As everyone knows, LED is a kind of electroluminescence device, and its basic physical process is the transformation of electric energy to luminous energy.The so-called power that improves LED promptly is to improve electricity input energy, can obtain big as far as possible luminous power output simultaneously again.Usually the opto-electronic conversion power of luminous energy (luminous flux) meaning that the unit input power is produced is called for short light efficiency.Strengthen input power and can improve the LED light efficiency, but a large amount of practice shows that LED can not too strengthen input power that fundamental cause is because LED can emit a large amount of heat in the course of the work, and the tube core junction temperature is risen rapidly, input power is high more, and heating effect is big more.The rising of temperature will cause the variation and the decay of device performance, and led light source may lose efficacy when temperature surpasses 60 ℃.The cooling of diode is the subject matter that Machine Design and circuit-board laying-out need be considered.Temperature can influence the output brightness of device, when device when environment temperature is raised to 120 ℃, brightness will descend nearly 35%.The die temperature of LED also can influence the emission wavelength of device, and wavelength almost can change 4-9nm under 100 ℃ variations in temperature.The heat that produces in the time of light emitting diode must being worked is dispersed into the operate as normal that could guarantee light emitting diode in the extraneous air rapidly, promptly needs the temperature of lamp interior is directed on the street lamp housing.

Lighting source of the present utility model is the modularized combination type structure, and each module 18 LEDs light emitting diode according to calculating, is selected the circuit structure of six lamp pearl series connection for use, and promptly 18 light emitting diodes of each module are formed the matrix arrangement.As long as the utility model embodiment selects the i.e. LED light emitting diode of 72 1W power of four modules for use, 72W power can reach 12 meters bar illuminance of grounds of actual measurement greater than 50lx.The illumination requirement that has surpassed high-grade main trunk road.
Key of the present utility model is intelligent electric power design (Fig. 4).The LED illuminator need be powered by means of constant current, it is to utilize linearity or switching mode AC/DC voltage-stablizer to provide the constant current power supply in conjunction with specific feedback circuit for LED that the constant current of main flow at present drives design, in order to satisfy the voltage requirements of most countries in the world, this project AC/DC exchanges the input service scope and is selected in 90-300V.Output voltage require safe voltage (AC36, DC48V) in the scope, the optimum operating voltage of LED light emitting diode is 3.02V-3.4V, press LED standard operation voltage 3.3V and designs, it is 19.8V that six series connection require dc voltage, standard is decided to be 20V ± 0.2V.The standard output current is according to 350mA, if 12 tunnel outputs need 4200mA altogether.
At present, the LED design industry exists the impercipient problem of the demand of special trade, normal some unpractical power supply designs that adopt in the design.Ignored the influence of the variation of electric current to the led light source life-span, the distribution inequality takes place in electric current in the ifs circuit, the LED light-emitting diode luminance that obtains big electric current increases and increases along with electric current, and variation may be brought up to 40 lumens from 20 lumens, has raise but the operating temperature of LED is also corresponding.In case temperature surpasses the limit warm spot of LED, will influence life-span and the reliability of LED, therefore, light decay just takes place soon after causing a lot of LED illuminations to light, the bright dark inequality of lamp pearl in the same light fixture has shortened service life of LED illumination greatly.This is a sixty-four dollar question in the design constant current driving process.Therefore, the utility model after the output of high efficiency constant current switch power supply, adopted again independently efficient DC/DC constant-current drive circuit with the Current Control of each paths of LEDs illumination in constant scope.Load same electric current to each string LED light emitting diode and guarantee uniform white light.The basic circuit of DC/DC constant voltage power supply adopts feedback resistance RFB1 and RFB2, and when load current changed, VFB also changed thereupon, and the DC/DC voltage-stablizer is adjusted the positive terminal voltage of LED then by the variation of perception VFB, makes the electric current of the LED that flows through keep constant.Here it is utilizes DC/DC voltage-stablizer FB feedback end to realize the principle of constant voltage to the constant current conversion.
