LED enters the new market and the application field is expanding. It has been widely used in traffic lights, display screens, landscape lighting and decorative lighting. The market share in the backlight industry has gradually increased. Many companies that used to work on traditional light sources have also launched LED projects. Industrial investment continued to heat up, and the light efficiency record was repeatedly refreshed. Recently, Cree Corporation of the United States announced that its white light power LED light efficiency has once again reached the highest record in the industry. The laboratory parameters have reached 231 lm/W, compared with 100 lm/W of white LEDs announced by Japan Nichia Chemical in June 2006. The effectiveness has more than doubled, and it is believed that the record will be broken as technology advances.
With the concept of light effect being used in LED lamps, many LED lamps have also been added to the torrent of light-effect competitions. Manufacturers are ignoring the differences in product functions between LED light sources and LED lamps, and only use light effects as a benchmark for lamp performance. Simply pursuing high-efficiency indicators, ignoring the characteristics of reliability, color quality and visual comfort that LED lamps should satisfy as a system, the current domestic LED lighting market is pursuing the trend of light effects, municipal engineering and semiconductor lighting pilot demonstration projects. The so-called "high-efficiency LED lamps" used in the invention often fail to achieve the effect of the intended use of energy saving and emission reduction, resulting in a large negative effect.
In view of the current lighting market, this paper describes the difference between LED light source and LED lighting performance. It reveals the reason why the wind of chasing light effects spreads LED lamps from LED light sources. It is emphasized that the luminaire performance of LED luminaire products should be coordinated with other performance requirements, and the luminaire performance should be based on the performance of LED luminaires.
