Abstract
Description
Technical Field
[0001] The utility model relates to an LED lamp, in particular to a silicone integral injection-molded LED lamp. Background Art
[0002] LED injection molding (PVC, ABS, TPU, TPE) waterproof modules have been widely used in the field of advertising light box lighting. The most basic approach at present is to stick the molded lens (PMMA, PC) on the PCBA board and then place it in the injection mold for injection molding to achieve an overall waterproof effect. Because the performance of the lens, wire and external injection molding coating materials are different, there is a problem of loose bonding during injection molding, so the waterproof level of the module made in this way can only reach IP65 or IP66, and it is more difficult to improve it. In addition, the lens needs to be molded separately and fixed on the PCB circuit board in advance, which not only has high production costs, but also cumbersome production processes. Therefore, there is room for improvement. Summary of the invention
[0003] The utility model aims to provide a silicone integral injection-molded LED lamp.
[0004] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:
[0005] The utility model comprises a PCB circuit board, an LED lamp bead, an electric wire, a silicone lens and a silicone shell. The silicone lens and the silicone shell are integrally formed to cover the PCB circuit board, the LED lamp bead and one end of the electric wire.
[0006] Furthermore, the LED lamp bead is connected to the PCB circuit board, the silicone lens is located above the LED lamp bead, a groove is provided inside the silicone lens, and the LED lamp bead is located in the middle of the groove of the silicone lens.
[0007] As an improvement, an inner cavity is provided in the groove of the silicone lens, the inner cavity cover is provided above the LED lamp bead, and the silicone lens and the silicone shell are covered on the PCB circuit board and the inner cavity.
[0008] As an improvement, a conical recessed structure is provided at the outer upper end of the silicone lens.
[0009] The beneficial effects of the utility model are:
[0010] The utility model is a silicone integral injection-molded LED lamp. Compared with the prior art, the shell, lens and wire of the utility model are tightly combined with silicone, and the waterproof performance is greatly improved, which can reach the IP68 level; the silicone lens and the shell are integrally formed, which not only saves the cost of the lens mold, but also saves the process of sticking the lens, reducing the manufacturing cost; in addition, the internal cavity is preset to prevent the silicone of the silicone shell from contacting the lamp beads during injection molding and causing the color temperature to change. Therefore, there is room for improvement. BRIEF DESCRIPTION OF THE DRAWINGS
