A headlight with a modular projection module for enhancing illumination intensity, comprising:
- a base having a connection portion formed on and protruding obliquely downwards and rearwards from a middle portion of the base;
- a lighting module mounted on a top of the connection portion of the base;
- a support frame mounted on a front portion of the base and having an opening formed through the support frame;
- a reflective cover mounted on the top of the connection portion of the base with a front portion of the reflective cover mounted through the opening of the support frame, and having a first reflective surface concavely formed on an inner wall of the reflective cover and facing the lighting module;
- a lens assembly mounted on a front portion of the support frame and having a center line centrally passing through the lens assembly, wherein the center line is an optical axis of the lens and the lighting module is located below the center line of the lens assembly;
- and
- a light-shielding member mounted between the lens assembly and the support frame and having:
- a blocking wall formed on and protruding upwards from a top edge portion of a right half part of the light-shielding member, and located above the center line;
- a blocking ear formed on and horizontally protruding rearwards from a portion of a rear surface of the blocking wall which is adjacent to a left end of the blocking wall, and located above the center line;
- and
- a reflective block formed on and obliquely protruding downwards and rearwards from the rear surface of the light-shielding member, located below the blocking ear, and having a second reflective surface concavely formed on a rear portion of the reflective block and facing the first reflective surface of the reflective cover;
- wherein a vertical plane and a horizontal plane perpendicularly intersect in the center line, light emitted from the lighting module is reflected by the reflective cover, is partially blocked and partially reflected by the light-shielding member, and passes through the lens assembly to generate an illumination pattern associated with lower beam for right hand traffic, wherein
- the illumination pattern includes:
- a left half pattern and a right half pattern located below the horizontal plane and divided by the vertical plane, wherein the left half pattern is lower than the right half pattern;
- a passing-beam dimming zone located in the left half pattern, and defined to be an area 0.86 degrees below the horizontal plane and 3.5 degrees to the left of the vertical plane, wherein a part of light emitted from the lighting module and irradiating to the blocking ear is blocked by the blocking ear of the light-shielding member to prevent the part of light from further irradiating to the lens assembly and cause a reduced luminous intensity at the passing-beam dimming zone;
- a brightened region stretching across the vertical plane and divided by the vertical plane to have:
- a left part located on the left of the vertical plane, extending downwards from a top edge portion of the left half pattern and leftwards from the vertical plane, and spaced apart from the passing-beam dimming zone by a gap;
- and
- a right part of the brightened region extending rightwards from the vertical plane with a left top portion thereof coinciding to a left top portion of the right half pattern of the illumination pattern;
- wherein a part of light emitted from the lighting module and irradiating to the second reflective surface of the reflective block is sequentially reflected by the second reflective surface and the first reflective surface of the reflective cover and the reflected light further irradiates to pass through the lens to cause an increased luminous intensity at the brightened region.
