Wall-switch-type light-dimming and color-mixing LED ceiling lamp

Abstract

The invention discloses a wall-switch-type light-dimming and color-mixing LED ceiling lamp which comprises a radiating base body, an upper face cover, a lower face cover, a driving power source disposed in the radiating base body, a first light guide plate, a second light guide plate, a first LED module, a second LED module and a third LED module. The upper face cover and the lower face cover are arranged on the upper end face and the lower end face of the radiating base body respectively, the first LED module, the second LED module and the third LED module are connected with the driving power source electrically, the first LED module and the second LED module are disposed on the inner sides of the first light guide plate and the second light guide plate respectively, and the third LED module is arranged on the lower surface of the radiating base body. Light emitted by the LED modules is projected to a lighting area through the first light guide plate and the second light guide plate, so that output of upwards-emitting light, downwards-emitting light and horizontal light is realized respectively; by enabling the LED modules to contact with the radiating base body, radiating of the LED modules can be realized effectively, normal work of the LED modules is guaranteed, and service life of the LED modules is prolonged.

Description

technical field [0001] The invention relates to a ceiling lamp, in particular to a wall switch type LED ceiling lamp for dimming and color adjustment. Background technique [0002] At present, LED lighting applications are developing rapidly. Due to its long life, energy saving, environmental protection and efficiency improvement, it will become more and more popular to replace incandescent and fluorescent lamps in daily lighting. [0003] Ordinary LED ceiling lamps have relatively simple functions, and only have the function of turning on the light when the power is turned on; although there are dimming functions on the market, they are expensive and need to be equipped with a separate dimmer. [0004] The existing LED lights have a built-in substrate with multiple LEDs on the surface. Most of the substrates are planar, and the substrate is basically fixed in the metal casing. Due to the strong directivity of the LED light, the light within the lighting angle of the LED Ve...

[0004] The existing LED lights have a built-in substrate with multiple LEDs on the surface. Most of the substrates are planar, and the substrate is basically fixed in the metal casing. Due to the strong directivity of the LED light, the light within the lighting angle of the LED Very strong, but the surrounding area is relatively dim, especially as a ceiling light, LEDs cannot shine upwards
