You may find LED street lights are more and more popular. Why LED street lights replace HPS street lights step by step? Following points are main reason.

1. Color Rendering Index

CRI of HPS street lights are less than 50. Color of object is faith, boring and hypnosis.

CRI of LED street lights are over 80. The color of object is fresh, veritable and comfortable.

2. Color Temperature

Color temperature of HPS street lights is usually less than 3500K. It’s yellow or Amber. It’s uncomfortable.

Color temperature of LED street lights can be 2700-7000K. It looks comfortable.

3. Lifespan

Lifespan of HPS lamps is usually less than 10,000 hours. Lifespan of LED lamps is 50,000 hours.

Because technology of LED improved, effiency of LED became higher and higher. Price became lower and lower. Many customers accpet our LED products. Our LED street lights, LED flood lights, LED industrial lights and LED strips are popular in many countries.

Initial effiency of our products is over 100lm/w. Maintain effiency of our products is over 80lm/w. So, they are widely used to replace incandescent, high pressure sodium, mercury and halogen lamps.

Because of energy saving, price of solar kits for LED lights is much lower. So, solar LED lights are accept in many projects.

Technology of solar and LED improved fast. Thereby, we believe solar LED lights will be a big wave in the next 3 years. We publish our solar street lights and solar flood lights. In the furture, we will publish more solar LED lighting products for our partners and customers.

More Energy Efficient-Be the Environmental Solution
LUXEON power light sources are more efficient than incandescent and most halogen light sources. White LUXEON today delivers more than 20 lumens per Watt, and is predicted to achieve greater than 50 lumens per Watt by 2005. When viewing solid state lighting as an alternative, it is important to consider the total system level benefits. For example, due to the decrease in energy used for the lighting of a building, air handling costs drop, generating both additional initial and ongoing investment savings. Additional benefits such as the directionality of light for general lighting and vivid true colors without the need for filters in signaling applications add to the energy efficiency on a system level.

Light Emitting Diodes (LEDs) contain solidstate technology made in Silicon Valley using similar technologies that are used in the latest microprocessors. These solidstate devices have no moving parts, no fragile glass environments, no mercury, no toxic gasses, and no fila ment. There is nothing to break, rupture, shatter, leak, or contaminate.

Do you know what is highest efficacy in LED industry?

CREE has reported its industry-best R&D results of 161 lm per watt for a white high power LED.

CREE confirmed that the 1 mm by 1 mm LED produced 173 lumens of light output and achieved 161 lumens per watt efficacy at a color temperature of 4,689 K. The tests were conducted under standard LED test conditions at a drive current of 350 mA, at room temperature.

Therefore, luminous efficiency is 12-15 times than incandescent bulbs. We believe LED lighting period are coming.

Today I read white paper from Philips about performance of street lights. The light sources are LED, High Pressure Sodium and Mercury Vapor. The datasheet is as follow:

I am not sure when they test these. It may be Auguest, 2008. From the above data, we can find the following results. (more…)
