Description

[Detailed Description of the Invention] The present invention relates to a lighting structure in a display device that is used in electrical appliances for automobiles, audio equipment, and office equipment and is equipped with a display section such as a display board and an operating section such as a lever.

Generally, in this type of display device, the display section and the operation section are individually illuminated by light sources, which not only complicates the configuration for this illumination but also requires a large number of light source storage sections. The drawback is that the display device itself cannot be made thin and cannot be made compact.

This invention was created in view of these circumstances,
The purpose is to provide an illumination structure for a display device that eliminates individual light sources, simplifies the configuration for illumination, and can be made smaller and more compact.

The present invention, which was developed to achieve this purpose, includes a rectangular display board in the center, insertion holes through which operating members such as levers are inserted at the top and bottom of the display board, and A lens for illuminating the operating member is arranged in the same direction, and a rectangular under-lens for illuminating the display board and an under-lens for lever illumination are arranged in an overlapping state on the back side of the display board, and both ends of these under-lenses are arranged to receive light. The display board illumination under-lens has a reflecting part tapered toward the center on the back surface so that the incident light from the end illuminates the display board on the front side. The under-lens for lever illumination has a reflecting part made of a substantially rhombus-shaped hole in the center so that the incident light is irradiated to both sides, and the under-lens for lever illumination has a reflecting part formed of a substantially diamond-shaped hole on both sides. A lighting structure for a display device, characterized in that lenses for member lighting are arranged so that light is introduced in surface contact with each other, the under-lens for illuminating the display board and the under-lens for illuminating the lever. When used in combination, one light source can provide both types of illumination, simplifying the internal structure and making the overall system smaller and more compact.In addition, if each underlens is colored in a different color, the color tone of the illumination can be changed. It can be changed in various ways.

Next, the present invention will be explained in more detail with reference to illustrated embodiments. Reference numeral 1 is a front panel or frame of, for example, an automobile air conditioner (near conditioner), and the front panel includes a display section, an operation section, and a light source. It has become a device.

In such a display device, a rectangular display plate 2 is provided at the center of the front surface, and insertion holes 3 and 4 are provided at the top and bottom of the display plate, into which levers (not shown) serving as operating units are inserted. Lever lenses 5 and 6 for illuminating the lever are provided near one edge in the longitudinal direction of the insertion hole.

An under lens 7 for illuminating the display board is provided on the back side of the display board 2.
and a lever illumination under-lens 8 are provided in an overlapping state, and both ends of each under-lens are capable of receiving light and facing lamp cases 9 and 10, respectively.

This lamp case is provided at both ends of the display device, and inside it is provided with lamps 11 and 12 having an appropriate luminescent color as a light source.
are arranged respectively.

The display panel illumination under-lens 7 has a back surface tapered toward the center, and is configured such that light a incident from the end is reflected toward the front surface.

The under-lens 8 for lever illumination has a diamond-shaped hole 8a formed in its center, and is configured so that light incident from both ends is reflected to both sides in the length direction, as shown in FIG. ing.

The under-lens 8 for lever illumination is in surface contact with the lever lenses 5.6 provided at the edges of the lever insertion holes 3 and 4 on both end surfaces, and the light from the under-lens for lever illumination is reflected by the lever lens 5.6. It is configured so that it is directly incident on the

With this configuration, the light from the lamps 11 and 12 is incident on the ends of the under-lens 7 for illuminating the display board and the under-lens 8 for lever illuminating, respectively, and the light from the lamps 11 and 12 is incident on the ends of the under-lens 7 for illuminating the display board and the under-lens 8 for lever illumination, respectively, and the light is transmitted through the under-lenses to the display board. 2 and lever lens 5
, 6 are illuminated at the same time, and by coloring each underlens differently, different colors of display or illumination can be achieved even with the same light source.

In particular, by using an underlens, the light guide direction can be changed in various ways, and at the same time, various types of display parts or illumination parts can be illuminated in different states.

As explained above, the lighting structure of the display device according to the present invention uses the under-lens for display board illumination and the under-lens for lever illumination as a set, so that light from the light source can be introduced to both ends of these. The introduced light is irradiated to the front side of one lens, and is irradiated to both sides of the other lens, so not only can these lenses be mounted on top of each other, but also the display unit and Since it is configured to simultaneously illuminate with the lever, there is no need to provide a separate light source for each lighting section, which simplifies the configuration and minimizes space in the thickness direction, making the overall product smaller and more compact. It has excellent effects.

Furthermore, by changing the coloring of each underlens, multi-colored illumination and display can be achieved using a common light source, and the illuminance can also be freely changed in each display and illumination section. It also has effects such as being able to provide different lighting for images.
