difficulty and the assembly difficulty. Similarly, the reflector 200 is elongated, and the length direction of the reflector 200 coincides with the length direction X of the housing 110, and the reflector 200 is divided into two or more segments.

Specifically, referring to fig. 4, the lamp further includes a fixing frame 120, the fixing frame 120 is mounted inside the housing 110, and the circuit board 300 is mounted on the fixing frame 120. The circuit board 300 can be assembled on the fixing frame 120, the fixing frame 120 is assembled on the shell 110, the circuit board 300 is prevented from being directly fixed in a narrow space of the shell 110, and the assembly difficulty of the circuit board 300 is simplified. Alternatively, the fixing frame 120 is located at the middle of the circuit board 300 along the length direction X, so that the fixing frame 120 has a smaller volume and less influence on the light path. For example, the circuit board 300 is two-section, wherein one section of the circuit board 300 is mounted on one end of the fixing frame 120, and the other section of the circuit board 300 is mounted on the other end of the fixing frame 120. Further, the lamp further includes a first supporting frame 130, the first supporting frame 130 is mounted on the housing 110, and the first supporting frame 130 and the fixing frame 120 are distributed at intervals along the length direction X, so as to avoid too much suspension of the circuit board 300. In the illustrated embodiment, the number of first support frames 130 is the same as and corresponds to the number of segments of the circuit board 300. The lamp may further include a second support 160, the circuit board 300 is mounted on the second support 160, and the second support 160 is mounted on the fixing frame 120. The second supporting frame 160 is a rigid frame, and prevents the circuit board 300 from bending and deforming. The second supporting frame 160 has a clamping groove for fixing the circuit board 300, so that holes on the circuit board 300 are avoided.

Specifically, referring to fig. 3 and 4, the lamp further includes a driving assembly 610, the driving assembly 610 is mounted in the housing 110, and the driving assembly 610 is electrically connected to the circuit board 300. The drive assembly 610 is used to provide power or transmit data to the circuit board 300. Alternatively, the driving assembly 610 and the circuit board 300 are distributed along the height direction Z of the housing 110. The side of the housing 110 away from the light emitting portion 111 has an opening, so that the driving assembly 610 can pass through the opening and the external power source. The light fixture may further include a cover plate 150 removably mounted at the aperture.

In this embodiment, the optical component 500 covers the light emitting portion 111, the optical component 500 totally reflects and/or refracts at least part of the light reflected by the reflector 200, and the angle range of the outgoing light of the optical component 500 is smaller than the angle range of the incoming light of the optical component 500.

Referring to fig. 5, the light emitted from the led chip 400 is reflected by the reflector 200 and refracted by the optical component 500 and then emitted outwards, so that the light is uniformly mixed in the housing 110, the illumination brightness is uniform, the light path distance is increased, the local brightness is prevented from being too high, the maximum brightness is effectively reduced, the blue light hazard is eliminated, and the blue light test can be passed. Meanwhile, the optical component 500 totally reflects and/or refracts the light with a large angle, the angle range b of the emergent light of the optical component 500 is smaller than the angle range a of the incident light of the optical component 500, the light emitting angle of the lamp is reduced, and the glare rate is reduced.

Referring to fig. 5, an angle range a of incident light of the optical assembly 500 refers to a maximum included angle formed on a cross section perpendicular to the length direction X of the housing 110 when light emitted from the LED chip 400 is reflected by the reflector 200 and then enters the optical assembly 500, and an angle range b of emergent light of the optical assembly 500 refers to a maximum included angle formed on a cross section perpendicular to the length direction X of the housing 110 when light is emitted outwards through the optical assembly 500.

In this embodiment, the optical component 500 is designed such that the angle range b of the outgoing light is smaller than the angle range a of the incoming light. There are many specific configurations of the optical assembly 500. For example, the optical module 500 is an optical lens having a condensing effect such as a convex lens or a prism, and the emission angle is reduced. The material of the optical component 500 may be PC material, acryl material or glass material, which is not limited herein.

In one embodiment, referring to fig. 6 and 7, the optical assembly 500 includes a first lens 510, and the light incident side of the first lens 510 is a first incident plane 511, and since the first lens 510 covers the light emitting portion 111, the first incident plane 511 is parallel to the light emitting portion 111. The light emitting side of the first lens 510 has a plurality of exit inclined planes 512 distributed along the width direction Y of the housing 110, and a first included angle 513 is formed between an end of the exit inclined plane 512 near the edge of the housing 110 and the first incident plane 511. The light L1 exits from the middle of the housing 110 toward the edge of the housing 110, and because the first included angle 513 is an acute angle, the light L1 falls on the exit inclined plane 512 and is located on one side of the edge of the housing 110, which is close to the normal direction of the exit inclined plane 512, so that after the light L1 is refracted, the refracted light L1 is located on one side of the edge of the housing 110, which is far away from the normal direction of the exit inclined plane 512, the angle of the light L1 is reduced, the exit angle of the lamp is reduced, and the glare ratio is reduced.

