Description
Technical field
The utility model relates to a kind of led light source module.Especially a kind of led light source module that possesses waterproof and heat dispersion that is used for the open air.
Background technology
Existing led lamp had both had the light and handy of conventional lamp, can save plurality of advantages such as a large amount of energy again, therefore was widely used in stereo luminous character, advertising lamp box, signboard, sign and decorative lamp etc. and used as light source.And along with to the improving constantly of brightness requirement, the method that solves is to increase the drive current of light-emitting diode and increase LED core area etc. at present.Consequent problem is, along with the sharp increase of current density can make light-emitting diode heating phenomenal growth.At above problem, patent 02248875.8 discloses a kind of power-type LED based on metal circuit board, is provided with metallic radiating layer in the wiring board bottom, to solve owing to current density increases the heating problem that causes.
But because the assembling mode of light-emitting diode is modularization and the installation and connection method that adopts as shown in Figure 1 more, the electric current wiring board that each is connected of need flowing through, from having influenced the caloric value and the quality of light-emitting diode (LED) module wiring board, and, one of them of the wiring board of numerous series connection will cause the inefficacy of whole light-emitting diode (LED) module group when occurring burning or open circuit.In addition, in order to adapt to the outdoor open-air needs of showing, protection against the tide, anticorrosion, waterproof, anti-aging, the requirement of dispelling the heat have been proposed light-emitting diode (LED) module.
Summary of the invention
The purpose of this utility model is to provide a kind of waterproof cooling type led light source module, adopts new connection mode, with the heating problem of solution wiring board, and has guaranteed that local module inefficacy can not exert an influence to whole module group.
The utility model is to realize above-mentioned purpose like this:
Waterproof cooling type led light source module, comprise the metal shell of groove shaped and be installed on the bar shaped wiring board of forming by printed circuit, insulating barrier and metal heat-conducting layer in the metal shell, be welded with light-emitting diode, resistance and power supply input heart yearn, power supply output heart yearn on the bar shaped wiring board, wiring board by the casting glue encapsulation in the enclosure.Described power supply input heart yearn, power supply output heart yearn stretch out from long limit, the both sides of bar shaped wiring board, and its both positive and negative polarity leg correspondence is connected on the same cross-sectional between the two long limits of bar shaped wiring board, is electrically connected between the two.
In addition, in order to satisfy multiple requirement such as outdoor water-proof sunshade, casting glue adopts uvioresistant tape heat radiating type electron pouring sealant.
The beneficial effects of the utility model are: have the wiring board of metal heat-conducting layer and the heat dissipation problem that metal shell can solve LED light-source module effectively on the one hand, on the other hand owing to adopt new power supply line design, the wiring board of each module is only by the rated current for light-emitting diode work in this module, the trunk supply current of all modules only conducts by power line, therefore can effectively reduce the caloric value of wiring board in each module, avoid again because the disparate modules brightness disproportionation that the pressure drop that wiring board causes causes and guarantee that local module inefficacy can not exert an influence to whole module group; Also adopted antiultraviolet heat radiating type casting glue, made the led light source module have good protection against the tide, anticorrosion, waterproof, anti-aging, heat dissipation characteristics satisfy the outdoor open-air harsh requirement of showing fully.
