The present invention relates to a 3-way halogen light bulb.
Incandescent 3-Way light bulbs have been a popular product in the marketplace for many years because they offer the user the choice of three levels of light from one light bulb.
The incandescent 3-way light bulb consists of two filaments, a major and a minor. When used in a 3-way lamp socket, the contact point in the socket moves its position to make contact with the base of the light bulb at different locations. This change in locations will electrify each filament in turn, then both together. For example: A 3-way bulb rated at 30/70/100 watts utilizes a 70 watt major filament and a 30 watt minor filament. By switching the socket, first the 30 watt filament is electrified, then the 70 watt, then both together.
Typically this common design for 3 way light bulbs has proven to be a somewhat sensitive construction. This design is known for its early failure of at least one filament due to the constant switching of the filaments on and off and the limited supports to secure the filaments.
The present invention solves the problems described above, plus offers a new alternative in 3 way lights that has not been available previously. The present invention relates to a 3 way halogen light bulb. It is an object of the present invention for the three way halogen light bulb to comprise two halogen capsules. It is an object of the present invention to produce more lumens per watt than standard incandescent 3 way bulbs. It is an object of the present invention for the 3 way halogen light bulb to maintain their full light output during the course of their life. The standard 3-Way bulb's light output depreciates dramatically during its life cycle. It is an object of the present invention for the halogen capsule's filament structure to be substantially more stable than its standard incandescent counterpart, ensuring a long life. It is an object of the present invention to provide a 3 way halogen light bulb that lasts up to 4000 hours.
It is an object of the present invention to provide a halogen light produced by the 3 way halogen light bulb which delivers a crisp white light which is uplifting, pleasant and excellent for reading as well as rendering colors more accurately.
The present invention comprises a 3 way halogen light bulb. The present invention comprises a three way halogen light bulb having two halogen capsules. The three way halogen light bulb of the present invention produces more lumens per watt than standard incandescent 3 way bulbs while maintaining their full light output during the course of their life. The 3 way halogen light bulb of the present has a halogen capsule's filament structure which is substantially more stable than its standard incandescent counterpart, ensuring a long life. The 3 way halogen light bulb of the present invention lasts up to 4000 hours.
The 3 way halogen light bulb of the present invention provides a halogen light which delivers a crisp white light which is uplifting, pleasant and excellent for reading as well as rendering colors more accurately.
