LED street lights are installed outdoors and are easily damaged by lightning strikes or surge voltages, so lightning protection units need to be designed. The lightning protection of the street lamp is divided into two levels. The first stage is to protect the direct lightning strike, and the metal lamp pole is grounded for processing. The second stage is to protect the conducted lightning and inductive lightning strikes, grid voltage fluctuations, etc., using the surge absorber Varistor as the main component to design the lightning protection unit. Click to enlarge The new thermal protection surge absorber (TMOV) developed by Celtic simplifies the lightning protection design of LED street lights. The new TMOV integrated thermal fuse and Varistor are safely isolated before the Varistor fails fire, with UL1449 3rd Edition certification. LED drive power supply overcurrent protection design Click to enlarge The traditional LED driver power supply uses current fuse as the overcurrent protection. Here, the new design of the thermal protection wirewound fuse resistor is introduced. It has better price and performance than the current fuse and has better safety performance than the ordinary wirewound resistor. A Thermal Protection Surge Absorber Thermo-fuse Varistor is designed at the front of the power supply to prevent surges or lightning strikes. When the ordinary wirewound resistor is used as an overcurrent protection, it requires a fault current of 4 times or more of the rated current to be quickly disconnected. It has a long disconnection time at twice the rated current and generates a high temperature of 300 ° C ~ 500 ° C, posing a safety hazard. The new design of the thermal protection wirewound fuse of the Celtic can be quickly disconnected at 1.5 times to 2 times the rated current, which is safe and reliable. Source: Electronic Business
led Spot Light is a typical no main light, no fixed size of a modern genres lighting, interior lighting can create the atmosphere, if a row of small Led Spot Light combine light energy changes fantastic patterns. Due to the small Spot Light can freely change the angle, the effect of a combination of lighting is also changing,like dim to warm par light. Spot light, soft, elegant, led Spot Light can also be local lighting, heighten the atmosphere.
Features:
Led Spot Light can be placed around the ceiling or the upper furniture, can also be placed in the wall, skirt or skirting. Light directly on the need to emphasize the objects on the home to highlight the subjective aesthetic effect, to highlight the unique environment, rich layers, the atmosphere rich, colorful artistic effect. led Spot Light soft, elegant, can play a leading role in the overall lighting, but also local lighting, contrast atmosphere.
Led Spot Light Function:
1) Save energy: The same power LED lamp power consumption is only 10% of incandescent, but also energy than fluorescent.
2) Long life span: LED lamp beads can work 50,000 hours, than fluorescent lamps and incandescent lamps are long.
3) Dimmable: Previous dimmers have been for incandescent, incandescent light dimming red; difficult to see fluorescent dimmers, which is dimming technology for many years did not develop the main reason; now the LED can dim , And whether it is light or dark light is the same color (color temperature basically unchanged), which is significantly better than incandescent dimming.
4) Low calorific value: Like led Spot Light, a lot of 220V spot with a few days is not broken because of fever. 12V halogen spotlights, although the heat is lower than the 220V spotlights, but there are due to lack of power and other reasons with the transformer, the brightness of less than the nominal value. With LED lighting, no transformer can work for a long time.
