Specific implementation mode
As shown in figs. 1-7, described the invention discloses a kind of LED automobile tail lamp, including speculum 1 and LED circuit board 2
Speculum is free-form surface mirror, and the LED circuit board is relatively fixed mounted on the front of the speculum, especially proximate to
The light-emitting surface of the edge of the speculum, the LED in the LED circuit board certainly has towards the front of the speculum
Certain angle of inclination, the light reflection sent out LED so as to the speculum is forwards.The speculum is made using free form surface
Type, relatively low to LED location required precision, moulding is changeable, and plasticity is strong, and required space is small, compact-sized, especially no longer needs
Longitudinal direction has larger space, even if can meet complicated space if under smaller lamps and lanterns space restrictive condition well
Modeling requirement.It can be arbitrary space curved surface that so-called free form surface, which refers to face type,.
The LED circuit board may include LED2-1, FPC plate 2-2 and aluminium sheet 2-3, be referred to as the small assembly of wiring board.
The aluminium sheet is the basic part of the LED circuit board, and the FPC plates are arranged on the aluminium sheet, and the LED is arranged described
On FPC plates.
The LED circuit board have flexibility, can bending arrangement, therefore contribute to coordinate free form surface speculum moulding,
The reflection for realizing the light of various spatial positions and various space angles makes the present invention relative to traditional reflecting LED car tail
Lamps and lanterns have better moulding plasticity, and can greatly reduce the requirement to mirror depths.
The LED automobile tail lamp is also provided with the interior lens 3 of dispersed material, sees the dash area region in Fig. 2, interior
Lens exterior surface area is also the light-emitting zone of the LED automobile tail lamp.The interior lens is arranged in the LED circuit board
With the front of the speculum.The light that LED is projected is first through interior lens described in speculum reflection directive, using described interior
Lens reflects and goes out.Light transfer route is as shown by the arrows in Figure 3.Dispersed material is a kind of material that can obscure point light source
Material, can uniform lighting effect using the interior lens of dispersed material.Therefore the present invention is in very limited lamps and lanterns space, no
The changeable demand of moulding is only met, while also having accomplished the uniformity of lighting.
The LED automobile tail lamp is additionally provided with control module 4, and the control module is fixed on the speculum, the control
Molding block realizes by connector with the LED circuit board and connects that the specifically described control module passes through connector and the LED
The FPC plates of wiring board are electrically connected.The FPC plates have flexibility, can be arranged with the LED circuit board
A FPC plate parts are extended except the aluminium sheet, and the control module is then connected to by connector beyond except the aluminium sheet
Part FPC plates on so that connection is flexible, without strictly limiting the installation site of the control module.
The LED circuit board can be fixedly mounted on the speculum.What is be in direct contact with the speculum is described
The aluminium sheet in LED circuit board.Based on part, be that the aluminium sheet is fixed on the speculum.
The LED circuit board can be fixed on from front on the speculum by way of blanching.It can be specifically institute
LED circuit board is stated to fix on the mirror by the blanching column 1-1 on the speculum.Compared in traditional automobile tail light from anti-
The assembling structure that mirror is put into LED circuit board behind is penetrated, the requirement to mirror depths can be greatly reduced, due to without office
Portion's thick-walled structure, therefore speculum front will not be caused to reprint books in a reduce format, and it is easy for installation.
Bending angle by controlling the aluminium sheet can control the light emitting angle of LED, by the height for controlling the aluminium sheet
Degree can control the luminous height of LED, and final adjustment light type is to meet the laws and regulations requirement of taillight.
For any one aforementioned described LED automobile tail lamp, can be advanced optimized in following many aspects.
1, the case where interior lens for being provided with the dispersed material, the speculum preferably uses the PC materials of white
Material is made, and the front of the speculum is not aluminized.The work(of taillight may be implemented by (the white PC materials) free form surface that do not aluminize
Energy.Along with the interior lens by the dispersed material realizes uniform lighting effect, make the front of the speculum i.e.
Make to be not provided with decorative pattern, remain able to the brightness requirement for meeting taillight, therefore the positive difficulty of processing of speculum can be substantially reduced.
This scheme, which not only eliminated, aluminizes, but also is not necessarily to processing patterns, and difficulty of processing significantly reduces, and cost savings are apparent.
2, the LED circuit board is preferably placed at the invisible area under the positive visual angle of the LED automobile tail lamp, usually leans on
The edge of the nearly speculum.
3, it is directed to a speculum, the LED circuit board can configure multiple, and be distributed across the speculum
Positive different location at, facilitate and meet complicated spatial modelling and diversified lighting effect needs.
In the present embodiment, the face type of the interior lens is the curved surface of two panels placed arrow type, as shown in Figure 2.In fact, also may be used
With using the space curved surface of other various possible shapes.
The present invention is based on can bending FPC adding aluminium plates structure on arrange LED, be fixed on from front by way of blanching
On free-form surface mirror, the requirement to mirror depths, and the modeling requirement of complexity easy to implement are significantly reduced.From
Space, moulding and practical set etc. are superior to traditional LED automobile tail lamp for being put into LED circuit board behind from speculum.
The technical concept and specific technological means of the present invention is not limited to automobile tail light, other lamps and lanterns can also answer
With.
