The difference between COB light source and LED light source

COB light source can be simply understood as a high power integrated surface light source, according to the structure of the product shape design light source light area and size. COB integrated package is a more mature LED packaging, with the widespread use of LED products in the lighting field, COB surface light source has become one of the mainstream products of the packaging industry. So what is COB light source, COB light source and LED light source difference in what?

What is COB light source?

COB light source is the LED chip directly affixed to the high-reflectivity mirror metal substrate of high luminous efficiency integrated surface light source technology, this technology eliminates the concept of bracket, no plating, no reflow, no SMD process, so the process is reduced by nearly one-third, the cost is also saved by one-third.

Product features: electrically stable, circuit design, optical design, heat dissipation design is scientific and reasonable; using heat sink process technology to ensure that the LED has the industry-leading thermal lumen maintenance rate (95%). Facilitate the secondary optical matching of products to improve the quality of lighting. High color rendering, uniform luminescence, no light spot, health and environmental protection. Simple installation, easy to use, reduce the difficulty of lamp design, save lamp processing and subsequent maintenance costs.

What is LED light source?

LED light source (LED refers to Light Emitting Diode) is a light-emitting diode light source. This light source has the advantages of small size, long life, high efficiency, and can be used continuously for up to 100,000 hours, the future of LED light source applications in the lighting field has become mainstream.

The difference between COB light source and LED light source

1. Different principles

1, cob light source: LED chip directly affixed to the high reflectivity of the mirror metal substrate of high light efficiency integrated surface light source technology.

2, LED light source: the integration of computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information technology products.

2. Different advantages

1, cob light source: facilitate the secondary optical supporting products, improve lighting quality; simple installation, easy to use, reduce the difficulty of lamp design, save lamp processing and subsequent maintenance costs.

2, LED light source: low heat, miniaturization, short response time, etc., all of which make the LED light source has great advantages, creating favorable conditions for application in actual production life.

3. Light source characteristics are different

1, cob light source: high color rendering, uniform luminescence, no light spot, health and environmental protection.

2, LED light source: can be used continuously for up to 100,000 hours, the future of LED light source applications in the lighting field has also become mainstream.

4. Different fields of use

1, cob light source: mainly used in led downlight, track lights, ceiling lights and other indoor lighting above, its single maximum wattage does not exceed 50W.

2, LED light source: the main use is used to make LED flood lights, LED street lights and other outdoor lighting, the single maximum wattage can reach 500W.
