Ural State University Designed New LED Street Lamp

Jan 4, 2011 Ural State University’s scientists have combined a led and a computer fan to create a new lamp, which can work for 50 000 hours, expecting to provide more efficient than a general street light.

In common led lamps diodes get very hot, and they are usually placed on a significant distance from each other. The system of heat regulation allowed making smaller lamps, thus saving materials. Therefore, compared with common street lamp, this new lamp can supply much more cost-effective.

The problem with this and others is poor engineering- Heat damage is not well mitigated by devices like fans.
Have you ever looked at the back of a average fan ? Debris or insects ( dead/alive)the garbage, dust and the fans
units MTbf - A fan, you've got Leds that endure the consquences of thermal issues ie ; Phosphor bubbles
and to the rescue comes a little fan? Does the fan have its own warranty - Its poor design for the long term!

Is this an optimists streetlight,I didn't hear of critical flaw testing - it seems like a problem in waiting!
If/when the fan fails, or if airflow is impinged the unit lasts how long/ Its like jumpin out of a plane
with a large umbrella instead of a parachute. My local municipality is installing Led street lights-
hopefully made better then this!
