PURPOSE:To reduce directivity by fixing a fluorescent molded object so as to keep a specified distance from a diode chip, and forming an infrared rays scattering body between the diode chip and the fluorescent molded object. CONSTITUTION:A fluorescent molded object 2 which dispersedly contains conversion phosphor is fixed so as to keep a specified distance from a diode chip 1. Between the diode chip 1 and the fluorescent molded object 2, an infrared rays scattering body 9 is formed, whose upper surface is desirably constituted as a Fresnel concave lens or a satin pattern or concentric circular trenches. An infrared light emitting body 9 is so constituted that the upper surface of the infrared rays scattering body 9 is positioned just above the diode chip 1. The infrared light emitting body 9 is inserted into the fluorescent molded body 2, and the outer periphery of the molded body 2 is packaged with transparent resin mold 7. Thus conversion light emitting diodes 1-3 are manufactured, respectively. Thereby the directivity is reduced, and clear indication can be obtained. |
