The development and trend of high efficiency LED lighting applications

The global LED lighting market in the market after the mature period, some field showing the finishing state, according to dramexchange LED Consulting Research Center (LEDinside) data, in 2016 the global LED lighting market reached $29 billion 600 million, 2017 is expected to grow to $33 billion 100 million, LED lighting penetration rate is 52%, the future is still quite can play the space, but the price and market competition of low order, not the international manufacturers would like to see some more powerful products and technical barriers to the first-line manufacturers, efficient LED lighting and niche market.

And benefited from regional lighting market development, in 2016, European LED lighting accounted for 23%, followed by North America and China market, the overall growth rate of the Asia Pacific lighting market as fast. LEDinside visits lighting manufacturers and major LED vendors to explore new markets on efficient LED lighting routes.

U.S. lighting market to attract large manufacturers to push high efficiency LED tube

The economic policies of the US market affect the development of the lighting industry in North America, and the local assembly of LED lighting fixtures being promoted by the United States will meet the needs of local market segments and expand the scale of the local market.

LEDinside believes that this will produce similar effects of previous U.S. local solar installation service industry rise, driven by more Native American LED lighting project team was born, processing new projects and to replace the traditional lamp, LED lamp and other primary business, adding more American jobs.

Major U.S. manufacturers are actively developing LED lighting business, LED lighting products accounted for the rising, LED commercial lighting / engineering lighting demand is strong in the United States market. Among them, the Troffer, flat light, tunnel lights, patio lights market demand growth is the most rapid, and accelerated to the development of intelligent and optical communications and other fields.

LEDinside said, in 2017 the global LED commercial lighting (including lamps, Toffer and panel lights), the output value of 6 billion 347 million U. s.dollars, 2016~2020 composite annual growth rate of 12%. LED lamp needs the North American market is very high, in the DLC 4 specification came out, many manufacturers and the standard case contracting unit to pay more attention to comply with DLC 4 specifications of products, the LED lamp design and cost structure, the choice of manufacturers LED chips will produce what kind of impact?

Philosophy of trade-off between high current density and low current use of LED components

At this stage, because of the market and application of different lighting manufacturers must be careful in choosing LED chips and LED components. At present, the mainstream of the new application of the market is divided into "high current density" and "low current use" of the two LED chip design and selection philosophy.

International LED epitaxial Dachang crystal electric marketing center director Lin Ziyuan pointed out that the demand for high efficiency LED, LED chip in the price has been reduced to the sweet spot, for lighting manufacturers, choose LED chip with less teeth, let them work with the current density higher, with Over Drive to realize the cost of lighting this is generally reduced, LED lamp or LED bulbs, LM per dollar to pursue, but also the proper collocation cooling module, a heat dissipation material cost is equal, although is the mainstream market, but the quality of light, the life of the product, in fact, have many challenges. For example, a LED designed with a high current density is too small to be packaged in a LED tube, which can present a negative effect on the illumination quality and heat dissipation of the LED tube.

Another successful way is "low current use", that is, in the high quality and efficient LED tube, use more LED, avoid these negative problems. The philosophy of low current usage is to drive LED chips with a lower current than the established specifications, and put enough LED packages in a tube to look better. With the formation of the glass tube trend, gradually replace the plastic tube half cover under the condition of low current efficiency using multiple LED chip, not only the lighting effect is improved, the service life of product, quality and stability is better, but also with the United States DLC 4 high efficiency, realize the whole lamp above 150lm/w high efficiency.

In the light of the whole group of LED lamp efficiency requirements improve, design the appropriate LED chip, plus heat, Blaster, glass tube structure, high efficiency and high quality product price will be higher, in line with market expectations.

High efficiency LED lamp components need to carefully choose the patent suppliers

Crystal current customers in the United States, has been successful in hospitals, public buildings, buildings and other fields cut into the market, and actively replace the T8, T5 traditional fluorescent tube to LED tube. At the same time, American manufacturers have become a trend in the United States, and the acceptance of the owners and the market is even higher than before. A high efficiency LED lamp needs less LED chips. It is several times as many as ten times as many as LED bulbs in general.

Crystal electric R & D in the LED chip not only has many years of experience, there are quite a few of its own patents and patent LED cooperation, the products are exported to Europe and North America market customers, would be more willing to choose the solution crystal, crystal electric can be a large and stable amount of supply is the main advantage. In addition to the North American market, crystal electric also cut into the quality of considerable attention to the Japanese market, the recent 2020 Olympic Games in Tokyo, there are many generations of LED lighting demand.

On the whole, some markets need to be able to operate with low current, but also be able to achieve high efficiency LED products, low current and high quality
