Development Space Of LED Light Source

Development space of LED light source

Compared with traditional light sources, it is not difficult to see the advantages of LED. To a certain extent, LED can replace incandescent lamps for general lighting. After all, the luminous efficiency and service life are much higher than the latter; But strictly speaking, LED has not completely replaced traditional light sources, such as incandescent lamps and fluorescent lamps.

There are several reasons:

① too much one-time investment;

② the manufacturing standards of light sources and lamps are not unified;

③ test and evaluation methods are not unified;

④ heat dissipation and optical structure are not fully mature.

As a newly developed light source, it is bound to be accompanied by many new technologies and materials; And the output has not expanded. In this way, the cost of LED is relatively high. When there is a breakthrough in technology and the output is significantly increased, the cost of LED light source is bound to decline; Similarly, emerging products do not have complete manufacturing, testing and evaluation standards, which is also a bottleneck in the development stage of LED. At present, standards are being actively prepared at home and abroad. Many drafts have been issued, and the relevant standards for LED will be complete in the next few years; For technical reasons, LED is developing too fast, and the corresponding heat dissipation and optical processing are also following up, but they are not fully adapted. With the progress of LED technology, heat dissipation and optical processing are about to be solved and finalized.
