LED lighting industry hot: why Americans prefer incandescent?

Introduction: the U.S. government officially announced in January 1, 2014, in the United States a total ban on the production and import of incandescent lamps, and the existing products have been produced can continue to sell normal. Familiar with the principle of incandescent lamp knows the incandescent luminous efficiency of the bulb is very low, most of the electrical energy and has not been translated into practical use of energy, while about 90% of the electrical energy is directly converted into heat energy waste, and why Americans prefer incandescent lamps? (below: LED CEOs)

Question 1: what is the root cause of incandescent light in the United States?

Advocate: Wen Shang Sheng

Chen Wenji: first, Europe and North America where the weather is cold, like warm light and heat of the lamp, so the energy-saving lamps in Europe and the United States, the replacement rate is not high; second, the filament complex.

Xu Bo: Europe and the United States is a blue eye so like low color temperature, Asians like high color temperature.

Cao Chuanshuang: China largely promoting policies, government power has changed the habit of using the energy-saving lamps in the promotion, no government can not be so popular, Chinese supermarket is very realistic, dozens of pieces of money no one to buy, subsidies than incandescent lamp is also cheaper, most people like.

Chen Wenji: part of Europe and the United States self-confidence! They are based on the affirmation of the original civilization! Our people are still a little impetuous, the city is also evident in the construction of innovation. Europe is a combination of the original style to build a new house standard planning, China is the destruction of ancient buildings large demolition! Than the United States National Museum of cultural relics, but also a long history of the ancient buildings removed several times, deny the original civilization and innovation! Lack of confidence!

Xu Qinghui: color temperature is not the essence of energy-saving lamps, LED have warm colors. I'm afraid to look at the nature of culture, government guidance and other aspects. The United States Department of energy has always been a slow type of love, "cold water", both for energy-saving lamps or LED.

Li Jie: at the time of the introduction of energy-saving lamps, because of energy-saving lamps containing mercury, the United States worried about damage to the body, but not conducive to recycling. In the LED just launched, because of technical reasons, leading to energy saving.

He Mingdao: there are a lot of irreversible pollution in the process of production and recycling of energy-saving lamps, the energy is saved on the surface, but the cost and harm of pollution treatment has been greatly improved. Including the LED, is also the same problem, aluminum parts after the heat treatment process, oxidation electrophoresis, etc., the same is irreversible pollution.

Topic two: replace the traditional Chinese lamp LED lamp technology

Advocate: Wen Shang Sheng

Cao Lihui: most of the Chinese lamp is yellow, and the glass cover is not very good. Not only to consider the appearance, but also take into account the lighting function.

Cao Chuanshuang: This is indeed necessary to change the LED, the directional control of light, directional LED hidden in the shade.

Xu Bo: Chinese light from the light point of view is not much use, but the effect of the whole lamp luminous uniformity is good, we are actually close to 60%.

Ding Deliang: can spray fluorescent powder in the lamp housing, and then to go to get the blue lamp excitation, different color temperature requirements, the LED in the upper pole is connected to the bottom of the heat, get the lamp appearance.

Yang Wenhui: too far away from the lamp phosphor distance, light efficiency is too low, the budget together with incandescent like.

Ding Deliang: the distance will be sent to the center of the bubble with a candle lamp lens to achieve uniform.
