Description

TECHNICAL FIELD

[0001] The present application relates to a desk lamp, in particular to a honeycomb desk lamp structure. BACKGROUND

[0002] The lens of the eye-protecting desk lamp on the market does not have a grid part, and is a whole lens set. The deficiency is that the lens set is difficult to achieve the eye-protecting requirement of uniformity. In addition, the concentrated LED arrangement will cause the local light emission to be too small, which is easy to cause the problem of direct light injury to the eyes. Some honeycomb grid lens desk lamps install a light uniformity plate (non-lens) behind the plastic grid to prevent the eyes from directly viewing the light source. However, this will cause a new problem of serious ghosting. Because the light of the LED is emitted from different honeycomb reflective grids, multiple light sources are generated, and many ghosting effects are generated when the light is irradiated to the object.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] This invention relates to a honeycomb desk lamp structure, comprising a housing 100, a lens 200, and a light-emitting element 300.

[0030] like Figure 1 As shown, in this embodiment, the housing 100 may, but is not limited to, being elongated. In the illustrated direction, the downward-facing side of the housing 100 serves as the working part 110, and a grid of holes 120 is provided on this working part 110. A plurality of grid holes 120 are distributed in a honeycomb pattern on the working part 110; preferably, the grid holes 120 are hexagonal in structure. The grid holes 120 open up the upper and lower surfaces of the working part 110, thus connecting the inside and outside of the housing 100. The lens 200 is entirely made of transparent crystal material, such as transparent plastic crystal or transparent glass crystal, etc. Figure 4 As shown, the lens 200 includes a main body 210 and a convex lens 220. The main body 210 is flat, and its outer contour shape is determined by the shape of the working part 110 and the distribution of the grid holes. When the working part 110 and the grid holes 120 are distributed as follows... Figure 1If the shape shown is rectangular, then the main body 210 is a rectangular plate. If the distribution of the working part 110 and the grid holes 120 is circular, then the main body 210 is a disk. The main body 210 has a first flat end face 211 and a second flat end face 212. The first flat end face 211 is a large plane of the main body 210. The second flat end face 212 is formed by extending from the first flat end face 211 along the thickness direction of the main body 210. In space, the first flat end face 211 and the second flat end face are opposite faces, with the first flat end face 211 facing upward and the second flat end face 212 facing downward in the direction shown in the figure. The convex through-body 220 is integrally formed on the main body 210. The convex through-body 220 is recessed from the first flat end face 211 towards the second flat end face 212 and then protrudes outward from the second flat end face 212. The recessed portion of the convex lens 220 is defined as the recessed portion 221, and the end face of the convex lens 220 protruding from the second flat end face 212 is the light-transmitting surface 222. The number and distribution of the convex lenses 220 on the main body 210 are set according to the grid holes 120 on the working part 110. The lens 200 is installed inside the housing 100, with the second flat end face 212 facing downwards towards the working part 110. The convex lenses 220 correspond one-to-one with the grid holes 120, with one convex lens 220 extending into one grid hole 120. The peripheral wall of the grid hole 120 surrounds the periphery of the convex lens 220. After the lens 200 is fixed inside the housing 100, as... Figure 2 As shown, the lowest point of the convex lens 220, i.e., the end of the light-emitting surface, is level with or nearly level with the outer end face of the grid hole 120 (i.e., the lower surface of the working part 110 in the figure). Nearly level means the lowest point of the light-emitting surface can slightly exceed or slightly exceed the lower surface of the working part 110. Preferably, the height difference between the lowest point of the light-emitting surface and the lower surface of the working part 110 does not exceed 2mm. The light-emitting element 300 is installed inside the housing 100 and located above the lens 200. The light-emitting element 300 includes a plurality of first LED beads 310. The first LED beads 310 are selected from LED beads, and each first LED bead 310 corresponds one-to-one with a convex lens 220. The first LED beads 310 are arranged according to the distribution of the number of convex lenses 220. The first LED beads 310 are placed within the recess 221 of the convex lens 220. During operation, the first LED beads 310 emit light, and the light is diffused through the convex lens 220 to illuminate the outside of the housing 100. The grid aperture 120 primarily serves to partition the convex lenses 220, rather than primarily reflecting them. Light is mainly scattered directly into the external environment through the convex lenses 220. The height relationship between the convex lenses 220 and the working part 110 ensures that light, after passing through the convex lenses 220, can be dispersed to the maximum extent and evenly, without the ghosting problem of multiple light sources caused by reflections from the grid aperture 120.

