High-Pressure Sodium (HPS) lights have remained a popular street lighting solution. Despite their widespread usage, however, HPS lamps display numerous deficiencies, particularly when compared with newer lighting technologies. HPS visibility issues are compounded by its inherent color limitations. High-Pressure Sodium lamps generate narrow spectrum light, which appears to us as a dull yellow glow. Hampered […]
Luminous Flux Luminous flux is the quantity of the energy of the light emitted per second in all directions. The unit of luminous flux is lumen (lm). One lumen is the luminous flux of the uniform point light source that has luminous intensity of 1 candela and is contained in one unit of spatial angle (or 1 […]
Street lights use highly inefficient HID lamps that drain the grid of electricity and cost untold millions of dollars a year to power and maintain. Obviously street lights are needed for the safety of travelers at night, but why does so much money need to be wasted by powering these inefficient old standards of lighting? […]
The LED lamps have a greater lifespan and electrical efficiency that is many times better than the conventional lighting system. Beside this, LED lights are significantly much better than the most fluorescent lamps as well. Solar powered LED light has just left everyone speechless in order to compete with solar lighting system. Below is difference between […]
Solar street lights consist of four main parts: solar panel lighting fixture rechargeable battery pole There are two types of solar LED lights according to design structure. Traditional solar street lights feature panels, fixtures and accessories that are wired together. Second generation all-in-one solar street lights integrate the solar panel, LED source, PIR motion sensor, die casting […]
