The Origin of "A Global Green Lighting Mission..."
Today, in the 21st century, we are facing energy crisis and environment protection issues which are severely impacting human’s sustainable development. At first glance, it seems hard to be complete in both respects on reducing the emission of greenhouse gases and sustaining human’s development. In fact, mitigating global climate change and seeking sustainable development are both achievable goals that require mankind’s joint efforts together.
Developing nations should support and target to reduce substantial greenhouse gas emission growth while developed nations should take more responsibility in dealing with climate change. All political and economical powers should comply with any kind of promises that leads to a better global environmental outcome to save the beautiful planet we live.
Simply by adopting energy conservation LEDs lighting, near 1,000 Mt carbon dioxide emissions can be reduced, per year.
According to the statistics in 2005, lighting accounted for about 19% of total electricity consumption and 8.9% of total crude oil consumption. Whole together produced 1,900 Mt carbon dioxide emissions per year. By adopting LEDs luminaires built with light source having a maintained lumen efficacy of 100lm/W worldwide, carbon emissions amazingly can be pushed down to 900Mt per year which in real life means, gradually close those thermal plants that emits ultra-high carbon emissions (approx. 25Mt/yr) up to as many as 50. LEDs green lighting provides both non-governmental sector and governmental organization with a quick and effective emission conservation solution being measurable, reportable and verifiable.
Finance and investment: Global green lighting fund as a strong driving force
A global green lighting fund is the crucial driving force to get success in massive adaption of energy conservation LEDs lighting technology, no matter the developed nations or developing nations to achieve the committed goal of carbon footprint reduction. Government organizations making Energy Management Contract (EMC) as a mandatory legislation should develop financing solutions to facilitate investments in low carbon emission technology projects. The reward from the financing to the establishment of eco-friendly systems shall nourish the green light fund itself.
No matter which solution is introduced (EMC/Project Financing/Leasing), it is promoted in terms of meeting the interest of all aspects. Financiers have to obtain reasonable rewards in order to sustain and grow green lighting fund in strength. End users must be encouraged by benefiting from enormous energy-saving and emission reduction results and low-cost operation. Suppliers shall acquire sensible profits for improving LEDs illumination technology and maturing green lighting industry by lower manufacturing cost resulted from mass production. In this point of view, product reliability and sustainability of the subject-matter (LEDs luminaires) is the key factor to achieve the goal.
Boost the booming of green lighting by simple technical transfer model.
LEDs lighting is recognized as a high price and high technology integrated industry. Developing countries requires technical transfer as assistant in order to carry their green lighting mission out. SKD (Semi-Knocked Down) technical transfer solution for sure is the most effective way by transferring manufacturing skills, equipments, utilities, core components and experience together as a Turn-Key solution, which helps developing countries quickly develop their own base of operation and supply chain for LEDs lighting. In this way, not only cost of the LEDs luminaire will be reduced but also helps in mitigating carbon footprints in those countries as well as increasing employment opportunities & improving living standards. To developed countries, reasonable profit and carbon credit is rewarded due to green-tech exportation and technology transfer.
The adoption of sustainable LEDs luminaires is the key factor of completing the Global Green Lighting Mission.
For green lighting to satisfy those requirements from both human’s demand for long term development and environment protection, the sustainability of lighting product is of crucial importance. To LEDs illumination, being sustainable basically contains 2 implications:
- Can commercialized LEDs lighting products continuously offer consistent lighting effect without obvious lumen decay and color shift during a long useful life? For a person who owns general knowledge of LEDs lighting technology should be aware of the importance of the relationship between the junction temperature (Tj), reliability and the useful life of the LEDs.
- The 2nd concept could arise from a question by an end user, “Is it possible to buy a same lamp which has consistent scheme in effect to sustain for installation over years together without worrying any perceived differences?”The sustainability of LEDs lamps in this sense should imply the consistency in appearances (dimensions, sizes, and number of emitters, etc.,) of the lamp, and further the photometric characteristics (brightness, light distribution, CCT, and CRI – Color Rendering Index, etc.,) The lamp developers and manufacturers would be happy to see the benefit by providing sustainable solutions to help boosting the market while reducing the cost with fewer dead inventories to build within the whole supply chain.
A sustainable LEDs lighting product featuring with ultra-long useful life (L70 > 60,000 hrs), undetectable color-shift and less than 30% lumen decay together could continuously decrease over 10 year’s emission produced by operating and maintaining the lighting system. The consistency of product characters satisfies the need of human’s sustainable development, which means LEDs lighting products with lower and lower cost and power consumption can be manufactured and supplied to market without changing, re-verifying lamps design despite the fact that LEDs lumen efficacy is to be increasing year by year. This is going to greatly promote the popularity of energy conservation green lighting.
To completely solve the mentioned sustainability problems (which could be devastatingly crucial from macroscopic view, indeed) for the LEDs lighting industry, it is necessary to develop a standard LEDs light source and a universal technology platform as an infrastructure that satisfies the needs of developing sustainable LEDs lighting. Such a technology platform should provide specifications that cover design rules for LEDs chip, packaging, assembly formulations, and proper ways to measure key parameters. To catch both concepts, a technology platform has been established by a system approach. The features include Multi-Chip-Module, System-In-Packaging, Point-Like Light Source, and thermal modules that are integrated altogether. The Standard Light Engine derived from the sustainable universal platform thus has been well developed like heritage being introduced to meet the flocking demand in the market.
Together with standard LEDs light engines, NeoPac Universal Platform (abbr. NUP), developed and promoted by NeoPac Optoelectronics, Inc., can help point out an accurate direction to the roadmap of technology development for the LEDs manufacturers. Based on this technology platform, LEDs chip manufacturers can produce LEDs chips not only to have the highly sustainable development in the technology but also could meet the market requirements. By adapting to this kind of highly sustainable technology, light fixture manufacturers could develop their own fixtures that fit the actual market needs keeping the same lighting effect for a long period in a shorter period. All the LEDs lamps developed based on this technological platform are naturally qualified to be mass produced as well as continually supplied to the booming market to come.
