Problems solved by technology

However, there is a limit to how high the reflected light can hit (e.g. from ground level)
In addition, improved lighting and glare control of modern lighting fixtures, especially LED lighting fixtures, can disadvantageously attenuate uplighting as downlighting is highly aimed at the field and provides adequate but not excessive "ground level" uplighting in the "flight zone" (Spaces above ground) little or no upward lighting is provided in reflected lighting areas
At the same time, trying to increase the upward light can produce undesired glare due to the intensity of the LED lighting

Embodiment Construction

[0032] background

[0033] In general, if the light source is diffuse, it will hardly be seen as an accurately positioned (less diffuse) source. LEDs used for area lighting such as sports lighting are generally regarded as relatively harsh light sources because they are close to the source point (as opposed to many or most other sized or wide-area light sources). Therefore, devices and methods for diffusing LED illumination are desirable. Hickcox et al. (Hickcox published on Lighting Research and Technology on February 20, 2013, "Effect of different coloured luminoussurroundson LEDdiscomfortglareperception" by K et al. (lightingRes.Technol.2012; 0:1-12), the full text of which is incorporated herein by reference) has confirmed , Surrounding LED lights with luminous sources that contribute some measurable part of all the light seen by the viewer can significantly reduce glare. Their experiment uses a separate light source ("semi-cylindrical light box acting as an integrated cham...

Abstract

An apparatus, system and method for glare reduction and effective lighting, including uplighting for such things as sports fields including golf courses or for other large area projects. A set of solid state light sources having an original perceived intensity from viewers and an original light output, are altered to be perceived by a viewer as a larger light source to reduce glare to the viewer. This alteration can occur when a number of techniques including diffusive or reflective surfaces in the original output of the light sources. Altered light output is further modified by either cutting portions of it off or redirecting portions of it for more effective use. For example, a visor with reflective surface can redirect light either to a target area or for uplighting. This allows concurrent benefits of glare reduction for viewers of the sources or effective use of light.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Provisional Application No. 61 / 825,370 filed on May 20, 2013 under 35U.S.C.§119 / 35U.S.C.§120, the entire application of which is incorporated herein by reference. Technical field [0003] Some embodiments of the invention relate generally to lighting systems. More specifically, some embodiments of the present invention relate to LEDs and other solid state lighting fixtures and devices. Background technique [0004] LEDs are becoming increasingly popular in sports and wide area lighting, but there are also concerns. One concern is the intensity of the LED lighting when the viewer is watching. To understand the importance of this concern, it is necessary to understand how to irradiate a target area such as a stadium. Any target area requires a certain amount of light to fall on it. This light can come from a precisely located source, such as one or more LEDs, or it can come from a...
