DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminous pointer for illuminating a pointer for satisfactorily judging a measured value such as a traveling speed in an instrument for a vehicle, and a lighting device therefor.

[0002]

2. Description of the Related Art In general, an instrument illuminating device of this kind has a structure in which, for example, an instrument main body is provided in a case and a rotary shaft of the instrument main body is provided in order to determine a measured value such as a traveling speed at night or the like. An indicator that fixes the hands and forms a light-shielding print layer on the front side of the instrument body, excluding characters, numbers, and scales, on a light-transmitting substrate to make the letters, numbers, and scales light-transmitting. A display device having a display panel formed with a pointer, a pointer device is rotated on the display plate on which the index portion is formed, and an instrument device that displays a measured value such as a traveling speed by reading the contrast between the pointer and the index portion is configured. Light from a light source provided inside is transmitted from the light-transmitting index portion toward the front surface of the display panel to illuminate characters, numerals, scales, and the like serving as the index portion.

In order to illuminate the hands, for example, in Japanese Utility Model Publication No. 5-15058, a light guide plate is provided on the back side of the display plate, and about 4 mm is provided around the hole for inserting the pointer shaft of the light guide plate.
A reflecting surface inclined at 5 degrees is formed, a part of the display plate corresponding to the position of the reflecting surface is cut out in a circle, and the upper surface of the light guide plate is exposed toward the hands, and the base of the hands provided on the display plate Is provided with a light receiving portion for receiving light emitted from the reflecting surface of the light guide plate toward the hands and a reflecting surface inclined at about 45 degrees for reflecting and guiding the light toward the tip of the indicating portion of the hands. Thus, the display panel is illuminated via the light guide plate by turning on the light source inside the case, and at the same time, the hands can be illuminated.

[0004]

However, according to the above configuration, in order to make the pointer emit light brightly, it is necessary to efficiently reflect and guide the light from the light source through the light guide plate and the reflecting surface of the pointer base. In the design of the reflecting surface, there is a problem that it takes time to perform an optical path analysis or the like, and that forming the reflecting surface increases the cost of a mold.

[0005] In addition, this type of instrument device sometimes employs a lighting structure of a type in which the surface of a display panel and hands are illuminated by light from the front of the display panel. That is, as shown in JP-A-53-127758, a light source provided in a case for transmitting and illuminating the indicator portion of the display panel is provided, and light from this light source is transmitted through a transparent acrylic or the like. A light member guides the display panel front side along the inner wall of the case, and an end of the light guide member is exposed from a hole of the case to form a light emitting portion, and light is emitted from the light emitting portion to the display panel surface side. Irradiation is performed by illuminating the display panel surface and the pointer surface with this irradiation light.

In this structure, as compared with the above-described pointer illumination structure, the light guide plate and the pointer do not need to have a reflecting surface for pointer illumination, and the structure is simplified, but in this case, the pointer is made of a light-shielding member. For this reason, there is a problem that the shadow of the pointer is generated on the display panel due to the illumination from the front side of the display panel.

Further, as other pointer lighting structures, a light source is built in the base of the pointer to reflect and guide the light toward the transmissive indicator, or a plurality of LED chips are built in along the indicator of the pointer. Although it is proposed to emit light by emitting light, the assembly is complicated, and power is supplied to the inside of the rotating pointer. .

Although many of the above-mentioned pointer illumination systems have been generally proposed in pursuit of uniformity of brightness and brightness of a pointer which emits light, the display form of the pointer which emits light is generally flat and lacks in interest. There were many things.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple pointer illumination structure and to provide a luminous pointer with good visibility without causing a shadow of the pointer on the display panel.
It is an object of the present invention to provide a light-emitting indicator and a lighting device thereof that form a new display form.

