Dimmer Li080

• Dimmers are used to adjust the light intensity of

incandescent and halogen light bulbs.

• They use the principle of phase cut (reverse + forward).
• Dimmers only have a two wire connection to replace an
• rdinary on/off switch.

Phase Cut

• Forward cut = good for
• hmic and inductive

loads

• Reverse cut = good for
• hmic and capacitive

loads

HID Lamp Ballast Controller

• HID or CDM lamps are as close as artificial light can get

to real sunlight

• HID and CDM are the artificial light source with the

highest efficacy (Lm/W)

• They are used for galleries, museum, display, aquarium,

theater, projectors, floodlights … lighting

What are HID Lamps

• HID lamps are high intensity discharge lamps with a

plasma burning in a halogen gas mixture

• They require a special lamp ballast to control ignition and

power

LED Drivers

• LED lighting has many advantages

➔ Immediate turn on time ➔ Longevity ➔ Efficiency ➔ Freedom of design

• LED lighting is now used for all kinds of industrial and

commercial lighting applications

➔ Light bulb replacement ➔ Display Backlighting

Why LED Drivers?

• DC Supply => a resistor is enough?
• AC Supply => a capacitor is enough?
• A simple resistor or capacitor is the cheapest solution to

limit the current over the LED string

• However, an LED driver is needed, when

➔ Highest efficiency ➔ Highest LED lifetime ➔ Full protection and ➔ Wide operating area is desired
