Abstract
An electrodeless lighting system is disclosed. A rectangular wave guide is bent substantially at a right angle, and a magnetron and a resonator are disposed at one side based on a wave guide space of the wave guide, thus reducing the space between the magnetron and the resonator and removing an unnecessary space within a casing to reduce the size of the electrodeless lighting system. Accordingly, the amount of space required for installation of the electrodeless lighting system can be reduced and the installation process can be simplified.
Claims8
An electrodeless lighting system comprising:
- a magnetron;
- a wave guide having a wave guide space to communicate with the magnetron;
- a resonator coupled to the wave guide to communicate with the wave guide space of the wave guide;
- an electrodeless bulb disposed within a resonating space of the resonator;
- and
- a bulb motor installed between the magnetron and the resonator, the bulb motor being configured to rotate the electrodeless bulb,
- wherein the wave guide includes a first wave guide part to which the magnetron is coupled and a second wave guide part to which the resonator is coupled, and a wave guide space of the first wave guide part and a wave guide space of the second wave guide part are bent to communicate with each other,
- wherein the second wave guide part is bent in a direction in which the magnetron is coupled to the first wave guide part, and
- wherein the magnetron is communicatively coupled to the first wave guide space in a direction perpendicular to a direction in which the resonator is communicatively coupled to the second wave guide space.
