5 Types of Command Tower Lights

Lighthouses, no doubt, are giant beacons that target tower-shaped structures that are markedly equipped with powerful light-emitting devices. It is usually set at the coast, islands, reefs and harbour gates to mark dangerous areas and for ships to determine the ship's position and guide the ship's navigation. The beacon towers serve the same purpose, illuminating the way people are going. So, do you know what the light of the beacon tower is?

5 types of light tower lights

✔️Carbon arc lamp

An electric light source that emits light by a discharge arc generated when two carbon rod electrodes in contact are separated after being energized in the air. The carbon arc lamp was invented by the British H. David in 1809;

✔️Incandescent lamp

Incandescent lamps, also known as tungsten filament lamps and light bulbs, are electric light sources that heat the filament to an incandescent state and emit visible light by thermal radiation.

A light source that produces light by heating an electric current through a filament to an incandescent state. Incandescent lamps are the earliest electric lamps, which are made of heat-resistant glass and contain tungsten filaments.

Remove air from the bulb to avoid oxidation of the filament, or refill with an inert gas (such as argon) to reduce the thermal evaporation of the tungsten filament. Because only a small part of the power consumed by the filament is converted into visible light, the luminous efficiency is low, generally 10 to 15 streams/watt. But it is easy to manufacture and low cost.

✔️LPS

The low-pressure sodium lamp is an electric light source that uses low-pressure sodium vapor discharge to emit light, and its glass shell is coated with an infrared reflective film. The low-pressure sodium lamp emits a single-color yellow light, which is used in places where there is no requirement for light color;

✔️HPS

When the bulb is started, an arc is generated between the electrodes at both ends of the arc tube. Due to the high temperature of the arc, the liquid sodium and mercury gas in the tube is heated and evaporated into mercury vapor and sodium vapor. The electrons emitted by the cathode strike the discharge material during the movement to the anode. The atoms are ionized or excited to obtain energy, and then return to the ground state from the excited state; or change from the ionized state to the excited state, and then return to the ground state in an infinite cycle. At this time, the excess energy is released in the form of light radiation, so light is produced.

✔️LED lights

LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light.

The microscope light source in optical instruments is mainly used to supplement light for microscope observation. It is generally supplied by a voltage of 220V, and the power is generally about a few watts. The microscope light source is inlaid with lamp beads, which are generally LED lights. The lamp generates very little heat, so it has little effect on the control of the temperature of the product during observation.

In addition, there is another kind that is not composed of LED lamp beads, but composed of lamp tubes. Such lamps have external four-plug and built-in four-plug interfaces. There is also a two-plug, such a light source is only suitable for the light source installed on the microscope, if you feel that the light is still relatively dark. There is also a kind of external use, you can adjust the lamp head at will, this kind of light is more convenient.

In the end

The above are the common lights of command lighthouses. Among them, led lights are now the most widely used.
