Abstract

PURPOSE: To improve transmission factor and thus to obtain a better luminous efficiency on LED chip by coating one principal surface of a thick substrate layer used for filter plate thinly with a mixture of light diffusing pigment and adhesive.
CONSTITUTION: A thick substrate layer 61 is used to rigidify a filter plate 6, a light diffusing adhesive layer 62 obtained through coating one principal surface of the layer 61 thinly with a mixture of light diffusing pigment and adhesive is provided, and a transparent surface protecting layer 64 is provided on the other surface with an adhesive 63. Then, a reflection member 4 having a base 2, a wiring pattern 3 and a reflection face 4a surrounding LED1, LED1 arranged on the pattern 3 is provided on the other part. Transmission factor is improved thereby to obtain a better luminous efficiency on LED chip.
