| Long light LED street / lighting performance The patent lens (Lens) design package, the maximum strength up to ± 55 degrees above, to substantially reduce the light loss, getting the rectangular spot, so that the LED street lamp / lamp irradiation uniformity achieves Emin/ Eavg > 0.5. The shelter design, about 80 ~ 90 of lead angle at extremely low light intensity, thus effectively prevent glare. The light source and the power part adopts the design of closed waterproof and dustproof, protection class IP66. The front cover part of the light transmittance of >93% toughened glass, can enhance the lighting efficiency. Using constant current driving type switching power supply, the input voltage from 90 to 264VAC wide range, power conversion efficiency of more than 90%. Light source and power supply adopts split design, easy maintenance. Start time is short, not flash frequency. Advanced matrix wiring production without solder joint process, avoid the individual LED lamp bead damage caused other lamp does not light or for other lamp current increase and burn other beads the vicious spiral phenomenon, and enhance the cooling effect. Operating temperature range (-45 ° C to 50 ° C). Environmental protection, safety, no pollution, meets RoHS specifications. The unique patented design of cooling plate with aluminum plate heat, high coefficient of heat transfer, and welding of aluminum fins and heat pipe at the back, using heat pipe heat conduction ability of super fast, using the principle of aluminum fin area and air convection cooling, let LED junction temperature maintained at 75 ° C below, and to ensure that the temperature difference between the LED light source of copper base the control to the radiator at 5 ℃. |
