Abstract
A bulb in an electrodeless lamp system comprises a bulb unit having an envelope space in which luminous material excited by an electric field to form plasma and generate light is filled and two or more conductors installed in the envelope space so that ends of the conductors face each other.
Claims29
A bulb for an electrodeless lamp system comprising:
- a bulb unit, the bulb unit including an envelope and a supporting member for supporting the envelope, the envelope and the supporting member being a one-piece, unitary structure, the envelope defining an envelope space therein, luminous material in the envelope space being excited by an electric field to form plasma and generate light is filled, the supporting member defining a cavity space therein, the envelope having a partition separating the envelope space from the cavity space;
- and
- two or more conductors installed in the envelope space, each of the conductors having two ends, each one of the two ends of the conductors facing each other, one of the conductors passing through the envelope space and the partition into the cavity space, the one of the two ends of the one of the conductors terminating in the envelope space, the other of the two ends of the one of the conductors terminating in the cavity space.
An electrodeless lamp system comprising:
- a microwave generator for generating microwaves;
- a resonator connected to the microwave generator for resonating the microwave generated from the microwave generator;
- a bulb unit installed in the resonator, the bulb unit including an envelope and a supporting member for supporting the envelope, the envelope and the supporting member being a one-piece, unitary structure, the envelope defining an envelope space therein, luminous material in the envelope space forming plasma by an electric field formed in the resonator to generate light is filled, the supporting member defining a cavity space therein, the envelope having a partition separating the envelope space from the cavity space;
- and
- two or more conductors installed in the envelope space, each of the conductors having two ends, each one of the two ends of the conductors facing each other one of the conductors passing through the envelope space and the partition into the cavity space, the one of the two ends of the one of the conductors terminating in the envelope space, the other of the two ends of the one of the conductors terminating in the cavity space.
