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.
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. The utility model discloses an improve the quantity that the point lies in magnetic ring staple bolt 210 promptly, according to the utility model discloses a technical scheme, it only adopts a magnetic ring staple bolt 210, and as shown in fig. 2, when adopting this kind of "U" type fluorescent tube that has the bridging, this magnetic ring staple bolt 210's position is in the empty crotch in the middle of the fluorescent tube, does not need additionally occupation space, consequently can reduce the whole volume of fluorescent tube. 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 according to an embodiment of the present invention, also 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 does not limit the shape of the lamp tube, any lamp tube shape 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 meant to limit the scope of the invention to the shape disclosed herein. For the lamp tube, the utility model discloses also there is an improvement, just place the inside of lamp tube with the blast pipe. As shown in fig. 3, there is a concave portion at one end of the U-shape, which is the exhaust pipe 304. compared with the prior art (refer to fig. 1), the exhaust pipe 304 in the lamp tube of the present invention no longer protrudes out of the lamp tube, so that the possibility of damaging the exhaust pipe of the lamp tube 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.
Adopt the technical scheme of the utility model afterwards, with the blast pipe of fluorescent tube outside the original fluorescent tube shift take the fluorescent tube inside, fundamentally solves in the production process, because the operation and the transport improper and the broken problem of blast pipe that causes reduce the consumption in the production process, reduction in production cost. 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 above-described embodiments are provided to enable persons skilled in the art to make or use the invention, and many modifications and variations may be made to the above-described embodiments by persons skilled in the art without departing from the inventive concept of the present invention, so that the scope of the invention is not limited by the above-described embodiments, but should be accorded the widest scope consistent with the innovative features set forth in the claims.
