An LED light emitting device includes a lamp housing, an LED light emitting component thermally attached to the lamp housing, a power source driver for providing electric energy for the LED light emitting component, and a temperature sensor attached to the lamp housing for sensing a surface temperature of an outer surface of the lamp housing. When the value of the surface temperature is smaller than a predetermined temperature value, the temperature sensor outputs a control signal to the power source driver to control the power source driver to supply a larger electric current to the LED light emitting component, and the LED light emitting component generates more heat to the lamp housing to increase the surface temperature thereof.
