`color in the visible spectrum. The present invention takes
`advantage of these effects by combining the projected light
`from at least two light emitting diodes (LEDS) of difierent
`primary colors. It should be understood that for purposes of
`this invention the term ·'primary colors" encompasses any
`different colors that can be combined to create other colors.
`Computer lighting networks that use LEOs are also
`known. U.S. Pat. No. 5,420,482, issued to Phares, describes
`one such network that uses different colored LEOs to
`generate a selectable color, primarily for use in a display
`apparatus. U.S. Pat. No. 4,845,481, issued to Havel, is
`directed to a multicolored display device. II a vel uses a pulse
`width modulated signal to provide current to respective
`LEOs at a particular du ty cycle. U.S. Pat. No. 5,184,114,
`issued to Brown, shows an LED display system. U.S. Pat.
`No. 5,134,387, issued to Smith et al., is directed to an LED
`matrix display.
`Illumination systems exist in which a network of indi(cid:173)
`vidual lights is controlled by a central driver, which may be
`a computer-controlled driver. Such illumination systems
`include theatrical lighting systems. The USITf DMX-512
`protocol was developed to deliver a stream of data from a
`theatrical console to a series of thea trical lights.
`The DMX-512 protocol was originally designed to stan(cid:173)
`dardize the control of light dimmers by lighting consoles.
`The DMX-512 protocol is a multiplexed digital lighting
`control protocol with a s ignal to contro l 512 devices, such
`device including dimmers, scrollers, non-dim relays, param(cid:173)
`eters of a moving light, or a grapbicallig bt in a computerized
`virtual reality set. DMX-512 is used for control for a
`network of devices. The DMX-512 protocol employs djgital
`signal codes. When a transmitting device, such as a lighting
`console, sends digital codes, a receiving device, such as a
`dimmer, transforms these codes into a function command,
`sucb as dimming to a specified level. Witb digital systems,
`signal integrity is compromised less over long cable ru ns,
`relative to analog control. When a coded string of 0/1 digits
`are sent and received, the device will perform the desired
`40 task.
`In hardwa re terms, DMX-512 prorocol information is
`transferred between devices over metal wires using tbc
`RS-485 hardware protocol. This involves the use of two
`wires, known as a twisted pair. The first wire is referred to
`45 as a data+wire, and the second wire is referred to as a
`data- wire. The voltage used on the line is typically positive
`five volts. By way of example, to transmit a logical one, the
`data+wire is taken to positive five volts, and the data-wire
`to zero volts. To transmit a logical zero, the data+wire goes
`50 to zero volts, and the data- wire to positive five volts. This
`is quite different from the more common RS-232 interface,
`where ooe wire is always kept at zero volts. In RS-232, a
`logical ooe is transmitted by pulling between positive six
`and positive twelve volts on the line, and a logical zero is
`55 transmitted by putting a voltage between negative six and
`negat1ve twelve volts onto the line. RS-485 is generally
`understood to be better ror data transmission than RS-232.
`With RS-232, the receiver bas to measure if the incoming
`voltage is positive or negative. With RS-485, the receiver
`60 only needs to determine which line bas the higher voltage on
`it.
`The two wires over which RS-485 is transmitted are
`preferably twisted. Twisting means that disturbaoces on tbe
`line tend to affect both lines simult<tneously, more or less by
`65 the same amount, so that the voltage on both lines will
`fluctuate, but the diJierence in voltage between the lines
`remains the same. The result is tbat noise is rejected from the

`DESCRIPTIO N OF TilE RELATED ART
`
`Light emitting diodes arc known which, whe n disposed
`on a circuit, accept electrical impulses from the circuit and
`convert the impulses into light signals. LEOs are energy
`efficient, they give off virtually no beat, and they have a long
`lifetime.
`A number of types of LED exist, including air gap LEOs,
`GaA<; light-emitting diodes (which may be doubled and
`packaged as single unit offer greater reliability than conven(cid:173)
`tional single-diode package), polymer LEDs, and semi(cid:173)
`conductor LEDs, among others. Most LEDs in current use
`are red. Conventional uses for LEDs include displays for
`low light environments, such as the !lashing light on a
`modem or other computer component, or the digital display
`of a wrist watch. Improved LEOs have recently been used in
`arrays for longer lasting traffic lights. LEOs have been used
`in scoreboards and other displays. Also, LEOs have been
`placed in arrays and used as television displays. Although
`most LEDs in use are red, yellow or wbite, LEDs may take
`any color; moreover, a single LED may be designed to
`change colors to any color in the color spectrum in response
`to changing electrical signals.
`It is well known tha t combining the projected light of one
`color with the projected light of another color will result in
`the creation of a third color. II is also well known tha t three
`commonly used primary colors-red, blue and green--can
`be combined in different proportions to generate almost any
`

`line. Also, the drive capability of RS-485 drivers is higher
`than RS-232 drivers. As a result, the RS-485 protocol can
`connect devices over distances hundreds of times flm ber
`than would be possible when using RS-232. RS-485 also
`increases the maximum data rate, i.e., the maximum amount 5
`of data which can be transmitted over the line every second.
`Communication between devices using RS-232 is normally
`about nine thousand six hundred baud (bits per second).
`Faster communication is possible, but the distances over
`which data can be transmitted are reduced significantly if 10
`communication is faster. By comparison, DMX-512 (using
`RS-485) permits data to be sent at two hundred fifty thou(cid:173)
`sand baud (two hundred fifty thousand bits per second) over
`distances of hundreds of meters without problems. Every
`byte transmitted bas one start bit, which is used to warn the 15
`receiver that the next character is starting, eight data bits
`(this conveys up to two hundred fifty six different levels) and
`two s top bits, which are used to tell the receiver that this is
`the end of the character. This means that every byte is
`transmitted as eleven bits, so that the length of each char- 20
`acter is forty-four micro seconds.
`The receiver looks at the two incoming signals on a pair
`of pins and compares tbe differences. A voltage rise on one
`wire and the inverse on the other will be seen as a differential
`and therefore deciphered as a digit. When both signals are 25
`identical, no difference is recognized and no digit deci(cid:173)
`phered. If interference was accidentl y transmitted along the
`line, it would impart no response as long as the interference
`was identical on both lines. The proximity of the two lines
`assist in assuring that dist
