About Us
In the past two years, LED street lights have been widely discussed since there exists a very large market and the LED’s power saving performance is obvious especially in replacing the 250 W or 400W mercury lamp.
Vision
To build an LED street light, the key issue is needed to reach and meet a specific specification, for example, it needs to guarantee 5 years (since everyone knows LED life is 50,000 hours), the light pattern has a specific request to meet the roadway regulation specification, dust and water-resistant has to reach IP65, mechanism strength needs to be enough, etc.
Mission
Based on these requests, to design the LED street light, one needs to consider the thermal, optical, power and mechanism. LED life depends on the LED junction temperature (Figure 1). Cree has announced data to show the relationship of life versus light maintenance for different junction temperatures
