1. Field of the Invention
The present invention relates generally to a lamp tube, and more particularly to a Passive Infrared sensor (PIR) inductive LED lamp tube.
2. Description of Related Art
Lamps are widely applied to lightings of urban roads, courtyards, corridors, garages, offices and public occasions, etc, for the benefit of the users. The commonly used lamps include: tungsten lamps, fluorescent lamps and LED lamps, of which LED lamps are most commonly used due to the advantages such as high efficiency, safety, energy-saving, environmental protection, long service life and quick response.
LED lamp tube is a common LED lighting that permits to control the on/off state of LED lamp bulbs by the switch, but it is inconveniently operated unsuitable for auto-control occasions.
The objective of the present invention is to provide a PIR inductive LED lamp tube that can be conveniently operated suitable for auto-control occasions.
The present invention can be implemented through the following technology schemes: a PIR inductive LED lamp tube, which comprises a lamp shade, lamp holder, LED lamp and lamp tube, of which the lamp holder is set at both ends of the lamp tube, the lamp shade is set onto the lamp tube to cover said LED lamp; it also comprises a PIR sensor, which is set onto said lamp shade.
Said lamp tube is an aluminum alloy radiator.
Radiating fin is set onto the external wall of said aluminum alloy radiator.
Said lamp shade is a semi-spherical tube.
Said lamp shade is a PVC tube shield.
The efficacies of present invention include: said PIR inductive LED lamp tube comprises: a lamp shade, lamp holder, LED lamp and lamp tube, of which the lamp holder is set at both ends of the lamp tube, the lamp shade is set onto the lamp tube to cover said LED lamp; it also comprises a PIR sensor, which is set onto said lamp shade. When the temperature of human body is sensed by PIR sensor, LED lamp is highlighted; otherwise LED lamp is extinguished, thus realizing convenient auto-control and utilization.
The following is a detailed description of the present invention based on the attached drawings:
Referring to
The operating principle of said PIR inductive LED lamp tube of the present invention is that: when the temperature of human body is sensed by PIR sensor 4, LED lamp is highlighted; otherwise LED lamp is extinguished, thus realizing convenient auto-control. If switches are used collaboratively, it can be used more flexibly and conveniently in auto-control occasions.
The above is a detailed description of the technical features of the utility model based on a typical preferred embodiment. However, it should be appreciated that the present invention is capable of a variety of embodiments and various modifications by those skilled in the art, and all such equivalent variations or changes shall be embraced within the scope of the following claims.
