Problems solved by technology

At present, in the field of solar lamps and lanterns, in order to realize the automatic switching of lamps during the day and night, people usually set some photosensitive sensors on the single-chip microcomputer of the lamps, so that the photosensitive sensors can be used to sense the changes of ambient light, and then control the lighting of the lamps through the single-chip microcomputer. Switch, the entire photosensitive process is complicated and consumes power, which needs to be improved urgently

[0046] Others are the same as embodiment one.

[0047] The shunt resistor RA added in parallel between the collector of the transistor Q2 and the emitter of the transistor Q2 in the TLCC drive circuit has a unique function of shunting and dividing power consumption, which can make the positive terminal of the LED load flow into the negative terminal of the LED load. The circuit is divided into two paths. One of the two currents directly flows through the collector of the transistor Q2 to the emitter of the transistor Q2 , while the other current flows through the shunt resistor RA and then flows to the emitter of the transistor Q2 . The two currents are finally brought together at the emitter of the transistor Q2, and then connected to the base of the transistor Q1 to form a loop to the ground through the constant current resistor Rs.

Description

【Technical field】 [0001] The invention relates to the technical field of driving circuits, in particular to the technical field of a solar intelligent control type TLCC (Triodelinear constant current) driving circuit. 【Background technique】 [0002] LED lights are recognized as the fourth-generation green light source, with many advantages such as high efficiency, long life, safety and environmental protection, small size, high reliability, and fast response speed. The technology is mature and widely used in various fields. Since the LED is a constant current load, it must be driven by a constant current to ensure that it always maintains a safe and stable working condition. Existing LED lamp drive circuits usually rely on dedicated constant current drive chips for constant current drive. Therefore, the production capacity of the product is greatly affected by the market supply of the chip, and the price of the product is likely to change with the price increase of the chip....
