    15 20 25 30 35 The device has also been used with great success for wound treatment, for example for diabetic foot ulcers, and in elderly care and further in aesthetics and equestrian sports.
    There is thus an insight that light treatment by emitting certain light in certain frequency series gives a significantly increased effect in the form of shortening the time for a disease to cure or alleviate a disease.
    Since the light treatment is assumed to have an effect already at the cellular level, it is desirable to use a dynamic light image and that the entire area of the body to be treated receives an equal amount of light over time. For example, those who are treating a problem with the mentioned devices, described in Swedish patent 502 784 above, in order to meet the requirement for a dynamic light image and as large an amount of light over time as possible, must perform an oscillating movement with the light emitting means when it abuts or is held close to the area of the body of the individual to be treated. The reason for this is that the LEDs which are arranged at the bottom of the light emitting member have a certain geometric extent, which is why there is a certain distance in order to be whole and of different kinds, between two nearby LEDs of the same type. the area to be treated must be exposed to as even lighting as possible, the light-emitting body must therefore be moved back and forth over the area.
    Since a treatment typically takes about two to ten minutes, it is very burdensome for the staff to perform such a treatment often.
    It is therefore previously known to arrange an eccentric device between the housing of the light emitting means and the plate which in this case carries the LEDs, see Swedish patent 515 992. the eccentric device comprises a first part which is fixed h: docworkkmsöksextdoc, Arranged relative to the housing and a second part which is connected to the LED plate and a spring which prevents rotation of the plate. An electric motor is arranged to drive the eccentric device, whereby the plate with the LEDs performs an oscillating movement.
    It is also previously known to arrange an electric motor fixed relative to the housing of the light emitting member and which is connected to the LED plate via a drive shaft, 515 991. a rotating movement, see the Swedish patent Hereby the plate with the LEDs will perform whereby it is obtained overall. a more even lighting and increased cellular response in the area to be treated.
    A disadvantage of the devices described above for achieving the required oscillating or rotating movement is that they are both based on a mechanically generated movement pattern where expensive and relatively heavy components are built into the device. This in turn leads to higher production costs, increased wear and thus increased costs for maintenance and the risk of complaints. Requests for as friction-free components as possible lead to tight tolerances during manufacture and strict requirements when assembling the moving parts.
    An additional disadvantage of the mechanically generated movement pattern is that the movement takes place in a plane and thus limits the geometry of the diode plate. There is a desire to increase the degree of freedom both with respect to the geometric shape of the diode plate as a movement pattern.
    There is therefore a need to provide a device with lower weight, lower production and maintenance costs and increased freedom with respect to the geometric design of the diode plate and generated movement pattern. The present invention solves this problem by replacing the mechanical rotation with an electronically generated movement pattern. An electronically generated movement pattern provides significantly greater freedom with respect to the desired movement along the body part to be treated and does not include any mechanically moving parts. It provides the opportunity for a more arbitrary movement along the body part to be treated and an opportunity to design the diode plate into a shape that is more adapted to the body part to be treated.
    The present invention thus relates to a device for medical treatment externally by means of light. The device comprises a light emitting means arranged to abut or be held close to the body of an individual and a drive device for the light emitting means, which light emitting means comprises LEDs or the like which LEDs are arranged to emit light in different path length intervals, where the drive device is arranged to control the light emitting means for emitting one or more lights during one or more predetermined times and arranged to pulsate emitting said light according to a predetermined pulse frequency or series of pulse frequencies during said times, said light emitting means comprising a housing and a plate carrying the LEDs and where the LEDs are arranged, for example, in matrix form on said plate so that there is a certain distance between two adjacent LEDs.
    According to the invention, an electric drive circuit is arranged for sequential or otherwise predetermined control of the LEDs, which drive circuit is connected to one or more of the individual LEDs and is arranged to switch on and off them so that a moving light image appears over the surface of the LED plate. According to an advantageous embodiment, the LEDs are arranged in matrix form in rows and columns on the plate.
    According to a further advantageous embodiment, the drive circuit comprises a separate drive circuit arranged to control one or more rows of LEDs in the matrix and a separate drive circuit for controlling one or more columns of LEDs in the matrix SGD. In the following, an exemplary embodiment of the invention will be described in more detail with reference to the accompanying drawings, in which - Figure 1 shows a light emitting member according to the invention in a side view, - Figure 2 shows diagrammatically a block diagram of a device according to the invention, - Figure 3 shows in principle how different movement patterns can be generated over the surface of the LED matrix by sequential control of the LEDs with row and column drivers, - Figure 4 shows two examples of movement patterns, where several movements are created simultaneously , partly non-overlapping movements and partly overlapping movements, - Figure 5 shows an embodiment where the surface-mounted LEDs are provided with optical lenses to give the desired light image, - Figure 6 shows two embodiments where the LEDs are arranged and arranged in clusters of the light emitting means.
    Figure 1 generally shows a device for medical external treatment by means of light comprising a light emitting means 1 arranged to abut or be held close to the body of an individual. The light emitting means is shown in the figure from the side and comprises a housing 2 provided with a transparent disc 3. Under this disc 3 inside the housing there is a surface 4 in which a number of LEDs 5,6 are mounted in matrix form, see figure 2. The LEDs 5,6 are arranged to emit light through the disc 3 when they are supplied with current via a cable 7. In use, the housing 2 is held so that the disc abuts against or close to the relevant body part of, for example, a person whose wound injury is to be treated.
