Background
The electromagnetic induction lamp belongs to a new generation energy-saving product without filaments, high luminous efficiency, high luminous flux, long service life and high power factor, and can be widely applied to families, plants, office places, roads, engineering construction sites and the like.
In a nineteen-to-nine year, the japan panasonic corporation invented Everlight electrodeless lamps, the nineteen-to-four year GE produced the courra lamp, and the nineteen-to-seven year philips developed into QL electrodeless lamps, which are based on the principle that electric energy is converted into magnetic energy by electromagnetic induction and the magnetic energy is converted into light energy to emit light, and thus they all belong to electromagnetic induction lamps, and the shapes and structures thereof are substantially the same, as shown in fig. 1, the lamp 100 includes:
a base 102 connectable to a lamp holder;
a housing 104 connected to the base 102 and having a cavity therein;
an electromagnetic induction lamp circuit disposed within the cavity of the housing 104;
a lamp tube 106, which is spherical and fixed on the outer shell 104, and inside which krypton and amalgam 108 for maintaining discharge are provided;
a glass chamber 110 with a built-in coil, fixed on the outer shell 104, extending into the lamp tube 106, and having an exhaust hole 112 at one end;
a conductive glass material 114 connected to the RF ground, connecting the lamp tube 106 and the RF ground;
a phosphor coating 116 covering the inside of the lamp tube 106, the outside of the glass cavity 110, and the portion of the lamp tube 106 connected to the conductive glass material 114;
a titanium dioxide reflective coating 118 covering the outside of the glass cavity 110 and the portion of the lamp tube 106 that is connected to the conductive glass material 114;
and a conductive coating 120 covering the outside of the lamp tube 106.
When the lamp works, the coil arranged in the glass cavity 110 generates a magnetic field, the magnetic field drives gas in the lamp tube to carry out ionization discharge to generate light, although the lamp has the advantages of an electrodeless lamp, the miniaturization is realized, and the lamp can directly replace an incandescent lamp, but the lamp has higher cost, complex process and difficult manufacture. And is limited to only low power electrodeless lamps.
Patent US 2003011322 discloses an improved electromagnetic induction lamp which separates the circuit from the lamp tube, so that in case of a damaged lamp tube, only the lamp tube is replaced, which results in a considerable cost saving. However, the lamp tube of the electromagnetic induction lamp disclosed in the patent has to have two magnetic rings sleeved on the lamp tube, and since the magnetic rings must be connected to the control circuit to work, the complexity of the connection circuit of the two magnetic rings is increased to a certain extent, and therefore, the application range of the lamp is limited in the application occasions with special requirements. Meanwhile, the exhaust tube of the lamp tube protrudes out of the lamp tube, and the exhaust tube can be discarded once being broken and damaged, so that the position of the exhaust tube needs to be noticed when the lamp tube is used, and the application range of the lamp is further limited.

Detailed Description
The features, nature, and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings and embodiments.
Fig. 2A and 2B are block diagrams of an embodiment according to the present invention, and fig. 2A and 2B are views in two different directions, respectively. As shown in fig. 2, the electromagnetic induction lamp 200 of this embodiment includes the following structure:
a base 202, the base 202 being mountable to a lamp holder. The lamp base 202 has the same structure as a lamp base of a conventional art, and the lamp socket has the same structure. The control circuit shell 204 is connected to the lamp head 202, the lamp head 202 is sleeved on the control circuit shell 204, and the control circuit 206 is arranged in the control circuit shell 204. A lamp tube 208 having an inner wall coated with a phosphor layer, the lamp tube having a chamber containing a gas and an amalgam (as described in more detail in connection with the description of fig. 3). And the magnetic ring hoop 210 is sleeved on the lamp tube 208 and surrounds a certain section of the lamp tube 208. Within the magnetic ring hoop 210 is a magnetic ring 212, the magnetic ring 212 also surrounding the above-mentioned cross section of the lamp tube 208. Referring to the embodiment shown in fig. 2, the shape of the lamp vessel is "U" here, with a bridge in the opening of the "U" (as will be described in more detail later in connection with fig. 3). The magnetic ring hoop 210 is located at the bridge, surrounding a cross section of the bridge. A coil 214 is wound around the magnetic ring 212, and the coil 214 is connected to the control circuit 206 to provide a magnetic field to ignite the electromagnetic induction lamp 200. According to the technical scheme of the invention, only one magnetic ring hoop 210 is adopted, and as shown in fig. 2, when the U-shaped lamp tube with the bridge connection is adopted, the position of the magnetic ring hoop 210 is positioned in the hollow crotch in the middle of the lamp tube, so that extra space is not required to be occupied, and the whole volume of the lamp tube can be reduced. The present embodiment further comprises a clamping plate 216, such that the lamp tube 208 and the magnetic ring hoop 210 are not directly connected to the control circuit housing 204, but are connected to the clamping plate 216, and the clamping plate 216 is connected to the control circuit housing 204. Fig. 2B is a sectional view of a portion of the lamp tube 208 and the connection between the magnetic ring hoop 210 and the clamp plate 216, which is made by screws in this embodiment.
