Abstract

A polarization cup relates to a lens for an LED lamp and comprises a cup body. The cup body is frustum-shaped, the cross section which is perpendicular to the height of the cup body is rectangular, four corners of the rectangular cross section are filleted, the inner surface of the cup body is divided into a plurality of frustum-shaped ring layers, the height direction of each frustum-shaped ring layer is parallel to that of the cup body, each ring layer form a frustum-shaped reflecting unit surface, the top and the bottom of each frustum-shaped reflecting unit surface are in arc-shaped transition to form an arc-shaped surface, an electroplated reflective film with extremely high light reflectivity is plated on the inner surface of the cup body, and a positioning groove which is used for mounting an LED bulb and positioning a mounting direction of the LED bulb is manufactured on a base. Light rays are projected in a rectangular manner, irradiation distance along the length direction of a road is increased, illumination quality of the road is improved, the light rays are projected uniformly, light spots are prevented, polarization cups are manufactured into single small parts and can be combined easily to form lamps with different powers, the reflective film is plated on the inner surface of the cup body, the problem of optical loss due to ageing of a lens is solved, and the service life of a product is prolonged.

Description

The polarisation cup

Technical field

The utility model relates to the lens that are used for the LED lamp, refers to the polarisation cup especially.

Background technology

Along with led light source replaces conventional light source gradually, the advantage of LED lighting replaces conventional lamp day by day by people's approval such as LED being used for field of street lamp lighting, can bring many superiority such as improving light efficiency, energy-saving and environmental protection.

But present most LED street lamps are radiated at hot spot on the road surface for circular, also differ greatly with the actual requirement of the length direction uniform irradiation along the road surface.Perfect condition is: sprawl as much as possible along link length direction glazed thread; And can be controlled effectively at road width direction glazed thread; Uniformity with the illumination that improves the road surface; Thereby make the road surface that better illumination brightness arranged, reduce, can reduce the waste of luminous energy in addition as far as possible because of the underlit traffic accident that causes.

What on the LED lighting, use at present is the plastic cement secondary lens, very big to the quality influence of illumination, different lens designs, and transparent materials with different, plastic cement is along with the increase of service life can be worn out, and light transmission efficiency descends, and the light loss consumption increases.Updating the lens design is to improve one of importance of LED street lighting effect.

Summary of the invention

The utility model is intended to overcome the above-mentioned deficiency of prior art, and meeting the market requirement provides a kind of polarisation cup, and it is used for the LED illuminating lamp.Its characteristics: the rectangular shape of projection shape of (1) hot spot scatters, ray cast angle 60 * 120 degree, and light concentrates on the road surface; (2) the illumination projection is even, no hot spot; (3) make single little individuality, can carry out aggregate erection with a plurality of, make Design of Luminaires simpler, be easy to be combined into the light fixture of different capacity, (4) have solved the aging light loss consumption that causes of lens, increase service life of the products.

For this reason, the technical scheme of the utility model polarisation cup is following:

The utility model polarisation cup comprises cup, and said cup is taper type, the big end of its taper type and be the outlet of the light path of opening wide, the handle of its taper type and for the pedestal of light emitting diode is installed; Become four angles of rectangle and this rectangle to become the rounding horn shape with the high vertical cross section of said cup; Said cup inner surface is divided into the ring layer of a plurality of taper types; The short transverse of the said ring layer of taper type is along the direction of the height of said cup; Each said ring layer forms a taper type reflecting unit face, is that arc-shaped transition is to form the A arcwall face at the two end of said taper type reflecting unit face; Said cup inner surface is coated with the reflective membrane high to light reflectance; The system opened on the said base is used to the locating slot LED lamp pearl being installed and locating LED lamp pearl installation direction, is all the B arcwall face and bloats to the both sides at the cell wall along the both sides of the center of its flute length of said locating slot, and LED lamp pearl is installed wherein.

Technique scheme is further set forth:

Said B arcwall face is the semicircle curved surface.

Drive the system deep-slotted chip breaker in one side of said B arcwall face and make locating slot have elasticity, so that LED lamp pearl is installed.

On cup, also be shaped on the cup shoulder that installs and fixes usefulness, the convex edge that said cup shoulder protrudes out for the big bottom of taper type cup laterally.

The curvature of the arcwall face that forms at the two end of said taper type reflecting unit face be complementary as the light emitting diode of light source.

Cup adds the ABS material with plastic cement PC.

The beneficial effect of the utility model is: one of which, the rectangular projection of light that the reflection back is penetrated increases along the distance of shining on the link length direction, and the road lighting quality is improved.Its two, illumination projection evenly, no hot spot.Its three, make single little individuality, can carry out aggregate erection with a plurality of, make Design of Luminaires simpler, be easy to be combined into the light fixture of different capacity; Its four, adopt huge shape cup, in the design of inner surface plating reflective membrane, solve the aging light loss consumption that causes of lens, increase service life of the products; Its five, locating slot can conveniently be installed LED lamp pearl and locate LED lamp pearl installation direction.

The specific embodiment

Below, introduce the specific embodiment of the utility model in conjunction with accompanying drawing.

To shown in Figure 5, the utility model polarisation cup comprises cup 1 like Fig. 1; The appearance of cup 1 is a cup outer surface 2, is cup inner surface 7 in the

cup

1,1 one-tenth taper type of said cup; The big end of its taper type and be the outlet of the light path of opening wide, the handle of its taper type and for the pedestal of LED lamp pearl is installed; Become four angles of rectangle and this rectangle to become the rounding horn shape with the high vertical cross section of said cup 1; Said cup inner surface 7 is divided into the ring layer of a plurality of taper types; The short transverse of the said ring layer of taper type is along the direction of the height of said cup 1; Each said ring layer forms a taper type reflecting unit face 4, is that arc-shaped transition is to form the A arcwall face between two ends of said taper type reflecting unit face 4; Said cup inner surface 7 is coated with the reflective membrane 8 high to light reflectance; The system opened on the said base is used to the locating slot 6 LED lamp pearl being installed and locating LED lamp pearl installation direction, is all B arcwall face 3 and bloats to the both sides at the cell wall along the both sides of the center of its flute length of said locating slot 6, and LED lamp pearl is installed wherein.
