USEHOLD HOME LED

Of high-power white LED luminous efficiency were studied, the temperature and current draw of the LED luminous efficiency: With the temperature increasing, the potential well in the composite risk of lower radiation, thereby reducing the light-emitting efficiency; current increased, so that more non-equilibrium carriers through the barrier, reducing the efficiency of the LED. LED work, the working temperature is too high or too much current will have a clear light failure: If the LED chip operating temperature over the load temperature, This will enable the LED luminous efficiency of the rapid reduction of light have a clear failure, and cause permanent damage to the LED; If the LED chip more than the operating current of saturated current, LED luminous efficiency will also reduce the rapid, resulting in a clear light failure . and LED temperature and can carry a certain relationship between the saturation current, good heat dissipation LED device that can reduce some of the relative temperature, saturation current can be greater, LED will be relatively larger in the current work.
