As a result, the illumination intensity at this point can fall within the acceptable range.
- the groove 616 formed in the front surface of the upper end portion of the shade 6 extends in the horizontal direction, it becomes possible to make the light be scattered across a predetermined width in the horizontal direction.

- a recess portion 617c formed along the vertical direction extends to the upper end portion of a thicker portion 615c of a wall portion 612c so that the lights are scattered about.
- the inventors of the present invention found out by various experiments and the like that the illumination intensity at the point of B50L or B50R (different depending on whether the headlight is used for right-hand traffic or for left-hand traffic) may exceed an allowable range because the lights reflected inside the projector type headlight are further reflected by the front surface of the shade to pass through the lens.
- the present invention makes the lights reflected by the front surface of the shade be scattered about by the groove. By this, the lights reflected by the front surface of the shade become hard to arrive the point of B50L or B50R. Consequently, the illumination intensity at this point can fall within an acceptable range.
- the groove in the upper end portion of the front surface of the shade extends along the horizontal direction, it becomes possible to make the light be scattered across a predetermined width in the horizontal direction. In other words, by one groove, the lights to reach the point of B50L or B50R can be scattered about.
- the upper portion of the groove has the surface sloping down rearward, the lights going into the groove are easily reflected downward. Because the point of B50L or B50R is located at a position higher than a horizontal plane, the lights reflected by the surface downward do not reach the point of B50L or B50R naturally. In other words, since the upper portion of the groove has the surface sloping down rearward, it becomes possible to further reduce the illumination intensity at the point of B50L or B50R.

FIG. 1 is a front view showing a whole configuration of a projector type headlight according to the present embodiment,FIG. 2 is an exploded perspective view showing a skeleton framework of the projector type headlight, andFIG. 3 is a cross-section view schematically showing a cross-section shape viewed from cutting-plane line III-III inFig. 1 - As shown in
Figs. 1-3 , aprojector type headlight 1 is provided with areflector 2, a light source 3, a convex lens 4, aholder 5, and ashade 6. - The
reflector 2 is composed of anupper reflector 21, arear reflector 22, and alower reflector 23. A reflection surface which is constituted by theupper reflector 21, therear reflector 22, and thelower reflector 23, is optically designed based on a free-form surface on the basis of paraboloid of revolution. InFig. 3 , a front focal point of areflection surface 24 of thereflector 2 is denoted by reference number F1, and a rear focal point thereof is denoted by reference number F2. - The light source 3 is fixed to the
rear reflector 22, and arranged so that a filament of the light source 3 is placed in a vicinity of the rear focal point F2 of thereflector 2. - The convex lens 4 is a plano-convex lens, and arranged so that a convex surface thereof faces forward. The convex lens 4 is also arranged at the position where the rear focal point of the convex lens 4 overlaps the front focal point F1 of the
reflector 2. - The
holder 5 includes a supportingsection 51 which supports thereflector 2,shade 6, and convex lens 4, and anengagement section 52 which makes the convex lens 4 be engaged with respect to the supportingsection 51. - The supporting
section 51 has a substantially tubular shape, and the convex lens 4 engages with a forward end portion of the supportingsection 51. In both side portions of the supportingsection 51, screwholes 511 into which screws 53 for fixing theengagement section 52 are inserted are formed respectively. Also a plurality of through-holes 512 for fixing theshade 6 andreflector 2 are formed respectively in the both side portions of the supportingsection 51. - The
shade 6 is arranged so that an upper end portion thereof is placed in a vicinity of the front focal point F1 of thereflector 2. Theshade 6 will be hereinafter described in detail.FIG. 4 is a front view showing a whole configuration of theshade 6, andFIG. 5 is a top view showing the whole configuration of theshade 6. - As shown in
Figs. 4 and5 , theshade 6 includes abody section 61 which defines a cut-off region, andattachment sections 62 which laterally extend from both side portions of thebody section 61 respectively. - The
body section 61 includes abase portion 611 which has a substantially semicircular shape when viewed from the above, and awall portion 612 provided to stand upward from an arcuate portion of thebase portion 611. - In a front-end central portion of the
base portion 611, acutout 613 is formed in a backward direction. On a top surface of thebase portion 611, a number ofrecess portions 614 extending along in a front-back direction are formed. - The
wall portion 612 is curved to have a substantially arcuate shape when viewed from the above, a convex portion of which faces rearward. A part of an upper portion of thewall portion 612 has a larger thickness than other portions thereof. On a front surface of thisthicker portion 615, agroove 616 is formed along a horizontal direction. On a front surface of thewall portion 612, a number ofrecess portions 617 extending along a vertical direction are formed. -
FIG. 6 is an enlarged view where a portion in a vicinity of thegroove 616 is enlarged, andFIG. 7 is a cross-section view showing a cross-section shape of theshade 6 ofFig. 6 viewed from a cutting-plane line VII-VII. As shown inFigs. 6 and7 , thegroove 616 extends along the horizontal direction, and is recessed rearward so as to have a U-shaped cross-section. Concretely, each of anupper corner portion 616a and alower corner portion 616b has a concave curved surface. - A length, width, depth, and installation position of the
