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.
Claims7
An energy saving type of light emitting diode lamp, comprising:
- a human body sensor,
- multiple light emitting diode members,
- a light sensor,
- a control circuit,
- a time regulating switch,
- a lamp face plate,
- a lamp housing, and
- a bulb copper head, wherein;
- the lamp face plate is mounted on the lamp housing,
- the human body sensor and the multiple light emitting diode members are placed in the lamp face plate,
- the light sensor is mounted on one side of the lamp face plate,
- the control circuit including the time regulating switch is placed in the lamp housing,
- the electric power terminal of the lamp housing is the bulb, copper head, and
- the bulb copper head is mounted on a socket of a conventional illumination filament type bulb;
- and wherein
- the human body sensor is used to detect existence of the human body, so that when no one has passed the lamp for a predefined period of time, the lamp uses a low power with brightness that is less than half of full brightness, and when a human body triggers the human body sensor, the lamp uses a high power with full brightness.
