Light how much would be enough? The required amount of light is usually determined by the environment and uses. The conference room, the lighting in the general round table may be very bright; but if the projection system to watch the conference materials, conference room light may dim; living room lighting will normally be adjusted […] ↓ Read the rest of this entry…
First, select what kind of LED lamp. This is very important, the quality of the LED flood light 50w lamp beads is a very important factor. Some examples, the same wafer 14mil white segment chip to do with ordinary epoxy bottom glue with white glue and packaging glue package out of the LED lamp, a […] ↓ Read the rest of this entry…
However, in order to different everyday lighting applications, also for the luminous efficiency of light-shaped, thermal design and the overall use of cost and number of applications continued to improve the design of LED flood light products, LED lighting is more practical value, rather than just show the environmental demands of the decorations. 80W high […] ↓ Read the rest of this entry…
Since 2009, China LED lighting industry set off a wave of investment upsurge, continued until the end of 2011. Data display, training time in the2009-2010 between Chinese LED chip project for a total of 46, has not been put into production of project of up to 16, accounting for the total number of projects amounted […] ↓ Read the rest of this entry…
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.
