Abstract
The utility model provides a novel structure for improving light transmittance of a lens. The technical scheme includes that a reflecting layer is coated around a conical portion on the later surface of an existing lens and under the lens, so that lights of lamp beads can be more effectively guided out from the top of the lens according to expected design angles, and the light transmittance is greatly increased.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED lamp of high light-emitting rate.
Background technology
Light emitting diode (hereinafter being called LED) industry is as a kind of emerging rising industry, obtained sufficient application in various luminous lightings field, especially in the recent period the development of LED technology makes the LED luminous efficiency be greatly improved, and therefore favored by illumination market.
Therefore the light extraction efficiency of LED light fixture is the important indicator of light fixture performance, how better to improve the light extraction efficiency of light fixture, and be needs the subject matter considered always in the Design of Luminaires.Common light fixture lens are the bright structure of full impregnated at present, and light transmittance is probably about 85%.In order to improve the lens light emission rate, use the higher material of light transmittance usually instead in the traditional design, but the increase of light transmittance also is very limited, and the price between the different light transmittance material also differs very huge.Common lens material is the bright plastics of full impregnated, and lamp pearly-lustre line major part derives from the lens top by the desired design angle, and small part is inevitably sent by around the lens, is common light leakage phenomena, and the existence of light leakage phenomena has seriously reduced the light emission rate of lens.
The utility model content
At above problem, the utility model provides a kind of lamp pearly-lustre line that can make all to derive from the lens top by the desired design angle, improves the new construction of lens light emission rate.
The utility model is achieved through the following technical solutions.
A kind of new construction that improves the lens light emission rate, comprise base, be fixed in the lamp pearl on this base, also comprise cone and the lens that are connected with this cone, described cone base is provided with the lamp hole of bead, described cone is set on the lamp pearl by this lamp hole of bead, and described cone inner surface is coated with the reflecting layer.
Further, described reflector thickness is 0.2mm.
Further, described lens and described cone are tightly connected.
Further, described lens are the printing opacity shape.
Further, described base is an aluminium base.
The beneficial effects of the utility model and advantage.
A kind of new construction that improves the lens light emission rate that the utility model provides, be coated with the reflecting layer at the following pyramid type of original lens side surface lens position around circular cone one circle, make lamp pearly-lustre line more effectively to derive, light transmittance is significantly improved from the lens top by the desired design angle.
Description of drawings
Fig. 1. a kind of structural representation that improves the new construction of lens light emission rate described in the utility model.
Fig. 2. a kind of structure broken away view that improves the new construction of lens light emission rate described in the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is carried out describing in detail in the present embodiment below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1 and Fig. 2, the utility model provides a kind of new construction that improves the lens light emission rate, comprises base 5, is fixed in the lamp pearl 4 on this base 5.
Also comprise cone 2 and the lens 1 that are connected with this cone 2, described cone base is provided with the lamp hole of bead 3, and described cone 2 is set on the lamp pearl 4 by this lamp hole of bead 3, and described cone 2 inner surfaces are coated with the reflecting layer.
Described cone first-selection is a cone.
The reflecting layer that described cone 2 inner surfaces are coated with, the material of plating can for aluminize, reflective metallic material such as silver-plated, nickel plating, zinc-plated, chromium plating.
The above reflector thickness is to be 0.1mm to 0.5mm, is preferably 0.2mm.
The above lens 1 is tightly connected with described cone 2.
The above lens 1 is the printing opacity shape.
The above base 5 is an aluminum substrate.
The above only is preferred embodiment of the present utility model, not in order to the restriction utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
Claims (5)
1. new construction that improves the lens light emission rate, the lamp pearl that comprises base, is fixed in this base, also comprise cone and the lens that are connected with this cone, described cone base is provided with the lamp hole of bead, described cone is set on the lamp pearl by this lamp hole of bead, it is characterized in that described cone inner surface is coated with the reflecting layer.
