Since 2011, LED lighting products have flooded into circulation channels, and sales have gradually sunk to counties, towns, and villages. They have been widely used and accepted by the public. However, there are still some misunderstandings about the use and understanding of LED lighting products.
Not long ago, an activity explored the topic of "LED era, are you still pursuing power?", at the time, I thought that this kind of problem does not need to be discussed at all. Anyone who knows the lighting must understand it. However, a phone call from a dealer partner who had cooperated for more than 10 years ago woke me up. He asked me why our LED bulbs are marked with 7W power and the measured value is only 6.5W. The traditional lamp era standard is based on the nominal power. Poor, why is there a difference in the nominal power of the current LED products? I explained: First, this power difference is within the nominal range of the national standard; second, consumers pay for the light, we are now pursuing It's light, not power.
Later, I learned that he called because the salesmen of some small factories went to him to promote the products with the power meter. It can be seen that the market competition is indeed more intense. However, they use this kind of promotion or because their products are low-light effect. In fact, this indicator of the quality of the lamp itself is not right.
In the LED era, different manufacturers use different chips and different package forms to achieve completely different light effects. Different drivers will also have different conversion efficiencies. The LED lighting effect is mainly determined by the following three factors: First, the luminous efficiency of the chip and lamp bead used; Second, the conversion efficiency of the driver used; Third, the light transmittance of the lamp body cover/PC cover. These three points are important factors that ultimately determine the overall lighting efficiency.
According to the law of conservation of energy, the higher the conversion efficiency of electric energy to light energy, the smaller the amount of electricity that reaches the same luminous flux, and the more energy-saving. A variety of sales practices have caused confusion for businesses, but we must be clear that consumers spend money on light, not power; consumers of the same power make higher light, consumers are the ultimate beneficiaries.
Since the relevant national standards have not yet been formulated, it is difficult to avoid certain confusion during the period of rapid development of the industry. However, when the country sets standards in the future, should we weaken the power indicators and strengthen the light-passing indicators? Only in this way can we guarantee consumer rights and guide the correct consumption direction.
