Note that when you select a thermostat soldering iron, soldering temperature of 260 ℃, Guangzhou box lights, LED time iron and first contact pads not exceed 3S (note electric iron welding must be grounded, the operator should wear a wrist strap or blow ion fan) Four high-power LED driver circuit due to follow the diode voltage characteristic curve, if the drive voltage is floating the corresponding drive current drift is large, easy to damage the lamp beads, Zhengzhou box lights, it is recommended that the use of more stable constant current drive power or IC, rather than using constant drive power or IC. High-power LED as a light source with a small size, low power consumption, low heat, long life, fast response, low voltage security, weather resistance, and good directionality advantages. Housing available PC pipe production, high temperature of 135 degrees, low temperature -45 degrees 1 life: high power LED lamp life up to 50,000 hours 2. Energy Saving: saving more than 80% of the high-pressure sodium lamp 3 green . High-power LED lamps do not contain lead, mercury and other pollution elements, no environmental pollution 4. Security: impact resistance, light boxes lights, earthquake and strong, led emitted light in the visible range, no ultraviolet (UV) and infrared ( IR) radiation. No filament and glass shell, no fragmentation of traditional lamp problem, the human body without harm, no radiation; Zhengzhou Lightbox light bar _ beam lighting (Online) _ light bar boxes by far Lighting Technology Co., Ltd.
