LED - Technical Notes

A DOB "driver-on-board" LED light is an LED lighting system (either an LED bulb or an LED luminaire) that incorporates a light engine (driver-integrated LED assembly intended to operate directly on line voltage power) with an integrated on-board driver.  In conventional LED lighting systems the driver is typically separated from the LED assembly and fabricated on an FR4 printed circuit board (PCB). This configuration is based on the consideration that LED drivers have been dominantly designed as switching mode power supplies. SMPS drivers typically make use of bulky, expensive and unreliable reactive components such as inductors and capacitors. The use of reactive components necessitates a dedicated FR4 board which provide adequate routing layers for component interconnects. In an integrated lighting system, the considerable volume of a typical SMPS driver creates a need for an adequate space within the lighting system in order to accomm...

LED light bulb  produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps.                          We can put LED bulbs in regular lighting fixtures.  This includes fixtures that have previously used incandescent bulbs or CFL bulbs. After all, LED light bulbs are intended to replace old light bulb designs that are less energy efficient. Be sure to choose an LED bulb with a base, shape, and wattage that is compatible with the fixture. As LED bulbs are being manufactured in every possible design, it should easy to find the right fit for your lamp or chandelier. There are 2 types of LED Bulbs Driver LED bulb In these types of Bulb, a separate driver circuit is used for power supply. LEDs are mounted on separate chipset. DOB ( Direct On Board...
