Abstract

A 7*4 array polarizing LED street lamp module lens relates to a lens used for LED lamps. The 7*4 array polarizing LED street lamp module lens is a plate-shaped body and comprises a bottom surface and a top surface, wherein the top surface is opposite to the bottom surface. Concave pits where LED lamps are installed are disposed in the bottom surface. The concave pits are arranged in a 7*4 array manner. The surfaces of the concave pits are incident planes for the module lens. Polarizing bodies which are one-to-one corresponding to the concave pits are manufactured, and the surfaces of the polarizing bodies of the top surface are emitting planes for the module lens. The beneficial effects are that: with the incident planes and the emitting planes in the abovementioned structure, a light emitting angle of 85*135 DEG is formed, and then uniform rectangular light with a projection angle of about 60*120 DEG is formed on the rode surface, an irradiation distance along a length direction of a road is increased, and thus road illumination quality is improved; luminous energy waste is little as light is irradiated to areas where illumination is needed; and a plurality of modules can be designed and installed in a combination manner while illuminance is relatively high.

Description

A kind of LED street lamp module lens of 7 * 4 array polarisations

Technical field

The utility model relates to the lens that are used for the LED lamp, refers to a kind of LED street lamp module lens of 7 * 4 array polarisations 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.

The secondary lens that uses on the LED lighting is very big to the quality influence of illumination, and different lens designs produces different illuminating effects.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, meeting the market requirement, provide a kind of four row seven row polarisations LED street lamp module lens.Its characteristics: its characteristics: the one, the rectangular shape of projection shape of hot spot scatters, ray cast angle 85 * 135 degree, light concentrates on the road surface; The 2nd, the illumination projection is even, no hot spot; The 3rd, a plurality of low-power LED sheets are concentrated on the lens, realize modularity production, how much power of light fixture is regulated through module.

For this reason, the technical scheme of the LED street lamp module lens of a kind of 7 * 4 array polarisations of the utility model is following:

The LED street lamp module lens of a kind of 7 * 4 array polarisations of the utility model are a plate body, comprise bottom surface and the end face relative with the bottom surface; On the bottom surface, be shaped on confession LED and be installed on the pit in it, said pit forms 7 * 4 arrays, and the surface of said pit is the plane of incidence of the LED street lamp module lens of these a kind of 7 * 4 array polarisations; The respective production polarizing body is as the surface of said end face one by one with said pit, and the surface of said end face is the exit facet of the LED street lamp module lens of these a kind of 7 * 4 array polarisations.

Technique scheme is further set forth:

Open the seal groove that system supplies to install usefulness, sealing groove semicircular in shape on the cross section on four limits, upper edge, bottom surface.

On end face, be shaped on the screw hole that supplies to install usefulness, and this screw hole pierces the bottom surface.

Said plate body is made with transparent material, like PC etc.

The beneficial effect of the utility model is: one of which; Adopt the plane of incidence and the exit facet of said structure; Form the beam projecting angle of 85 * 135 degree; Just obtained the even rectangular light of a projectional angle about 60 * 120 degree on the road surface, increased, the road lighting quality is improved along the distance of shining on the link length direction.Its two, irradiate light is in the zone of needs illuminations, the luminous energy waste is few.Its three since adopted 4 * 7 totally 28 low-power LED luminous tube arrays install, the heat radiation of light fixture is better controlled, and can be designed to a plurality of modules for illuminance when higher and carry out aggregate erection, makes engineering design simpler.

The specific embodiment

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

To shown in Figure 5, the LED street lamp module lens of a kind of 7 * 4 array polarisations of the utility model are a plate body 1 like Fig. 1, comprise bottom surface 6 and the end face 2 relative with bottom surface 6; On bottom surface 6, be shaped on confession LED and be installed on the pit in it, said pit forms 7 * 4 arrays, and the surface of said pit is the plane of incidence 7 of the LED street lamp module lens of these a kind of 7 * 4 array polarisations; Respective production polarizing body 3 is as the surface of said end face 2 one by one with said pit, and the surface of said end face 2 is the exit facet 4 of the LED street lamp module lens of these a kind of 7 * 4 array polarisations.

The seal groove 5 that system supplies to install usefulness, sealing groove 5 semicircular in shape on the cross section are opened in four limits, 6 upper edges in the bottom surface.

On end face 2, be shaped on the screw hole that supplies to install usefulness, and this screw hole pierces bottom surface 6.

Said plate body 1 usefulness transparent material is made, like PC etc.

The above only is the preferred embodiment of the utility model, is not that the technical scope of the utility model is done any restriction.The technical staff of the industry; Under the inspiration of present technique scheme; Can make some distortion and revise, every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme above any modification, equivalent variations and modification that embodiment did.
