A kind of light emitting diode optical collector

Technical field

The utility model relates to and is applied to the LED light fixture, particularly a kind of light emitting diode optical collector be applied in the LED light fixture.

Background technology

Optical collector in current most of LED light fixture, adopt non-spherical surface design reflective surface, and the optical collector light-emitting window becomes the garden hot spot into ellipse light spot with Fresnel Lenses, due to the restriction of Mould Machining, light gathering efficiency is not high, causes the light sent easily to disperse, the light losing rate is high, and brightness is not high.In addition, the relevant position of LED light emitting diode and optical collector is by fixed L ED light emitting diode and optical collector lens barrel location, and the mismachining tolerance of lens barrel affects the relevant position of LED light emitting diode and optical collector, produces rigging error, and light gathering efficiency descends.

The utility model content

The utility model proposes a kind of light emitting diode optical collector, be applied in the LED light fixture, collected light preferably, utilization rate is high; Structural design is ingenious, makes its light sent form oval hot spot and meets the actual illumination needs, and the LED light fixture illuminates higher.

The technical solution of the utility model is achieved in that

A kind of light emitting diode optical collector, be characterized in, described optical collector lateral surface is non-spherical reflecting face, core is cylindrical hole, the top of described cylindrical hole arranges convex lens, and described optical collector upper surface is a V-type groove, and described optical collector lower surface is provided with two positioning cylinders.

Above-mentioned optical collector upper surface is a V-type groove, the summit of described V-type groove is on the optical collector center line, the light that light emitting diode sends is reflected through the aspheric surface reflective surface, the circular hot spot of core convex lens transmission, by the refraction of V-type groove inclined plane, change the beam projecting angle, form oval hot spot, meet the actual illumination needs.

Further, described optical collector end face is regular hexagon, and described orthohexagonal two limits are parallel with the V-type groove, are convenient to fixedly optical collector.

The lower surface of described optical collector is provided with two positioning cylinders, during installation, inserts in the locating hole of aluminium base of diode light emitting diode and optical collector accurate positioning.

The beneficial effects of the utility model are, these lens are applied in the LED light fixture, and brightness is high, and glow color is even, energy-conservation, low in energy consumption, and light decay is low, the life-span is long, environmental protection, safe, pollution-free.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 2 is top view of the present utility model.

Fig. 3 is side view of the present utility model.

In figure, 1, the optical collector upper surface, 2, the optical collector lower surface, 3, convex lens, 4, the aspheric surface reflective surface, 11, the V-type groove, 21, positioning cylinder.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.

With reference to Fig. 1, a kind of light emitting diode optical collector, described optical collector lateral surface is non-spherical reflecting face 4, core is cylindrical hole, the top of described cylindrical hole arranges convex lens 3, described optical collector upper surface 1 is a V-type groove 11, and the summit of V-type groove 11 is on the optical collector center line, and there are two positioning cylinders 21 optical collector lower surface 2.

The V-type groove 11 that the utility model arranges by optical collector upper surface 1, the light that light emitting diode sends is reflected through aspheric surface reflective surface 4, the circular hot spot of core convex lens 3 transmission, by the 11 inclined plane refractions of V-type groove, change the beam projecting angle, form oval hot spot, meet the actual illumination needs, and collected light preferably, utilization rate is high, and the light that the LED light fixture sends is higher.

The utility model is by two positioning cylinders 21 that optical collector lower surface 2 arranges, and is inserted in the locating hole of aluminium base of diode light emitting diode and optical collector accurate positioning.

The curved surface of the convex lens 3 that arrange in above-mentioned cylindrical hole meets certain requirements: major semiaxis Y and semi-minor axis X, and Y, X relation meet following the requirement:

$y=\frac{\frac{1}{3.7}*x^2}{1+\sqrt{1+0.9*{\frac{1}{3.7}}^2*x^2}}$

The convex lens of this curved surface degree are collected in the zone of irradiating with making luminous energy higher proportion that light emitting diode sends, and the brightness that the LED light fixture is sent is higher.

The utility model is by arranging convex lens 3 and being arranged to doubling curved surface 11 at the end face of convex lens in lens, make the light that diode sends after convex lens 3, form oval hot spot, and collected light preferably, utilization rate is high, and the light that the LED light fixture sends is higher.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
