Detailed description of the invention
Embodiment 1, as it is shown in figure 1, the present embodiment is a kind of double end ceramic gold-halogen lamp, it is the ceramic gold-halogen lamp being provided with two ceramic arc tubes in a vacuum fluorescent tube.
As shown in Figure 1, in a vacuum fluorescent tube 3, first ceramic arc tube 1 and the second ceramic arc tube 2 are connected in series in, second electrode 102 of the first ceramic arc tube 1 is connected with the first electrode 201 of the second ceramic arc tube 2, first electrode 101 of the first ceramic arc tube 1 and the second electrode 202 of the second ceramic arc tube 2 are respectively adopted extension lead 10 and stretch out from the two ends of vacuum fluorescent tube 3, utilize in the place stretched out potsherd 9 fixing and be connected with the hard wire drawn outward, so, the bayonet socket arranging a fixed light herein just can install lamp.
nullDue in vacuum fluorescent tube 3，Owing in the case of ceramic gold-halogen lamp in use bright light itself and non-bright light, variations in temperature is bigger，Electrode and extension lead 10 is utilized to be supported in vacuum fluorescent tube 3 by two ceramic arc tubes，Also need to utilize some bracing frames 4 to support fixing in different places for two ceramic arc tubes stringed together by electrode and extension lead 10，As shown in the figure，The present embodiment have employed three bracing frames 4，Wherein，In the middle of two ceramic arc tubes，Namely the second electrode 102 of the first ceramic arc tube 1 and the first electrode 201 junction of the second ceramic arc tube 2 arrange a bracing frame 4，A bracing frame 4 substantially circle，The center of circle of circle is exactly the second electrode 102 and first electrode 201 junction of the second ceramic arc tube 2 of the first ceramic arc tube 1，Use that to be fixed several support bars by the center of circle along circle radius direction to circled the most permissible，Owing in vacuum fluorescent tube 3, temperature is the highest，Need again stronger intensity，Therefore，Metal rack can be used，Because the tube wall as vacuum fluorescent tube 3 typically uses glass，Insulating properties are preferable，Therefore，Metal rack is fixing with electrode without doing Insulation Scheme，Certainly，In practice，We still have one layer of preferable ceramic layer of insulating properties outside electrode.It addition, two bracing frames 4 are separately positioned on the both sides of ceramic arc tube, shape is consistent with this.
On electrode and extension lead 10, being additionally provided with inspiration piece 6, inspiration piece 6 is the foreign gas in absorbing vacuum fluorescent tube 3, improves the vacuum in vacuum fluorescent tube 3.Expand with heat and contract with cold it addition, be additionally provided with connection hook 7 on extension lead 10 with correspondence.In order in order to be effective, one group of inspiration piece 6 can be respectively set in the both sides of ceramic arc tube and connect hook 7.
In the present embodiment, explosion stack 8 can also be set outside vacuum fluorescent tube 5, as fixing ceramic arc tube in vacuum fluorescent tube 3, in the present embodiment, use several ring for fixing 5 to be fixed on outside vacuum fluorescent tube 3 by explosion stack 8.
Embodiment 2, there is from embodiment one two and be respectively arranged with unlike an electrode output, the present embodiment only utilizes a lamp holder 12, a fixed support 11 can be arranged in whole explosion stack 8 be fixed in explosion stack 8 by the ceramic arc tube of vacuum fluorescent tube 3 and two series windings of inside, and the electrode stretched out at two ends by wire between support received one end and forms single head lamp holder 12, as shown in Figure 2.
