Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a compound light, such as a rear combination lamp, in which a plurality of lights are combined with the outer lens surface substantially flush with each other, and more specifically, the light source thereof is a combination of an LED light source and an incandescent light source. Pertains to.

[Conventional technology]

FIGS. 5 and 6 show examples of a conventional vehicle composite light 90 of this type, and this vehicle composite light 90 includes, for example, a tail light/brake light 91, a direction indicator light 92, and a reversing light 93. are combined, and a plurality of LED light emitting elements are assembled in the tail light/brake light 91.
The LED light source 91a is a direction indicator light 92 and a backing light 9.
Incandescent light sources 92a and 93a are employed for the tail lights/brake lights 91, direction indicator lights 92, and reversing lights 93, respectively, and the tail light/brake light outer lens 91b and the direction indicator light outer The lens 92b and the rearward light outer lens 93b are provided substantially flush for reasons such as the design of the vehicle composite light 90. At this time, since the LED light source 91a is composed of a plurality of light emitting elements, the distance between the tail light/brake light outer lens 91b and the incandescent light sources 92a and 9 is reduced.
3a and the corresponding direction indicator light outer lens 92b and reversing light outer lens 93b.
The LED light source 91a and the incandescent light sources 92a and 93a are provided with a step difference in the vehicle composite lamp 90.

[Problem that the idea aims to solve]

However, as described above, each light source 91
The fact that a, 92a, and 93a have the steps results in the lamps 91, 92, and 93 having independent structures, so that the composite lamp 90 requires as many steps as the combined number in the assembly process. As a result, the number of steps becomes enormous, resulting in a problem that impairs productivity, and the solution to this problem has become an issue.

[Means to solve the problem]

The present invention is a specific means for solving the above-mentioned conventional problems, and provides a composite lighting device for a vehicle in which the outer lens is made substantially flush with the LED light source lamp and the incandescent light source lamp device.
By disposing a light source and an incandescent light source on the same substrate, and disposing an LED inner lens between the LED light source and the corresponding outer lens, the LED
By providing a composite lamp for a vehicle characterized in that the appropriate distance between the light source and the corresponding outer lens is the same as the appropriate distance between the incandescent light source and the corresponding outer lens, assembly in this type of composite lamp is improved. This enables a significant reduction in the number of steps and solves the above-mentioned conventional problems.

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the reference numeral 1 in FIGS. 1 and 2 is a composite lamp for a vehicle according to the present invention (hereinafter abbreviated as composite lamp 1), and this composite lamp 1 includes a tail light/brake light outer lens 11, The tail light/brake light 10 and the direction indicator light 20 are aligned so that the direction indicator light outer lens 21 and the reverse light outer lens 31 are substantially flush with each other.
and a reversing light 30 are combined, and in addition, the tail light/
The brake light 10 employs an LED light source 12, and the direction indicator light 20 and the reverse light 30 employ incandescent light sources 22, 3.
2 is the same as the conventional example, but according to the present invention, an LED is installed between the tail light/brake light outer lens 11 and the LED light source 12.
An inner lens 13 is provided, which connects the tail light/brake light outer lens 11 and the LED light source 1.
By extending the appropriate distance between the direction indicator light outer lens 21 and the incandescent light source 22 and matching the appropriate distance between the direction indicator light outer lens 31 and the incandescent light source 32, as shown in FIG. LED on
Both the light source 12 and the incandescent light sources 22 and 32 are disposed on one substrate 2, and can be attached to the housing 3 as one unit. Note that the reference numeral 4 in the figure is a shade, which is the light source 1 disposed on the single substrate 2 described above.
This is to partition the lights from 2, 22, and 32 so that they do not mix. Here, the LED inner lens 13, which is the gist of the present invention, will be explained in more detail.
As shown in FIG. 4, this LED inner lens 13 has a so-called fisheye lens shape, with convex lens-shaped lens cuts 13a corresponding to each of the plurality of LED light emitting elements 12a provided in the LED light source 12. The effect is that the LED light emitting element 1
The tail light/brake light outer lens 11 converts the light beam having a predetermined radiation angle from 2a into substantially parallel light.
It is made to be incident on the That is, the light from the LED light source 12
Since the light is converted into parallel light by the inner lens 13, the tail light/brake light outer lens 11, which is provided in front of the LED inner lens 13, is installed in the parallel light, and the light distribution characteristics are different at any distance. The same thing can be installed anywhere. With the above configuration, the tail light/brake light outer lens 11 and the direction indicator light outer lens 21
Even when the backlight outer lens 31 and the backlight outer lens 31 are in the same plane, one incandescent light source 22 (hereinafter, an example on the direction indicator light 20 side will be explained, but the same applies to the backlight 30) and the Fresnel inner lens. 23 and an incandescent light source 2 that requires a relatively deep depth to cover the entire surface of the direction indicator light outer lens 21.
This makes it possible to match the distance between the LED light source 12 and the tail light/brake light outer lens 11 with the appropriate distance between the LED light source 12 and the direction indicator light outer lens 21.
32 on one substrate 2. Furthermore, the LED light source 12 is mounted on the single board 2 described above.
By making it possible to arrange the incandescent light sources 22 and 32, it is possible to use a printed circuit board or the like for the board 2 and to wire and connect all the light sources 12, 22, 32 in advance. This makes it possible to consolidate all external connections, such as power supplies, into one location.

[Effect of the idea]

As explained above, with this invention, by attaching an LED inner lens to the LED light source side,
The distance between the LDE light source and the corresponding outer lens is extended, the distance between the incandescent light source and the corresponding outer lens is matched, and the LED light source and the incandescent light source are mounted on the same board. By making it possible to integrate all light sources and connecting to an external power source in one place, it is possible to reduce the number of parts and assembly man-hours, thereby making it possible to produce this type of composite vehicle lighting. This has an outstanding effect on performance improvement and cost reduction.
