Now the manufacturers are actually not easy. On the one hand, they have to deal with the fierce competition of their peers. On the other hand, they have to face the control of commercial channels. An industry insider feels emotional. Today's social awareness of LED lighting is continuously improving, and how to better promote and apply LED lighting products has become a problem facing and thinking in the whole industry. At present, because the engineering company controls the engineering channel to a large extent, it often sees how the engineering company wants to do it, and if there is no assessment of product quality, it can only fight the price. An industry insider said that under such circumstances, if manufacturers pursue high-quality products, they may die very ugly, because high quality is often accompanied by high prices, the chances of being selected by the engineering firm are also reduced. In this regard, Rong haolei, the director of Tsinghua Tongheng Institute, believes that from the perspective of the market chain, if the information is asymmetrical and the power is too concentrated in a certain link, it will be a kind of suppression to the market, and it is more likely to be devastating. Therefore, the choice of products should be transparent. At the same time, the consideration of the product should also be the same. Parameters are one of the aspects. Brand value, product quality and application effect should be taken into consideration and only the correct one should be selected. From the perspective of design, we hope that we can stand on the position of the owner, make the value relatively transparent, analyze and display the lighting value. Rong haolei said that LED lighting products are different from traditional light sources. Even with the same parameters, such as the same beam angle and power, the effects vary greatly under the same installation conditions, as a designer, you must make the effect, otherwise you may be accused of design failure. In the Internet era, the important competitiveness is credibility. LED lighting products cannot be promoted to promote products, but should be promoted to establish a good reputation. Rong haolei believes that LED lighting products can avoid favorable advance, but should continuously verify the products in application by conveying the real situation.
