Abstract
The invention discloses a light emitting diode (LED) lamp, which comprises an LED array, a lampshade and a concave lens arranged between the LED array and the lampshade, wherein the light emitting surface of the LED array is positioned within a virtual focusing point of the concave lens. Compared with the prior art, the LED lamp has the advantage that soft light rays can be acquired.
Description
Technical field
The present invention relates to lighting device, particularly relate to a kind of LED lamp.
Background technology
Led light source is exactly that light emitting diode (LED) is the light source of illuminator, and it has efficient height, long characteristics of life-span, is becoming the main product of illumination.
But in commercial general lighting with family expenses was used, because LED luminous energy is too concentrated, human eye usually was difficult to stand the high light of its generation, presses for its luminous energy is disperseed homogenize, obtains soft illuminating ray.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of industrial cost low, the even good LED lamp of light effect.
Technical problem of the present invention is solved by the following technical programs:
A kind of LED lamp comprises led array and lampshade, also comprises the concavees lens that are arranged between described led array and the described lampshade; Wherein, the light-emitting area of described led array is positioned within the virtual focus of described concavees lens.
In order to obtain further even light effect, grating layer can also be set in lampshade or pass through site die mould technology at formation rule or the irregular pit in lampshade surface.
The lampshade surfaces externally and internally is done frosted handle, also can be so that light is softer.
The present invention compared with prior art adopts concavees lens that the light that led array sent is dispersed and expands bundle, and the LED light that makes luminous energy concentrate scatter, thereby can obtain soft illuminating ray.
Description of drawings
Fig. 1 is the structural representation of led array of the LED lamp of the specific embodiment of the invention;
Fig. 2 is the structural representation of the LED lamp of the specific embodiment of the invention;
Fig. 3, Fig. 4 are the structural representations of two kinds of lampshades of the specific embodiment of the invention.
The specific embodiment
The preferred specific embodiment of contrast accompanying drawing and combination is explained in detail the present invention below.
LED lamp of the present invention comprise led array, lampshade and be arranged on described led array and described lampshade between concavees lens; Wherein, the light-emitting area of described led array is positioned within the virtual focus of described concavees lens.
As shown in Figure 1, the led array 1 of present embodiment is a LED paster array of source, and each LED axially-aligned becomes the lamp strip.
As shown in Figure 2, the concavees lens 3 of present embodiment are the bicylindrical spherical lens, and the light-emitting area of led array 1 is positioned on the virtual focus of these concavees lens 3; Lampshade 3 is used to cover led array and concavees lens 3, and it can adopt various optical materials commonly used.In the practice, these concavees lens 3 also can adopt single-column face lens, and whether lens are that spherical lens also can be selected according to actual needs; The light-emitting area of led array can be arranged within the virtual focus of concavees lens 3, promptly can be also can be between this virtual focus and concavees lens 3 on the virtual focus of concavees lens 3.
For obtaining better even light effect, as shown in Figure 3, can make grating layer at the inner surface and/or the outer surface of lampshade, or adopt the lampshade of the sandwich construction that comprises grating layer; As shown in Figure 4, also can be by the surperficial formation rule or the irregular pit of site die mould at lampshade.
The lampshade outer surface of present embodiment has also carried out the frosted surface treatment, so that emergent ray is softer.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some being equal to substitute or obvious modification, and performance or purposes are identical, all should be considered as belonging to protection scope of the present invention.
Claims (6)
