be provided from your Wired or Wireless transmitter/receiver
and may include digital signal processing of the signal.
BACKGROUND OF THE INVENTION
[0002] Most houses are constructed today include one or
more can style lighting fixtures Were the lighting fixture is
recessed into a Wall or ceiling. Many house is also include
an intercom or speakers that are also mounted in the Wall or
ceiling. The installation of the lighting and sound are usually
provided by different tradesman during the construction of
the house. Some patents have been issued on products to try
to combine the lighting and sound as a single element.
[0003] U.S. Pat. No. 1,272,843 issued to H. G. Pape on
Jul. 6, 1918, U.S. Pat. No. 4,433,363 issued on Feb. 21, 1984
and U.S. Pat. No. 4,528,620 issued on Jul. 9, 1985 both

digital signal processing to account for placement or fixture
construction. The orientation of the sound producing ele
ments is also not adjustable to direct sound Waves to a
particular location.
[0004] U.S. Pat. No. 4,776,018 issued to Cordier on Oct.
4, 1988 and U.S. Pat. No. 5,980,057 issued to Cristie on
Nov. 9, 1999 both disclose screW-in combination lighting/
sound fixtures. Both of these tWo patents are for a standalone
screW in lighting fixture that can be installed inside an
existing lights socket and include a Wireless receiver for
receiving audio signal. Neither of these tWo patents provide
a recessed lighting fixture they’re simply lighting elements

DETAILED DESCRIPTION
[0025] FIG. 1 shows an isometric view of the combination
light and sound fixture 10 before installation into a ceiling or
wall. In this preferred embodiment the fixture 10 is in a
cylindrical can configuration 20 where the can has an
opening at one end for emission of the light and sound, and
a closed end where the fixture exists in a wall or ceiling. But
it is also contemplated that the end can be opened. In this
preferred embodiment the fixture is fabricated from metal,
plastic or other structural material as would be found in
recessed or wall mounted fixtures. Tabs 24 or other securing
holder that allows the orientation of each tweeter to be
adjusted. In this preferred embodiment four tweeters are
used, but the fixture could be made using just one tweeter or
more that four. It is further contemplated that a single wide
range speaker can be used in the fixture. In another contem
plated embodiment a third mid range speaker is utiliZed to
provide improved sound. The outside facing surface of the
woofer and some or all of the tweeter(s) may be coated with
a highly refiective surface to refiect light.
[0027] The refiective surface of the sound emitting com
ponents refiects light from lighting elements 60. In the
preferred embodiment multiple LED lighting elements are
placed in a ring within the fixture. LED lighting is used
because it is easily configured to provide even lighting, LED
lights operate at a lower voltage, LED lights are more
efficient than most other forms of lighting, and LED’s
produce light with minimal heat. A total of 9 LED’s oper
ating at 1 watt of power will produce the same brightness as
a 60 watt incandescent light bulb. The operation life expect
ancy of LED’s is 100,000 hours resulting in 10 to 20 times
longer life than a standard incandescent light bulb. The
LED’s may have a heat sink in physical proximity or in
contact with the lighting element(s) to provide cooling ofthe
lighting element(s). While the preferred illumination ele
ment is LED’s, other forms of illumination include but are
not limited to incandescent, fiuorescent, neon and halogen.
The low operational voltage of LED lights allows power to
be supplied to the fixture at a voltage that might not require
the installer to be a licensed electrician thereby allowing the
fixture to be installed by the same person that installs the

