A Complete LED Aluminum Profile System

LED Aluminum Profile

The LED aluminum channel’s main raw material is aluminum. It is extruded by the machine into various sizes and shapes. The size and shape of each LED aluminum profile are different, and there are many types: Embedded LED aluminum profile, Surface-mounted LED aluminum profile, Wall series LED aluminum profile, etc.

In addition, the color of the LED aluminum profile can also be selected. The regular ones are silver and black; you can choose according to your needs. It also supports customizing other aluminum profile colors if you need them.

LED Aluminum PC Cover (LED channel diffuser)

The LED PC Cover (LED channel diffuser) is one of the accessories of the LED aluminum profile. Its function is to protect the LED strip lights, improve the lighting effect of the LED light, and make the LED light distribution more uniform. In addition, it will not directly harm people’s eyes, thereby achieving better LED lighting effects.

We mainly sell material PC covers, which have many colors to choose from: clear PC covers, diffuser PC covers, opal PC covers, and black PC covers. You can choose according to your needs.

Some LED channel diffusers are Free-bending LED aluminum profile series and can be bent into a circle, which is a free arc series, while some LED profile covers can only be straight.

Different PC covers have different light transmissions.

The following are the light transmittances of LED PC covers of different colors for your reference. Choose the right PC diffuser based on the lighting effect you want.

LED PC Cover (LED channel diffuser)

►Clear – light transmittance 95-90%. If you need a little more brightness, this PC cover can achieve maximum brightness.
►Diffuser – 80-70% light transmittance. Textured brightness is above average.
►Opal – 65-60% light transmittance. Medium brightness, bright, and warm.
►Black – 35-30% light transmittance. The focus is not on brightness; this is a special engineering use, mainly to enhance the atmosphere.

LED Aluminum Profile End Cap
