Description
Technical field:
This utility model belongs to lens technologies field, refers in particular to a kind of LED lens.
Background technology:
The head lamp of traditional motor-car uses the conventional light source such as Halogen light, xenon lamp.Compared to conventional light source,
LED light source has that luminous efficiency is high, color rendering properties is good, power consumption is few, energy-conserving and environment-protective, security reliability are high,
The advantage such as length, was used widely at each lighting field, was considered lighting source by industry service life
The Main way in market, has huge market potential.At present, the head lamp of motor-car also begins to use LED
Replace conventional light source.But, owing to LED is divergent light source, so in actual applications, often need to coordinate
Lens use to reach required brightness, illumination and uniformity requirement.The particularity of motor-car illumination, LED
Need to be equipped with corresponding lens to use.
Summary of the invention:
The purpose of this utility model is to provide the LED lens of a kind of simple in construction, low cost.
This utility model is achieved in that
A kind of LED lens, include support, are provided with the lens of elliposoidal on support, the lower end of lens
Be provided with the plane of incidence, upper end is provided with exit facet.
In above-mentioned a kind of LED lens, the major axis of the lens of described elliposoidal is vertically arranged.
In above-mentioned a kind of LED lens, described support is arch support, and lens are positioned at arch support,
The upper end of lens is connected with the highest point of arch support.
In above-mentioned a kind of LED lens, described arch support and lens are integral type structure, exit facet position
Upper surface in arch support.
In above-mentioned a kind of LED lens, the upper surface of described arch support be the spherical raised up or
Arcwall face.
In above-mentioned a kind of LED lens, described support is symmetrical structure.
In above-mentioned a kind of LED lens, described lens are centrally positioned on support.
In above-mentioned a kind of LED lens, the lower end of described support is provided with two spaced support peaces
Dress seat.
In above-mentioned a kind of LED lens, the baseplane of described support mounting seat is provided with downward projection.
In above-mentioned a kind of LED lens, described projection is symmetrical arranged.
The advantage that this utility model highlights compared to existing technology is:
1, the light source of 120 ° can be carried out refraction condensation by the lens of this utility model elliposoidal so that it is outwards
Launching angle light between 36 °, spotlight effect is good；
2, the lens of this utility model elliposoidal use integrated formed structure with support, and molding is fast, simple in construction,
Low cost；
3, this utility model is applicable on motor-car head lamp.
Accompanying drawing illustrates:
Fig. 1 is front view of the present utility model；
Fig. 2 is left view of the present utility model；
Fig. 3 is the A-A sectional view of Fig. 2；
Fig. 4 is upward view of the present utility model.
Detailed description of the invention:
With specific embodiment, this utility model is further described below, sees Fig. 14:
A kind of LED lens, include support 1, are provided with the lens 2 of elliposoidal, lens 2 on support 1
Lower end be provided with the plane of incidence 3, upper end is provided with exit facet.Wherein, the plane of incidence 3 is concave up spherical.
The major axis of the lens 2 of above-mentioned elliposoidal is vertically arranged.
Above-mentioned support 1 is arch support, and lens 2 are positioned at arch support, and the upper end of lens 2 is propped up with arch
The highest point of frame connects.
Certainly, support 1 can also be connected directly between the both sides of lens 2.
Above-mentioned arch support and lens 2 are integral type structure, and accordingly, exit facet 4 is positioned at arch support
Upper surface.
The upper surface of above-mentioned arch support, i.e. exit facet 4 are the spherical or arcwall face raised up.
Above-mentioned support 1 is symmetrical structure.
Said lens 2 is centrally positioned on support 1.
The lower end of above-mentioned support 1 is provided with two spaced support mounting seats 5.In support mounting seat 5
It is provided with installing hole 6.
The baseplane of above-mentioned support mounting seat 5 is provided with downward projection 7.Two protruding 7 are used for when installing
Location.
Above-mentioned protruding 7 are symmetrical arranged.
Operation principle of the present utility model:
LED light source is placed on the lower section of the plane of incidence 3 of lens 2, and light is injected from the plane of incidence 3, is then led to
Cross lens 2 to penetrate from the exit facet 4 exit facet or arch support of lens 2 upper end.By incident angle 120 °
The incident ray of left and right is adjusted to the emergent ray between 36 °.
Above-described embodiment is only one of preferred embodiment of the present utility model, not limits this reality with this
With novel practical range, therefore: all according to shape of the present utility model, structure, principle done etc.
Effect change, within all should being covered by protection domain of the present utility model.
