Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram illustrating a clip light 100 clamped on a display screen 10 according to an embodiment of the invention, and fig. 2 to 3 are schematic diagrams illustrating the clip light 100 of fig. 1.
As shown in fig. 1, the clip light 100 can be clipped to the display screen 10, and the display screen 10 has a front surface 10f and a rear surface 10 b. As shown in fig. 2 and 3, the clip light 100 includes a first clip member 110, a second clip member 120 and a light emitting module 130. The first clip member 110 and the second clip member 120 are configured to abut against the front surface 10f and the rear surface 10b of the display screen 10, respectively, when the clip lamp 100 clips the edge of the display screen 10. The light emitting module 130 is connected to the first clip member 110 and includes a housing 131, a light emitting member 132, a reflecting member 133, a light transmitting member 134 and a circuit board 135. The housing 131 has a light exit 131 a. The light emitting element 132 is disposed in the housing 131 and emits light L1. The reflective member 133 is disposed in the housing 131 and configured to reflect the light L1 to illuminate the front of the front surface 10f through the light outlet 131a, the reflective member 133 has a first reflective surface 133s1 and a second reflective surface 133s2 connected to each other, the first reflective surface 133s1 is farther from the light emitting member 132 than the second reflective surface 133s2, the first reflective surface 133s1 has a plurality of first reflective points P11, each first reflective point P11 has a first radius of curvature C1 (not shown), and each first radius of curvature C1 is equal to or greater than 25 mm. Thus, the stray light L1a (the stray light L1a is illustrated in fig. 1) of the light beam L1 can be suppressed (reduced) or even eliminated.
As shown in fig. 1, the light L1 exits from the light exit 131a to form an illumination area U1, and the illumination area U1 illuminates the supporting surface 20 (e.g., a desktop) of the display screen 10. The illumination area U1 is located away from the display screen 10 and has a distinct boundary U1a, and the distinct boundary U1a forms an angle θ with the horizontal plane E1, which may be greater than 0 degrees, to prevent the light from the illumination area U1 from directly striking the user's eyes. In addition, the angle θ may be smaller than a predetermined angle, such as 10 degrees, 20 degrees or other values, so that the illumination area U1 is within a proper or desired illumination range. The illumination area U1 has a distinct boundary, referred to as a cut-off line U1b, near the display screen 10. The ratio of the brightness of the stray light L1a between the cut-off line U1b and the display panel 10 to the brightness of the illumination area U1 is, for example, less than a predetermined ratio, such as 5% or other values. The position of the cut-off line U1b can be defined according to the predetermined ratio. The brightness of the stray light L1a between the cut-off line of the illumination area of the conventional clip light and the display screen negatively affects the quality (e.g., causes reflection) of the picture displayed by the user viewing the display surface 10u of the display screen 10. In contrast to the embodiment of the present invention, due to the design of the light emitting module 130, the brightness of the stray light L1a can be suppressed (reduced) or even the stray light L1a can be eliminated, so as to prevent the stray light L1a from adversely affecting the quality of the picture displayed on the display surface 10u of the display screen 10.
As shown in fig. 3, the light emitting element 132 is disposed and electrically connected to the circuit board 135. The housing 131 includes a blocking portion 1311, which is located right under the circuit board 135 and the light emitting element 132 and can block a portion of the light L1 (e.g., an edge light of the light emitting angle range) of the light emitting element 132 to control the angle of the cut-off line U1b with respect to the display surface 10U of the display screen 10. In the present embodiment, the end surface 1311s of the blocking portion 1311 is substantially coplanar with the light emitting surface 132e of the light emitting element 132, so that the cut-off line U1b is substantially parallel to the display surface 10U of the display screen 10. However, the end surface 1311s and the light emitting surface 132e are not limited to being coplanar, as long as the light emitting surface 132e does not protrude beyond the end surface 1311s in the optical axis OA direction.
