Abstract
The utility model provides a light-emitting diode (LED) condensing lens and relates to the LED light source illumination field. The LED condensing lens comprises a finish coat. A cup-type body structure is arranged on one face of the finish coat, and a finish coat exit facet is arranged on the other face opposite to the cup-type body structure. An exit counter bore is formed in the exit facet. The exit facet of the finish coat is in a bead facet structure. Due to the structure, the LED condensing lens is even in light transmittance, large in illuminating range, high in brightness, and high in light transmittance rate. High requirements of intensity of illumination are met, the whole condensing lens is integrally manufactured, manufacture is easy and convenient, and project design is simple.
Description
Technical field
The utility model relates to the LED light source lighting field, is especially a kind of LED collector lens.
Background technology
Along with LED light source replaces conventional light source gradually, the advantage of LED lighting is day by day admitted by people, such as being used for field of street lamp lighting, LED replaces conventional lamp, the characteristics such as LED small volume and less weight, driving voltage is low, the life-span is long, efficient is high, vibration resistance, energy-conserving and environment-protective are for the illuminator that is designed for different places and purpose provides supremacy clause.People get used to seeing the thing under daylight, and for general illumination, people need is mainly light source near the sunshine quality.Traditional illuminating lamp adopts lampshade optically focused.Lampshade optically focused process be through lens again through a light shield optically focused, waste luminous energy and causes luminance shortage.The lighting angle intractability of conventional lenses is large, and the light projector degree is bad.Its uniformity and range of exposures all are difficult to satisfy under environment for use to going out the requirement of light effect.
Do not concentrate because the characteristics of luminescence of LED lamp makes light, therefore existing LED lamp is all adjusted light with lens.Light transmittance is not high when existing LED lens use, the inhomogeneous and problem such as brightness is not high enough, and angle design is unreasonable, and range of exposures is little of hot spot after printing opacity.
The utility model content
The technical problems to be solved in the utility model is the deficiency that after, printing opacity not high for light transmittance in above-mentioned prior art, hot spot is inhomogeneous and brightness is high not, and a kind of LED collector lens is provided, and makes that printing opacity is even and the large brightness of range of exposures is high, and light transmittance is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED collector lens, include the plane of incidence and exit facet, also include finish coat, finish coat simultaneously is provided with one glass of type body structure, the another side relative with cup type body structure is the finish coat exit facet, and exit facet is provided with an outgoing counterbore, is pearl face structure on the exit facet of finish coat.
Preferably, also be provided with a fixing step on described finish coat side, so that LED collector lens and external component are fixed.
Preferably, described cup type body structure is provided with an incident counterbore, is provided with a convex surface in the incident counterbore as the plane of incidence of light.
Preferably, described cup type body structure is that an end is provided with finish coat, and the other end is provided with the circular cone shape of incident counterbore.
Preferably, the pearl face structure of described finish coat exit facet is the Cellular Networks trellis.
The beneficial effects of the utility model are: the LED collector lens, in the incident counterbore and the convex surface that adopts of pearl face structure increase by light extraction efficiency, obtain the light of homogeneous and bright.Its glass type body structure can be collected the incident sidelight and reflect away, and obtains beautiful hot spot effect after making it to see through lens.Exit facet is designed to the cellular pearl face of grid structure, can make light soft, forms more various hot spot effect, reaches the illuminance requirements at the higher level.The making that is formed in one of its whole lens is made simple and conveniently, makes engineering design simpler.

Fig. 2 is that the LED collector lens is looked up structural representation, also shows the partial enlarged drawing of pearl face structure in figure.
Fig. 3 is LED collector lens cross section structure schematic diagram, also shows the partial enlarged drawing of pearl face structural profile in figure.
In figure: 1, finish coat 2, fixedly step 3, cup type body structure 4, outgoing counterbore 5, exit facet 6, incident counterbore 7, the plane of incidence
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to figure 1, Fig. 2 and Fig. 3, a kind of LED collector lens, include the plane of incidence and exit facet, also include finish coat 1, finish coat 1 one side is provided with one glass of type body structure 3, the another side relative with cup type body structure 3 is finish coat 1 exit facet, and exit facet is provided with an outgoing counterbore 4, is pearl face structure on the exit facet of finish coat 1.
Also be provided with a fixing step 2 on described finish coat 1 side, so that LED collector lens and external component are fixed.Described cup type body structure 3 is provided with an incident counterbore 6, is provided with a convex surface in incident counterbore 6 as the plane of incidence 7 of light, incident counterbore 6 and outgoing counterbore 4 sizableness.The interior ray cast angle of described incident counterbore 6 is 45 degree.Described cup type body structure 3 is that an end is provided with finish coat 1, and the other end is provided with the circular cone shape of incident counterbore 6.The pearl face structure of described finish coat 1 exit facet is the Cellular Networks trellis, is a crowning in grid.The pearl face structure of the interior exit facet 5 in described outgoing counterbore 4 is honeycomb grid dress, is a crowning in grid.The LED collector lens of the PMMA material that described a kind of LED collector lens is optical grade or the LED collector lens of PC material.
After LED lens light gathering lens and the contraposition of LED lamp, the LED lamp is placed in lens incident counterbore 6.The LED lamp is placed in lens and utilizes the fixedly step 2 on finish coat 1 sidewall to be connected with other outer relay parts, makes accurate and firm being fixed on outer relay part of lens, more is conducive to normal work.After the LED lamp emits beam by reflection occurs by the several times full-reflection spotlight after the plane of incidence 7 optically focused in lens incident counterbore 6 in cup type body structure 3, the formation scope is obvious and concentrated, penetrate light in the cellular crowning of grid of the interior exit facet the outgoing counterbore after the higher light beam of brightness from finish coat 1, make light soft, form more various hot spot effect.Cup type body structure 4 is conducive to the collection of light, has increased the lightness of light.
The above is not that this novel technical scope is imposed any restrictions, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
