Definitions

  • the present invention relates to an automotive lamp and, in particular, a structure of a lamp installed at a rear part of a vehicle.
  • DRL daylight running lamp
  • clearance lamp is used for the purpose of having the drivers of other vehicles and the pedestrians visually recognize the presence of a driver's own vehicle in an accurate and clear manner.
  • Such a lamp as DRL or clearance lamp is often installed not only at a front part of the vehicle but also at a rear part thereof. In order to improve the safety, it is required that the visibility of this type of lamps be enhanced.
  • a vehicular indicator lamp described as follows is disclosed in Patent Document 1.
  • This vehicular indicator lamp has fan-shaped reflection regions where a group of linearly-arranged bright parts, in which the size of each bright part is gradually increased radially outward, are generated and where another group of linearly-arranged small bright parts, in which these small bright parts having approximately equal size are arranged in a chain-like form, are generated.
  • This lamp having such the reflection regions causes a glittering and lively-varied effect when the lamp is lit.
  • following vehicle also
  • Patent Document 1 Japanese Patent Application Publication No. 2006-216455 .
  • a white transparent cover is generally mounted to the daytime running lamp or clearance lamp. Since such a white transparent cover hardly absorbs the sunlight, the sunlight enters the lamp and is reflected by a reflector or the like when the morning or evening sunlight hits the lamp. Thus there is problem that it is not easy for the driver of the following vehicle to recognize whether the light source of the lamp itself is lit or not. For this reason, new regulations may possibly be formulated in the near future. Here, the new regulations may so regulate that a predetermined difference in the brightness between when the light source is turned off and when it is turned on can be ensured when the automotive lamp is irradiated with the artificial sunlight.
  • the present invention has been made in view of the foregoing circumstances, and a purpose thereof is to provide a technology that improves the visibility for a driver of the following vehicle as to a lighting state of the light source of a lamp, when the sunlight hits the lamp installed at a rear part of the vehicle.
  • an automotive lamp includes: a light source; a transparent cover, placed in front of the light source, through which light emitted from the light source passes; and a light shielding structure that reduces an amount of irradiated light, which reaches the light source, in a light entering the automotive lamp through the transparent cover from above at a predetermined angle relative to a horizontal line.
  • the light shielding structure reduces an amount of irradiated light reaching the light source. Provision of the light shielding structure eliminates the overlapping of the sunlight reflected inside the lamp with the light emitted from the light sources. This allows the driver of the following vehicle to easily determine if the light sources are lit up.
  • the present invention improves the visibility for a driver of the following vehicle as to a lighting state of the light source of a lamp, when the sunlight hits the lamp installed at a rear part of the vehicle.
  • a first exemplary embodiment of the present invention is characterized by a feature wherein a light shielding structure is provided in a lamp and whereby the visibility of the lamp when the lamp is lit is improved.
  • the light shielding structure is a structure that reduces an amount of irradiated light, which has reached a light source of the lamp, in the sunlight entering the lamp through a transparent cover from above at a predetermined angle relative to a horizontal line.
  • FIG. 1 is a schematically illustrated cross-sectional view of an automotive lamp 10, according to a first exemplary embodiment, cut along a vertical plane including an optical axis.
  • the automotive lamp 10 is installed at a rear part of a vehicle, and the leftward direction (part) in FIG. 1 corresponds to a rearward or rear part of the vehicle.
  • the automotive lamp 10 is a daytime running lamp (DRL) or a clearance lamp (CLL), for instance.
  • DRL daytime running lamp
  • CLL clearance lamp
  • a lamp chamber 15 is formed by a lamp body 13, having an opening in a direction toward the rear of the vehicle, and a transparent cover 12, made of white transparent resin, which is so disposed as to cover the opening.
  • a plurality of light sources 16 mounted on a substrate 14 are provided inside the lamp chamber 15.
  • the light sources 16 are each constituted by a semiconductor light-emitting element such as a light emitting diode (LED).
  • An inner lens 18 made of resin having translucency is placed adjacent to the substrate 14.
  • Lens portions 19 for controlling the distribution of light emitted from the light sources 16 are formed in partial areas of the inner lens 18; the partial areas thereof face the light emission surfaces of the light sources 16, respectively.
  • the light emitted from the light sources 16, which has been subjected to the light distribution control performed by the lens portions 19, transmits the transparent cover 12 and is irradiated in a rearward area of the vehicle.
  • a plurality of extensions 2, 4 and 6 having non-translucency are disposed between the transparent cover 12 and the inner lens 18.
  • the extensions 2, 4 and 6 have a role to block the light entering the lamp from above at a predetermined angle ⁇ relative to the horizontal line so that this light entering the lamp does not directly hit the light sources 16.
  • the light entering the lamp from above at the predetermined angle ⁇ relative thereto is indicated by solid arrows in FIG. 1 .
  • the angle ⁇ is set according to the angle of the morning or evening sunlight formed relative to the horizontal line, when it is especially hard to see the emission of light from the light sources in the automotive lamps, due to the reflected light of sun, for instance.
  • the angle ⁇ is preferably set at 10 to 15 degrees.
  • the extensions 2, 4 and 6 have extending sections 2a, 4a and 6a, respectively, which extend from near the inner lens 18 toward the transparent cover 12 up to the positions where the extensions 2, 4 and 6 intersect respectively with lines extending upward from the light sources 16 by the predetermined angle ⁇ .

  • the extensions 2, 4 and 6 that extend between the transparent cover 12 and the inner lens 18 are provided in the automotive lamp 10 according to the first exemplary embodiment. Provision of the extensions 2, 4 and 6 therebetween can reduce the amount of irradiated light, which has reached near the light sources 16, in the sunlight entering the lamp through the transparent cover from above at the predetermined angle relative to the horizontal line. Thus, the sunlight reflected by the inner lens and the like does not overlap with the light emitted from the light sources 16.

Applying the coating material to the side surfaces thereof reduces the amount of irradiated light, which has reached near the light sources 16, in the sunlight entering the lamp through the transparent cover from above at a predetermined angle relative to the horizontal line. This therefore reduces an area where the sunlight reflected by the inner lens and the like and the light emitted from the light sources overlap with each other. Hence, the driver of the following vehicle easily determines the lighting state of the light sources.
  • FIG. 3 is a schematically illustrated cross-sectional view of an automotive lamp 30, according to a third exemplary embodiment, cut along a vertical plane including an optical axis.
  • extensions 32, 34 and 36 are disposed between the transparent cover 12 and the inner lens 18, similarly to the first exemplary embodiment.
  • the extensions 32, 34 and 36 do not extend toward the transparent cover 12, and merely form openings near the line of intersections intersecting with the optical axes Ax that pass through the respective light sources 16 and extend in an approximately horizontal direction.
  • the extensions 32, 34 and 36 can reduce the amount of irradiated light, which has reached the light sources 16, in the sunlight entering the lamp through the transparent cover from above at a predetermined angle relative to the horizontal line. This therefore reduces an area where the sunlight reflected by the inner lens and the like and the light emitted from the light sources overlap with each other. Hence, the driver of the following vehicle easily determines the lighting state of the light sources.
