The invention relates to a photovoltaic power and electric supply switching circuit of an LED fluorescent lamp. The photovoltaic power and electric supply switching circuit comprises a solar battery. The solar battery charges a storage battery through a charging circuit, the storage battery is connected with the input of a single chip microcomputer through a voltage detection device, the storage battery is connected with the first input of the LED fluorescent lamp through a DC / AC converter and a switch controller in sequence, an electric supply is connected with the second input of the LED fluorescent lamp, the first output of the single chip microcomputer is connected with the charging circuit, the second output of the single chip microcomputer is connected with the switch controller, the third output of the single chip microcomputer is connected with the electric supply, the fourth output of the single chip microcomputer is connected with an alarm, and the fifth output of the single chip microcomputer is connected with a status indicator. The photovoltaic power and electric supply switching circuit is reasonable in design and simple in structure. Two paths of circuits are adopted to supply power, it is ensured that the electric supply supplies power in long-term rainy days and solar energy supplies power in sunny days, and the environmental protection, energy saving and economic effects are achieved.
Description
technical field [0001] The invention relates to the field of a lighting device with power failure delay, in particular to the circuit field of an LED fluorescent lamp with switching function between photovoltaic and commercial power. Background technique [0002] In 1907, Round reported the discovery of LEDs on SiC. Then, after a large number of unremitting research and exploration by scientific and technological personnel, especially Shuji Nakamura's outstanding work on blue LED. Nowadays, as the fourth-generation light source of energy saving and environmental protection, LED is more and more favored and supported by governments all over the country. The rapid promotion of LED light sources is mainly due to its seven characteristics: 1) High energy efficiency: the luminous efficiency of LED chips has reached 180lm / w. 2) Environmentally friendly and non-toxic: currently widely used fluorescent lamps contain mercury vapor, while LEDs are all solid-state and have no uncontr...
