This system based on a new reflector ensures more than 90 percent light utility rate, and helps lengthen the serviceable life of a lamp by 50 000 hours on an average. A technology of automatic high-speed charging by natural energy is applied to the system. The new lighting system, which needs less investment and operational cost than the existing one, is of significance in enhancing the architectural aesthetic value of city structures with light decorations. |