[0010]

In order to achieve the above-mentioned object, the present invention is arranged in front of a display panel having an indicator portion indicating a predetermined physical quantity, and receives the irradiated light to emit the light. In the light emitting pointer for indicating the index portion of the plate, a rod-shaped indicating portion for indicating the index portion of the display plate and a pointer fixing portion which can be fixed to the rotating shaft of the instrument body are integrally provided, and the finger is provided.
Light can be received over almost the entire length including the needle fixing part and the pointing part.
Made of transparent material that can transmit light, and its cross-sectional shape
Is a narrow guide book from the display panel facing surface side to the surface side.
It is formed by the body .

The pointer body is made of a chromatic color translucent material other than black.

Further, the pointer main body has a light receiving portion having a flat surface for receiving light on a surface facing the display panel in a sectional shape thereof.

The pointer body is formed such that its thickness and width are gradually reduced in the length direction with the pointer fixing portion as a base point.

[0014] The light-receiving portion may be configured such that the pointer fixing portion and the bottom portion of the pointing portion are on the same plane, and have a flat surface provided in parallel with the display panel.

The pointer main body is made of a plurality of chromatic translucent materials having different colors or transmittances.

Further, a display plate having a ground color surface with high brightness and forming an index portion representing a predetermined physical quantity, a rod-shaped indicating portion for indicating the index portion of the display plate are provided, and a rotating shaft of the instrument main body is provided. A pointer body formed of a pointer fixing portion that can be fixed to the pointer body, the pointer body receives light of the display panel over substantially the entire length and is integrally formed from a transparent material capable of transmitting light, and has a cross-sectional shape. A light receiving portion made of a flat surface is formed on a surface facing the display plate, and the display plate pair is formed .
It is formed so as to be narrower from the light receiving section on the opposite side toward the front side .

[0017] Further, the display plate is made of a color brighter in brightness than the color of the pointer main body over substantially the entire surface of at least the rotation range of the pointer main body.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION On a substrate made of a light-transmitting material, a ground color layer made of a light-transmitting bright color is printed on the entire surface, and characters, numerals,
A display plate is provided in which an index portion such as a scale is formed by light-shielding printing, and a light guide plate is provided on the back side of the display plate. A light source is provided at one end of the light guide plate, and substantially the entire surface of the display plate is illuminated with the ground color of the display plate by a so-called edge light method in which light is introduced into the light guide plate by turning on the light source. Like that.

On the back side of the light guide plate, an instrument main body composed of a bobbin type instrument or the like is provided, and the rotation axis of the instrument main body is provided so as to penetrate the light guide plate and the display plate. A pointer main body made of a transparent material is fixed to the tip of the rotating shaft of the instrument main body, and the pointer main body rotates along an index portion formed on the display panel to indicate a measured value.

At this time, the pointer main body includes a pointer fixing portion fixed to the rotating shaft of the instrument main body, and a rod-shaped indicating portion pointing to the index portion of the display panel, and extends over substantially the entire length of the indicating portion and the pointer fixing portion. It is integrally formed of a chromatic color translucent material capable of receiving and transmitting light.

In the present embodiment, the pointer is illuminated by receiving light from the display panel, which emits light over substantially the entire surface at least over the rotation range of the pointer, and transmitting this light inside the pointer. The hands emit light in a chromatic color by the light of the display board that is brighter than the hands.

Accordingly, since the light emitted from the display panel, which is entirely illuminated, is used as it is for illumination of the hands, the hands can be made to emit light with a simple lighting structure, and the cost can be reduced. In addition, the degree of freedom of the pointer shape is increased, and a slim and simple pointer can be designed.

Further, since the display panel has a ground color layer having a higher brightness than the pointers printed on the entire surface, even in the daytime when the light source is not turned on, the external light reflects on the display panel. The pointer is illuminated in chromatic colors.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of the present invention.

A base layer made of a light-transmitting bright color is printed on the entire surface of a substrate made of a light-transmitting material, and an index portion 1A consisting of characters, numerals, scales, and the like representing a predetermined physical quantity is printed by light-shielding printing. A display panel 1 is provided, and a light guide plate 2 is provided on the back side of the display panel 1. A light source 3 is provided at one end of the light guide plate 2.
The light source 3 is turned on and the light from the light source 3 is introduced into the light guide plate 2 at night or the like when the surroundings are dark. The area is made to emit light with the ground color of the display panel 1, and the light-shielding indicator 1A is visually recognized in the area.

