Description
Technical field
This utility model relates to the technical field of a kind of LED, especially a kind of eye protection LED daylight lamp.
Background technology
In illumination market, daylight lamp is mainly based on fluorescent lamp at present, energy-conservation due to LED light source in recent years, and environmental protection is long-lived
Life, the advantage such as high efficiency, make employing LED as the daylight lamp of light source rapidly as the succedaneum of conventional fluorescent.But these are two years old
This shortcoming and deficiency is all there is in kind of daylight lamp product in lighting environment:
The shortcoming of conventional fluorescent: be first to have stroboscopic effect, generally 50/60HZ, this effect is to human eye spinosity
Swash effect, eyestrain can be made for a long time under the luminous environment with stroboscopic, be easily caused or trigger ocular disease.The most traditional
Fluorescent lamp light efficiency is low, and typically not over 60lm/W, in the case of meeting general lighting, power consumption is the biggest；Conventional fluorescent
Lamp color rendering index is the lowest, is so difficult to, by this chromatic rendition of photographed object, make object color be difficult to distinguish.It addition, conventional fluorescent
Lighting angle be 360 °, the light having most angle to issue in illumination applications needs could apply through secondary reflection
On face to be illuminated, and light can be made to be absorbed by such secondary reflection thus reduce system light efficiency, make illuminating effect reduce.
Although LED daylight lamp energy-conserving and environment-protective, but while replacing conventional fluorescent, also produce a series of negative shadow
Ring.Important is a little that LED luminescence has directivity, and as LED daylight lamp, its lighting angle the most also only has 180 ° of left sides
The right side, is difficult to accomplish 360 ° of luminescences as conventional fluorescent, although so improve lamp system light efficiency (by direct for more light
Act on photographed object), but too increase the light intensity of light fixture dazzle angular direction simultaneously, thus produce dazzle.
Its reason is exactly in the case of meeting equal luminous flux, and due to the reduction of light-emitting area, the light intensity of its light-emitting area increases
Adding, thus increase dazzle, it addition, it is few to be also due to LED daylight lamp light distribution on 180 ° of horizontal planes, causing cannot
There is enough light to be irradiated to light fixture back (ceiling or ceiling and wall), so can cause LED daylight lamp and background (ceiling
Or ceiling and wall) form obvious bright dark contrast, also result in discomfort glare, the most conventional work in such a case
Work learns, and can cause visual fatigue, and particularly in teaching environment, luminous source too strong in space not only results in dazzle, and
And visual direction can be induced, and take sb's mind off sth, impact teaching and study.
Utility model content
In lighting environment, direct glare is produced with uncomfortable in order to solve LED daylight lamp present in above-mentioned prior art
The problem of dazzle, by structural manufacturing process and three luminous intensity distribution technology in LED pipe footpath, it is provided that a kind of eye protection LED daylight lamp.
This utility model solves its technical problem and be the technical scheme is that
A kind of eye protection LED daylight lamp, includes LED, substrate, radiator, lampshade, drives power supply, lamp holder；Print on substrate
Being brushed with one layer of tin cream, the surface soldered of substrate has LED, and LED forms loop；Substrate is provided with pad, and pad passes through wire
It is connected with the outfan driving power supply, drives the input of power supply to be connected with lamp holder Electricity Federation；The substrate of LED be placed on be provided with recessed
On the radiator of groove, and insert in the lampshade being provided with draw-in groove；Substrate, radiator and lampshade two ends are combined together, with fastening spiral shell
Nail or glue in one, form complete LED daylight lamp by fixing to lamp holder and lampshade；The inner surface uniformly continuous of lampshade is arranged with

This utility model also has a following additional technical feature:
Optimizing further, the light of LED daylight lamp is launched via after once light-distribution, secondary light-distribution and three luminous intensity distributions；
Once light-distribution is Lambertian, and during lamp holder energising, the once light-distribution type of LED is Lambertian；Secondary light-distribution be once light-distribution it
After light can be through the internal arc-shaped cover of lampshade, through transmission, refraction and diffuse-reflectance, light can be radiated at the outside of lampshade uniformly
On arc-shaped cover；Secondary light-distribution, for spreading the lighting angle of LED self, is diffused into 180-240 ° by 90-120 °；Three luminous intensity distributions
Luminous intensity distribution is carried out through lampshade outer cup part for light after secondary light-distribution；Three luminous intensity distributions will be divided into three parts to light:
Key lighting part, dazzle angle part and background illumination area；Key lighting part, in LED daylight lamp hexagonal angle degree vertically downward
Area of light, by LED self luminescence realized by lampshade transmission；Dazzle angle part, arrives horizontal plane beyond primary illumination zone
Region, is obtained through outside three luminous intensity distributions of lampshade after being broken up by secondary light-distribution by LED again, utilize light inside lampshade
Refraction by prism changes light, and the part light distribution in 120 ° of regions of LED daylight lamp is transformed to primary illumination zone and background illumination
Region；Background illumination area, is used for improving background luminance, reducing LED daylight lamp light-emitting area and background luminance difference and reduce because sending out
The discomfort glare produced when bright finish and background luminance differ greatly, is broken up through three luminous intensity distributions by after LED secondary optics again
After obtain.
Optimize further, drive power supply to be used for transformation constant current, after the upper contact pin energising of lamp holder, through power supply of overdriving
Transformation constant current, can make LED light.
Optimizing further, substrate is glass fibre basal plate.
Optimize further, the surface uniform application Heat Conduction Material Graphene of radiator.
Optimizing further, the material of lampshade is the one in acrylic, polystyrene, Merlon, polypropylene material.
