。This reflection II (4) is formed into a mirror-finish medium-color light selection screen to reflect the light, and is further provided with a light-emitting surface (5) on the front side. Therefore, this illumination surface (5) has direct light from the LIDO light source! I light and reflection N(4) once reflected t7
In order to effectively reach each other, a WLK material is used for the illumination surface to diffuse the light. Il
/#, when trying to display a flat display, the illumination surface (5) which is the display part should be uniformly 1kl, and in order to eliminate unevenness of light, the light source and the illumination surface ω ), and by using one or more LIID balances to diffuse light using a reflection effect.

1! If you don't let go, Sue etc. tkTI! 4. I can't maintain my mood.
そのため1表示灯としてのケースの奥行が長くなる。■
奥行が長くなるため光が減衰する。Therefore, the depth of the case for one indicator light becomes long. ■
As the depth increases, the light attenuates.
■奥行を短くしてLIDIDランプて拡散形を用いると
、照光面の中央部は明るく表るが周囲は暗く全体として
照るさが不足する6等の欠点がありた。■If the depth is shortened and a diffused type LIDID lamp is used, the central part of the illumination surface appears bright, but the surrounding area is dark and the overall illumination is insufficient, which has the disadvantage of 6th grade.

のである。A part of the light emitted from the LIID chip O in the direction opposite to the illumination surface exits from the arcuate surface (b) on the back side of the transparent resin body, passes through the arcuate surface (b) at the intersection, and reaches the reflective surface. It is reflected by (2) and diffuses towards the illumination area (shown by the solid line in Figure 3).Also, a part of the light emitted from the chip O (LII) is reflected inside the transparent ATM body (b). The light from LIiD chip 0 is reflected directly from the arcuate surface (toward), and there is also a 5% directivity toward the illumination surface (shown by the broken line in Figure 3). ! Don't hit it,
All indirect light reaches. Therefore, even though the distance from the light source is short at the same illumination surface, there is no glaring feeling, a knotty feeling is given, and there is no unevenness in the light. Furthermore, since it utilizes a reflection effect other than that of a lamp, it can be used by being attached to a conventional lighting device.
