Problems solved by technology

[0005] In the above-mentioned conventional lamps for vehicles, since the light-emitting diodes e, e, ... are supported on the printed circuit board d, the degree of freedom in design is limited.
In other words, the shape of the printed circuit board d, especially the shape in the thickness direction cannot be freely designed, so there is a problem that a large bending structure cannot be formed in the depth direction of the lamp.
[0006] In addition, the price of printed circuit boards is high, and there is a problem of high cost due to the cost of soldering equipment and processes.
[0007] In addition, from an environmental point of view, brazing is not the best

Embodiment Construction

[0017] Next, embodiments of the vehicle lamp according to the present invention will be described with reference to the drawings.

[0018] The illustrated vehicle lamp 1 is suitable for an overhead parking light, that is, a parking light arranged inside a rear windshield of a car.

[0019] The rear end of the lens 2 of the vehicle lamp 1 is covered by the lamp body 3 to form a lamp chamber 4 composed of the lens 2 and the lamp body 3 . A front portion 2a long in the left-right direction of the lens 2 and a peripheral wall portion 2b protruding rearward from the peripheral edge of the front portion 2a are integrally formed of a red colored transparent synthetic resin. At the rear end of the peripheral wall portion 2b of such a lens 2, a lamp chamber 4 to which a substantially plate-shaped lamp body 3 can be attached is formed. A cylindrical portion 5 protruding rearward is integrally formed on the lamp body 3 .

Abstract

A vehicle lamp unit 1 in which a plurality of light emitting diodes 13 are arranged to make up a light source is disclosed. The lamp unit includes a base member 7 for supporting a plurality of the light emitting diodes, feeder wires 14 that are disposed at the reverse side of the base member and connected to lead terminals 13d of the light emitting diodes, and feeder terminals 16 connected to the feeder wires. The lamp unit advantageously realizes a cost reduction, enhances the degree of design freedom, and promotes environmental protection.

Description

technical field [0001] The present invention relates to novel lamps for vehicles. Specifically, it relates to technologies for reducing costs, increasing design freedom, and being environmentally friendly. Background technique [0002] There is a vehicle lamp in which a plurality of light emitting diodes are arranged as a light source. For example, we know that the parking lights arranged on the inside of the rear windshield of a car are elevated parking lights. [0003] However, vehicle lamps using the above-mentioned light-emitting diodes as light sources generally use Figure 6 structure as shown. [0004] That is, a printed circuit board d is arranged in a lamp chamber c composed of a lens a and a lamp body b covering the back of the lens a, and on the printed circuit board d, terminals f of a plurality of light emitting diodes e, e, ... , f, ... are supported on the printed circuit by soldering. [0005] In the above-mentioned conventional vehicle lamp, since the li...
