ABSTRACT:
An automotive headlight having a hood to shade harmful beams of light as far as possible, in which a lamp bulb is provided at the focus of the reflector and a diffuser lens is provided in front of the reflector. The hood is provided in such a manner that the light which is emitted from the filament and passes by the base of the glass tube constituting the lamp bulb is shaded. In the first example, the harmful light which has passed by the base of the glass tube is shaded by the extension of the hood leg before it reaches the reflector. In the second example, the light is shaded by the front of the hood after reflection by the reflector.
