Description

  The present invention relates to a corner light in which LED lighting for illuminating a luggage compartment of a vehicle such as a truck is installed in a corner portion on the ceiling side of the luggage compartment.

  2. Description of the Related Art Conventionally, there is a vehicular lighting fixture that lights a luggage compartment or a cargo compartment of a vehicle such as a truck (for example, a lighting fixture described in Patent Document 1). Patent Document 1 discloses a vehicle lighting device that includes a main body that houses a light source for illumination and a glove formed so as to cover the main body, and is provided near the ceiling of a passenger cabin inside the vehicle. . In this vehicular lighting fixture, a cover that covers a fluorescent lamp is formed of a lightweight resin material to reduce costs and improve maintainability.

  Recently, instead of conventional incandescent bulbs and fluorescent lamps, LED luminaires with low power consumption and long life have been used. As shown in FIG. 7, for example, there is a substantially rectangular LED illumination unit R ′ having a plurality of LED light sources inside the unit main body, and this is used as a vehicle lighting device that illuminates the inside of the luggage compartment 10 a of the vehicle A ′. A plurality of them were installed at predetermined pitches on the side walls and ceiling of the truck room.

[Patent Document 1] Utility Model Registration No. 3165125

  However, as shown in FIG. 7, the conventional LED lighting unit R ′ is arranged scattered on the ceiling portion 17 and the left and right side wall portions 16a and 16b of the luggage room 10a. The portion to be illuminated became local, and there was a dark spot on the floor 18 at the center between the units, and the entire interior of the luggage compartment 10a could not be illuminated with uniform illuminance.

  In addition, condensation occurs on the mounting bolts for fixing the LED lighting unit R ′, and water droplets due to the condensation fall on the luggage stacked in the luggage compartment, so that the luggage may get wet and cause damage. In addition, the mounting bolt may be dropped from the LED lighting unit R ′ due to vibration during travel, and the dropped mounting bolt may be mixed into the luggage in the luggage compartment.

  An object of the present invention is to provide a corner light that does not take up a large number of installation locations and that lights the entire luggage compartment without obstructing the load in the luggage compartment.

Therefore, the device according to claim 1 is a circuit board in which a plurality of LED light sources that are turned on by supplying electricity from a battery power source are arranged at a predetermined pitch, and a transparent protective plate that protects the circuit board from above. The circuit board and the substrate support that supports the protective plate are integrated to form a corner light, and the previous substrate support is formed in a long and substantially U-shaped cross section and has a ceiling-side corner. part of the end portions includes a flange portion is extended outward in length covering the, attached to the ceiling side corner portion of the cargo compartment of the vehicle the corner light via a mounting member, the mounting member, the L-shaped An intermediate piece that is formed into a long shape with a cross-sectional shape and that has a right-angled sharp end at a flat shape, and an intermediate piece-side screw hole through which a mounting bolt for mounting the mounting member can be inserted. that was Is a corner light, characterized.

Devised according to claim 2, each side of the L-shaped to form the mounting member, Ri prearranged strength members der to secure the side wall portion and a ceiling portion constituting the loading space, said substrate The support body has a bottom wall portion side screw hole through which the attachment bolt can be inserted in the bottom wall portion having a substantially U-shaped cross section, and the attachment bolt together with the intermediate piece side screw hole formed in the attachment member. The corner light according to claim 1, wherein the corner light is configured to be integrally attached to the ceiling side corner portion .

  According to the first aspect of the present invention, since the LED light source is disposed via the mounting member at the ceiling-side corner portion of the luggage compartment or the like of the vehicle, a wide area is illuminated from the ceiling-side corner to the floor and side surfaces of the luggage compartment. be able to. In addition, since the LED light source is provided at the ceiling-side corner portion, the LED light source can be disposed without hindering the luggage stacked in the luggage compartment, and the luggage can be stacked near the ceiling in the luggage compartment. Furthermore, by arranging the corner light over the entire surface of the ceiling-side corner portion, the entire luggage compartment can be illuminated uniformly. In addition, when the room is partitioned by partitions, the illuminance of each partitioned room can be made the same regardless of the partition position.

Furthermore, corner lights can also be applied to wing cars. In addition, in temperature control vehicles such as freezer cars and cold storage warehouses, conventional indoor lights in freezers have been dug into ceiling insulation, but corner lights do not need to be dug into such insulation, There is no need to worry about the decrease in cold insulation performance due to digging into the insulation. In addition, since the LED light source is arranged at the ceiling-side corner so as to be approximately at the center position of the angle formed by the ceiling and the side wall, the light emitted from the LED light source has an irradiation range of a predetermined angle. By disposing this on the entire surface of the ceiling-side corner portion of the luggage compartment, it is possible to illuminate a wide area from the ceiling-side corner to the floor and side surfaces of the luggage compartment.

  According to the invention described in claim 2, since the reinforcing member provided in advance on the ceiling-side corner portion is used as a corner light mounting base, the mounting base serves as a strength member for fixing the ceiling portion and the side wall portion. In addition to functioning, it has the effect of functioning as a corner light mounting member. Moreover, it can arrange | position in the ceiling side corner part which is not received by the influence of a load with this attachment base, Thereby, the attachment space which attaches an LED light source can be used effectively.
