In recent years, with the intensification of market competition, the gross profit margin of LED packaging enterprises has been declining, especially the performance of traditional lighting packaging devices is more obvious. If enterprises want to break through and achieve greater value, continuous product innovation is a necessary tool for survival.

In order to meet the needs of the commercial lighting market for high signage, high reliability and low light decay COB light sources, Liyang has launched four new ceramic COB light sources: 1313 series, 1919 series, 2024 series and 2828 series, the power covers 3W to 55W, can meet the design requirements of various indoor commercial lighting fixtures, and the display finger is greater than 90, the application products under its light are full of color, strong expression, and greatly contribute to the turnover increase. Products in the initial sales has been widely recognized by the market, this series of products can be used in high-end clothing lighting, hotel lighting, decorative lighting, fresh food lighting and other fields.

　　Liyang ceramic COB light source series products have three advantages.

Advantage 1: Good insulation performance, high pressure resistance

Due to the high insulation of the substrate, ceramic COB light source products can withstand high voltage up to 4000V, good safety, can match high voltage and low non-isolated power supply, meet the product export safety certification, reduce power cost, improve power efficiency. High insulation pressure, ensure personal safety and equipment protection ability, so that the product is highly integrated and the volume is reduced.

Advantage 2: Excellent air tightness

The thermal expansion coefficient of the ceramic substrate is close to that of the silicon chip, and the grain welding will not be caused by the temperature change, resulting in attenuation and dead lamp

No insulation layer, the path of heat dissipation is copper layer →AL2O3 ceramic layer, high thermal conductivity; It is particularly good in the main indicators of hot and cold shock and circuit oxidation and vulcanization resistance.

Advantage three: high light efficiency, high finger, small color tolerance, small attenuation,

Due to the high reflection efficiency of ceramic substrate, the luminous efficiency of Liyang ceramic COB light source products can reach 120-150lm/w; The visible finger is mainly 80 and 90, the light spot is uniform, soft and full, and R9>10, no glare and zebra pattern; Color tolerance less than 3, color consistency is good; 10000 hours light decay is less than 2%.

With the change and innovation of packaging technology, in addition to the original traditional indoor lighting market, high-power ceramic packaging has also begun to gradually penetrate into automotive headlights, Flash LED, UV LED and other fields. Thus, its prospects look very promising.
