Summary of the invention
The technical problem to be solved in the present invention is to provide the LED lamp holder with self-protection function that a kind of protected effect is good, easy to use, long service life, structure are simple, with low cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of LED lamp holder with self-protection function; comprise the bulb socket with connecting thread; described bulb socket is provided with circuit board; the bottom of described bulb socket is provided with lampshade; the inner side of lampshade is located at by described circuit board; described circuit board is provided with contact electrode, LED unit and bimetal release; described LED unit by bimetal release with contact electrode be connected; described bimetal release is made up of the electrode contacted with each other and bimetal leaf, and described bimetal leaf is formed by the two panels metal composite that thermal coefficient of expansion is different.
Further improvement as technique scheme:
Described LED unit comprises the first LED group, the second LED group, described first LED group, the second LED group include at least one LED, each LED of described first LED group respectively with contact electrode and be connected, each LED of described, the second LED group respectively by bimetal release with contact electrode and be connected.
Described bulb socket is provided with installing hole, and the upside of described circuit board is provided with holder, and described holder plugs and is fixed in installing hole, and described LED unit is located at the downside of circuit board, and described contact electrode, bimetal release are located on the end face of holder.
The present invention has following advantage: the present invention controls the duty of LED unit by bimetal release; thus the self-protection function realized LED lamp holder; when LED unit operating ambient temperature comparatively Gao Shihui cause bimetal release to be subject to thermal cutoff; thus the power supply of some or all of LED in switching LED unit; once after temperature return; then bimetal release recovers automatically; whole LED of LED unit are restored electricity, there is the advantage that protected effect is good, easy to use, long service life, structure are simple, with low cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the partial enlargement sectional structure schematic diagram of Fig. 1.
Marginal data: 1, bulb socket; 10, connecting thread; 11, installing hole; 2, circuit board; 20, holder; 21, electrode is contacted; 22, LED unit; 221, the first LED group; 222, the second LED group; 23, bimetal release; 3, lampshade.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As depicted in figs. 1 and 2; the LED lamp holder that the present embodiment has a self-protection function comprises the bulb socket 1 with connecting thread 10; bulb socket 1 is provided with circuit board 2; the bottom of bulb socket 1 is provided with lampshade 3; the inner side of lampshade 3 is located at by circuit board 2; circuit board 2 is provided with contact electrode 21, LED unit 22 and bimetal release 23, LED unit 22 by bimetal release 23 with contact electrode 21 connected.The present embodiment controls the duty of LED unit 22 by bimetal release 23, bimetal release 23 is made up of the electrode contacted with each other and bimetal leaf, bimetal leaf is formed by the two panels metal composite that thermal coefficient of expansion is different, when bimetal leaf continues to be heated, can disconnect with electrode, when bimetal leaf is not heated, can slowly return to and electrode contact, thus the self-protection function to LED lamp holder can be realized by bimetal release 23, when LED unit 22 operating ambient temperature comparatively Gao Shihui cause bimetal release 23 by thermal cutoff, thus switch the power supply of some or all of LED in LED unit 22, once after temperature return, then bimetal release 23 recovers automatically, whole LED of LED unit 22 are restored electricity, there is protected effect good, easy to use, long service life, structure is simple, advantage with low cost.
In the present embodiment, LED unit 22 comprises the first LED group 221, second LED group 222, first LED group 221, second LED group 222 includes at least one LED, each LED of first LED group 221 respectively with contact electrode 21 and be connected, , each LED of second LED group 222 respectively by bimetal release 23 with contact electrode 21 and be connected, therefore once the heat on circuit board 2 causes bimetal release 23 to bend, then bimetal release 23 can disconnect the power supply of the second LED group 222 automatically, second LED group 222 is extinguished, only retain the first LED group 221 in running order, by reducing in running order LED quantity, prevent circuit board 2 from continuing heating.
In the present embodiment; bulb socket 1 is provided with installing hole 11; the upside of circuit board 2 is provided with holder 20; holder 20 plugs and is fixed in installing hole 11, and LED unit 22 is located at the downside of circuit board 2, and contact electrode 21, bimetal release 23 are located on the end face of holder 20; syndeton between bulb socket 1, circuit board 2 is simple; and the end face of holder 20 is located at by bimetal release 23, better to the susceptibility of heat, thus protected effect is better.
The foregoing is only the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme belonging to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, some improvements and modifications of carrying out under the prerequisite not departing from principle of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
