Detailed description of the invention

For making this utility model solve the technical problem that, the technical scheme that uses and the technique effect that reaches more Clear, further illustrate technical side of the present utility model below in conjunction with the accompanying drawings and by detailed description of the invention Case.

Embodiment 1

Refer to Fig. 1 to Fig. 3, present embodiments provide a kind of integral LED module lens, including entirety Lens 1 and several monomer lens 2 integrated with overall lens 1, overall lens is located at by monomer lens 2 The inner side of 1 and inwardly protruding, monomer lens 2 are boss shape.Module lens is one-body molded, it is no longer necessary to often Separately installed monomer lens 2 on individual LED, greatly simplifie packaging technology, improve efficiency, and boss shape Monomer lens 2 there is optically focused effect, can preferably distribute the light that LED sends.

The shape of monomer lens 2 is only required to be boss shape, and concrete shape can have multiple, boss The bus of side can be straight line or curve.When bus is straight line, boss can be round platform or terrace with edge； When bus is curve, can be the curve of evagination, can be further the camber line of evagination, preferably distribute The light that LED sends.The side of monomer lens 2 can also be scale face, and scale face refers to and non complete symmetry Kick shape, likeness in form scale Irregular Boundary Surface.Scale face can preferably divide light-distribution LED to send, And it is attractive in appearance.

For ease of preferably coordinating with LED, the end of monomer lens 2 is provided with the cavity volume for accommodating LED 21.LED in the application can be LED lamp bead, it is also possible to being SMD LED, LED puts into appearance After in chamber 21, the light that LED sends out spills module lens hardly, more light can be carried out secondary and divide Join, it is thus achieved that preferably optical effect.The shape of cavity volume needs to design according to the actual requirements, may be hemispherical, The difformities such as bowl-type, it is also possible to be combined with other materials, to obtain more preferably reflection or transmission effects. LED wall wash lamp is linear modulation, therefore, arranges at least two monomer lens 2 and is arranged in a linear at overall lens The inner side of 1, depending on the quantity of monomer lens 2 is by actual optics product demand, typically can use 3～6 in Linear array is one group, and the distance between each monomer lens 2 is also determined, respectively by actual optics product demand After group is mutually combined, different optical articles demands can be met.

In the present embodiment, the back of overall lens 1 is provided with groove 11, and monomer lens 2 are arranged on groove 11 In, by arranging groove 11, the end of monomer lens 2 can be beneficial to the back of non-bulging overall lens 1 The back of overall lens 1 is arranged on remaining part.Optionally, the medial wall of groove 11 is provided with striped 12, the light at the edge of overall lens 1 is allocated by striped 12 further, improves the optics of module lens Effect, and more attractive.The left surface of overall lens 1 and right flank can be plane or cambered surface.Left surface and the right side When side is plane, processing is simple, and the striped of the medial wall of fit 11, can preferably by light from Sidepiece distributes；When left surface and right flank are cambered surface, during the cambered surface of especially indent, further will be from The light that the striped 12 of the medial wall of groove 11 distributes, to external diffusion, has more preferably optical effect, the most beautiful See.

Module lens is when actually used, it is often necessary to polylith module lens is combined, therefore, by entirety The front end face of lens 1 and rear end face are set to the plane being parallel to each other, the rear end face of previous piece of module lens with The front end face of rear one piece of module lens can combination time cooperate, fit completely, do not have gap and The phenomenon of light leak, it is ensured that the module lens optical effect when combination.Further, can be saturating by entirety The front end face of mirror 1 and rear end face are disposed as the plane perpendicular with the front of overall lens 1, coordinate more preferably, Vertically disposed end face is less through impact during two end faces on light, and the impact on optical effect is less.Existing Have in technology, after monomer lens 2 are installed and adjustment completes, last installed surface glass sheet, both protected inside Monomer lens, the most more attractive.In the present embodiment, the front of overall lens 1 is set to tabular, substitutes Face glass, it is no longer necessary to separately installed face glass, further simplified assembling process.Optionally, overall The front of lens 1 is provided with striped, or the front of overall lens 1 is pearl face, and pearl face refers at overall lens 1 Surface configuration have a lot of kick being similar to the globule, the light in overall lens 1 can be broken up further, carry High optical effect, and increase the aesthetic of overall lens 1.The front of overall lens 1 can also be minute surface, Directly the light in overall lens 1 is projected away.Overall lens 1 and monomer lens 2 be PC material or PMMA material integrated molding.The heat stability of PC or PMMA, optics are special through characteristic, electric insulation Property and impact resistance the highest, meet demand, and processing technique be simple, low cost.In order to the most fixing Module lens, is evenly equipped with fixing hole 13 in the both sides of overall lens 1, and the both sides stress of overall lens 1 is equal Even.

Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, depends on According to thought of the present utility model, the most all will change, this explanation Book content should not be construed as restriction of the present utility model.
