Description
Technical field
The present invention relates to a kind of identification light and its lens, more particularly to a kind of vehicle side-marker lamp and its lens.
Background technology
Identification light is applied in people's daily life very extensively, especially on automobile.The master of automobile side-marker lamp
It acts on, is the presence for being convenient for people to the vehicle from side, this safety of driving a vehicle and stop to Vehicular night plays most important
Effect.
Existing vehicle side-marker lamp is mostly to cover light source using lens, and lens are typically that outer surface is arc-shaped, interior table
Face is then the pyramid polyhedral structure of array, and light passes through after lens, and hot spot is spuious not to be concentrated, and seriously affects out light efficiency
Rate, it is more difficult to meet the light distribution requirement of side-marker lamp regulation, often be merely able to the light source using larger power consumption.
The content of the invention
The present invention provides a kind of light efficiency high vehicle side-marker lamps and its lens, which overcome present in background technology
Deficiency.The technical solution adopted by the present invention to solve the technical problems is：
Vehicle side-marker lamp lens, are hollow-core constructions, including cover part and from the bottom of the cover part to downward
The shell portion to be formed is stretched, the cover part is upward convex shell structure, and the upper surface of the cover part is arcwall face,
The lower surface of the cover part has multiple grooves, the cover part transversely cutting in vertical plane, on inner surface
The projection of recess sidewall is arc curve；Cover part cutting along longitudinal direction in vertical plane, inner surface fovea superior groove sidewall
Projection be free curve.
Vehicle side-marker lamp, including light source board, conducting wire and lens, which is hollow-core construction, which is arranged on this
Among lens, which is electrically connected with the light source board, which includes cover part and downward by the bottom of the cover part
The shell portion extended to form, the cover part are upward convex shell structures, and the upper surface of the cover part is arc
Face, the lower surface of the cover part have multiple grooves, the cover part transversely cutting, inner surface in vertical plane
The projection of fovea superior groove sidewall is arc curve；Cover part cutting along longitudinal direction in vertical plane, inner surface upper groove side
The projection of wall is free curve.
Compared with background technology, it has the following advantages that the technical program：
The side wall of groove on the lower surface of the cover part is free form surface, and groove is by one or more freely bent
Face surrounds, and improves the diffusion effect to light, and particularly gained hot spot is continuum on the receiving plane at 1 meter of its outer
Middle rectangular light spot has better light emission rate, therefore, the light intensity of identification light regulation is just disclosure satisfy that using the light source of lower power consumption
Spreading requirements.

Specific embodiment
Fig. 1 to Fig. 9 is refer to, vehicle side-marker lamp includes light source board 10, conducting wire 20, lens 30 and rubber ring 40.This is thoroughly
Mirror 30 is hollow-core construction, which is arranged among the lens 30, which is electrically connected with the light source board 10.
The lens 30 include cover part 32 and the shell portion 34 being downwardly extending by the bottom of the cover part.
The cover part 32 is upward convex shell structure, and the upper surface 321 of the cover part 32 is arcwall face.The cover portion
Divide 32 lower surface there is multiple grooves 323, the cover part 32 transversely cutting in vertical plane, lower surface upper groove
The projection of 323 side walls is arc curve (as shown in Figure 6).The cover part 32 cutting along longitudinal direction, following table in vertical plane
The projection of 323 side wall of face upper groove is free curve (as shown in Figure 5).That is, on 32 lower surface of cover part
The side wall of groove 323 is free form surface, and each groove 323 is surrounded by one or more pieces free form surfaces.
Preferably, the upper surface 321 of the cover part 32 is arc spherical surface, naturally it is also possible to be ellipse.The face
The shape of the level cross-sectionn of cover 32 can be circular or ellipse or rectangle etc..The inner surface of the shell portion 32
On be arranged with a pair of of /V table top 341, the light source board 10 is supported on the /V table top 341.The shell portion 34
Outer surface be equipped with screens rib 342.The rubber ring 40 entangles the lens barrel part 34, the screens rib 342 with
The rubber ring 40 is clamped.
Light source 12, certain 12 quantity of light source are unrestricted there are three tools on 10 top surface of light source board.Inside the lens 30
The light source board 10 is sealed among the lens 30 by the light source board 10 with lower part encapsulating.What the light source 12 on the light source board was sent
Light on described about 1 meter of remote receiving plane of light source 12 after the lens 30 by forming rectangular light spot (such as Fig. 9 institutes
Show), be in into the stronger light intensity of hot spot in 0 ° of level and ± 45 ° of the range of linearity.
Fig. 7 and Fig. 8 are refer to, lens of the invention are changed by the shape of 32 lower surface groove 323 of opposite cover
0 ° of level and ± 45 ° of ranges of linearity are in into so that the stronger light intensity of hot spot, the light distribution requirement of this and side-marker lamp regulation
It matches, there is good light emission rate.
The above is only present pre-ferred embodiments, therefore cannot limit the scope implemented of the present invention according to this, i.e., according to
The equivalent changes and modifications that the scope of the claims of the present invention and description are made all should still belong in the range of the present invention covers.
