Abstract
A safety protection device of LED decoration lamp is provided, which comprises a shell, a surge absorber, a bridge rectifier and a thermostatic switch. The surge absorber and the thermostatic switch are fixed on a cooling plate in the shell, and the bridge rectifier and the surge absorber are connected with an AC circuit in parallel. The live wire passed through the surge absorber goes up to connect the thermostatic switch, and the thermostatic switch and the bridge rectifier are fixed on the cooling plate. Then a kind of insulated glue with good thermal diffusivity is used to fill the shell. The utility model has simple structure, good waterproof and heat dispersion performance; moreover, it is convenient to mount and maintain, which effectively prevents the damage of the luminescent lamp due to sudden increase of the voltage or current.
Description
Affiliated technical field
The utility model relates to a kind of LED ornament lamp, especially a kind of safety guard of LED ornament lamp.
Background technology
The lamp body structure that general application is formed with light emitting diode (LED), because present civil power is 110V or 220V voltage, therefore need be direct current with its step-down and rectification just through transformer, can supply light emitting diode (LED) luminous, traditional way is to connect controller, do not have like this under the situation of specific (special) requirements, just caused the increase of lamp body cost, wasted material yet.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, come simplified structure to reduce cost like this, but one of them light emitting diode of this product (LED) is damaged when not working, so that cause other good light emitting diode when voltage that is suddenlyd change or electric current, also connect thereupon and involve damage, so, very unfavorable for whole lamp body, and this kind structure is not easy to maintenance.
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, safety guard that be easy to produce and assemble, be convenient to keep in repair, can effectively prevent from the to suddenly change voltage that strengthens or electric current damage a kind of LED ornament lamp of whole lamp.
For achieving the above object; the technical solution adopted in the utility model is: a kind of safety guard of LED ornament lamp; it comprises housing, surge absorber (5), bridge rectifier (3); it is characterized in that: in housing; bridge rectifier (3) and surge absorber (5) are connected in the alternating current circuit; through jointing temp gauge tap (6) on the live wire behind the surge absorber (5), temp control switch (6) and bridge rectifier (3) are fixed on the heat sink (4).
Space in the described housing is filled up with glue, with all electrical equipment parcels; Described housing is that loam cake (7) and lower base (2) two parts are formed; Groove and the convex tendon that matches arranged on the abutted surface of described loam cake (7) and lower base (2).
The utility model is compared its beneficial effect with present technology to be had: the utility model adopts the way of placing surge absorber, bridge rectifier and temp control switch in the housing, effectively prevents to damage illuminator because of voltage or electric current increase suddenly.When connecing load surpassed current limit, temp control switch meeting automatic disconnection was to remind the user.With the electrical equipment 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, and is simple in structure, is 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;
The specific 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 safety guard of LED ornament lamp; it comprises housing; surge absorber (5); bridge rectifier (3); temp control switch (6); surge absorber (5) and temp control switch (6) are fixed on the interior heat sink of housing; bridge rectifier (3) and surge absorber (5) are connected in the alternating current circuit; through jointing temp gauge tap (6) on the live wire behind the surge absorber (5); with nut (8) be with externally threaded power line protection joint (1) that power line is fixed; 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 (7) 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.
