Description
Technical Field
The invention relates to a reflection-type anti-glare LED lamp which is mainly used in indoor and outdoor illumination places needing unidirectional low-glare light.
Background
With the development of lighting technology, the standard of glare in various occasions is more and more strict, particularly UGR (Unigraphics) is required to be less than 16 in classroom lighting, and the traditional fluorescent lamp or LED lamp cannot meet the standard due to overhigh surface brightness and needs to be added with anti-dazzle treatment;
the existing anti-dazzle in the market is mostly in a mode of adding an anti-dazzle device on a light-emitting surface. The anti-dazzle device is mainly divided into a diaphragm and a grid, the anti-dazzle effect of the diaphragm is general, the basic effect is UGR 16-19, the absorption rate is high, the lighting effect of the lamp is low, finally the LPD (light-emitting diode) for overall illumination exceeds the standard, and the energy-saving advantage of the LED is basically lost; the anti-dazzle grid effect is superior to that of a diaphragm, basically ranges from UGR 14 to UGR16, the optical efficiency is higher than that of the diaphragm, and finally the lamp efficiency ranges from 70lm/w to 90lm/w, which is superior to that of a fluorescent lamp by 50 lm/w to 70 lm/w; in order to adapt to new applications and high-standard application scenarios, lamps with higher light quality need to be developed.
The traditional fluorescent lamp is a surface light source, as shown in fig. 1, the traditional fluorescent lamp comprises a flat lamp shade 1 and an LED light source assembly 4, light emitted by the LED light source assembly 4 is partially emitted from the lower side directly, and partially emitted from the lower side after being reflected by the lower surface of the flat lamp shade 1, so that people can directly see the LED light source assembly 4, and the glare is easy to occur. Moreover, most of the optical systems are reflective, the whole system is large in size, but the brightness is low, and the glare of the lamp is moderate. The LED is an approximate point light source, the brightness is concentrated, the existing optical system light mixing mostly adopts a lens or diffusion light mixing, the lens can realize accurate light control, the application is mature in small-angle projection, but the brightness is high, and strong glare can be avoided only by proper installation; while diffuse mixing is mainly in indoor lighting, indicating low brightness and moderate overall glare, the efficiency is much reduced due to diffusion material absorption. With higher energy saving standards and anti-glare requirements, better optical systems are required to be developed.

In the reflection-type anti-glare LED lamp, the inner surface of the arc-shaped lampshade 2 is the reflecting surface 5, the anti-glare grid plate 3 is connected between two side edges of the bottom opening of the arc-shaped lampshade 2, light emitted by the LED light source assembly 4 irradiates the reflecting surface 5, and the reflecting surface 5 can enable the light to be uniformly distributed and uniformly emitted from the grid holes 7. Thus, the light emitted from the light source is not directly emitted from the grid holes 7, and people do not directly see the LED light source through the grid holes 7, so that the light can be prevented from being locally concentrated to generate glare.
In the reflection-type anti-glare LED lamp, the anti-glare grid plate 3 can partially shield and reflect light again so as to make the light be distributed as uniformly as possible. In order to enable the grid holes 7 on the antiglare grid plate 3 to be more uniform, please refer to fig. 2 and 4, the grid holes 7 extend in the width direction of the antiglare grid plate 3. Therefore, the grid holes 7 are large in number and uniform in distribution, and light is uniformly distributed. In order to partially reflect light and prevent people from directly seeing local glare on the LED light source or the arc lampshade 2 to reduce glare, the partition plate 6 is inclined relative to the vertical direction as a preferred embodiment. Thus, people cannot easily directly see the reflecting surface 5 of the arc lampshade 2, part of the light emitted from the light source is directly emitted from the grid holes 7 after being reflected by the reflecting surface 5, the other part of the light is irradiated on the partition plate 6, and the light is finally emitted from the grid holes 7 after being reflected by the partition plate 6. Therefore, the light can be distributed more uniformly after being reflected for many times, and people are not easy to directly see local strong light of the reflecting surface.
In a preferred embodiment, the surface of the partition plate 6 is provided with a mirror coating or a frosting treatment. This facilitates light reflection by the partition plate 6 or makes the light distribution more uniform.
