Vehicle lamp control system

A vehicle lamp control system comprising:

• a light source unit in which a plurality of semiconductor light emitting elements are arranged in a predetermined direction and are connected in parallel with each other, the plurality of light emitting elements including a centermost light emitting element, respective outermost light emitting elements, and intermediate light emitting elements arranged between the centermost light emitting element and the respective outermost light emitting elements;
• an electric current setting unit that can set electric current values for each of the plurality of semiconductor light emitting elements individually;
• and
• a control unit that controls individually the turning on and off of the plurality of semiconductor light emitting elements based on the electric current distributions set by the electric current setting unit,
• wherein the electric current setting unit can set a first electric current distribution in which electric current values for the plurality of semiconductor light emitting elements to form a predetermined light distribution pattern ahead of a lamp are set individually for the plurality of semiconductor light emitting elements and a second electric current distribution in which electric current values are set individually for at least a portion of the plurality of semiconductor light emitting elements and whose mean electric current value is smaller than that of the first electric current distribution,
• wherein when the light source unit is turned off from a state in which a light distribution pattern is formed by using the first electric current distribution, the control unit performs a control in which all of the plurality of semiconductor light emitting elements are turned off after the plurality of semiconductor light emitting elements are turned on based on the second electric current distribution, and
• in the first electric current distribution the electric current values for the plurality of semiconductor light emitting elements are set individually such that each respective electric current value of the intermediate light emitting elements gradually decreases from the centermost light emitting element, being set at a highest electric current value, to the respective outermost light emitting elements, being set at a lowest electric current value.
