Chinese Residents LED "Knowing More With Less," What About Korea? Japan Do?

- Dec 07, 2015-

He entered the last month of the year, indicating that 2015 coming to an end. According to the National Development and Reform Commission announced in 2011, "China to phase out incandescent Roadmap (draft)", from October 1 next year began, will prohibit the sale and import of 15 watts and above ordinary incandescent lighting. This means that China gradually phase out incandescent light route through the mid-term review of the fourth stage into the fifth stage, with 130 years of history of the incandescent lamp will really want to slowly fade from view. It is predicted that with incandescent declining, will boost the LED lighting market in 2016 increased to $ 30.5 billion.

Obviously, in vigorously promote energy conservation, and actively respond to climate change has become a global trend of development trend, most countries have been introduced out of incandescent policies to accelerate the phase-out of inefficient lighting products. US unrivaled professional market research company IHS architecture had said it expected to 2022, global residential lighting applications in nearly half of the bulb will be LED (42%), while the proportion in 2014 was only the last 4 percent. Earlier, at the Institute of Photonics, Japan residential lighting Research, a South Korean indoor lighting research will be conducted by Lingnan University, Dalian University of industrial electronics, Japan, Korea residential lighting joint survey in 2011 on the Year - 2015 contains the above three countries conducted a joint survey of residential lighting summary, comparison and analysis, they expect that this will jointly develop the future for the Asian characteristics of residential lighting standards and to build a green residential light environment to provide a reference and basis.


Three LED light source used in a proportion less than one percent

The joint survey results show the status of residential lighting, the type of light source in use, Chinese, Japanese, Korean family living room lighting States still have a considerable part of the population in the use of incandescent lamps, which China's utilization rate was 13.1% Japan 32.9%, South Korea 39.0%; proportion of fluorescent tubes, China 31.4%, Japan 37.7%, South Korea 21.6%; the proportion of energy-saving lamps use, China 53.1%, Japan 22.5%, South Korea 31.5 %; Currently, the proportion of LED's at least, China is only 3.6%, Japan 6.9%, South Korea 7.9%.

Which you can glimpse, in the case of an incandescent lamp gradually withdraw from the stage of history, fluorescent tubes and CFLs usage remains persistently high, China is accounted for by energy-saving lamps to the "half." From another perspective, this also confirms the three countries were higher than one percent of usage LED lighting applications market, the future still has great room for growth.


Japanese residential lighting energy consumption is relatively highest

At the same time, the survey found, in power distribution, power consumption of residential living room less than 100 watts of power, China accounted for 95.28 percent, South Korea 95.54%, the result is quite close. Japan was only 41.43%, indicating that the Japanese respondents living more than 50% greater than 100 watts of lighting power, relatively speaking, high lighting power consumption in the country. In addition, China, Japan and South Korea the average living room lighting power were 49.7%, 155.7%, 57.1%, the same percentage of the three groups in China to a minimum. These data objectively reflect the energy levels of countries surveyed.

In addition, the survey also were in the living room illuminance measurement, namely the so-called illumination light intensity, that the surface of the resulting flux and the illuminated area ratio, for the strength and body surface area is the amount of light illuminated indicating the extent of the unit is lux (Lux or Lx). The space is measured according to the average of the lights 30 minutes after the five data collection points, where China is 63.4lx, Japan 135lx, Korea 209.7lx. China, Japan and China in the living room complete reading, watching TV, chatting trend presented substantially the same general illumination, the average of the three acts of lighting, China Housing respectively 53lx, 83lx, 71lx; Japan respectively 161lx , 164lx, 160lx.


Chinese residents LED light source "Chita with less"

It is understood that, in recent years the world of healthy lighting, energy saving are sparing no effort to advocate and promote, support policies for LED lighting have also been introduced. Among the Chinese mainland, in November 2011, the National Development and Reform Commission and other departments jointly announced the five years to completely phase out incandescent roadmap. China Taiwan also planned incandescent FMCT policy started in 2010, and until 2012, power consumption will be more traditional incandescent halted disabled. The Japanese government also intends in 2020 to ban the production and import of energy larger incandescent and fluorescent lamps, and early in 2008 it made under the provisions required in 2012 a total ban on the use of incandescent lamps, vigorously promote LED bulbs. While South Korea had also announced before the end of 2013 prohibiting the use of incandescent lamps.

Survey shows that after years of promotion of education, imperceptibly, China, Japan and South Korea more than 70 percent of the residents of the LED are all a better understanding of the extent of Chinese residents LED level of understanding as much as 86.2%. Among them, the Chinese people on low power consumption LED light source cognitive more, while the Japanese long life, low power consumption advantages of a more familiar, the Korean people are more familiar with the characteristics of environmental protection. However, although the Chinese people to understand the highest level for the LED, but the LED light source of usage in the three countries is the lowest, reflecting the LED light source in China is vigorously promote the same time, the sales price is still relatively not enough "people."


Three residential lighting needs improvement "common ground"

According to the survey, demand improvement in residential lighting, the Chinese, Japanese, 韩居民 brightness level and brightness whether adjustable high demand in these two areas, which indicates that the residential environment brightness light unsuitability. Therefore, the investigation team recommends, in the light environment to create the atmosphere, creating the effect of the same time, we want to make the brightness of rigorous calculation and measurement in order to avoid human discomfort. In addition, consider installing a light source with a controller, appropriately adjust the brightness level through intelligent control, so artificial light and natural light synergistic effect to maintain luminance balance. In addition, residents of the three countries in the light of the residential environment, energy levels have considered, to achieve visible green light, low-carbon lighting has become a consensus.

At the same time, because the status quo of their own national lighting differences, improve lighting also exhibit different bias. Where family in China's emphasis on whether easy cleaning; Japan's household is more focused on the type of light source; Korean families are more concerned with ease of operation. By improving lighting needs survey, a direct reflection of the status quo deficiencies lighting, the production process also indicates the next step should be the light source, intelligent control mode and user-friendly design and other aspects to improve and enhance the quality of residential light environment.


Japan and South Korea the United States and the four countries significantly different residential lighting standards

Investigation by the Japanese team statistics, Han measured illuminance data to compare residential lighting standards, found large differences between countries in the average illuminance, which South Korea reached the highest 214lx (full light) and 148lx (need lights on) Japan is 135.6lx (average), followed by the United States, reaching 73.2lx (average), China to 69.9lx (average) runner bottom, far below the average level of illumination, Japan and Korea.


About residential lighting standards, following the United States to join together to compare the situation (see table), we can see four countries exhibited differences can be quite significant. Under Schedule display, Japan, South Korea, the United States and three standard lists are more detailed, Japan and South Korea conduct illumination in a domestic environment, according to a detailed breakdown of life scenes. US residential lighting standards, even illumination of different ages and behavior were distinguished. In contrast, the Chinese division of activity classification is relatively "primitive" is much more to "read" a classification, for example, China's standard is 300lx, while the United States will be developed in detail according to the division out of the three age groups the reference values - values are as follows: 25 years of age 100lx, 25 ~ 65 years of age and older 200,65 400lx.
