Abstract
The utility model discloses an automatic brightness regulating and controlling system of a lighting lamp of a range hood. The automatic brightness regulating and controlling system comprises a range hood main body, a lighting lamp, an illuminance transducer and a control unit, wherein the lighting lamp is arranged on the range hood main body; both the illuminance transducer and the control unit are electrically connected to an external power source; the illuminance transducer is used for detecting a light ray intensity signal of a kitchen and transmitting the light ray intensity signal to the control unit; and the control unit is used for controlling the brightness regulation of the lighting lamp, so that a perception requirement of eyes on light rays is met.
Description
Technical field
The utility model relates to range hood illuminating lamp field, relates in particular to a kind of range hood lighting brightness automatic regulating system.
Background technology
Range hood in the market is culinary cuisine for ease, all is furnished with illuminating lamp, but these illuminating lamps do not have brightness control function, can not adapt to the brightness demand under the multiple kitchen environment.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of range hood lighting brightness automatic regulating system, and this regulator control system can have more the brightness of the adjusting illuminating lamp of hommization, well satisfies the perception requirement of human eye to light.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of range hood lighting brightness automatic regulating system; Comprise range hood main body and illuminating lamp provided thereon; Be provided with an illuminance transducer and a control unit; Said illuminance transducer and said control unit all are electrically connected on external power source, and said illuminance transducer is in order to the light intensity signal that detects the kitchen and be messaging in said control unit, and said control unit is controlled said lighting brightness and regulated; Promptly adjust the supply power voltage of said illuminating lamp, to satisfy the perception requirement of human eye to light.
As the further improvement of the utility model, the measuring range of said illuminance transducer and human eye are complementary to the visibility of light.The operation principle of said illuminance transducer is well known to those skilled in the art, and does not do detailed description at this.
As the further improvement of the utility model, said illuminating lamp is a kind of in incandescent lamp and the LED lamp.
As the further improvement of the utility model, said control unit adopts PWM to regulate output control.
The beneficial effect of the utility model is: through adopting the illuminance transducer that light visibility is complementary with human eye; When range hood is opened illumination functions; Illuminance transducer can detect the light intensity signal of kitchen environment in real time and be messaging in said control unit; Signal is after the control unit collection analysis is handled, and lighting brightness is regulated in control unit output automatically, to satisfy the perception requirement of human eye to light.

Fig. 3 is another structural representation of the utility model.
Embodiment
Embodiment to the range hood lighting brightness automatic regulating system of the utility model is elaborated with reference to the accompanying drawings.
A kind of range hood lighting brightness automatic regulating system of the utility model; A kind of range hood lighting brightness automatic regulating system; Comprise range hood main body and illuminating lamp 1 provided thereon, be provided with an illuminance transducer 2 and a control unit 3, said illuminance transducer and said control unit all are electrically connected on external power source; Said illuminance transducer is in order to the light intensity signal that detects the kitchen and be messaging in said control unit; Said control unit is controlled said lighting brightness and is regulated, and promptly adjusts the supply power voltage of said illuminating lamp, to satisfy the perception requirement of human eye to light.
In the present embodiment, said illuminance transducer is to be located at and to break away from a kind of installment state in said range hood main body; The measuring range of said illuminance transducer and human eye are complementary to the visibility of light.
In the utility model; The operation principle of range hood lighting brightness automatic regulating system is: 1) at first utilize said illuminance transducer 3 to detect the light intensity signal of kitchen environment in real time, and this signal is transferred to the input port (being the A port) of said control unit 4;
2) when said range hood is not opened illumination functions, the output of the output port of said control unit 4 (being the B port) no signal, in the present embodiment; Said control unit adopts PWM to regulate output control; Triode Q11 does not work, said illuminating lamp 2 no-voltages power supply, and illuminating lamp 2 is not lighted; In the present embodiment, said illuminating lamp is a kind of in incandescent lamp and the LED lamp; When said range hood was opened illumination functions, said control unit 4 was gathered the data value of A port, and carries out analyzing and processing, then via B port output pwm pulse signal;
3) modulate via the conducting state of pwm signal control triode Q11 after, said control unit 4 control illuminating lamps 2 are lighted work;
4) variable quantity of said illuminance transducer 3 induction kitchen environment light intensity signals; And feed back to said control unit 4 in real time through the A port; Control unit 4 is adjusted the frequency or the duty ratio of B port output pwm signal, the time value of just adjusting the triode conducting and ending with signal processing analysis; Thereby the supply power voltage of adjustment illuminating lamp 2 promptly reaches the purpose of regulating lighting brightness.