fixture 50 and 52. The mid/high frequency sound transducers
are moved outside ofthe fixture to enhance the quality ofthe
placed in a junction box 62 located within the fixture
(shown) or external to the fixture. Power to the lighting
elements 60 is brought 64 from the electrical junction box 62
to the LED’s.
[0028] The power converter reduces the incoming voltage
(120 VAC) into a lower voltage of about 3.1 volts to operate
the LED’s. The operating voltage can include the audio
signal superimposed on the power lines, or can be brought
into the fixture from a separate electrical connection and
then into a separate audio junction box 70. The audio
junction box can include a Digital Signal Processor (DSP) to
adjust the sound from the speakers to produce anything from
a fiat frequency response to a fixed directional response that
can include surround sound. The user can further use the
DSP to switch between omni-directional usage to facilitate
distributed audio and also THX home theater applications.
The DSP further can filter out 60 cycle noise to reduce or
eliminate the 60 cycle noise from being transmitted out of
the speakers. The DSP filter may include a notch or digital
filter for canceling out extraneous noise such as power lines
but can also filter out other signals that could couple into the
audio signal. A screen 32 is shown covering the exposed
surface of the fixture 10. The covering is constructed to
allow the passage of both light and sound from the fixture.
[0029]
ln another contemplated embodiment the tweeters
and or woofer and or light can extend from within the fixture
to below the fixture as shown and described in FIG. 3 to
improve the sound. ln a number of installations it is not
desirable for the sound to be heard in other rooms and to
combat this issue sound insulation can optionally be placed
around the outside of the fixture to reduce sound from being
sound that may be muted or experience diffraction or dis
persion problems when they operate within the fixture. A
drive mechanism 55 moves the transducers inside and
outside of the fixture using threads 90 or other movement
mechanism(s). ln the preferred embodiment the transducers
are moved with a mechanical drive mechanism, but sole
noids or other mechanical devices are contemplated. ln the
embodiment shown the transducers are linearly translated,
but altemative movement systems are contemplated where
the transducers are hinged or pivot to move them in and out
of the fixture. A flexible covering 34 covers the outfacing
surface of the fixture and when the transducers are lowered,
the flexible covering stretches to accommodate the trans
ducers. The flexible covering is removable to allow access to
the interior of the fixture for replacement or servicing of the
transducers, drive mechanism and or the lighting elements
60.
[0032] The fixture is shown in a circular can 20 configu
ration but may also exist as a squared, rectangular, geometric
or irregular shape. The fixture is shown recessed in a wall or
ceiling with drywall 35 or sheet rock holding the fixture in
location or as a barrier within the wall. Tabs 24 retain the
fixture in position on the wall or ceiling sandwiching the
drywall with facia ring 30 located on the visible side of the
fixture. The low frequency transducer 40 is supported 44 in
the fixture and the position or depth of this transducer may
be fixed or manually repositioned. All the transducers are
typical construction for speakers including either a coil 42,
heard in other rooms where the sound is not desired.

of lighting elements 60 is shown inside the fixture. This ring
of lighting elements is replaceable to allow for upgrading or
[0030]
changing lighting elements in the future. The outside facing
FIG. 2 shows an isometric view of a surface
mounted combination light and sound fixture 10. ln this
contemplated embodiment the fixture is configured as a
surface mount fixture to give the appearance of a retro style
lighting fixture. The enclosure 25 is shown here in a squared
or rectangular configuration, but other shapes are contem
plated that provide the same or similar appearance to light
ing fixtures that may be present in older homes or configured
to be used in newer homes. ln this figure separate covering
32 exist over each of the speakers. The LED lighting 60
exists around the central woofer 40. While this figure shows
separate coverings over each speaker it is contemplated that
surface ofthe woofer and some or all of the tweeter is coated
with a highly reflective surface to reflect light outside the
fixture.
[0033] The LED’s are powered by lower voltage, high
voltage can be brought into the fixture and the voltage
reduced with a power converter placed in a junction box 62
located within the fixture (shown) or external to the fixture.
Power to the lighting elements 60 is brought through elec
trical conduit connection 80 to the electrical junction box 62
to the LED’s.

volts for the LED’s it is contemplated that any voltage can
exist on the comers of the fixture and are oriented in
different directions to provide a more even distribution of
higher frequency sounds. The tweeters can be positioned in
fixed orientations or can be attached to individual gimbals
where they can be individually oriented. As an example, if
the fixture is located near a wall, two of the tweeters can be
