Forecast: 2013 LED replacement light source overall demand for 1 billion 500 million

NPD DisplaySearch recently released a special report on the LED lighting market. The report pointed out that, after years of technology accumulation and improvement of development, LED lighting has now begun to gradually replace the traditional lighting bulbs.

This year, the lighting market continues to grow rapidly, mainly divided into commercial office lighting and government subsidies streetlights related markets. Business growth momentum mainly comes from the lighting bulb and lamp, as part of commercial lighting applications open for 24 hours, for example: the basement and lane lights, so energy saving is still the most important power to replace the LED light source.

Because the world is still a controversial issue for the development of nuclear power generation, electricity prices trend is likely to continue, so BPD forecast in 2013 LED to replace the overall demand of the light source is 1 billion 500 million, which spotlights the highest rate of penetration is 17.8%, bulb permeability in 10.1%, lamp tube penetration of 5.8%, street lamp penetration rate of 10.5%.

From the regional perspective, the main demand for the replacement of LED street lamps is from mainland China and emerging markets such as Brazil, Russia and Mexico. As for the consumer market acceptance is still the highest in Japan, the main reason is that the Japanese area or power saving tubes is a long tube itself price is high, but in recent years, Japan's major consumer brands such as Panasonic, Toshiba, Mitsubishi, NEC and Sharp are competing to push out all kinds of LED lamps and replace the LED bulb.

We can see that the traditional incandescent lamp because the luminous efficiency has been stable and will not be further progress, so only in the brightness of the LED specifications and price of the traditional incandescent bulbs and close to the popularity of. In the design, LED lights still follow the traditional bulb appearance, and the luminous efficiency of continuous improvement of the situation, the future size of the LED light source than the traditional light source is smaller, lighting design uses light limit will be less, can bring more changes of light source. At present, some manufacturers have already put forward the concept of disposable light source, the light bulb design main from the past light (LED light source), machine (lighting mechanism design), electricity (power supply design), heat (bulb overall cooling) into account, to focus on protecting the most easily damaged parts because of thermal power, and the price will be cheaper and can be mass-produced LED light source instead of disposable structure; because the heat considered reduced, so in the heat dissipation material can lower the price, and because of not considering LED light source life, so the chip can be used to drive high current, when the source brightness LED light attenuation, power supply can still use, only need to replace the LED light source can be restored to the original brightness. This concept is a new concept, subversion of the LED must be long life idea.

NPD DisplaySearch LED lighting market report also describes the LED bulb design direction:

The factory or a large number of bulbs produced by the bubble, without novelty, to take into account the production of automated production, with a large number of single target production.

In addition to the original design of its own brand of light bulb design, the price is still an important part, because a lot of LED bulbs or outside the lamp cover.

The three-dimensional illumination angle, which is extended from 2D's surface light source to 3D, is converted from a directional light source to a light bulb (320 degree light), which is close to the traditional tungsten filament lamp and the power saving bulb. In 2013 the trend will be to improve the form of LED light source, columnar or line shaped light source will gradually become the mainstream.

According to NPD DisplaySearch analysis, 2013 LED lighting market penetration will reach 10.6% by the end of the year, and is expected to grow to $26.4% in 2016, indicating that the LED lighting market will have a sustained and healthy growth.
