At present,there are some solar lawn lamp 30 super bright white LED,input power of 2Wabove,in this case,if the if the trichromatic color high-performance energy-savinglamp,the price is only 1/10 of the LED,luminous flux for four times the original,now has been developed for low voltage DC 2~10W three Color color high-performanceenergy-saving lamp,life can be up to 6000 hours.Based on the above analysis,webelieve that the brightness adjustment,with the frequent switching function of 1W belowsmall power solar lawn lamp,the general should be made with LED as the light source.But when using super bright white LED particular attention to lumen maintenance rate,otherwise easily lead to accidents.For larger power solar lawn lamp currently usedtrichromatic color high-performance energy-saving lamp is reasonable.The emphasis hereis,the above conclusion is only the current analysis,when the led to improve thetechnical level,the decline in prices.For solar garden lights,from the reliability,performance to price ratio,temperature,and light emitting efficiency of several aspects of the comprehensive consideration,webelieve that the ideal light source should be currently trichromatic color high-performance energy-saving lamp 5 LED use pay attention to Item 1)due to the operatingvoltage of the LED change 0.1V,current may change 20mA around.For safety,underordinary circumstances the use current limiting resistor in series,great energy loss isobviously not suitable for solar lawn lamp and LED brightness varies with the workingvoltage.The boost circuit is a good way,can also be used for simple constant currentcircuit,a total of Set to automatic current limit,otherwise it will damage the LEDs.2)led by general peak current 50~100mA.About reverse voltage 6V,pay attention to donot exceed this limit,especially in solar battery reverse connection or battery no-load,boost circuit,peak voltage is too high is can exceed this limit,damage the LEDs.3)led temperature characteristic is not good,the temperature rise of 5 DEG C,fluxdeclined 3%,use in the summer should pay attention to.4)operating voltage largediscreteness,the same types of,the same batch of LED operating voltage have certaindifference,should not be used in tandem.To be used in parallel,should consider theuniform flow.5 super bright white LED color temperature 6400k~30000k.,low colortemperature of super bright white LED is not into the market,so super bright white LEDmanufacturing of solar lawn light penetration ability is poor,so we should payattention to in the design of optical.6)electrostatic of super bright white LEDinfluence greatly in installation to have anti-static facilities,workers should wearanti-static wrist.By electrostatic damage of super bright white LED was probably by theeye to look not to come out,but the service life will be shortened.
