Street lighting is an important part of the city, the conventional high-pressure sodium lamp is often used, high pressure sodium 360 degree light, light loss caused major shortcomings huge waste of energy. Currently, the global environment is deteriorating, countries are developing clean energy. With the rapid growth of the national economy, China’s energy supply and demand have become increasingly prominent, there is a serious power supply began to shortages of energy is urgently needed to solve the problem. Therefore, the development of new high efficiency, long life, high CRI, environmentally friendly energy saving LED street lighting of the city has a very important significance.
LED street lights with conventional high-pressure sodium lamps is different, high power LED street light with low voltage DC power supply, the power-type GaN-based blue LED with yellow phosphor synthesized efficient white light diodes, high efficiency, safety, energy saving, environmental protection, long life fast response, high CRI unique advantages, can be widely used in urban road lighting. Housing available PC pipe production, high temperature of 135 degrees, low temperature of -45 degrees.
As the world’s most high-profile of the new generation of light, LED because of its high brightness, low heat, short-lived life, non-toxic, recyclable applications, etc., are known to be carried out in the 21st century’s most promising green lighting.
From 1962 the first red light only since the birth of the semiconductor light-emitting diodes, people continue to develop orange, yellow, green and other color LED, and for a variety of signal indication, logos, digital display, and gradually developed into a small LED display, etc. . It uses solid semiconductor chip as light-emitting materials, when the release of excess energy, causing the photon emission, can be applied to produce a semiconductor light source PN junction is made of the LED, came in the early 1960s, in 1964 successfully developed the first red light-emitting diode, yellow LED appears.
America is currently estimated that about 36 million lights, the end of last year, the United States LED lights penetration rate of about 6%, from around the United States government released tenders situation, this year’s estimated market size of the amplified standard case 40 to 45 % this year, before the end of the LED street light penetration is expected to grow to 10 percent, the company outlook with the market performance this year will also be expanded and stable growth of 40 to 45%, the future still has much room for growth.
Compared to Taiwan and mainland China, in fact, higher tariffs in Europe and America, and in the high tariff environment, both the Government and the people for saving products is relatively felt, especially in the United States every continent the high cost of public electricity costs, not Central Government to promote, local governments will actively carry out street lights replaced less multilayer barriers hinder government, the U.S. replacement market development speed street representing Taiwan and China will be more rapid.
In addition to the U.S. market, the industry is also optimistic about the development of the European lamp replacement market, especially in Europe, the government is limited by the current poor economic conditions, the real opportunities not replace fermentation, now is the layout and each industry to prepare in advance a good time, once the European economy improved, replacing the huge business opportunity ensued, Taiwan LED industry can replace the opportunity to compete for the lights of the battlefield, it is no longer only the Chinese mainland.
