Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an optical bracket structure which is convenient to assemble. Background Art

[0002] The optical bracket structure is a component installed inside the lamp. The light emitted by the light source forms a specific light spot after passing through the optical bracket. The scale-armor reflector is an optical bracket structure with anti-glare effect. The inner surface of the scale-armor reflector is evenly distributed with multiple scale-armor units, which are reflective sheets. The chip can achieve a certain anti-glare effect after being reflected by the scale-armor units. However, the light-emitting lens of the reflector is a flat lens, such as Figure 7 As shown in the figure, its light control ability is low, and part of the light hitting the lens is reflected back to the inside of the product, causing glare on the surface of the product. At the same time, the peripheral light of the light spot is very heavy, which looks like a sunflower, very unnatural, and affects the light output effect of the lamp. Utility Model Content

[0003] The utility model aims to provide an optical bracket structure which is easy to assemble in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The utility model discloses an optical bracket structure which is easy to assemble, comprising a light source bracket and a reflective cup fixed on the light source bracket; the inner surface of the reflective cup is evenly distributed with a plurality of scale units with reflective effect; the reflective cup is provided with a lens on an end surface away from the light source bracket; the lens is attached to the reflective cup; the lens is in the shape of a convex spherical surface which bulges toward the side away from the reflective cup; the center of the convex spherical surface of the lens is arranged on the axis of the reflective cup; a plurality of clamping blocks are evenly distributed on the outer wall of the reflective cup; a plurality of lens clamping buckles which are fixed on the clamping blocks are evenly distributed on the outer wall of the lens; the edge of the lens is attached to the end surface of the reflective cup.

[0006] Furthermore, a plurality of heat dissipation grooves are provided on the end surface of the reflective cup that is in contact with the lens.

[0007] Furthermore, the light source bracket is evenly distributed with a plurality of bracket slots; the reflector cup is evenly distributed with a plurality of reflector cup buckles fixed on the bracket slots.

[0008] Furthermore, a convex ring is provided on the surface of the light source bracket facing the reflective cup; a plurality of positioning platforms are evenly distributed on the circumference of the reflective cup; an arc surface is provided on the outer surface of the positioning platform; the radius of the arc surface is equal to the inner hole radius of the convex ring; and the arc surface is pressed against the inner surface of the convex ring.

[0009] After adopting the above structure, the utility model has the following beneficial effects: when using the utility model, a small part of the light is irradiated on the scale unit of the reflective cup and then passes through the convex spherical lens. After the light reflected from the light-incoming surface of the lens is reflected by the reflective cup, the small part is concentrated on the light source, which greatly reduces the glare on the surface of the product and solves the problem of residual light weight around the light spot. The lens is fixed to the block by the lens buckle and fixed to the reflective cup, which improves the efficiency of disassembly and assembly and makes disassembly and assembly more convenient.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 8As shown, the utility model is an optical bracket structure that is easy to assemble, which includes a light source bracket 3 and a reflective cup 2 fixed on the light source bracket 3; the inner surface of the reflective cup 2 is evenly distributed with a plurality of scale units 204 with a reflective effect; the scale units 204 of the reflective cup 2 have no essential difference from the prior art, so they are not described in detail;

[0025] The reflector cup 2 is provided with a lens 1 on one end surface away from the light source bracket 3; the lens 1 is attached to the reflector cup 2; the lens 1 is in the shape of a convex spherical surface convex toward the side away from the reflector cup 2; the center of the convex spherical surface of the lens 1 is set on the axis of the reflector cup 2;

[0026] A chip positioning groove 301 is provided on the end surface of the light source bracket 3 away from the reflective cup 2; a bracket light outlet 303 is provided in the middle of the chip positioning groove 301; the light source is installed and fixed in the chip positioning groove 301, and the light enters the reflective cup 2 from the bracket light outlet 303;

[0027] A small portion of the light is irradiated on the scale unit 204 of the reflective cup 2 and then passes through the convex spherical lens 1. The light reflected from the light-incoming surface of the lens 1 is reflected by the reflective cup 2, and the small portion is concentrated on the light source, which greatly reduces the glare on the product surface and solves the problem of heavy residual light around the light spot. A plurality of blocks 202 are evenly distributed on the outer wall of the reflective cup 2; a plurality of lens buckles 101 are evenly distributed on the outer wall of the lens 1 and are fixed on the blocks 202 by buckles; the edge of the lens 1 is attached to the end face of the reflective cup 2;

[0028] The lens 1 is fixed to the clamping block 202 by the lens clamping buckle 101 and then fixed to the reflective cup 2, thereby improving the disassembly and assembly efficiency and making the disassembly and assembly more convenient.

[0029] When light hits the inner curved surface of lens 1, part of the light will be reflected back to the reflective cup, while the other part will be refracted through transparent lens 1. The reflected light will be reflected and refracted again, and finally converge at the LED light source. By designing the shape of reflective cup 2 and the arc and the angle of lens 1, the focusing effect of reflected and refracted light can be achieved, making the irradiated light more concentrated and brighter, thereby reducing the scattering and diffusion of residual light and improving the light effect.

[0030] As a preferred embodiment of the present invention, a plurality of heat dissipation grooves 201 are provided on the end surface of the reflective cup 2 that is in contact with the lens 1; the heat dissipation grooves 201 are used to dissipate heat inside the product.

[0031] As a preferred embodiment of the present invention, a plurality of bracket slots 302 are evenly distributed on the light source bracket 3; a plurality of reflector cup clips 205 are evenly distributed on the reflector cup 2 and are fixed on the bracket slots 302 by clips; the reflector cup clips 205 pass through the bracket slots 302 and are clipped and fixed on the surface of the light source bracket 3 away from the reflector cup 2, thereby realizing the connection between the light source bracket 3 and the reflector cup 2. The clip connection structure improves the efficiency of disassembly and assembly of the light source bracket 3 and the reflector cup 2.

[0032] As a preferred embodiment of the utility model, a convex ring 304 is provided on the surface of the light source bracket 3 facing the reflective cup 2; a plurality of positioning platforms 203 are evenly distributed on the circumference of the reflective cup 2; an outer surface of the positioning platform 203 is provided with an arc surface 203a; the radius of the arc surface 203a is equal to the inner hole radius of the convex ring 304; the arc surface 203a is pressed against the inner surface of the convex ring 304; each arc surface 203a is attached to the inner surface of the convex ring 304; by attaching a plurality of arc surfaces 203a to the inner surface of the convex ring 304, the reflective cup 2 and the light source bracket 3 are coaxially arranged, which can ensure the coaxiality of the light emitting chip and the reflective cup 2, and make the shape of the light emitting effect more regular.
