American manufacturer Avago Technologies has introduced a new 5mm ultra-high brightness LED lamp, including HLMP-Ex1A, 1B-xxxDV, and HLMP-Ex3A, 3B-xxxDV, etc. The series is lead-free and RoHS-compliant. 6 standard requirements, and can support the European information variable traffic sign standard EN12966-1.
Among them, Avago's products supporting the 15 degree viewing angle of the variable traffic sign include HLMP-Ex1A and 1B-xxxDV, which have a minimum illumination intensity of 12,000 mcd. The products HLMP-Ex3A and 3B-xxxDV, which support the 30-degree viewing angle requirements, have a minimum illumination intensity of 5,500 mcd.
Avago's new 15- and 30-degree viewing angle LEDs are specifically designed for outdoor signage and signage applications. The exterior of these lamps is UV-resistant with UV-resistant epoxy to reduce the effects of prolonged exposure to direct sunlight.
Avago's new LED products are available in red and amber, and are currently in volume production and available in volume.
Heat-Shrink Tubing is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. Optical Fiber Protection sleeves are used for holding and protecting fusion fiber splice point . It can also be used to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals, offering environmental sealing protection. Heat-shrink tubing is ordinarily made of nylon or polyolefin, which shrinks radially (but not longitudinally) when heated, to between one-half and one-sixth of its diameter.
Heat-shrink tubing is manufactured in a multitude of varieties and chemical makeups with the exact composition of each type being dependent on the intended application. From near microscopically-thin-wall tubing to rigid, heavy-wall tubing, each type has precise design and chemical additives that make it suitable for meeting any of a wide variety of environmental demands. Heat-shrink tubing is rated by its expansion ratio, a comparison of the differences in expansion and recovery rate.
