Industrial 4.0 era, LED industrial lighting development how?

May 15, 2017

There is no worker in the workshop of the automated factory, and the machine is running automatically ... it looks like it is no longer just a dream. As early as 2015 the Chinese government announced the "China made 2025" Chinese version of "Industrial 4.0", the entire system by the intelligent products, intelligent production, intelligent plant three major components. In the realization of intelligent factories, lighting is an indispensable part. So, we can not help but ask, how is today's industrial lighting development? Will it change in response to changes in the times?


LED industrial lighting, small public market, the great charm

In fact, compared to home, commercial lighting, industrial lighting seems to be only a relatively small family of lighting and low-key members; compared to plant factories, automotive lighting, infrared UV LED, optical communications and other media reports in the high-frequency vocabulary , Industrial lighting is relatively popular words, but it also does not affect its charm - in the LED replacement demand continues to heat up and government-related subsidies to support the industrial lighting market growth rate.

According to the relevant market research institutions survey results show that 2016 global LED industrial lighting market size of 2.292 billion US dollars, and will grow at an annual rate of more than 16%, is expected to reach 39.35 billion US dollars in 2018, the market size in 2020 will reach 5.204 billion US dollars The And China's industrial electricity consumption has accounted for more than 70% of the total electricity consumption, industrial demand for energy-saving strong, huge market space also makes China's LED industrial lighting penetration is expected to further speed. According to forecasts, in 2015, LED products accounted for only 6% of the entire industrial lighting products, it is estimated that in 2035, LED market penetration will reach 86%.

At present, LED industrial lighting users mainly for foreign-funded enterprises, state-owned enterprises and some outstanding private enterprises. Among them, foreign-funded enterprises have advanced management and environmental protection concepts, to accept the LED earlier, the LED lighting products related knowledge and technical parameters are more clear, is the beginning of the use of enterprises; and state-owned enterprises in order to the corresponding national energy-saving emission reduction policies, Also began to use LED replacement light source; some excellent private enterprises in order to control production costs and improve the overall competitiveness of enterprises, but also gradually accept the LED industrial lighting.

Product performance has gradually approached metal halide lamp?

Although the market development prospects are good, but the field of industrial lighting is still considered the last one to be LED lighting applications. At present, the application of LED in industrial lighting is mainly for small and medium power lighting, and in the field of high power lighting applications, metal halide lamp relative to high power LED light source cost is relatively high, LED lighting is also unable to overwhelm advantage to replace.

However, it is gratifying that in March 2017, the US Department of Energy CALiPER (commercial feasibility of LED product evaluation) project team based on LED lighting products energy efficiency labeling program project group (LED lighting fact) database data, published LED industrial lighting Product presentations show:

1, LED industrial lighting products luminous efficiency is generally higher than the existing products, LED lightinging statistics in the statistics of LED lighting products, 23% of the luminous efficiency of more than 130lm / W. 5% higher than 150lm / W, 1% higher than 175lm / W. These are more than fluorescent lamps and metal halide lamps average luminous power, their luminous power is only 70 ~ 90lm / w.


2, in general, LED industrial lighting products and similar products compared to a certain advantage. Statistics of the product, 50% of the luminous flux between 11000 to 22000lm, in addition to more than 150 products of the luminous flux of more than 50000lm, so the average luminous flux of 18000lm. The power of these LED products is equivalent to 1000w metal halide lamp.


3, in the color temperature and power, LED product performance and the traditional metal halide lamp and fluorescent lamp is no different. 65% of the statistical products, color rendering index in 80s, the vast majority are industrial products. Half of the statistical products have a color temperature of 5000K or higher, higher than traditional industrial lighting fixtures. These high color temperature products and other types of products compared to a higher luminous power.

Of course, this is only the United States industrial lighting product data, as the domestic LED industrial lighting product technology development level how? There is no relevant report, but perhaps we can in June this year, the global attention of the Guangzhou International Lighting Fair to find the answer.

Product trends will gradually modular, intelligent?


After all, industrial lighting products, because of its relatively simple demand, and more to meet the lighting, uniform effect, so this product is relatively less innovative. However, recently, industrial products in the function and application of a breakthrough, the use of installation module (with) + lighting module design, lighting module, a narrow light, medium light, wide light and two-way polarized light design, and can carry human induction , DALI, daylight sensor adjustment and other functions.


Again, there are industry analysts pointed out that intelligent lighting will become the field of lighting practitioners into the field of industrial lighting "ETC". Because the energy-saving effect of intelligent LED lighting system allows industrial lighting under long-term use, more cost-effective than home lighting recycling competitiveness, more incentives to promote the owners to replace the original lighting products.


Littelfuse senior technical marketing engineer travel Gong has made different views. He believes that at this stage, the existing plant to import LED intelligent lighting, compared with no real benefits, for the existing plant lighting, only the need for on-site staff control, do not need to import intelligent control. But if the new plant, import industry 4.0 concept has a real meaning.


Profits are relatively stable, but difficult to cut

As industrial lighting mostly stealth access to the channel, you can avoid the price war and the specifications of the war, the profits are relatively stable, which also attracted a public LED manufacturers to actively cut into the industrial lighting market.


At present, the leading manufacturers of industrial lighting, including the United States GE lighting, CREE, CooperLighting; Japan Iwasaki Electric, Toshiba and China Ocean King in recent years have a good performance. In February of this year, OSRAM announced the acquisition of lighting service provider Maneri-Agraz, mainly for commercial and industrial facilities to provide energy-efficient lighting solutions; March Keming Lighting held in Changzhou business conference to announce the return to industrial lighting positioning; GE has recently been released is considering the sale of consumer lighting business, the focus of the transformation is mainly digital industry, the layout of industrial networking, 3D printing and other fields, but this is not the case of the United States and the United States, Excluding GE's next effort to promote industrial lighting intelligence.


"But the biggest problem is that it takes a long time to work and explore, because the characteristics of industrial lighting is a small amount of diversity, so it will be more difficult, the order will be more difficult to obtain." Littelfuse senior technical marketing engineer tour Gong Hao admitted, Just in the plant in the LED lighting, the application of different environments, such as high vibration, dust, explosion, and even clean rooms, etc., for LED lighting requirements will be different, coupled with LED lighting should also consider Engineering problems, so in general, need to consider for a considerable amount of the characteristics of the market point of view, a small variety can be said that the main features of LED industrial lighting, so from the system integration and even the whole plant output point of view, the product itself The quality must be enough to make the integration industry trust, or can not enter the lighting system within the plant.
