A kind of rotatable led downlight and its assembly method

Abstract

The invention discloses a rotatable LED downlamp, and belongs to the technical field of lamps. The downlamp comprises a base, wherein a fixing sleeve rod is arranged in the center of the bottom of thebase, a limiting sliding block is arranged in the inner cavity of the fixing sleeve rod in a sliding mode, and the bottom of the limiting sliding block is provided with a moving rod; and each of theleft side and the right side of the bottom of a fixing plate is provided with a fixing ring through a supporting rod, a round table is arranged in a lamp tube, a rectangular groove is formed in the bottom of the round table, a turnover mechanism is hinged to the right side of the top of the rectangular groove, a lamp holder is hinged to the bottom of the turnover mechanism, the right side of the top of the lamp holder is hinged to the round table, and a circuit board is arranged in the lamp holder. According to the rotatable LED downlamp, a hydraulic cylinder is started to extend a telescopicrod so that the lamp holder can be pushed to turn over by a certain angle; a rotating motor is used to enable the lamp tube to rotate, so that the illumination area of the LED lamp is increased, the light emitting dead angle is reduced, and the best illumination effect is achieved; and the downlamp is simple in structure, convenient to install and maintain, and capable of reducing the cost.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a rotatable LED downlight and an assembly method thereof. Background technique [0002] In the current LED lighting industry, the use of LED downlights is becoming more and more common. Compared with traditional vacuum incandescent light bulbs, LED light sources have extremely long working life, which is more than 10 times that of traditional lighting appliances, which effectively reduces costs. It has low power consumption, high luminous efficiency, and energy saving. It is the future development of lighting fixtures. Trend, but LED light is directional light, can not achieve real arbitrary angle light, many LED light sources need to be installed in traditional lamps, and because LED light is directional, installed in traditional lamps, sometimes the light-emitting surface will deviate from the normal The irradiation surface can not achieve the best effect. At present, the LED do...

Compared with traditional vacuum incandescent light bulbs, LED light sources have extremely long working life, which is more than 10 times that of traditional lighting appliances, which effectively reduces costs. It has low power consumption, high luminous efficiency, and energy saving. It is the future development of lighting fixtures. Trend, but LED light is directional light, can not achieve real arbitrary angle light, many LED light sources need to be installed in traditional lamps, and because LED light is directional, installed in traditional lamps, sometimes the light-emitting surface will deviate from the normal The irradiation surface can not achieve the best effect. At present, the LED downlight adopts rotating components to achieve a certain angle of rotation and increase the irradiation surface, but the installation cost is too high and the assembly steps are complicated. Therefore, we propose a rotatable LED tube Lamp and method of assembly thereof