In one embodiment, the first radius of curvature C1 of each first reflection point P11 of the first reflection surface 133s1 may be between 25 mm and 200 mm (inclusive), so as to suppress (reduce) the brightness of the stray light L1a or even eliminate the stray light L1 a. As shown in fig. 3, a first included angle a11 of the tangential direction T11 of each first reflection point P11 with respect to the reference axis R1 is, for example, between 15 degrees and 60 degrees, but may also be smaller than 15 degrees or larger than 60 degrees, wherein the reference axis R1 is parallel to the optical axis OA of the light emitting element 132, so as to suppress (reduce) the brightness of the stray light L1a or even eliminate the stray light L1 a. These first reflection points P11 constitute the first reflection surfaces 133s1, and are, for example, smoothly (smoothly) distributed. In addition, the values of at least two of these first radii of curvature C1 may be the same or different.
As shown in fig. 3, the second reflecting surface 133s2 has a plurality of second reflecting points P12, each second reflecting point P12 has a second radius of curvature C2 (not shown), and each second radius of curvature C2 is equal to or greater than 30 mm, so that the light brightness of the illumination area U1 can be averaged. In one embodiment, each second radius of curvature C2 may be between 25 mm and 200 mm (inclusive). In addition, a second included angle a12 of the tangential direction T12 of each second reflection point P12 with respect to the reference axis R1 is between 10 degrees and 45 degrees, but may be smaller than 10 degrees or larger than 45 degrees, so as to average the light brightness of the illumination area U1. In addition, the optical axis OA of the light emitting element 132 can pass through the second reflecting surface 133s2, so that most or stronger light of the light emitting element 132 can be reflected by the second reflecting surface 133s2 to form the range of the illumination area U1. These second reflection points P12 constitute the second reflection surfaces 133s2, and are, for example, smoothly distributed. In addition, the values of at least two of these second radii of curvature C2 may be the same or different.
As shown in fig. 3, the reflective member 133 further includes a third reflective surface 133s3 connected to the second reflective surface 133s2, and the second reflective surface 133s2 is farther from the light emitting member 132 than the third reflective surface 133s 3. The third reflecting surface 133s3 has a plurality of third reflecting points P13. These third reflection points P13 constitute the third reflection surfaces 133s3, and are, for example, smoothly distributed. Each third reflection point P13 has a third radius of curvature C3 (not shown), each third radius of curvature C3 is equal to or greater than 1000 mm, wherein the third radius of curvature C3 is greater than the first radius of curvature C1, and the third radius of curvature C3 is greater than the second radius of curvature C2. In this way, the cut-off line U1b can be substantially parallel to the display surface 10U of the display screen 10 (as shown in FIG. 1). In addition, the numerical values of at least two of these third radii of curvature C3 may be the same or different. In one embodiment, each third radius of curvature C3 can be at most infinite, and in this design, at least a portion of the third reflective surface 133s3 is planar.
As shown in fig. 3, a third included angle a13 of the tangential direction T13 of each third reflection point P13 with respect to the reference axis R1 is between 0 degree and 20 degrees, or may be greater than 20 degrees, so that the cut-off line U1b is substantially parallel to the display surface 10U of the display screen 10, as shown in fig. 1.
As shown in fig. 3, the reflector 133 is disposed obliquely to the light exit 131 a. For example, a vertical distance DH1 (e.g., perpendicular to the light outlet 131a) of any first reflection point P11 of the first reflection surface 133s1 from the light outlet 131a is less than a vertical distance DH2 (e.g., perpendicular to the light outlet 131a) of any second reflection point P12 of the second reflection surface 133s2 from the light outlet 131a, and a vertical distance DH2 of any second reflection point P12 of the second reflection surface 133s2 from the light outlet 131a is less than a vertical distance DH3 (e.g., perpendicular to the light outlet 131a) of any third reflection point P13 of the third reflection surface 133s3 from the light outlet 131 a.
