LED lighting fixtures for car speakers}

The present invention relates to an LED lighting fixture for automobile speakers, and more specifically, to an LED lighting fixture that is mounted on a speaker mounting portion of a automobile door trim and illuminates the interior of a automobile.

As the automobile tuning market becomes more active, a variety of automotive interior lighting fixtures are being released.

For example, there are vehicle lighting fixtures that are used by inserting them into gaps in car door trims, dashboards, or gearboxes.

In Patent Document 1, a ferrite magnet 12 is disposed on the outside of the lower plate 10, a frame 14 is located on the upper side of the magnet 12, and a conical diaphragm 18 is disposed on the inside of the frame 14. The outer periphery of the diaphragm 18 is adhered to the outer peripheral surface of the frame 14 via the edge 20, and a ring-shaped substrate 30 is disposed on the outside of the frame 14. A plurality of light emitting sources 32 are mounted on one side at regular intervals, and the plurality of light emitting sources 32 disposed on the annular substrate 30 are edged through open portions formed between adjacent frame supports 16. 20), the mood lamp of the vehicle door speaker located close to the rear is described.

Patent Document 1 states that since the light emitting source is mounted on the back of the diaphragm, it is difficult to use if the edge of the diaphragm is not made of a transparent or translucent material. Since the light emitting source is mounted on the back of the diaphragm, it cannot be easily installed, and mood lamps of various shapes are used. There is a problem that cannot be provided.

Meanwhile, in the case of imported cars, some products provide LED lighting for small speakers located in front or on the side of the dashboard, but the disadvantage is that they cannot be installed quickly as the LED modules are simply attached using adhesive along the perimeter of the speaker. This exists.
