LED lamp circuit and LED lamp socket

Abstract

The invention provides an LED lamp circuit comprising a constant-current diming source for providing constant current for the whole circuit and turning on an LED lamp; the LED lamp in series connection in the circuit and used for illumination; a communication interface connected with the constant-current diming source and used for controlling the output current of the constant-current diming source. The LED lamp circuit is decreased in cost, prolonged in service life, and reduced in fault points, and may achieve centralized control and centralized dimming. The invention further provides an LED lamp socket comprising two reeds, a conductive sheet, an insulated sliding member, and an elastic member. When the LED lamp is not inserted into the LED lamp socket, the elastic member is in a stretched state so that the reeds and the conductive sheet are in contact to form a first loop. When the LED lamp is inserted into the LED lamp socket, the two copper sheets of an LED lamp plug push the insulated sliding member, the elastic member is compressed and the conductive sheet and the reeds are separated, the first loop is disconnected, the two copper sheets of the LED lamp plug contact the reeds respectively, and the LED lamp acquires current so that a second loop is formed. No matter whether the LED lamp is inserted into the LED lamp socket, the operation of the whole LED lamp series circuit is not influenced. The LED lamp is easy to plug in and out and simple and practicable.

Description

Technical field [0001] The invention relates to the field of circuit devices, in particular to an LED lamp circuit and an LED lamp socket. Background technique [0002] Lighting lamps are an indispensable living facility for every family. With the progress of the times, incandescent lamps have gradually faded out of people's vision, replaced by more safe, reliable and energy-saving LED lamps. [0003] However, the ordinary LED lamp circuit is driven by one LED power supply to drive one LED lamp, and the production cost and engineering installation will increase the overall cost. The power supply is driven by a switching power supply. The number of power supplies is as large as the number of lamps. It is difficult to dissipate heat. It is scattered in each lamp. There are many components and the number of fault points increases. It is inconvenient to maintain and cannot be centralized management. There are also problems such as high wiring engineering costs and inconvenient install...
