And a sign image that displays an accurate sign in the vertical direction.

The alerting is increased even in the daytime by blinking the light source or the blinking device.

Further, the present invention is characterized in that fine semi-cylindrical optical lenses are evenly arranged to form a sheet, and a visible range is limited by a viewing angle, and a plurality of images are inserted into one image.

Effect of the invention

The present invention promptly informs the elderly and drivers who have reduced their normal judgment ability due to fatigue by displaying entry prohibition or one-way on the same screen and reverse entry to ordinary roads and highways. It can prevent traffic accidents or make it possible to recognize abnormal behavior at an early stage.

In addition, the present invention stops the display of a normal driving action for both vehicles with a single sign lamp as a sign light on a narrow road in the Tokyo metropolitan area, and the continuation of driving action against dangerous and reverse running vehicles. It is possible to make it.

The present invention improves the awareness of crisis more effectively by installing a flashing light source device in the eyes of the driver.

When installed at an airfield, it is possible to accurately inform a landing-ready aircraft of a slight difference (minus or plus) in the runway approach angle.

It is an instruction | indication which shows the marker lamp concerning this invention. Is a front view showing an example of a sign image. (A) is a one-way sign (b) is an entry prohibition sign (c) is a reverse running prohibition. (A) is a side view (b) is a top view. It is a principle explanatory view of a 2D image using a lenticular lens. It is a schematic diagram which shows the installation state to the road for vehicles. It is the schematic which shows the installation state to the road for vehicles with a dangerous sharp curve. It is a schematic diagram which shows the installation state to the runway of an airfield.

As shown in FIGS. 1 to 4, the sign lamp according to the present invention replaces various sign designs with image data, and looks at image data processed into a plurality of lines according to the size of the lenticular lens 1. It is a sign that is recognized as a sign image 2 that displays accurate signs in the left and right and up and down directions on the same screen that can be recognized in the direction of, but not in the difference in the image of the eye level difference level.

The sign image includes a one-way sign 2 (2a) as viewed from the left as shown in FIG. 2 (a), and an entry prohibition sign 2 (2b) as viewed from the right as shown in FIG. 2 (b). 2) in FIG. 2 (c) can be visually recognized as a reverse running danger sign 2 (2c) viewed from the right direction.

As shown in FIG. 2 (a), the indicator lamp uses a lenticular lens divided into a linear shape and an LED light source (FIG. 3-3) as a light source, and the sign design is replaced with image data.
