Description

[Detailed Description of the Invention] The present invention relates to a so-called reflective type diffused light in which a large number of reflectors are arranged side by side at appropriate intervals on a stand, and the light from a rotating light is reflected and projected in the front and rear directions. This is an improved idea for a diffused light in which the reflected light can be easily confirmed in the front, back, and diagonal directions without any interruption of light.

The inventor first installed a revolving light 2 at one end of the table 1 as shown in the third diagram, and installed several reflective plates 3.4.5 on the front and rear sides of the revolving light 2. .3', 4'.

5' are arranged at appropriate intervals at a constant inclination angle with respect to the rotating light 2, and the front and rear reflecting plates 3, 4°3',
Spaces 6, 6' are provided between 4', and the spaces 6, 6' are used as light passages to greatly expand the effective area of reflection of the light from the rotating light 2 in the longitudinal direction of the vessel. We have independently developed a reflective type diffused lamp that emits reflected light.This type of diffused lamp, shown in Figures 1 and 2, has a larger reflective effective area and a narrower opening compared to conventional diffused lamps. It expanded to +Ro+Ha, proving that its effect was extremely large.

However, the reflection plate 3.4. 5.3', 4', 5
The direction of reflection according to ' is carried out only in the front-back direction due to the relationship of the reflector, and for example, reflection is not performed in the direction of arrow A, and the light is projected in an oblique direction other than the front-back direction. It turned out that it was not possible.

In view of this problem, the present invention has been developed with the front and rear reflecting plates 3, 4.
The space 6, 6' between 3' and 4' is effectively used, and a light transmitting prism 7 is disposed in the space 6, 6' as shown in the fourth figure, and the multiplexing is performed by the action of the light transmitting prism 7. The main purpose of this system is to perform diffused light projection by expanding the reflected local light range not only in the front and rear of the vessel but also in diagonal directions.

Hereinafter, detailed explanation will be given with reference to FIG. 4 illustrating an embodiment of the present invention. 1 is a table; 2 is a rotating light; 3. 4. Reference numeral 5 denotes a reflector plate, which is disposed at a predetermined angle of inclination with respect to the rotating light 2 at an appropriate interval on the front side of the table 1. 4. On the opposite side of the back of the lamp 5, that is, at the rear, several reflection plates 3', 4', and 5' are arranged at appropriate intervals and at a constant angle of inclination with respect to the rotating light 2, in the same manner as described above. ing.

Further, a space 6.6' is formed between the front and rear reflecting plates 3.3' and 4.4' to serve as a light path, and a colorless transparent prism is formed at a predetermined inclination angle in the space 6,6'. Place 7.

The present invention has the above-mentioned structure, and the light from the rotating light 2 is moved back and forth by the front reflector 3°4.5 and the rear reflectors 3', 4', and 5' as it rotates. Light is projected through the front and rear reflectors 3.3'.

Since the spaces 6 and 6' are provided between the spaces 6 and 4', the effective area of reflection by the reflected light projection, i. It may be possible to eliminate it completely.

In particular, the present invention utilizes the spaces 6 and 6' to
By disposing the light-transmitting prism 7 in the space 6, 6', the light from the rotating lamp 2 passing through the spaces 6, 6' is reflected by the light-transmitting prism 7 as shown in Figure 5, and this is reflected in the direction of arrow B. That is, by the outward reflection of light from between each reflection plate 3.4.5° 3', 4', and 5' and the reflection destination action of each surface by the light-transmitting prism 7, the end reflection plate 5, 5' The reflected light is reflected and projected outward in the direction of arrow C.

Therefore, the reflection area is expanded without causing any faults or bright/dark zones in the projection, not to mention the non-light projection parts in the effective reflection area (a) and (b), and the intense reflection is projected over the entire front and rear oblique directions. Light is obtained, and the emitted light is further diffusely reflected between both reflecting plates due to the action of the light-transmitting prism 7, so that a more effective light scattering state can be expected.

Moreover, the light-transmitting prism 7 has front and rear reflecting plates 3°3'...
...Since it is placed in the space 6, 6' formed between the transparent prisms 7, the shape of the transparent prism 7 cannot be seen from the outside, and the design is excellent and the transparent prism 7 is By arranging colored plates with different colors on each side of the optical prism 7, or arranging various transparent plates at appropriate angles in place of the transparent prism 7, a unique colored light projection can be obtained, which can be used for decoration,
Its uses can be said to be extremely wide-ranging, including advertising lights.
