Problems solved by technology
[0003] Due to the current scarcity of integrated circuits, it is difficult for most companies to meet customer order needs; with the expansion of market demand, high-intensity power linear integrated products cannot meet market demand
[0004] The current linear photoelectric integrated floodlights have very few solutions to adapt to different national power grids. The temperature of the integrated circuit chip is too high, and the performance of high-power products is unstable, resulting in limited product sales; among them, integrated dual-voltage integrated floodlights are only available. It can adapt to the application of low-power products, has poor lightning surge resistance and low optical conversion efficiency; the linear dual-voltage integrated scheme switching integrated circuit chips cannot meet the needs of trial production. A new type of dual-voltage switching circuit is designed for the above problems.

The invention relates to the related field of lighting technology, in particular to a novel double-voltage switching circuit which comprises a rectifying circuit module, a switching circuit module, a first main control circuit module, a second main control circuit module, a third main control circuit module and a fourth main control circuit module. According to the invention, the system operation is realized by adopting the characteristics of the MOS switch and the mode that the main control chips IC1, IC2, IC3 and IC4 are connected in parallel during low-voltage input, a stable and high-efficiency conversion device is realized by the switching circuit module, the parallel connection relationship between the main control chips conforms to the high luminous efficiency function and is different in approach but equally satisfactory in result with an integrated circuit to achieve technical resonance, and the situation that no chip can be used in a photoelectric integrated dual-voltage switching integrated circuit is eliminated.
Description
technical field [0001] The invention relates to the related field of lighting technology, in particular to a novel dual-voltage switching circuit. Background technique [0002] With the explosive development of the LED lighting industry in recent years, LED lighting companies have increasingly strict requirements for new energy saving in addition to the stability of lamps and lanterns as always; product innovation is the source of life for enterprises; this means that by innovation The new force driven by the industry is generally optimistic, but there are still certain limitations based on technical reasons, and new technical applications are still worthy of our exploration and research. [0003] Due to the current scarcity of integrated circuits, it is difficult for most companies to meet customer order needs; with the expansion of market demand, high-intensity power linear integrated products cannot meet market demand. [0004] The current linear photoelectric integrated...
