Abstract
The illumination ornament includes the backbone circuit, the branch circuits connected to the backbone circuit, the lamps installed on the branch circuits and the illumination circuit. The self-recovery type safety device is installed in the backbone circuit and the branch circuits. The self-recovery type safety device is the self-recovery type fuse being as the PPTC polymer or bimetal strip. When over loading or short circuit being happened in the circuits, the self-recovery type fuse presents high impedance to block out the circuits. The self-recovery type fuse can recover back to on state. Thus, once being installed, the self-recovery type fuse can be used repeatedly.
Description
Technical field
The present invention relates to a kind of lamp decoration, is the improvement technology of lamp decoration safety protective circuit specifically.
Background technology
At present; the safety protective circuit of people in the lamp decoration industry adopts disposable fuse as overflow protecting element mostly, and such as low-melting metal tin bar, but this disposable fuse needs timely replacing after fusing; therefore, use bother very much and operate dangerous.Decorative lamp is because of the needs of result of use in the lamp decoration industry, frequent serial or parallel connection multichannel bulb, and bulb presents various variation in use, and like this, lamp decoration is had higher requirement aspect safety protective circuit.
The purpose of this invention is to provide good, the easy to use lamp decoration of a kind of security protection.
The present invention is achieved through the following technical solutions the object of the invention.
A kind of lamp decoration with safety protective circuit comprises trunk roads, and the branch road that links to each other with trunk roads and be installed in lamp on the branch road is characterized in that: the self-resetting type safeties are installed on the circuit of described lamp decoration.
Described self-resetting type safeties are installed on the trunk roads of lamp decoration circuit.
Described self-resetting type safeties are installed on the branch road of lamp decoration circuit.
Described self-resetting type safeties are self-healing fuse.
Described self-healing fuse is a PPTC polymer self-healing fuse.
Described self-resetting type safeties are the bimetallic shell fragment.
Described lamp decoration be Christmas lights or red-letter day celebrating lamp decoration.
The present invention compared with prior art has the following advantages.
On the circuit of lamp decoration self-healing fuse is installed, when overload or short circuit took place circuit, self-healing fuse presented high impedance, blocking circuit, and the protection load, after fault is got rid of, but self-healing fuse returns to "on" position voluntarily.So self-healing fuse can once mounting, use very easy to use, safety repeatedly.
Description of drawings
Fig. 1 for self-healing fuse of the present invention be installed in one the tunnel series connection bulb trunk roads on structural representation;
Fig. 2 is installed in structural representation on the trunk roads of multichannel connection in series-parallel bulb for self-healing fuse of the present invention;
Fig. 3 is installed in by the structural representation on the trunk roads of IC control multichannel connection in series-parallel bulb for self-healing fuse of the present invention;
Fig. 4 is installed in structural representation on the branch road of multichannel connection in series-parallel bulb for self-healing fuse of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Self-resetting type safeties among the present invention adopt self-healing fuse or bimetallic shell fragment or other to have the parts of identical function, Fig. 1, Fig. 2 and Fig. 3 are installed in three kinds of embodiment on the trunk roads of lamp decoration for the self-healing fuse a among the present invention, certainly, self-healing fuse a can also be installed on each branch road of lamp decoration.Self-healing fuse a among the present invention adopts PPTC polymer self-healing fuse, PPTC polymer self-healing fuse is made up of macromolecular material and electrically conductive particles, its operation principle is as follows: under the normal condition, electrically conductive particles constitutes the chain conductive channel in macromolecular material, element maintains low impedance state.When circuit in overload or during short circuit, the heat that big electric current produces expands macromolecular material rapidly, cuts off the chain conductive channel, element is a high impedance by the Low ESR transition, blocking circuit, protection load.After fault was got rid of, the macromolecular material cooling was shunk automatically, and conductive channel links again, and element returns to initial condition again voluntarily, thereby realized the purpose of " reuse, need not change, put things right once and for all ".
