Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED light sources, in particular to a linear LED light source. Background Art
[0002] LED (light emitting diode) is a solid-state semiconductor device. Existing LED light sources are generally composed of a bracket with leads, a semiconductor chip set on the bracket, and a packaging material (such as fluorescent silicone or epoxy resin) that seals the chip. The semiconductor chip contains a PN structure. When current passes through, electrons are pushed to the P region, where electrons and holes recombine and then emit energy in the form of photons to achieve lighting purposes. The wavelength of light is determined by the material that forms the PN structure.
[0003] LEDs generate heat when they emit light. Due to the limitation that linear light sources need to converge light into a straight line, the light source is enclosed in an installation cavity. Compared with other structures, heat is more concentrated and not easy to diffuse. The heat is easily concentrated together for a long time and can easily affect the service life of components such as frames and circuit boards. For this reason, the present application proposes a linear LED light source. Utility Model Content

Through the overall structural coordination design, the heat generated when the lamp beads emit light can be discharged outward through the fin group attached to the inside of the heat conduction groove. The structural design of the heat dissipation groove reduces the wall thickness of the shell and increases the surface area of the shell to further assist in heat dissipation. The ventilation grooves opened inside the fin group facilitate air circulation, thereby effectively improving the heat dissipation effect.

Light blocking frames are arranged on the inner sides of two embedded grooves, and the light blocking frames are fixed to the shell. A light guiding column is movably connected between the two light blocking frames. A focusing assembly is arranged inside the light source cavity and at the lower end of the light board. Fin groups are also symmetrically arranged on the upper end of the outer side of the shell, and the two fin groups are respectively located on the inner sides of two heat conduction grooves and fit with the shell.

[0011] As a preferred implementation of the linear LED light source provided by the utility model, a refraction seat is symmetrically arranged on the upper end between the two shading plates, and the two refraction seats are detachably connected to the two shading plates respectively.
[0012] As a preferred implementation of the linear LED light source provided by the utility model, the two ventilation grooves are both located outside the heat conduction groove.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The linear LED light source provided by the utility model, through the overall structural coordination design, enables the heat generated by the lamp bead when emitting light to be conducted outwards through the fin group attached to the inner side of the heat conduction groove, and the structural design of the heat dissipation groove reduces the shell wall thickness and increases the shell surface area to further assist heat dissipation, and the ventilation grooves opened inside the fin group are conducive to air circulation, effectively improving the heat dissipation effect;

[0031] Specifically, the focusing assembly includes a shading plate 10, and the shading plate 10 is symmetrically fixed at the lower end of the lamp board 8 and between the multiple lamp beads 9. The two shading plates 10 are convenient for avoiding light loss and guiding the light downward. A focusing plate 12 is fixed at the lower end between the two shading plates 10. In order to conveniently reflect the light guided downward to between the two shading plates 10, and then expand it laterally into a linear light beam through the focusing plate 12, a reflection plate 11 is symmetrically arranged at the lower end of the inner side of the light source cavity 2, and the two reflection plates 11 are fixed to the housing 1;
[0032] When the light is reflected by the two reflective plates 11 to between the two shading plates 10, the light is laterally expanded into a linear beam through the focusing plate 12.

The two refraction seats 13 are detachably connected to the two shading plates 10 respectively.
[0033] Furthermore, in order to facilitate the refraction of the high-brightness horizontal linear light beam emitted downward by the focusing plate 12 into a high-brightness longitudinal uniform linear light beam, an embedded groove 5 is symmetrically opened inside the shell 1 and at the lower end of the light source cavity 2, and a light blocking frame 14 is arranged on the inner side of the two embedded grooves 5.

In the process of discharging, it can be seen from the attached drawings that the two ventilation grooves 17 are both located outside the heat-conducting grooves 3, so that the part of the fin group 16 located inside the heat-conducting grooves 3 is solid and thick, so that the fin group 16 can absorb enough heat and quickly transfer it to the surrounding thinner parts to achieve heat dissipation, and the heat dissipation efficiency is high;
