LED lighting: choosing the components
An LED luminaire or driver divides into the driver stage, the light engine, isolation, protection and control. This guide shows which J.P. Electronics manufacturer lines serve each block.
Which of our lines serves each block?
| Block | Our lines | What decides the choice |
|---|---|---|
| Driver & control ICs | On-Bright Chipown | Dimming method, power factor, integration |
| LEDs | Everlight | Efficacy, CRI, binning, package |
| Isolation & feedback | Everlight Cosmo | Isolated or non-isolated topology |
| Protection & discretes | Bel Taiwan Semiconductor Good Ark | Surge class, thermal derating |
| Passives | CCTC | Ripple current at elevated temperature, lifetime |
| Smart control MCU | Megawin Microchip | Dimming protocol, connectivity, touch control |
What usually fails first in an LED driver?
The electrolytic capacitor, from ripple current at temperature. Capacitor choice and thermal layout decide driver lifetime more than any semiconductor does, which is why the passives on the BOM deserve the same attention as the controller.
Isolated or non-isolated driver?
Class II luminaires with no user-touchable metal can use non-isolated topologies and save cost. Anything a person can touch during relamping needs isolation. The standard applicable in the target market decides, before any component does.
