3. The light quality advantage
Traditional SMD encapsulation by patch will be in the form of multiple discrete components on the PCB form LED application source component, it exists some light, glare and ghosting. And because COB encapsulation is integrated encapsulation, surface light source, perspective and easy adjustment, reduce the loss of light refraction.
4. The application advantages for daylight COB (for example)
Can be seen from the above out the SMT and COB light source in the application end of reflow soldering process, greatly reduces the application side production and manufacturing process, saves at the same time the corresponding equipment, manufacturing equipment investment cost is lower, the production efficiency is higher.
At present to make 1.2 m 2000 lm daylight lamp, for example, about 288 PCS 3528 light source, the SMT cost about 0.01 yuan RMB/PCS, a 1.2 m tubes for patch
288 * 0.01 = 0.01 RMB, such as using the COB light will save the cost.
5. Cost advantage
(1) in 1.2 m tubes, for example (light source)
lots
Can be seen from the table above, use the COB light, the whole lamp 1600 lm project cost can be reduced by 24.44%, the whole lamp 1800 lm project cost can be reduced by 29%, the whole lamp 2000 lm project cost can be reduced by 32.37%.
(2) to make the 7 w bulb light/tube light, for example (light source for the 6 w)
Can be seen from the above than using traditional SMD lamps use COB cost can be reduced by 19% to 32%, thus can greatly reduce the cost of LED products, will be conducive to the popularization of LED lighting as soon as possible.
Conclusion:
Use COB light than using traditional SMD encapsulation light has five advantages, in the light the production efficiency, thermal resistance, light quality, applications, have significant advantages on cost, comprehensive cost can be reduced about 25%, and the use of the device is simple and convenient, simple technological process.
