Abstract
The utility model discloses a luminous body based on secondary optics. The luminous body is mainly formed by a light-transmitting cover, a light-emitting diode (LED) luminous assembly arranged in the light-transmitting cover and an optical lens arranged on the outer surface of the light-transmitting cover. The luminous body has the advantages of solving the problem of low light-emitting efficiency by adding the secondary optical design and achieving the optical design aim of avoiding dazzling.
Description
Technical field
The utility model relates to the luminous heat radiation of LED, specifically is meant outdoor lighting products such as LED street lamp, garden lamp.
Background technology
Existing LED street lamp, garden lamp all are designed to standard E27, E47 interface, though install conveniently, if the bigger heat radiation of led light source power is inconvenient, radiating efficiency is not high.
Led light source need prevent that dazzle is to the eyes pessimal stimulation; Therefore glare filter must be installed; Mostly general glare filter is organic transparent or the bleach cover that the bleach material is made of acrylic (PMMA), polycarbonate resin (PC) or other modifications; Its common shortcoming is that light extraction efficiency is lower, has only scattered light, no secondary optics light distributing function.
The utility model content
The purpose based on the illuminator of secondary optics of the utility model design just is to increase the secondary optics design, and it is lower to solve light extraction efficiency, and reaches the optical design that prevents to produce dazzle.
The purpose of the utility model realizes through following technical proposals: based on the illuminator of secondary optics, mainly be made up of diffuser and the optical lens that is arranged on the inner LED luminescence component of diffuser and is arranged on the diffuser outer surface.
Said LED luminescence component mainly is made up of fixed mount and some illuminating parts of being arranged on the fixed mount outer surface.
Said fixed mount is cylindrical fixed mount, and said illuminating part is mainly by the bar shaped substrate and be arranged on the bar shaped substrate and constitute along the LED luminous tube that bar shaped substrate axis is " one " font array arrangement; Said bar shaped substrate is that center of circle circular array is arranged and is arranged on the outer wall of fixed mount with the central point of fixed mount.
Said optical lens is that the cross section is polygonal bar shaped prism.
Said optical lens is that the cross section is polygonal hollow bar shaped prism.
For the utility model, set up diffuser in LED luminescence component periphery or optical lens carries out the design of secondary optics.It is lower to solve light extraction efficiency with this, and reaches the optical design that prevents to produce dazzle.
Said diffuser be shaped as cylinder or circular cone or round platform.
Said optical lens is on the outer wall that is arranged in diffuser of center of circle circular array with the central point of diffuser.
Further, diffuser can be designed to cylinder or shapes such as circular cone or round platform, generally adopts cylindrical.When needs are regulated the beam projecting direction, can diffuser be designed to circular cone or round platform.Therefore optical lens cooperates with the profile of diffuser, and the side angle of diffuser is adjusted, and can adjust the transmitted light direction.
The design principle of the utility model is: undertaken luminously by the LED luminous tube in the secondary optics luminescence component, the direction of light scattering is 360 °, and this moment is not when adding the dazzle cover; Can produce glare phenomenon, set up existing glare filter, translucent effect is poor; Therefore; The utility model is provided with diffuser at the outer surface of illuminating part, after light sees through diffuser, is penetrated behind the dispersion effect of polygonal hollow bar shaped prism through the cross section again.Solve the problem of dazzle with this.Heat dissipation problem: the bar shaped substrate of the utility model is an aluminium base, and heat is passed to the fixed mount heat radiation through aluminium base with heat.
The advantage of the utility model is: increased the secondary optics design, it is lower to solve light extraction efficiency, and reaches the optical design that prevents to produce dazzle.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment one:
Shown in Fig. 1-6, the design principle of the utility model is: undertaken luminously by the LED luminous tube in the secondary optics luminescence component 2 26, the direction of light scattering is 360 °; Can produce glare phenomenon when not adding the dazzle cover this moment, sets up existing glare filter; Translucent effect is poor, and therefore, the utility model is provided with diffuser 22 at the outer surface of illuminating part; After light sees through diffuser 22, penetrated behind the dispersion effect of polygonal hollow bar shaped prism through the cross section again.Solve the problem of dazzle with this.Heat dissipation problem: the bar shaped substrate 24 of the utility model is an aluminium base, and heat is passed to fixed mount 25 heat radiations through aluminium base with heat.
As shown in Figure 1, based on the illuminator of secondary optics, mainly constitute by diffuser 22 and the optical lens 21 that is arranged on the inner LED luminescence component 23 of diffuser 22 and is arranged on diffuser 22 outer surfaces.
As shown in Figure 3, LED luminescence component 23 mainly is made up of fixed mount 25 and some illuminating parts of being arranged on fixed mount 25 outer surfaces.
Shown in Fig. 1-3, fixed mount 25 is cylindrical fixed mount, and illuminating part is mainly by bar shaped substrate 24 and be arranged on the bar shaped substrate 24 and constitute along the LED luminous tube 26 that bar shaped substrate 24 axis are " one " font array arrangement; Bar shaped substrate 24 is that center of circle circular array is arranged and is arranged on the outer wall of fixed mount 25 with the central point of fixed mount 25.
As shown in Figure 6, optical lens 21 is polygonal hollow bar shaped prism for the cross section.Seamed edge is arranged on the side away from diffuser 22.
Shown in Fig. 1-6, the utility model sets up diffuser 22 in LED luminescence component 23 peripheries or optical lens 21 carries out the design of secondary optics.It is lower to solve light extraction efficiency with this, and reaches the optical design that prevents to produce dazzle.
Diffuser 22 be shaped as cylinder.
Further, diffuser 22 can be designed to cylinder or shapes such as circular cone or round platform, generally adopts cylindrical.When needs are regulated the beam projecting direction, can diffuser 22 be designed to circular cone or round platform.Therefore optical lens 21 cooperates with the profile of diffuser 22, and the side angle of diffuser 22 is adjusted, and can adjust the transmitted light direction.
Embodiment two:
Embodiment two is with the difference of embodiment one: as shown in Figure 7, optical lens 21 is polygonal hollow bar shaped prism for the cross section.Seamed edge is arranged on the side near diffuser 22.
To sum up, just can realize the utility model preferably.
