With reference to figure 1-3, comprise main body 1 according to the bulb of car light of the present utility model, it can be such as the main body of metal or alloy, the main body of such as aluminium alloy.This main body 1 can be provided with installed part 5 for by bulb integral installation in the lamp socket on such as automobile.
One supporting body 2 extends from the side of main body 1, and forms reciprocal primary principal plane 21 and secondary principal plane 22.Supporting body 2 has less thickness between primary principal plane 21 and secondary principal plane 22, such as, be less than 3mm, is preferably less than 2.5mm.Primary principal plane 21 is provided with the first solid state light emitter 31, and the second solid state light emitter 32 is installed on secondary principal plane 22.This first solid state light emitter 31 and the second solid state light emitter 32 are as the light source of the dipped beam of bulb.In the present embodiment, this first solid state light emitter 31 and this second solid state light emitter 32 are respectively the linearly aligned multiple light emitting diode (LED) of bearing of trend along described bearing part 2.These light emitting diodes can be arranged in two printed circuit board respectively, and this two printed circuit board is installed to the both sides on bearing part 2 respectively, thus the surface of this two printed circuit board is respectively as primary principal plane 21 and secondary principal plane 22.
Primary principal plane 21 is also provided with towards the first reflector of the first solid state light emitter 31, for the light of reflection from the first solid state light emitter 31; And secondary principal plane 22 is also provided with towards the second solid state light emitter 32 second reflector, for the light of reflection from the second solid state light emitter 32.In the embodiment shown in Fig. 1-3, have in the side (being shown as the downside of the first solid state light emitter 31 in Fig. 2-3) of the first solid state light emitter 31 and provide this first reflector from the inner sunken face 411 of the first outstanding projection 41, first projection 41 of primary principal plane 21.Have in the side (i.e. the downside of the second solid state light emitter 32) identical in the side of the first solid state light emitter 31 with the first projection of the second solid state light emitter 32 and provide this second reflector from the inner sunken face 421 of the second outstanding projection 42, second projection 42 of secondary principal plane 22.Inner sunken face 411 and 421 all smooth enough to reflect the light respectively from the first solid state light emitter 31 and the second solid state light emitter 32 efficiently.
In order to the light enabling bulb send basic same intensity in the left and right sides, usually the first solid state light emitter 31 and the second solid state light emitter 32 is made to have same configuration, namely there is same LED unit quantity, there is same luminous power, there is same size, and the same position be installed in respectively on primary principal plane 21 and secondary principal plane 22 and towards.
As shown in Figure 4, the light that first solid state light emitter 31 sends installs the reflective surface at the car light lamp socket rear of this bulb through the inner sunken face 411 of the first projection 41 approximately towards (as shown by arrows) arrival after upper reflection, and then this light reflects away to vehicle front by the reflective surface at this car light lamp socket rear again; Same, the light that second solid state light emitter 32 sends installs the reflective surface at the car light lamp socket rear of this bulb through the inner sunken face 421 of the second projection 42 approximately towards (as shown by arrows) arrival after upper reflection, and then this light reflects away to vehicle front by the reflective surface at this car light lamp socket rear again.Like this, the passing beam to vehicle front projection is formed after the reflective surface reflection that the light that the first solid state light emitter 31 and the second solid state light emitter 32 send combines through inner sunken face 411 and 421 and car light lamp socket rear.
In order to make the almost light emitting region of 360 degree of illumination effect close to generic halogen lamp of the first solid state light emitter 31 and the combination of the second solid state light emitter 32, distance d1 between primary principal plane 21 and secondary principal plane 22 should be as far as possible little, such as be no more than 2.5mm, with make the first solid state light emitter 31 and the second solid state light emitter 32 as far as possible close.
In one embodiment, first reflector (the i.e. inner sunken face 411) length on the bearing of trend of bearing part 2 is preferably the 1-1.5 of the length of the first solid state light emitter 31 on the bearing of trend of bearing part 2 doubly, and the second reflector (the i.e. inner sunken face 421) length on the bearing of trend of bearing part 2 is preferably the 1-1.5 of the length of the second solid state light emitter 32 on the bearing of trend of bearing part 2 doubly.And, first solid state light emitter 31 is positioned at completely within the development length of described first reflector on the bearing of trend of bearing part 2, and the distance d2 of one end of the close main body 1 of one end of the close main body 1 of the first solid state light emitter 31 distance the first reflector is no more than 1mm; And second solid state light emitter 32 be positioned at completely on the bearing of trend of bearing part 2 within the development length of the second reflector, and the distance d2 of one end of the close main body 1 of one end of the close main body 1 of the second solid state light emitter 32 distance the second reflector is no more than 1mm.
