Abstract
A resonator for use in microwave lighting apparatus includes a mesh portion formed in a cylindrical shape with one side opened, at least one portion of which prevents microwave transmitted through a waveguide from leaking and light radiated from a light bulb is transmitted outwardly, the mesh portion being formed integral without a joint. Since the portion of the mesh structure is integrally formed as one body without a joint rather than being welded to be coupled, the microwave is prevented from leaking. In addition, since the holes of the mesh portion are uniformly formed without any clogged portion, the light transmittance area is enlarged, improving the light efficiency of the lighting apparatus.
Claims17
A resonator for use in microwave lighting apparatus having a cavity with one side opened, and a mesh portion formed at one portion of wall of the cavity, so as to prevent microwave being transmitted through a waveguide from leaking and transmit outwardly light radiated from a light bulb,
- wherein the mesh portion is formed integral without a joint therein.
A resonator of a microwave lighting apparatus includes an opening portion formed connected to a waveguide at one side of a cylindrical portion and a clogged front portion at the opposite side of the opening portion, a mesh portion is formed at the cylindrical portion and the front portion and connected through a fixing member, the mesh portion is integrally formed without a joint.
A method for manufacturing a resonator of a microwave lighting apparatus comprises the steps of:
- forming a cylindrical resonator with one side opened and the other side clogged by using an electro-forming method to have a mesh structure without a joint;
- and
- heat-treating the resonator to reinforce its strength.
A method for manufacturing a resonator of a microwave lighting apparatus comprising the steps of:
- forming a cylindrical body with both sides opened by using an electro-forming method to have a mesh structure without a joint, separately fabricating a front portion in a mesh structure, attaching it to one side of the cylindrical body to form a resonator;
- and
- heat-treating the resonator to reinforce its strength.
