Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a compound color lamp lens for a vehicle signal light, interior furniture, etc., through which bulb light emission from the inside is transmitted.

[Prior Art] As a lamp lens of this type, as shown in FIG. 3, for example, at the turn signal of an automobile, the whole or a part of the orange lamp lens 2 which transmits the light emitted from the bulb 1 is smoked by gray coating. Or, or smoked acrylic 3
It is well known that the embedded.

[Problems to be solved by the device]

As a result, a shadow due to the difference in brightness occurs on the lens surface,
Further, in order to further enhance the design effect, no device has been conventionally made to make the lens color itself look beautiful or vivid.

Therefore, it is an object of the present invention to provide a lamp lens of the kind described at the beginning that makes the lens color itself look beautiful with a composite color.

[Means for Solving the Problems]

In order to achieve this object, the present invention provides a colored transparent synthetic resin in which the cross-sectional area in the lens surface direction is changed in at least two stages at a plurality of dispersed positions in the vertical and horizontal directions of the lens surface. One lens portion (11) and the other lens portion (12) of a translucent synthetic resin of a different hue having a corresponding step shape and different in lightness are integrally formed in a plate shape.

[Action]

When viewed in the thickness direction of the lamp lens (10), both lens parts (1
By changing the ratio of 1 and 12) in two or more stages at the vertical and horizontal dispersion positions of the lamp lens 10, a dispersed pattern in which the lightness and the hue are changed stepwise is formed on the lens surface.

[Example of device]

1 and 2 show an embodiment in which the present invention is applied to a turn signal lamp lens in an automobile.

In FIG. 1, reference numeral 10 denotes the lamp lens, which is an orange acrylic lens body, and which has a lens portion 11 whose cross-sectional area in the lens surface direction changes at a matrix-like dispersion position, and a corresponding step shape. Therefore, it is integrally formed into a plate shape from the yellow acrylic lens portion 12 which is another hue having a higher lightness.

That is, the lens portion 11 has a cylindrical central portion 11a having a diameter of, for example, 1 mm exposed from the back surface in a circular dot shape, and a cylindrical stepped portion 11b having a gradually increasing cross-sectional area in the lens surface direction.
And a common base 11c. On the other hand, the lens part 12 is the lens part without changing the lens thickness.
The top portion 12a, the step portion 12b, and the base portion 12 are filled so as to fill the gap of 11.
It is formed from c.

In the lamp lens 10 having such a structure, after molding the lens portion 11, as shown in FIG. 2, yellow acrylic is injected into the gap as the lens portion 12 as shown by the arrow to form a plate having flat surfaces on both sides. It is made by integrally molding into a shape.

As a result, the lamp lens 10 has a surface (lens portion 11).
Side) is orange, and the original orange color is regularly scattered in a matrix when the lamp is lit, and the surrounding area is stepped 11
Yellow-orange is surrounded in a ring shape corresponding to the shapes of b and 12b, and a brighter yellow-orange pattern corresponding to the shape of the top 12a is formed around the ring. Therefore, due to the stippling effect in which the lightness and the hue are changed in two steps, the orange color looks vivid and the aesthetic appearance is improved.

Incidentally, in the above-mentioned embodiment, the lamp lens 10 is a lighting device,
When used for interior furniture or the like, it may be possible to make the exposed side of the lens portion 12 the surface. When the structure of the lamp lens 10 is adopted as the stop signal, the lens portion 11 is made red and the lens portion 12 is made another brighter hue such as orange.

[Effect of device]

As described above, according to the present invention, different hues having different brightnesses that change stepwise in two or more steps are formed on the lamp lens surface with a simple structure.
By arranging in a matrix form in the vertical and horizontal directions, for example, it is possible to realize a lamp lens having a high design effect such that the lens color itself can be clearly seen.
