Patent Application
20170227193
The present invention relates generally to lighting systems, and more particularly to a modularized luminaire providing for a high degree of precise lighting in a limited space.
In lighting glare may be caused by the contrast between bright and dark lighting. For example, if only 1 luminaire is installed in a room, the occupants may sense significant glare, whereas if multiple luminaires are installed the glare will be reduced. Glare can be reduced or eliminated by adding shields (or baffles) to the luminaires to direct the light to reach a desired affect.
Disclosed herein is a device comprising a circuit board, said circuit board having a plurality of LEDs dispose on said circuit board, and a chassis, said chassis having a plurality of baffles, each baffle formed by bending a portion of the chassis substantially orthogonally to the surface of the chassis leaving a plurality of holes in said chassis, said holes spaced substantially the same spacing as the plurality of LEDs. The baffles may operate to shield light emitted from the LEDs to either 30 degrees, 45 degrees or 60 degrees. Also included is a housing operable to secure the circuit board and chassis into a fixed position.
The construction and method of operation of the invention, however, together with additional objectives and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings
Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
In some embodiments the baffles 118 may have different colored surfaces to modulate the reflection of light from the light sources out of the luminaire. Also a dust cover 124 may be employed to protect the light source or modulate the amount of light. An aluminum, or other suitable, housing 120 for supporting the LED board 112 and the dust cover 124 may be employed.
References in the specification to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure or characteristic, but every embodiment may not necessarily include the particular feature, structure or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one of ordinary skill in the art to affect such feature, structure or characteristic in connection with other embodiments whether or not explicitly described. Parts of the description are presented using terminology commonly employed by those of ordinary skill in the art to convey the substance of their work to others of ordinary skill in the art.
In operation, the spacing (or density) of the LEDs and the height of the microlouvers operate to effect certain light patterns. While
One having skill in the art may effectuate many optical patterns, e.g. from the diffraction and reflection effects of varying the height, color and material of construction, of the louvers in relation to the LED spacing. In certain embodiments, louvers of different height, color and material of construction, may be employed to allow for placement of luminaires in different environments. In some embodiments, louvers of different height, color and material of construction, may be employed to allow for placement of luminaires in an environment. Using the shielding angle as an example and without limitation, a luminaire may be created having a 30-degree light radiation pattern on one portion and a 60-degree light radiation pattern on another portion, to create a specific illumination pattern, resultant from the effects of the combination.
The above illustration provides many different embodiments or embodiments for implementing different features of the invention. Specific embodiments of components and processes are described to help clarify the invention. These are, of course, merely embodiments and are not intended to limit the invention from that described in the claims.
Although the invention is illustrated and described herein as embodied in one or more specific examples, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
This application is a divisional of and claims the benefit of co-pending application Ser. No. 13/940,225 filed Jul. 11, 2013 which further claims the benefit of then pending provisional patent application 61/671,018 entitled “Micro Louver,” filed on Jul. 12, 2012 by the same inventor, both of which are incorporated into this document by reference as if fully set forth herein.
