DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicator for changing the emission color used for an instrument on an instrument panel of an automobile or the like.

[0002]

2. Description of the Related Art Conventionally, in the above instrument, red zone printing is performed in order to preliminarily indicate a performance limit of a vehicle such as a warning of a high engine speed and a high temperature, a warning of a remaining fuel amount, and the like.
In addition, a light-emitting indicator that stands out even at night is used.

[0003]

The problem to be solved is that visibility is particularly poor at night compared to daytime. In addition, it is easy to perform side-by-side driving by visually following whether or not the pointer of the meter has reached the start point of the red zone, and the visual following is troublesome. Although it is printing, the presence or impression given to the driver is low. In addition, the light-emitting hands only emit light of a single color, and the movement of the hands (the running state of acceleration or deceleration)
Was by visual follow-up, as if the pointer had moved from that position to this position. For this reason, in a driving technique involving complicated shift operation and accelerator operation, the visual guidelines described above should be used in order to refer to the trend of the engine speed as a single reference for coordinating advanced driving operations. The line did not catch up.

[0004]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the present invention provides a light emitting instrument utilizing a combination of a black light and a fluorescent pigment. The purpose of the present invention is to provide a guideline for changing the luminescent color, which is characterized by being provided in a luminaire.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a bar-shaped pointer (1) having a triangular cross section is provided, and one side of the pointer (1) (2)
There is a resin material mixed with red fluorescent pigment to inform danger (3)
Is applied, and the other side surface (4) is coated with a blue fluorescent pigment-mixed resin material (5) for notifying safety. A black light (6) (near-ultraviolet light emitting lamp) serving as a light source is installed on the ceiling surface (8) of the instrument panel box (7). still,
As the fluorescent pigment used for the red fluorescent pigment-mixed resin material (3) and the blue fluorescent pigment-mixed resin material (5), those that display white when receiving daylight are used.

In the embodiment shown in FIG. 1, when the pointer (1) is located in the safety area (S), near-ultraviolet rays from the black light (6) installed on the ceiling of the instrument panel box (7) are applied to the side (4). ) Receive. The blue fluorescent pigment-mixed resin material (5) on the side surface (4) that has received near-ultraviolet light fluoresces blue, and this light is acted upon by the prism to cause the upper surface (9) of the pointer (1) to emit blue light. Make the driver recognize it as if it were. However, when the pointer (1) enters the warning area (W) where warning such as engine speed, temperature, fuel remaining amount, etc. is required, the red fluorescent pigment (3) on the side surface (2) fluoresces, and Through such an action, the driver recognizes the upper surface (9) of the pointer (1) as if it were emitting red light.

[0007]

According to the present invention, it becomes easy to recognize even the nighttime visibility is poor by changing the color. From the contrast observation by visual follow-up whether the meter pointer has reached the start point of the red zone, since the pointer itself changes its color, the driver can recognize the current situation very quickly and observe until the recognition is completed The operation time can be reduced as much as possible. There is no malfunction of color development except for the black light lamp being cut off, the color change of the pointer can be achieved with a simple structure, and the pointer changes from a single color emission to multiple colors, so it is an excellent design effect It exerts a warning prediction effect.
