Factors affecting LED home quality

At present, there is no unified LED lighting standard in China. In addition, Huaqiangbei is a cottage country. Low-cost LED takes the relationship to the market, and the information obtained by end-users is uneven. This leads to great misunderstandings on the reliability and quality reputation of end-users. Closer to home, several factors affect quality:

1. In fact, the heat dissipation for the domestic power supply cooling part of the basic level is quite, because the LED power supply technology content is nothing more than AC to DC, boost to the buck, and then add a few certified safety circuits, for LED heat dissipation is the main reason is that Lamp beads above, 95% of the companies on the market currently use lamp beads (3528,3014) on the lamp bead, their lamp power is large, plus the lamp beads packaged silica gel and phosphor, the heat will be a In a single bead, heat dissipation cannot be achieved.

2. Luminous angle has been the current market out of the LED to see the bulb light For example, the market is generally the lamp beads are male models, the production process to use lamp beads pasted to the aluminum plate, the lamp beads and the ground vertical In addition, even though the angle of view of the LED is increased by covering the plastic case, the actual light emitting angle is still only 180 degrees. Therefore, its end-users still have a large deviation from their traditional lamps in use.

3. Product Certification Special lamps such as high-pressure lamp, high-pressure light bulb, and high-voltage power supply are introduced in the special market. Although they are cheap in price, they are very harmful because, since they are high pressure, there must be a phenomenon of exposure. This kind of lamp itself has a frequency problem under the impact of utility power. After the energy is converted into light energy, there is interference that directly affects the use of other household appliances, such as mobile phone signals and television. In addition, the lamp beads reduce the service life of the lamp beads under the impact of high voltage. And such situations directly lead to life safety. Therefore, before the product is purchased, it must be checked whether it has passed 3C. If you have UL, CE is better. Is there a frequency hopping phenomenon? Safety and health are still the first.

4. Light fade problems such as the above situation, such as heat, high pressure lamps, SMD lamp beads, especially the heat that directly affects the light bulb light failure. The latest U.S. ENERGY STAR regulations stipulate that only 2% of lamps can be used after 25,000 hours of light decay. There are professional testing instruments. Whether you can go through the LM80 depends on the business investment. If a product is used for 3 months, it is not responsible for the user.
