[ 0059 ] fig4 shows yet a further embodiment of the present invention . a photo - therapy device 17 takes the form of a wall panel 18 . the wall panel 18 has dimensions of 3 feet by 6 feet by 3 inches ; however , the size of the wall panel 18 may vary depending on the size of the subject or object being treated . the wall panel 18 has 24 led &# 39 ; s 19 in each column along its smaller dimension of 3 feet and 48 led &# 39 ; s in each row along its larger dimension of 6 feet . there are a total of 1 , 152 led &# 39 ; s in the wall panel 18 ; 230 led &# 39 ; s emitting red light at 630 nm , 230 led &# 39 ; s emitting ir light at 880 nm , 231 led &# 39 ; s emitting blue light at 470 nm , 231 led &# 39 ; s emitting green light at 565 nm and 230 led &# 39 ; s emitting amber light at 590 nm . each led emitting in a particular color ( wavelength ) would alternate in a repeated pattern , for example , blue , green , amber , red , ir ( repeat , etc .). the led &# 39 ; s 19 in the wall panel 18 are connected to the control box 20 with its control knobs . the wall panel 18 if attached to a wall at an appropriate height and a person , animal or plant would be positioned in front of it for treatment . the subject of the photo - therapy treatment is positioned in front of the wall panel 18 for an appropriate amount of time at a distance from close proximity to several feet . for example , a wall panel 18 is hung on each side of a horse trailer ( inside ) and a horse placed between the wall panels 18 for treatment . another example , a bull rider or horseback rider who is in need of treatment stands between the wall panels 18 in the horse trailer or in a similar enclosure at a competitive event and is treated for relaxation , pain relief or healing . plants could also be placed in a room with a wall panel 18 on each side of the room and be treated by the light generating from the led &# 39 ; s of the wall panels in order to obtain faster and stronger plant growth . referring now to fig5 there is shown another embodiment of a photo - therapy device of the present invention which is used primarily for humans . the photo - therapy device takes the form of a full body bed 22 with a hollow enclosure 23 and a lid 24 and led &# 39 ; s embedded within the hollow enclosure 23 and lid 24 . the full body bed 22 has the following dimensions : 3 feet wide , 6 ½ feet long and a 20 inch depth ; obviously , these dimensions could vary . a control box ( not shown ) is built into the front side of the hollow enclosure 23 and control knobs 26 are connected to the control box . an electrical cord 27 will connect the control box to an electrical outlet or generator . there are a total of 2 , 304 led &# 39 ; s inside the full body bed 22 with 1 , 152 led &# 39 ; s on the inside of the lid 24 and 1 , 152 led &# 39 ; s on the inside floor of the hollow enclosure 23 . on the inside of the lid 24 , there are 230 led &# 39 ; s emitting red light at 630 nm , 230 led &# 39 ; s emitting ir light at 880 nm , 231 led &# 39 ; s emitting blue light at 479 nm , 565 led &# 39 ; s emitting green light at 565 nm and 230 led &# 39 ; s emitting amber light at 590 nm . the numbers of specific led &# 39 ; s emitting in a particular wavelength on the inside of the hollow enclosure 23 are the same as those on the inside of the lid 24 . each led for a given wavelength alternates in a repeated pattern , for example , blue , green , amber , red and ir . a person for treatment would lie down in the full body bed 22 , face up , with the lid 24 partially closed ; the photo - therapy treatment would provide a relaxation effect , pain reduction or healing of the person . this embodiment of the invention could also be used in a hospital or nursing home for the treatment of bedsores or it can be combined with piped - in music and thus produce a “ wave effect ” for deep relaxation or pain relief after an operation . it could also be used to stimulate the immune system of a human with a disease such as cancer , etc . fig5 shows the full body bed 22 with the lid 24 in the fully open position whereas fig5 a shows a patient 28 lying within the full body bed 22 for treatment with the lid 24 being partially closed . [ 0061 ] fig6 shows an application of the hand held model 7 of the present photo - therapy device being applied in close proximity to a small body area of a patient p being treated whereas fig6 b shows the photo - therapy device being applied to a larger body area of a patient p being treated , the latter application demonstrating a diffusion effect of the device . [ 0062 ] fig7 and 7 a are circuit diagrams showing how the led &# 39 ; s of the various embodiments of this invention are connected to a control box with control knobs for controlling or regulating the operation of the led arrays in the various embodiments . the circuit diagrams show the general scheme of a photo - therapy device of this invention that is designed to provide a luminous pattern for a specific therapeutic application . the geometric pattern and color ( s ) of the led array , the frequency and duty cycle of the led array and the total time of operation of the photo - therapy device can be varied to satisfy the requirements of an intended therapeutic application . for example , fig7 shows a circuit diagram for a photo - therapy device of the present invention which operates three different light source types ( led 1 , led 2 and led 3 ) each of which is energized independently by a processor 29 ( or microprocessor ) via a switch network 30 . the series strings of a particular light source type ( led 1 , led 2 and led 3 ) are divided into two groups , a and b , as shown