When the depth of the coupler 30 inserted into the accommodating chamber 21 is greater, the magnetic field generated by the coupler 30 in the sealed lamp housing 20 is greater, and thus the brightness of the visible light generated is greater. Conversely, when the depth of the coupler 30 inserted into the accommodating chamber 21 is small, the magnetic field generated by the coupler 30 in the sealed lamp housing 20 is small, and thus the brightness of the visible light generated is small. Therefore, by using the adjusting module 40 to change the insertion depth of the coupler 30 into the accommodating chamber 2l, the electrodeless lamp 1 of the present invention can change the brightness of the lamp 1 according to actual needs, so that the practicability and convenience can be increased.

On the other hand, since the electrodeless lamp 1 of the present invention can adjust its brightness, the manufacturer does not need to produce electrodeless lamps with different brightnesses. Only one electrodeless lamp can produce a variety of different brightnesses, so the manufacturing cost can be reduced. Distributors can also reduce the types and quantities of stocks, and users do not need to purchase electrodeless lamps with various brightness levels.
