Low-pressure sodium lamp (LPS)

Brand: Osram

Country: Germany

Life Span: 18,000 Hours 

Main application: Lighting source of solar street light

Features

1. Low temperature increase

2. Light weight

3. Small self-consumption

4. Large power factor

5. It can save the electricity above 70% more than other light sources.

6. The emitted light has a monochromatic yellow color (sodium line 590nm) for high-contrast visibility in mist & fog.

7. Smaller light decline than other source, can be reached 80%~85% luminous flux at the end of the life.

8. High light efficient

For example: 36W LPS system designed and collocated by our company, used in 8m-height road lamp system, the exposure on the ground is 24.5Lux, however, the 85W energy-saving light at the same height only has 4.4Lux.

Applications

It is especially suitable for the solar road light, arterial roads, motorways, locks, tunnel lighting and highland cold special environment situation etc. Solar energy low-pressure sodium lamp system is the best choice of solar lighting field.
