Abstract
The utility model relates to an LED light-emitting device with double-layer lenses. The LED light-emitting device comprises a housing, an LED light-emitting chip, an inner-layer lens and an outer-layer lens, wherein the LED light-emitting chip is mounted on a substrate at the rear end of the housing; the outer-layer lens is mounted at the front end of the housing; the inner-layer lens is mounted between the LED light-emitting chip and the outer-layer lens through a fixing frame; the inner-layer lens is a convex lens; the outer-layer lens is a corrugated lens; and the centers of the LED light-emitting chip, the inner-layer lens and the outer-layer lens are on the same straight line. The shape elements of different LED light-emitting chips are matched and optically shaped by the convex lens and the corrugated lens so as to achieve the effects of clear drawing and boundary. The LED light-emitting device contributes to promotion of wider application of LED lamps, especially the application to road and tunnel illumination and motorcycle and automobile lamp illumination.
Description
Technical field
The utility model relates to a kind of LED light-emitting device, particularly a kind of double layer lens LED light-emitting device.
Background technology
In some use occasion such as automobile lamp, motorcycle lamp, the hot spot that needs light-illuminating to go out rear formation is sharp-edged rectangle, square or other shapes.And under the prior art situation, light is through the reflection of reflection shield, and the hot spot of formation is diversity, the hot spot edge blurry; Have portioned product to adopt convex lens that light is converged, the refraction through convex lens does not constitute sharp-edged hot spot yet, causes the light pollution outside the edge; Even adopt lighttight shadow shield edge to block, because halo effect, the edge of hot spot is also fuzzyyer, and because blocking the light efficiency that makes light source reduces, causes waste.
The utility model content
In order to address the above problem, the purpose of this utility model is for providing a kind of hot spot edge clear, light efficiency to utilize high double layer lens LED light-emitting device.
The purpose of this utility model is achieved in that a kind of double layer lens LED light-emitting device, comprise shell, LED luminescence chip, inner-layer lenses and outer layer lens, the LED luminescence chip is arranged on the substrate of rear end of shell, outer layer lens is arranged on the front end of shell, inner-layer lenses is arranged between LED luminescence chip and outer layer lens by fixed mount, described inner-layer lenses is convex lens, outer layer lens is the waveform lens, and LED luminescence chip, inner-layer lenses and outer layer lens three's center is on same straight line.
Described LED luminescence chip is on the focal position of inner-layer lenses.
Described LED luminescence chip can be monomer LED, can be also that two above monomer LED are spliced.
The little prism of described outer layer lens is the half tubular linear lens of cylinder that are equal to or less than of single face.
The utility model carries out the optical shaping of twice in use to reach good hot spot effect with two-layer lens and LED luminescence chip form fit.The internal layer of these lens is convex lens, make the original shape hot spot of LED luminescence chip obtain optimal clear amplification, again by the corrugated lens of outer field vertical line or band, again carrying out optical shaping through the light that amplifies for the first time after shape, to reach the graphical effect that widens or draw high after amplification.Because internal layer optically focused convex lens obtain optimal clear amplification to LED luminescence chip shape, again by the corrugated lens of outer field vertical line or band, carry out again the grid sheet and divide to be equipped with and reach the optical figuring that widens or draw high amplifying for the first time shape, can satisfy the needs of the many-sided different graphic of irradiation.
After adopting technique scheme, the utlity model has following advantage:
The utility model carries out the optical shaping of twice lens with convex lens and corrugated lens after to different LED luminescence chip shape element adapteds again, reaches the effect that figure is clear, the border is clearly demarcated.This utility model will help to promote the LED lamp and use more widely, the particularly application of highway, tunnel illumination, Motorcycle headlight, auto lamp illumination aspect, and realize the graphics shape energy-conservation, that controlled light is penetrated and reduce dazzle, reduce the aspects such as light pollution and make larger contribution to society.
Original LED luminescence chip shines on the internal layer convex lens with the most original shape, and convex lens amplify LED luminescence chip shape hot spot, then the shape after the corrugated lens of outer vertical line or band widens or draws high amplification.This device can the final graphical effect that needs of simple realization after twice lens light gathering.Lens Design and processing are more simple and be easy to realization, and controllability is strong.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is structural representation of the present utility model;
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing:
A kind of double layer lens LED light-emitting device, comprise shell 1, LED luminescence chip 2, inner-layer lenses 3 and outer layer lens 4, LED luminescence chip 2 is arranged on the substrate 6 of rear end of shell 1, outer layer lens 4 is arranged on the front end of shell 1, inner-layer lenses 3 is arranged between LED luminescence chip 2 and outer layer lens 4 by fixed mount 5, described inner-layer lenses 3 is convex lens, and outer layer lens 4 is the waveform lens, and LED luminescence chip 2, inner-layer lenses 3 and outer layer lens 4 threes' center is on same straight line.
Described LED luminescence chip 2 is on the focal position of inner-layer lenses 3.
Described LED luminescence chip 2 can be monomer LED, can be also that two above monomer LED are spliced.
The little prism of described outer layer lens 4 is the half tubular linear lens of cylinder that are equal to or less than of single face.
Certainly, above-described embodiment, it is preferred embodiment of the present utility model, be not to limit practical range of the present utility model, therefore all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model scope.