As shown in fig. 3, the first reflecting surface 133s1 and the second reflecting surface 133s2 are smoothly connected, for example. For example, a first connection point Pa is located between the first reflecting surface 133s1 and the second reflecting surface 133s2, and a tangential direction of the first connection point Pa on the first reflecting surface 133s1 is substantially coincident with a tangential direction of the first connection point Pa on the second reflecting surface 133s 2. Similarly, the second reflecting surface 133s2 and the third reflecting surface 133s3 are smoothly connected, for example. For example, a second connection point Pb is located between the second reflecting surface 133s2 and the third reflecting surface 133s3, and a tangential direction of the second connection point Pb to the second reflecting surface 133s2 substantially coincides with a tangential direction of the second connection point Pb to the third reflecting surface 133s 3.
As shown in fig. 3, the reflector 133 further includes a supporting portion 1331 and a reflecting portion 1332 connected to each other, wherein the reflecting portion 1332 has the first reflecting surface 133s1, the second reflecting surface 133s2 and the third reflecting surface 133s 3. In the present embodiment, the supporting portion 1331 and the reflecting portion 1332 are integrally formed. In another embodiment, the supporting portion 1331 and the reflecting portion 1332 may be formed separately and then combined by using a temporary or permanent combination technique to combine the supporting portion 1331 and the reflecting portion 1332. The reflective member 133 has a reflectivity of more than 90%, for example. The material of the reflective member 133 is, for example, a high-reflectivity aluminum material.
As shown in fig. 3, the relative position between the reflector 133 and the housing 131 is fixed, for example, the reflector 133 is engaged with the housing 131 to fix the relative position between the two. In one embodiment, the housing 131 includes at least one position-limiting portion 1312, and the first end 133a of the reflector 133 is located inside the position-limiting portion 1312. In the present embodiment, the position-limiting portion 1312 is, for example, a notch. In addition, the second end 133b of the reflective element 133 may abut against the blocking portion 1311 of the housing 131, or may not abut against the blocking portion 1311. Although not shown, in another embodiment, the blocking portion 1311 may have a notch, and the second end 133b of the reflective member 133 may be tightly matched with the notch of the blocking portion 1311, so as to further stabilize the relative position of the reflective member 133 and the housing 131. However, the embodiment of the invention does not limit the fixing manner of the reflection member 133 and the housing 131 as long as the relative position of the reflection member 133 and the housing 131 can be fixed.
As shown in fig. 3, the light-transmitting member 134 is disposed between the reflector 133 and the light outlet 131a, and the light-transmitting member 134 has light-transmitting property so as to allow light to pass therethrough and provide waterproof and dustproof effects. In another embodiment, the light-emitting module 130 can omit the light-transmitting member 134 if not necessary. The light-transmitting member 134 is obliquely disposed relative to the light-emitting port 131a, so that light rays with large angles in the light rays reflected by the reflecting member 133 and the light rays directly emitted by the light-emitting member 132 can be reflected or refracted by the light-incident surface 134i to remain in the housing, thereby preventing the light rays from being projected toward the display surface 10u, for example, the light-transmitting member 134 and the light-emitting port 131a have different distances, the larger of the distances is closer to the front surface 10f of the display screen 10, and the light rays with large angles hit the end surface 1311s to reduce the light rays toward the display surface 10 u. More specifically, as shown in fig. 3, the light-transmitting element 134 is disposed between the reflective element 133 and the light-emitting port 131a and has a light-incident surface 134i, an acute angle a2 is formed between the light-incident surface 134i and the light-emitting port 131a, the light-incident surface 134i has a first point P21 and a second point P22, the first point P21 is farther from the light-emitting element 132 than the second point P22, a vertical distance DH4 (e.g., perpendicular to the light-emitting port 131a) between the first point P21 and the light-emitting port 131a is smaller than a vertical distance DH5 (e.g., perpendicular to the light-emitting port 131a) between the second point P22 and the light-emitting port 131a, and the second point P22 is closer to the front surface 10f of the display panel 10 than the first point P21 (the front surface 10f is shown in fig. 1).
