ABSTRACT:
An electric device includes flat acrylic lens, and a blue light emitting diode. The lens includes bottom face upon which light is incident from the diode; front face from which light is emergent; pair of side portions opposed to each other and inclined by a predetermined angle with respect to the front face and the bottom face; and back face arranged so that end portions of the pair of side can be connected, substantially making a right angle with the bottom face. The pair of side portions reflects the light sent from the bottom face in the direction of the front face. When the side portions are directed to the back face, an inclination angle of the side plate with respect to the bottom face portion gradually comes close to a right angle.
