ITRI Exhibits Circadian LED Lighting

 

Adjustable spectrum LED lighting features at 2018 Taiwan International Lighting Show (TILS) between April 25th and 28th

Taiwan's Industrial Technology Research Institute (ITRI) will display adjustable spectrum LED lighting that conforms to circadian rhythms at the 2018 Taiwan International Lighting Show (TILS) between April 25th and 28th. ITRI is assisting local lighting manufacturers in identifying untapped growth opportunities.

The 'LED Lighting and Health' pavilion spotlights adjustable spectrum LED using multi-chip multi-colour module design. Specific wavelengths can be mixed to form white light to provide the human circadian rhythm health effects. The adjustable spectrum LED lighting module developed by ITRI provides white light with the same colour temperature as seen by the eye, but the ratio of red, blue and green light is in fact different. This leads to different amounts of melatonin inhibited by light and consequently impacts one’s day and night perception unwittingly.

Chih-I Wu, ITRI's VP and general director of Electronic and Optoelectronic System Research Laboratories said that the increasing maturity of LED technology is gradually expanding the scope of applications in the LED lighting market. Contrasting with the past when LED lighting R&D centred on boosting efficiency, focus nowadays tends to be more on raising added value, he said. In practical terms, this marks a transition from "technology R&D centring on lighting alone" to "system integration and smart applications." Taking an office setting for example, efforts today are designed to make lighting comfortable and energy efficient, while at the same time ensuring worker efficiency and health.

Wu explained that ITRI hopes to combine its strengths in LED and ICT together with innovative ideas to help Taiwan's LED industry escape from cutthroat competition that is engulfing much of the sector and instead set its sights on untapped Blue Ocean opportunities.

ITRI also set up a 'Smart Light-Smart Life' pavilion that features smart LED power supply with failure detection and reporting functionality. ITRI has already transferred this technology to Great Connection System which in conjunction with other ICT has created a low cost, energy saving, and reliable LED lighting control system module that can detect failures. The development of this technology alleviates the need for additional sensors, as the system can instantly detect the status of the light fixture and report it directly to managers or the vendor, thereby ensuring real-time monitoring and reducing manpower and maintenance costs.

Robert Yie-Zu Hu, ITRI's VP and general director of Green Energy and Environment Research Laboratories, commented that ITRI has long been committed to developing smart and highly efficient lighting technologies, with a particular emphasis on quality in LED lighting. The smart LED lighting module that automatically reports failures provides greater convenience and speed in maintaining lamps. This will lead to greater customer satisfaction and boost product image, creating a win-win situation for managers and customers. Moreover, ITRI is working with partners on developing ultra-high power LED lighting technology that will boost the lighting efficiency of LED lamps. This technology has already been introduced at a stadium in Hsinchu County where the level of illumination has been more than doubled and has better uniformity.
