Electrodeless lamp and lamp bulb therefor

A bulb for an electrodeless lamp comprising:

• an envelope through which the light can be permeated;
• a filled material filled in the envelope for emitting the light as being excited by high frequency energy;
• and
• buffer gas, wherein the buffer gas comprises first buffer gas selected from a group including Ne and Xe, and second buffer gas including Ar having a partial pressure less than 1% of the partial pressure of the first buffer gas in order to reduce a discharging voltage and lighting time.

An electrodeless lamp comprising:

• a microwave generation unit for generating microwave;
• a waveguide unit coupled to the microwave generation unit for transmitting the microwave generated from the microwave generation unit;
• a resonance unit connected to the waveguide unit for resonating the microwave which is transmitted through the waveguide;
• and
• a bulb unit disposed in the resonance unit for emitting light as being excited by the microwave,
• wherein the bulb unit comprises:
• an envelope through which the light can be permeated;
• a filled material filled in the envelope for emitting the light as being excited by high frequency energy;
• and buffer gas, comprising first buffer gas, and second buffer gas having a partial pressure less than 1% of the partial pressure of the first buffer gas in order to reduce a discharging voltage and lighting time.
