ＬＥＤＩの光を前方に屈折反射させるもので。BACKGROUND ART Conventionally, as a vehicle lamp of this type that uses both an incandescent bulb and an LED as a light source and has two different lamp functions, for example, a lamp disclosed in Japanese Utility Model Application Publication No. 61-6207 is known. This is a lamp that uses an incandescent light bulb as a light source, with an LED lens attached to a part of the front lens, and a printed circuit board with multiple LED chips placed on the back side of this lens. The main parts are shown in Fig. 8, and 1 is an LED arranged on a printed circuit board 2.
, 3 is a lens for LEDI, and a plurality of lens cuts 4 are formed on the inner surface of this lens 3 corresponding to each LED 1. The lens cut 4 is used to refract and reflect the LED light that enters the cut 4 forward.

導電パターン。It consists of a protrusion that is approximately a paraboloid of revolution, and there is an IJD on its tip surface.
A recessed portion 5 for accommodating the light beam I is provided, and a peripheral wall 5a and a bottom surface 5b of this recessed portion 5 constitute an incident surface of the light 7. The lens cut 4 is close to or in contact with the printed circuit board 2,
By making most of the light 7 emitted from LgDl enter the cut 4, light loss is reduced. In addition, 8 is a conductive pattern.

いう不都合がめった。[Problems to be solved by the invention] However, in such conventional vehicle lamps, the shape of the lens cut 4 is complicated and manufacturing is troublesome. Since sink marks are likely to occur in the corresponding areas, it is not possible to increase the light convergence of the lens cut 4, and therefore the amount of light emitted in front of the lens 3 is small, making it impossible to obtain a sufficient illumination effect. I was disappointed.

ので、事故の防止に効果大である。Since the light-emitting element has a lamp function different from that of an incandescent bulb, one lamp can be used for multiple purposes and the number of lamps can be reduced. In addition, the light emitted from the 9 light-emitting elements is condensed and diffused by the condensing lens of the inner lens and the diffusing lens of the outer lens, and then emitted to the outside, so there is less loss of light and the surface of the outer lens is It can provide bright and uniform illumination. Furthermore, the use of light-emitting elements allows the lamp body to be made thinner and smaller, increasing the degree of freedom in designing the lamp body and vehicle body. Furthermore, there is no need to worry about the light emitting element breaking, and the light will continue to shine even if the incandescent light bulb burns out, so it is highly effective in preventing accidents.
さらに、インナーレンズの集光レンズは略半球状に形成
されているので、該レンズの製作が簡単である。Furthermore, since the condenser lens of the inner lens is formed into a substantially hemispherical shape, the lens is easy to manufacture.
