Abstract
The utility model discloses a brightness-adjustable energy-saving LED driving power supply comprising a power supply, a single-chip microcomputer, a light-modulation control chip, a freewheeling loop device, an LED and a light sensitive detector, wherein the light-modulation control chip is connected with one end of the single-chip microcomputer and one end of the freewheeling loop device. The other end of the single-chip microcomputer is connected with the power supply. The other end of the freewheeling loop device is connected with the LED. The light sensitive detector is provided with a photosensitive triode. Brightness of a surface of an irradiated object can be inducted and output current can be automatically adjusted by the photosensitive triode. When the irradiated object is changed or an irradiation distance is reduced, the brightness of the surface of the irradiated object is adjusted, so that the brightness is not dazzling, eyes can clearly see the object and energy is saved.
Description
Technical field
The utility model relates to a kind of energy-saving LED driving power of adjustable brightness.
Background technology
LED is as new type light source, and it has energy-saving and environmental protection, characteristics of high efficiency, just is being applied to every field and is being extensive use of, and various led drive circuits also occurred thereupon.At present in the place of low-voltage, adopt the DC-DC chopper circuit to come driving LED basically, it has, and power consumption is little, efficient is high, reliable and stable, advantage such as the unit power volume is little, in light weight; But the DC-DC chopper circuit can't be realized the continuous light tuning function to LED, has brought very big inconvenience and energy consumption height to the user.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy-saving LED driving power of adjustable brightness of efficient simple, energy savings.
For addressing the above problem, the utility model adopts following technical scheme: a kind of energy-saving LED driving power of adjustable brightness, comprise power supply, single-chip microcomputer, brightness adjustment control chip, continuous current circuit device, LED and light-sensitive detector, described brightness adjustment control chip connects an end of single-chip microcomputer and an end of continuous current circuit device, the other end of described single-chip microcomputer connects power supply, the other end LED of continuous current circuit device, described light-sensitive detector is provided with phototriode.
As optimized technical scheme, described light-sensitive detector links to each other with single-chip microcomputer.
The beneficial effect of the energy-saving LED driving power of the adjustable brightness of the utility model is: the brightness that can be used for responding to the photographed object surface by phototriode, automatically regulate the electric current of output, when photographed object changes or irradiation distance when dwindling, regulate the brightness on photographed object surface, thereby it is dazzling and can see object clearly to reach eyes, more energy-conservation yet.
Description of drawings
Fig. 1 is the circuit block diagram of the energy-saving LED driving power of the adjustable brightness of the utility model.
Embodiment
See also shown in Figure 1, the energy-saving LED driving power of a kind of adjustable brightness of the present utility model, comprise power supply, single-chip microcomputer, brightness adjustment control chip, continuous current circuit device, LED and light-sensitive detector, described brightness adjustment control chip connects an end of single-chip microcomputer and an end of continuous current circuit device, the other end of described single-chip microcomputer connects power supply, the other end LED of continuous current circuit device, described light-sensitive detector links to each other with single-chip microcomputer.Described light-sensitive detector is provided with phototriode.Can respond to the brightness of indoor environment by light-sensitive detector, regulate the brightness of LED, thereby realize control, reach the purpose of energy savings LED brightness by the brightness adjustment control chip.
The beneficial effect of the energy-saving LED driving power of the adjustable brightness of the utility model is: the brightness that is used for responding to the photographed object surface by phototriode, automatically regulate the electric current of output, when photographed object changes or irradiation distance when dwindling, regulate the brightness on photographed object surface, thereby it is dazzling and can see object clearly to reach eyes, more energy-conservation yet.
The above only is an embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
