What about the lot Electric current can be built using infrared LED?

General IR chip processing of the infrared LED can withstand only 4~500mA,preferably at added up to current-limiting resistance.the ir led be electric current under 300 mA in General. VF about in 1.7V the infrared emission tube almost reached the power of peak transmit.under the condition of ir chip with 300mA. All of ir led are subject to the most stringent testing and checking procedures with DC current 50mA.

In instantaneous the current of infrared led can reach the 800mA,then if you use poor infrared led can cause burning or transmit power attenuation fast, the infrared emission tube can withstand the instantaneous current of 1000mA,
but in the current led market, some ir led can withstand the instantaneous current of 1000mA,The solution can solve that problem. of course, the shortcomings of design is battery consumption faster.
