Green Energy Trends for 2010: the Compound Annual Growth Rate of LED Light Source Reaches 32% with the Advancement of LED Lighting Technology
Energy-saving is one of the key focuses of current social concerns. There are significant differences between various energy-saving technologies – while any technology that reduces power consumption saves electricity fees, and reduces environmental pollution by lowering carbon dioxide emission levels, some technologies consume so much energy to an extent that it offsets the amount of energy saved. Nonetheless, these technologies help lower pollution levels.
Green Economy is Expected to Stimulate Demand for Energy-saving Lighting for Three Years
Is the public concerned about greener buildings? The solar panel system and its high-efficiency power conversion equipment are extremely expensive, and the building materials with heat insulation or a heat exchange system are not common. The more easily accessible products related to green buildings are Led lighting and CFL lighting. Regulations to phase out incandescent bulbs and preferential taxes polices for companies that encourage the use of these energy-saving lights stimulate demand for energy-saving lighting.
led lighting and CFL Lighting with Their Own Respective Strengths
Energy-saving technology in CFL lighting is already quite mature, and its price is already at an affordable level to the general public. Apart from the implementation of regulations to phase out incandescent bulbs by governments around the world, electric power companies in the US market also provide users with CFL bulbs, either free of charge or at an extremely low price. These moves significantly boost the shipment of CFL lamps. China produced a total of 62 million CFLs in 2008, and 120 million in 2009 (including bulbs and tubes) which accounts for about 80% of CFLs used worldwide.
As for
Led lighting, it was only emerging before 2008. In 2009, the number of LED lighting related products rose significantly. In addition to public area lighting and commercial space lighting, general lighting for household use are also introduced in the market.
The lifetime of CFLs is long, but LED lighting products claim to offer longer lifetime, but their costs are higher, too. Major LED lighting products on the market include MR16 series lights, freezer lights, strip lights, track lights, cabinet lights, landscape lamps and arc lamps (can be used for direct and indirect lighting), and nightlights. On the other hand, CFLs are mostly seen in residential buildings, such as replaceable bulbs (eg. E27), ceiling luminaire, downlights, and surface mounted lights. The T5 tubes are also widely used for the direct lighting of convenient stores, offices and other indoor spaces.
Although CFL offers high luminous efficacy at a low cost, its mercury content is problematic - if the bulb is broken, the mercury vapor leak is harmful to both the health and the environment; furthermore, it cannot simply be thrown into the trash bin as the groundwater will be contaminated even after waste processing. In this case, LED lighting is more suitable as the light source for general lighting in the future. Developed countries such as EU members are conducting researches on the development of regulations of phasing out CFLs, which will also help boost LED market.
