High-heat dissipation LED module street lamp cap with adjustable angle

Abstract

The invention discloses a high-heat dissipation LED module street lamp cap with an adjustable angle, which comprises a fixed seat, a first support and a second support which are fixedly connected with the fixed seat, a positioning bracket used for fixing the first support and the second support and an LED module arranged between the first support and the second support. Positioning screws and positioning devices are arranged at both ends of the LED module; U-shaped bayonets are arranged on the first support; tap position clamping holes are arranged on one side of the U-shaped bayonets; the distance from each tap position clamping hole to each U-shaped bayonet is the same as the axial distance from each positioning contact to each connecting screw; the second support is correspondingly provided with the U-shaped bayonets of which the positions and the number are the same as those of the first support; the positioning screws of the positioning devices are clamped in the U-shaped bayonets of the second support; the connecting screws are clamped in the U-shaped bayonets of the first support; and the positioning contacts are clamped in the tap position clamping holes. The LED module street lamp cap has the advantages of simple operation, stable positioning, convenient assembly, environmental protection and energy conservation.

Description

【Technical field】 [0001] The invention relates to a lamp holder of a street lamp, in particular to a lamp holder of an LED module street lamp with adjustable angle and high heat dissipation. 【Background technique】 [0002] LED semiconductor lighting is the fourth generation of electric light source after incandescent lamps, fluorescent lamps and rare gas lamps. Because of its high efficiency, long life, energy saving, environmental protection and other advantages, it has become the competition of light source and lamp research institutions and lamp lighting manufacturers all over the world. The goal of development and efforts to obtain is the star industry in the future lighting field. With the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), the performance of white-emitting LED semiconductor solid-state light sources has been continuously improved and entered into a practical stage. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the light sources used for street lighting include: incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, etc. The main disadvantages of these lamps are: 1. Not environmentally friendly: heavy metals such as mercury, lead, and arsenic are harmful to the environment. Harmful; 2. High energy consumption; 3. Short life

[0008] At present, after most street lamps are installed and fixed, the working state of the irradiation angle is determined, so it is difficult to adjust the irradiation angle of the street lamp according to the width of the road surface during use.

[0009] There are also many domestic street lamps whose rotating structure is positioned by the friction force of the relative rotation of the two parts. The disadvantage of this method is that the magnitude of the friction force is not easy to control, and after positioning, it is easy to shift due to external vibrations and other influences.

[0010] At present, there are many kinds of LED street lamps at home and abroad, and their performance is uneven. Due to the constraints of LED lamps in terms of quality and heat dissipation requirements, it is difficult to meet the lighting needs of ultra-high-power LED street lamps.
