Arc-shaped LED projection lamp

Abstract

The invention discloses an arc-shaped LED projection lamp; the arc-shaped LED projection lamp comprises an arc-shaped mounting clamp, an L-shaped mounting frame, a lamp body structure and a driving device, wherein the arc-shaped mounting clamp can be clamped on a mounting column; the L-shaped mounting frame is mounted on the arc-shaped mounting clamp through a first rotating shaft and can rotate transversely for 360 degrees; the lamp body structure is mounted on the L-shaped mounting frame and can rotate so as to adjust the mounting angle and the illuminating angle; the driving device is connected with the lamp body structure; the lamp body structure is in an arc shape, and the section of the lamp body structure is rectangular; a plurality of mounting hole columns are arranged at differentpositions of the back surface of the lamp body structure; the L-shaped mounting frame is mounted on the applicable mounting hole columns through a second rotating shaft, so that the mounting positionbetween the lamp body structure and the L-shaped mounting frame can be adjusted; and the lamp body structure can rotate around the second rotating shaft, so that the mounting angle and the irradiation angle of the lamp body structure in the longitudinal direction can be adjusted.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an arc-shaped LED floodlight. Background technique [0002] With the continuous breakthrough of LED technology, especially the successful development of high-power and high-efficiency LEDs, LEDs are widely used in various lighting fields, such as LED floodlights. The structure and light distribution method of the existing LED floodlights are relatively traditional and old, and generally have a linear light emitting surface, which cannot meet the light source projection requirements in arc-shaped places, and the light-emitting angle is narrow, the light-emitting surface is small, and the light-emitting effect is average. , and the LED light source generally only passes through the light distribution of the light-transmitting cover once and then directly emits light, the light is not uniform and soft, and it is prone to dazzling problems, the light utilization rate is low, the light ...

Problems solved by technology

The structure and light distribution method of the existing LED floodlights are relatively traditional and old, and generally have a linear light emitting surface, which cannot meet the light source projection requirements in arc-shaped places, and the light-emitting angle is narrow, the light-emitting surface is small, and the light-emitting effect is average. , and the LED light source generally only passes through the light distribution of the light-transmitting cover once and then directly emits light, the light is not uniform and soft, and it is prone to dazzling problems, the light utilization rate is low, the light efficiency is low, the irradiation intensity is insufficient, and the luminous effect poor

In addition, the angle adjustment of the existing LED floodlights is very limited, the light emitting surface is narrow, and it is difficult to adjust flexibly

Moreover, the existing LED floodlights generally have the problems of low heat conduction and heat transfer efficiency and poor heat dissipation effect.
