The working principle and advantages and disadvantages of COB LED

2023-07-31 122

No new principles were developed on the basis of COB-LED. The same p-n junction of gallium arsenide, indium phosphide or other materials. The same as elementary charge recombination that emits light quanta when a DC voltage is applied. The same monochromatic light with a narrow spectrum. Same principle for obtaining inaccessible colors - when power is applied, the emission of the LED (in the optical range or UV) initiates the glow of the phosphor. This well-known method allows you to achieve colors that cannot be achieved by directly emitting semiconductor transitions. Thermal issues haven't gone away either. The novelty of the element - only in terms of production technology, it allows you to bring luminous devices to a new level of consumption.

pros and cons:

advantage:

High-density crystals on a substrate, allowing you to get a light source close to a point

Uniformly glowing surfaces without a single point

The smallest volume under the same power

Reduced production costs for individual light-emitting elements (due to lack of leads and ceramic substrate) and matrices

shortcoming:

Even if one element fails, the matrix is completely unrepairable

Sensitivity to mechanical stress during installation - adhesives, compounds, conductive layers crack after a while due to misalignment and the forces associated with it, and the substrate becomes inoperable
