LED aluminum profiles are a popular choice for housing LED strips, as they provide a sleek and modern look while also protecting the LED strip and providing better heat dissipation. One important factor to consider when choosing an LED aluminum profile is the light transmittance of its cover, as it can greatly affect the brightness and quality of the light emitted by the LED strip.
Light transmittance is a measure of how much light can pass through a material, expressed as a percentage. In the case of LED aluminum profiles, the cover material can be made of various materials, such as polycarbonate, acrylic, or glass, each with its own level of light transmittance.
Polycarbonate covers, for example, have a high level of light transmittance, usually around 90% or higher. This means that most of the light emitted by the LED strip can pass through the cover and be visible to the eye, resulting in a bright and uniform illumination. Polycarbonate covers are also durable and shatter-resistant, making them a popular choice for outdoor and high-traffic applications.
Acrylic covers, on the other hand, have a lower level of light transmittance, usually around 80-85%. This means that some of the light emitted by the LED strip may be absorbed or reflected by the cover, resulting in a slightly dimmer and less uniform illumination. Acrylic covers are less expensive than polycarbonate covers and can be easily customized and shaped, making them a good choice for decorative applications.
Glass covers have the lowest level of light transmittance among the three, usually around 70-80%. This means that even more of the light emitted by the LED strip may be absorbed or reflected by the cover, resulting in a dimmer and less uniform illumination. Glass covers, however, have a high-end look and feel and can provide a unique visual effect, making them a popular choice for high-end applications such as museums and art galleries.
In conclusion, the light transmittance of the cover material is an important factor to consider when choosing an LED aluminum profile. A high level of light transmittance, such as that of polycarbonate covers, can result in a bright and uniform illumination, while a lower level of light transmittance, such as that of acrylic or glass covers, can result in a slightly dimmer and less uniform illumination. By selecting the right cover material, you can achieve the desired lighting effect for your application and enhance the overall aesthetics of your space.
