Description

A kind of LED street lamp lens module

Technical field

The utility model relates to LED street lamp field, is specifically related to a kind of LED street lamp lens module.

Technical background

Along with the LED application technology is perfect, the popular feelings is also progressively goed deep in the application of LED street lamp, because the field settings of LED street lamp application is abominable relatively; Long-term exposes to the sun and rain, and exposes to wind and rain, and the test that faces is extremely harsh; Be exactly the uniformity of light in addition; Extensive angle, high illumination has directly influenced the traffic safety of road, and the waterproof of street lamp and luminous intensity distribution are day by day paid close attention to.

The utility model content

The utility model provides a kind of LED street lamp lens module, solved the problem of water proof and dust proof on the street lamp, strengthen LED street lamp service life, reduce maintenance expense; And the luminous intensity distribution scheme of solution LED street lamp, the illuminating ray that gives way is more even, and angle is wider.

A kind of LED street lamp lens module is processed by transparent PC, and described LED street lamp lens module makes up up and down with the ladder form, is divided into upper strata lens jacket and lower floor's fixed bed; Described upper strata lens jacket comprises lens, left shielding layer, screw shielding layer, lens reinforcement; Described lower floor has offered the screw fixing hole in the fixed bed front, and the groove that caves in of waterproof apron is offered in the bottom, and the groove that wherein caves in has comprised outer shroud groove and the interior ring groove that caves in that caves in; The outer shroud groove that caves in has improved degree of protection on the one hand; Be exactly to reduce material on the other hand, be easier to disposable drawing, inside grooves is trapezoidal to extending below to fall and interior ring caves in; Realize better fitting with the trapezoid projection in the bottom.

As improvement, described lens are that circular left printing opacity cup and right printing opacity cup makes up to intersect mode; The intersection of the bottom of described lens offers the inner fovea part that is used to place LED lamp pearl, and said inner fovea part is an indent ellipticity.

As improvement, described left shielding layer (4) is the protruding square high platform of left end, and better the design protection circuit increases LED lamp pearl longer service life.

As improvement, described screw shielding layer is that 6 millimeters frosted rounded face is formed by a plurality of diameters.

As improvement, place one on the intersection location that described lens reinforcement is per two lens, strengthen the tough of the transparent module of LED street lamp on the one hand, improve third dimension on the other hand.

As improvement, the number of described lens is the even number more than 10 or 10, because convenient different application scenario, different height increases lens and improves terrible rate better.

As improvement, designed the groove that caves in of placing waterproof apron, the described groove that caves in comprises outer shroud groove and the interior ring groove that caves in that caves in, the described outer shroud groove that caves in is square inner groovy, serves as that rule distributes and comes on the outer shroud at interval with the screw locating hole; Encircling the groove that caves in described is to empty to extending below with taper, and its bottom is protruding ladder landing platform.

As improvement, described M4 screw fixing hole and M3 screw fixing hole front are convenient to flat head screw and are developed LED street lamp lens module all to offer conical socket.

The utility model beneficial effect is following:

1, one-shot forming lens, the angle of increase secondary light-distribution has been strengthened the light uniformity to distribution curve flux, for degree of protection provides the foundation.

2, reduce material on the other hand, be easier to disposable drawing, and the interior ring inside grooves of caving in being trapezoidal to extending below to fall, realizes better fitting with the trapezoid projection in the bottom.

Fig. 2 is the structural representation of the bottom of the utility model LED street lamp lens module;

Fig. 3 is the profile of the utility model LED street lamp lens module;

Fig. 4 is the distribution curve flux figure of the utility model LED street lamp lens module.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation:

The utility model said LED street lamp lens module such as Fig. 1, Fig. 2, shown in Figure 3: the said LED street lamp lens module of being processed by transparent PC is processed by transparent PC: described LED street lamp lens module makes up up and down with the ladder form, is divided into upper strata lens jacket (1) and lower floor's fixed bed (2); Described upper strata lens jacket (1) comprises lens (3), left shielding layer (4), screw shielding layer (5), lens reinforcement (6); M4 windage screw fixing hole (7) and M3 screw fixing hole (8) has up and down been offered in described lower floor fixed bed (2) front, and the groove that caves in (14) of waterproof apron is offered in the bottom.Because lens (3) are for aspheric surface designs, two identical hemisphere make up middle microprotrusion; Fit with oval inner groovy (12) and lamp pearl in the bottom, favourable light refraction, and secondly lens (3) are arranged in parallel; With limit, room, roadside balance, light obtain compound with strengthen, on the highway with the batswing tab shape distribution curve flux irradiation of symmetry; Distribution curve flux as shown in Figure 4, rising angle is wide, uniform.

The said LED street lamp lens of the utility model module has designed the groove that caves in (9) of placing waterproof apron; The described groove that caves in comprises outer shroud groove (13) and the interior ring groove (14) that caves in that caves in, and the described outer shroud groove (13) that caves in is square inner groovy, is the interval with the screw locating hole; Rule distributes and comes on the outer shroud; Encircling the groove (14) that caves in described is to empty to extending below with taper, and its bottom convexity is ladder landing platform (15), and wherein outer shroud caves in and strengthened degree of protection when groove (13) is avoided damaging by pressure except protection LED street lamp lens module; When interior ring caves in groove (14) when adding waterproof apron; Ladder landing platform (15) encircles groove (14) inwall that caves in to plane cushion rubber compressive strain, better tightness in the form applying with gradient.

The number that the said LED street lamp lens of the utility model module has designed lens (3) is the even number more than 10 or 10 because as shown in Figure 4, distribution curve flux with wide-angle; Gao Liang; Uniform presented, and illumination and luminous flux and distance are proportional, the difference in the application scenario; Highly different can have illumination to choose in the standard of 25-35 lux.

The utility model passes through simple in structure, the design of combined and instant, hommization outward appearance, integrated LED street lamp lens module.What stress at last is, the utility model is not limited to above-mentioned embodiment, has also comprised the luminous intensity distribution parameter that it is inner, with and respective outer side edges.
