In the opening speech of the forum report, the Ministry of Science and Technology Vice Minister Cao Jianlin also announced the national goal of “12” dimmable LED downlight plan: by 2015, LED industry luminous efficiency of lumens to 150 lumens / watt, R and D level200 lumens / W, life expectancy of 50,000 hours, the market reached 500 billion yuan; semiconductor lighting innovative applications, product development, systems solutions to reach the world advanced level, the establishment of the joint Laboratory of the world-class, and the least contribution to the 2international standards.

 

The dimmable LED downlight industry is currently high price of existing product, awareness is low, the original interest in the chain resistance and other issues. Guangdong to establish a joint conference system in the province, the relevant departments jointly organized and implemented the “thousand million” high-power LED high bay light industrialization demonstration and extension projects and green lighting model city special action. Canton (state) music (Chang), Bo (Law) deep (Shenzhen), the new highway LED lighting demonstration project construction has started, the province install LED street lamp over 260,000, more than 2500 kilometers of the demonstration sections, the scale and progress among the country.

 

First, develop the market. The present situation, the domestic LED display market to some extent has reached a mature stage, the lighting market is not yet fully grown up, we all know, LED real space is in the lighting market. “12 Five” is the critical period of development of LED lighting market, whether open also depends on the development of this period, the domestic LED. Thus, the cultivation of the market is particularly important.

 

 

Lighting controller to the line dimming or secondary side of the dimming way to work. The simple line dimming the forefront of SCR controller. This is the most commonly used lighting control, but unfortunately, the use of SCR controller when the dimming of the dimmable led downlight produce a large number of problems. Flexible programmable control functions can be controlled step-down pressure limiting magnitude, the light switch time arbitrarily set. Control mode and sometimes control, light control, manual control, PC remote control and location according to latitude and longitude of automatic control. Soft start, soft transition, the soft-off function to prevent the impact of voltage and cold start current of the lamps, significantly reducing the damage rate of the lamps. Preheat start time, dimmable led downlight, mercury lamps with adjustable lighting can be more fully warm-up, a smooth transition to the normal working condition.

 

To achieve control of the whole dimmable led downlight, and there late at night and then step-down to adjust the flow function, the energy saving effect is more ideal. The perfect re-start function when the load fault, the end of the external power supply failure, automatically re-lit lamps. Control mode and sometimes control, light control, manual control, PC remote control previously used on led high bay and automatic control according to the latitude and longitude of the place of use (optional). Three-phase light switch time and the output voltage can be adjusted independently, which can be accessed imbalances and different types of load. Programmable mode of maintenance, ease of maintenance of lighting systems, maintenance and lamp replacement. Reserved for the normally open contacts of a group of control by the clock in order to achieve a special control. Contact capacity 7A/250VAC.

 

 

 

Several dealers said that the profits are not high sales of LED energy saving lamps, generally only about 10 percent of the family of 8-watt LED lights only ex-factory price of 35 yuan. So, what factors led to the high price of dimmable led downlight In this regard, specially came to the professional production of LED energy saving lights Electric Co., Ltd. of Hebei Long right to visits.

 

In a 600 square meters of production workshop, Liu and more than 50 other workers sitting in the parts of the conveyor belts, hands skilled assembly proceed orderly. Liu introduced a small energy-saving lamps looked at the structure is very simple, but it must be more than 20 process, if a process is not rigorous, it may cause the lamp is not lit.

 

Liu’s work is a cob, green beans the size of the lamp beads into the predetermined mold, the mold needs a total of 37 lamp beads is an essential part of about a 2-watt dimmable led downlight. Liu will be inserted to the good parts into conveyor belt, and quickly picked up by the next person, exposed to the metal line cutting, welding, and then sent to plug the power supply board at the conveyor belt, after which they tested , welding leads, the combination of detection, aging test, a road process, a small LED energy-saving lamps can produce.

 

Lines more than 50 workers a day can produce more than 10,000 led high bay. However, although the yield big profits are not high.

 

Wu Zhanbing come up with a 20 watt LED energy-saving lamps, the only light a total of 330 lights bead composition.

I am a strange girl from childhood was also regarded as a genius, no survival of the target in addition to the development of my genius. However, when the childhood fantasygradually faded, I found that I have nothing – only a
