UVLED cooling device

Abstract

The invention relates to the field of UVLEDs, and particularly to a UVLED cooling device. The UVLED cooling device comprises a temperature detection module, a controller, a heat dissipation module anda constant-current driving module; and the temperature detection module is used for detecting the temperature of the UVLED module, the input end of the controller is connected with the temperature detection module, the output end of the controller is connected with a heat dissipation module and a constant-current driving module, the heat dissipation module is started or stopped according to output information of the controller, the constant-current driving module drives the UVLED module to work, and the constant-current driving module adjusts output current according to the output informationof the controller. According to the embodiment of the invention, air cooling can be carried out on the UVLED module, and when air cooling cannot meet the cooling requirement of the UVLED module, cooling is carried out by reducing the power of the UVLED module or stopping the UVLED module, so that the service life of the UVLED module is prolonged.

Description

technical field [0001] The invention relates to the field of UVLEDs, in particular to a UVLED cooling device. Background technique [0002] UVLED (ultraviolet LED) is now widely used in household appliances, food preservation, public health, municipal engineering and agricultural facilities and other fields. In the above applications, the working time of the ultraviolet LED module is relatively short and will not affect the module. The service life has a great influence. [0003] However, in some specific use occasions, such as ultraviolet disinfection and sterilization of tap water and sewage in municipal engineering, in such an application environment, the UV LED module will continue to work for a long time, which will cause the life of the UV LED module to be shortened due to heat problems. Seriously shortened, which requires the UV LED module itself to have a protective function. The current UV LED module has a relatively simple control function, and its active cooling ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem in the prior art that the UVLED module continues to work when it is overheated or overcurrent and affects the service life of the UVLED module, the present invention provides a UVLED cooling device, which can effectively cool down the UVLED module, thereby improving its service life.
