Problems solved by technology

Also, in the greenhouse, because the growth of plants is often closely related to the carbon dioxide content in the air and the humidity of the environment in the greenhouse, and people often cannot directly obtain the information of the carbon dioxide content and humidity in the greenhouse, so the development of a detection system Humidity, carbon dioxide content function and LED lights with alarm function can effectively ensure the healthy growth of plants

Abstract

The invention relates to the technical field of illumination devices, in particular to a large power LED lamp and application thereof in a greenhouse. The large power LED lamp comprises an installation portion, a radiator is arranged at the installation portion, a lampshade is arranged on the radiator, a substrate where LED light sources are installed is further arranged on the radiator, at least two LED wafers are arranged on the substrate, temperature sensors and control circuits for controlling on and off of the LED wafers are arranged in the LED wafers, a control main board connected with the temperature sensors and the control circuits is arranged on the substrate, and at least one through cooling channel is further arranged on the substrate. The large power LED lamp can effectively solve the problem of luminous decay and the problem caused by cooling in the greenhouse with the high environment temperature and the requirement for long-term illumination.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an LED high-power lamp and its application in greenhouse lighting. Background technique [0002] The heat dissipation problem of LED lamps has always been a key issue restricting the service life of LED lamps. At present, there are many ways to solve the heat dissipation of LED lamps, but basically they use heat conduction and heat convection to reduce the heat generated by LED chips. For example, develop heat-conducting materials with high thermal conductivity, install fans that can generate heat convection in LED devices, and install heat-exchange channels containing heat-exchange fluids on radiators. For ordinary LED lamps, these methods reduce the LED chip junction temperature to a certain extent and improve the service life of the lamps. However, for LED lamps that require continuous lighting or LED lamps that need to be illuminated in a high temperature environme...
