Abstract
The utility model relates to the field of optical lenses, in particular to a combined type LED optical lens. The combined type LED optical lens comprises a plurality of unit lenses, and each unit lens comprises an inner lens surface and an outer lens surface. The inner lens surfaces are concave faces, and the outer lens surfaces are convex faces. The inner lens surfaces are matched with a light source, the outer lens surfaces are free-form surfaces, and a light distribution curve of the combined type LED optical lens is in a batwing type. The combined type LED optical lens improves the light use ratio and is rapid and convenient to install. After light distribution is carried out on the LED light source through the combined type LED optical lens, glare can not be caused to influence vehicles or pedestrians in the distance, an outgoing facula of the LED light source is a rectangular and evenly-distributed facula, and the city roadway lighting design standard is met.
Description
Technical field
The utility model relates to the optical lens field, particularly a kind of combined LED optical lens.
Background technology
In order to meet the Lighting Design of Urban Road standard, traditional road illuminating lamp often adopts power consumption mercuric bulb more than 200 watts.By contrast, by 2009, the optical efficiency of light emitting diode on market (LED) surpassed 100lm/W, this means the street lamp that adopts LED to make light source, and its power consumption will reduce greatly.Due to the extra long life of LED, mercurous and not energy-conservation characteristic, the street lamp that adopts LED to make light source replaces traditional LPS(low-pressure sodium lamp) or the MH(metal halide lamp) be good selection.At present, the LED street lamp in the world every country all test.In order to solve the emission problem of energy scarcity and greenhouse gases, the LED street lamp is practical in some places, and wherein some areas and the urban government in China, North America and Europe have carried out positive popularization.
Because the LED major part of dispatching from the factory on market is all to be youth uncle type to distribute, central light strength is more intense, and is that symmetrical circular light spot distributes, and causes dazzle can for vehicles or pedestrians at a distance, can not be directly used in road lighting.
Summary of the invention
Cause the technical problem of dazzle to vehicles or pedestrians at a distance in order to solve the LED street lamp, the utility model proposes a kind of combined LED optical lens, comprise a plurality of single-element lens, each single-element lens comprises inner lens surfaces and lens outer surface; Described inner lens surfaces is concave surface, and described lens outer surface is convex surface; Described inner lens surfaces coordinates with light source, and described lens outer surface is free form surface; The distribution curve flux of described combined LED optical lens is the bat aerofoil profile.
A kind of combined LED optical lens of the present utility model,, because LED light source is placed in the single-element lens inner surface, shine directly into road surface after refraction, reduced the consume of reflector to light, improved the utilization rate of light; A plurality of single-element lens are combined, and are easier for installation quick; LED light source after a kind of combined LED optical lens luminous intensity distribution of the present utility model, causes dazzle can for vehicles or pedestrians at a distance, and its outgoing hot spot is a rectangle, equally distributed hot spot, meets the Lighting Design of Urban Road standard.
Description of drawings
Fig. 1 is the structural representation of a kind of combined LED optical lens of the utility model embodiment 1.
The specific embodiment
Describe a kind of combined LED optical lens of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment 1
As shown in Figure 1, a kind of combined LED optical lens of the present utility model, comprise a plurality of single-element lens 1, and each single-element lens comprises inner lens surfaces and lens outer surface; Described inner lens surfaces is concave surface, and described lens outer surface is convex surface; Described inner lens surfaces coordinates with light source, and described lens outer surface is free form surface; The distribution curve flux of described combined LED optical lens is the bat aerofoil profile.
As shown in Figure 1, a kind of combined LED optical lens of the present utility model can also be provided with waterproof groove 2.When a kind of combined LED optical lens of the present utility model is installed, waterproof groove 2 is equipped with the water-proof silica-gel circle, can effectively prevent entering of sealing, dust etc.
As shown in Figure 1, a kind of combined LED optical lens of the present utility model can also be provided with wiring position groove 3, thus the assembling of convenient a kind of combined LED optical lens of the present utility model, airtight LED light source better.
