Detailed description of the invention
Be described further with regard to technical scheme of the present invention below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of lighting device for refrigerator.
With reference to Fig. 1, in an embodiment of the present invention, this lighting device for refrigerator comprises illuminating lamp 100, gate controlled switch 200, brightness detection module 300 and control module 400, and a drive end of described control module 400 is connected with described illuminating lamp 100; Described gate controlled switch 200 is connected with a trigger end of described control module 400; Described brightness detection module 300 is connected with an input of described control module 400; Wherein, illuminating lamp 100 is arranged at refrigerator inside, for providing illumination to refrigerator inside; Gate controlled switch 200, for when refrigerator door is opened, controls illuminating lamp 100 by control module 400 and lights; When refrigerator door is closed, control illuminating lamp 100 by control module 400 and control illuminating lamp 100 and extinguish; Brightness detection module 300 is for detecting the brightness of refrigerator inside environment, and output brightness signal; The luminance signal that control module 400 exports for receiving described brightness detection module 300, and export corresponding dim signal according to described luminance signal, to control the brightness of described illuminating lamp 100.Like this, when the light that available light or other illuminations provide can illuminate refrigerator inside, control module 300 controls illuminating lamp 100 and weakens luminosity, and the electricity that illuminating lamp 100 is consumed reduces, thus realizes energy-saving effect.
In the present embodiment, illuminating lamp 100 can adopt one or multiple LED composition, wherein when only there being a LED, by the dutycycle of control module 400 according to the corresponding adjustment output signal of the luminance signal detected, and the brightness size controlling described illuminating lamp 100 can be realized.And when adopting the compositions such as multiple LED, the brightness size realizing controlling illuminating lamp can also be lighted by the LED controlling varying number except the control mode of above-mentioned dutycycle.
In the present embodiment, above-mentioned brightness detection module 300 can be the detecting element that can detect arbitrarily the brightness of refrigerator inside ambient light, such as light sensor, light sensor can detect the brightness of refrigerator inside environment, and exports control module 400 to after being converted to corresponding voltage signal.
Above-mentioned control module 400 can adopt PWM controller or chip microcontroller, the dim signal presetting dutycycle is exported by PWM controller or single-chip microcomputer, the value of this default dutycycle can be the arbitrary value between 0% to 100%, general value about 50%, like this in the moment of beating opening door body, can ensure that illuminating lamp 100 provides certain brightness of illumination to refrigerator inside.Then, when control module 400 receives the voltage signal of brightness detection module 300 output, according to voltage signal determination refrigerator inside ambient light situation.Like this, when refrigerator inside ambient light is more weak, the dutycycle of output signal tunes up by control module 400, and the light that illuminating lamp 100 is sent strengthens, and meets lighting demand; When refrigerator inside ambient light is stronger, the dutycycle of output signal is turned down by control module 400, and the light that illuminating lamp 100 is sent weakens, to save electric energy.So, when the light that available light or other illuminations provide can illuminate refrigerator inside, just carry out supplementary light without the need to illuminating lamp 100 with peak load work, now, according to the brightness of refrigerator inside surround lighting, the corresponding dutycycle by the signal controlling illuminating lamp 100 brightness is turned down, and the power that illuminating lamp 100 is consumed reduces, and then the electricity making illuminating lamp 100 consume reduces, and realizes energy-saving effect thus.
