Price Comparison
In the price comparison, the Aluminum PCB is more pricey than FR4, as well as even more exceptional in efficiency. Thermally Conductivity Comparison Light weight aluminum PCB has a terrific capacity of thermally conductivity compared to FR4 which makes them play an essential role on LED illumination innovation. Technology Practices The thermal conductivity dielectric product of Aluminum PCB is a thermal bridge that attaches the components and also steel plate. It could transfer warmth to the heat sink through the core immediately. An Aluminum backed PCB is put together with light weight aluminum support, extremely thermally conductive dielectric layer as well as standard circuit layer. The circuit layer is a slim PCB bonding to the aluminum support. When It Comes To FR4 PCB, it takes normal machining practices: drilling, transmitting, v-scoring, countersink counterbore. So it needs an extra warmth sink to perform heat in from the circuit layer. Or it will a prospective damaging hotspots.

This is a COBs LED used in lorry headlight revealed as above. COB supplies high source of light result, each chip can reach 2000-3000 lumen. COB light-spot is a full surface source of light but not a linear light source. Even it uses porcelains with good thermal conductivity or superconducting light weight aluminum as the substratum, bordering the beautiful area right into strips, because of the limitations of the plan, COB LEDs still could not achieve the application goals on vehicle lighting for tiny dimension, high current as well as high dependability.
The car led front lights made use of COBs LED, is simple to triggered scatted light when the emitted-light go beyond the main light releasing area of 1-1.2 mm, due to the fact that its light releasing surface is larger too much compared to halogen filament. That could not raise efficient lighting driving on road; but will trigger spectacular to approaching website traffic. Although the cost of COBs LED headlight economicals, the beam is poor, it is not reliable working in high present for long period of time. |
