Light enters in light guide, and light occurs to be totally reflected and propagate in light guide in light guide, so as to which light is expanded into light source assembly
Peripheral region, such as upper and lower part, and projected from display part, some light extends the function of light-emitting device, such as can
To enrich lamp decoration design pattern using the light, strengthen the aesthetic property of light emitting device in vehicle, the structure on display part can also be passed through
Pattern, such as logo LOGO are made, so as to which the pattern can be shown when light-emitting device works.
It should be noted that effect can be lighted by cone tank formation homogeneous radiation on display part, taper here
Groove can also form various patterns, such as cone tank " one " word is arranged as a kind of micro-structural by planning the layout of cone tank
What row can produce " one " font lights effect, similarly, can produce other patterns or font.
As can be seen here, the utility model meets the demand of various shapes by using light guide and microstructure design,
Car light design pattern, and illumination and/or signal designation function and decoration functions share functionality light emitting module are enriched, is not required to
Extra luminescence light source, reduces cost, can meet requirement in vehicle moulding simultaneously and to illumination and/or signal indicating device
Laws and regulations requirement.And the light of light-emitting device is not extended on the market to peripheral region, such as lower regions, as luminous ornament
The design needed, also designed without using the luminous car light for producing moulding shape or LOGO of micro-structural.
Especially, it is 3 in the corner 142 of light guide 14, does not have corner at an angle of the quadrangle of light guide 14
142, as shown in Figure 5.It can be advantageous to shading coating is coated on the outer peripheral face of the quadrangle of light guide, to avoid in light guide 14
Side on light leak.Notch part 143 includes two sides, and the area of two sides is identical, and with ending the area phase at interface
Together.
In addition, lens 13 can only include intermediate lens, intermediate lens can be structure as a whole with light guide 14, light guide 14
Opening portion 144 may be constructed such that intermediate lens is stamped at top, so, it is possible to reduce a part, and eliminate lens
Installation is fixed.In this case, light guide 14 can not be fixed by fixing hole, that is, be not provided with fixing hole 141, and light guide 14 can be with
Be placed in the groove of housing 16, after front wall 12 installs, light guide 14 be directly clamped in front panel 12 and housing 16 it
Between, the light leakage phenomena caused by perforate on light guide 14 is thus also eliminated, while save installation steps.Further, this practicality
New light-emitting device also includes multiple reflective cone shaped granules, and its quantity is identical with the quantity of multiple cone tanks 1451, in institute
State in the case that display part is construed as including equally distributed multiple cone tanks 1451, the multiple reflective cone shaped granule can
To be optionally filled in cone tank 1451, to close the cone tank in display part.In this way, user can be certainly
Cone shaped granule is filled into cone tank by ground, arranges to form specific pattern using cone shaped granule, when light-emitting device works,
Due to cone shaped granule refraction and reflection light, therefore recognizable pattern can be produced.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be changed in the case where not departing from principle of the present utility model and spirit.This practicality
The new scope of application is defined by the appended claims and the equivalents thereof.
