DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a lighting fixture whose illumination light emitting surface has a square shape and is used as a headlamp for an automobile.

(Prior art) Round headlamps were the mainstream for automobile headlamps, but recently square headlamps have become popular.
: Sea urchins are turning. The square shape is simple; in other words, the top, bottom, left, and right sides of a round shape are cut out with flat surfaces so that it looks like a square when viewed from the front.

A headlamp has a part that emits light (bulb) and a parabolic shape.
It is made up of three parts: the A mirror and the front lens, but as shown in Fig. 9, if you take out the rectangular one with the square shape 2 inscribed in the outer circle from the round reflector 1, the cut out part △ ,B,C
The light emitted to ,D is no longer available and the lamp is dimmed.

In order to prevent this reduction in light intensity, square headlamps generally use a reflector 4 that is slightly larger than the conventional round reflector 3, as shown in FIG. After taking it out, the loss of light in the vertical direction is compensated for by light in the diagonally shaded areas in the left and right directions (light that did not need to be used with the round shape).

In addition, even with the same power consumption, a bright halogen bulb (light R is 3

By the way, as shown in Figure 11(a), square headlamps have an aspect ratio of about 1:1.4 to 1=2, but recently they have been used to reduce the air resistance of cars and increase fuel efficiency. Further thinning is required due to design requirements.

However, if the bulb is formed by cutting the top, bottom, left, and right sides of a round shape with flat surfaces, the thinner the bulb is, the more the light emitted from the bulb will escape in the vertical direction, as shown in Figures 11(b) and (C). The amount of light emitted increases, and for bulbs with the same power consumption, the minimum amount of light is inevitably reduced. Furthermore, improvements in the efficiency of halogen light bulbs have almost reached their limits, and making them thinner has become a difficult problem.

Some luxury car models have a system in which the headlights are folded down and stored in the bonnet when not in use, such as during the day, and the headlights are raised when driving at night. An increase in air resistance is unavoidable. Also, methods are being considered in which multiple small square headlamps are lined up to form a single-phase headlamp.
There are problems with maintenance, etc.

The above explanation assumes that the point light source is at the focal point of the parabolic reflector 11, but if the light source has a certain size, for example, 1φX5s+, the reflected light from the parabolic reflector 11 has some spread. In order to effectively utilize the light that spreads in the peripheral direction, the reflective surface of the first reflector 13 should be moved in a direction that does not block the light A from the cross-sectional area of the prismatic body ejih-f1mk, which is the optical path of the light B in FIG. It may be designed to be a little wider.

Note that in the case of automobile headlamps, it is necessary to prevent upward scattering of light. The causes of upward scattered light can be broadly classified into the following three points.

(1) Light that enters the lens directly from the light source without hitting the parabolic reflecting surface.

(2)放物面反射鏡や電球の歪みによるレンズ効果。(2) Lens effects due to distortion of parabolic reflectors and light bulbs.

In this respect, the present invention has the advantage that direct light is generated only in a very narrow range because the lens surface is narrow, and no special measures are required for item (1). In particular, if the lamp shown in Figure 1 is turned upside down and the lower surface is painted black or made transparent, almost no upward light will be scattered. When used in the state shown in FIG. 1, the illuminance of the road surface can be increased by making the upper surface a silver mirror surface.

As described above, according to the present invention, the parallel reflected light from the paraboloid of revolution reflector is divided, and both sides of the reflected light that passes through the first and second reflectors and directly reaches the front lens are equally distributed in parallel. Since it has a structure that reflects light in the same direction, it is possible to make it ultra-thin and also has high light utilization efficiency. Therefore, when used as an automobile headlamp, it is possible to realize a rectangular headlamp that is thin, has low energy consumption, and has low upward scattering.