groove 616 are respectively determined based on various experiments, simulations, and the like, so that an illumination intensity at point of B50L or B50R falls within an acceptable range (up to 0.5 [lx]). A size and an installation position of thethicker portion 615 are determined correspondingly to the length, width, depth, and installation position of thegroove 616. - As shown in
Fig. 4 , through-holes 621 are respectively formed in theattachment sections 62. Into the through-holes 621, fixing screws (not-shown) are respectively inserted through the throughholes 512 of the supportingsection 51. By making the fixing screws engage with therear reflector 22 through the through-holes rear reflector 22, the supportingsection 51, and theshade 6 are mounted. - Next, an operation of a
projector type headlight 1 will be described. - When the light source 3 is turned on, a part of irradiated light travels forward directly, and other lights are reflected by the
reflection surface 24 of thereflector 2 and travel forward indirectly. The parts of the lights traveling forward are cut off by thewall portion 612 of theshade 6. On the other hand, the lights passing above thewall portion 612 of theshade 6 pass through the convex lens 4 so that a region in front of the vehicle is irradiated with these lights. At this time, a part of the lights passing above thewall portion 612 of theshade 6 is reflected by the convex lens 4 (see Arrow L1 shown inFig. 3 ). Then, the lights reflected by the convex lens 4 are collected at the rear focal point of the lens 4, namely the front focal point F1 of thereflector 2. - For example, in the case of a
shade 6A not including a groove as shown inFig. 8 , because an upper end portion of awall portion 612a thereof is flat, the light reflected by the convex lens 4 is total-reflected by the upper end portion of thewall portion 612a and travels forward (see Arrow L2 shown inFig. 8 ). When the point of B50L or B50R is irradiated with the light total-reflected by thewall portion 612a, an illumination intensity of this point would exceed the acceptable range. - By contrast, according to the
shade 6 of the present embodiment, because thegroove 616 is formed in the front surface of the upper end portion of thewall portion 612, the lights traveling toward the front focal point F1 are diffusely reflected in thegroove 616 to be scattered about (see Arrows L3 shown inFig. 7 ). By this, the lights traveling toward the point of B50L or B50R can be reduced. - As described above, according to the
projector type headlight 1 of the present embodiment, because thegroove 616 is formed in the front surface of the upper end portion of theshade 6, the lights reflected by thegroove 616 in the front surface of theshade 6 can be scattered about. By this, the lights which are reflected by the front surface of theshade 6 and reach the point of B50L or B50R are reduced. As a result, the illumination intensity at this point can fall within the acceptable range. - Moreover, because the
groove 616 formed in the front surface of the upper end portion of theshade 6 extends in the horizontal direction, it becomes possible to make the light be scattered across a predetermined width in the horizontal direction. In other words, the lights traveling toward the point of B50L or B50R can be scattered about with one groove. - Furthermore, because the
groove 616 is formed in thethicker portion 615, a depth of thegroove 616 can be made as large as possible so that the scattering effect is improved. - Incidentally, it is needless to say that the present invention is not limited to the abovementioned embodiment, and can be changed appropriately.
- For example, as shown in
Fig. 9 , it is preferable that an upper portion of agroove 616b of ashade 6B has a concavecurved surface 620b or aninclined surface 621b (denoted by a dotted line inFig. 9 ). When the upper portion of thegroove 616b has thesurface 620b or thesurface 621b which slopes down toward the rear thereof in this way, the lights go into thegroove 616b are easily reflected downward by thesurface 620b or thesurface 621b. Consequently, the lights reflected downward by thesurface 620b or thesurface 621b do not reach the point of B50L or B50R naturally, and thereby the illumination intensity at this point can be reduced. - In a
shade 6C shown inFig. 10 , arecess portion 617c formed along the vertical direction extends to the upper end portion of athicker portion 615c of awall portion 612c so that the lights are scattered about. - The inventors of the present invention found out by various experiments and the like that the illumination intensity at the point of B50L or B50R (different depending on whether the headlight is used for right-hand traffic or for left-hand traffic) may exceed an allowable range because the lights reflected inside the projector type headlight are further reflected by the front surface of the shade to pass through the lens. In view of such problem, by forming the groove in the front surface of the upper end portion of the shade as recited in
claim 1, the present invention makes the lights reflected by the front surface of the shade be scattered about by the groove. By this, the lights reflected by the front surface of the shade become hard to arrive the point of B50L or B50R. Consequently, the illumination intensity at this point can fall within an acceptable range. - Moreover, because the groove in the upper end portion of the front surface of the shade extends along the horizontal direction, it becomes possible to make the light be scattered across a predetermined width in the horizontal direction. In other words, by one groove, the lights to reach the point of B50L or B50R can be scattered about.
- Furthermore, because the upper portion of the groove has the surface sloping down rearward, the lights going into the groove are easily reflected downward. Because the point of B50L or B50R is located at a position higher than a horizontal plane, the lights reflected by the surface downward do not reach the point of B50L or B50R naturally. In other words, since the upper portion of the groove has the surface sloping down rearward, it becomes possible to further reduce the illumination intensity at the point of B50L or B50R.
- Although various exemplary embodiments have been shown and described, the invention is not limited to the embodiments shown. Therefore, the scope of the invention is intended to be limited solely by the scope of the claims that follow.
