Description

The LED street lamp
Technical field
The utility model relates to a kind of light fixture, especially relates to a kind of LED street lamp.
Background technology
Street lamp has considerable status in the urban lighting system, all can set up a large amount of street lamps in each city.Traditional street lamp mainly adopts high-pressure mercury lamp, and not only light efficiency is low, and illuminating effect is also undesirable, can't adapt to efficient, energy-conservation life idea now.
In recent years, because the continuous development of LED lighting engineering, the LED lamp becomes trend, the LED lighting engineering is applied to street lamp and the LED street lamp made also emerges in an endless stream.What the LED street lamp was different with traditional high-pressure mercury lamp street lamp is, the efficient white light-emitting diodes that the light source of high-power LED street lamp adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, the distinct advantages of LED lamps such as therefore the LED street lamp not only has light efficiency height, energy-saving and environmental protection, the life-span is long, response speed is fast also has safe advantage owing to supply voltage is low.
But the LED street lamp also has the shortcoming of self, and the caloric value of low-power LED is very little, all be to use high-power LED when making street lamp, the caloric value of high-power LED is bigger, and has the problem that is not easy to dispel the heat, and the brightness meeting obviously reduces after the heating, influences illuminating effect.
The heat dispersion difference is a LED street lamp problem demanding prompt solution, and the radiating mode of LED street lamp mainly contains: Natural Heat Convection, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.Install fan forced heat radiation mode system complex additional, reliability is low, and has increased the weight of street lamp because street lamp need be installed in eminence, the increase of weight can increase danger undoubtedly; Heat pipe and loop heat pipe radiating mode because cost is too high, are unfavorable for promoting on a large scale again.And street lamp have use at outdoor night, radiating surface is positioned at above the side and the restricted advantage that helps the natural convection air heat radiation such as less of build, therefore in general, the Natural Heat Convection mode is the reasonable radiating mode of LED street lamp.
And present LED street lamp is provided with the Water-resistant mirror layer in addition or the housing of LED street lamp is made Seal Design usually in order to obtain the excellent waterproof effect outside the light-distribution lens layer.The defective that the Water-resistant mirror layer is set is that light passes through the Water-resistant mirror layer and can produce light decay, the light decay of the reasonable lens of light transmission is about 10%, the not good material of light transmission also can produce more light decay, at this moment in order to improve the illuminating effect of LED street lamp, just must improve the brightness of LED road-light light-source, so not only waste electric energy, and owing to produced higher caloric value, the efficient of led light source is lower, forms vicious circle; And be sealing device with the housing global design of LED street lamp, then the heat that can make generation is difficult to heat radiation in seal cavity, also can influence the light efficiency of LED street lamp.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of light decay few LED street lamp, reduces the heat radiation burden of LED street lamp, the light efficiency and the service life of improving the LED street lamp.This LED street lamp has also alleviated weight when having improved heat dispersion, adapt to the specific (special) requirements of street lamp more.
