Description

Technical Field

[0001] The utility model relates to the technical field of mosquito repellent lamps, in particular to a transparent ceramic light source for mosquito repellent lamps. Background Art

[0002] Mosquito-killing lamps use the fact that mosquitoes have a clear tendency to ultraviolet light and blue-violet light to trap mosquitoes. They are used in some large buildings, industrial plants, storage areas, public waiting halls, and other scenes. Since mosquito-killing lamps need to be cleaned regularly and are relatively passive, mosquito repellent lamps came into being. However, the heat dissipation performance of the light source of traditional mosquito repellent lamps is poor, and they frequently malfunction after working for a long time, which can no longer meet the current usage needs.

[0003] Therefore, how to provide a transparent ceramic light source for a mosquito repellent lamp to improve the heat dissipation performance of the light source has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a transparent ceramic light source for a mosquito repellent lamp, so as to improve the heat dissipation performance of the light source.

[0005] The utility model is implemented as follows: a transparent ceramic light source for a mosquito repellent lamp, comprising:

[0006] A copper substrate with a circular crystal-fixing surface in the middle;

[0007] A plurality of blue light chips are arranged in the solid crystal surface and connected to each other in series and parallel;

[0008] A plurality of heat-conducting columns are vertically arranged in the die-bonding surface and are higher than the blue light chip;

[0009] A fluorescent ceramic sheet is connected to the top of each of the heat-conducting pillars and is located directly above each of the blue light chips.

[0010] Furthermore, the irradiation direction of the blue light chip is upward.

[0011] Furthermore, the thermally conductive column is a sapphire thermally conductive column.

[0012] Furthermore, the size of the fluorescent ceramic sheet matches the crystal-fixing surface.

[0013] The advantages of the utility model are:

[0014] By setting a copper substrate, a thermally conductive column and a fluorescent ceramic sheet, the thermally conductive column is vertically arranged between the copper substrate and the fluorescent ceramic sheet, and the blue light chip is arranged in the solid crystal surface of the copper substrate, and the irradiation direction is toward the fluorescent ceramic sheet. The heat generated by the blue light chip during operation is transferred to the copper substrate for heat dissipation, and the copper substrate simultaneously transfers the heat to the fluorescent ceramic sheet through the thermally conductive column for heat dissipation, that is, two-way heat dissipation is performed through the copper substrate and the fluorescent ceramic sheet, and the copper substrate and the sapphire thermally conductive column both have better thermal conductivity, which ultimately greatly improves the heat dissipation performance of the light source.

[0022] The technical solution in the embodiment of the utility model is to solve the above-mentioned problem, and the overall idea is as follows: the copper substrate 1 and the fluorescent ceramic sheet 4 are connected by the thermal conductive column 3, and the heat generated by the blue light chip 2 during operation is bidirectionally dissipated through the copper substrate 1 and the fluorescent ceramic sheet 4, and the copper substrate 1 and the sapphire thermal conductive column 3 both have better thermal conductivity to improve the heat dissipation performance of the light source 100.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Please refer to Figures 1 to 3 As shown, a preferred embodiment of a transparent ceramic light source 100 for a mosquito repellent lamp of the utility model comprises:

[0025] A copper substrate 1, with a circular crystal-fixing surface 11 in the middle; the copper substrate 1 is used to carry the ceramic light source 100; the crystal-fixing surface 11 is used to install (crystal-fix) the blue light chip 2 and the heat-conducting column 3;

[0026] A plurality of blue light chips 2 are arranged in the solid crystal surface 11 and connected in series and parallel with each other; the blue light chip 2 is used to emit blue light with a wavelength of 400-500nm to the fluorescent ceramic sheet 4, so as to stimulate the fluorescent ceramic sheet 4 to emit yellow light with a wavelength of 530-590nm that mosquitoes do not like, so as to achieve the effect of repelling mosquitoes. In the specific implementation, it is sufficient to select a blue light chip that can realize this function from the existing technology, and it is not limited to any model, such as Sanan chip S-35EBMUD-A-CH;

[0027] A plurality of heat-conducting pillars 3 are vertically arranged in the crystal-fixing surface 11 and are higher than the blue light chip 2, and are used to conduct the heat of the copper substrate 1 to the fluorescent ceramic sheet 4;

[0028] A fluorescent ceramic sheet 4 is connected to the top of each of the heat-conducting pillars 3 and is located directly above each of the blue light chips 2. It is used for heat dissipation of the ceramic light source 100 and emits yellow light with a wavelength of 530-590nm.

[0029] The power of the ceramic light source 100 is 600W, the voltage is 108V, the current is 5600mA, and the light efficiency is >160lm / W.

[0031] The thermally conductive column 3 is a sapphire thermally conductive column, which has a good thermal conductivity.

[0033] Working principle of this utility model:

The heat generated by the blue light chip during operation is transferred to the copper substrate for heat dissipation, and the copper substrate simultaneously transfers the heat to the fluorescent ceramic sheet through the thermally conductive column for heat dissipation, that is, two-way heat dissipation is performed through the copper substrate and the fluorescent ceramic sheet, and the copper substrate and the sapphire thermally conductive column both have better thermal conductivity, which ultimately greatly improves the heat dissipation performance of the light source.
