Problems solved by technology
[0009] But the problem in the electrodeless lighting device of the prior art as mentioned above is: as said above, since the bulb 5 and the connection part 15 are connected together with an adhesive, when the bulb 5 produces When the high temperature above 1000°C is transmitted to the part connected to the connection part 15 through the shaft part 5b, the adhesive will be melted, and the bulb 5 may fall off from the connection part 15 during this process, so that the transmission of power cannot be realized smoothly.
[0010] That is, if the adhesive bonded to the connecting portion of the connection member 15 and the shaft portion 5b of the bulb 5 melts, the rotational force generated by the bulb motor 10 cannot be sufficiently transmitted to the bulb 5
Accordingly, if the bulb 5 cannot be rotated smoothly, not only the power of the bulb motor 10 will be lost, but also the cooling effect of the bulb 5 will be significantly reduced.
Since the life of the expensive bulb 5 is shortened and needs to be replaced frequently, there is a problem of high capital consumption.

Embodiment Construction
[0041] 3 and 4, it can be seen that the bulb shaft connection device of the electrodeless lighting device of the first example of the present invention is connected to the bulb motor 10 by the motor shaft 15 having the external thread 21 formed on the outer surface of the bulb motor 10 and the bulb 5. The bulb shaft 5b inserted into the connecting member 20, the fixing nut 30 connected to the connecting member 20 to connect the connecting member 20 and the bulb shaft 5b to each other, and the inner surface of the connecting member 20 and the outer surface of the bulb shaft 5b are inserted. The inner ring 40 between them is formed.
[0042] The motor shaft 15 and the connecting member 20 are assembled by means of screw connection S.
[0043] The connecting member 20 has a tubular shape so that the motor shaft 15 and the bulb shaft 5b can be connected by inserting both ends thereof.
[0044] In order to enable the fixing nut 30 to be firmly connected, an external thread 21 is f...

A lamp axis connecting device of a no-electrode illuminating device is composed of connection components, fixed nuts and an internal ring, in which, a male thread is formed at the cone outside wall at one end of the connecting part inserted by the lamp axis, the end of the lamp axis plug hole forms a ring mounting part, the other end center forms internal threads screwed with the motor axis, a fix nut forms internal threads on the lower part inside wall screwed with the connecting part and its upper part inside wall forms a cone face and the lamp axis diameter hole is set at the top, the internal ring is a thick ring with the central hole larger than the lamp axis and a notch.
Description
technical field [0001] The present invention relates to an electrodeless illuminating device utilizing microwaves, in particular to its bulb shaft connecting device. Background technique [0002] As shown in FIG. 1 , the prior art electrodeless lighting device consists of a magnetron 2 installed inside a housing 1 capable of generating microwaves, a high-voltage generator 3 that converts a common AC voltage into a high-voltage output to the magnetron 2 , and The outlet of the magnetron 2 is connected to the waveguide 4 which conducts the microwaves generated by the magnetron 2, and the light bulbs 5, The front surface of the waveguide 4 and the bulb 5 is covered with a mesh screen 6 which can cut off microwaves and allow the light emitted by the bulb 5 to pass therethrough. [0003] In addition, a reflector 7 is installed on the front of the housing 1 to cover the mesh 6 so that the light emitted by the bulb 5 can be concentrated and irradiated forward. A mirror 8 that can...
