SOTEC-Cosmo Street Lighting

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.

. 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.
● One electronic ballast, measurement and weight even less than half of magnetic inductive ballast system.
● More choice for reflector and lighting fixture, higher light efficiency.

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:
CDM-T: 2 years
CDO-TT: 3 year, lumen maintenance 60%
HPL: 3 year, lumen maintenance 60%
SON PIA: > 4 years

● CosmoPolis HID-PV EXtreme electronic ballast: 60,000 hours, only 5%lost.

Complete sealed construction, dust-proof, water-proof, shock-proof
Peak Voltage protecting. Protect light source,, anti-inrush current, protect ballast.
High efficiency system, energy saving and environmental protection.
Power factor:0.98 no worry about compensation of capacitance.
Constant power output, no affect by power voltage fluctuations (Voltage: 200~254V, power:+/-2%).
Complete lightning protection, meet EMC/EMI standard.

5. Constant power output

● May choose smaller cables
● May less use the control cabinet

6. Natural white light

● Natural light highlight the surroundings create more vivid and attractive night environment.
● Improve the sense of security give people comfortable natural and safety feeling.
● Making driving safer: white light can help drivers better distinguish the environment around and roadblock.

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.

 . 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.

. 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.
