Abstract

PURPOSE:To enable to emit an indirect beam of light giving a soft feeling from the illuminating surface of a housing by a method wherein the point of a pair of lead frames protruding outward is bent, an LED chip is adhered to the lower surface of said lead frames, a molding is performed on this part alone using transparent resin, and the light-emitting surface of the chip on the LED lamp which is obtained as above is positioned on the parabolic side of the housing. CONSTITUTION:Of a pair of lead frames 11 and 12 conisting of a base side and a plus side, the point of the frame 11 is bent at a right angle and the LED chip 14, which was turned its back to the front side, is adhered to the lower surface of the mounting part 13 of said frame 11. Also, a bent engaging piece 15 is provided at the point of the frame 12, and the lower surfaces of the engaging piece 15 and the chip 14 are connected using a bonding wire 16. Then, the chip 14 part is going to be soldered using transparent resin material 17, and at this time, the back side of the chip 14 is to be formed, without fail, into an arc- shaped surface 18 such as parabolic and the like. Subsequently, the arc-shaped surface 18 of the LED lamp 20 is arranged facing the reflecting surface 21 which was provided on the housing 22, and a beam of light is irradiated from the side of the illuminating plate 24 of the housing.

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.

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.

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.
