Fig. 2 is the structural representation of the adjustable light fixture of the utility model brightness;
Fig. 3 is the structural representation of incandescent lamp bulb and LED light source in the adjustable light fixture of the utility model brightness;
Fig. 4 is the circuit diagram of the adjustable light fixture of the utility model brightness.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the light fixture that described brightness is adjustable comprises gauge tap 1 and light fitting body;
Described light fitting body comprises pedestal 2, incandescent lamp bulb 3 and the LED light source 4 be located on described pedestal 2, for sealing the lamp housing 5 of described incandescent lamp bulb 3 and LED light source 4, described incandescent lamp bulb 3 is located in the middle part of described pedestal 2; Described incandescent lamp bulb 3 is in parallel with LED light source 4, and is electrically connected with described gauge tap 1 respectively, and described gauge tap 1 controls the open and-shut mode of described incandescent lamp bulb 3 and LED light source 4.
It should be noted that, by increasing LED light source 4 on original pedestal 2, incandescent lamp bulb 3 and LED light source 4 being worked simultaneously.During work, controlled by the duty of gauge tap 1 pair of incandescent lamp bulb 3 and LED light source 4, realization only have incandescent lamp bulb 3 bright, only have that LED light source 4 is bright, incandescent lamp bulb 3 and LED light source 4 simultaneously bright, incandescent lamp bulb 3 go out with LED light source 4 simultaneously, Deng four kinds of luminances, thus ensure, on the basis not changing original incandescent lamp bulb 3 structure, to realize the adjustable of brightness.
As shown in Figure 3, described LED light source 4 equidistant arrangement is located on described pedestal 2, forms endless loop; Described incandescent lamp bulb 3 is located in described endless loop.
It should be noted that, incandescent lamp bulb 3 is located in the middle part of described pedestal 2, and described LED light source 4 is for being at least four, and equidistant arrangement also forms endless loop, and light source can be made balancedly to be distributed in all directions, and light source is irradiated to greatest extent, and light is more stable.
More preferably, the light fixture that described brightness is adjustable also comprises the sheet glass 6 be located at below described LED light source 4, and sheet glass 6 pairs of LED light sources 4 effectively seal, and realize the effective refraction to LED light source 4.
When LED light source 4 is to external exposure, first through sheet glass 6, carrying out first time reflects process, then through lamp housing 5, carries out second time and reflects process.LED light source 4, after twice refraction, makes light can not the eyes of direct projection people, uses more comfortable.
More preferably, the thickness of described sheet glass 6 is 3mm, is easy to processing.
More preferably, described gauge tap 1 is rotary switch, is controlled the open and-shut mode of described incandescent lamp bulb and LED light source by the gear of described rotary switch respectively.
