Wherein, bulb portion 5 by make with quartzy or pottery and inner pack into can be by the illuminating part 5a of the luminogen luminescent substance of microwave, be welded on the bulb portion 5 and and constitute to the shell 1 inner 5b of connecting shaft portion that prolongs; In addition, bulb portion 5 also has by bulb motor 10 makes illuminating part 5a produce rotation, thereby makes its luminous uniform structure.
In having the existing microwave illuminating apparatus of said structure, connection along with external power source, magnetron 2 produces microwave, the microwave that magnetron 2 produces is excited the illuminating part 5a of plasma bulbs portion 5 by the conduction reflection of waveguide 4 and cup-shaped grid cover 6, illuminating part 5a sends light thus, the light that illuminating part 5a produces passes cup-shaped grid cover 6 again through concave mirror 7, thereby realizes the function of microwave illuminating apparatus.
When having microwave plasma illuminating device work now, can produce a lot of heats from parts such as magnetron 2, waveguide 4, transformers 3, and the method for cooling heat dissipation is with cooling fan assembly and fin as shown in Figure 1.But the reflection of 6 pairs of microwaves of cup-shaped grid cover can not all concentrate on the illuminating part 5a that has luminescent substance in the bulb portion 5 in the existing microwave plasma illuminating device, therefore exists microwave energy all not utilize, the problem that energy utilization rate is low.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing product, the invention provides a kind of microwave plasma illuminating device.Its grid are covered with to be counted spheroidal and the bulb with luminescent substance (illuminating part) is set in its center, so that the grid cover of spheroidal improves microwave energy and energy utilization rate to the illuminating part that the reflection of microwave all concentrates in the bulb portion.
The technical scheme structure of microwave plasma illuminating device of the present invention includes: be installed on a side in the shell, be used to produce the magnetron of microwave; Be installed on the shell front end, in have luminescent substance to pass through microwave action and alight bubble portion; The waveguide that the microwave that connection microwave exit of magnetron and bulb portion produce magnetron conducts to bulb portion; Be installed on the interior side in addition of shell and provide high-tension transformer to it for making magnetron produce microwave; Be installed in the bulb portion rear side shell and be connected with bulb portion with connecting shaft portion and rotate bulb portion and make luminous uniform bulb motor; Be installed on that the bulb portion rear side can be passed by microwave and with the eyeglass of light reflection; Be installed on the fan component and the fin of shell one side and surface cool magnetron, waveguide, transformer generation heat; Above-mentioned each unit construction is installed together and appearance has the shell of fin, it is characterized in that: with the bulb portion be the center also design and installation the spherical grating cover of microwave reflection is arranged, the spherical grating cover outside is installed concave mirror and is constituted.
Its spherical grating cover is connected on the shell on the end shield seat with screw socket or tight fit, and spherical grating cover is with microwave reflection and the good hexagon mesh design of printing opacity.
The present invention can install to be arranged in the microwave oven and promptly share a microwave source with microwave oven, its light that excites by be installed on optical cable interface on the oven walls, be plugged in the optical cable interface optical cable, light harvesting bubble, the snoot of end throw light in addition to be connected in optical cable.
The present invention also can install separately as required the use of throwing light on is set.
Operation principle of the present invention is as follows: energized transformer, magnetron, bulb and fan electromotor get, thereby magnetron work produces microwave, microwave conducts to the bulb portion that is all reflexed to its center in the spherical grating cover by the grid cover of sphere via waveguide, make the illuminating part plasma that has luminescent substance in the bulb and emit visible rays, pass the grid cover by the reflecting optics reflection and concentrate parallel ejaculation to realize the function of microwave plasma illumination through concave mirror again; The bulb portion of bulb motor rotation simultaneously makes the bulb portion luminescent substance evenly be intensified by microwave and evenly emits light, grid cover owing to sphere among the present invention can all reflex to microwave its center bulb portion, fully intensify the luminescent substance in the bulb, so improved microwave and energy utilization rate.
Advantage and good effect: the grid of microwave reflection are covered with and count spheroidal among the present invention, its center is provided with the bulb with luminescent substance (illuminating part), makes the microwave of spherical grating cover reflection all concentrate on the illuminating part in the bulb so can improve microwave and energy utilization rate.
