Parabola reflector as light concentrating components, but owing to conventional LED lamp bead volume is much smaller than incandescent lamp bulb,
Still using tradition reflector spotlight effect unsatisfactory, then the optimization to reflective cup type beam condensing unit designs
The most never stopped, and how to make this type of beam condensing unit obtain more preferable spotlight effect by simple and effective design
With more attractive emergent ray, remain the target that current lamp decoration industry is constantly pursued.
[summary of the invention]
This utility model is for above-mentioned technical problem, it is provided that a kind of spotlight effect is good, the simple LED of manufacturing process
Lamp focused lamp cover.
In order to solve above-mentioned technical problem, utility model is achieved through the following technical solutions:
A kind of LED focused lamp cover, including reflector and the collecting lens being arranged in reflector, described
Collecting lens is arranged on the middle part of described reflector, and the reflective surface of reflector is divided into by the installation of collecting lens
Lower two parts；The upper reflective surface of reflector and collecting lens surround LED and accommodate chamber, the table of described upper reflective surface
Face is made up of evenly distributed little convex surface illuminator, and described little convex surface illuminator is tetragon, and four limits are by instead
Light cup inner surface equally distributed cross section circle and parabola form；The lower reflective surface surface of reflector is uniformly divided
It is furnished with parabola.From the point of view of the opening part of reflector, the most described parabola is equally distributed radiation
Shape straight line, upper reflective surface include equally distributed radial straight line and concentric circular composition reticulation patterns, lower instead
Bright finish then includes the equally distributed radial flower-shaped decorative pattern of the rectilinear(-al) sun.Adjacent the two of described lower reflective surface
Zone cross-sectional between parabola is the symmetrical arc that middle high both sides are low.Here parabola refers to whole
Reflective parabola falls at a range of line segment of reflector.
Further, the main body of described collecting lens is cylindrical, the most flat cylinder, also
Being exactly circular slab, the upper surface of collecting lens i.e. surrounds LED and accommodates the surface in chamber to be evenly distributed with cross section be straight
The donut of angle triangle, the lower surface of collecting lens is evenly distributed with radial straight line.Described right angle
Its right-angle side of triangle is towards side, the concentric circular center of circle.It is adjacent radial for the lower surface of described collecting lens
Zone cross-sectional between straight line is the symmetrical arc that middle high both sides are low.Its horizontal stroke of the lower surface of described collecting lens
Cross section is the symmetrical arc that middle high both sides are low.
Further, described collecting lens surface is fuzzy face.Described collecting lens is made up of transparent material.
Further, described collecting lens and reflector use buckle to install.
This utility model is by improving the shape of collecting lens and reflective cup reflective surface and optimize, right
The upper and lower surface of collecting lens and reflective cup has carried out different designs, thus optimizes the folding of LED light source
Penetrate and reflection direction, reached to improve the purpose of reflector spotlight effect.

[detailed description of the invention]
Below in conjunction with detailed description of the invention, utility model is described in further detail.
LED focused lamp cover as shown in Figure 1, including reflector 1 and the optically focused being arranged in reflector 1
Lens 2, described collecting lens 2 is arranged on the middle part of described 1 reflector 1, and the installation of collecting lens will be anti-
The reflective surface of light cup is divided into reflective surface 1.1 and lower reflective surface 1.2；The upper reflective surface 1.1 of reflector 1 is with poly-
Optical lens 2 surrounds LED and accommodates chamber.The surface of described upper reflective surface 1.1 is reflective by evenly distributed little convex surface
Mirror 1.11 forms, and little convex surface illuminator 1.11 is tetragon, and four limits are equally distributed by reflective cup inner surface
Cross section circle 1.12 and parabola 1.13 form；Lower reflective surface 1.2 surface of reflector 1 is evenly distributed with parabolic
Line 1.21.
As indicated with 2, from the point of view of the front view of reflector, parabola 1.13 and parabola 1.21 are visually
Equally distributed radial straight line, upper reflective surface 1.1 includes by equally distributed radial straight line and concentric circular group
The reticulation patterns become, lower reflective surface 1.2 then includes the equally distributed radial flower-shaped decorative pattern of the rectilinear(-al) sun.
Zone cross-sectional outline between its adjacent two parabolas 1.21 of lower reflective surface 1.2 is that middle high both sides are low
Symmetrical arc, be can be seen that by edge wheel profile 1.22.The intersection of reflective surface up and down of reflector is provided with installation
Mouth 1.3, is used for installing collecting lens.
As it is shown on figure 3, the upper surface of collecting lens is evenly distributed with donut 2.1；As it is shown in figure 1, with
The cross section profile of heart annulus 2.1 is right angled triangle, and right-angle side is towards direction, the concentric circular center of circle.
As shown in Figure 4, the lower surface of collecting lens is evenly distributed with radial straight line 2.2, radial straight line to
In scope at interior annulus 2.5, the diameter of interior annulus 2.5 is equal to the smallest circle ring diameter of donut 2.1,
So, the vertical incidence part of light source is no need for the refraction through collecting lens.
As it is shown in figure 5, the zone cross-sectional between its adjacent radial straight line of the lower surface of collecting lens is middle
The symmetrical arc that high both sides are low, be can be seen that by edge wheel profile 2.3；Its horizontal stroke of the lower surface of described collecting lens
Cross section is that in the middle of the lower surface of the symmetrical arc that middle high both sides are low, i.e. collecting lens, high surrounding is low, is similar to
Convex lens.Described collecting lens uses buckle to install, and collecting lens edge is provided with claw 2.4.
Described collecting lens is made up of transparent material, and upper surface is fuzzy face.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that,
For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to
Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model
The protection domain of patent should be as the criterion with claims.
