Global LED Forecast: Green Development Trend of Lighting
Energy conservation and environmental protection are the paramount consideration for many countries. Under Paris Climate Agreement, the countries all over the world have the responsibility to decrease the carbon emission, and hence suppress the temperature raise by 1.5 to 2℃. US government promises the carbon dioxide emission will be reduced by 1/4 by 2025. What are the ways to achieve this?
It is observed that the traditional lighting equipment is a great source of energy consumption. For instance, the incandescent bulbs, metal halide and halogen flood lights consume so much energy on heating up process. In other words, majority of electrical energy converts to heat instead of light.
In additional to large power needed for the above conventional lighting, the life span of incandescent or metal halide lamps are extremely low. Therefore, we need the frequent disposal. As a matter of fact, more disposal means more manufacturer, which in turns further increasing the carbon dioxide emission during the manufacturing process and transportation. Now the question is, why not using the lighting that lasts longer?
New era of LED lighting: Green lighting solution
When it comes to environmentally friendly lighting solution, LED does a great help to reduce energy wastage and burden of landfill. LED lights have 20 to 40 times longer using time of metal halide lamps or incandescent lamps. In fact, the life span of LED lamps nowadays is about 80000 hours, which is equivalent to 25 years or more. Besides, due to its completely different mechanism (mainly use current to drive the lighting process), 95% of input energy goes to light if we use LED lights. You can compare the conversion rate of 5% of incandescent and 25% of metal halide.
According to US research, the following results can be achieved after switching to LED: reduces 258 million tons of carbon dioxide emission. By 2010, it is predicted that 55% of incandescent lamp will be replaced by LED flood lights.
Therefore, we are looking forward to seeing the use of LED, a green lighting solution.
