Two-wire, three-wire, four-wire...how to choose a track light? What are the power requirements?
Track Light http://www.langladaled.com/product-list/led-track-light , a kind of light fixture composed of "track" and "lamp", also known as track light or track spotlight.
Because it can be moved and oriented according to needs, the angle of illumination can be adjusted at any time, and it is very convenient to increase or decrease or replace it. It is very popular in commercial, gallery, museum and other Lighting scenes.
How to choose the track lights?
What are the classifications of track lights? How to choose according to needs?
According to the number of conductive wires inside the guide rail, it can be divided into two lines, three lines, four lines, five lines, six lines, etc., of which two, three and four lines are the most commonly used track types.
The second and third wires are similar in that they are all controlled by a single loop (the lamps on the same rail can only be switched on and off, and cannot be controlled separately), the difference is that the second-wire rail has built-in 101 fire and two wires (the ground wire is generally external to the rail strip), and the three-wire rail ground wire It has become the design inside the guide rail, so there are 1 zero, 1 fire, 1 ground and three wires in the guide rail. Therefore, some professional and technical personnel, in the face of special application requirements, also have the common zero wire of the three-wire guide rail, and transform it into two circuits. The situation of realizing split-loop control (Note: It is not recommended to modify the behavior by yourself).

There are three fires, one zero and four conductive lines inside the four-wire guide rail, that is, the same guide rail can be divided into three loops of control. When installing with the four-wire guide rail light with the gear adjustment function, the needs of different scenes can be realized. .
e.g:
On a four-wire track, No. 1, No. 2, No. 3, No. 4 four four-wire rail lights, No. 1 light is adjusted to the first gear, No. 2 light is in the second gear, and No. 3 & 4 lights are in the third gear. At this time, with 3 switches, multiple scene changes can be realized:
①Switch 1 controls light 1
②Switch 2 controls light 2
③Switch 3 controls lights 3 & 4
This is the sub-control system of the four-wire guide rail.

Five-wire and six-wire are relatively rare, but there are also some applications, which are commonly used in DALI control systems, and two of them are used as DALI signal lines.
To sum up, according to the scene control requirements, if only a single loop is required to control the track lights of the 2/3 line track, more than 4 lines are required for separate control, and 5/6 lines are used if system control is required.
For different line tracks, there are no special requirements for the use of power supplies, which can be selected according to the power and function of the lamps. However, since the power supply of the rail light is mostly built-in installation (built-in lamp body or built-in rail box), the ambient temperature of the power supply is high, so the heat dissipation function of the power supply must be good.
The track of the track light is different from the slide rail, and the light fixture cannot slide directly on it. If you need to change the position, you need to remove the light first, and then snap it to the new position.
Common rails are 0.5M, 1M, and 1.5M. According to different lengths and installation requirements, rail accessories can be used for splicing and installation.
