LED lighting improve color rendering index scheme 2

Current white LED technology, mainly adopts blue chip phosphor powder coating process, the technology developed by day and the company, from a certain extent with fluorescent tube light-emitting principle of this technology due to the lack of the composition of red light and green light, to make it on there is a congenital defect of insufficient color rendering index, to make up for the defects at present, phosphor technology has become a main direction in the industry.

Blue chip coated with phosphor powder manufacturing white light, this technique can be produced on the principle of white light with better effect, but in the use process due to the weak adaptability to the environment, cause the difference between theory and actual product, the difference is largely because of the LED heat accumulated temperature on the influence of the phosphor powder.

We all have such experience, high power white LED as work time, heat production and heat loss gradually achieve the equilibrium, the equilibrium temperature is higher, to use the same type of phosphor white LED the greater impact.
