Description
Technical field
The present invention relates to a kind of LED lamp, especially a kind of solar LED (Light Emitting Diode) lamp.
Background technology
Solar street light consists of the following components: solar cell, battery, control inverter, light-operated and timer, illuminator.Solar street light is a work system of control automatically, as long as the mode of operation of this system of setting will be controlled work automatically.Control model generally is divided into three kinds: light-operated startup, light-operated closing; Timing control starts and timing control is closed; Light-operated startup, timing control are closed, and we generally select this pattern working method, and sensing control started lamp work when lamp hanged down to setting value at sunlight, carried out timing simultaneously and began.When timing just quits work during to setting-up time.The solar cell of native system has two kinds of effects: one, be charge in batteries by day; Two, do light control sensor, with the charging and discharging of RC element.We are general to adopt 18 watts or 36 watts of low-pressure sodium lamps as light source, because its light efficiency is the highest in light source.Solar street light is desirable road illuminating lamp, and along with the raising of people's life and the continuous development of society, it will be widely used, and the light that makes the sun grant the earth is human illumination at night.
Though incandescent lamp that general lighting is used and halogen tungsten lamp low price, light efficiency low (power consumption in vain of the fuel factor of lamp), the life-span is short, maintenance workload is big, but if throw light on white light LEDs, not only the light efficiency height, and long (stream time is more than 10000 hours), almost Maintenance free of life-span.But the problem that Solar lamp exists is exactly adopt common photoelectric pond conversion ratio low, and cost to be higher, universal comparatively difficulty.
Summary of the invention
At the problems referred to above, the invention provides a kind of solar LED (Light Emitting Diode) lamp.
A kind of solar LED (Light Emitting Diode) lamp; mainly by the LED lamp holder; the convex lens group; thermoelectric generator; light-sensitive element and super capacitor assembly are formed; it is characterized in that thermoelectric generator is to be composed in series by 3-4 thermo-electric generation sheet; the thermo-electric generation sheet is by a block semiconductor thermoelectric pile; heat conduction copper sheet and low temperature copper sheet are formed; heat conduction copper sheet outer surface is comparatively coarse; and the heat conduction copper sheet of its each thermo-electric generation sheet is positioned at the same side; the low temperature copper sheet is positioned at opposite side backlight; the convex lens group is made up of a plurality of convex lens; and be provided with tracking means; the focus spot that convex lens are formed just in time full illumination in the heat conduction copper sheet side of thermo-electric generation sheet; make it produce the high temperature temperature difference; heat conduction copper sheet side is equipped with overtemperature protection system; make its high temperature can be above 180 ℃; the voltage input super capacitor that produces stores, and can open super capacitor automatically and give the power supply of LED lamp holder when light-sensitive element finds that light is more weak.
Remarkable result of the present invention is that the thermo-electric generation sheet is applied in the solar illuminating system, adopt the LED lamp as illuminating lamp, the long-time irradiation of light that the convex lens group focuses on can reach the high temperature more than 200 ℃, low temperature copper sheet end is owing to be positioned at shady face, its temperature generally can be not high, similar with room temperature, this makes the thermo-electric generation sheet can produce higher voltage, can satisfy lighting demand.

Wherein: 1, the convex lens group; 2, the heat conduction copper sheet; 3, thermoelectric generator; 4, the LED lamp holder; 5, the low temperature copper sheet; 6, super capacitor; 7, light-sensitive element.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing: thermoelectric generator 3 is to be composed in series by 3-4 thermo-electric generation sheet; the thermo-electric generation sheet is by a block semiconductor thermoelectric pile; heat conduction copper sheet 2 and low temperature copper sheet 5 are formed; heat conduction copper sheet 2 outer surfaces are comparatively coarse; and the heat conduction copper sheet 2 of its each thermo-electric generation sheet is positioned at the same side; low temperature copper sheet 5 is positioned at opposite side backlight; convex lens group 1 is made up of a plurality of convex lens; and be provided with tracking means; the focus spot that convex lens are formed just in time full illumination in heat conduction copper sheet 2 sides of thermo-electric generation sheet; heat conduction copper sheet side is equipped with overtemperature protection system; make its high temperature can be above 180 ℃; make it produce the high temperature temperature difference; when the temperature of heat conduction copper sheet 2 is higher than 180 ℃; the convex lens group can be left focus automatically from heat conduction copper sheet 2 sidesways; when being lower than 170 ℃, the temperature of heat conduction copper sheet 2 focuses on irradiation once more; the voltage input super capacitor 6 that produces stores; can open super capacitor 6 when light-sensitive element 7 finds that light is more weak automatically gives the LED lamp holder 4 power supplies; because common thermo-electric generation sheet can produce 3.5V when 60 ℃ of temperature difference; the electric weight of 3A-5A; so can produce 30V during for focus temperature (according to 150 ℃ of calculating of the temperature difference); the electric weight of 3A-5A; the i.e. power of about 90W-150W can satisfy the lighting demand of common street lamp (90W) fully.
The invention has the beneficial effects as follows the thermo-electric generation sheet is applied in the solar illuminating system, adopt the LED lamp As illuminating lamp, the long-time irradiation of light that the convex lens group focuses on can reach the high temperature more than 200 ℃, and is low Temperature copper sheet end is owing to be positioned at shady face, and its temperature generally can be not high, and similar with room temperature, this makes thermo-electric generation Sheet can produce higher voltage, can satisfy lighting demand, and its conversion efficiency of thermoelectric can surpass 30%, and And the more common photovoltaic cell of cost is much lower.
