Abstract
The utility model provides an LED lamp with light control function, which comprises a lamp housing and a circuit unit, wherein a printed circuit board is arranged inside the lamp housing; a plurality of LED lamp beads are arranged on the printed circuit board; the circuit unit mainly comprises a light-controlled switch module and a power source driving module, which are electrically connected with each other; and the power source driving module is electrically connected with the printed circuit board. Compared with the prior art, the light-controlled switch module that is arranged on the printed circuit board detects the ambient brightness in real time, and the light-controlled switch module determines whether to switch on the power source to turn on or off the LED lamp beads according to the ambient brightness, so as to achieve the effect of automatic light control of the LED buried lamp. The power source is cut off when the ambient light is bright; and the power source is switched on when the ambient light is dim. The utility model achieves the humanized design.
Description
Technical field
The utility model relates to the LED application, is meant a kind of LED light fixture especially.
Background technology
Advantages such as the LED lighting is energy-conservation owing to having, the life-span is long, environmental protection and light are soft are widely used.LED lighting of the prior art, the LED underground lamp tool that uses of public illumination particularly, usually adopt time-controlled mode to control its light on and off, but because weather constantly and irregularly changes, though be daytime sometimes, light is also darker, this moment is not owing to arrive setting-up time, LED underground lamp tool does not also work, and visible this LED underground lamp tool can't carry out switch according to the brightness of environment.Therefore, need a kind of LED underground lamp tool of exploitation badly according to the ambient brightness gauge tap.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming that LED underground lamp tool of the prior art can't carry out switch according to ambient brightness, and a kind of light control functionality LED light fixture is provided.
The utility model adopts following technical scheme:
A kind of light control functionality LED light fixture includes lamp housing and circuit unit, is provided with printed circuit board (PCB) in this lamp housing, and this printed circuit board (PCB) is provided with some LED lamp pearls; This circuit unit mainly comprises the light-operated switch module and the electric power driving module of mutual electrical connection, and this electric power driving module is electrically connected on described printed circuit board (PCB).
Further, the rear portion of described lamp housing is equiped with the heat dissipation metal device.
Further, the front end periphery of described lamp housing is arranged with the surface metal frame.
Further, described LED lamp pearl is the large-power LED light bead that is not less than 1W.
By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of light control functionality LED light fixture of the present utility model has following beneficial effect:
At first, the utility model comes real-time testing environment brightness by be provided with the light-operated switch module on circuit unit, whether decision connects power supply to open or to close LED lamp pearl according to ambient brightness light-operated switch module, realize the automatic light-operated control of LED underground lamp tool, when ambient brightness is brighter, cut off the electricity supply, when ambient brightness is dark, connect power supply, very hommization of design;
Secondly, the rear portion of lamp housing is equiped with the heat dissipation metal device, and the heat that makes LED lamp pearl produce leaves immediately, prolongs the service life of LED underground lamp tool;
The 3rd, the front end periphery of lamp housing is arranged with the surface metal frame, has attractive in appearance, anticorrosive and the compressive resistance effect, prolongs the service life of LED underground lamp tool;
The 4th, LED lamp pearl is the large-power LED light bead that is not less than 1W, and luminous flexibility is good, light is even, angle is good, no zebra-stripe phenomenon.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model specific embodiment;
Fig. 2 is the plan structure schematic diagram of the utility model specific embodiment.
The specific embodiment
Below the utility model will be further described by the specific embodiment.
See figures.1.and.2, a kind of light control functionality LED light fixture of the present utility model, include lamp housing 10 and circuit unit 20, be provided with printed circuit board (PCB) 11 in the lamp housing 10, printed circuit board (PCB) 11 is provided with the LED lamp pearl 12 of three 1W, the rear portion of lamp housing 10 is equiped with heat dissipation metal device 30, and the front end periphery of lamp housing 10 is arranged with surface metal frame 40.
See figures.1.and.2, circuit unit 20 mainly comprises the light-operated switch module 21 and the electric power driving module 22 of mutual electrical connection, and electric power driving module 22 is electrically connected on printed circuit board (PCB) 11.
A kind of light control functionality LED light fixture of the present utility model in use, light-operated switch module 21 connects civil powers, and the 21 real-time testing environment brightness of light-operated switch module are when light-operated switch module 21 detects ambient brightness when brighter, light-operated switch module 21 is cut off the electricity supply, and LED lamp pearl 12 does not work; When light-operated switch module 21 detects ambient brightness when dark, light-operated switch module 21 is connected power supply, luminous by electric power driving module 22 driving LED lamp pearls 12, thereby realize the automatic light-operated control of LED underground lamp tool, no matter the time how, as long as ambient brightness meets the demands, light-operated switch module 21 will switch on or off power supply automatically.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
