Semiconductor luminotron lamp local damage bypass protector

Abstract

A by-pass protective device of local damage at semiconductor luminous tube LED lamp is prepared as parallel-connecting a protective by-pass on each semiconductor luminous tube LED lamp bulb, providing current by-pass for damaged LED lamp bulb according by corresponding protective device to maintain complete lightening lamps and lanterns to work properly and continuously when any semiconductor luminous tube LED lamp bulb is damaged.

Description

technical field [0001] The invention discloses a partial damage bypass protection device for a semiconductor light-emitting tube lamp. Background technique [0002] At present, most of the street lamps used on the road are 150W-400W, which consume a lot of power and put a lot of pressure on the energy supply, and can only be used normally when the power is sufficient. When there is a shortage of electricity supply, the lighting of street lamps will be limited. In addition, in practical applications, for the sake of power saving, the brightness of street lamps needs to be adjusted at different time periods. For example, in the dead of night, the street lamps will be dimmed to save electricity. Ordinary street lamps use ordinary fluorescent lamps or sodium lamps. In order to reduce the brightness, they can only be allowed to work at a state lower than the rated power. Working in an abnormal working state lower than its rated power for a long time will easily damage the lamp t...

Problems solved by technology

[0005] Semiconductor light-emitting tube LED lighting fixtures often use multiple semiconductor light-emitting tube LED bulbs in series to increase power and illuminance, but the common problem is that in order to meet a variety of connections, the connection of semiconductor light-emitting tube LED lights is in series or parallel. If the semiconductor light-emitting tube LED lamp adopts a series structure, if there is no bypass device, any one of the semiconductor light-emitting tube LED bulbs is damaged (open circuit), which will cause the entire circuit current to be disconnected, and other undamaged semiconductor light-emitting tube LED bulbs will also fail due to no current. normal work no longer glow

If the semiconductor light-emitting tube LED light adopts a parallel structure, it can still be used normally if a few lights are damaged, but not too much damage. If there is too much damage, the regulated power supply will add the average current to other semiconductor light-emitting tube LED lights, so that First, it will burn more semiconductor light-emitting tubes and LED bulbs. In addition, after parallel connection, the current is very large, and the heat is relatively high. If the heat is too high, the LED bulbs will be seriously damaged and the life of the LED lights will be reduced. Therefore, the existing Most LED lamps adopt a series structure, which inevitably has the problem that the aforementioned individual bulbs are damaged and the entire lamp cannot be used.
