What are the types of light transmittance of PC covers for LED tubes? The luminous flux of the LED lamp tube has a great relationship with the PC used in the LED lamp tube. The transmittance of each PC transparent cover is different, so even if it is the same power, the same lamp beads, the same The LED lamps are equipped with PC covers with different light transmittances, and the brightness is
What is the reason for the crack of the LED lamp pc cover The reason for the cracking of the pc cover is that the molecular chain structure of the PC is damaged and the molecular chain is broken, resulting in cracks on the surface. There are several factors that affect the molecular chain structure: Use repeatedly. When used repeatedly, the molecules of the product will fission under the actio
Introduction: LED designers have achieved many advantages by choosing PC (not glass and PMMA), including stronger impact resistance and heat resistance, improved flammability levels and increased design flexibility. With the increasing adoption rate of LED lighting, lighting manufacturers are pursuing materials other than traditional materials for lighting applications to promote innovative d
What is an LED tube? Analysis of the principles and advantages of LED lamps There are many occasions that have chosen a more environmentally friendly and useful lamp-LED lamp, so what is an LED lamp? What are its advantages? Now, the editor takes everyone to walk into the world of LED lamps. LED lights are actually commonly known as fluorescent tubes, and commonly known as "light tubes" are
What is the fire rating range of PC covers for LED tubes? Because the PC cover of the LED is a plastic material, its fire protection standard is based on: flammability UL94 rating. Its fire rating range is as follows: The flame retardant grade of plastic increases from HB, V-2, V-1 to V-0: HB: The lowest flame retardant level in the UL94 standard. It is required that for samples 3 to 13 mm th
LED fluorescent lamp PC lampshade LED fluorescent lamp PC lampshade is a kind of LED fluorescent lamp accessories. It is to better gather the light and make the light more concentrated. Heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable and so on. Chinese name LED fluorescent lamp PC lampshade is used for LED fluorescent lamp
Difference: The former uses modified polypropylene as the main raw material, which is easy to use, reduces damage to the road surface, and has a wide range of applications. It has good insulation performance, high temperature resistance, strong compression resistance, light weight, convenient construction, smooth inner and outer walls, low friction, long service life and good performance. MPP pow
CPVC pipe extrusion process Chlorinated polyvinyl chloride resin (hereinafter referred to as CPVC) was successfully developed by BF Goodrich in 1958. It is a chlorinated product of polyvinyl chloride resin (PVC). The chlorine content of chlorinated PVC can be 57% to 64% to 75%, with the increase of chlorine content, the corresponding temperature resistance, rigidity, chemical resistance, flame
