Basic introduction to warning lights

Warning lights were first used in military warning, aviation, police and so on. At first, people may not have known that warning lights can reach such a glorious level today. The warning lights have been widely used in military, aviation, commercial public facilities and so on. This gives the warning light a new opportunity and challenge. The subdivision of the market, manufacturers of different designs can be assigned to their own markets. With the development of urbanization, the demand for traffic warning lights is also huge. This is the first opportunity since the start of the warning light. The warning lights have been comprehensively improved in terms of style and technology.

Warning lights can be roughly divided into single light warning lights and sound and light warning lights. Hole single light warning light, etc. The combined warning light has a combined warning light component, a combined warning light sound component, and a combined warning light component. Among them, the combined warning light sound component signal indicator light is also called alarm light and signal light. There are many varieties and wide uses.

Warning lights can be divided into three categories according to the different light sources:
1. Bulb type

Bulb-type warning lights are actually similar to the light bulbs we used to use. According to the current through the resistance wire to emit light, a spiral black wire is generally used, and an inert gas is injected into the lamp. Features: The operating voltage is 10% lower than the extra voltage of the bulb, the lifespan is increased by 4 times, and the power consumption is as low as 85%, a decrease of about 30%. When the operating voltage is increased by 10%, the lifespan is shortened by 30%, the power consumption is increased by about 16%, and the brightness is increased by about 40%. The standard life of a general light bulb is about 1000-1500 hours.

2. LED type warning light

LED warning lights are made of light-emitting diodes, so the conversion power of photoelectricity is very high, and they are energy-saving and long-life lamps. They are now widely used in shopping malls. The life of LED is affected by factors such as overvoltage and ambient temperature, but it will not gradually become thinner due to the evaporation of the filament like a light bulb, and there will be no mechanical wear, so it can resist shock, vibration and longevity without the need for a special anti-vibration structure. long.

3. Xenon tube strobe type

A xenon tube bulb that puts a relatively large amount of energy into the bulb in a short period of time and instantly releases high-power light. Compared with continuous light bulbs, it needs to introduce a very large amount of electric energy in an instant and emit a large amount of light (energy line). Because xenon gas has advantages in production (material selection) and application (low luminous voltage), the gas injected into this bulb is Xe gas, and the name of xenon lamp tube comes from this. The xenon tube bulb can be fixed with shock resistance, so it has good shock resistance, and the published spectrum is close to the sunlight, and it flashes like the camera light during operation, so the visibility is extremely strong.

In the traditional sense, warning lights are generally used to maintain road traffic safety, often used in the development of police cars, engineering vehicles, fire engines, ambulances, road maintenance vehicles, mechanical equipment, etc.; but at present, the usefulness of warning lights is far from If it is so narrow, if we pay attention, we will find that it can be used in various fields such as factory production lines, parks, buildings, sailing seas, public places, and public security. The development of warning lights has now broken the original bottleneck and has a broader development space.
