The LED condensing lens comprises an incidence surface, an existing surface and a cup-shaped structure, wherein one end of the cup-shaped structure is provided with the existing surface, the other end of the cup-shaped structure is provided with a counter bore, the existing surface is of a bead surface structure, and the edge of the existing surface is provided with an assembling step. According to the structure, the lens is even in light transmission, large in lighting range, high in luminance, and high in light transmittance, and achieves high requirements of illuminance, the whole lens is formed in an integrated mode, manufacture is simple and convenient, and engineering design is simple.
Description
Technical field
The utility model relates to the led light source lighting field, especially is the 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 the daylight, and for general illumination, people need mainly is 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 the environment for use to going out the requirement of light effect.
Because the characteristics of luminescence of LED lamp is not so that light is concentrated, 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 behind the printing opacity.
The utility model content
The technical problems to be solved in the utility model is the deficiency that hot spot is inhomogeneous and brightness is high not behind, the printing opacity not high for light transmittance in the above-mentioned prior art, and the LED collector lens is provided, so that printing opacity is even and the large brightness of range of exposures is high, light transmittance is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: the LED collector lens, include the plane of incidence and exit facet, also comprise a glass type body structure, cup type body structure one end is provided with exit facet, the other end is provided with counterbore, is pearl face structure on the exit facet, and its exit facet edge also is provided with the assembling step.
Preferably, described assembling step is stepped and is higher than the plane at exit facet place, so that LED collector lens and external component are fixed.
Preferably, described cup type body structure is circular cone shape.
Preferably, the pearl face structure of described exit facet is the Cellular Networks trellis.
The beneficial effects of the utility model are: the LED collector lens, incident counterbore convex surface interior and that pearl face structure adopts increases by light extraction efficiency, obtains 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.
Description of drawings
Fig. 1 is LED collector lens perspective view.
Fig. 2 is that the LED collector lens is looked up structural representation, also shows the partial enlarged drawing of pearl face structure among the figure.
Fig. 3 is LED collector lens A-A cross section structure schematic diagram among Fig. 2, also shows the partial enlarged drawing of pearl face structural profile among the figure.
Among the figure: 1, cup type body structure 2, counterbore 3, the plane of incidence 4, exit facet 5, assembling step
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, the LED collector lens includes the plane of incidence and exit facet, also comprise a glass type body structure 1, cup type body structure 1 one ends are provided with exit facet 4, and the other end is provided with counterbore 2, be pearl face structure on the exit facet 4, its exit facet 4 edges also are provided with assembling step 5.
Described assembling step 5 is stepped and is higher than the plane at exit facet 4 places, so that LED collector lens and external component are fixed.Described cup type body structure 1 is provided with a counterbore 2, is provided with a convex surface in the counterbore 2 as the plane of incidence 3 of light.Further again, described counterbore 2 interior ray cast angles are 40 degree.Described cup type body structure 1 is that an end is provided with exit facet 4, and the other end is provided with the circular cone shape of counterbore 2.The pearl face structure of described exit facet 4 is the Cellular Networks trellis, is a crowning in the grid.The LED collector lens of the PMMA material that described 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 places in the lens counterbore 2.The LED lamp places lens to utilize the assembling step 5 on exit facet 4 edges to be connected with other outer relay parts, so that accurate and firm being fixed on the outer relay part of lens more is conducive to normal work.The assembly bench component level is in the edge of exit facet in addition, and its position is higher than exit facet, therefore assembles the illumination range that step 5 can be controlled light preferably.After the LED lamp emits beam by reflection occurs by the several times full-reflection spotlight behind the plane of incidence 3 optically focused in the lens counterbore 2 in cup type body structure 1, the formation scope is obvious and concentrated, from the cellular crowning of the grid of exit facet 4, penetrate light behind the higher light beam of brightness, so that light is soft, form more various hot spot effect.Cup type body structure 1 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.
