Abstract

The invention provides a light-uniform heat-dissipation type photoelectricity separation light-emitting diode (LED) ceiling lamp with an installation plate. The light-uniform heat-dissipation type photoelectricity separation LED ceiling lamp with the installation plate mainly solves the problems that an existing ceiling lamp power supply is poor in power heat-dissipation performance, and cannot be run in high-temperature and high-humidity environments, and the structure in the prior art is not reasonable. The light-uniform heat-dissipation type photoelectricity separating LED ceiling lamp with the installation plate comprises an LED light source, an LED power supply, a ceiling lamp shell body and a ceiling lamp shade, wherein the LED power supply comprises a circuit board, a power box body and a power box cover. According to the light-uniform heat-dissipation type photoelectricity separation LED ceiling lamp with the installation plate, an installation mode that an idle unit is vertically arranged on the circuit board is adopted, so that heat-dissipation can be easily carried out, the idle unit can be independently replaced, the light-uniform heat-dissipation type photoelectricity separating LED ceiling lamp can be used in the high-temperature and high-humidity environments, and with adoption of the vertical arrangement, an air channel can be formed, so that the fact that heat is taken away by flow circulation of air flow is benefited, and a heat-dissipation effect can be further improved. The power box cover is reasonable in setting of duty ratio, high in strength, facilitates processing, and low in cost.
