Description
Technical field
The utility model relates to a kind of with the LED lighting of human body sensing as control mode.
Background technology
Existing LED light fixture does not normally possess the light regulatory function.This makes that the range of application of LED light fixture is very narrow, uses also not very convenient.In addition, the LED light fixture generally only is provided with a mechanical button as shift knob, and what have perhaps adopts electrostatic inductor to control as switch.But after having the light regulatory function on the LED light fixture, simple above-mentioned button or control mode can not satisfy the operation requirement.Though can be through increasing such as the usefulness as the light adjusting such as rotary switch, traditional switch or knob much still belong to mechanical component, except the big influence of volume is attractive in appearance, also are easy to break down.So need improve to existing LED light fixture.
The utility model content
The purpose of the utility model provides a kind of LED light fixture that carries out light control with the noncontact mode.
For achieving the above object, the technical scheme below the utility model has been taked:
A kind of Dimmable LED light fixture of human body induction control comprises the LED illumination head, and the LED illuminator is installed in the LED illumination head; Especially, also comprise human body sensing emitter, human body sensing receiving system, central processing unit, switching mode control circuit, light-modulating mode control circuit, led drive circuit and power circuit; Human body sensing emitter, human body sensing receiving system are communicated with central processing unit respectively; The switching mode control circuit is communicated with central processing unit and led drive circuit respectively; The light-modulating mode control circuit is communicated with central processing unit and led drive circuit respectively; Led drive circuit is communicated with the LED illuminator; Power circuit is communicated with central processing unit and led drive circuit.
Wherein:
The human body sensing emitter is used to send infrared light etc. can be by the signal of human hands reflection.
The human body sensing receiving system is used in its effective investigative range surveying the signal that infrared light etc. is sent by the human body sensing emitter, and the signal strength signal intensity that is received is fed back to central processing unit.Such contactless humanbody sensing receiving system can be infrared human body sensor or microwave human body sensor.
Central processing unit is judged and corresponding gauge tap mode control circuit and light-modulating mode control circuit signal behind the signal that receives from the human body sensing receiving system.Thereby realize such as the On/Off light fixture functions such as raising/reduction brightness.
The switching mode control circuit is realized the On/Off action of light fixture through the parameter that changes led drive circuit under the control of central processing unit.
The light-modulating mode control circuit is realized the raising/reduction brightness action of light fixture through the parameter that changes led drive circuit under the control of central processing unit.
Led drive circuit is the power-switching circuit between power circuit and the LED illuminator, and it provides power parameter adjustable supply of electric power for the LED illuminator.
Power circuit provides corresponding work electricity consumption to all power devices of this light fixture.Its inside can be provided with the voltage stabilizer, to adapt to various input power supplys.As: electric main input or low-voltage direct input.
The operation principle of the utility model is following: when the hand of human body and the position between the human body sensing receiving system change, corresponding variation will take place in the intensity by the signals such as infrared light of human hands reflection that the human body sensing receiving system can receive.Central processing unit changes according to received signal makes actions such as switch control, brightness adjustment control with corresponding, so make this light fixture to be controlled according to the contactless action of human body.
LED illuminator in the utility model preferably adopts flat-plate light source.
The utility model carries out light with non-contacting human body sensing mode and regulates operation, has advantages such as easy to use, elegant in appearance, can a kind of brand-new experience be provided for the user, promotes user's life taste.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit theory calcspar of the utility model embodiment.
Description of reference numerals: 1-base; The 2-arm; The 3-LED illumination head; The 4-power supply adaptor.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
Be example with the LED desk lamp, as shown in Figure 1, the LED desk lamp is made up of the base that is installed together successively 1, arm 2 and LED illumination head 3.The LED illuminator is installed in LED illumination head 3.Also be provided with independently power supply adaptor 4 in addition.
Human body sensing emitter and the human body sensing receiving system of using infrared principles are installed on base 1, central processing unit, switching mode control circuit, light-modulating mode control circuit and led drive circuit (not shown) are arranged in the base set inside.As shown in Figure 2, human body sensing emitter, human body sensing receiving system are communicated with central processing unit respectively; The switching mode control circuit is communicated with central processing unit and led drive circuit respectively; The light-modulating mode control circuit is communicated with central processing unit and led drive circuit respectively; Led drive circuit is communicated with the LED illuminator.Power supply adaptor 4 inside are power circuit, and power circuit is communicated with central processing unit and led drive circuit.
During use, hand right-to-left above the human body sensing receiving system skims over, and then central processing unit is made the judgement of opening the LED illuminator, and desk lamp is opened; When hand skims over above the human body sensing receiving system from left to right once more, then central processing unit makes the judgement of cutting out the LED illuminator, and desk lamp is closed.When desk lamp was in opening, hand is bottom-up motion above the human body sensing receiving system, and then central processing unit is made the judgement that improves brightness, and desk lamp becomes light; On the contrary, hand is motion from up to down above the human body sensing receiving system, and then central processing unit is made the judgement that reduces brightness, desk lamp deepening.
The preferred embodiments that is merely the utility model of this specification lists, the equivalent technologies conversion of being done under all operation principle and thinkings at the utility model all is regarded as the protection domain of the utility model.
