Release date: 2017-07-24 Source: Semiconductor lighting network share: 
With the constant changes of the times, the LED lighting industry technology is also advancing by leaps and bounds. When it comes to the popularization of LED lighting, the light effect is no longer constrained, the price/performance ratio has been raised to the extreme, and the penetration rate has risen to the highest level in history. With the improvement of residents' consumption level, the improvement of light quality has become the biggest topic in the lighting market.
As we all know, modern consumers have a higher pursuit of LED light source, not only in the pursuit of simple light, but through the choice of light to create an ideal atmosphere of their own, such as in different lighting In the application scene, the designer makes the corresponding lighting design by selecting the color temperature, the index, and the color point of the light, and finally makes the LED lighting product create a warm and comfortable happy light environment.
Liu Xiuren, general manager of Development Crystal, who receives daily LED interviews, said that continuous innovation to create high-quality LED light source is the goal of developing crystal, and high-quality light source must start from the source, develop epitaxial wafers with high luminous efficiency, and add epitaxial wafers And packaging technology to effectively implement the vertical integration of LED.
Chip + package LED vertical integration
It is reported that the development of crystal positioning in the provider of LED integrated solutions, began to invest in this field in 2012, has now built dozens of domestic leading LED epitaxial chip production line and LED packaging production line. With the support of China Electronics and Jingyuan Optoelectronics, the MOCVD scale exceeds 100 units, and it can supply 500,000 pieces of 2-inch epitaxial wafers per month. It is China's leading epitaxial wafer manufacturer. Through the wholly-owned acquisition of Bridgelux, the company's leading LED chip and packaging technology, rapid development and manufacture of LED packaging, and the establishment of multi-level sales channels with the US Bridgelux and China Electronics' SINOTRON brand.
The development of crystal is different from other domestic chip manufacturers through the form of chip + package. Its business scope covers all industrial chain links such as LED epitaxial wafer, chip, package module, lighting application (material + chip + epitaxial wafer + package + technology + Patent), with the advantage of rapid response and low overall supply chain cost.
Bridgelux launches products with global patent protection advantages
It is reported that Development Crystal completed the acquisition of Bridgelux in the United States in 2016, and then quickly upgraded the luminous efficacy of Bridgelux's COB products, and launched the seventh generation COB products, and at the same time launched the global brand global patent in the industry. The full range of protected SMD2835 products, including 0.2W-3V, 0.5W-3V and 1W-9V, are cost-effective products. 　
Not only that, but the newly launched SMD5050 market leading light effect products at the beginning of this year are applied to outdoor street lamps, floodlights, and industrial high ceiling lamps. The Bridgelux SMD5050 Gen2 product addresses the challenging DLC4.2 requirements for light efficiency and longevity requirements. Now, Bridgelux has been launched to meet DLC4.2, indoor lighting applications SMD2835 0.2W 3V Gen2 products, this product 4000K CRI80 light efficiency reached 185lm / W or more, once listed, it is popular with customers. Export to the US for customers, to meet the DLC4.2 to provide assistance.
Some commercial shop lighting markets based on COB, through the cooperation with the American Lighting Research Center, Class A, defined by behavioral science methods, is people-oriented, high color gamut index (GAI), high color rendering index (CRI), high quality. The light-colored LED light source plays a decisive role in the finishing of the store lighting.
In addition, some special color point products create and render different atmospheres and environments for different application scenarios. Showcase 3000K uses LED light source technology to create the lighting atmosphere of traditional ceramic metal halide. StreetLandmark lets you find memories of high-pressure sodium lamp street lamps. At night, it is no longer a cold feeling (all basic LED street lights use high color temperature LEDs, giving a high-cold vision), and this product is also very suitable for the floodlighting of the building facade, creating A very grand visual effect. Especially some ancient Chinese buildings. Bridgelux also has a range of special color points for different scenes, such as Culinary (Meat Deli) for red meat or lobster lighting, and Specialty, which is already very suitable for lighting ceramic products.
The packaging market continues to be larger, Evergrande
Nowadays, the LED industry is rapidly shifting to the domestic market very quickly. The LED chip white light has accelerated the transfer to China. The market share of Chinese LED chip manufacturers has also exceeded 70%; the global packaging capacity is also accelerating. China's transfer, mainland packaging capacity will continue to maintain a certain rate of growth. According to the latest data from relevant data, the scale of China's LED packaging market in 2016 has increased from 64.4 billion yuan in 2015 to 73.7 billion yuan, an increase of about 14%. From the midstream perspective, domestic packaging companies have occupied a dominant position in the Chinese market. In the past two years, some of the international LED manufacturers have gradually withdrawn from the Chinese lighting market, which also brings more development space for domestic enterprises, as well as the development opportunities for the development of crystal. Liu Xiuren said that the overall development trend of the packaging industry is energy efficiency, color rendering, dimming and smart lighting, and market segmentation.
Liu Xiuren admits that if enterprises want to become bigger and stronger and become the leader of the industry, in addition to the pursuit of the quality of products, production capacity is also a very important part. Therefore, the integration process of enterprises into the industrial supply chain is very inevitable.
The quality of light becomes the pain point of the next segment of the lighting market
Any product can only be changed based on consumer preferences and market demand, as well as the process of adjusting the forward-looking insights of the manufacturing company. There is no doubt that the change from light efficiency to light quality is the LED industry. An upgrade, the impact on the industry is clearly positive and positive. Liu Xiuren mentioned this.
In recent years, consumers have been paying more and more attention to whether light quality is improved, mainly based on the following five aspects:
First, the information is developed, the understanding and application of lighting has accelerated the integration with the international, and the advanced lighting requirements have been passed down.
Second, the team of domestic lighting designers has grown stronger, and the designer's requirements for light have changed the lighting requirements and functional changes of lighting companies.
Third, the homogenization is serious, and the vicious competition of transition makes some responsible enterprises bravely shoulder the responsibility for product quality and social responsibility for lighting quality and quality of light products.
4. Over the years, a large number of common functional space lighting standards have been accumulated in China. Not only are lighting designers paying attention, but interior designers, architects, planners, owners and consumers are paying attention to the rationality and standard requirements of lighting. .
Fifth, the improvement of people's living standards, the further personalization and subdivision of the lighting space function, the designer's suggestion, the promotion of the lighting enterprises, the owners have more objective visual, psychological, physiological and other light quality requirements.
Liu Xiuren stressed that in the future, we will see more and more enterprises, not just producing lighting products, or just focusing on individual parameters of products, but thinking about how to build on the value chain from production to demand. Improve light quality.
