Description
Technical field
This utility model relates to a kind of illuminator and drives power supply, refers in particular to a kind of LED Intelligent electrodeless dimming power source.
Background technology
The dimming mode of existing LED power has three kinds:
1, linearity light adjusting: power supply chip has individual brightness adjustment control pin, connect adjustable resistance to ground, regulate the resistance of this potentiometer, change the voltage of this brightness adjustment control pin, the PWM pulsewidth making the output driving MOS of PWM control chip changes and reaches to regulate the electric current of LED, obtain dimming effect, such as desk lamp；
2, PWM light modulation: this pwm signal is produced by other IC, reaches to dim purpose, such as remote control by regulating the voltage of the brightness adjustment control pin that the pulsewidth dimming PWM signal controls power supply chip；
3, phase dimming: be most commonly that controllable silicon light modulation, reaches to dim purpose by the input voltage phase angle adjusting input LED power module.But silicon controlled dimming mode belongs to forward position formula light modulation, its power supply architecture is more complicated, and stability is the most weak, easily produces noise, and the suitability is the most limited.
But no matter which kind of dims, and is required for artificially going regulation and control, and cannot be automatically performed.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, it is provided that a kind of LED Intelligent electrodeless dimming power source.
The purpose of this utility model is achieved in that a kind of LED Intelligent electrodeless dimming power source, and it includes EMC and rectification module, damping module, holding loop current module, main changed power module and output constant voltage and current limiting module；Power supply input EMC and rectification module, the output of EMC and rectification module connects damping module, damping module output connection maintains the reflux for current module, maintain the reflux for the current module output main changed power module of connection, the output of main changed power module is connected to export constant voltage and current limiting module, and the output last out-put supply of constant voltage and current limiting module drives LED；
In said structure, being connected MCU module between damping module with main changed power module, described MCU module is also connected with memory module.
The beneficial effects of the utility model are to use phase dimming mode, and do not use controllable silicon light modulation, but by damping module, keep loop current module coordinate main changed power module and output constant voltage and current limiting module dim, complete machine when the phase angle of 30%, the rate of complete machine > 80%.Coordinate electronic light modulator can realize light modulation, flicker free during whole, noiselessness, this utility model obtains the regulation data of conventional main changed power module also by MCU module and stores in a storage module, call for user and consult, it is also possible to automatically perform dimmer procedure by conventional data.
