On June 9, 2018, the 23rd Guangzhou International Lighting Exhibition (Canton Fair) will kick off. This LED industry event will attract relevant companies from the domestic and international LED industry chain to debut.
As the leader of domestic commercial photo COB, Zhonghao Optoelectronics is in the “epitaxial growth of GaN material on sapphire substrateâ€, “ZnO transparent conductive film epitaxial growth and high-brightness LED chip process†and “high color rendering high-power white LED light source moduleâ€. In the key common technology fields such as “encapsulationâ€, more than 40 invention and innovation technology patents have been obtained, and a series of products with independent technology and cost competitiveness have been formed.
During this year's Guangya Exhibition, Zhonghao Optoelectronics will highlight its four full-featured products: full spectrum COB, color temperature COB, special light color COB, and high power density COB. Zhonghao Optoelectronics booth is located at booth A69 of Hall 9.3.
Full Spectrum COB--"Sunshine" Series
In the field of high-end commercial lighting, the requirements for the visible portion are mainly reflected in the color rendering index. The higher the color rendering index, the more realistic the color of the object can be restored. In response to market demand, many packaging manufacturers began to focus on the development of full-spectrum LED light sources. In 2014, Zhonghao Optoelectronics took the lead in launching full-spectrum COB.
After years of research by Zhonghao Optoelectronics, this series of products has continued to evolve. According to Wang Mengyuan, general manager of Zhonghao Optoelectronics, now the new full-spectrum COB series, the color rendering index Ra can reach 95 or more, the saturation Rg value can reach 105, the fidelity Rf value reaches 95, and the object color can be truly restored. Application scenarios bring a more precise light color environment.
It is understood that the "Sunshine" series can enter the top demonstration projects, landmark projects and other applications, especially for top commercial lighting, such as high-end clothing chain stores, luxury brand stores.
Color temperature COB--"Colorful" series
Zhonghao photoelectric color temperature COB adopts the latest CSC technology, the light color is evenly distributed, the color point is fitted to the black body track, the dimming color can be adjusted, the gradient is soft, and the light color quality is relatively excellent. It is understood that the color rendering index of this series of products can reach 85, the luminous efficiency is more than 100lm/w, and it can realize the warm white to cool white color. The color temperature can be adjusted from 2700K to 6500K.
Wang Mengyuan said that the "colorful" series is mainly used in clothing stores, home lighting and other places, and is a better choice for intelligent control scenes in commercial space.
Special light color COB--"Special color" series
For the application scenarios in the high-end segmented commercial lighting field, Zhonghao Optoelectronics has launched a series of COB products. The most important features of this series of products are based on the color characteristics of the object or environment being illuminated, targeted spectral output, enhanced fidelity, subdivision and professionalism to meet the high-end lighting needs of customers.
Among them, fruit fresh lighting: bright colors give people a sense of vitality and fruitful harvest, mostly used in the fruit and vegetable parts of the fresh area. The Zhonghao light source selects a 3000K full-spectrum light source, taking into account the display capabilities of various colors (especially red, yellow, and green). In addition, there are special light sources for vegetables and aquatic lamps, and special light sources for bread lamps.
"At present, the growth rate of fresh COB products is relatively fast. Now Wal-Mart, RT-Mart, Carrefour, Tianhong and other supermarkets are using our products." Wang Mengyuan told Gaogong LED.
Fresh meat fresh light lighting: the industry's first white light fresh light source, under the premise of avoiding the influence of the supermarket light environment, the effect is bright, red and white, highlighting the tenderness of meat.
The Guangya Exhibition, Zhonghao Optoelectronics' “COLOR†series COB, can customize the color rendering index, color point, saturation, scientific formula design for lighting applications, and provide customers with professional high-end customization of chromatography and spectroscopy. Service, suitable for special applications such as fresh, catering, furniture, jewelry.
High power density COB--"HD" series
This series of products uses a car-grade high-power density flip-chip integration process, Tc temperature of up to 95 degrees, can provide near-field optical design, is the first choice for small-angle optical design.
Gaogong LED has learned that Zhonghao Optoelectronics has launched CC3460 inverted headlights "Wind" series COB, CD7940 inverted headlights "Eagle Eye" series COB, CD8044 inverted headlights "Eagle Eye" series COB, CD7950 Flip-chip lights "Eagle Eye" series COB and other products, can be applied to automotive headlights, fog lights, motorcycle headlights and other fields.
Wang Mengyuan told Gaogong LED: "Now the product direction is still to work hard on the light color index. For example, it refers to the main push 80 in the past, and now it is mainly above 90 or 95. Zhongyu insists on the consistent 'good light, good color' Product features, in 2013, began to push 90 indicators above products, including full spectrum products, such as 97 indicators, 130lm / w or more products. Currently Zhonghao Optoelectronics research and development mainly in high power density COB with high luminous efficiency and high Professional color COB for gamut saturation."
To understand the product depth information or to experience the product experience, Zhonghao Optoelectronics will display and interpret it at booth A69 in Hall 9.3.
