LatticeLighting has succeed in developing and manufacturing high power LED street light and tunnel light with demonstration of luminous efficiency of 108.6 lm/w. It is the commercially reported highest luminous efficiency LED Street light in the world market.
Luminous efficiency, i.e. lumens per watt, is one of the most important technical parameters for judging the quality of a LED light. It symbolizes the feature of energy-saving of a light: the Higher the luminous efficiency, the better the LED light.
High power LED Street light and tunnel light developed by LatticeLighting are featured with high performance chips of average luminous efficiency 125lm/w. The test results of LatticeLighting LLRA120 by China National Lighting Fitting Quality Supervision Testing Centre showed the light features as follows:
Total luminous flux: 13 395 lm
Luminaire efficiency: 108.6 lm/w.
The successful development and manufacture of this LED light demonstrated that LatticeLighting’s independent technology for street light and tunnel light has ranked among the most advanced LED technologies in the world.
The advantages and key features of LatticeLighting outdoor lights are as follows:
1. Modular design: pluggable modules for easy exchange and maintenance
2. Heat Dissipation: the heat can be easily taken away by airflow through the pre-designed gap between modules
3. Optical Design: excellent quadratic light distribution and illuminance, with illumination uniformity over 0.8.
4. System Luminous Efficacy: Luminaire luminous efficacy of more than 80% has been achieved. The result of recent testing on LLRA120 street light by China National Lighting Fitting Quality Supervision Testing Centre has showed a system luminous efficacy of 108 lm/W.
