Problems solved by technology

Although the thyristor dimming technology can meet the power supply of single fire wire, on the one hand, it cannot realize the transmission of digital signals, on the other hand, the standby power consumption of the control panel must be very low (microampere level), otherwise it will cause the LED lamps to flicker , so thyristor dimming is only suitable for dimming incandescent lamps, not for LED lamps

Embodiment Construction

[0023] according to figure 1 , the dimming system includes a dimming controller 1 and an LED lamp 24 . The dimming controller 1 is electrically connected to the LED lamp 2 through the user load power line, and the dimming controller 1 uses the power line 28 connected to its load output terminal to transmit digital control instructions to the LED lamps. The lamp 24 uses the sine wave of the AC220V AC power line on the load side to transmit a digital control signal at the zero crossing point, and the digital control signal can adopt a specific encoding method. The LED lamp 24 receives digital control instructions from the dimming controller 1 through the power line and executes corresponding actions, such as realizing state changes of brightness, color temperature and color, and single or any combination of lighting effects.

[0024] according to figure 2 The dimming controller 1 and the LED lamp 24 form a single circuit, and the power supply circuit 101 inside the dimming co...

Abstract

A dimming system is designed. The dimming system comprises a dimming controller and an LED lamp that are serially connected through a load power line, wherein the dimming controller is configured to send a digital control instruction to the LED lamp through the load power line, and a single-line type power supply loop is formed by the dimming controller and the LED lamp based on the load power line. The dimming system, under the conventional electrical wiring requirement, realizes the control of the luminance, the color temperature and the color of the LED lamp in the single firing line loop, and the control of the luminance, the color temperature and the color of the LED lamp in the single firing line loop cannot be realized by the conventional switch and the dimming switch.

Description

technical field [0001] The invention relates to the field of intelligent lighting control, in particular to a power line dimming system, which transmits digital control instructions through load power lines without changing the traditional electrical wiring requirements, and uses a controller to control the brightness, color temperature and color of LED lamps. Background technique [0002] With the development of semiconductor lighting technology, LED lamps have become more and more popular, especially ordinary families have begun to use LED lighting in large areas, and the advantages of energy saving, individuality and controllability of LED lighting have also been fully reflected. Recognition has also increased significantly. However, the traditional wall-mounted switch has a better user experience, but it cannot achieve uniform control of LED lighting brightness, color temperature and even color effects, which greatly limits the advantages of LED lamps. [0003] The trad...
