Description

LED module of blind area lamp

Technical Field

The utility model relates to a car light device field especially relates to blind area lamp LED module.

Background

The car light is a lamp on a vehicle, is a tool for illuminating the road when the vehicle runs at night, and is also a prompting tool for sending various vehicle running signals; the following problems exist in the use process of the blind area lamp at present:

firstly, LED lamp pearl and drive module's components and parts are installed in one side, and LED lamp pearl is on components and parts are conducted easily to the heat that produces in the use, shortens the life of components and parts greatly.

Secondly, the heat dissipation structure is relatively simple, and the heat dissipation effect is not good.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a good and long service life's of radiating effect blind area lamp LED module.

The technical scheme of the utility model as follows:

the blind area lamp LED module comprises a circuit board assembly, a supporting assembly and a heat dissipation assembly; the supporting assembly comprises hollow supporting bars, a plurality of grooves are uniformly distributed on the supporting bars, and the supporting bars between every two grooves form a convex part; mounting columns with jacks are arranged on the grooves and the convex parts; the circuit board assembly comprises a flexible PCB, a plurality of mounting holes matched with the mounting columns for use are formed in the flexible PCB, and LED lamp beads are arranged on the flexible PCB on one side of each mounting hole.

The heat dissipation assembly comprises a heat conduction column arranged in the protruding portion and the groove, the heat conduction end of the heat conduction column penetrates through the supporting bar and is in contact with the flexible PCB, and the other end of the heat conduction column is connected with the plurality of heat dissipation fins.

And a heat-conducting insulating silica gel sheet is arranged between the heat-conducting column and the flexible PCB.

The heat conducting end is disc-shaped.

The radiating fins are distributed in a circular shape by taking the central line of the heat conducting column as the center of a circle.

The flexible PCB board is connected with the power panel through a wire.

The power panel is located the support bar bottom.

The utility model has the advantages that: because the supporting bar is step-shaped and adopts the flexible circuit board, the whole lamp body has more layering sense and more beautiful appearance after the lamp is lighted; the mounting posts are distributed more uniformly, and the flexible circuit board is fixed by the mounting posts, so that the circuit board is more firmly mounted.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Wherein: FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the structure of the heat dissipation fin of the present invention;

in the attached drawing, 1 is the circuit board subassembly, 2 is supporting component, 3 is radiator unit, 4 is the support bar, 5 is the recess, 6 is the bellying, 7 is the erection column, 8 is flexible PCB board, 9 is LED lamp pearl, 10 is the heat conduction post, 11 is radiating fin, 12 is heat conduction insulating silica gel piece, 13 is the wire, 14 is the power strip.

Detailed Description

Referring to fig. 1-2, the blind zone lamp LED module includes a circuit board assembly 1, a support assembly 2 and a heat dissipation assembly 3; the supporting component comprises a hollow supporting strip 4, a plurality of grooves 5 are uniformly distributed on the supporting strip, and a convex part 6 is formed by the supporting strip between every two grooves; the groove and the bulge are both provided with mounting columns 7 with jacks; the circuit board assembly comprises a flexible PCB (printed circuit board) 8, a plurality of mounting holes matched with the mounting columns for use are formed in the flexible PCB, and LED lamp beads 9 are arranged on the flexible PCB on one side of each mounting hole. Because the supporting bar is step-shaped and adopts the flexible circuit board, the whole lamp body has more layering sense and more beautiful appearance after the lamp is lighted; the mounting posts are distributed more uniformly, and the flexible circuit board is fixed by the mounting posts, so that the circuit board is more firmly mounted.

The heat dissipation assembly comprises a heat conduction column 10 arranged in the protruding portion and the groove, the heat conduction end of the heat conduction column penetrates through the supporting bar and is in contact with the flexible PCB, and the other end of the heat conduction column is connected with the plurality of heat dissipation fins 11. Through setting up the heat conduction post with heat conduction to the heat dissipation fin on with the flexible line way board heat dissipation, the radiating effect to the flexible line way board is better.

And a heat-conducting insulating silica gel sheet 12 is arranged between the heat-conducting column and the flexible PCB. Through setting up insulating silica gel piece, have better heat conductivity on the one hand and avoid electrically conducting on the other hand.

The heat conducting end is disc-shaped. The dish-shaped, the area is big, and heat conduction is faster.

The radiating fins are distributed in a circular shape by taking the central line of the heat conducting column as the center of a circle. The radiating fins distributed in a circular shape are adopted, so that the radiating is fast and the radiating effect is good.

The flexible PCB board is connected to a power board 14 through a wire 13. And power is supplied through the power panel.

The power panel is located the support bar bottom. The power panel is arranged at the mounting position of the bottom end of the supporting bar without occupying the flexible circuit board, and the mounting space is distributed more reasonably.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
