Novel LED projection lamp

Abstract

The invention discloses a novel LED projection lamp; the novel LED projection lamp comprises a round base, an arc-shaped adjusting frame and a lamp body structure, wherein the arc-shaped adjusting frame is arranged at the center of the round base through a first rotating shaft and can rotate by 360 degrees transversely; the lamp body structure is arranged at the upper end of the arc-shaped adjusting frame and can rotate by 360 degrees in the longitudinal direction; the lamp body structure comprises a light source seat, an LED light source structure arranged in the light source seat, a surfacering cover, a light-transmitting sheet, a lens seat, a cylindrical base arranged below the light source seat and a driving device arranged in the cylindrical base; the bottom of the light source seatextends downwardly to form a plurality of heat dissipation columns and heat dissipation sheets which can enlarge the heat dissipation areas and can achieve ventilation and air convection; the heat dissipation columns and the heat dissipation sheets are located between the light source seat and the cylindrical base; the two sides of the cylindrical base are upward to be provided with a first rotating seat; a second rotating seat correspondingly matched with the first rotating seat is arranged on the two sides of the light source seat in a downward mode; and the upper end of the arc-shaped adjusting frame extends out of the inner side to form a second rotating shaft which can penetrate through the first rotating seat and the second rotating seat, so that the lamp body structure can rotate by360 degrees along the second rotating shaft.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a novel 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. The irradiation angle cannot be adjusted or the adjustment range is small, and it is difficult to adjust flexibly. Moreover, both the LED light source structure and the driving device will generate heat. There is no isolation measure or structure between the LED light source structure and the driving device of the existing LED floodlights. The heat between the two is easy to interfere with each other and affect the use of each other. In addition, the existing LED floodlights generally have the problems of low heat con...

AI Technical Summary

Problems solved by technology

The structure and light distribution method of the existing LED floodlights are relatively traditional and old, the irradiation angle cannot be adjusted or the adjustment range is small, it is difficult to adjust flexibly, the light angle is narrow, the light surface is small, there are dark areas in the light, and the light effect is average

Moreover, both the LED light source structure and the driving device will generate heat. There is no isolation measure or structure between the LED light source structure and the driving device of the existing LED floodlights. The heat between the two is easy to interfere with each other and affect the use of each other. In addition, the existing LED floodlights generally have the problems of low heat conduction and heat transfer efficiency and poor heat dissipation effect
