COB LED advantages:
POSTED ON AUGUST 12, 2013 BY ADMIN IN LED COMPONENT, LED KNOWLEDGE WITH 10 COMMENTS
COB light source can save about 30% cost in the application, mainly lie in LED package cost, light engine production costs and the secondary light distribution costs, which is great significance for applications and promotion of semiconductor lighting.
In performance, through the rational design and micro-lens molding, COB light module can avoid the defects of point and glare light also other flaws existed in discrete light source device. It also can add some red chips appropriately, so that to improve the CRI effectively under the condition of without reduce light efficiency and lifetime significantly.
In application, COB module makes production of lighting manufacturer more simple and convenient, and reduces cost effectively. In production, the existing technology and equipment can support high yield and large-scale COB module manufacturing.
With the development of LED lighting market, lighting demand is growing rapidly, according to different inquires of lighting applications, we can produce a series COB light source module for mass production.
