Abstract

Disclosed is an efficient long-life low-cost energy-saving LED lighting lamp. After a mains supply is rectified, pulse parameters of a power supply of the LED lighting lamp are controlled by a filter circuit and a switching triode, so that the LED lighting lamp is driven to work. However, the circuit serving as a switching driving power supply of the LED lighting lamp is not stable enough, an electrode b of the switching triode is serially connected with a biasing resistor and connected with an electrode c of a control triode, an electrode b of the control triode is respectively connected with an electrode e of the switching triode and a sampling resistor, and more stable voltage b and e of the control triode is reference voltage matched with the sampling resistor to keep current value of the LED lighting lamp constant. By the aid of four common components, the circuit is efficient, long-life, simple, easy in debugging and capable of achieving constant current.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to an LED lighting energy-saving lamp with high efficiency, long life, low cost and simple circuit. Background technique [0002] At present, when designing circuits for known LED lighting lamps, most designers design the circuits using some chips as driving power sources, which makes the LED lighting lamps costly, complicated and difficult to debug. Contents of the invention [0003] In order to overcome the defects of high cost, complex circuit, and difficult debugging of LED lighting lamps, the present invention provides a high-efficiency, long-life, and low-cost LED lighting energy-saving lamp. achieve constant flow. [0004] The technical solution adopted by the present invention to solve the technical problem is: after rectifying the commercial power, the pulse parameters of the power supply of the LED lighting lamp controlled by the filter circuit and the switching triode are used t...