[0031] In some specific embodiments of the present invention, such as Figure 2As shown, the light-transmitting surface 222 extends from the second flat end surface 212 in an arc shape, and then extends in a flat shape towards the center of the light-transmitting surface 222. The middle part of the light-transmitting surface 222 is a flat surface, which is flush or close to flush with the lower surface of the working part 110. The concave part 221 of the convex lens 220 is a spherical surface, which is a part of a complete spherical surface. The part between the concave part 221 and the light-emitting surface constitutes the solid of the convex lens 220. In the cross section, the thickness of the solid gradually decreases from the periphery of the convex lens 220 to the center. When the light passes through the solid of the convex lens 220, the part with a relatively large thickness has a large refraction effect on the light, and the part with a relatively small thickness has a small refraction effect on the light. When the light passes through the periphery of the solid, the refraction of the light to the inner wall of the grid hole 120 is reduced. When the light passes through the middle part of the solid, the light is relatively concentrated in the flat surface of the light-transmitting surface 222, and the glare and ghosting are reduced.

[0032] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The light-emitting member 300 further includes a circuit board 320, which is in a long strip shape along the extension direction of the main body 210. The first lamp beads 310 are distributed on the circuit board 320. The light-emitting member 300 is fixedly connected with the lens 200, the lower surface of the circuit board 320 is attached to the first flat end surface 211 of the lens 200, and the surface of the circuit board 320 and the concave part 221 form an enclosed space. The first lamp beads 310 are located in the enclosed space to emit light, and the grid hole 120 can avoid light leakage between the first lamp beads 310.

[0033] In some embodiments of the present application, as shown in Figure 1As shown, along the extending direction of the long side of the lens 200, a plurality of rows of convex lenses 220 are arranged on the lens 200. In the direction shown in the figure, a plurality of convex lenses 220 are arranged from left to right in each row, and the convex lenses 220 in each row are arranged from top to bottom. The number of convex lenses 220 in each row is arranged at intervals. Specifically, the first row has N convex lenses 220, the second row has N+1 convex lenses 220, the third row has N convex lenses 220, and the fourth row has N+1 convex lenses 220, and so on. The number of convex lenses 220 in every other row is the same, and the number of convex lenses 220 in adjacent rows is different. N is an integer greater than 1. Preferably, the convex lenses 220 in adjacent rows are staggered. On both sides of the row of convex lenses 220 with N convex lenses 220, a light supplement 230 is arranged. The structure of the light supplement 230 is the same as that of the convex lens 220, and the light supplement 230 protrudes from the first flat end surface 211 to the second flat end surface 212. The volume of the light supplement 230 is smaller than that of the convex lens 220. Preferably, the volume of the light supplement 230 is in the range of one-third to one-fifth of the volume of the convex lens 220. A grid hole 120 corresponding to the light supplement 230 is arranged on the working part 110, and a second lamp bead 330 corresponding to the light supplement 230 is arranged on the light emitting part 300. In use, the convex lens 220 is the main irradiation part of the light source, and the light supplement 230, which has a relatively small volume, supplements the light on the periphery of the irradiation range, thereby improving the light intensity at the peripheral positions in the irradiation range.

[0034] Further, the grid hole 120 is flared, as shown in FIG. 4. Figure 2 As shown, the upper side of the grid hole 120 is the inner side of the shell 100 / working part 110, and the lower side of the grid hole 120 is the outer side of the shell 100 / working part 110. The grid hole 120 gradually expands from the inner side to the outer side of the shell 100, i.e., the inner side wall of the grid hole 120 is inclined. The flaring of the grid hole 120 increases the irradiation range of the light after it is emitted from the convex lens 220.
