The principle of Wagner’s hammer is used in horns to generate sound. In this quite simple construction, pressing a button (a) closes the circuit in which an electromagnet (b) is located.  The magnetic field now created moves another switch (c), which immediately …

Warning lights are lights that indicate a hazard. Warning lights include rotating beacons, strobes as well as warning zone lights. Warning lights mounted on vehicles are part of the vehicle lighting.

A warning tone is emitted by an audible signal device to acoustically indicate a danger. The typical warning tone is a repeating beep, but there are also special types of warning sounders that emit white noise or other types of warning tones instead of a beep.

Warning zone lights are a sub-genre of warning lights. The special feature of these lights is that they do not emit a generally visible light signal into the environment as, for example, rotating mirror beacons or strobes do, but rather project a light signal onto the ground in front of, behind or next to …

e Watt (named after James Watt, unit symbol W) is the physical unit of power. In respect of lamps, Watt is often used as a dimensional unit for the brightness, although actually, it can only be used to describe the total power consumption of the lamp. But since a …

The term white noise refers to a broadband tone, i.e. a noise with a wide and unspecific frequency spectrum. In contrast to normal warning sounds with a clear frequency, broadband tones can be up to 5 dB quieter than a beep tone at a subjectively equal perceived volume. They are usually …

A wired LED is a type of LED that is conceived not for SMD-mounting, but for the traditional through-insertion mounting. Wired LEDs have no role in modern LED lighting technology.

Work lamps are small lamps of lower brightness whose light is usually emitted in an undirected manner, in contrast to work lights.

Headlights with uniform and mostly symmetrical beam patterns are called worklights. In contrast to headlights, it is not necessary to ensure glare-free illumination.
