Cob integrated light source is chip on board, bare chips are glued to the Interconnect substrate with conductive or non-conductive adhesive, and are welded with the golden wires together, which realizes an electrical connection.
The features of COB integrated light source as following:
1. Through free collocation and combination, they can be a variety of LED lamps with easy assembly2. High reliability, no dead lamp, no plaques.
3. Uniform and downy light , no glare, no hurt to eyes
4.high CRI, high luminous efficiency
5. In normal current, minimum attenuation, which is below 3% within 1000 h
6. Safe and reliable, all work under 50 v, take full consideration for certifications of the applications
7. Environmental protection, no pollution
cob light source is the high photosynthetic efficiency integrated surface light source technology that The LED chip directly paste on the mirror metal substrate with high reflective rate without the concept of stents, Electroplating, reflow soldering and SMT process, so it reduce the one-third of the working procedure and cost.
COB light source can be as simple as high power integrated surface light source, it can be designed the light area and the overall dimensions, according to the appearance structure of products.
Products features:The electrical stability, the designs of circuit, optics and heat dissipation are scientific and reasonable By using heat sink technology, the LED definitely has industry-leading thermal lumen maintenance ratio (95%).
It is very convenient for secondary optical accessories of products and improving the quality of lighting;
high CRI, Uniform light , no glare, Healthy and Eco-friendly installing simply , using easily, reducing the design difficulty， saving the cost of processing and follow-up of lamps
There are two main forms for bare chip technology: one is COB, another is Flip Chip.COB, Semiconductor chip handover mount on the printed circuit board, bare chips are glued to the Interconnect substrate with conductive or non-conductive adhesive, and are welded with the golden wires together, which realizes an electrical connection and covered with resin to ensure reliability COB integrated light source is widely used in led bulb, led cup, led spot light, led down light, led ceiling light, LED Bean gallbladder, etc. they are currently one of the mainstream trend of LED lighting light source.
