After the magnetic gap is padded with appropriate padding, stick it with adhesive and wrap it with high temperature resistant and flame retardant adhesive tape to prevent it from becoming loose. In addition, do not connect the same end of B incorrectly. Maintenance of the electronic ballast using the trigger tube, should focus on checking the bidirectional trigger diode, this tube generally uses DB3 type, its bidirectional breakdown voltage is 32±4V. In terms of technology, LED lamps and ordinary energy-saving lamps, each have advantages, in a certain period of time, should not replace energy-saving lamps; However, the cost of LED lamp will decrease with the continuous improvement of LED technology.
The movement of the cavity is reversed. So near the PN junction, just to the side of the P region, the electrons in the high energy state meet the hole, and the radiation energy is expressed in the form of light, which we see the light emitted by the LED. In the past, LED lighting was mainly used for architectural landscape lighting, such as Path light, Floodlight, Step lights, balcony lights, etc., accounting for about 43% of the overall LED lighting market in 2008, but the growth of this field has been slow.

Merchants are using the slogan of energy saving, but shoddy, consuming people’s trust in LED lights. So should we lose faith in leds? The answer is no! The National Development and Reform Commission has announced that the import and sale of incandescent lamps will be gradually banned by power level in October 2012. The emergence of LED lights in the history of lighting has a milestone significance, it has the advantages of energy saving, soft light, easy recycling and recycling.
Looking back in history, the rise of our LED display industry is also related to international sports events. Beijing, as the “City of Double Olympics”, LED display has also been entrusted to reuse in the opening ceremony of the two Olympic Games and urban construction. In the opening ceremony of the 2008 Beijing Olympic Games, the huge LED screen scroll of 6,000 square meters and the dream five rings carrying more than 40,000 LED light beads amazed the world.
Failure analysis of LED lamps, Now LED lighting market prices are all over the place, the quality is uneven, many reasons is in the Chinese market, manufacturers of patent awareness is not strong, lack of innovation, LED lighting appearance, structure is the same, the industry price war leads to manufacturers constantly in the material selection, production process and other aspects to reduce costs, which makes LED lamps often appear large quantities of LED failure phenomenon.
