The embodiment of the present invention provides a kind of lens, light source module and lighting device.
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
In prior art, lighting device all coordinates with lens due to each luminescence unit, and when needs change luminescence unit quantity, also need the quantity of accommodation lens, whole process wastes time and energy.The invention provides a kind of solve foregoing problems lens and corresponding light source module and lighting device, below in conjunction with accompanying drawing, aforesaid lens, light source module and lighting device are described in detail.
Shown in ginseng Fig. 1, light source module 10 comprises lens 11, luminescence unit 12 and substrate 13.
Lens 11 comprise main body 111, and main body 111 can be the such as transparent material such as polycarbonate, polymetylmethacrylate preparation, and luminescence unit 12 emitted light can penetrate lens 11 and arrive at region to be illuminated.
Preferably, lens 11 can be stretched by aforementioned transparent material one and make.
Main body 111 extends along extension axis L1, and extending axis L1 can be the common in the industry shape such as straight axis, arc axis, square ring axis, triangle axis or hexagon axis, also can be the combination of aforementioned shapes axis.
In the embodiment of the present invention, main body 111 has the vertical cross-section 1111 vertical with extending axis L1, and all identical in the shape of the vertical cross-section 1111 extending optional position on axis L1.
Such as, when to extend axis L1 be complete arc axis, because the form trait of vertical cross-section 1111 is consistent, then main body 111 also in one complete, along extending, axis L1 various piece is circular uniformly.
Receiving space 112 is formed at the bottom of main body 111, and it is enough large that the size of receiving space 112 is designed, and makes receiving space 112 can accommodate at least one luminescence unit 12.
Because receiving space 112 can accommodate at least one luminescence unit 12, when being arranged in the demand of luminescence unit 12 quantity that changes along extension axis L1, without the need to adjusting the quantity of lens 11 again, avoid in prior art the problem of the quantity of adjustment lens of wasting time and energy, improve the matching capacity of lens 11 pairs of varying number luminescence units 12.
Luminescence unit 12 can be the photophore of LED or other types, and this is technology well known to those of ordinary skill in the art, does not repeat at this.
For luminescence unit 12 for LED, can according to the standard size of most of LED element on the market, the size of customization receiving space 12, ensures that it can accommodate at least one luminescence unit.
In the embodiment of the present invention, receiving space 112 extends along extension axis L1, and the extended distance of receiving space 112 on extension axis L1 can adjust according to its size requirements.
Preferably, receiving space 112 is identical with the extended distance of main body 111 on extension axis L1, is convenient to receiving space 112 and accommodates luminescence unit 12 as much as possible, improve the illumination capability of light source module 10.
In the embodiment of the present invention, receiving space 112 is in the form of slot, to be positioned at bottom main body 111 and to make to have a notch bottom main body 111, and now, the vertical cross-section 1111 of main body 111 is in arch.Luminescence unit 12 can be mounted in receiving space 112 very easily from notch.Certainly, receiving space 112 is not limited to above-mentioned channel-shaped, can also be other Common Shape, be not repeated herein.
Shown in composition graphs 2, luminescence unit 12 is positioned on substrate 13, and lens 11 are also installed on the substrate 13; Substrate 13 can be printed circuit board (PCB), a flexible PCB etc., only needs to ensure that all luminescence units 12 are all electrically connected with providing the power supply module (not shown) of electric power.This power supply module can be jointly on the substrate 13 integrated with luminescence unit 12.
Because receiving space 112 is positioned at the bottom of lens 11, then all luminescence units 12 can enter in receiving space 112.
Substrate 13 is flat, makes substrate 13 to be mounted in lighting device very easily.
Preferably, substrate 13 also extends along extending axis L1, and the size of its substrate 13 is substantially identical with the bottom size of lens 11, make lens 11 install with substrate 13 together with have stronger globality afterwards, be convenient to the two integrally to use.When lighting device needs multiple light source module, light source module as herein described is diverted and installs, the expansion of light source module is also become easy.
Be still complete arc axis to extend axis L1, substrate 13 and lens 11 are also in circular.
In the embodiment of the present invention, lens 11 are dismountable to be mounted on substrate 13, is convenient to the quantity of user's fast assembling-disassembling lens 11 come adjustment luminescence unit 12.Wherein, lens 11 can adopt the quick-disassembly structures common in the industry such as fastening, chute to be connected with substrate 13, do not repeat at this.
Shown in composition graphs 3, main body 111 comprises incidence surface 1112 and exiting surface 1113, the incidence surface 1112 i.e. internal face of receiving space 112, peripheral surface relative with receiving space 112 internal face in exiting surface 1113 i.e. main body 111.
Luminescence unit 12 send and irradiate light and arrive incidence surface 1112 by air, then arrive exiting surface 1113 by transparent material in main body 111, finally enter thus among air, head for target area illumination.
In the embodiment of the present invention, incidence surface 1112 and exiting surface 1113 are curved, and vertical cross-section 1111 is in dome-shaped.
Certainly, in other embodiments of the present invention, incidence surface 1112 can also be irregular planar, is not limited to curved, does not repeat at this.
In the embodiment of the present invention, by adjusting the radius of curvature of incidence surface 1112 and exiting surface 1113, make incidence surface 1112 be configured such that luminescence unit 12 send irradiate light diffusion or converge, exiting surface 1113 be configured such that described luminescence unit send irradiate light diffusion or convergence.
Preferably, the radius of curvature of incidence surface 1112 is less than the radius of curvature of exiting surface 1113, then luminescence unit 12 send and irradiate light by after incidence surface 1112 and exiting surface 1113, lighting angle is strengthened, and is applicable to user and wishes that lighting device sends and irradiate the large scene of irradiation angle.
Certainly, in other embodiments of the present invention, the radius of curvature of incidence surface 1112 also can be greater than the radius of curvature of exiting surface 1113, then luminescence unit 12 send irradiate light by after incidence surface 1112 and exiting surface 1113, lighting angle is reduced, is applicable to user and wishes that lighting device sends the scene of irradiating light and converging.
In the embodiment of the present invention, vertical cross-section 1111 is zhou duicheng tuxing.For vertical cross-section 1111 for dome-shaped, vertical cross-section 1111 comprises axis of symmetry L2, and axis of symmetry L2 vertically extends towards substrate 13 from dome-shaped peak, and vertical cross-section 1111 is divided into two parts, and these two parts are relative to axis of symmetry L2 axial symmetry.
Certainly, vertical cross-section 1111 is not limited to aforementioned dome-shaped, and it can be the zhou duicheng tuxings such as such as square arch, annular.
Because vertical cross-section 1111 is relative to axis of symmetry L2 axial symmetry, and axis of symmetry L2 is perpendicular to substrate 13.Luminescence unit 12 send and irradiate light after lens 11 process, its illumination angle is also symmetrical relative to axis of symmetry L2.