Intelligent road lighting apparatus requires to reduce its light intensity after one period free time.This just requires LED to have adjustable light intensity, and such adjusting should remove to influence every road forward current in the same way, to avoid possible hue coordinate skew.The electric current that utilizes small-sized digital to analog converter to control the LED light emitting diode of flowing through can obtain uniform brightness.Adopt the converter of 6 bit resolutions among the utility model embodiment, have the MAX5365 of SPI interface, 32 grades of brightness regulation can be provided.Because forward current can influence hue coordinate, so the LED white light can change along with intensity variations.But this is not a problem, because identical forward current can make each diode in this group all send same light.
In addition, the optical efficiency of LED illuminator not only depends on LED constant current drive scheme, and is also closely related with the heat dissipation design of whole system.The rising of temperature will cause the variation and the decay of device performance, in case above 75 ℃, led light source will lose efficacy, and caused the road dark, may cause the road safety accident when temperature, be extremely dangerous.In the utility model embodiment, added temperature control system, temperature sensor is arranged on the limit (Fig. 2) of LED light emitting diode, when the heat source temperature that detects LED light emitting diode itself surpasses 70 ℃, temperature-control circuit is taken measures automatically, reduces LED light emitting diode operating current, and operating temperature is descended, can prolong the life-span of LED light emitting diode, guarantee the street lamp work safety.
The road lighting working time is generally 6 of every nights, and when entering the late into the night, electrical network is at a low ebb to some the next mornings six, because the adjusting time difference in power plant may be born the input voltage that is higher than 300V.Conventional power supply driver often damages in the moment that electrical network is adjusted, for fear of these unfavorable factors, and the antisurge high voltage protection pattern that the utility model adopts.Automatically monitoring input voltage when voltage surpasses working limit, is closed oscillating circuit, and Switching Power Supply is quit work; When the surge voltage peak value drops to below the 300V, Switching Power Supply is recovered automatically, because this process is moment (nanosecond time) to take place, has both guaranteed the safety of power supply and light source, be unlikely to again to cause high voltage to quit work, it is dark and the road safety accident takes place to form moment.
Traditional Artificial Control street lamp mode is wasted a large amount of electric energy just in case error can cause street lamp to be lighted by day.The utility model utilizes photo resistance that ambient brightness is detected automatically, and the resistance of photo resistance changes along with the intensity of available light, and photo resistance is the photoelectric cell with inner photoeffect work.Adopt semi-conducting material manufacturing, the utility model adopts the photo resistance (NTC) of negative temperature coefficient; Its resistance reduces with the increase of intensity of illumination, uses intelligent MCU chip controls system, uses optoelectronic switch as trigger mechanism.Under a photo resistance and light source acting in conjunction, the resistance of photo resistance changes, and touches the optoelectronic switch action, start intelligent MCU chip controls system, realization opens and closes automatically the LED road lamp power supply, can prevent the Artificial Control error, and cause the wasting phenomenon of lighting street lamp under the sunlight.Realization need not the intelligence operation that the people manages.
The utility model adopts characteristic secondary optics to handle in illumination design, puts the prefocus cup of different angles on each led light source, makes the light source refraction and accumulates on the target, can increase street lamp illumination 2-3 doubly.According to the road Lighting Design requirement, irradiates light width radius on the ground is 1.5 times of light source height, adopt an optical treatment of prefocus cup form, can only make light-ray condensing and can not make the light diffusion, must take DIFFUSION TREATMENT again one time, make light pass through the refraction of diverging lens, the utility model has adopted telescope principle (as shown in Figure 5), handle by secondary optics the LED illuminating ray, enlarge and increased the illumination uniformity on the path area, thereby played energy-efficient purpose.
This novel practical can be widely used in city illumination, tunnel illumination, highway illumination.
