Abstract
The utility model discloses an LED fluorescent lamp illumination system controlled through infrared induction. The LED fluorescent lamp illumination system is characterized in that the LED fluorescent lamp illumination system comprises an infrared probe, an IC amplifier, a PWM dimming power supply and an LED fluorescent lamp, wherein the infrared probe is connected with the IC amplifier; the IC amplifier is connected with the PWM dimming power supply; and the PWM dimming power supply is connected with the LED fluorescent lamp. The LED fluorescent lamp illumination system controlled through infrared induction has the advantage that the PWM dimming power supply can reduce electric currents when the infrared probe does not detect the movement of a human body or object, and therefore the brightness of the LED fluorescent lamp becomes weak and the power-saving mode is switched on.
Description
Technical field
The utility model relates to a kind of illuminator, specifically is a kind of LED fluorescent lamp lighting system of infrared induction control.
Background technology
The LED fluorescent lamp has multiple advantage: (1) is energy-efficient, and with same brightness relatively, the energy consumption of LED day lamp is lower than 1/10 of ordinary incandescent lamp; (2) extra long life, can reach 50,000 hours useful life;
(3) health, it is few with infrared ray to contain ultraviolet ray in the healthy light of light, and the generation radiation is few; (4) environmental protection, harmful elements such as not mercurous and xenon are beneficial to recovery; (5) vision protection, DC driven, no stroboscopic; (6) coefficient of safety is high, and required voltage, electric current are less, and potential safety hazard is little, and in hazardous areas such as mining sites, so the LED fluorescent lamp is widely used in illuminator.
The utility model content
The purpose of the utility model provides a kind of LED fluorescent lamp lighting system of infrared induction control of power saving more.
The utility model has adopted following technical scheme:
The LED fluorescent lamp lighting system of infrared induction control; It is characterized in that, comprise infrared probe, IC amplifier, PWM light modulation power supply and LED fluorescent lamp, infrared probe connects the IC amplifier; The IC amplifier connects PWM light modulation power supply, and PWM light modulation power supply connects the LED fluorescent lamp.
Preferably, said IC amplifier mixes the application-specific integrated circuit amplifier for the COMS digital-to-analogue.
The operation principle of the utility model is following:
After infrared probe detected human body or mobile object, signal passed to PWM light modulation power supply through the IC amplifier, and PWM increases electric current, and it is maximum that the brightness of LED fluorescent lamp reaches; Infrared probe does not detect human body or mobile object in setting-up time, and PWM light modulation power supply will reduce electric current, and the brightness of LED fluorescent lamp will weaken, and gets into battery saving mode.
