Description
Technical field
The invention belongs to non-portable illumination device or its system, especially belong to the LED street lamp.
Background technology
Because LED brightness height, power saving, in recent years be widely used on the various lighting installations, come light source as what mention among the ZL200620013271.1 with LED as solar street light, but it only considers the directionality of led light source, the led light source of but not considering dense arrangement is huge at the heat that luminescence process distributed, 1000/M
2LED energising 10 minutes, environment temperature reaches more than 70 degree, and the above temperature of 60 degree can make LED quicken light decay, and is big to its life-span influence.As: in 100,000 hours theoretical life-spans of the following simple grain LED of 60 degree, light decay is initial 50%, and spends when temperature surpasses 60, and its life-span only is 3000--5000 hour.The common operating ambient temperature of existing LED street lamp surpasses 70 degree, and adopts many group series design, and one bad, and whole lamp is bad, has increased the fault rate of whole lamp greatly.
LED is divided into two kinds of optically focused (lighting angle less than 90 degree) and zero diopters (lighting angle is spent greater than 90) according to the lighting angle difference.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, and a kind of LED street lamp of good heat dissipation effect long service life is provided.
The technical solution adopted in the present invention is a kind of LED street lamp, comprises power supply, lamp stand, lamp holder, and its main points are that lamp holder is fixed with heat sink, LED directly and heat sink join.
Because the LED issued light is a cold light, people have often ignored it also gives out heat, particularly dense arrangement in luminous LED, and the infringement that its heat of sending out causes himself is huge.The present invention has overcome the thinking inertia that traditional thinking set caused, and has creatively increased heat sink, and with LED directly and heat sink join.The present invention is just the fixed head of heat sink as LED, solved for a long time by the LED heat dissipation problem that people ignored, and prolonged the service life of street lamp, produced the technique effect of giving prominence to.
In order to obtain better radiating effect, the metal material with the good heat conductive effect in numerous materials is a first-selection, because aluminium has good heat conduction uniformity, heat sink preferably selects aluminium sheet.
The heat sink smooth surface becomes minute surface or by electroplating into minute surface, is preferably monoblock minute surface aluminium sheet and constitutes.Utilize that minute surface is reflective to carry out secondary optics to the diverging light that LED sent out and handle---reflection, increased the illumination of LED street lamp greatly, with the quantity that can reduce LED under the equiluminous, reduced heat dissipation capacity, produced beyond thought technique effect, the street lamp of feasible existing 9 meters height is increased to 25-28 illumination from the illumination of 15-16, satisfies the lighting requirement of street lamp, captured existing LED street lamp and can only reach the difficulty of 6 meters height, the quantity of LED lamp is also reduced to 768 by original 1200 simultaneously.
Operating voltage and power source voltage according to LED are carried out reasonable layout, several LED series connection are for a string, the operating voltage of LED is 3.2 volts, if the civil power with 220 volts is a power supply, can voltage be reduced to 3.2 volts multiple by transformation system makes several LED series connection or directly is 3.2 volts, when using solar energy as power supply, battery is an energy storage device, do not changing under the existing traditional storage battery voltage condition, increase by a divider resistance, allow LED be in optimum Working, as: when the voltage of battery was 12 volts of voltages, 3 LED connected to a string with a divider resistance; When the voltage of battery was 24 volts of voltages, 7 LED connected to a string with a divider resistance.Certainly also can pass through prior art, change the voltage request that battery tension satisfies the LED string.
A few string LED also are connected into bar and equidistantly arrange and be fixed on the heat sink, also can a few string LED and be connected into bar, and per two LED become one group to be fixed on the heat sink, and equidistant interval is arranged between every group.One group of optically focused LED and one group of zero diopter LED alternately arrange, make ground light according to evenly, eliminate LED point-like illumination defective.Concave arc cylinder shape in heat sink becomes, the circular arc angle is the 90--130 degree.Interior concaved circular cambered surface helps the scattered light of LED has been collected the effect of optically focused, reflect by minute surface, allow the maximization of LED issued light validity, while further eliminate LED point-like illumination defective, general circular arc angle is the 90--130 degree, is preferably 120 degree.
The invention has the advantages that: the heat dissipation design of specialty, the operating ambient temperature of LED is controlled in 30 degree, light decay is very little, so its life-span (refer to naked eyes can not aware illumination change) can reach 3--5 more than ten thousand hours, utilize that minute surface is reflective to carry out secondary optics to the LED issued light and handle, higher luminous flux makes the LED lamp than the LED lamp of assembling with the small-power of power bright about 50%, pole height can reach 6-12 rice, the series connection of employing group, long service life, the more existing LED street lamp of cost is cheap 50%, and it is convenient to change original road-light light-source, easy to maintenance, maintenance cost is low.