The inner sunken face 411 of the first projection and the inner sunken face 421 of the second projection are bowl-shape three-dimension curved surface.In one embodiment, the bottom of this inner sunken face 411 and 421 is basic planes, and is forming space three-dimensional curved surface perpendicular to the wall portion of (side except primary principal plane 21 or secondary principal plane 22) on three directions of bottom.
With reference to figure 5, in one embodiment, with the position of the first solid state light emitter 31 above the first projection 41 in the direction perpendicular to described primary principal plane 21, the distance d3 of the top edge of top distance first solid state light emitter 31 of the inner sunken face 411 of the first projection is 0.4-0.6mm, and the height d4 of top to the bottom of the inner sunken face 411 of the first projection is about 1.5 times of the height of the first solid state light emitter 31.
By the first reflector designed above, the light that the first solid state light emitter 31 and the second solid state light emitter 32 can be sent as much as possible approximately towards upper reflection to improve the utilization rate of the light of light source.
Continue with reference to figure 5, second projection 42 is positioned in the imaginary plane (not shown) being parallel to primary principal plane 21 or secondary principal plane 22 about primary principal plane 21 and secondary principal plane 22 middle, with on the position of the first projection 41 symmetry, and there are the shape and size roughly the same with the first projection 41.The α but the inner sunken face 411 of inner sunken face 421 to the first projection 41 in the second projection 42 outwards flips an angle towards the direction away from this imaginary plane more, is preferably about 15 degree.Such design is that the light in order to make the inner sunken face 421 in this second projection 42 reflect is reflected with the level height that the light reflected than the inner sunken face 411 in the first projection 41 is lower, thus in this secondary principal plane 22 side, the light sent by the second solid state light emitter 32 can not to be projected onto vehicle front higher than the height of the second solid state light emitter 32 place level height substantially.This is the pressure safety standard in order to meet usually to automobile short-distance.
Every country all has pressure safety standard to automobile short-distance usually, passing beam comprising the meeting side (i.e. driver side) at automobile can not project higher than the level height of car light, in order to avoid cause the driver of the automobile in contiguous opposite carriageway be subject to the interference of this passing beam and cause accident when meeting.Due to the standard path of country variant and the difference of automobile making standard, the vehicle of some countries (such as British commonwealth of nations) is by road left driving, and the vehicle of some countries (such as China) travels by the right side of road.Therefore, for country variant automobile lamp for passing beam arranged on left and right sides projection level height regulation may be different.For country (the such as China of vehicle by travelling on the right side of road, need level height that passing beam projects to vehicle left side not higher than the height of car light), for this reason, as shown in accompanying drawing 4-5, first projection 41 is arranged on from the free end of the bearing part 2 of car light to the left side the direction that body 1 looks over, and the second projection 42 being arranged on right side, the ray cast with reduced levels height reflected with the inner sunken face 421 made via the second projection 42 is in the left side of automobile direction of advance.For the country of vehicle by road left driving, the position of the first projection 41 and the second projection 42 can be exchanged, or the structure of whole bulb is carried out mirror image relative to this imaginary plane, and the ray cast with reduced levels height reflected with the inner sunken face 421 made via the second projection 42 is on the right side of automobile direction of advance.
As shown in Figure 2 and Figure 6, first projection 41 is also formed the wedge angle 412 blocking the light that the first solid state light emitter 31 projects towards the direction contrary with the bearing of trend of bearing part 2, and is also formed with the wedge angle 422 blocking the light that the second solid state light emitter 32 projects towards the direction contrary with the bearing of trend of bearing part 2 in the second projection 42.This wedge angle 412 and 422 can be the wall extended substantially vertically from one end of the close main body 1 of the first projection 41 and the second projection 42.What the light that this wedge angle 412 and 422 prevents the first solid state light emitter 31 and the second solid state light emitter 32 to send was irradiated to lamp socket rear backward is produced less desirable dazzle for the reflecting surface of distance light by reflecting.Which further improves the quality of dipped beam.The example of the structure for installing the first projection 41 and the second projection 42 is also show in Fig. 2 and Fig. 6.Installing plate 413 and 423 is connected respectively to the first projection 41 and the second projection 42.Therefore, by screw or rivet, installing plate 413 and 423 is respectively fixed to primary principal plane 21 and secondary principal plane 22, the first projection 41 and the second projection 42 can be fixed to the first projection 41 and the second projection 42.
