Description

Light-operated LED driving system
Technical Field
The invention relates to the technical field of LED driving, in particular to a light-operated LED driving system.
Background
LEDs are characteristic sensitive semiconductor devices and have negative temperature characteristics, so they need to be stable in operation and protected during application, resulting in the concept of a driver. The requirements of the LED device on a driving power supply are nearly strict, and the LED can be directly connected with 220V alternating current commercial power unlike a common incandescent bulb. An LED Driver refers to a power supply adjustment electronic device that drives an LED to emit light or an LED module assembly to normally operate. Due to the conduction characteristic of the PN junction of the LED, the voltage and current variation range of a power supply which can be adapted to the PN junction of the LED is very narrow, and the LED cannot be lightened or the luminous efficiency is seriously reduced or the service life is shortened or even a chip is burnt down if the PN junction of the LED deviates a little. Both the current industrial frequency power supply and the common battery power supply are not suitable for directly supplying the LEDs, and the LED driver is the electronic group capable of driving the LEDs to work under the optimal voltage or current state.
Since the LED is applied in almost all fields of electronics, and the variations of the light intensity, light color, on-off control, etc. are almost unpredictable, the LED driver becomes almost a one-to-one servo device, so that the family members of the device become all-round. The simplest LED driver (if it can be so called) may be one or several series-parallel rc elements shunting a voltage division in the loop, which does not become a separate product at all. For more general commercial applications requiring stable constant current and voltage output, a series of system solutions with accurate power regulation capability are formed. The realization of these solutions usually requires a relatively complex circuit design, and the core of the realization is the integrated application of the LED driving IC. Different support circuits are arranged on the periphery of the LED drive IC, so that different LED application solutions are constructed, namely backlight of a small-sized mobile phone display screen and key light drive, and a large-sized high-power LED street lamp, a large-sized outdoor LED display screen and the like.
However, the existing light-operated driver of the LED generally only controls through light sensation, and the control mode is single, so that unnecessary resource waste is generated when the driver is used, and the problem of inconvenient use is caused.