Fig. 3A and 3B are structural views of a lamp tube of one embodiment of the present invention, again from two directions. As shown in fig. 3, the lamp 300 in this embodiment is shaped as a "U" shaped lamp, and a bridge 302 is disposed in the "U" shaped opening, and the magnetic ring hoop 210 in this embodiment is sleeved on the bridge 302. It should be noted that the present invention is not limited to the shape of the lamp tube, any shape of the lamp tube that can form a closed shape can be used, and the position of the magnetic ring hoop 210 is not fixed, as long as it can surround a certain section of the lamp tube. It is easy to think that when the lamp tube is redesigned, the lamp tube is provided with a relatively thin part, which is beneficial to installing a small magnetic ring hoop, so that the whole volume of the lamp can be reduced. The shape of the tube shown is a preferred choice but is not intended to limit the scope of the invention to the shape disclosed herein. The invention also provides an improvement on the lamp tube, namely, the exhaust tube is arranged inside the lamp tube. As shown in FIG. 3, at one end of the "U" shape, there is a concave portion, namely the exhaust tube 304. compared with the prior art (refer to FIG. 1), the exhaust tube 304 in the lamp of the present invention no longer protrudes out of the lamp, so that the possibility of damaging the exhaust tube of the lamp is greatly reduced. Meanwhile, in the exhaust pipe 304, besides the solid mercury 306, an indium net 308 is added, the indium net 308 can reduce the influence of the outside temperature on the starting and the working of the lamp, and the lamp can reach the rated luminous flux and the full power state instantly after being started. To improve the operation of the lamp, one or more ports for placing indium mesh 308 may be provided in the lamp tube, for example, in this embodiment, the other end 310 of the "U" tube is provided with a port for placing indium mesh 308. The inner wall of the lamp vessel 300 is coated with a phosphor layer 312 and the chamber of the lamp vessel contains a gas and an amalgam 314, as in the prior art lamp vessel. Fig. 3B illustrates the structure of the lamp 300 from the side, and the connection with the magnetic ring hoop 210 has been described previously and will not be repeated here.
After the technical scheme of the invention is adopted, the exhaust pipe of the lamp tube is transferred from the original outside of the lamp tube to the inside of the lamp tube, so that the problem of exhaust pipe breakage caused by improper operation and transportation in the production process is fundamentally solved, the consumption in the production process is reduced, and the production cost is reduced. Meanwhile, the difficult problem of avoiding the exhaust pipe is not considered in the design of the lamp. The starting and the working of the lamp are slightly influenced by the external temperature, and meanwhile, the electromagnetic induction lamp only uses one magnetic ring, and compared with the traditional electromagnetic induction lamp, the electromagnetic induction lamp can be applied to various narrow and small occasions, so that the electromagnetic induction lamp really moves towards miniaturization and replaces the existing energy-saving lamp. The indium net is used as an auxiliary starting, so that the lamp can reach rated luminous flux instantly after being started.
The embodiments described above are provided to enable persons skilled in the art to make or use the invention and that modifications or variations can be made to the embodiments described above by persons skilled in the art without departing from the inventive concept of the present invention, so that the scope of protection of the present invention is not limited by the embodiments described above but should be accorded the widest scope consistent with the innovative features set forth in the claims.
