In 1959, people discovered the tungsten halogen cycle principle and produced a tungsten halogen lamp, which injected new vitality into the heat radiation source. The lamp has a small volume, the light maintenance rate is over 95%, and the light efficiency and life are obviously superior. Incandescent lamp. In recent years, tungsten halogen lamps that can be directly applied to the grid voltage of 220V or 110V have been produced, and their sizes can be as small as Ø14×54mm. They have excellent filament stability and shock resistance. The bulbs are transparent and frosted. Different specifications, the inner fuse is in accordance with IEC A32-2 standard, the lamp head is G9 type easy to connect, its main technical parameters are shown in Table 1. In recent years, a variety of new types of energy-saving halogen-tungsten lamps have been introduced. For example, JD-type and JDR-type novel tungsten-halogen lamps are made by coating TiO2/SiO2 infrared reflective layer technology (IRC) on quartz bulbs, through visible light transmission. The process of reflecting the infrared rays back to the filament makes the light efficiency of the lamp increase by 30%-45%, and the service life is 3000 hours. Since the tungsten halogen lamp has a particularly good color rendering property and is small in size and easy to decorate, it is still popular and widely used.
Material characteristic: Using high quality aluminum extruded shutter profiles, multi-layer painting or film layer surface have excellent scratch resistance function, not decay, wearable and anti-collision.Nice white profiles, accepting mass customization according to users requirements(light gray, brown, cream, wood, fused, sand color and light sand color ,etc.)
Integrated protection and decorative features together,the best replacement of traditional theft network security replacement; flexible way open ways, supporting hand control, group control. The door could be your safe rescue channel when in emergency.
When in state of close, support ventilation and lighting, this contribute to enhance the cooling and heating effect of air conditioner, ensure safety, comfortable, energy saving, noise isolation and aesthetics.