As shown in fig. 3, the relative position of the light-transmitting member 134 and the housing 131 is fixed, for example, the light-transmitting member 134 is engaged with the housing 131. In the embodiment, the housing 131 includes at least one engaging portion 1313, and the first end 134a of the light-transmitting element 134 is engaged with the engaging portion 1313. In an embodiment, the engaging portion 1313 is, for example, a notch, and the first end 134a of the light-transmitting member 134 can be tightly fitted with the engaging portion 1313 to fix the relative position of the light-transmitting member 134 and the housing 131. The second end 134b of the light-transmitting member 134 may abut against the barrier 1311. In another embodiment, the second end 134b of the light-transmitting member 134 may abut against the reflecting member 133, such as the bearing portion 1331 of the reflecting member 133. Although not shown, in another embodiment, the blocking portion 1311 may have a notch, and the second end 134b of the light-transmitting member 134 may be tightly fitted with the notch of the blocking portion 1311, so as to further stabilize the relative position of the light-transmitting member 134 and the housing 131. However, the embodiment of the invention does not limit the fixing manner of the light-transmitting member 134 and the housing 131 as long as the relative position of the light-transmitting member 134 and the housing 131 can be fixed. In addition, the light-transmitting member 134 is made of a light-transmitting polymer, such as a light-transmitting plastic, but not limited thereto.
As shown in fig. 3, the circuit board 135 may be disposed on the reflector 133, for example, on the supporting portion 1331 of the reflector 133. The circuit board 135 includes at least one circuit, and an anode (not shown) and a cathode (not shown) of the light emitting element 132 are electrically connected to the two circuits of the circuit board 135, respectively. The controller (not shown) of the clip light 100 can control the light emitting mode of the light emitting element 132 through the circuit of the circuit board 135.
Referring to fig. 4, a schematic diagram of a clip light 200 according to another embodiment of the invention is shown.
The clip light 200 is used to clip to the display screen 10. The clip light 200 includes a first clip member 110, a second clip member 120 and a light emitting module 230. The light emitting module 230 includes a housing 131, a light emitting member 132, a reflector 133, a light transmitting member 134, a circuit board 135 and a light absorbing layer 236. Clip lamp 200 has the same or similar features as clip lamp 100 except that light emitting module 230 of clip lamp 200 further includes a light absorbing layer 236. The light absorbing layer 236 is made of, for example, light absorbing foam or light absorbing lint.
The light absorbing layer 236 may be disposed on the surface 131s of the housing 131, the surface 131s being located on the optical path of the light L1, for example, the surface 131s facing the light emitting member 132, the light absorbing layer 236 facing the light emitting member 132 and the front surface 10f of the display screen 10, the light absorbing layer 236 being farther away from the light emitting member 132 than the reflecting member 133. Thus, the light absorbing layer 236 can absorb the light L1, and prevent the light L1 from being reflected to the display surface 10u of the display screen 10. In detail, if the light absorbing layer 236 is omitted, the reflected light L11 (indicated by a dotted line) reflected from the surface 131s is incident on the region between the illumination region U1 and the display panel 10 to form stray light. Due to the design of the light absorbing layer 236, reflected light reflected from the housing 131, and thus stray light, may be reduced or even eliminated.
In summary, the clip lamp of the embodiment of the invention is used for being clipped on a display screen and comprises a light emitting module. The reflecting piece of the light-emitting module is provided with a reflecting surface with variable curvature, and can provide at least one of the following technical effects: (1) the cut-off line of the illumination area is substantially parallel to the display surface of the display screen; (2) averaging the luminance of the illumination area; suppressing (reducing) or even eliminating stray light. In another embodiment, the light emitting module further includes a light absorbing layer, which is located in the light path of the light and can absorb the light to reduce the amount of light reflected to the display surface of the display screen.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
