Abstract
An LED (Light Emitting Diode) lamp comprises a metal shell and has the following key points: an insulation circuit board with a through hole is arranged on the inner surface of the metal shell, a pin of the LED lamp is welded on the circuit board, and the through hole is internally provided with a heat conduction post which is tightly attached on the metal shell and a radiating piece of the LED lamp. In the LED lamp, an aluminum plate is not needed for heat radiation, so that the cost is lowered; and simultaneously, the heat on the heat radiating piece of the LED can be directly transferred to the metal shell along a metal conductor, so that the heat radiation effect is strengthened.
Description
Technical field
The utility model relates to a kind of lighting, relates in particular to the lamp interior mounting structure.
Background technology
At present, because LED lamp long service life, advantages such as power saving have obtained being widely used.The LED lamp is made up of the chip part at top bulb, middle part and the fin of bottom.The LED lamp is in when illumination, and chip section branch produces bigger heat, if untimely distributing can be shortened service life of LED lamp.Usually the LED light fixture comprises metal shell and aluminium base copper-clad plate, and the copper layer forms the conducting wire, and the pin welding of LED lamp in the circuit board.The fin of LED is close on the insulating barrier, and heat passes to metal shell through insulating barrier through the aluminium sheet in the aluminium base copper-clad plate and dispels the heat.But this structure needs more aluminium sheet, has increased production cost, when producing, can not guarantee that the bottom aluminium sheet contacts with shell fully, causes radiating effect undesirable simultaneously.
The utility model content
The purpose of the utility model is a kind of LED light fixture of good heat dissipation.
To achieve these goals, adopt following technical scheme:
A kind of LED light fixture; Comprise metal shell; It is characterized in that: said metal shell inner surface is provided with the insulating circuit board with through hole, and the pin of LED lamp is welded on the circuit board, is provided with the heating column that the fin with metal shell and LED lamp fits tightly in the said through hole.
Assembling for ease, said heating column and metal shell are integrated.
The utility model does not need aluminium sheet to dispel the heat, and has reduced cost, and the heat on the fin of LED can be directly passed to metal shell along metallic conductor simultaneously, has strengthened the effect of heat radiation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of A among Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done and to be further described:
Embodiment 1: as depicted in figs. 1 and 2; A kind of LED light fixture; Comprise metal shell 1; Metal shell 1 inner surface is provided with the insulating circuit board 3 with through hole, and the pin of LED lamp is welded on the circuit board 3, is provided with the heating column 4 that the fin with metal shell 1 and LED lamp 2 fits tightly in the said through hole.
Embodiment 2: different with embodiment 1 is, heating column 4 is integrated with metal shell 1, and such structure is convenient installs, and directly insulating circuit board is buckled in the metal shell inner surface and gets final product, and need not the independent installation heating column.
Above insulating circuit board can be epoxy resin fiberglass cloth copper-clad plate, cardboard copper-clad plate or other insulating circuit board.
More than show and described the advantage of basic principle, major technique characteristic and the utility model of the utility model.The utility model is not restricted to the described embodiments, the principle of describing in the foregoing description and the specification that the utility model just is described., all belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
Claims (2)
1. LED light fixture; Comprise metal shell; It is characterized in that: said metal shell inner surface is provided with the insulating circuit board with through hole, and the pin of LED lamp is welded on the circuit board, is provided with the heating column that the fin with metal shell and LED lamp fits tightly in the said through hole.
2. LED light fixture as claimed in claim 1 is characterized in that: said heating column and metal shell are integrated.
