At present, LED lighting technology matures, high-power LED street lights source has reached the efficacy of 80lm / W or more, making the city street lighting energy saving possible. LED lamps, especially high-power LED lamps, is the rapid speed of the impact of the traditional street market.
As the name suggests high-power LED lamps is greater than the power of 30 watts or more, using a new type of semiconductor LED light source. At present, LED street lamp standards are generally surface illumination uniformity (uniformity of road surfaceilluminance) of the average intensity of 0.48. Spot ratio of 1:2, in line with the illumination of the road. (Actually 1 / 2 center spot to reach 25LUX, 1 / 4 center light to reach 15LUX, 16 meters from the lowest light 4LUX, overlapping light about 6LUX. Street market lens materials for improved optical materials, transmission ≥ 93% , The temperature -38 - +90 degrees, anti-ultraviolet UV `yellow no change in the rate of 30,000 hours and so on. In the new lighting in the city has a very good prospect. Dimming of the depth of, and the color and other characteristics will not Dimming change. Solar LED lamps refers to the use of silicon solar panels for power supply to the LED lamps.
At present, LED street lamp standards are:
1. Optical conversion efficiency of 17% (amount of solar energy per square 1000W, the actual efficiency for the 170W)
2. At present, the market street lens materials for improved optical materials, transmission ≥ 93%, Temperature -38 - +90 degrees.
3. Lens LED lamps, LED lamps for the lens, for the rectangular spot, the material is PMMA optical materials, transmission ≥ 93%, Temperature -38 - +90 degrees, anti-ultraviolet UV `yellow, and so no change in the rate of 30,000 hours,
4. Road illumination uniformity (uniformity of road surfaceilluminance) of the average intensity of 0.48. Spot ratio of 1:2
5. With the illumination of the road. (Actually 1 / 2 center spot to reach 25LUX, 1 / 4 center light to reach 15LUX, 16 meters from the lowest light 4LUX, overlapping light about 6LUX.
6. New lighting in the city have a very good prospect of application. The dimming of the depth and color and other characteristics will not change as a result of dimming.

Keemun Tea History
Keemun locates in Anhui Province, China. It is namable for its tea.In the middle of the last century, a mistake occurred in China in the manufacture of a specific tea. That tea was KEEMUN.
Until that mistake, this tea had always been processed as a green tea.
An Imperial Army was passing through a specific part of the province of Anhui. It was the area in which Keemun was picked and processed. A high ranking officer needed quarters for his officers to over-night in and the only available space large enough was a tea factory.
The factory was in the process of manufacturing Keemun (Quemon-Mandarin Dialect). The Imperial General Officer threw the tea factory workers out, even though they were in the middle of processing a batch of tea, and took over the factory.
The officers stayed only one night and left the next morning. After they had left, the factory workers hurried back to inspect the tea. Alas, it had been naturally processed into a black tea because it had not been fired to prevent the process.
The tea was cupped by the Tea Factory Master and proclaimed to excellent.
Keemun, from that point on was now processed as a black tea, although some rare and expensive Keemun green tea is still manufactured.
