## Abstract

A high frequency pulse generator, a distributed parameter coupling line, a sequential pulse variable voltage ignition system using a standard HMI lamp or a specialized ultra high frequency HMI lamp to provide a high Color Rendering Index, to reduce or eliminate audit lamp and igniter resonance and provide for a wide range of color correction from 7000° Kelvin to 3000° Kelvin from a standard HMI lamp.

## Claims

### Claim 1

A high frequency pulse generator having a sequential pulse voltage ignition system coupled to a light source that layers variable AC voltage and variable DC voltages in sequential variable pulses to ignite the light source at substantially the lowest possible voltage.

### Claim 2 (depends on 1)

The high frequency pulse generator of claim 1 including a sensing ignition circuit that terminates the ignition sequence of the light source when current to the light source stabilizes.

### Claim 3

The high frequency pulse generator of claim I wherein the color temperature of the light source is substantially controlled by user selected current and voltage characteristics input to the light source that are selected based on the operational characteristics of the light source.

### Claim 4 (depends on 1)

The high frequency pulse generator of claim 1 further comprising a high frequency lamp wherein the light source is secured to an electrically conductive frame of metal strips.

### Claim 5 (depends on 1)

The high frequency pulse generator of claim 1 wherein, the light source includes a plurality of electrically conductive rods adapted to be secured to a complementary shaped conductive surface.

### Claim 6 (depends on 1)

The high frequency pulse generator of claim 1 with the light source operatively connected to electrically conductive flat plates adapted to be secured to a complementary shaped conductive surface.
