Title:
EFFICIENT ENERGY-SAVING LED PROJECTION LAMP
Document Type and Number:
WIPO Patent Application WO/2023/035182
Kind Code:
A1
Abstract:
The present invention relates to the technical field of LED projection lamps. Disclosed is an efficient energy-saving LED projection lamp. The LED projection lamp comprises a chassis and an LED projection lamp body. A sliding member is slidably connected to the top of the chassis, a fixed tube is assembled at the top of the sliding member, and a limiting mechanism used for limiting the sliding member to move at the top of the chassis is assembled at one end of the fixed tube, such that it is convenient to adjust a transverse position of the LED projection lamp body. An angle adjustment mechanism used for adjusting an irradiation angle of the LED projection lamp body is assembled inside the fixed tube, the angle adjustment mechanism comprises a rotating block, and the rotating block is located on the outer side of the fixed tube and rotatably connected to the fixed tube. According to the present invention, by means of the angle adjustment mechanism, the irradiation angle of the LED projection lamp body can be better adjusted, thereby reducing the time for adjusting the angle of the LED projection lamp body, and achieving higher efficiency; and by means of the limiting mechanism, the position of the LED projection lamp body can be adjusted when the LED projection lamp body operates, thereby improving the applicability of the device.
