Abstract
Provided is an electrodeless sulfur lamp including a power supply supplying electrical power, a transparent bulb which has a space inside it, with sulfur being contained in the space, and a coil connected to the power supply, which is wound around an outside surface of the transparent bulb and which induces electric discharge by combining magnetic fields. The exclusion of the magnetron in the sulfur lamp increase a system efficacy and saves a cost for the magnetron. Also, it is possible to prevent the coil from blocking light emitted from the main electric discharge sphere 11, because the coil is not wound around the main electric discharge sphere.
Claims14
An electrodeless sulfur lamp, comprising:
- a power supply supplying electrical power;
- a transparent bulb comprising a main electric discharge sphere which sulfur is contained inside and at least one or more subsidiary electric discharge rods formed on an outside surface of the main electric discharge sphere to be connected to and open to the main electric discharge sphere;
- and
- a coil which is wound around the subsidiary electric discharge rods and connected to the power supply to induce electric discharge by combining magnetic fields when electrical power is applied.
An electrodeless sulfur lamp, comprising:
- a power supply supplying electrical power;
- a transparent bulb comprising a main electric discharge sphere which sulfur is contained inside and a subsidiary electric discharge rod formed separately from the main electric discharge sphere, which a subsidiary electric material necessary to initially switch on light is contained inside;
- and
- a coil which is wound around the subsidiary electric discharge rod and connected to the power supply to induce electric discharge by combining magnetic fields when electrical power is applied.
