Device for intelligent control of LED indoor illumination

Abstract

The invention discloses a device for the intelligent control of LED (light-emitting diode) indoor illumination. The device comprises a sensor, a sampling module, an A / D (analog-to-digital) converter, an intelligent processing chip, an internal memory, an input device, a display screen, a PWM (pulse-width modulation) signal generator, an LED drive circuit, an LED spotlight mode converting switch and an LED lamp system, wherein the LED lamp system comprises LED lamps with various colors and spotlight modules in different directions; the sensor is used for receiving the external signals and converting the signals into analog electrical signals; the sampling module is connected with the sensor and used for sampling the signals received by the sensor; the output terminal of the sampling module is connected with the A / D converter and used for transmitting the sampled optical signals to the A / D converter; the A / D converter is used for converting the received analog signals into digital signals and transmitting the converted signals to the intelligent micro-processor chip connected with the A / D converter; and the intelligent micro-processor chip is further connected with the sampling module and used for providing the clock frequency for the sampling module. Accordingly, the device is capable of automatically adjusting the light intensity, color and direction of the LED.

Description

technical field [0001] The invention relates to an indoor lighting control device, in particular to an LED indoor intelligent lighting control device. Background technique [0002] At present, lighting has gradually entered the LED era. Compared with energy-saving lamps and incandescent lamps that are still commonly used today, LEDs have the advantages of high electro-optical conversion efficiency, high luminous efficiency, long life, energy saving, safety, green environmental protection, and rich colors. LEDs can convert more than 99% of electrical energy into light energy, while energy-saving lamps can only reach 80%, and incandescent lamps are much lower; the light efficiency of LED high-brightness lighting can reach 80lm / W, while energy-saving lamps are only 60lm / W ; The service life of LED is theoretically as long as 50,000 hours, compared with only 10,000 hours for energy-saving lamps. With the development of science and technology, the light efficiency of LED is inc...

AI Technical Summary

Problems solved by technology

On the one hand, domestic LEDs have relatively large light attenuation; on the other hand, LEDs have a small luminous angle and a relatively single spectrum, so they are not suitable for direct use in indoor lighting places such as offices and residences.

However, there is no relevant report on the intelligent control of LED lighting
