<p>PURPOSE:To minimize the variation of light quantity caused depending on illuminating direction by providing a plurality of light emitting bodies in a bulb having a lens and a reflecting mirror, and turning each light emitting body to the center part of the lens. CONSTITUTION:This lamp 1 has a bulb B consisting of a lens 1 and a reflecting mirror 2, and light emitting bodies 3a-3c in the bulb B. A switch interlocked toa steering device is changed over to selectively emit a light from the light emitting bodies 3a-3c, whereby by illuminating direction can be switched. In this case, each light emitting body 3a-3c is turned to the center part of the lens 1. Each light emitting body 3a-3c is formed of a bulb. Since each light emitting body 3a-3c has such a constitution, dispersion of light is prevented, and the variation of light quantity caused depending on illuminating direction can be minimized.</p> |
