Description
Technical field
The invention belongs to technical field of LED illumination, and in particular to the lens and lens group of a kind of plug-in unit LED lamp bead.
Background technology
In order that the luminous energy that LED chip is sent preferably is projected, it is utilized, and it is full in illumination region
Sufficient use requirement to LED, it is necessary to carry out Optical System Design.Wherein, the design in lamp bead encapsulation process is referred to as once light
Learn design；And the optical design carried out outside lamp bead encapsulation is referred to as secondary optical design, secondary light-distribution is also made to design.Once
Optical design is mainly decision LED lighting angle, light intensity magnitude, allocation of square etc.；Secondary optical design, which is mainly, allows lamp bead
Light focus in the illumination region of application.
It is many in current industry to coordinate secondary optical lens to reach application target using patch-type LED lamp bead.Paster LED lamp
The once light-distribution of pearl is similar to Lambertian, and plug-in unit LED lamp bead carries reflector due to inside, and its once light-distribution is fixed angle
Fusiformis, the lens of two kinds of lamp beads can not be general.The secondary light-distribution of paster LED lamp bead is mainly convergence, and Lambertian light source is sent out
The light gone out is converged in application region, and this is not appropriate for plug-in unit LED lamp bead.
It is existing not use secondary light-distribution to be only applied to plug-in unit LED lamp bead using the design of once light-distribution for problem above,
The document delivered mainly includes《A kind of LED street lamp based on the oval lamp bead of small-power》Utility model patent notification number
CN205424589U, patent of invention publication No. CN105156955A；《A kind of LED street lamp》Use new patent notification number
CN203349111U。
The deficiency of such a method is that light fixture does not carry out secondary light-distribution, it is impossible to light is applied to uses area to greatest extent
Domain, or even can not effectively be applied.For example the light fixture without secondary light-distribution is used as street lamp, and it can not meet《Road shines
Bright design standard》.
The present invention proposes a kind of plug-in unit LED lamp bead lens and lens group for problem above and deficiency.
The content of the invention
The invention aims to solve, the secondary light-distribution problem of plug-in unit LED lamp bead, and a kind of plug-in unit LED invented
Lamp bead lens and lens group.
The purpose of the present invention is achieved through the following technical solutions：
Including：Single lens（2）, it is hollow half ellipse entity, outside constitutes lens exit facet by Smoothing spline curved surface（7）, it is internal
Lens entrance face is constituted by smooth hemispherical curved surface（9）；Single lens（2）Inside is lamp bead accommodating cavity（8）, plug-in unit LED lamp bead
It is placed in one；A number of single lens（2）Pass through the array combination formation lens group of rule（1）；Lens group（1）With saturating
Microscope group mounting surface（6）And the lens group grab with other mechanism member assemblings（3）；Lens group（1）Lens with accommodating cable
Group cable accommodating cavity（4）；Lens group（1）Lens group water proof ring accommodating cavity with accommodating water proof ring（5）,（Such as Fig. 1,2,3,4）.
Plug-in unit LED lamp bead is placed in lamp bead accommodating cavity（8）Internal center and lamp bead top surface and lens entrance face（9）'s
Gap is no more than 0.5mm（Such as figure four）.
Lens entrance face（9）To lens exit facet（7）Lens component thickness be 0.5mm~2mm（Such as Fig. 3）.
Lens entrance face（9）It is consistent with the luminous face curvature of plug-in unit LED lamp bead, light is injected lens entrance face（9）When do not produce
Raw refraction,（Such as Fig. 4,5）.
Lamp bead accommodating cavity（8）The quantity for the plug-in unit LED lamp bead that inside is placed is 1（Such as Fig. 4）.
Lens group mounting surface（6）With lens group grab（3）For assemble mechanism, for being assembled with radiator.
Lens group（1）For makrolon or lucite material.
Beneficial effect
Present invention contrast prior art has following innovative point：
Plug-in unit LED lamp bead lens and lens group that the present invention is provided, the secondary light-distribution device designed exclusively for plug-in unit LED lamp bead,
The incident light of lens can more accurately be controlled by possessing the lamp bead accommodating cavity more matched with plug-in unit LED lamp bead；The lens thickness ratio
Conventional lenses are thin, are 0.5mm~2mm, and volume is smaller, and lens processing is more simple, and manufacturing cost is lower；Per in single lens
Containing a plug-in unit LED lamp bead, due to small volume, many lens forming closely spaced array lens groups, beneficial to mixed light, reduce glare；Institute
State lens and carry mounting surface with installing grab and waterproof ring recess, can directly be assembled with radiator without the use of screw；It is described
Mirror surface of emission surface is smooth, is difficult to hide dust, it is easy to clean, and certain cleaning effect is can reach under natural wind and rain drop erosion
Really, artificial cleaning operation is reduced, maintenance cost is reduced.