The light guide plate 2 is formed so as to gradually decrease in thickness from one end where the light source 3 is provided to the other end, so that the entire display plate 1 emits light substantially uniformly. At the same time, a white or silver reflector 4 is printed and formed on the back side of the light guide plate 2 so that light guided inside the light guide plate 2 can be reflected favorably toward the upper display plate 1. Make up.

Inside the case 5 on the back side of the light guide plate 2, an instrument body 6 composed of a bobbin instrument, a stepping motor, and the like is provided.
The rotating shaft 7 of the instrument main body 6 is provided so as to penetrate toward the front surface of the display panel 1 through holes 8 and 9 formed in the display panel 1 and the light guide plate 2.

A pointer main body 10 made of a transparent material is press-fitted and fixed to the tip of the rotating shaft 7 of the instrument main body 6, and the pointer main body 10 rotates along the indicator 1 A formed on the display panel 1. To indicate the measured value.

At this time, the pointer main body 10 is integrally formed of a pointer fixing portion 11 fixed to the rotating shaft 7 of the instrument main body 6 and a rod-shaped indicating portion 12 pointing to the indicator 1A of the display panel 1. Further, the pointer main body 10 is made of a light-transmitting material made of a chromatic color other than black that can receive light and transmit light over substantially the entire length including the pointer fixing portion 11 and the pointing portion 12.

In the present embodiment, the pointer main body 10 is different from the light emission color of the display panel 1 in order to increase the contrast of the pointer main body 10 with respect to the background of the light emitting display panel 1 and emit light. Formed of chromatic translucent resin material,
The light of the display panel 1 is received and transmitted into the pointer main body 10, and the color of the transparent material of the pointer main body 10 causes the pointer main body 10 to emit light.
Is configured to emit light. That is, in the present embodiment, while the luminescent color of the display panel 1 based on the ground color is white, the pointer main body 10 is made of a light-transmissive red transparent resin material to display the pointer main body 10. The plate 1 is configured to be colored red to be different from the white light emission color of the plate 1 so as to perform transmitted illumination. At this time, since the pointer main body 10 takes in the light of the display panel 1 which emits light from the entire surface into the pointer main body 10, and transmits and illuminates the light, the emission color of the display panel 1 is set to a color brighter than the color of the pointer main body 10. The display panel 1 is formed with a transparent white ground color layer such as white or cream. In this case, the ground color layer formed on the surface of the display panel 1 is desirably formed by printing a white color or a metallic color having a bright color.

Therefore, since the light emitted from the display panel 1 which is totally illuminated is used as it is for illuminating the pointer main body 10, the pointer main body 10 can be illuminated with the simplest illumination structure, and the cost can be reduced.

In the daytime when the light source 3 is not turned on, the ground layer having high brightness of the display panel 1 is
Since the external light is satisfactorily reflected on the surface of the pointer body 10, the reflected light is received inside the pointer body 10, and the pointer body 10 transmits and emits a chromatic color.

Since the pointer main body 10 is made of a transparent material, even if the pointer main body 10 blocks the index portion 1A such as characters, numerals, and scales, the pointer main body 10 is made of a transparent material.
It is also possible to see through the indicator portion 1A formed on the display plate 1 as it is, and it is also possible to easily read and compare the pointer main body 10 and the indicator portion 1A of the display plate 1.

The pointer main body 10 is a light receiving section 14 having a flat surface 13 at a portion facing the display panel 1. In this case, the pointer fixing section 11 and the bottom section 15 of the pointing section 12 are coplanar. The light receiving portion 14 that receives light from the display panel 1 is formed by being disposed in parallel with the display panel 1 that emits light. The cross-sectional shape is formed narrower from the light receiving portion 14 on the surface facing the display panel 1 toward the surface side, and the surface side is formed as a convex curve, so that the surface facing the display panel 1 is flat. The illuminating light incident from the light receiving unit 9 composed of the surface 13 is converged toward the front surface side by both side surfaces of the pointer main body 8 and causes the pointer main body 8 to emit light brightly.

