Embodiment Construction

[0014] The ultraviolet LED lamp bead of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the ultraviolet LED lamp bead includes a glass lamp body 1, and a chip 2 is arranged inside the lamp body 1, and the chip 2 is a structure for emitting light, and a pair of pins are electrically connected to the chip 2 3. The pin 3 is connected to the circuit board, so that the power supply can supply power to the chip 2 through the pin 3, so that the chip 2 can emit light. There is also a transparent lamp body 1 located directly above the chip 2. Silica gel pad 4, phosphor powder 5 is arranged between the silica gel pad 4 and the chip 2, the phosphor powder 5 is bonded on the chip 2, and the lamp body 1 is also provided with a cooling post 6, and the cooling post 6 That is, a cylinder made of heat-conducting material, the lamp body 1 is provided with a groove 7 for accommodating the heat dissipation column 6, ...

Abstract

The invention provides an ultraviolet LED lamp bead which adopts the structure that a transparent silicone pad is arranged at a position right above a chip in a lamp body; fluorescent powder is arranged between the silicone pad and the chip; a heat dissipation column is also arranged on the lamp body; the chip is in contact with the heat dissipation column. Through the arrangement of the silicone pad and the fluorescent powder, the problems of ageing and yellowing of the lamp body can be effectively avoided, the illumination performance of the lamp body can be optimized, and the service life of the lamp body can be greatly prolonged on the premise that the luminescence performance of the lamp body is not impacted; through the arrangement of the heat dissipation column, the heat dissipation speed of the chip can be greatly improved, and thus the lamp body can be protected from ageing and yellowing, and the service life of the lamp body can be further prolonged.

Description

technical field [0001] The invention relates to an ultraviolet LED lamp bead. Background technique [0002] LED lights are widely used due to their good performance. [0003] In the prior art, the structure of the LED lamp bead is simple, and the LED lamp bead generates heat when it emits light. Therefore, it is easy to cause aging and yellowing of the lamp body, thereby affecting the performance of the LED lamp bead. Contents of the invention [0004] The ultraviolet LED lamp bead provided by the present invention aims to overcome the disadvantages of simple structure and easy aging and yellowing of the lamp body in the prior art. [0005] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the ultraviolet LED lamp bead includes a glass lamp body, a chip is arranged in the lamp body, a pair of pins are electrically connected to the chip, and the lamp body is located on the chip. A transparent silica gel ...
