Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

Referring to fig. 1 to 3, the utility model discloses an annular light supplement lamp capable of emitting light uniformly, which includes a light guide plate 3 and a diffusion cover 4, which are respectively annular, mounted on a light supplement lamp support 1, the diffusion cover 4 is mounted in front of the light guide plate 3, and the light supplement lamp support 1 is further matched with a light source and is located behind the light guide plate 3. In this embodiment, the light source includes and is equipped with annular array 2835 paster LED lamp pearl 21 on a light source board to reduce cost just reduces the light source and occupies the position, makes things convenient for the diversified design of product structure. As shown in fig. 2 to 4 and 8, the light supplement lamp bracket in this embodiment is annular, the light supplement lamp bracket 1 is concavely provided with an annular groove 11 for inserting and limiting the light guide sheet 3 and the diffusion cover 4, the light source is located below the annular groove 11 and emits light to the light guide sheet 3 through the bottom surface of the annular groove 11, and a plurality of through holes for passing the LED lamp beads may be formed in the bottom surface of the annular groove 11. At least one first convex column 301 is convexly arranged on the outer peripheral edge of the light guide sheet 3, at least one second convex column 401 is convexly arranged on the outer peripheral edge of the diffusion cover 4, and a limiting groove (not shown in the figure) for allowing the first convex column and the second convex column to be respectively inserted into and limited is arranged on the light supplement lamp support 1 (specifically, in the annular groove 11). Meanwhile, the outer periphery of the diffusion cover 4 may be further concavely provided with at least one clamping groove 402, and the light supplement lamp bracket 1 is provided with at least one clamping block 102 capable of being inserted into the clamping groove 402 for positioning, so that the light guide plate 3 and the diffusion cover 4 are positioned in the light supplement lamp bracket 1 for installation.

Referring to fig. 4 to 6, in the present invention, the light guide plate 3 forms an annular lens structure, the bottom surface of the light guide plate 3 forms continuous saw-tooth-shaped racks 31 along the circumferential direction, and the front surface of the light guide plate forms a continuous concave arc-shaped curved surface 32 along the circumferential direction. So that the front surface of the light guide plate 3 forms a continuous concave-convex curved surface along the circumferential direction, and an arc-shaped convex part 33 is formed between the adjacent concave-arc curved surfaces 32. Because the back of the light guide sheet 3 adopts the design of the sawtooth-shaped microstructure, light rays emitted by the light source can be refracted to two sides at a large angle through the microstructure of the sawtooth-shaped rack, the original light path is changed, the dark space between the two light sources is reduced, and the brightness of the whole circle of light spots is more uniform. The front surface of the light guide sheet 3 adopts the micro-structural design of the concave arc-shaped curved surface 32, so that light rays emitted by the lamp beads under the light guide sheet 3 can be diffused again, the light rays are softer, the brightness is uniform, and glare is reduced. Because the light guide plate 3 adopts a double-sided microstructure design, the light emitting angle can be enlarged, light can be diffused towards two sides, the dark space between two light sources is reduced, the brightness of the whole circle of light spots is more uniform, and glare is reduced.

Referring to fig. 7 to 9, in the present invention, a plurality of continuous annular ribs 41 are formed on the annular surface of the front surface of the diffuser cover 4, so that a plurality of annular ribs on the front surface of the diffuser plate 4 form a wavy line therebetween to form a wavy concave-convex curved surface. The diffusion cover 4 is made of a light-transmitting material, and diffusion powder is added into the diffusion cover 4, so that light intensity distribution is more uniform. The front surface of the diffusion cover 4 adopts an annular texture structure, so that light rays are softer, and the appearance is more attractive.

The utility model can be a light supplement lamp for a camera, and the light supplement lamp can be arranged at the back of the camera. As can be seen from fig. 10 and 11, the light supplementing lamp of the present invention has uniform light spot transition in a whole circle, has no obvious dark spot, and meets the light supplementing effect.

After the structure is adopted, the annular light supplement lamp provided by the utility model increases the light emitting angle by adopting a light guide sheet and diffusion cover scattering mode, so that the light irradiation range is larger, the spatial light intensity distribution is changed, light spots are uniformly distributed, and no yellow spots exist. Because the back of the light guide sheet is designed into the tooth-shaped microstructure, and the front of the light guide sheet is designed into the arc-shaped curved surface microstructure, light rays can be refracted to two sides at a large angle after passing through the light guide sheet, the original light path is changed, the dark space between the light sources is reduced, the interval between the two light sources can be increased, the number of the light sources can be reduced, and the light can be uniformly emitted by a whole circle of light spots. And the diffusion cover added with the diffusion powder can make the light intensity distribution more uniform, the light is softer, and the anti-dazzle effect is achieved without yellow spots. Through the combined optical design, the number and the occupied positions of the light sources can be reduced, the cost is reduced, the structural design of the product is richer, and the market competitiveness is better.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
