Detailed description of the invention
Be described in detail to the utility model below in conjunction with drawings and Examples, it should be noted that in the following description content, similar element represents with identical numbering.
Consult Fig. 1,2,3, the first embodiment of the utility model car light, Ke Zuo Wei Brake car light, daytime portable lighter etc. car light, and to comprise: lamp housing 1, mount pad 2, and two luminescence units 3.
This lamp housing 1 comprise a shell body 11, defining space 110 in a shell be arranged on front side of this shell body 11 in conjunction with cover 12, and one be arranged on this shell body 11 with this in conjunction with the diffuser 13 on front side of cover 12.This external form in conjunction with cover 12 roughly conforms to the external form of this shell body 11, and can dock with this shell body 11 and combine.This comprises one in conjunction with cover 12 and runs through setting and the light output groove 121 of left and right to length to extension.This diffuser 13 covers this in conjunction with cover 12 and space 110 in this shell, and this diffuser 13 can be colourless light-permeable cover body, also can be coloured light-permeable cover body.Such as, when the present embodiment being applied to the 3rd Brake car light, this diffuser 13 can be red light-permeable cover body, produces the effect of red light when making this car light luminous.This lamp housing 1 non-the utility model improvement emphasis, enforcement also must not limit the number of elements of its structure and composition.
This car light also comprises one and to be arranged in this lamp housing 1 and for driving the driver (not shown) of described luminescence unit 3 luminescence, and some are for connecting the connection line of this driver and described luminescence unit 3, but because this driver and the non-the utility model of connection line improve emphasis, therefore no longer describe in detail.
In the shell that this mount pad 2 is arranged at this lamp housing 1 in space 110, and comprise the bridge connector 21 that is positioned at central authorities, and two are connected to the front side of this bridge connector 21 and the fixing body 22 that arranges of left and right.What each fixing body 22 comprised that a roof 222, extended to the frame wall 221, extended from this wall 221 apical margin in left and right extends from this wall 221 root edge forward forward carries wall 223, and the several limited walls 224 extended upward from this year wall 223 and several contacting wall 225.Described limited wall 224 each other between left and right every.Described contacting wall 225 also between left and right every, and position than described limited wall 224 near rear, stagger respectively with about the position of described limited wall 224 in the position of described contacting wall 225.By this wall 221, roof 222, carry wall 223, limited wall 224 and the design of contacting wall 225, this fixing body 22 is formed and is similar to lateral trench space, can plug for luminescence unit 3.
In the shell that described luminescence unit 3 is arranged at this lamp housing 1 in space 110, and to be installed on respectively on the described fixing body 22 of this mount pad 2, and then in left-right situs, and the position of described luminescence unit 3 is respectively to should in conjunction with the position of the light output groove 121 of cover 12.Each luminescence unit 3 comprises a circuit substrate 31, several LED wafer 32, and a packaging body 33.
This circuit substrate 31 of each luminescence unit 3 is the long slab sheet of left and right to extension, and comprises contrary front surface 311 and a rear surface 312.This circuit substrate 31 is an aluminium sheet, has good radiating effect.Described LED wafer 32 is positioned at the front surface 311 of this circuit substrate 31, and along the length direction of this circuit substrate 31 and spaced-apart relation.The light that described LED wafer 32 sends penetrates forward by this light output groove 121 in conjunction with cover 12 and this diffuser 13.In the present embodiment, described LED wafer 32 is blue light wafer.
This packaging body 33 is positioned at the front surface 311 of this circuit substrate 31 and covers described LED wafer 32, LED wafer 32 encapsulation to be fixed on this circuit substrate 31.This packaging body 33 is the macromolecule material of light-permeable, and wherein containing yellow fluorescent powder, the blue light of LED wafer 32 described in Absorbable rod and be subject to exciting generation gold-tinted, this gold-tinted forms white light again and also penetrates forward with blue light.
Described luminescence unit 3 is arranged on the mode on this mount pad 2, mainly respectively by the left and right sides of described fixing body 22, is inserted on fixing body 22 by the length direction of the luminescence unit 3 on each limit along the fixing body 22 on each limit.After installation, corresponding between this fixing body 22 and this luminescence unit 3, the frame wall 221 of this fixing body 22 is positioned at this circuit substrate 31 rear, this roof 222 and this year wall 223 fasten top in this circuit substrate 31 and below respectively, described limited wall 224 abuts the front surface 311 of this circuit substrate 31 close to root edge place, luminescence unit 3 restriction is can be used for be fixed on this fixing body 22, coordinate described contacting wall 225 to abut the rear surface 312 of this circuit substrate 31 close to root edge place again, reach the better effect fastening positioning luminous unit 3.It can thus be appreciated that, the combination of described luminescence unit 3 and this mount pad 2, quite simple and be easy to carry out, snap in as long as plug.
Due on this circuit substrate 31 of each luminescence unit 3 of the present utility model, be packaged with this several LED wafer 32, be a kind of COB (Chip On Board) packing forms simultaneously.COB packaged type, relative to the mode of tradition by each LED individual packages separately, has the simple advantage of line design, and can avoid in the past will independently LED separately, and what welding or screw lock caused in vehicle lamp body inside takes a lot of work, shortcoming consuming time.And because described LED wafer 32 is directly packaged on the good circuit substrate of thermal conductivity 31, can reduce thermal resistance, there is preferably radiating effect, and heat radiation evenly, heat can be avoided for the impact of LED wafer 32, thus improve production reliability and service life.And also because the utility model excellent in heat dissipation effect, radiating fin set in traditional car light can be omitted, thus reduce in order to dispel the heat done design with reduce costs.The utility model, after improved heat radiation problem, just can use the more lower powered LED of LED used relative to general known car light, so just can produce identical luminosity, and the heat that the utility model is produced is just less.And each luminescence unit 3 only just can encapsulate all LED wafers 32 with this single packaging body 33 simultaneously, outgoing light homogeneity is better compared to the arrange in pairs or groups light-out effect that produces of the independent LED of tradition many.
In sum, designed by the innovation structure of luminescence unit 3, make that the overall structure of the utility model car light is simple, easy to assembly, thermal diffusivity is good, and can improving product reliability.
Consult Fig. 4, second embodiment of the utility model car light, roughly the same with the structure of this first embodiment, different places is, the present embodiment also comprises the light-strip 4 (Fig. 4 only illustrates) in two these shells being arranged on this lamp housing 1 (Fig. 3) in space 110 (Fig. 3).Described light-strip 4 is arranged on front side of the packaging body 33 of described luminescence unit 3 respectively.Each light-strip 4 extends along the length direction of this circuit substrate 31, and comprise one towards the incidence surface 41, of this packaging body 33 in contrast to this incidence surface 41 exiting surface 42 forward, and several from this incidence surface 41 towards the outstanding guide-lighting micro-structural 43 of this packaging body 33.Described guide-lighting micro-structural 43 is along the length direction left-right situs of this circuit substrate 31.
The light of the luminescence unit 3 of the present embodiment can first penetrate via after light-strip 4 again, by the design of the described guide-lighting micro-structural 43 of light-strip 4, and the leaded light effect of light-strip 4 entirety, can luminosity be made evenly, brightness is higher.For daytime, the application of portable lighter has very large benefiting.