    Furthermore, the device comprises a drive device for the light emitting means, see the block diagram in Figure 2, where the light emitting means 1 is also shown from below. The drive device is arranged to control the light emitting means 1 to emit different monochromatic lights of different wavelengths for different predetermined times and to emit said light pulsating according to a predetermined pulse frequency or series of pulse frequencies during said times.
    The light emitting means 1 may comprise a type of LEDs 5 which are arranged to emit, for example, infrared light.
    These are marked with filled circles in the figure. Visible light can be emitted by means of other LEDs 6, which are marked with unfilled circles in the figure. The LEDs 5,6 for infrared light and visible light, respectively, are preferably semi- (Gallium arsenide). GaAs type LEDs The LEDs can also be arranged to emit light with other wavelengths. Thus, the light emitting means 1 may comprise LEDs 5, 6 arranged to emit a substantially monochromatic visible light in any of the colors violet, blue, yellow, orange, red or green as well as infrared and other invisible wavelengths.
    Which of these to use depends on the disease or type of injury to be treated. The LEDs can be arranged in matrix form, in rows and columns, on the light emitting means 1.
    The drive device comprises a computer 8 for controlling drive circuits 9,110, which drive circuits are supplied with signals from the computer to in turn drive the LEDs via conductor 7. The computer and these drive circuits may be of a suitably known type and are therefore not described in more detail here. Connected to the drive device or the computer is a keyboard 13 by means of which the operator can key in data in order thereby to control the drive device to control the light emitting means 1 in the desired manner. Suitably there is also a display 14 for displaying the settings made by means of the keyboard 13. This display can be the computer display.
    The light emitting means 1 comprises LEDs 5, 6 arranged to emit a substantially monochromatic visible light h: docworkkmsöksextdoc, 2010-12-03 100234EN 10 15 20 25 30 35 in any of the colors violet, blue, yellow, orange red or green as well as infrared and other invisible wavelengths. Which of these candles to use depends on the disease or type of injury to be treated.
    The parts of the invention which have been touched upon so far are not described in more detail here, but reference is made to the above-mentioned Swedish patents.
    According to the invention, the device comprises an electric drive circuit arranged for sequential or arbitrary control, for example stochastic control or control according to some predetermined pattern, of the LEDs, which drive circuit is connected to the individual LEDs and arranged to switch on and off the LEDs, for example in sequence. moving light image appears over the surface of the LED matrix. Figure 2 schematically shows this drive circuit connected to the rows and columns of the diode matrix. According to an advantageous embodiment, the drive circuit comprises a separate drive circuit 11 arranged to control one or more rows of LEDs in the matrix and a separate drive circuit 12 for controlling one or more columns of LEDs 12 are connected to the computer there in the matrix. Drives ll, 8 and suitable power supply (not shown). The computer processor can, by default, control the drive circuits for rows and columns in the diode array so that a suitable moving light image appears across the surface of the diode array. By turning the individual LEDs on and off in sequence, the light intensity travels across the surface. A light pulse / light image appears and an arbitrary movement, for example a circular movement can be generated. This movement replaces the previously mechanically generated movement of the light emitting means.
    How different movement patterns can be generated across the surface of the LED matrix by sequentially controlling the LEDs with row and column drivers are shown in principle in Figure 3. The figure shows a matrix diagram with an imaginary LED in each cross and a switch for columns (A) and a switch for rows (B). h: docworkkmsöksextdoc, 2010-12-03 100234EN 10 15 20 25 30 35 An arbitrary LED can be lit by closing a switch (A) and a switch (B). By replacing the switches with transistors or drive circuits according to the invention, the current can also be varied and thus the brightness of an arbitrary LED. By ramping the light from the LEDs, i.e. increase the light intensity of a diode while reducing the light intensity of a nearby diode, one or more traveling light pulses (C) of suitable shape can be generated. By ramping the light from the LEDs, a desired dynamic light image can be achieved and a more even light intensity distribution over the matrix surface. Ramping can be done analogously or with s.k. pulse width modulation (PWM).
    By switching individual LEDs on and off, an arbitrary movement can be achieved, for example a circular movement indicated in Figure 3. The light pulse C “travels” along the circular path D as indicated in the figure. Multiple movements can be created simultaneously, see Figure 4, and overlapping movements can also be generated if desired, see Figure 4. The type of movement patterns to be used depends on the type of damage to be treated and controlled with appropriate software in the computer 8. It will be appreciated that the electronically generated motion allows a freer choice of motion pattern compared to mechanically generated motion.
    Figure 5 shows an exemplary embodiment where the surface-mounted LEDs 5, 6 are provided with optical lenses 15 to give the desired light image, preferably a reduced light scattering for the individual LEDs compared to the scattering angle they have in themselves and which is indicated by 16 in figure 5. In the example shown in the figure, it is assumed that small lenses l5 are mounted separately above each LED. Alternatively, a plate with several lenses in the same body can be mounted over the LEDs.
    As an alternative to the array of rows and columns of LEDs, the LEDs may be arranged in clusters on the plate 4 as shown in some examples in Figure 6. In this cluster 17, 2010-12-03 100234EN 10 15 20 25 cluster 17 , 18 which are controlled individually so that the clusters provide, for example, a rotating light image. In this case, the LEDs form round 'oar'. The invention is not limited to the embodiments given above but can be varied within the scope of the appended claims. The invention is thus not limited to the forms of treatment mentioned above but can be applied in all areas of external medical treatment by means of light, especially in wound care, equestrian sports and aesthetics. The invention is also not limited to any special layout or any specific movement pattern for the surface-mounted LEDs. h: docworkhnskningstexndoc, 2010-12-03 100234EN
