LED lights in the application environment in Coldon June 28th, 2012 at 6:55 AM
With the rapid development of LED Power Supply 100w lighting technology, many cities in the country, roads, lighting has been no shortage of LED lights figure. Especially the luminous efficiency of high-power LED devices than 100lm / W, 100w LED Power lights as the development trend of road lighting has been generally recognized. In 2009, several cities were organized assessment testing of LED lighting products, most of the LED Floodlight 20w lamp products made ??significant progress in the key technical indicators of the distribution curve, the system luminous efficiency, road lighting standards compliance, energy-saving effect other aspects meet the relevant standards and regulatory requirements.
Although the level of development of 30w LED lamp technology is faster, but most of the LED lamp manufacturers in the product development process ignores the special technical requirements in the environment of cold applied. A common mistake: the LED in the cold regions conducive to heat dissipation, and less prone to failure. As everyone knows, the cold environment, the LED flexible strip 5050(m/60lights) lights with the more stringent technical requirements, there are the following two aspects:
1, cold regions the temperature is low and the temperature difference between the hot and cold impact of sudden changes and long-term low temperature for the devices have more stringent quality requirements;
2，LED street lamp in cold regions must take into account the precautionary measures to prevent ice condensation.