in the circuit diagram . each group a and b of series light strings will normally be switched on and off in an alternate fashion to minimize the maximum power requirements of the system . each series of light strings a and b is energized by a constant current source 31 that insures proper operation of the photo - therapy device under varying conditions of temperature and supply voltage . in some therapeutic applications , the value of the constant current can be modified under the control of the processor 29 to conform to a custom pattern . the processor operation is controlled by the operator of the photo - therapy device by the setting of the control switch positions for time , frequency , pattern and custom . the time control switch will set the desired period of operation , the frequency control switch will set the alternating on / off rate between the a and b groups of light strings , the pattern control switch will directly select which light source type ( s ) ( led 1 , led 2 or led 3 ) to be energized or will select the custom mode of operation , and the custom control switch will select which pattern from the pattern memory module 32 that the processor 29 is to perform in this mode , the processor 29 can vary the time , frequency , power level and light source strings in any prearranged ( programmed ) sequence . for example , the processor 29 can be preprogrammed to provide the following patterns of illumination : a ) each color set on individually , b ) all color sets on simultaneously , c ) at least two color sets on simultaneously and d ) at least two color sets on for preset periods of time . the processor 29 may also be programmed to sequentially pulse the led sets of the photo - therapy device to emit light of different colors . the control circuit may also be adjusted for pulsed operation of at least two sets of led &# 39 ; s with pulse durations of in the range of from about 0 . 001 sec . to about 0 . 2 sec . and pulse repetition rates in the range of from about 4 hz to about 10 , 000 hz . the pulse duration may be approximately half the period of each cycle . the processor 29 can also provide indications of low battery level and an elapsed time of operation in the form of a lamp and , if enabled , an audible beep . for an indication of the elapsed time of operation , the treatment timer may be connected to a visual or audio means for indicating the remaining treatment time . although the means for indicating low battery level and elapsed time of operation are not shown , the addition of such means to the circuitry and equipment of the present invention would be obvious to one skilled in the art and is , therefore , not detailed here . the operation of each of the photo - therapy devices disclosed herein is started by depressing the start / stop push button 33 shown schematically in fig7 and a second depression of the pushbutton 33 will stop the operation independently of the time setting . typical applications of the photo - therapy devices described above do not preclude the use of keyboards for operator input , alternate displays for status information or the use of an external computer for control of the operation of the devices . the block diagram of fig7 shows the use of light emitting diodes ( led &# 39 ; s ) which operate over the application - specific spectrum . however , the general scheme is not limited to led &# 39 ; s but other light sources may be used such as incandescent lamps . the light sources are shown in a series connection to improve electrical efficiency . light sources of the same or different colors may be grouped as required for a particular application ,. light sources for the photo - therapy devices of this invention may include both the visible and invisible portions of the frequency spectrum . although fig7 shows that all the light sources in a given group are enabled at the same time , individual control of series strings is not precluded . the block diagram shown in fig7 a shows the light sources being driven by constant current sources on the low voltage side of the power supply . however , control from the high voltage side of the power supply is not precluded . a typical constant current source operating on the low voltage side of the power supply is shown in the block diagram of fig7 a and consists of an operational amplifier u 1 , an fet transistor q 1 and a resistor r 1 . u 1 will cause q 1 to conduct enough current ir to satisfy the relationship vs = vr = ir × r 1 or iled = ir = vs / r 1 . thus , the current through the led &# 39 ; s , i . e ., iled , is a function of vs and r 1 and independent of the varying characteristics of the led &# 39 ; s as a function of temperature , power levels and individual parts . the value of vs is determined by the switch position ( sw 1 a , sw 1 b , etc .) and is either the output of the digital - to - analog converter d / a or 0 volts . since both the switch and the converter d / a are under control of the processor 29 , the individual light source strings can be turned on and off at various power levels as required by the program . the power supply for the block diagram circuit of fig7 is normally a direct current ( dc ) voltage source converted from the normal house supply or a battery . alternative well known power sources can also be used . the power to drive the photo - therapy devices of this invention ranges from 10 w / cm2 to 30 w / cm2 . modifications of this invention will be readily apparent to those skilled in the art and it is intended that the invention be not limited by the embodiments disclosed herein but that the scope of the invention be defined by the appended claims .
