The LED tube has developed from an early all-plastic tube to a half-aluminum and half-plastic structure, which solves the problem of poor heat dissipation of the plastic tube to a certain extent, and also solves the problem of the lampshade. This will select a good LED shade for us. , PC shade provides useful help. Suitable for interior decoration and lighting. Currently, all high-quality LED interior lights have glass shades.
The customization of the ceiling lamp shade is especially suitable for sealing LCD edges, film printing and other occasions where a small temperature rise is required. Low calorific value can solve the problem of high calorific value in lighting printing equipment and unbearable problems for personnel. Automatic cooling is used to forcibly dissipate the heat from the radiator by means of a cooling device such as an electric fan. The characteristics of the lampshade are high heat dissipation efficiency and small device size.
Advantages of PC lampshade: Light transmittance: PC lampshade has a high light transmittance of up to 89% and can be used with glass. UV-coated boards will not yellow when exposed to sunlight, fog and poor light transmission. Ten years later, the loss of light transmittance is only 6%, the loss rate of PVC is 15% to 20%, and the loss rate of glass fiber is 12%%-20%. Impact resistance: The impact resistance of the PC lampshade is 250-300 times that of ordinary glass, 30 times that of acrylic sheets of the same thickness, and 2-20 times that of tempered glass. There were no cracks when dropped below 3kg with a two-meter hammer.
Anti-UV: The PC lampshade is coated with anti-UV coating on one side and anti-condensation treatment on the other side, which integrates anti-UV, heat insulation and anti-dripping functions. It blocks the penetration of UV rays and is suitable for protecting valuable artwork and exhibits from UV rays. Adaptability: PC lampshade will become brittle at -100°C, will not soften at 135°C, and its mechanical properties will not change significantly in harsh environments.
