Can users continuously buy the same LEDs luminaires for a long period

LEDs for illumination seem to be rapidly growing in some developing countries, particularly in China for government backed national-wide street lighting projects. But traditional lighting giants still hesitate to jump into this huge market since some intrinsic issues exist in the LEDs industry for real illumination applications. The problems can be concluded “Does the useful life (L70) of high power LEDs lighting Luminaires can be really lasting for a long term (>50,000 hrs) as claimed? Do lighting companies can offer a sustainable LEDs Luminaire to fitting the applications from time to time?” Can users continuously buy the same LEDs luminaires for a long period?”

In NeoPac, we are completely solving the problem by offering NeoPac Universal Platform (NUP) and sustainable standard LEDs light sources to the industry. By adopting our fixed-maintained-lumen and form factor, 60,000 hrs useful life (L70) , system-in-package, point-like-source NeoPac Light Engines, the lighting brands will be able to make their own sustainable NUP-based luminaires easily to fit actual market needs” Jeffrey Chen said.

NeoPac Opto is going to launch its standard point-like-source NeoPac Light Engines at 500 lm, 700 lm, 1000 lm in White and 350 lm, 500 lm, 700 lm in Warm this year and adding 1400 lm in White and 1000 lm in Warm in 2010. Another 2000 lm in White and 1400 lm in Warm will be expected to launch in 2012. There will be totally 10 standard LEDs lamps with sustainable form factor (500 lm/700 lm/1000 lm/1400 lm/2000 lm in White and 350 lm/500 lm/700 lm/1000 lm/1400 lm in warm) for steadily offering to lighting industry in coming years.

If we can’t define the maintained lumen output and useful life (L70) of a lamp, we can’t call the lamp a real light bulb! This is really an intrinsic problem for current LEDs package and LEDs lighting technology platform. Even same LEDs package (lamp) adopted by different luminaire makers will result different lighting effects and different product useful life (L70). Since LEDs chips and phosphor are highly temperature-sensitive and high Tj will directly impact on optical and electrical performance of LEDs, as well as the overall quality and reliability of LEDs Luminaires. Different lighting fixture assembly process and different thermal management scheme result different LEDs junction temperature (Tj) and further result different overall lighting performance.
