Safety warning light concept

Warning lights are generally used to maintain road safety. They are usually used in the development of tractors, mechanical equipment, etc., and control signals interlocking in electrical control circuits such as machinery, electric power, machine tools, chemicals, telecommunications, ships, metallurgy, etc., through sound and light alarms. Remind people to pay attention to safety from the visual and auditory aspects.

Classification of safety warning lights

The color of the warning light can be divided into: red warning light, blue warning light, green warning light, orange warning light, and three-color warning light.

Principle of safety warning lights

Many times, people's awareness of safety is very weak, and some lawless elements are getting more and more, which has led to many accidents. In order to reduce this kind of incident, people have invented safety warning lights to warn people, traditional The light source of the warning light is illuminated by the light bulb, and the light is emitted through the electric resistance wire according to the current. Usually, the tungsten light is internally used in the light bulb, and an inert gas is injected into the light bulb to achieve the purpose of light emission. Now with the development of LED technology in China, with LED as the light source, it is a solid-state light-emitting device that utilizes the luminescence effect of semiconductor. Unlike traditional bulbs, it does not shrink as the filament evaporates, resulting in reduced service life, no mechanical wear, long life, impact and vibration resistance. At the same time, the LED warning light has good light efficiency and strong visibility.

The role of safety warning lights

1. Remind others, remind people to stay away or confirm safe passage;

2. Remind yourself, pay attention to operational safety and safety environment confirmation.
