As the electric ballast is divided over multiple layers the problem of a heat management for the electric ballast becomes less important.

The resistive interconnect layers (102) add a ballast resistance to the electroluminescent device such that no additional electric ballast is needed.

The lamp and beam generator is made from electrical components found in a household hair dryer including a housing (12) and a trigger switch (19) with the housing having a body portion 15 containing electrical ballast components.

An electric or electronic ballast is provided in the lighting device, a suitable electric supply to a fluorescent lamp or light bulb being ensured by said ballast.

An electrical ballast is necessary to operate HID lights, while LEDS cab be directly connected to any outlet.

The role of the electrical ballast is to limit the amount of electrical current running into the electronic device.

Using an electrical ballast allows the T5 bulbs to run cooler and last longer because it is so energy efficient.

An electrical ballast system having a toroidal current transformer having a core with a gap of predetermined dimensions, a primary winding, and a secondary winding.

A ballast generates an electrical discharge current independently of an electrical heating current.

The ballast provides an electrical current to the lamp.

As the electric ballast is divided over multiple layers the problem of a heat management for the electric ballast becomes less important.

The lamp system comprises a ballast unit which controls electrical power received from an external power source.

Ballast is connected to the discharge electrodes and a power supply.

Said diodes are associated with a ballast (3) for electrical power supply.

Device (70) or system (90) can implement a digital ballast (120) that determines an average power consumption of the digital ballast (120) drawn by a power interface (121) of digital ballast (120).
