From the traditional light source to the LED, how many times have you experienced the changes and upgrades of the light source? This article will introduce the efficacy of the traditional light source, the efficacy, advantages, and disadvantages of the LED light source. 1.The light efficiency of traditional light sourcesFirst of all, one light input
“Advisory sales” was proposed, requiring the lighting industry sales technology not to be as versatile as the designer, at least should be more professional than the customer, can solve most of the problems of the owners, but in fact, we do in this regard still not enough, for example: Usually we often hear questions from
Recently, some novices have asked:” can we see the color temperature in the IES file? The answers from friends are also varied. Some people say yes, some people say no, it can be said that they have each word, and they are arguing endlessly. Then what is the right answer? It is OK or not?
The higher the LED light efficiency, the lower the Color Rendering Index? It is obvious that this view is not right. Firstly, this causal relationship of this logic is somewhat reversed, it is not because light efficiency is low and therefore CRI is high, but in order to improve CRI it sacrifices some light efficiency.
