SUMMARY OF THE INVENTION
2009 naming the same inventors.
[0008]
FIELD OF THE INVENTION
[0002] The present invention relates to a combination light
ing and audio communication system for use in ceilings and
Walls, and more particularly to a modular system for provid
ing both light and sound in a commercial suspended ceiling
panel system.
BACKGROUND OF THE INVENTION
[0003] It is Well knoWn in the art to use various types of
incandescent and ?uorescent light sources for residential and
commercial buildings, mounting them into a ceiling tile or
dryWall type ceiling or Wall. Light sources are provided in
either surface mounted or recessed con?gurations, and in the
case of recessed mountings the housings can be cylindrical,
square or rectangular. The square and rectangular light
sources can be siZed for mounted directly into ceiling grids
Where no cutting of tiles is required.
[0004] There have been recent developments Which utiliZe
loW voltage or Light Emitting Diode (LED) sources in place
of the traditional incandescent and ?uorescent lights. These
LED arrays are smaller in physical siZe With a nearly ?at
pro?le, lending themselves to loW ceilings With limited ple
num space or even loW pro?le surface applications. The LED
arrays are also much more energy ef?cient that traditional
light sources, and offer the option of multiple colors and rapid
on/off cycles.
The present invention includes lighting and audio
components in the same ?xture to create a lighting and com
munications panel. The panel assembly includes a square or
rectangular enclosure having a siZe and shape often corre
sponding to various suspended ceiling tiles or modular light
ing. The edges of the enclosure are con?gured to ?t into
standard ceiling grids, or to be ?ush mounted into a neW or
existing Wall or ceiling structure. There is a lighting element
generally parallel With the front edge of the tray, and Which
covers substantially the entire opening of the tray. The light
ing element can consist of traditional lighting sources such as
incandescent, ?uorescent, neon, or HID.
[0009] Alternatively the lighting element used in the
assembly may consist of an LED array, of generally tWo
types. A top ?ring LED array has many LED’s positioned in
grid patterns on a generally ?at panel. This plurality of LED’ s
can be programmed to light individually in a desired
sequence, in order to form letters, numbers, or various shapes
including arroWs, chevrons, logos, or symbols. The shapes
and symbols can be programmed to scroll along a linear path,
or to simulate motion in any direction.
[0010] A second variation is a side ?ring LED array, in
Which LED’s are arranged around the edge of a translucent
panel, to light the panel from only the edges. In either con
?guration, the LED’s are capable of changing color, so the
desired shapes can also be programmed in many color com
binations. The side ?ring LED array also lends itself Well to a

Without the use of the ?at horn to direct the sound Waves.
[0013] While the speaker system can certainly be used for
the more traditional background music, White noise orpaging
functions, the combination With the versatile LED lighting
array creates some very unique opportunities. For example,
the lights can be individually and independently programmed
to respond in pre-determined Ways to certain audio signals.
For example, in the case of a ?re signal sent to the audio
system, the lighting system can display red arroWs or chev
rons indicating the best path to an exit. The LED array could
also display scrolling text to indicate the emergency or haZ
ard, including several languages or pictorial displays.
Weather, chemical, or other haZard situations could be
handled in a similar fashion. A code blue emergency in a
hospital setting could be programmed to indicate blue chev
rons to guide responders to the appropriate location While the
audio system announces the information.
[0014] An additional opportunity Would be for the lights to
respond automatically to a particular audio frequency. For
example, the LED’s can be programmed to display chevrons
or text in response to a knoWn ?re alarm or siren frequency.
This programmed response could be passive, meaning that it

edge of the trim ring 50 and is similar in siZe and shape to the
horn enclosure ?ange 28 shoWn in FIG. I. The trim ring ?ange
52 of the trim ring 50 is attached adjacent to the horn enclo

of spring clips 54 or similar attachment devices as shoWn in

least one audio aperture 60 for alloWing the audio Waves to

could be a plurality of speakers 34 arranged in multiple
speaker housing ?anges 40 and With additional horn guides

combination of audio ranges such as Woofer, midrange and

loudspeakers.
clips 54 are sometimes attached to this trim stiffener 62 to
[0044]
retain the trim ring 50 to the horn enclosure ?ange 28.
[0038] As shoWn in FIG. 1, a light enclosure 70 is disposed
tively of another version of the lighting and audio communi
cation system 1011. The light enclosure 70a of the lighting and
adjacent to and above the trim ring 50, and generally centered
audio communication system 1011 consists of a frame 50a
surrounding a lens 58a Which can be clear or translucent glass
or plastic. The speakers 34a consist of at least one contact
transducer 10011 which attaches directly to the lens 58a of the
light enclosure 70a to produce audio sound Waves 88a.
[0045] The light source 82a in this application consists of a
side ?ring LED array 8411 Where the LED’s are disposed
around one or more edges of the lens 58a of the light enclo
inside the horn enclosure 20. The light enclosure 70 includes
a light enclosure back 74, light enclosure sides 76, and a light
enclosure front 78, Which together de?ne a light cavity 79.
There is sometimes a light enclosure ?ange 80 adjacent to the
light enclosure front 78, and normally extends outWard
around the perimeter of the light enclosure front 78. The light
enclosure ?ange 80 or light enclosure sides 76 are attached to
the horn enclosure sides 26 of the horn enclosure 20 by a
series of tabs 72 or other means of fastening together.
[0039] The space created betWeen the light enclosure back
74 and light enclosure side 76 of the light enclosure 70, and
the horn enclosure back 22 and horn enclosure side 26 of the
horn enclosure 20 de?nes a horn expansion area 86. The
purpose of the horn expansion area 86 is to guide sound Waves
88 emanating from the speaker 34 towards the audio aperture
60 of the trim ring 50 and into the ambient area adjacent the
horn enclosure opening 3 0. In order to further guide the sound
Waves 88, a bifurcation bar 90 may be attached to either the
light enclosure back 74 or the horn enclosure 20 to split the
sound Waves 88 into tWo or more directions of ?oW.
[0040] Inside the light cavity 78 is a light source 82 Which
is electrically poWered With either a 120V AC house current
or a loW voltage poWer supply, and attached to the light
enclosure back 74. One embodiment of the light source 82 is
an LED array 84, Which consists of a plurality of bulbs in a
plurality of roWs. Other light sources 82 include ?uorescent
or incandescent lights. There may be a plurality of tabs 72 at
various heights along the horn enclosure sides 26 to alloW a
number of different distances betWeen the light enclosure 70
and the lens 58 to provide a variation of diffusion levels of the
light source 82.
[0041]
The light sources 82 or LED array 84 may be con
trolled by a lighting circuit board 44, Which can also be
located remotely to control a series of lights. The lighting
circuit board 44 can control many aspects of the LED array 84
including brightness, color, patterns, text, scrolling, graphic
movement, and poWer management.
[0042] FIG. 3 and FIG. 8 are top vieWs of the lighting and
audio communication system 10, and illustrates that in order
to further enhance the ?oW of the sound Waves 88 toWard the

changing the color or intensity of the lights, forming shapes
such as chevrons, graphics or pictorials, text, or scrolling text
in several languages. It can also control the audio components
to send verbal messages, sounds or other signals as pro
grammed. It can also be con?gured to prompt an automatic
