SHARP LED outdoor lighting power consumption and fluorescent lamp the same

SHARP was held in August 30, 2007 by the combination of solar cells and white LED lighting outdoor lighting "LN-LW3A1/LN-LS2A" product description. The outdoor light was released by SHARP in July 17, 2007 and began to supply in August 21st. Bright light is 1800lm (LN-LW3A1), about 6 times the company's original product, "in the use of solar powered LED lighting for the industry's highest level" (SHARP).

The same as the brightness and power consumption, the use of 32W fluorescent light source outdoor lighting is roughly the same. Powered by solar cells, without special wiring power supply. SHARP projections, compared with the outdoor light driven by the power supply, 153.3kWh power consumption and 48.2kg emissions per year can be reduced by CO2. The service life of the light source is about 40 thousand hours (brightness down to the initial 70%), so it is more convenient to maintain the outdoor light than the fluorescent lamp with a service life of about 5000 hours (LED). SHARP said that the use of fluorescent lamps, 10 years must be replaced by about 5 times the light source (daily lighting for 12 hours), and the outdoor lighting can be replaced within about 10 years without replacement.

The product will be put on the domestic market. SHARP said that Japan has about 12 million street lamps, each year will be a new 100 thousand. Now, in the new demand, the proportion of products driven by solar cells is currently less than 1% (SHARP). The outdoor lighting has many advantages - do not use the power supply, it will not emit CO2, even if the earthquake and typhoons and other power outages, can also be used as a lighting, and about 10 years without the need to replace the light source. Therefore, SHARP intends to focus on these advantages of publicity, to seize the new demand market. In the overseas market, although there are customer consultation, but has not yet established the installation and maintenance of the business system, so there is no intention to launch overseas markets (SHARP).

The outdoor lighting, LN-LW3A1 brightness of 1800lm, LN-LS2A brightness of 1200lm. Light source used in the number of white LED, 1800lm products for 756, 1200lm products for the 504. In order to achieve the effect of sunlight as the sun, the white LED with a color temperature of up to 6800K day white products. Equipped with solar cells, 1800lm products for the 80W 2, and 1200lm products for the block of 1. The electricity generated by solar cells is stored in the lead battery. 1800lm products are equipped with 5 battery capacity of 38Ah lead battery, 1200lm products are equipped with 3. After full charge, even if there is no sunlight for a week, can also work as usual (7 hours a day for full power lighting, the remaining time for energy-saving lighting). Equipped with a sensor, after the detection of the 5 earthquake, continuous power lighting can be carried out within 2 days.
