Application in domestic 1) Tunnel
2) Manufactory 3) Main Street 30% Energy Saving Compared With LED The newest generation of revolutionary outdoor lighting, saving about 30% than LED light, cost about half of LED light. It with the feature of high color rendering of white light, significant energy saving effect, in the outdoor lighting field will leading new trend. Have the Honor to win the awards of "best light source and electrical award" which is the prestigious British industry lighting design awards, the judges praised Cosmopolis road lighting is the model of "Generation update". Initial cosmo street light succeed to the quality of German lighting, opened a new chapter of Low carbon, energy saving, and environmental protection in the field of street lighting in the 21 century. cosmo light has the newest technology in street lighting. Including the complete system, Its Cosmopolis light source has advantage over high pressure sodium light and metal halide light. Also it has long life outdoor applied electronic ballast and lighting fixture which has special reflector for Cosmo light. Refer to home and abroad cases, all Cosmo lighting have good effect in both lighting and energy saving. Generally speaking,140W Cosmo light can instead of 250W high pressure sodium light, use in most cities and all kinds of road. Its illumination, brightness, and uniformity of light all meet lighting standard. Further more, it gives much more comfortable light and visual resolution than high pressure sodium light. Ⅰ. Advantage of SOTEC Cosmo lighting 1. Highly efficient, energy saving The highest lighting efficiency may reach to 118lm/w, 140W Cosmo light system can replace normal 250W high pressure sodium light. 2. Small size and light weight ● The measurement of COSMO
light source is half of HPS lamp. 3. Best optical efficiency ● Perfect proportion in tube diameter and length (A.R.), best light distribution Spacing height ratio is 12~15% higher than normal street light, can use less light and shorter light pole, so that can save investment. 4. Long life time ● Lighting efficiency only lose 10% after 3 years using, lumen maintenance reach 80%. Reference: ● CosmoPolis HID-PV EXtreme electronic ballast: 60,000 hours, only 5%lost. Complete sealed construction,
dust-proof, water-proof, shock-proof 5. Constant power output ● May choose smaller cables 6. Natural white light ● Natural light highlight the
surroundings create more vivid and attractive night environment. SOTEC Cosmo has advantage of highly efficient, energy saving, comfortable visual, and stable lighting effect. It is not only approved theoretically but also in practical application. As a new generation of road lighting system, COSMO energy saving street light will greatly saves energy consumption and initial investment cost as well. Ⅱ. Comparison with LED street light According to the lighting industry development, till now (December, 2010), in practical application of more than 45 Watts high power lighting, LED light can only reach the same level in lighting effect within 3 years compared with SOTEC street light. LED has a long way to go for its products to get mature and price comparable with SOTEC COSMO street light. Summary: At the same lighting effects level (same brightness and lighting width), SOTEC Cosmo street light saves 30% energy consumption compared with LED street light. COSMO light source and electrical equipment cost only half of LED light. Under same energy consumption, LED street light Luminous flux is 30% lower than SOTEC Cosmo street light. Ⅲ. SOTEC·Cosmo products model, specifications and features 1. Light source ● Feature In human eye evolution research, the feature of Cosmo light source's high showing of white color light meet most requirement for natural white light. a. Good Color rendering index and Color distinctiveness Good Color rendering index and Color distinctiveness may help us know the surroundings and road conditions to ensure driving safety and comfort. Compared with sodium light, people trend to like Cosmo white 3000k, while like Fluorescent lamp and Mercury-free sodium lamp least. Light research center of New York shows that driver give slower reaction in yellow light compared with day light. Cosmo light gives nearly same light effect with day light. b. Better visible light Light research center of New York did real test, yellow light compared with Cosmo visible light when people in driving. They found in comparison of vertical illuminance and relative horizontal light distribution, using Cosmo light, the response time of brake and speed is increased. Time for brake even shorter than speed. Target miss rate fell. In Cosmopolis white light, even illuminance fall 58%, the recognition distance still can increase 22%. Average distance for face recognition By the a bov statistics can see face recognition in white light is better.
2.Electronicballast ● Feature a. Light, delicate, outdoor
use of electronic ballast, applicable to the COSMO light source features and
advantages. 3.Lighting fixture ● Material Specifications
a. Lighting fixture material: Body: recyclable high
intensity casting aluminum alloy(National standard ZL102), dark grey texture surface
treatment, surface color is optional b. Specifications: Power Voltage:AC220V 50Hz ● Feature a. The light body is die-casting aluminum, smooth in surface, line is fluent, Compact structure, safe and reliable, innovation design of light fixture structure b. High lighting efficiency c. High safety d. Simple installation and
maintenance e. Long life time, it means no need to replace often. It reduce the potential of traffic disruption, also reduce the maintenance fee of repairing it. Electric board design is universal for Cosmo electronic ballast, Ceramic metal halide electronic ballast, and 150W/250W Sodium light electronic ballast , two male and female connectors connect to line in and line out. |
