The battle for the COB market is continually fermenting, just as the industry has struggled with the SMD market in previous years.
Samsung Electronics recently announced the launch of a new generation of COBLED devices. The new D-series COB products offer higher luminous efficiency and are suitable for directional lighting applications such as various professional MR lamps, PAR lamps, commercial spotlights, downlights and high bay lights.
The new D-Series COB products offer light efficiency up to 160 lm/W (5000K CCT, 80 CRI, 85°C), a significant increase over the previous generation and a 50% reduction in thermal resistance. The introduction of new products has greatly enriched the Samsung COB product lineup, providing a wider range of light source options for directional lighting such as spotlights.
The new generation of D-series COB products offers 11 different power options, high performance and high reliability to meet DLC Premium standards requirements. (DLC is recognized as the preferred method of performance and quality for LED lighting products in North America. ).
The new products are available in a variety of CRI 70+ to 90+ color rendering indices and offer optimized chromatographic Solutions for the retail market for “high color saturation†lighting applications for many lighting designers. The need for richer and more vibrant colors in a variety of different lighting situations.
Liyang has newly launched 4 ceramic COB light sources: 1313 series, 1919 series, 2024 series and 2828 series, the power covers 3W to 55W, which can meet the design requirements of various indoor commercial lighting fixtures, and it is more than 90. The application of the product under its illumination is full of color and expressiveness, which greatly contributes to the increase in transaction volume.
The products have been widely recognized in the market for initial sales. The series can be applied to high-end clothing lighting, hotel lighting, decorative lighting, fresh food lighting and other fields.
Advantage 1: Good insulation performance and high pressure resistance
Due to the high insulation of the substrate, the ceramic COB light source product has a high voltage resistance of more than 4000V, and has good safety. It can match the high voltage and low non-isolated power supply, meet the product safety certification, reduce the power supply cost and improve the power efficiency. High insulation withstand voltage ensures personal safety and equipment protection, making the product highly integrated and compact.
Advantage 2: superior air tightness
The thermal expansion coefficient of the ceramic substrate is close to that of the silicon chip, and the grain is not soldered due to temperature change, resulting in attenuation and dead light. The heat dissipation path is copper layer → AL2O3 ceramic layer, high thermal conductivity; thermal shock resistance and circuit oxidation resistance The main indicators such as anti-vulcanization performance are particularly outstanding.
Advantage three: high light efficiency, high index, small color tolerance, small attenuation
Due to the high reflection efficiency of the ceramic substrate, the luminous efficiency of the Liyang ceramic COB light source can reach 120-150lm/w; the main push is 80 and 90, the spot is even and soft, and R9>10, no glare and zebra; the color tolerance is less than 3, the color difference is good; 10000 hours light decay is less than 2%.
Dehao Runda Packaging Division has carried out many experiments on different color points and different chromaticity parameters through experiments such as packaging process, material selection and phosphor light distribution, and launched “Special Lighting X Series COBâ€.
The X-series products can achieve a more vivid and vivid color performance and a more natural white light. With excellent spatial color uniformity and 3-step color tolerance control, different color colors can be used to achieve better "object color". "presentation effect.
The DeHao Runda X-Series COB light source has been developed in four series for the characteristics of different objects. Including clothing lighting C series, food lighting F series, furniture lighting W series and warm lighting Y series.
Jingke Electronics launched a high-efficiency AC COB of 160 lm/W last year, which is a high-performance COB series product of >95. It is based on its mature flip-chip technology and is aimed at the needs of high-end application groups (museums, art galleries, etc.). Optimize the latest results.
This is a COB with super high light quality, the color rendering index is above 95, close to 100% restore color authenticity, can meet the color reduction of different scenes, suitable for high-end, professional lighting places.
Rammings released the latest third-generation COB. The new products have world-leading light and light qualities. Under the condition of thermal measurement of 85 ° C, color temperature of 3000K, and display of 80, the luminous efficiency can reach 150LPW, which can be used in many indoor lighting applications. Under the condition of color temperature of 6500K and 70 indicators, the light effect 170LPW can be used for outdoor lighting.
With the introduction of the third-generation COB, it means that Raminness has clearly surpassed the recent release of new products in terms of product performance. Thanks to advanced packaging technology and the high-quality chip of the parent company Sanan, the new generation of COB has improved by 20% over the second generation.
The third-generation COB covers the full range of color temperatures and indicators that are popular today. The diameter of the light-emitting surface includes 9mm, 11mm, 14mm, 18mm, 22mm, and 27mm. Like all Rammings COB products, the third-generation COB is 100% fully inspected and shipped at 85°C to ensure thermal performance for indoor and outdoor applications.
Hongli Zhihui released the second AC COB new ACLE series, which has higher withstand voltage value and stability; it is compatible with some two-way thyristor dimmers to realize intelligent two-way dimming function.
The ACLE series adopts the "COB package + power package" method, the power covers 10W/20W/30W, and the size models are LE002/LE003/LE004 respectively. The product has added solder-free terminals to avoid product failure caused by manual welding, and join Surge protection, built-in over-temperature protection, withstand voltage > 4K, greatly improving the pressure resistance and stability of the product.
The product is also matched with a special plastic bracket, which is beneficial to the device protection and installation of the lamp. It is recommended to be applied to the lighting products such as downlights and spotlights for commercial/home lighting.
