A gobo is a stencil or template placed inside or in front of a light source to control the shape of the emitted light. Lighting designers typically use them with stage lighting instruments to manipulate the shape of the light cast over a space or object—for example to produce a pattern of leaves on a stage floor.

The invention relates to a light source for lighting organic electroluminescence (OEL) plants. In the method, a light-conversion-light function layer is added to the outer surface of a glass substrate of an OEL light source, so that a part of incident light of the OEL light source transmitting the light-conversion-light function layer is converted into red light with wavelength of 600-680nm. The manufacturing method of the light source for lighting the OEL plants refers to manufacture the light-conversion-light function layer with hollow patterns on the outer surface of the glass substrate. In the invention, a light-conversion-light array is utilized to regulate the emitting proportion of a blue light peak area to a red light peak area of an organic light-emitting diode (OLED) lighting device, thus realizing an approximately-even area source.

Lighting applications which are particularly difficult to light because of “non-standard” target area characteristics or the like would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has reached a point of diminishing returns in terms of beam control. Envisioned is an LED lighting system designed for precision lighting insomuch that—as compared to state-of-the-art LED lighting fixtures—sharpness of cutoff is improved while in at least some cases simultaneously allowing a steeper cutoff without undesirable beam shift. Furthermore, overall beam dimensions can be tailored fixture-to-fixture for an application without replacing an entire optic system or designing an entirely new fixture, and control of intensity distribution is improved (e.g., by avoiding striations at the edge of beam patterns). Said envisioned LED lighting system employs a number of materials not used in conventional LED lighting systems in novel ways to achieve the aforementioned.
