New Street lights Enable to Save Approximately 60% of Energy in Chinatown, Los AngelesBack
Five streets in Chinatown refurbished its road lighting and upgraded the light points to modern, energy-saving LED technology. Approximately 2,000 LED street light retrofits sourced from SANSI were installed to replace old ones. This enables the city to save approximately 60% of energy compared to the old system.
Chinatown is a neighborhood in Downtown Los Angeles, California that became a commercial center for Chinese and other Asian businesses in Central Los Angeles in 1938. The area includes restaurants, shops and art galleries, etc. Around 2,000 LED street light retrofits from SANSI were installed to replace old ones throughout the complete urban area.
The old lighting system was operated with obsolete and inefficient light sources. There was also no possibility of controlling lighting according to needs: to save energy, every second luminaire was switched off in some sections each night, causing hazardous dark zones. With the new LED street light retrofit solution, not only the quality of light was significantly improved but the city also now saves approximately 60% of energy and CO2.
The new LED street light retrofit lamps feature significantly longer lives of up to 50,000 hours, meaning that maintenance and repair costs are reduced in turn. In order to exploit the savings potential of LED technology as far as possible, all luminaires were equipped with SANSI self-produced intelligent control system. The light management system enables single luminaires and also complete luminaire groups to be controlled according to requirements and centrally monitored.
The project employed SANSI C21LP-N LED light retrofit, the product features
SANSI LED street light retrofit benefits:
♦ Composed of high quality aluminum
♦ IP65 protection for hash outdoor environments
♦ High luminous efficiency based on high power imported LED chip
♦ AC85 ~ 264V wide input voltage range
♦ Operating Temp -40℃ ~ +55℃
Optics with the Light Flux Ray Method (LFR)
Using reversed optical designs and software, we simulate the optical parameters of the coverage area to calculate the lens model. Optical technology ensures that 93% of the light emitted is contained within the customized beam angle. SANSI optic lenses prevent optical loss and uniformed light distribution.
Light Distribution Customization
SANSI offers a variety of optical lenses suitable for various road conditions providing uniformed light distribution.
Brighter light for every street: SANSI LED street light retrofit
With significantly higher light output and a visibly more attractive light appearance, new street lights now replace the old 250, 150 and 70 W HQL or SON luminaires all over Chinatown extremely efficiently and very effectively. To ensure the best possible light quality for any location – such as footpaths, main roads – all luminaires are equipped with optimum optics.
The client was very satisfied with the results of the LED street light retrofit project in cooperation with SANSI: “With five streets in Chinatown we have taken a first step toward being a smart city. The dynamic light offers maximum road safety with minimum energy consumption. Thanks to the smart system, we were able to achieve additional energy savings of 60% compared to a standard LED solution. Implementation was quick and smooth thanks to the perfect support offered by SANSI. In the next two years, we would like to replace 40, 000 traditional LED lights with SANSI LED street light retrofits in the whole downtown .”
SANSI will supply a total of 40,000 LED street light retrofits for Los Angeles in the next two years. In addition, SANSI will launch an up-grated ceramic LED street light retrofit. We aim to develop innovative outdoor LED lighting solutions that improve and enhance people’s lives and to provide systems that increase the livability and connectivity of our outdoor environment.
