Abstract
A simple protector for LED decorative light is provided, which comprises a shell, a bridge rectifier, and a temperature control switch. The temperature control switch is connected with a live wire in the shell. And then, the bridge rectifier is connected with an AC circuit in parallel. The bridge rectifier and the temperature control switch are arranged on a cooling plate of the shell. A protective power lead connector with nuts and external threads is utilized to fix the power lead. Other internal shell space is filled with a type of glue characterized by excellent insulation and heat radiating performance. The utility model has advantages of simple structure, excellent waterproof and radiating performance, great convenience in assembling and maintenance and effective prevention against light damage due to sudden voltage or current boost.
Description
Affiliated technical field
The utility model relates to a kind of LED decorative lamp, especially a kind of simple protective device of LED decorative lamp.
Background technology
Because light-emitting diode (LED) has reliably, low power consuming, hang down superior functions such as working temperature and long life, the LED decorative lamp is more and more universal in people's life.LED lamp decoration manufacturer when maximization improves the brightness of LED lamp and other advantage, the gap between the production cost that dwindles LED lamp decoration and conventional incandescent of always trying every means.As everyone knows, the LED lamp is only worked under DC power supply can give play to high brightness and long-life advantage, and most of ways all are to connect one " bridge heap " according to the bridge rectifier principle or be called " silicon bridge " to realize the AC-DC conversion with this in circuit.When voltage or current break increasing, can make " bridge heap " to produce a large amount of heat rapidly, and then " bridge heap " burnt, LED is thereafter damaged.Because " bridge heap " can produce certain heat when realizing the AC-DC conversion work, if do not take effective radiating mode, its accumulation of heat also can damage " bridge heap ".The product of the patent No. 02239271.8, a kind of LED lamp string with AC-DC conventer, this product utilization bridge rectifier principle, 4 diodes and 2 pcb boards are combined, it is one-piece type to be injected into sealing, but this structure is when power is big, and caloric value is quite big, and there is not good radiating mode, very dangerous.
Summary of the invention
For solving the problem of above-mentioned existence, the utility model purpose is to provide a kind of simple in structure, perfect heat-dissipating, can control temperature too high, be easy to produce and assemble, be convenient to keep in repair, can effectively prevent to suddenly change the voltage that strengthens or electric current and damage the simple protective device of a kind of LED decorative lamp of lamp body.
For achieving the above object; the technical solution adopted in the utility model is: a kind of simple protective device of LED decorative lamp; it comprises housing, bridge rectifier (3); it is characterized in that: in housing; be connected to temp control switch (5) on the live wire; bridge rectifier (3) is connected in the alternating current circuit, and temp control switch (5) is connected to bridge rectifier (3) before.
Described temp control switch (5) and bridge rectifier (3) are fixed on the heating panel (4); Space in the described housing is filled up with glue, with all electric component parcels; Described housing is that loam cake (6) and lower base (2) two parts are formed; Groove and the convex tendon that matches arranged on the abutted surface of described loam cake (6) and lower base (2); The nut (7) and the corresponding housing through-hole that external screw thread are arranged and match on the protection joint (1) of the power line of described circuit and housing joint with external screw thread.
The utility model is compared its beneficial effect with present technology to be had: the way of jointing temp control switch and bridge rectifier in the circuit in the utility model employing housing, when voltage or electric current excessive, when temperature is elevated to a limit that is unfavorable for work in the housing, temp control switch is turn-off current immediately, with the electric component in the glue parcel housing, strengthened water resistance and can effectively dispel the heat, housing is divided into loam cake and lower base two parts, simple in structure, be convenient to assembling and maintenance.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the utility model embodiment;
Fig. 2 is the present embodiment electrical schematic diagram;
Embodiment
Below in conjunction with accompanying drawing utility model is described further:
With reference to Fig. 1; Fig. 2; the utility model embodiment: a kind of simple protective device of LED decorative lamp; it comprises housing; bridge rectifier (3); temp control switch (5); in the circuit in housing; jointing temp control switch (5) on the live wire; then bridge rectifier (3) is connected in the alternating current circuit; temp control switch (5) is connected to bridge rectifier (3) before; temp control switch (5) and bridge rectifier (3) are fixed on the interior heating panel (4) of housing; pass the through hole of housing fixes power line with nut (8) with externally threaded power line protection joint (1); with a kind of insulation and the good glue of heat dispersion the space in the housing is filled up then; element parcel with all in the housing fixes loam cake (6) and lower base (2) with screw.
Above institute only gives an actual example with convenient explanation the utility model, is not breaking away from creation spirit category of the present utility model, person skilled in the art scholar did various simple and easy covert with modify, still be included in the technical solution of the utility model scope.
