Abstract
Microwave sulfur lamp includes microwave source of transmitting out microwave, bulb shell made from quartz, and mesh cover sheathed outside the bulb shell. Outline of the quartz bulb is columned, and the bulb is on the same axis of the said mesh cover. Thus, field intensity coupled from energy of microwave sent from microwave source is distributed on coaxial line of the mesh cover. Outline of the bulb is consistent to outline of inner distribution of field intensity so as to absorb energy of microwave as more as possible. The invention enhances capability of lamp to absorb energy coupled to microwave so as to raise use ratio of energy and increase optical efficiency.
Description
Technical field
The present invention relates to a kind of microwave sulfur lamp that improves energy coupling field intensity.
Background technology
Fig. 1 is original microwave sulfur lamp system and device and schematic diagram, the operation principle of general microwave sulfur lamp system is that the magnetron 6 in the microwave sulfur lamp produces microwave under high direct voltage drives, be transferred to resonant cavity by waveguide 5, microwave is coupled with the sulfur plasma that is contained in the quartz bulb shell 6 in resonant cavity, excites sulfur molecule to carry out radiation.In order to make the uniform steady operation of plasma, quartz bulb shell 6 drives and high speed rotating by motor 7.
The field strength distribution of the energy of microwave coupling is on the coaxial line of guard 8, but quartz bulb shell 6 but in its geometric center, capacity usage ratio is not high, causes optical efficiency not high.Fig. 2 is original guard shape and energy coupling schematic diagram thereof, and its integral energy coupling field intensity distribution shape is a cylinder.Circular bulb is positioned at its center, and energy is coupled schematic diagram as shown in Figure 2, and its energy field is distributed as cylindrical shape, is unfavorable for the absorption of energy, causes energy utilization rate on the low side.The field strength distribution of the energy of the microwave in microwave sulfur lamp coupling is on the coaxial line of guard, but bulb but in its geometric center, like this field intensity very major part do not have carrier consumption, by free waste, capacity usage ratio is not high, causes optical efficiency not high.
Summary of the invention
For solving the problem in the above-mentioned technology, the objective of the invention is to solve the low problem of energy coupling efficiency of prior art, and change bulb-shaped becoming and the consistent external form of the inner field strength distribution of guard, absorption microwave energy as much as possible strengthens luminous efficiency.
For achieving the above object, the technical solution used in the present invention provides a kind of microwave sulfur lamp that improves energy coupling field intensity, include magnetron, the quartz bulb shell that sends microwave, the guard that is enclosed within the quartz bulb shell outside, wherein: the profile of described quartz bulb shell is a cylindrical shape, with described guard on same axial line, the field strength distribution that makes the microwave energy coupling that described microwave source sends is on the coaxial line of described guard.
It is bulb-shaped that effect of the present invention is that the appearance of novel quartz bulb shell has changed, become and for the consistent external form of inner field strength distribution, absorption microwave energy as much as possible strengthens optical efficiency, and the field strength distribution of energy coupling that is the microwave in the microwave sulfur lamp is on the coaxial line of guard.For having strengthened bulb the absorbability of microwave coupling energy is improved rate of energy, strengthened optical efficiency.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the microwave sulfur lamp of raising energy of the present invention coupling field intensity.
The structure of the microwave sulfur lamp of raising energy coupling field intensity of the present invention is to include magnetron 6, the quartz bulb shell 2 that sends microwave, the guard 8 that is enclosed within quartz bulb shell 2 outsides, the profile of described quartz bulb shell 2 is a cylindrical shape, with described guard 8 on same axial line, the field strength distribution that makes the microwave energy coupling that described magnetron 6 sends is on the coaxial line of described guard 8.
The operation principle of this system is as follows: magnetron produces microwave under high direct voltage drives, be transferred to resonant cavity by waveguide, and microwave is coupled with the sulfur plasma that is contained in the quartz bulb shell in resonant cavity, excites the sulfur molecule radiation.In order to make the uniform steady operation of plasma, quartz bulb shell passes through driven by motor and high speed rotating.
Fig. 3 is original guard shape and energy coupling schematic diagram thereof, and the guard 8 of microwave sulfur lamp is metal net shaped structure, and there is the hole of 2-3mm the centre, and its global shape is a cylinder.Quartz bulb shell 2 is positioned at its center, and energy is coupled schematic diagram as shown in Figure 3: its energy field is distributed as cylindrical, and it is spherical comparing bulb, then helps the absorption of energy.
Fig. 4 is a microwave sulfur lamp quartz bulb shell shape schematic diagram of the present invention.
The microwave sulfur lamp of raising energy coupling field intensity of the present invention is achieved in that
The present invention is the improvement to the quartz bulb shell shape of microwave sulfur lamp; promptly; to be spherical quartz bulb shell originally; now change Design Thinking quartz bulb shell is processed into columniform quartz bulb shell 2; but its inner space constancy of volume; the component ratio of inside stuffing is also constant, can protect its characteristics of luminescence effectively like this, and making the field strength distribution of the energy coupling of the microwave in the microwave sulfur lamp is on the same axis of guard 8.Because quartz bulb shell 2 is located at its geometric center, with guard 8 on same axial line, like this field intensity very major part do not have the energy utilization of carrier consumption then to use, improved luminous efficiency.The appearance of the bulb of novel quartz bulb shell has changed bulb-shaped, becomes and the consistent external form of the inner field strength distribution of guard, and absorption microwave energy as much as possible has strengthened luminous efficiency effectively.
