Abstract

The utility model relates to LED luminaire, comprising an LED luminophor, a shell, as well as a heat conduction column and a circuit board which are formed into a whole part, one part of which is in the inside of the shell and the other part is in the outside of the shell. The circuit board is fixed in the shell and is provided with a plurality of holes, the diameters of which are larger than that of the heat conduction column, thus to make the circuit board be sleeved on the heat conduction column in the shell and is fixed on the circuit board, and heat conduction lipids are distributed between the LED luminophor and the heat conduction column. The utility model has the advantages of short thermal channel, less thermal resistance and good radiating effect.

Description

A kind of LED light fixture

Technical field

The utility model belongs to lighting field, particularly relates to a kind of LED light fixture that dispels the heat good.

Background technology

At present, the LED that uses in the known high-capacity LED light fixture has two kinds, the band aluminium base and not with aluminium base, a kind of mounting means be will the band aluminium base LED be directly installed on the shell its passage of heat is the copper post among the LED--thermal grease conduction--aluminium base--thermal grease conduction--shell.Another kind of mounting means is not to be welded on the big compound aluminium base with the LED of aluminium base is integrated, and then this piece composite aluminum substrate is fixed on the shell its passage of heat also is the copper post among the LED--thermal grease conduction--composite aluminum substrate--thermal grease conduction--shell.The general character of these two kinds of radiator structures is that the passage of heat is long, and between each coupling part thermal resistance is arranged all, thereby radiating effect is not good.

Summary of the invention

To be solved in the utility model is the bad problem of high-power LED lamp heat radiation, and a kind of LED light fixture that dispels the heat good is provided.

For this reason, the utility model has adopted following technical scheme: the LED light fixture comprises LED illuminator and shell, it is characterized in that, it also comprises heating column and wiring board, and heating column and shell are integrally formed, its part inside the shell and another part in the shell outside; Wiring board is fixing inside the shell, and has the hole of several diameters greater than the heating column diameter, thereby makes it can be enclosed within on the heating column; The LED illuminator is located on the heating column of shell inboard, fixes with wiring board, also is distributed with thermal grease conduction between LED illuminator and heating column.

Further, heating column inside the shell the part height less than 2mm.

Further, described heating column is hollow, and inside is threaded, and described LED illuminator lower end also is threaded, and is connected with heating column by threaded engagement.

The utility model does not adopt aluminium base, and its passage of heat is copper post--thermal grease conduction--heating column (being shell) of LED, and such passage of heat has reduced the thermal resistance of two connecting links than the known passage of heat, can improve radiating effect effectively; The LED illuminator is threaded with heating column, has then further increased both contacts area, has improved heat conduction efficiency.

Description of drawings

Fig. 1 is the schematic diagram of an embodiment of the utility model.

Fig. 2 is the schematic diagram of another embodiment.

The specific embodiment

Referring to Fig. 1.In the present embodiment, 5 is shell, and 2 is the LED illuminator, is located at the shell inboard; Heating column 4 is integrally formed with shell 5, and wiring board 1 is fixed on the inboard of shell 5, thereby and be provided with several holes and be enclosed within on the heating column 4; LED illuminator 2 is fixed on the wiring board 1, and fills the space with thermal grease conduction 3.

Referring to Fig. 2.Present embodiment and embodiment one basically identical, difference are heating column 4 for hollow, and inside is threaded, and LED illuminator 2 lower ends also are threaded, and both are connected by threaded engagement.

Claims

1.LED light fixture comprises LED illuminator and shell, it is characterized in that, it also comprises heating column and wiring board, and heating column and shell are integrally formed, its part inside the shell and another part in the shell outside; Wiring board is fixing inside the shell, and has the hole of several diameters greater than the heating column diameter, thereby makes it can be enclosed within on the heating column; The LED illuminator is located on the heating column of shell inboard, fixes with wiring board, also is distributed with thermal grease conduction between LED illuminator and heating column.
