Abstract
The utility model relates to an LED lamp control system, comprising a power module, a singlechip, a PWM module, PFM module, a synchronous control module, a drive module, and a wireless communication module. The system is provided with the PWM and PFM synchronous control module, thereby improving efficiency of the control system and using changes of pulse width and pulse frequency to adjust brightness, so that an LED lamp can be regulated in a linear manner in full brightness ranges.
Description
Technical field
The utility model relates to a kind of LED lamp control system.
Background technology
The LED illumination is the new generation of green light source that electric energy is converted into visible light, is described as the 3rd revolution on the illumination history, than traditional lightings such as incandescent lamp, fluorescent lamps, has characteristics such as energy-saving and environmental protection, the life-span is long, volume is little.Along with the increasing of country to LED illumination support policy, the LED illumination just progressively replaces traditional lighting.
In order to ensure the reliability and the brightness requirement that obtains expection of LED illuminator, controller is essential, and the outstanding controller of performance can allow the LED illuminator have best state and the long working life of trying one's best.Existing controller exists following defective:
(1) ability of burning voltage can't guarantee the current value by LED, is cost with the brightness that reduces LED often, controls by reducing the LED both end voltage.
(2) inefficiency needs to consume a large amount of electric energy, even surpasses the electric energy that the LED lamp consumes.
(3) adopt the simulation dimming mode that changes LED both end voltage or electric current to regulate the controller of brightness, because the brightness of LED is not linear relationship with electric current and voltage, can not realize average brightness regulation, and voltage and current often changes the life-span that can influence the LED lamp.
The utility model content
The purpose of this utility model is to provide a kind of LED lamp control system, solves the problems referred to above that existing LED lamp control system exists.
The technical scheme that realizes the utility model purpose is: the utility model comprises power module, the single-chip microcomputer that links to each other with power module outlet.
Also comprise the PWM module, the PWM module input links to each other with the single-chip microcomputer output with power module outlet respectively; PFM module, PFM module input link to each other with the single-chip microcomputer output with power module outlet respectively; Synchronization control module, the synchronization control module input links to each other with PFM module output with PWM module output; The driver module that links to each other with the synchronization control module output.
Also comprise the wireless communication module that is connected with the single-chip microcomputer input.
The utlity model has PWM and PFM synchronization control module, improved the efficient of control system, change with pulse duration and pulse frequency and regulate light, make the LED lamp to regulate in full brightness scope internal linear.