At this time, the pointer main body 10 is composed of a three-dimensional pointer main body 10 made of a chromatic transparent material, and the pointer main body 10 is directed from the display panel 1 toward the driver according to the rotation angle position of the pointer main body 10. The path of the light passing through the inside changes, the line of sight changes, the amount of transmitted light changes continuously, and the reflection and scattering of light on the inner surface of the pointer body 10 or the surface of the pointer body 10 causes the rotation of the pointer body 10. The pointer body 10 rotates while continuously changing the emission color according to the
A new display form of light emission of the pointer main body 10 can be provided, and the design is excellent.

Further, according to the present invention, it is not necessary to provide a reflecting surface or a light source at the base of the pointer body 10 as in the prior art.
It is possible to eliminate or reduce the size of the pointer cap for covering the reflection surface and the light source, thereby realizing a slim appearance of the pointer, and increasing the degree of freedom of the pointer design.

At this time, the pointer main body 10 is attached to the pointer fixing portion 11
By making the thickness and width gradually thinner in the length direction from the base point, the entire pointer main body 10 can be designed to be slim, and the tip of the pointing portion 12 for indicating the angle can be sharpened, so that accurate physical quantity display is possible. . Conversely, since the pointer fixing portion 11 is the thickest in both thickness and width, the press-fit strength of the rotating shaft 7 can be maintained, and the hole 8 for inserting the rotating shaft 7 formed in the display panel 1 is thickened. Pointer fixing part 11
And the appearance can be prevented from being deteriorated.

FIGS. 4 to 6 show a second embodiment of the present invention, in which a display panel 1 on which a white translucent ground color layer having high brightness is printed and formed on the entire surface is provided. A light source 16 composed of an EL luminous body is provided on the back side of the display panel 1. When the light source is not turned on in the daytime, the display panel 1 reflects white light due to the reflection of external light on the surface of the display panel 1 and emits light. The display panel 1 is transmitted and illuminated with the light from the light source 16 by turning on the EL luminous body as the light source 16 so that the display panel 1 emits blue-green light.

On the other hand, in the present embodiment, the pointer body 10 has two kinds of colors including a central portion 17 made of, for example, a red translucent material and a peripheral portion 18 made of a green translucent material 18. Resin molding is performed integrally using different translucent materials.

With the above configuration, for example, when the light source 16 is not turned on in the daytime, the display panel 1 is surface-reflected by external light and emits white light. In the background of the display panel 1, the center portion 17 of the pointer body 10 becomes red. The peripheral portion 18 emits green light and is visually recognized.

At night, the display panel 1 emits blue-green light by the light of the light source 16 composed of an EL luminous body. In the background of the blue-green display panel 1, the center portion 17 of the pointer body 10 is red and the peripheral portion is 18 emits green light and is visually recognized. However, in this case, unlike the light emission in the daytime, the center 17
The red color is a form in which the color is canceled out and emits light dimly, and the green color of the peripheral portion 18 is assimilated with the background color, resulting in a low contrast state. Then, only the dim red portion of the central portion 17 is prominently illuminated in a silhouette tone, and the pointer main body 10 is visually recognized as thin as compared with the daytime. In this way, the display mode of the pointer main body 10 can be variously changed day and night in combination with the background color.

In this case, the two kinds of light-transmitting materials may be different in color, as in the present embodiment, may be different in transmittance, or may be a peripheral material. The setting of the color of the part and the center part may be reversed, and the arrangement, size, shape, and the like of these translucent materials may be appropriately selected.

