本発明は光量損失が少なくて有効発光面積が大きい車両
用ランプに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicular lamp with a small loss of light quantity and a large effective light emitting area.

増さなければならないという問題がおる。(Prior Art) Conventionally, incandescent lamps that emit white light and colored lenses that emit a specified light distribution color have been used for vehicle rear combination lamps, high-mounted stop lamps, and the like. If you want to put letters or patterns on the lens surface of this type of lamp, you can paste opaque letters or patterns on the lens surface, or conversely, form a colorless part with low transmittance on a part of the lens. (Nissan Motor Co., Ltd., Service Bulletin, Nirasan Fair Redisette, September 1980 issue, page V-8), but when the lamp is lit, light does not pass through the text and pattern. In those parts, the light transmittance is low, so there is a loss in the amount of light. Therefore, in order to expand the effective light emitting area of the lamp by that amount, there is a problem that the lamp itself must be made larger or the amount of light emitted from the lamp must be increased.

字や模様として設だ。(Object and Structure of the Invention) The present invention has been made in view of the above points, and an object of the present invention is to provide a vehicle lamp with a small loss of light quantity and a large effective light emitting area. On the surface of the achromatic lens of a vehicle lamp or a light emitting source made up of a group of LECs, a colored transparent body with a similar color to the emitted light color of the light source is placed as letters or patterns.
(実施例) 以下本発明を図面に基づいて説明する。(Example) The present invention will be explained below based on the drawings.
第1図および第2図は本発明による車両用ランプの一実
施例を示しており、第1図はランプの正面図、第2図は
第1図のA−A断面図である。FIGS. 1 and 2 show an embodiment of a vehicle lamp according to the present invention, with FIG. 1 being a front view of the lamp and FIG. 2 being a sectional view taken along line A-A in FIG.
ランプはハウジング1とレンズ2とを接着剤などで接合
し、内部にはハウジング1に固定されてプリント板3が
設けられ、このプリント板3に特定波長(たとえば赤色
)の光を発光する多数のしED4が密に配列されている
。The lamp is made by joining a housing 1 and a lens 2 with adhesive or the like, and has a printed board 3 fixed to the housing 1 inside, and a large number of lights that emit light of a specific wavelength (for example, red) on this printed board 3. The ED4s are arranged densely.
一方、レンズ2は無色透明体で、その一部にLED4の
発光波長(たとえば赤色)に近似する着色透明体でたと
えばABCのような模様文字部5が形成されている。こ
のレンズ2の着色部と無着色部とは逆でおってもよい。On the other hand, the lens 2 is a colorless transparent body, and a patterned character portion 5, such as ABC, is formed on a part of the lens 2, which is a colored transparent body that approximates the emission wavelength (for example, red) of the LED 4. The colored portion and uncolored portion of this lens 2 may be reversed.

塗装などにより薄膜として設けてもよい。The pattern character portion 5 made of a colored transparent material may be provided by integral molding on the lens surface as shown in FIG. 3 (A), or may be provided by integral molding on the back surface of the lens as shown in FIG. Alternatively, it may be provided as a thin film by hot stamping, painting, etc., as shown in FIG.

字部5は肉眼ではほとんど見えないのでデザイン上問題
にはならない。According to the lamp configured in this way, when the lamp is turned off, the pattern character part 5 is recognized as a colored color (red in this case), but when the LED 4 is energized when the lamp is turned on, a specific wavelength (this color) is recognized from the LED 4. Since the light (in case of red) passes through the pattern character part 5, which is a colored transparent body, and exits to the outside, there is no loss of light quantity.Moreover, since the pattern character part 5 has the same color as the emitted light from the LED 4, the lens surface is uniform. is emitted. At this time, the pattern character portion 5 is almost invisible to the naked eye, so it does not pose a problem in terms of design.

を設けた点である。This embodiment also has a housing 1 and a lens 2 joined together, and a large number of LEDs 4 arranged regularly on a printed board 3 fixed to the housing 1.The difference from the previous embodiment is that the lens 2 is colorless and transparent over its entire surface or is thin. colored,
Several LEDs 4 forming a letter or pattern
A colored transparent body 4a with the same color as the LED light emitting color is attached to the chip part.
The point is that
このようにすれば、ランプ消灯時にはレンズ2を通して
模様文字が着色された色で認識されるが、ランプ点灯時
にはLED4からの光が模様文字部を構成する着色透明
体4aを透過するので光量損失がなくしかもLED4の
発光色と着色透明体4aの着色とが同系色でおるのでラ
ンプ全面が均一に発光する。In this way, when the lamp is off, the pattern letters are recognized as colored through the lens 2, but when the lamp is on, the light from the LED 4 passes through the colored transparent body 4a that constitutes the pattern text, so there is no loss in the amount of light. Moreover, since the color of the light emitted by the LED 4 and the color of the colored transparent body 4a are similar in color, the entire surface of the lamp emits light uniformly.
上記2つの実施例においては模様文字部を着色したが、
逆にレンズまたは発光体の模様文学部以外の部分を着色
してもよいことはもちろんである。In the above two embodiments, the pattern text portion was colored, but
On the other hand, it is of course possible to color the lens or the portion of the light emitter other than the pattern part.
