Sharp Corporation has developed a new line-up of ten LED-based outdoor lighting products and will introduce them in succession into the Japanese market over the coming months. In addition to four solar-powered LED lights that combine solar panels with newly developed high-intensity, long-life LEDs to achieve industry-leading brightness*1 (instrument-measured luminous flux = 1,800 lumens), there are two models of LED security (crime deterrence) lights and four LED lighting fixtures.
Solar-powered LED lights provide exterior illumination while emitting no CO2 whatsoever. They work by storing electricity generated from sunlight during the day in storage batteries to provide LED light at night. Since October 2005, Sharp has been working to reduce the negative environmental impact of outdoor lighting by deploying these lights around schools, public parks, and commercial establishments.
The four solar-powered LED lights feature newly developed LEDs with 30% higher luminous efficiency*2 and a newly developed LED lens designed to spread this light over a broad area. As a result, they achieve brightness at one of the industry’s highest levels and can flood a wide space with light. This level of brightness also significantly lengthens the installation interval to 32 m (for model LN-LX1; compared to 12 m for 40-W mercury-vapor lamps) and reduces the number of units that must be installed to meet Class B recommended standards*3 for crime deterrence lighting. The result is reduced CO2 emissions and lower costs.
In addition to the four solar-powered models, the new line-up features two LED security lights that come without poles and four LED lighting fixtures capable of illuminating a wide area from a pole height of 4.5 m.
Sharp will be working proactively toward providing “LED lighting for the whole community” by meeting the various needs of customers for environmentally friendly and economical lighting.

Compared to Sharp model LN-LW3A1. |
| *3 |
Based on Outdoor Lighting Standards for Public Pedestrian Areas, published by the Japan Security Systems Association. Class B is the level of brightness that will enable an individual to judge the behavior and/or posture of a person from four meters away. Installation interval for lighting fixtures must be such that the average horizontal illuminance is at least 3 lux, and minimum vertical illuminance is at least 0.5 lux. |
| *4 |
Salt corrosion resistant. Applicable for use under sea winds as long as the lighting system does not come into direct contact with salt water. |
