The electrodeless lamp of flame-proof mine
Technical field
The present invention relates to the electrodeless lamp of a kind of flame-proof mine.
Background technology
HF lamp without electrodes is based on the fluorescence gas discharge and a kind of new type light source that principle combines is known in two of electromagnetic field of high frequency inductions, it is made up of high frequency power generator (being the high-frequency electrical component), power coupler and electrodless discharge bulb three parts, the high-frequency electrical component acts on the induction coil of power coupler, the power electromagnet field that this coil produces is responded to the plasma in the discharge bulb by the distribution capacity of glass bulb inner cavity cylinder, is converted into light and heat.HF lamp without electrodes with its high light efficiency, high-color rendering, life-span length, no stroboscopic, energy-conserving and environment-protective, can start, not be afraid of advantage such as vibrations and few maintenance immediately and obtain more and more widely application, be described as " green illumination " in 21st century.No. 01215488.1 patent of invention of China discloses a kind of technical scheme of typical HF lamp without electrodes, this patent adopts a top to insert the copper rod of power coupler and connects the heat abstractor of the fin of copper rod bottom as HF lamp without electrodes, and such heat abstractor is not that the HF lamp without electrodes of very high (generally being no more than 160 watts) can be competent at for power.But for the bigger HF lamp without electrodes of power, the radiating mode of this poor efficiency just can not have been satisfied the demand, because a large amount of heats of power coupler manufacturing can not in time distribute, when the heat radiation copper rod was kept long high temperature, the power misfortune was closed the magnetic core of device and coil with embrittlement and very fast damage.Therefore, prior art is owing to exist the bottleneck problem of heat radiation, and the power of HF lamp without electrodes can not be done too greatly, thereby has limited the range of application of HF lamp without electrodes.

The specific embodiment
As Figure 1-3, the electrodeless lamp of the described a kind of flame-proof mine of the embodiment of the invention, comprise loam cake 1, bottom 2 and lampshade 3, described loam cake 1 connects small shell 4 by screw, the corresponding position, both sides of small shell 4 inside is provided with rubber ring 5, small shell 4 both sides are by the horn mouth device 6 that is threaded, rubber ring 5 inside are stretched in the end of horn mouth device 6, be provided with baffle plate 7 between horn mouth device 6 and the rubber ring 5, be provided with back-up ring 8 between baffle plate 7 and the horn mouth device 6, the bottom of small shell 4 is connected with big housing 9 by screw, big housing 9 inside are provided with ballast 10, the bottom of big housing 9 connects bottom 2 by screw, the both sides of bottom 2 are provided with projection, two projectioies on the bottom abut against on the inwall of big housing 9, the front surface and the rear surface of big housing 9 outer walls are respectively equipped with nameplate 15 and nameplate 16, big housing 9 is outer by the fixing tension disc 17 of screw, bottom 2 lower ends connect guard 11 by screw, be provided with lampshade 3 in the guard 11, lampshade 3 is fixed on the bottom 2, bottom 2 middle parts connect electric installation 12 by screw, and electric installation 12 middle parts connect electromagnetic wand 13, and electric installation 12 is provided with fluorescent tube 14.Described horn mouth device 6 connects and composes cable entry with small shell 4.Described lampshade 3 adopts high boron glass to make.The mesh diameter of described guard 11 is less than 50mm, and guard adopts steel bar to be welded.
Its principle of luminosity is: behind the supply voltage of input certain limit, radio-frequency generator produces 2.65MHZ high frequency constant voltage and gives power coupler, in the discharge space of glass bulb, set up the static high-intensity magnetic field by power coupler, atmosphere in the discharge space is carried out ionization, and produce strong ultraviolet light, the three primary colors fluorescent powder of glass inner wall is subjected to strong uv light induction luminous.In power supply design, owing to adopt APFC power supply control technology and adopt the IC technology, make the power factor of power supply on the one hand up to more than 0.95; Make radio-frequency generator light a lamp with the high frequency constant voltage all the time on the other hand.So when the supply voltage of input fluctuateed within the specific limits, its luminosity was all constant.
Horn mouth device 6 is the devices that allow that one or two feed cables are introduced lamp interior and can guarantee its type of explosion proof construc tion, and its inside is provided with sealing gasket and rubber seal, is used to prevent that cable is stretched or reverses and have influence on connector; Loam cake 1 is to be convenient to the user connect the device of feed cable for the electrodeless lamp of flame-proof mine; Big housing 9 is main casings of the electrodeless lamp of flame-proof mine, and it and bottom 2 have been formed the electric main chamber of the electrodeless lamp of flame-proof mine, and the high frequency ballast 10 of the electrodeless lamp of flame-proof mine is fixed in its inboard; The upper end of bottom 2 connects big housing 9, and the power coupler of high-frequency pole-free lamp source has been fixed in the lower end, and it still is the attaching parts of light source fluorescent tube and radio-frequency generator; The upper end of the electrodeless lamp of flame-proof mine is the wiring chamber, and the middle part is main electric apparatus room, and the lower end is the light source luminescent chamber; Three parts have been formed flameproof enclosure jointly, have created the internal environment of a flame proof, airtight, moistureproof, shock resistance and printing opacity for the electrodeless lamp of flame-proof mine.
This product has that luminosity is big, efficient is high, long service life, does not have again stroboscopic, characteristics easy to maintenance. Can use in the environment that has gas or coal dust explosion hazard under coal mine, main haulage roadway, shaft station, chamber, return aircourse coal preparation plant illuminator lamp also can use in industries such as metallurgy, building materials, chemical industry and need use the local illuminator lamp of antiknock device.
