Abstract
The invention discloses a centrally-packaged LED streetlamp PC lens module comprising a lens. The lens is provided with an inner cavity. The outer surface of the lens is composed of a concave upper surface, a convex left surface, a right surface, a front surface and a flat rear surface. The upper surface, the left surface, the right surface and the front surface are all free surfaces. The original glass streetlamp lens is replaced with the PC lens, a peripheral sloping flat plate is added, and the sloping flat plate is provided with uneven microstructure; accordingly, weight of the lens is reduced, the cost is reduced, and production process is simplified. Illumination utilization rate and uniformity of an LED streetlamp can be increased, so that illumination is free of dazzling.
Description
Technical field
The present invention relates to a kind of PC lens module of concentrated packaged LED street lamp.
Background technology
The lens that all concentrated packaged high-power LED street lamps are arranged in pairs or groups at present are all to use glass material to make, and the material of glass will be shaped, and needs at least above thickness of 10mm, and the size of raw bar material also can limit the size of lens.Due to above-mentioned restrictive condition, if the thickness of glass is too thick, can cause light absorption excessive, weight increases; If the too little meeting of lens sizes causes optical look angle to enlarge, and easily because lens are too small, produce larger dazzle.
Summary of the invention
Due to the problems referred to above of prior art, the present invention proposes, and it can effectively solve the problems referred to above of prior art.
The present invention addresses the above problem by the following technical programs:
A kind of concentrated packaged LED street lamp PC lens module, comprise lens, described lens inside is provided with a cavity, the outer surface of described lens is comprised of top-surface camber, the left curved surface of outwardly convex, right curved surface and front curve and the straight back plane of depression, and described top-surface camber, left curved surface, right curved surface, front curve are free form surface.
It is parallel with the bottom surface of described lens that described cavity is made as the major axis that a shape is 1/4th ellipsoids and this ellipsoid.
Described cavity top is greater than 40 millimeters apart from the height of the bottom of lens.
The design of described free form surface meets Snell law and uniform light type (cos θ)
-3the setting of parameter.
The periphery of described lens bottom stretches and forms the oblique flat board that a periphery is upturned to surrounding.
Irregular micro-structural is set on the bottom surface of described oblique flat board.
The two-end thickness of described oblique flat board is less than the thickness at the middle part of described oblique flat board.
Because adopting the PC lens, the present invention replaces the bare glass street lamp lens, increasing oblique flat board and tiltedly on flat board, setting up concavo-convex micro-structural simultaneously, can alleviate the weight of lens, reduce costs, simplify production technology, promote utilization rate, the uniformity of LED street lighting simultaneously, can reach the effect of free from glare illumination.

The specific embodiment
Below in conjunction with the specific embodiment, describe the present invention in detail.
Shown in Figure 1, concentrated packaged LED street lamp PC lens module of the present invention, comprise lens 1, described lens 1 inside is provided with a cavity 11, the outer surface 12 of described lens is comprised of top-surface camber, the left curved surface of outwardly convex, right curved surface and front curve and the straight back plane of depression, and described top-surface camber, left curved surface, right curved surface, front curve are free form surface.
The design of described free form surface meets Snell law and uniform light type (cos θ)
-3the setting of parameter.Utilize desired light distribution and calculate position and the tangent plane slope of curved surface, can construction come from by curved surface, last just can the construction free-form surface lens, and the design of free form surface is to calculate by the light distribution of needs the lens curved surface needed, but not general optical design, the mode Come construction lens of use Try and error.
It is parallel with the bottom surface of described lens that described cavity is made as the major axis that a shape is 1/4th ellipsoids and this ellipsoid.Shown in Figure 1, described cavity 11 tops are greater than 40 millimeters apart from the height H of the bottom of lens, can be because of near the LED lamp, causing excess Temperature and softening transform with the lens of guaranteeing the PC material.
Referring to shown in Fig. 2 to Fig. 4, the periphery of described lens bottom to surrounding stretch form that a periphery is upturned oblique dull and stereotyped 2.Tiltedly on the bottom surface of flat board 2, irregular micro-structural 3 is set.And the two ends 21 of described oblique flat board and 22 thickness are less than the thickness at described oblique dull and stereotyped 23 middle part.
Shown in Figure 4.Tiltedly extremely tiltedly flat board is upper by ray guidance for flat board 2 and concavo-convex micro-structural 3, can increase the effect of leaded light and bright dipping to reach the luminous effect of full wafer.Simultaneously, due to the effect of free form surface, will the luminous intensity fast-descending when the light penetrated surpasses 70 degree to zero, as shown in Figure 5A.
Material of the present invention is PC, in the process of manufacturing moulding, also need to add anti-UV material, the more existing glass of quality is gently a lot, can reduce the weight of lens module integral body, and Cost reduction.
Referring to Fig. 5 A and Fig. 5 B, be the luminous intensity distribution in the horizontal and vertical directions that has utilized lens of the present invention, visible lens of the present invention can promote the illumination utilization rate of LED, and visual angle is enlarged.
Should be understood that these embodiments only are not used in and limit the scope of the invention for the present invention is described.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
