Embodiment Construction

[0027] The present invention will be further described below in conjunction with the drawings.

[0028] Such as figure 1 , figure 2 As shown, it includes an LED modular light source, a lamp housing 1, a number of heat dissipation bases 5, a number of aluminum-based circuit boards, a lampshade, a waterproof rubber strip, and a shell containing a glass lampshade; the lamp housing consists of a table-shaped bottom plate, two side panels on both sides, 2, The middle side plate 3 and the adjusting bracket 4 are formed. The side plates on both sides of the lamp housing are equipped with adjusting brackets 4 at the front and rear ends. The heat dissipation base 5 with aluminum-based circuit board is fixedly installed with the adjusting bracket 4 through the middle side plate 3. The LED light source is welded on the aluminum-based circuit board, and the adjusting bracket There is a groove for adjusting the position of the bolt. The angle between the plane of the heat dissipation base 5 ...

Abstract

The invention provides an LED street lamp with adjustable light path and angle. The LED street lamp comprises an LED light source and a heat dissipation system thereof; an LED light source module is fixed on a heat dissipation pedestal through a high heat-conducting material; serrated heat dissipation passages formed on the heat dissipation pedestal and the surface of the lamp can improve the heat dissipation property of the LED light source module and prolong the service life of an LED; and the heat dissipation pedestal is fixed in the lamp through a bracket. The included angle of the plane of the heat dissipation pedestal and the pavement can be adjusted by adjusting the bracket so as to fulfill the purposes of adjusting the luminous light path and angle and adjusting the illumination area of the pavement.

Description

Technical field [0001] The invention relates to LED lighting technology, in particular to an LED street lamp with adjustable light length and angle Background technique [0002] As a new solid-state light source in the 21st century, LED has the advantages of energy saving, environmental protection, safety, easy drive, small size, long life, rich colors, and high reliability. It is widely used in traffic signal indication, backlight, general lighting, street lights and other fields. [0003] The LED luminous tube is driven by direct current. Compared with ordinary incandescent lamps, the luminous efficiency is increased by at least 4 times, the energy consumption is only 1 / 10 of that of incandescent lamps, and the life span is extended by 50 times. [0004] Unlike traditional light sources, LEDs cannot radiate the heat generated by themselves through thermal radiation, but can only dissipate heat through heat conduction, convection, etc. Therefore, in the actual application process, t...
