Ceiling lamp lens type, specification and Application
发布者： 发布时间：10/05/14
preface:
1．This paper focused on ceiling lamp mainly adopts high power LED light source and its supporting the use of ceiling lamp lens, other than using LED as light source ceiling lamp or no lens on Ceiling lamp is not listed here.
2．ceiling lampare mainly used for indoor decoration lighting, mounted on the top surface of ceiling windows, counter top, used for indoor or local lighting effect of rendering, commodity exhibition and indoor illumination light supplement. In resource shortage advocate environmental protection and energy conservation ,today, using LED as light source days lantern with its electricity saving, long service life, small size and other characteristics is to replace the traditional tungsten halogen lamps and metal halide lamps light the ideal, it will gradually become the mainstream consumer market.
ceiling lamp lens of different LED spec.
一，ceiling lamp lens of different LED spec.
1.ceiling lampappearance specification is withФ86x65xH70mm, withФ105x87xH80mm, withФ135x110xH70mm
2.because of appearance specifications and power requirements are different, so the number of ceiling lamp LED are different, there are common 3 *1W, 5 *1W, 7 *1W, 12* 1W etc.;
3the ceiling lampusing several LED corresponds to several lens;
The ceiling lampusing several LED corresponds to several lens;
一，The single lens of ceiling lamp
1.if ceiling lampusing a lens, generally lens of ceiling lanternsdiameter is less than 36mm to, or they may be in the lens body on the basis of the increase of the surface of the lens size, so the lens and theceiling lampshall be installation and coordination each other;
2.if lens of ceiling lampusing a plurality of individual lens, the lens diameter is 15mm, 20mm or22mm
2.if lens of ceiling lampusing a plurality of individual lens, the lens diameter is 15mm, 20mm or22mm
二，lens module
1．in the same substrate ( the same material integrally molded ) surface in accordance with LED in aluminum plate of the consistent position and distribution of the corresponding LED lens, this integrated ceiling lens is also called LED lens module
2．in the same diameter of the substrate, it can be any of a plurality of lens and anyarrangement relations
3．in the assembly when installing the lens module is very convenient and time-saving
lens of ceiling lamp in different circumstances and requirements, it must be a different angle
一.Ceiling lamp mount in different places
1．The top surface of ceiling ,windows and counter, their irradiation heightare not the same
2．different irradiation area, so lens of ceiling lampcondensation angle is also different;
3．the several angle of ceiling lampis 25 degrees,38 degrees, 45 degrees, 60 degrees etc.;
2．different irradiation area, so lens of ceiling lampcondensation angle is also different;
3．the several angle of ceiling lampis 25 degrees,38 degrees, 45 degrees, 60 degrees etc.;
二，Irradiation distance and the irradiated surface luminance relation
1.in the same irradiation distance, when condensation angle is narrow ,irradiated surface luminance will be relatively high;
2.conversely, while condensation angle is wide as the irradiated surface luminance will be lower;
lens of ceiling lampsurfacetechnology
clear surface
1．Rate of penetration of clear surface lens is high , light loss is less;
1．Rate of penetration of clear surface lens is high , light loss is less;
2．because the LED technology is different, some LED in conjunction with light cleansing lens, beam will produce a yellow circle, just because of the main powder fired caused by uneven, when the lens have a small angle, yellow circle is more obvious;
3．the LED belongs to semiconductor light source, it has not yet reached the natural light of softness, so the light of ceiling damp will be dazzling;
二．frosting surface and edns array
1．the entire surface or the partial surface oflens can be completed through a special optical process in the mold.
2．by the optical matte surface treatment , it will diffuse the light mixing light again, so the beam is more uniform, light and soft,it is not to hurt the eyes
3．this process on the surface of relative can reduce some light effect, light loss is about 5%, but also depends on different manufacturers with different precision process and have different optical loss value, if the process is not good, it had lost more than 20%;
4．narrowing many times ,the ledns array get frosting surface, conversely, it is same Principle, so the two optical effect is almost, relative to the optical frosted surface ,light mixing processing is more delicate, so thefaculawould be more uniform