Refer again to Fig. 1-2, primary principal plane 21 be also provided with the 3rd solid state light emitter (not shown), described 3rd solid state light emitter on the bearing of trend of bearing part with the first projection 41 spaced apart and than the first projection 41 closer to main body 1; Secondary principal plane 22 is also provided with the 4th solid state light emitter 34, and described 4th solid state light emitter 34 is spaced apart and than described second projection 42 closer to described main body 1 with the second projection 42 on the bearing of trend of bearing part 2.3rd solid state light emitter and the 4th solid state light emitter 34 are used as the high-beam light source of car light, and its light produced projects vehicle front as driving beam after directly carrying out reflection by the reflective surface be positioned on lamp socket.3rd solid state light emitter and the 4th solid state light emitter equally all can comprise multiple luminescence unit, such as multiple light emitting diode.And, 3rd solid state light emitter also has substantially identical configuration with the 4th solid state light emitter, namely there is same LED unit quantity, there is same luminous power, there is same size, and the same position be installed in respectively on primary principal plane 21 and secondary principal plane 22 and towards, to produce the light beam of basic same intensity in the left and right sides of bulb.
Because the first projection 41 and the second projection 42 to be separately positioned on primary principal plane 21 and secondary principal plane 22 and respectively near the first solid state light emitter 31 and the second solid state light emitter 32, and there is relatively little size, it can not block the light that the 3rd solid state light emitter and the 4th solid state light emitter send substantially.Therefore, the light that the 3rd solid state light emitter and the 4th solid state light emitter send can be positioned at more the reflective surface of the car light at bulb rear reflect, thus this bulb has larger intensity and better distributing homogeneity for the distance light that car light provides.
As described in Fig. 1-3, the far-end extended from main body 1 at bearing part 2 forms shading light part 23, to stop by the first solid state light emitter 31 and the second solid state light emitter 32 at the light sent with (preferably left and right with bearing of trend be all not less than 40 degree) in the angled scope of the bearing of trend of bearing part 2.Like this, the light sent by light source can be avoided to project directly to vehicle front to form dazzling light beam.Advantageously, bearing part 2 directly can be formed as the flat and shape that two is plentiful in middle part, such as, cut out both sides, cylindrical middle part and the shape that formed.In the middle part of this, the both sides difference mounting circuit boards of plat part is to form primary principal plane 21 and secondary principal plane 22, and on the cylinder of free end, form shading light part 23, simultaneously because whole bearing part 2 can be made up of thermal conductive metallic material (such as aluminium alloy), the larger quality of the plentiful cylinder at its two ends and large surface area can conduct as radiator and dissipate by the heat produced during multiple light source works on primary principal plane 21 and secondary principal plane 22, to improve the hot property of bulb.
As described in Fig. 1-2, in one embodiment, radiator 6 is removably connected with in the side contrary with the bearing of trend of bearing part 2 of main body 1.Radiator 6 such as can be threaded connection on the threaded rod 11 of the main body 1 being detachably connected to bulb.Because radiator 6 removably connects, therefore, when bulb is installed to lamp socket, can first not tool for mounting have the radiator 6 of larger volume, so that the installation of bulb.And after bulb is installed to lamp socket, can radiator 6 be screwed in the threaded rod 11 of the main body 1 exposed from lamp socket rear portion from lamp socket rear portion again, to realize from supporting body 2 through the heat conduction path of main body 1 to radiator 6.
Radiator 6 can have chimney structure, namely from entrance 61 to the gas channel of outlet 62, so that make the heated air of radiator 6 inside flow out fast by stack effect and make cool exterior air flow into, to accelerate the dissipation of heat of radiator, thus improve the hot property of bulb.
In addition, the main body 1 of bulb can also be provided with installed part 5, so that be fixed in lamp socket by bulb.This installed part 5 is similar with the installed part of generic halogen vehicle light bulb, thus repeats no more.
The passing beam that the bulb of the car light of embodiment of the present utility model sends in the horizontal direction on the side of bulb is generally within below the level height of bulb, namely there is beam cut-off line clearly, and there is no glare area at this dead line upper area, thus meet the pressure safety requirements to car light dipped beam.The driving beam that the bulb of the car light of embodiment of the present utility model sends has higher intensity and beam distribution is comparatively even.Therefore, the bulb of the car light of embodiment of the present utility model can substitute the bulb of traditional halogen bulb as the head lamp of automobile.
