<p>A direct emanating area (18) for emanating light from a light-emitting device (12) directly outside and a total-reflection area (19) for total reflection of light from the light-emitting device (12) are provided at the front interface of a molding resin (13) encapsulating the light-emitting device (12). The direct emanating area (18) has a shape like a convex lens. A light reflecting part (20) having a shape like a concave mirror is provided at the back of the molding resin (13). Part of the light emitted from the light-emitting device (12) undergoes a lens action when passing through the direct emanating area (18) and emanates forward. Another part of the light emitted from the light-emitting device (12) undergoes total reflection at the total reflection area (19), is reflected from the light reflecting part (20), and emanated forward from the total reflection area (19).</p> |
