From these figure, can find out, with aquaseal 3 the sealing shank 2a of lens 2 is sealed on the open circumferential groove 1a of a lamp body 1 of making by resin mold and can install to these lens 2 on the open front of lamp body 1 and define a lamp chamber.Sealing shank 2a extends on the periphery of these lens 2.The inside face that constitutes the lamp body 1 in this lamp chamber is coated with or scribbles the metal level of aluminium and so on, and particularly its lower surface portion is carried out surface treatment, so that the similar reflecting surface of reflecting surface of formation and light deflector hereinafter described.One reflex reflector 5 is arranged in this lamp chamber.This reflex reflector 5 has one and is used as the bulb 6 of light source and the shade 7 of the light that this bulb 6 of adjusting sends.This reflex reflector 5 comprises that one forms sidepiece 5b, a periphery 5c, a jack 5f and a long and narrow hole 5g in a reflex reflector chamber.
This reflex reflector 5 has a back side 51 of being processed into parabolic minute surface.One socket support holes 8 is arranged in this back side portion 51, so that bulb 6 can be plugged in wherein.The bottom 6a of bulb 6 installs in this socket support holes 8 by the pressure of retainer spring 9.In addition, reflex reflector 5 has a peripheral wall 52 that protrudes out forward along the periphery of this back side portion.The top of this peripheral wall and both sides protrude out near the open front of this lamp body 1 always, and have a recess 53 from its front edge towards the back at the bottom of the peripheral wall.Because the bulge size of this peripheral wall bottom is extremely short, so the front edge of this peripheral wall bottom is positioned at the edge part place of this back side portion 51.
In addition, to be designed to optical axis be adjustable to this reflex reflector 5.This reflex reflector 5 usefulness one ball-bearing casing portion 12 can vertically rotate as pivot point.This ball-bearing casing portion 12 is made of a ball seat 10 and a ball bearing pin 11 as S. A..This ball bearing pin 11 is fixed on this lamp body 1 and inserts in the ball seat 10 of support 54, and this support 54 is parts of this back side portion 51.In addition, also has a perpendicular alignmnet adjusting portion 15.The back side portion 51 that one perpendicular alignmnet nut 13 is fixed on reflex reflector is positioned on the support 55 on another part of ball-bearing casing portion 12 tops.This aligning nut 13 is spun on the perpendicular alignmnet governing screw 14 that is supported on rotationally on the lamp body 1.Therefore, rotation and regulate the position that is screwed into that this perpendicular alignmnet governing screw 14 can change this perpendicular alignmnet nut 13, thus this reflex reflector is vertically rotated, and the optical axis position of scalable reflex reflector 5 and this bulb 6.
On the other hand, the shade 7 that installs on this bulb 6 prevents that bulb light directly is upward through lens 2.Fig. 4 is the enlarged perspective of this shade 7.
The bottom that should go up shade portion 71 is fixed among the screw 5f of this reflex reflector back side portion 51 with the screw jack 75 of a screw 16 by means of the last shade portion of shade 7, and the long and narrow hole 5g of the holding element 78 insertion reflex reflector back side portions 51 that locate of shade portion 72 bottoms down.Therefore, this shade 7 is fixed on this reflex reflector 5 and is bearing in a pre-position of relative bulb 6 by this reflex reflector 5.Particularly, in the bottom of shade portion 71,72 up and down shade 7 just is fixed on the reflex reflector 5 respectively and can firmly be fixed on this shade 7 on the reflex reflector 5 and be subjected to suffered vibration of automobile and impact.
Therefore, when this shade 7 is fixed on this reflex reflector 5 and during by these reflex reflector 5 supportings, since last shade portion's 71 usefulness front faces 73 and cover portion 74 from the top cover bulb 6 the front, above and two sides, so the light general that sends of bulb 6 not front, the top and two sides of directive bulb 6.Because its basal surface portion 77 of 72 usefulness of shade portion has covered the downside of this bulb 6 down, does not therefore also have light to penetrate from this bulb 6 downwards.Importantly descend of the downside stretching, extension of the bottom surface sections 77 of shade portion 72 along bulb 6.In other words, this lower surface 77 is tabular.
Use this shade 7, in whole light of bulb 6 upwards forward light, to glazed thread, left to the right light and left to the right and the light that makes progress cover by the front face 73 and the cover portion 74 of shade portion 71 on this, as shown in Figure 6.In addition, downward light was forward penetrated connecting portion space, 76 both sides after lens 2 are mapped to the vehicle front bottom in the light that bulb 6 sends.In addition, reach backward in the light of this bulb 6 to the left and right that the light of both sides shines on this reflex reflector 5 through these reflex reflector 5 reflections after lens 2 according to vehicle front.
Therefore, do not have light in whole light of bulb 6 and directly make progress this lamp the place ahead of directive and make light directive vehicle front, thereby can obtain the required certain anti-glare distribution of light characteristic of car light through lens 2.Owing to also covered simultaneously to glazed thread, therefore can be prevented that the upper surface part of this lamp body 1 is overheated.The upper surface part of this lamp body 1 is by the top periphery wall portion thermal protection of this reflex reflector 5.Therefore, in this lamp chamber, circulate, thereby particularly the influence of the upper surface part received heat of this lamp body 1 is less by the air diffusion of bulb 6 heating.
On the other hand, the light that directly shines downwards in whole light of bulb 6 is covered by the bottom surface sections 77 of following shade portion 72, thereby prevents that these light from shining directly on the lower surface portion of this lamp body 1.Therefore, there is no peripheral wall at this position even form a recess 53 thereby the lower periphery wall portion of this reflex reflector 5 cuts a part, light also can not shine directly on the lower surface portion of this lamp body 1.Therefore, can prevent that this lower surface portion is overheated, thereby help to prevent that this lamp body from damaging because of being heated.
Therefore, to assemble this lamp, can prevent that this lamp body 1 lower surface portion is overheated, thereby prevent that lamp body from being burnt out with the identical mode of ordinary lamps that has a reflex reflector and a shade.Therefore, the front edge of the lower periphery wall of this reflex reflector 5 need not to extend near the open front position of this lamp body 1 as thermal protection sheet.Therefore can prevent owing to having the outward appearance that the space undermines this lamp between this reflex reflector 5 and the lamp body 1.In addition, in this case, the inside face that exposes the lower surface portion of this lamp body 1 even there is the recess of as close as possible this back side portion in the following peripheral wall portion of this reflex reflector 5 in this notched region, but owing to made to be similar to the reflective processed of the reflective processing of reflex reflector on the inside face of the lower surface portion of this lamp body 1, so the outside of lamp unlikely manifests the intersection between reflex reflector 5 and the lamp body 1.Therefore with regard to this one side, there is not the problem that influences this lamp outward appearance.In addition, lamp body bottom top need not a thermal protection sheet is set separately, thereby has reduced component number and installation steps.
Although the last shade portion of this shade is connected to down in the shade portion by its anterior connecting portion,, then can use two connecting portions down forward in this shade front part sides when light distributes when seeming important.In addition, although prevent vibration and the impact that automobile is subjected to the firm shade of lower support in the above-described embodiments,, then can omit this lower support if only can provide enough supports with upper supporting piece.
