Outdoor installation of LED line lights pays more attention to waterproof and firm installation of light bars. Therefore, outdoor installation often adopts the way of fixed groove. Where the connection needs to be cut, the method is the same as indoor installation, except that waterproof glue is needed to consolidate the waterproof effect of the connection point. Then fix it with a special fixing clip, which can be drilled with an electric hammer, or fixed with a plastic expanding pipe and screws.
It is a semiconductor diode, which can convert electric energy into light energy. Light-emitting diodes (LEDs), like the developing tubes of ordinary diode LED chips, are all composed of PN junctions and also have unilateral conductivity.
Theoretically, blue LED can produce white light by combining the original red LED and green LED, but white LED is rarely made in this way.
At present, most white LEDs produced are made by covering blue LEDs (near ultraviolet, wavelength 450 nm to 470 nm) with a layer of light yellow phosphor. This yellow phosphor is usually made by grinding cerium-doped yttrium aluminum garnet (Ce3+:YAG) crystal into powder and mixing it in a dense binder.
With the continuous development of the industry, the breakthrough of technology and the vigorous promotion of application, the light efficiency of LED is also constantly improving, and the price is also declining. The emergence of new combined die also makes the power of a single LED tube (module) continuously improve. Through the continuous efforts of the same industry, the breakthrough of new optical design and the development of new lamp types, the situation of single product is expected to be further reversed.
