The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Figure 1, be sectional structure schematic diagram of the present invention, lens 1 are fixed on lens carrier 2 front ends, are provided with the light barrier assembly between lens carrier 2 and the speculum 7; With tapping screw 9, packing ring 8 bulb clamper 10 is fixed in the outside, speculum 7 rear ends, bulb clamper 10 can rotate, the lamp socket 11 that is inserted with bulb 13 embeds speculum 7 rear ends, the clamper of bulb clamper 10 is buckled 12 to be tipped in the packing ring 8, make bulb clamper 10 produce elastic deformation, form the fixing clamping force of bulb 13, thus fixing bulb 13.At speculum 7 front ends the light barrier assembly is set, again lens 1 is pressed into lens carrier 2, at last the insertion of lens carrier 2 alignment pins is namely formed PES dipped beam system with light barrier assembly locating hole.
Shown in Figure 2, be the perspective view of the light barrier assembly in this headlamp, the light barrier assembly comprises light barrier 5 and light barrier 6; Wherein: light barrier 6 cuts into and the inverted shape of dipped beam light type, forms dipped beam light type after the lens imaging principle is inverted amplification, and adds open polygon loophole 14, and guaranteeing has illumination output more than the "cut-off"line line; Because loophole does not have attenuation to light, the direct light of reverberation and bulb is easy to surpass limit value, so be provided with baffle plate sheet 5 at light barrier 6 towards the one side of speculum, described light barrier 5 tilts to be fixed on the light barrier 6 by screw 3 and nut 4, and be positioned at all the time speculum 7 inside, and partial occlusion loophole 14, in conjunction with Fig. 3 and shown in Figure 4, Fig. 3 is the rearview of light barrier, Fig. 4 is the A-A cutaway view of Fig. 3, described light barrier 5 tilts to be fixed on that formed angle is β on the light barrier 6, β with the angle of light barrier 6 formation 45o ~ 52o, so can pass through the angle of fine setting light barrier 6 and baffle plate sheet 5 after the assembling in the scope of 45o ~ 52o, adjust the light transmission capacity of loophole 14, exceed standard to avoid illumination.
Fig. 5 and shown in Figure 6 is respectively the structural representation of speculum and the B-B cutaway view of Fig. 5, for improving light output efficiency, single speculum 7 curved surfaces is divided into three districts:
The horizontal line of crossing the centre of luminescence is rotated counterclockwise angle [alpha] around Z axis, α=15 °, again with this straight line about the Y-axis image copying, two straight lines form 150 ° broken line, be divided into up and down two parts with broken line along the Z axis single mirror, its middle and upper part is divided into the I district, and the light of I district camber reflection can not blocked by light barrier 6, and most of reverberation of lower part curved surface will be blocked by light barrier 6 and cause light output efficiency not high.
Again the latter half curved surface is divided into two parts, take the bulb installed surface as datum level, divisional plane is apart from datum level 20mm, forms II district and III district, wherein, is the II district near the part of the centre of luminescence, is the III district away from the part of the centre of luminescence; The curved surface in II district can by adjusting, make reverberation pass through light barrier 6 and the effective light output of lens 1 formation, and the reverberation in III district be blocked substantially by light barrier 6.
Because the curved surface of shearing is relevant with former curved surface, can not make deformation operation, for making light barrier 6 block as little as possible the light of speculum 7 bottoms reflection, with industrial modeling software II district curved surface is rebuild, form single NUMBS curved surface, again this curved surface is rotated 0.3 ° around X-axis, then utilize surf deform instrument correction curvature of curved surface, deflection be between ± 0.98 (1 for indeformable, ± be deformation direction, deformation values is the amplitude of variation, more near 1, deflection is less), repeatedly import again the analysis of optics software emulation, the light that the II district is reflected is not adjusted to and is blocked by light barrier 6, and can be refracted to corresponding effective coverage by scioptics 1, as shown in Figure 7, thereby strengthen light output, improve the following illumination of "cut-off"line.
Owing to still having part light can pass the loophole 14 that light barrier 6 leaves in the III district, project more than the "cut-off"line after scioptics 1 refraction, cause illumination to exceed standard.Therefore, by calculating, the regional area in the III district increases delustring tooth 15, number and the Density Distribution of control delustring tooth 15 are dispersed a part of light, only have 1 outgoing of part light energy scioptics, reach and reduce the above illumination of "cut-off"line, ensure again certain luminance effects simultaneously.Step can appear in the curved surface after the adjustment, the meeting reflect stray light, must be by the UG Industrial Design Software surface smoothing that each is regional, it is continuous that requirement reaches G3 level curved surface, and then curved surface is imported ASAP optical analysis software repeatedly carry out Stray light analysis, finally determine compound curved surface of reflector Mathematical Modeling.
When needs adopt different bulbs, only need more lamp changing base inserts, be about to the speculum 7 that the lamp socket 11 of bulb 13 suppresses, change again based on halogen bulb H1, H7, H9, H11 or HID lamp and corresponding lamp socket thereof are arranged, again embed speculum 7 rear ends, therefore, every kind of speculum corresponding to bulb need not to make respectively mould, thus lower cost significantly.
In addition, each parts is connected with buckle with bolt with screw and is connected, like this connected mode can more change the bulb flexibly 13, speculum 7, light barrier assembly, lens carrier 2 or lens 1, thereby form various product.
The present invention is used identical light source, voltage with certain domestic hit product and certain hit product, contrast under the identical experiment condition environment, through the actual detection in the laboratory, illuminating effect and measured data are as follows:
1, illuminating effect is relatively:
Certain domestic hit product: brighter visually, both sides illumination descends very fast, and contrast is strong, and according to the characteristics of eyes, moving on to dark place from light needs a procedure of adaptation, and moment be can't see darker place, and the scope of sensation illumination has narrowed down.
Certain hit product: more even in whole illumination zone illumination, light and shade changes mild, only above 15 degree lines the dark space is arranged, and effectively illumination zone is larger, but whole illumination zone perceived brightness is bright not.
The present invention: more even in whole rules and regulations illumination zone illumination, illumination zone is maximum effectively, and brightness and the picture left above is approaching, and "cut-off"line is more clear attractive in appearance.
2, measured data:
Above data declaration: all data all meet rules, and each point all can satisfy limit value and sufficient safe clearance is arranged.