Specifically, in conjunction with fig. 6 and 7, in the width direction Y of the housing 110, the first included angle 513 gradually increases in a direction from the middle of the housing 110 to the edge of the housing 110. Since the angle of the light ray closer to the edge of the housing 110 is larger, the first included angle 513 is designed to be larger, so that the light ray L1 falls on one side of the normal direction of the exit slope 512, which is close to the edge of the housing 110, and the refracted light ray L1 is located on one side of the normal direction of the exit slope 512, which is far away from the edge of the housing 110, and the first included angle 513 is designed to be larger, so that the light emitting angle of the lamp can be reduced in a targeted manner.

Optionally, the first lens 510 is a fresnel lens. One side of the Fresnel lens is a smooth surface, which is used as the first incident plane 511, and the other side of the Fresnel lens is provided with a plurality of saw-tooth structures, and the saw-tooth structures can be used as the emergent inclined surfaces 512. The Fresnel lens has the same converging function as the convex lens, reduces the light emitting angle, is thinner than the convex lens, is favorable for reducing the attenuation of light and improves the light efficiency.

In one embodiment, referring to fig. 8, the optical assembly 500 includes a second lens 520, the light-emitting side of the second lens 520 has a plurality of reflective slopes 521 distributed along the width direction Y of the housing 110, the reflective slopes 521 have a total reflection critical angle, and the reflective slopes 521 are used for total reflection of light rays with an incident angle greater than or equal to the total reflection critical angle. The second lens 520 can totally reflect the light L2 with a large angle, and avoid outgoing outwards, so that the light emitting angle of the lamp is limited, and the glare rate is reduced.

Specifically, the light incident side of the second lens 520 has a second incident plane, and the reflective inclined plane 521 includes a first reflective inclined plane 5211 and a second reflective inclined plane 5212, and the first reflective inclined plane 5211 and the second reflective inclined plane 5212 gradually approach in a direction away from the second incident plane. The first reflecting inclined plane 5211 and the second reflecting inclined plane 5212 are oppositely arranged, and are used for carrying out total reflection on the large-angle light rays on the left side and the right side respectively, controlling the light emitting angles of the light rays on the two sides, further limiting the light emitting angle of the lamp and being beneficial to reducing the glare ratio. Of course, the second lens 520 may include only the first reflecting inclined plane 5211 or the second reflecting inclined plane 5212, that is, only the left or right large-angle light is totally reflected, which can reduce the light emitting angle of one side and reduce the glare ratio.

Alternatively, the first reflecting inclined plane 5211 and the second reflecting inclined plane 5212 are connected to form a triangular prism with the second plane of incidence. It is understood that in other embodiments, the first reflective bevel 5211 and the second reflective bevel 5212 are connected by other bevels or flats, forming a four-sided prism or a five-sided prism or the like.

In some embodiments, referring to fig. 3, the led chip 400 includes a first bead group 410, a second bead group 420, and a third bead group 430 sequentially disposed along a width direction Y of the housing 110, and the first bead group 410 and the third bead group 430 are located between the second bead group 420 and the light emitting portion 111. Thus, the first lamp bead group 410, the second lamp bead group 420 and the third lamp bead group 430 are distributed along the width direction Y of the housing 110, and are distributed at intervals along the direction close to the light emitting portion 111, which is beneficial to the uniformity of the internal light of the lamp, so that the light emitted by the reflector 200 and the optical assembly 500 is also uniform, and multiple shadows are avoided.

Specifically, the first, second and third bead groups 410, 420 and 430 are electrically connected to the circuit board 300 independently of each other. The user can flexibly select and turn on the light sources of any combination of the first, second and third bead groups 410, 420 and 430 according to the lighting requirements.

Wherein, the lamp bead group of difference is luminous, and the luminous angle of lamps and lanterns is different. For example, the reflector 200 is a parabolic reflector, that is, the cross section of the reflector 200 in the direction X perpendicular to the length direction of the housing 110 is parabolic, the second lamp bead group 420 is located at the focal point of the parabolic reflector, and when the second lamp bead group 420 is individually lighted, the angle range of the light reflected by the reflector 200 is minimum, that is, the lighting angle of the lamp is minimum. And when the first and third bead groups 410 and 430 are individually lighted, respectively, the lighting angle of the lamp is maximized. When the first bead set 410, the second bead set 420 and the third bead set 430 are all lighted, the lighting angle of the lamp is between the two.

Optionally, the circuit board 300 includes a first circuit board 310, a second circuit board 320, and a third circuit board 330. The first lamp bead group 410 is mounted on the first circuit board 310, the second lamp bead group 420 is mounted on the second circuit board 320, and the third lamp bead group 430 is mounted on the third circuit board 330.

Optionally, the lamp further includes a gesture sensor 620, where the gesture sensor 620 is electrically connected to the circuit board 300, and the gesture sensor 620 is used for controlling the working states of the first lamp bead group 410, the second lamp bead group 420, and the third lamp bead group 430. The user can switch first lamp pearl group 410, second lamp pearl group 420 and third lamp pearl group 430 through the gesture intelligently, and the operation is comparatively convenient.

Specifically, the user sequentially switches different working states of the lamp through the same gestures. For example, the user swings the hand once, the second lamp bead group 420 emits light alone, swings the hand once again, the first lamp bead group 410 emits light alone, swings the hand once again, the third lamp bead group 430 emits light alone, swings the hand once again, and the first lamp bead group 410, the second lamp bead group 420 and the third lamp bead group 430 all emit light to circulate in sequence. Of course, the user may also control different combinations of lighting through different gestures.
