Abstract
A vehicle lamp can be designed to prevent troubles ascribable to handling during manufacturing, and to be capable of light distribution over a wide range while suppressing uneven light distribution in each individual lamp and suppressing light distribution variations between separate individual lamps, even at low cost. LED mounting substrates having a plurality of LEDs mounted thereon can be attached to an inner lens bracket made of a light-transmitting resin material so that the light sources can be accommodated in respective bracket portions of the inner lens bracket, having openings. The inner lens bracket to which the LED mounting substrates are attached can further be attached to the inner panel so that the bracket portions accommodating the LEDs protrude from the bracket portion insertion holes of the inner panel.
Claims24
A vehicle lamp comprising:
- a front lens;
- a housing configured to form a lamp chamber together with the front lens;
- and
- a lamp unit supported inside the lamp chamber, the lamp unit including a plurality of light sources, a plurality of substrates having the plurality of light sources mounted thereon, and an inner lens bracket located adjacent and configured to support the substrates, the inner lens bracket being made of a light-transmitting resin material, the inner lens bracket including a plurality of bracket portions configured to surround respective ones of the plurality of light sources, wherein ends of the bracket portions opposite from a base portion of the inner lens bracket each have a total reflecting surface configured to reflect light emitted from a corresponding one of the light sources.
A vehicle lamp comprising:
- a front lens;
- a housing configured to form a lamp chamber with the front lens;
- a plurality of substrates located in the lamp chamber;
- a plurality of light sources electrically connected to the plurality of substrates, each of the plurality of light sources having an optical axis along which light is directed when electricity is applied to the light sources;
- and
- an inner lens bracket located adjacent the substrates, the inner lens bracket made of a light-transmitting resin material and including a plurality of bracket portions configured to surround a respective one of the light sources, the bracket portions including a first end, a second end, a first side, and a second side, the first side of the bracket portion located opposite to the second side of the bracket portion when viewed along the optical axis of a respective light source, the first side of the bracket portion being shaped differently in cross section than the second side of the bracket portion when viewed in a direction orthogonal to the optical axis of the respective light source, and wherein the shape of the first side of the bracket portion is configured to cause light to transmit at a first angle with respect to the optical axis of the respective light source, and the shape of the second side of the bracket portion is configured to cause light to transmit at a second angle with respect to the optical axis of the respective light source, an absolute value of the second angle being different from an absolute value of the first angle.
