Warning light is a kind of light that can light up in one or several colors to alarm in various environmental situations. Some warning lights are also equipped with sound components, which can send out loud alarm sounds.

Light source and characteristics of warning light

1 bulb

According to the current, the light is emitted through resistance wire, usually spiral tungsten wire, and inert gas is injected into the bulb

characteristic:

The use voltage is 10% lower than the rated voltage of the bulb, the service life is increased by 4 times, and the consumption power is reduced to 85%, about 30%

When the voltage is increased by 10, the service life is shortened by 30%, the power consumption is increased by 16%, and the brightness is increased by 40%. The standard life of a general bulb is about 1000-1500 hours

2LED

LED is a solid-state light-emitting device that uses the semiconductor's telephone light-emitting effect. Like general semiconductors, LED's life is affected by voltage, surrounding temperature and other factors, but it will not gradually thin due to the evaporation of filament like a bulb, and there will be no mechanical wear. The anti-seismic structure without characteristics can also resist impact, vibration and long life. In addition, LED's photoelectric conversion efficiency is high, which is the complex of energy saving and long life. Xe gas is mostly used, so xenon lamp is also named

The xenon lamp bulb can be fixed by the shock resistance method with good shock resistance. The spectrum of xenon lamp is close to that of natural light. It works in the same way as the flash of camera, so it has strong visibility.

Application of warning light

After years of development, warning lights are widely used in dozens of industries, such as electric power, machinery, metallurgy, industry and mining, security, transportation, water treatment, food, packaging, construction, port, textile, etc.

Selection of warning light

According to the use purpose, working environment and other factors, the following factors shall be mainly considered in the selection of warning lights:

Brightness of surrounding environment

Distance from observation point

Life and cost of light source

Noise, pollution and strong vibration or impact

The impact of sudden problems such as light source damage on safety

Ease of use and maintenance

Different products should be selected under different use requirements and environmental characteristics, but the convenience and economy of maintenance should be considered in all occasions.
