Description
Technical Field
The utility model relates to a mixing of colors control technical field of adjusting luminance especially relates to an intelligent light-adjusting mixing of colors temperature circuit.
Background
The smart dimming power supply on the market at present has the following types:
1. the traditional dimming power supply supporting phase-cut dimming does not support a mobile phone and remote control;
2. the PWM dimming power supply supports a mobile phone and a remote control, but does not support a phase-cut dimmer and wall switch dimming;
3. and the dimming power supply supports 0-10V analog dimming. Traditional switches and phase cut dimmers are not supported;
4. the phase-cut dimming is supported, the phase-cut dimmer is used for directly supplying power to a rear-stage dimming circuit after chopping, the rear-stage circuit detects the conduction angle of the silicon controlled rectifier, the wireless connection module or the microcontroller converts the detected conduction angle signal into a PWM dimming signal with a corresponding duty ratio to supply to the power supply control IC, and then the output power of the control power supply realizes dimming. However, the disadvantages of this method are: when the conduction angle is lower than a certain value, the rear-stage power supply works unstably, and the dimming flicker even can not be adjusted. A remedy method is that when the conduction angle is lower than a certain value, the phase-cut dimming mode is entered, the PWM dimming circuit is closed, and when the conduction angle is larger than the certain value, the PWM dimming can be entered. When the physical position of the dimmer is below this value, the handset or other remote control terminal is in any case not controllable. The use experience is poor.
In summary, existing dimming power supplies are limited in use to the type of dimming supported by the dimmer and the load fixture. Especially, when the intelligent dimming lamp is refitted on a line provided with a traditional switch or a traditional phase-cut dimmer, the switch or the dimmer needs to be dismantled or refitted, otherwise, the normal work of a dimming system is influenced. The existing schemes which can use phase-cut dimming are not completely compatible, and cannot be adjusted in a full range and completely independently.
