Abstract

An energy saving type of light emitting diode lamp is disclosed. In such a manner, the human body sensor may be used to detect existence of the human body. Thus, the LED lamp is disposed at a low illuminance state normally, and may be converted into a high illuminance state when the human body approaches. In addition, the light sensor may be used to detect the environmental illuminance. Thus, when the environmental illuminance is insufficient, the light source is fully opened or half opened, and when the environmental illuminance is sufficient, the light source is closed. In such a manner, the LED lamp may be operated by a high power with a large current during a short time, so that the LED lamp consumes less electricity, has a long lifetime, and saves energy highly.
