Description
Technical Field
The utility model belongs to the technical field of the electrical lighting, especially, relate to a control circuit for LED lighting apparatus.
Background
In the present life and production, the popularization rate of the LED lighting equipment is very high, the LED lighting equipment has the advantages of long service life, low energy consumption, high efficiency, energy conservation and the like, and the LED lighting equipment also has the defects for household or factory office areas: when a wall switch of an LED illuminating lamp is turned off, the lamp can slightly shine or twinkle sometimes, the root cause is that a three-phase four-wire system power supply system is arranged in a living area and a factory area at present, the potential of a zero line is increased due to unbalanced three-phase load, the resistance of a grounding loop at the center point of a transformer is too large, and the zero line can have electricity to the ground. The slight lightening of the LED lamp is caused by induction electricity, although the switch is in an off state, a small voltage difference exists between two ends of a power supply of the LED illuminating lamp, and the small voltage difference is the reason for the slight lightening of the LED illuminating lamp. The manual switch controls the zero line, which is also the reason for slight brightness of the LED illuminating lamp, and only when the live line and the zero line are disconnected, the slight brightness can be eliminated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a LED lighting control circuit to solve LED lighting apparatus and appear bright technical problem a little after closing switch.
In order to achieve the above object, the utility model discloses a specific technical scheme of LED lighting control circuit as follows:
the LED lighting control circuit comprises LED lighting equipment and an intermediate relay, wherein two ends of the LED lighting equipment are respectively connected with a first auxiliary contact and a second auxiliary contact of the intermediate relay, and the first auxiliary contact and the second auxiliary contact are respectively connected with two ends of a coil of the intermediate relay; two ends of the intermediate relay coil are respectively connected with a zero line and a live line of a power supply; and a power switch is arranged between one end of the intermediate relay coil and the power supply.
Furthermore, a small-capacity capacitor is arranged between zero and live wires of the power supply and is used for eliminating filtering.
The utility model discloses a LED lighting control circuit has following advantage: a relay is connected between a controller lead and a power lead of the LED lighting device and used for isolating the controller from a power supply, the voltage difference between leads at two ends of the LED lighting device is eliminated, and a small-capacity capacitor is connected in parallel in a zero-live wire to eliminate filtering, so that the LED lighting device is completely extinguished after a switch is closed.
Drawings
Fig. 1 is the schematic diagram of the structure of the LED lighting control circuit of the present invention.
Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
