Basic knowledge of LED lighting engineering

To understand the corresponding LED products; many kinds of LED products, to do lighting engineering to use the following products

, 1 digital tube, also known as LED guardrail tube, LED guardrail lamp, LED light; this product to be used for contour building installation, KTV door or advertising signs, and

Highway and bridge guardrail lighting project; can achieve the colorful water, chase, scan and other effects; if a LED digital tube screen (LED digital signature) can produce a variety of dazzling animation and flower type, you can also play video;

Text and pattern.

LED digital tube to classification:

According to the effect can be divided into:

Monochrome often bright red, yellow, blue, green, white, colorful; divided into: single segment colorful gradient jump; really really six, eight segments, 16 segments, 16 segments, 32 segments, 48 segments;

According to the control method:

Internal control and external control; internal control LED fence tube is the program directly into the IC chip LED guardrail tube, connected to the power directly out of flower type; external control

In short we need external controller; controller is divided into offline system and online system; on-line system is refers to the attachment control system work on a computer (for LED digital tube screen); offline system is not attached

On the computer, after receiving the power to enter the control signal to drive the LED guardrail tube.

2, rainbow tube aka LED lights, LED Meinai lamp; is one of the most commonly used products in lighting engineering, and the price is relatively cheap, LED lighting products of many customers favorite. Mainly applicable to the cost is not high, the effect is not too fancy places; can do house or sign a word or other metal profile; edge; the dark trough decoration smallpox or KTV.

LED rainbow tube classification: round line, round three line, flat line, side line, flat three lines, flat four lines, flat five lines, flat seven lines; red, yellow, blue, green, white, red and blue, red and green, red and yellow blue, red and yellow blue green; general as the row jump through controller can achieve the flashing effect.

3, decorative lamp series LED star light (LED light string), LED lamp, LED lamp falls, LED stars. These are generally used for ornamental flowers or small landscape. For example: a tree to do a lighting effect, you can use more than a string of LED star lights, the branches around, and then flashing through the controller, it becomes a number of colorful flashing LED Christmas tree lights.

Many products, not on the list, commonly used are LED point source, LED neon light, LED electronic display, LED lamp, LED high power wash wall lamp, LED underground lamp, LED underwater lights, LED landscape tree, LED plastic characters in addition to metal halide lamp, sodium lamp light is often used.
