Abstract
The utility model discloses an LED streetlamp comprising a lamp head, a power supply mounting part, a fixed connecting piece, an aluminum radiator structure, an LED light source and an LED substrate. The aluminum radiator structure is arranged behind the LED substrate, the LED substrate has three surfaces and a trapezoidal section. Due to the adoption of the technical scheme, the LED streetlamp is wide in lighting range and high in brightness, and has extremely good quakeproof and windproof properties and a heat-radiating function and also has extremely good technical advantages.
Description
Technical field
The utility model relates to a kind of LED street lamp, belongs to lighting field.
Background technology
Light-emittingdiode (English: Light-Emitting Diode, be called for short LED) be a kind of semiconductor element.At the beginning indicator lamp, display boards etc. of being used as more; Along with the appearance of white light emitting diode, also be used as illumination.
It is the new type light source of 21 century, has long, conventional light source such as the cracky advantage that can't compare with it not of efficient height, life-span.When adding forward voltage, the light-emitting diodes physical efficiency is sent monochrome, discontinuous light, and this is a kind of of electroluminescent effect.Change the chemical composition of the semi-conducting material that is adopted, can make light-emittingdiode be emitted near ultraviolet ray, visible light or ultrared light.
Because LED operating voltage low (only 1.5-3V); Can active illuminating and certain brightness is arranged; Brightness can use voltage (or electric current) to regulate again, and itself is shock-resistant again, anti-vibration, life-span are long, so has played increasing application in the demonstration field; Especially be utilized in the street lamp field, have brightness height, long technological merit of life-span.
But, because street lamp is in the environment of wind and weather for a long time, be easy to break down, therefore, produced certain obstacle for promoting the use of of LED street lamp.
The utility model content
The utility model provides a kind of long service life, changes the simple LED street lamp to the high shortcoming of transitional street lamps fault rate, and this street lamp has technological merit preferably.
The utility model solves the problems of the technologies described above the technical scheme that adopted like following description:
A kind of LED street lamp wherein, comprises lamp holder, power supply installation portion, fixed connecting piece, aluminium matter radiator structure, led light source and LED substrate, and the back of said LED substrate is provided with said aluminium matter radiator structure,
Wherein, said LED substrate is the structure that belongs to three faces, and its cross section is a trapezoidal structure.
Further, preferred construction is that the material of described power supply installation portion is that aluminium alloy or aluminum are processed.
Further, preferred construction is that said led light source is provided with a plurality of, and is evenly distributed on the said LED substrate.
The present invention has taked after the technique scheme, and its illumination range is wide, brightness is high, and has well shockproof scratch resistant and heat sinking function, has good technological merit.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the structural representation of the utility model LED street lamp.
The specific embodiment
Come the utility model is described below in conjunction with accompanying drawing and specific embodiment.
Wherein, Fig. 1 is the structural representation of the utility model LED street lamp.
As shown in the figure, said LED street lamp wherein, comprises lamp holder 1, power supply installation portion 2, fixed connecting piece 3, aluminium matter radiator structure 4, led light source 5 and LED substrate 6, and the back of said LED substrate 6 is provided with said aluminium matter radiator structure 4.
Wherein, said LED substrate 6 is the structures that belong to three faces, and its cross section is a trapezoidal structure, and for example, the no top of canal section formula as shown in Figure 1 is trapezoidal.
Further, in the preferred embodiment, the material of described power supply installation portion 2 is that aluminium alloy or aluminum are processed.
And said led light source 5 is provided with a plurality of, and is evenly distributed on the said LED substrate 6.
Wherein, because the LED substrate is chosen above-mentioned structure, it can combine optical lens (secondary souce) to handle, and wideer road surface illumination patterns curve is more uniformly arranged, and also is that illumination range is big;
And the material of power supply installation portion 2 is a metallic aluminium, in use also possesses stronger wind resistance shock resistance, can more reasonably ensure led light source avoid the energising course of work in owing to temperature effect produces the light decay phenomenon.
In a word, the invention illumination range is big, and the wind resistance shock resistance is better in the use, has extraordinary technological merit.
Above-mentioned specific embodiment only is exemplary, and under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
