Abstract
In vehicle lamps from the prior art using LED lamps as a light source, the insufficiency of quantity of light obtainable from the light source has made it difficult for headlamps and other illuminating lamps to be realized. A vehicle lamp 1 according to the present invention comprises a plurality of light sources 2 realized using LED arrays 22 disposing at least one or more LED chips 22a in a single row and reflecting surfaces 3 combined in a one-to-one correspondence with the respective light sources 2 and forming a prescribed light distribution pattern in each combination, characterized in that 2 to 12 sets in combinations of a single one of the light source and a single one of the reflecting surface are used, and an overall light distribution pattern is formed by combining the light distribution patterns formed by each set; and by realizing light sources using LED chips, a remarkable number of LEDs can be positioned in the vehicle lamp, thus resolving the problem of insufficient quantity of light, and in addition, enabling the formation of light distribution patterns with no associated problems.
