ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an infrared sensitive electric controlled lamp seat, and especially to a lamp seat which can be installed to an original lamp seat, while in a range, it can detect the moving of a people and then control the illumination of a bulb.
BACKGROUND OF THE INVENTION
Light has become a necessary power in daily life. By the invention of bulbs, fluorescent lamp, and other illuminating devices. Therefore, peoples may work at any time. Therefore, bulbs, fluorescent lamps, and other illuminating devices are used anywhere. For convenience, often peoples do not turn off the lamp as they leave from a room. Even nobody is in the room, the lamp still lights up. Therefore, power waste is formed.
Moreover, the switches of bulbs, fluorescent lamps, and other illumination devices are installed at corners of walls. In the night, people can not search for the switch in the dark. This is not matched the use of the illuminating device.
Therefore, there is an eager demand of a novel designed in which in a range, it can detect the moving of a people and then control the illumination of a bulb.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an infrared sensitive electric controlled lamp seat for controlling the illumination of a bulb automatically. The infrared sensitive electric controlled lamp seat includes a lamp seat and an electric controlled device. The lamp seat is a power transferring case having a U shape cone-like shape, and the upper end thereof is installed with a conductive stud, while the lower end thereof is installed with a cone net bulb fixing case. The bottom of the bulb fixing case is installed with a conductive stud for locking the bulb. The electric controlled device is a circuit board. The center of the bottom is installed with an infrared sensing head. The circuit board is firmly secured to the bulb fixing case so that the infrared sensing head is exactly protected in the net case. The power transferring case serves to cover the upper portion of the bulb fixing case. Therefore, a infrared sensitive electric controlled lamp seat is formed. Therefore, the present invention can be installed to another lamp seat for inserting a bulb to automatically sense and control the illumination of a bulb.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when reading in conjunction with the appended drawing.
