led smd and led heat sink

Using LED high bay brightness lighting requirements using manufacturers allow maximum current drive, but the average life expectancy of LEDs is highly dependent on temperature. Operating temperature rose by only 10 ° C can make life shortened by half. This situation forced designers to adjust the current must be reduced, sacrificing brightness to extend the service life. If required LED working under high ambient temperatures, the need to further reduce the current to minimize the environment to...Continue reading

battery powered led lights in 2013

In the past about 150 years, the lighting industry has developed into a large-scale production industry based on standardized bulb, lamp design has inherent outdated. Consumers find themselves often use the same new products to replace short-lived in the product. This trend with a small number of large manufacturers are inseparable, they are through to the hundreds of millions of low-cost manufacturing of a product to meet the needs of the market.

More than 80% failure of LED products is from LED power suppliers

LED lighting market is fast growing, along with the rapid development of LED lighting industry. On one side, manufacturers for traditional light power supplies aggressively introduced new LED power suppliers or upgraded products for LED lights. On the other side, man entrepreneurial companies have been founded as well. However, the power technology is not mature yet. There is still no unified standard and the corresponding market is also in chaos. Relevant experts believe that LED lighting marke...Continue reading

LED test: errors frequently happened

Usually, in LED test, luminous flux, CRI, color temperature and power deviation are four major aspects that with relatively high failure rates. Unqualified quality testing results mainly concentrate in four aspects: 1. Electrical insulation cannot meet the corresponding requirements: insufficient internal clearance and creepage distance, with touchable conductors (not safely isolated). Especially for some small sized LED lamps, the compact structure forced manufacturers to ignore the requirement...Continue reading

Reasonable prices will contribute to the popularization of LED garden lights

We can find a variety of garden lights in the market, with all sorts of styles and light sources. Some of them are cheap but with poor quality conditions, some of them have good performances and qualities but really expensive.