Further, in this embodiment, a single light source made of an EL luminous body is provided, and the display form of the pointer is changed between daytime when the light source is not turned on and nighttime when the light source is turned on. However, for example, two kinds of light sources having different emission colors are provided, and two kinds of translucent materials having a similar color and a complementary color with respect to the light source color are selected to form the pointer body.
The light source is provided so as to be switchable and lightable, and a part having a color similar to the light source color of the pointer body emits a chromatic color while the other part having a complementary color relationship with the light source color emits a dark color by switching the light source. It can also be switched and displayed alternately.

According to the light emitting guide of the present invention, the display panel 1 in which a light-transmitting ground color layer is formed on a light-transmitting substrate is provided.
Is provided to illuminate the translucent pointer main body 10 in the daytime or at night by light emission of the display panel 1 due to reflected light of the display panel 1 or transmitted light from the light sources 3 and 16, When the display panel 1 is made of a light-shielding material, a high-brightness ground color layer is provided on the surface of the display panel 1 so that the pointer body 10 is illuminated in the daytime by reflected light of the display panel 1 due to external light. Alternatively, when a light source is used, the light is reflected on the surface of the display plate 1 by direct light from the light source from the front surface of the display plate 1 or indirect light from the light source in the case. The pointer body may be provided so as to be illuminated by the reflected light from the surface of the plate 1. In this case, it is desirable that the ground color layer formed on the surface of the display panel 1 is formed by printing a white color or a metallic color having a bright color.

The present invention is most useful when the above-described pointer body is applied to a structure in which almost the entire surface of the display panel 1 is formed of a ground color layer having high brightness, or a structure in which almost the entire surface of the display panel emits light. Not only in the form of the display panel 1 but also in the pointer main body 10 alone, by its configuration, it is possible to emit light not only from the light from the display panel 1 but also from external light, for example, external light, direct light or indirect light from a light source. This has an effect not found in the configuration.

Also, by adjusting the amount of transmission of the chromatic translucent pointer main body 10, the illumination form of the instrument can be changed. For example, the transmittance of the display panel 1 is high with respect to the background where the entire surface of the display panel 1 emits light. The display plate 1 and the pointer main body 10 can be made to emit light brightly at the same time by providing the translucent pointer main body 10, and the display panel 1 that emits bright light by providing the translucent pointer main body 10 having a low transmittance. Pointer body 10 against the background of
Can be displayed dimly and displayed in a silhouette tone. In the same manner, by appropriately selecting the color of the transparent material of the pointer main body 10 with respect to the luminescent color of the display panel 1 in a relationship between, for example, similar colors and complementary colors, the display panel 1 and the pointer main body 1 are selected.
It is also possible to make the pointer body 10 emit light dimly with respect to the display panel 1 which emits bright light simultaneously with the display panel 1 which emits light brightly, thereby displaying a silhouette tone.

In the present embodiment, the pointer main body 10 is set to a chromatic color different from the light emission color of the display panel 1 in order to increase the contrast of the pointer with respect to the background of the display panel 1 which emits light. The light of the display panel 1 is received in the pointer main body 10 and transmitted therethrough so that the pointer main body 1
Although the pointer main body 10 is configured to emit light by the color of the transparent material of 0, the display panel 1 emits light when it is desired to lower the contrast of the pointer main body 10 with respect to the background of the display panel 1 that emits light. By selecting the pointer main body 10 made of a transparent material having a similar color to the color, an illumination system that gives a soft impression as a whole may be adopted.

In order to improve the lighting effect, the pointer body 8 may be compounded with a fluorescent pigment or made of a light-scattering resin. A diffusion process may be performed.

The surface of the chromatic translucent pointer main body 10 is subjected to aluminum vapor deposition to reflect and emit silver light by daylight in the daytime, and the display panel 1 emits light when the light source is turned on at night or the like. By receiving the light from the display panel 1 and transmitting the light to the front side, the pointer main body 10 may transmit and emit light in a chromatic color of a transparent material.

When a ground layer having high brightness formed on the display panel 1 is provided on a translucent substrate, the ground color layer may be provided on the surface. It may be provided on the back surface.
