COB light source introduction
COB light source is a high-efficiency integrated surface light source technology in which the LED chip is directly attached to a high-reflectivity mirror metal substrate. This technology eliminates the concept of brackets, no electroplating, no reflow soldering, and no mounting processes, so the process is reduced Nearly one-third, the cost has also been saved by one-third.
The COB light source can be simply understood as a high-power integrated surface light source, and the light emitting area and shape size of the light source can be designed according to the shape and structure of the product.
Characteristics of cob light source
product features: cheap and convenient
The electrical properties are stable, and the circuit design, optical design, and heat dissipation design are scientific and reasonable;
The use of heat sink technology ensures that the LED has an industry-leading thermal lumen maintenance rate (95%).
it is convenient for the secondary optical matching of the product and improves the lighting quality.
High color rendering, uniform luminescence, no spot, healthy and environmentally friendly.
Simple installation, convenient use, reduce the difficulty of lamp design, save lamp processing and subsequent maintenance costs.
COB light source manufacturing process
COB (Chip On Board, COB) process is first to cover the silicon chip placement point with a thermally conductive epoxy resin (generally silver-doped epoxy resin) on the surface of the substrate, and then directly place the silicon chip On the surface of the substrate, heat treatment until the silicon wafer is firmly fixed on the substrate, and then wire bonding is used to directly establish an electrical connection between the silicon wafer and the substrate.

LED COB Light vs LED PAR Wash Light
Learn how COB fixtures and LED PAR wash lights differ in beam quality, color rendering, and stage applications.
What Is LED for Stage Lighting?
Discover why LED technology has become the standard for modern stage lighting, including energy efficiency, color control, and long service life.
Why PAR Can Lights No Longer Use Many LED Beads as Before
Understand how advances in LED chip technology have reduced the need for large numbers of individual LED beads.
What Is Bulb Light Source?
Explore the evolution of stage lighting sources, from incandescent and halogen lamps to LEDs, COB technology, and discharge lamps.
COB stands for Chip-on-Board, a packaging technology in which multiple LED chips are mounted directly onto a single substrate to form one high-power light source.
COB light sources provide high luminous efficiency, excellent heat dissipation, uniform illumination, high color rendering, and a compact design, making them ideal for professional lighting applications.
A COB light source often delivers higher brightness density and smoother light output than traditional multi-LED arrays, although overall brightness depends on fixture design and power rating.
COB LEDs are widely used in stage front lights, theater lighting, photography lighting, studio fixtures, commercial lighting, and architectural illumination where high-quality white light is required.
Most COB fixtures are designed for high-quality white light. RGB color mixing is typically achieved using multiple colored LED chips in PAR lights, wash lights, or moving head fixtures, although RGB COB technology is also available in some specialized products.
