A kind of Novel control electro-optical device for picture signal LED

Technical field

The utility model relates to a kind of LED, particularly a kind of Novel control electro-optical device for picture signal LED.

Background technology

The micropolis of China is after 9 of nights, and big and medium-sized cities are after 12 of midnights, almost empty on road, even if the busy city that Beijing, Shanghai and Guangzhou are such, after 2:00 AM, there will be the situation of the low magnitude of traffic flow, that is, now pedestrian or the vehicle on road is all less. But even when this low magnitude of traffic flow, public place LED illumination keeps the brightness of former illumination, not to regulate and control brightness of illumination as required, waste power supply in vain. The detection range of existing infrared induction, Doppler's induction (radar induction) is near, is not suitable for requiring the detection range public place LED with identifying static human body far away.

Chinese patent literature CN 204127795U disclosed a kind of adjustable spectroscopic light source for Color Image Acquisition on 01 28th, 2015, it is characterized in that: multispectral lighting unit composes in parallel full spectral luminescence unit by the LED light emitting diode of 7 different wavelength range, the wherein LED of 7 LED light emitting diode employing different wave lengths, each LED light emitting diode is connected respectively to 7 amplifier-drivers, be connected with DSP processing module again, DSP processing module is connected with spectra collection feedback unit circuit, Spectral beam combining control and driver element circuit comprise LED interface, amplifier-driver, DSP processing module, spectra collection feedback unit interface, USB interface of computer, power supply, its a set of light source just can be realized multiple different spectral signatures composition, is adapted to all objects of different lighting demands.
