Why use the COB spotlight LED, COB LED downlight, COB corn LED light bulb?
If you want to ask us why to choos the COB spotlight LED, COB LED downlight, COB corn LED light bulb? But not the SMD LED lights or High power LED commercial lighting items?
COB is the latest technology of LED package with PCB board. We're going to tell you more about the Advantages of COB LEDs as below. Then you would know why you are willing to choose COB light source LED lamp.
1. COB, (Chips on Board) , multi LED (light emitting diode) chips are packaged together as one lighting module. When it light up, it looks like a lighting panel.
2. COB technology will allow the LED modules to be clusters on the circuit boards. Chips are protected and mounted directly on the circuit board. The LED dice from the wafer and places them by die and wire bonding processes directly on a printed circuit boards (PCB). A polymer layer is placed above the dice and wires for protection. Silicone is used as the polymer layer due to its low photo degradation.
3. Compare to traditional lighting such as fluorescent lamp, as it is super bright in a small size, it cause uncomfortable glare. In case of no diffused optical lens used, such LEDs usually cause glare and zebra strips . But when optical lens or cover used, it will cause light loss when LED beam pass through this lens or cover. While all the above disadvantages of traditional LED lighting can be overcome with the advent of COB LED lighting. COB LED is multi chips packaged, it can 10 times more increase lighting area, so it avoid uncomfortable glare by the maximum extent.
4. Thermal management requirements for high brightness LEDs require a very low thermal resistance system. MCPCBs are a standard building block of high brightness applications requiring thermal
management. We offer cost effective one of a kind custom solutions tailored to your thermal requirements.
5. COB technology provides significant advantages over surface mount technology (SMT) components in the design with better temperature management, smaller size of lumen packages and lower production costs.
6. In general the life span of COB LED can be 40000-50000 hours.
8. Currently COB LED Light price and High power LED Light is closer, with the COB LED Lights market share increase in the global lighting market, its price will have a competitive advantage.
