本発明は発光ダイオードを光源として利用した車輛用灯
具に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle lamp using a light emitting diode as a light source.
近年、半導体技術の発達により輝度の高い発光ダイオー
ドが開発され、安価に入手できるようになったことから
、車輛用灯具１例えば方向指示灯。In recent years, with the development of semiconductor technology, high-brightness light emitting diodes have been developed and can be obtained at low cost.
後退灯２尾灯などの光源として電球の代りに使用される
に至っている（例実開昭５７−１１２４０５ 。It has come to be used instead of a light bulb as a light source for two rear lights, etc. (Example: 112405/1983).
実開昭５８−３４３０１）、発光ダイオードは電球と異
なりフィラメントを有さないため、半永久的な寿命を有
し、また電球を使用した灯具は断線時に交換できるよう
な構造にしなければならないため、灯具自体およびその
取付位置を制限されるが、発光ダイオードは交換を必要
とせず灯具自体および取付位置に対する制約が少ない。Unlike a light bulb, a light emitting diode does not have a filament, so it has a semi-permanent lifespan, and a light fixture using a light bulb must be constructed so that it can be replaced in the event of a break, so it Although there are restrictions on the lamp itself and its mounting position, light emitting diodes do not require replacement and there are fewer restrictions on the lamp itself and its mounting position.
通常の灯具は電球の長さおよび反射鏡の奥行分だけ奥行
寸法が大きくなり車体内に埋込むような形状になるが、
発光ダイオードを使用した灯具はダイオード自体が極め
て小さくまた反射鏡を必要としないため薄型化でき、灯
具の取付けが容易である０発光ダイオードは電球に比べ
て発熱が著しく少なく発光効率が良いなど多くの優れた
特徴を備え、今後の灯具の方向を示すものと云える。Normal light fixtures have a depth dimension that increases by the length of the bulb and the depth of the reflector, and are shaped to be embedded inside the vehicle body.
Lighting equipment using light-emitting diodes can be made thinner because the diode itself is extremely small and does not require a reflector, and the lighting equipment is easy to install.0 Light-emitting diodes have many advantages, such as significantly less heat generation than light bulbs and high luminous efficiency. It has excellent features and can be said to indicate the direction of future lighting equipment.

う点で問題があり、より明るい照明が得られない。By the way, I? Due to design requirements, it has been proposed for recent lighting equipment that the front lens itself has a light transmitting part and a light non-transmitting part to vary the illumination. If the corresponding diode is provided, only the light of the diode will pass through the light transmitting part, and the light of the light emitting diode in i-contact will not pass through.Therefore, there is a problem in terms of effective use of light, and brighter illumination cannot be obtained. do not have.
本発明は上述したような点に鑑みてなされたもので、光

光体で形成した６士ものである。In the vehicle lamp according to the present invention, the portion of the front lens corresponding to the light emitting diode is a light transmitting portion, the other portion is covered with a light shielding film, and the holding member for holding the light emitting diode is formed of a light guide. It is a professional thing.
本発明においては、保持部材を導光体で形成したので、

Friend, the front lens 30 is integrally provided with the bent portion 2A21Fl of the back cover 2 and the bent portion 3A bent along the side of the vehicle body. It consists of By masking the surface of the front lens 3 with a light-shielding film 9 of the same color as the case body, it has a large number of light transmitting parts 10 provided at predetermined intervals in the vertical and horizontal directions. , The remaining 1 minute of the seedling constitutes a light-impermeable part by blocking light [q 9, and the inner surface is densely formed with a group of small lenses consisting of multi-V convex lenses 11. The holding member 5 is for holding the light emitting diode 6 and guiding the light emitted from the diode 6 further to prevent light loss. is fixed to the inner surface of the protrusion of the front lens 3 by a set screw 12. Further, a large number of small holes 13 are formed through the holding member 5 in correspondence with each of the light transmitting parts 10 of the front lens 3, and a red light emitting diode 6 is inserted into each of these small holes 13. ing.

薄型化できる利点を有する。Lead wire 14 of each light emitting diode 6. ．． 14b is a circuit board 7 interposed between the holding member 5 and the back cover 2.
The electrical circuits K[j of the board 7 are connected by being inserted into the lead wire insertion holes of the board 7 and soldering by dip soldering. Although it is possible to use a general printed circuit board made of glass epoxy resin or Bakelite as the circuit board 7, it is possible to use a printed circuit board made of general glass epoxy resin or Bakelite. It is preferable to use a flexible printed circuit board.
By doing so, the flexibility of the board itself can be used to absorb errors in the assembly of the light emitting diode 6, making it easier to insert it into the small hole 13, and at the same time making the light emitting diode 6 smaller due to the restoring force generated by the bending. Since it is pressed against the circumferential surface of the hole 13, it prevents the diode from wobbling, and since it is thinner than a general substrate, it has the advantage that the thickness (depth dimension) of the lamp can be further reduced.

るため、暗部が生じることはない。Here, when focusing on a certain light emitting diode 6, a part of the light a1 passes through the front lens 3 and is directly emitted to the outside from the light transmitting section 10a corresponding to the diode, and the other part a1 of the light as , a8 travels through the holding member 5 while reflecting, and light transmits ai0b corresponding to the adjacent light emitting diode.
, 10c to the outside. Furthermore, the lights bl and cl from the adjacent light emitting diodes 6 are guided to the light transmitting portion 10a while being reflected within the holding member 5 in the same manner as described above. Therefore, the light from the light emitting diode 6 is effectively used with little loss and brightly illuminates each light transmitting section 10. Furthermore, even when looking into the light chamber 4 through the light transmitting part 10, the light emitting diode 60 can be seen.
Since not only the surrounding area but also the entire holding member 5 is brightly illuminated, dark areas do not occur.

ある。FIG. 3 is an enlarged sectional view of a main part showing another embodiment of the present invention. In this embodiment, a reflecting part 20 made of a spherical surface whose focal point is the light emitting source of a light emitting diode, for example, is provided at the opening on the front lens 3 side of each small hole 13 formed in the holding member 5. Reflecting the light emitted from 6,
The light is effectively and effectively guided to the light transmitting section 10.

を有効利用でき、照明効果を向上させることができる。As explained above, in the vehicle lamp according to the present invention, since the holding member that holds a large number of light emitting diodes is formed of a four-light body, a part of the light is guided farther and corresponds to the corresponding diode on the front lens. Since parts other than the parts are illuminated, light can be used effectively and the lighting effect can be improved.
