The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.In explanation, same reference marks refers to same member.
Car headlight device below in conjunction with accompanying drawing to the embodiment of the present invention elaborates.
Fig. 1 is the perspective view of the light source portion that comprises on car headlight device of the present invention.Fig. 2 means the decomposition diagram of the light source portion shown in Fig. 1.Fig. 3 sees the top view of the light source portion that Fig. 1 shows from top.
According to Fig. 1 to Fig. 3, light source portion can comprise: printed circuit board 110; Be arranged on first and second LED element 120,130 on printed circuit board 110; And the photoconduction 140 that forms and seal first and second LED element 120,130 on printed circuit board 110.
Printed circuit board 110 can be the PCB (Printed circuit board) made by the FR4 material, the McPCB (Metal core printed circuit board) made by metal material and by thin-film material form and the FPCB (Flexabe printed circuit board) of free bend in some, can be in addition but be not limited to the PCB made with other material.
In embodiment, printed circuit board 110 is the PCB that make with the FR4 material, is described as follows.
Printed circuit board 110 can comprise basal layer (not shown), and first and second LED element 120,130 is installed on described basal layer; With the copper foil layer (not shown) be electrically connected to; And be assemblied on described copper foil layer, and prevent that described copper foil layer is to the insulating barrier exposed outside (not shown).
Can assemble reflecting member 150 on printed circuit board 110.
Reflecting member 150 is likely described insulating barrier, or is assemblied on described insulating barrier, can be but the PSR that is not limited at least to comprise the reflective film of from Ag and A1 or has set reflectance.In other words, reflecting member 150 is that the light will irradiated from first and second LED member 120,130 at least can be to the both direction reflection of photoconduction 140.
The light that can form on the surface of reflecting member 150 but be not limited to that first and second LED element 120,130 is irradiated reflexes to the reflective-mode (not shown) of the top direction of photoconduction 140.
Now, first and second LED element 120,130 can be assemblied in first and second side surface part (not shown) of the mutual correspondence of printed circuit board 110.
The one LED element 120 is installed on described first side surface part of printed circuit board 110, can irradiate light to described the second side surface part direction, on the contrary, the 2nd LED element 130 is that described the second side surface part that is installed on printed circuit board 110 is irradiated light to described the first side surface part direction.
As a result, first and second LED element 120,130th, from mutual different direction, in other words, from described the first side surface part to described the second side surface part direction, irradiate light from described the second side surface part to described the first side surface part direction.
First and second LED element 120, the 130th, be installed on printed circuit board 110 with described first and second side surface part direction non-overlapping the to each other that be as the criterion, irradiate light between first and second LED element 120,130 of adjacent installation, the dark section occurred by first and second LED element 120,130 is minimized.
Reflecting member 150 is by first and second LED element 120, thereby 130 light that irradiate reflex to the direction of illumination that the top direction of photoconduction 140 is regulated light.
First and second LED element 120,130 can be side view class (side view type) assembly (package).
First and second LED element 120,130th, along with the use of side view class component, reflecting member 150 can be direction of light direction change above photoconduction 140.
In other words, as shown in Figure 3, a LED element 120 is to irradiate light to the first scope S1, thereby the 2nd LED element 130 is to reciprocal the second scope S2 of the first scope S1, irradiating region-wide equably the provide light of light to photoconduction 140.
Photoconduction 140 is to form on printed circuit board 110, can or cover first and second LED element 120,130 sealings.In other words, photoconduction 140 can be but the light that is not limited to irradiate from first and second LED element 120,130 upward with side at least one face or the optical resin (resin) of at least emitting to both direction.
Photoconduction 140 is, after on printed circuit board 140, first and second LED element 120,130 being installed, the sealing of the optical resin of liquefaction to be formed, and can form but be not limited to lens-type.
The formation of photoconduction 140 preferably makes the space between first and second LED element 120,130 minimize.
As mentioned above, car headlight device of the present invention is, after first and second LED element that will be formed by the side view class component is arranged on printed circuit board, to make it to be sealed by photoconduction 140, thereby makes light enlarge light quantity and optical efficiency to the region-wide irradiation of photoconduction 140.
Above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the described technical scheme of aforementioned each embodiment, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of the described technical scheme of various embodiments of the present invention.Protection scope of the present invention should make an explanation according to following claim scope, and all technical schemes in its equal scope should all belong to claim scope of the present invention.
