A substrate 130 is seated on the upper surface of the body 110. A movement 112 is mounted on the center of the upper surface of the substrate 130 and four light sources 114 are mounted around the movement 112. The power supplied through the connector (not shown) is applied to the movement 112 and the light source 114 via the substrate 130 to actuate the movement 112 and light the light source 114, respectively.

A dial plate 150 is installed on the upper part of the movement 112 and a first prism 140 is interposed between the movement 112 and the dial plate 150. That is, the first prism 140 is mounted on the upper part of the movement 112, and the dial plate 150 is installed on the upper part of the first prism 140.

The dial plate 150 has a disk shape having a predetermined diameter. On the upper edge of the dial plate 150, various indices 154 indicating time and minute are provided. A shaft connected to the movement 112 passes through the center of the dial plate 150, and a clock needle 156 is installed on the shaft.

The first prism 140 serves as a light distribution light for illuminating the lower portion of the dial plate 150. That is, the light generated from the light source 114 is dispersed and refracted to concentrate on the lower surface of the dial plate 150. The light guided through the first prism 140 is transmitted to the upper portion (front side) of the dial plate 150 to form a backlight illumination.

The first inclined surface 152 and the second inclined surface 142 are formed on the upper surface of the dial plate 150 and the first prism 140, respectively.

The first sloped surface 152 and the second sloped surface 142 allow a portion of the light guided through the first prism 140 to be concentrated so that the index 154 of the dial plate 150 emits brighter light . In other words, the first inclined surface 152 and the second inclined surface 142 are formed to improve the visibility of the index 154, and to form an obtuse angle with respect to the front surface of the dial plate 150.

Referring to FIGS. 5 and 6, when power is supplied to the substrate 130 through a connector (not shown), light is generated in the light source 114. Light generated from the light source 114 is irradiated upward, and a part of the light is guided by the first prism 140 to form a light distribution illumination, and the remainder is guided to the second prism 160 to form a light metering illumination.

A part of the light incident on the first prism 140 moves toward the center of the first prism 140 to brighten the central part of the dial plate 150 and the other part illuminates the edge of the first prism 140 Slope 142) to illuminate the index 154 brightly. Another part of the light introduced into the first prism 140 moves toward the edge of the first prism 140 and flows toward the second prism 160, thereby functioning as a light-metering light.

The light introduced into the second prism 160 and the light introduced from the first prism 140 are irradiated toward the dial plate 150 through the diffusion protrusions 162. Light illuminated in the upper and horizontal directions in the drawing improves the visibility of the dial plate 150 and the light directed downward improves the visibility of the index 154.

The vehicle watch 100 according to the present embodiment realizes both the light distribution illumination and the light metering illumination through the first prism 140 and the second prism 160 to concentrate a large amount of light on the dial plate 150 . Therefore, not only the center of the dial plate 150 but also the edge where the index 154 is provided can be improved in visibility, so that time information can be stably provided during the day and night.

Since the diffusive protrusions 162 are irradiated toward the index 154 side of the dial plate 150 to enhance the visibility of the light incident on the second prism 160 and the light incident on the first prism 140, 154) The related parts can be made of various materials. For example, an opaque metal-based index 154 can be applied to create a more luxurious feel.
