According to another embodiment of the present invention, the SCM may condition the power to supply the drive signal to the LEEM in a form that can indicate the drive current, drive voltage, or both current and voltage for driving the LEE. it can. According to another embodiment of the present invention, the SCM can provide a drive signal to the LEEM that simply indicates the drive current or drive voltage required to drive the LEE. Depending on the configuration of the drive signal, the LEEM can convert the drive signal to the drive current or drive voltage required to drive the LEE, if necessary. If necessary, the LEEM is operatively connected to the PSM to receive power to operate the LEE directly from the PSM rather than through the SCM.

  According to some embodiments of the present invention, the SCM is configured to operate over a wide range of input voltages or input currents supplied by the PSM. For example, the SCM may be operatively connected to an optimally configured controllable PSM such that the SCM controls the output of the PSM.

Drive signal The drive signal is analog or digital. The driving signal supplies information for generating one or more driving voltages or one or more driving currents, or the driving signal supplies one or more driving voltages or driving currents by itself. Digital drive signals are pulse signals such as pulse width modulation (PWM), pulse code modulation (PCM), bit angle modulation (BAM) or other random digital drive signals (as will be readily understood by those skilled in the art).

The RDS can be set to a real-time precalculated duty cycle that is within a predetermined time based on data received from the processing unit.

Current limit circuit (CLC)
According to one embodiment of the present invention, the SCM includes a drive circuit that generates a LEE drive current that includes a current limit circuit (CLC) to suppress unwanted drive current spikes during drive current transients.

Can be configured to ensure that it is inside. CLC is used in certain embodiments of the present invention to avoid damaging the LEE or otherwise damaging other parts of the solid state lighting system caused by excessive drive current. According to another embodiment of the invention, the CLC is used to ensure accurate feedforward control of the intensity of light emitted by the LEE under operating conditions. Feedforward control in combination with a current limiting function is used to facilitate LEE luminance feedforward control of high-frequency pulse width modulation controlled solid state lighting systems.

Autocalibration In one embodiment of the invention, the SCM can evaluate the appropriate forward voltage for LEE during an autocalibration procedure and then set it to a previously calibrated value. The calibration procedure maintains the desired color and intensity of the light emitted by the LEE in each of the predetermined number of LEE color channels, while the predetermined number of each channel for each LEE color channel. Determine the lowest forward voltage required to provide the desired drive current. As is known, when the drive current is lower than a predetermined minimum nominal drive current, the chromaticity of the light emitted by some types of LEE deviates undesirably from its nominal value. This affects the configuration and performance of an appropriate automatic calibration procedure.

  The calibration procedure takes into account information regarding the LEE operating temperature to avoid overheating. As is already known, the forward voltage needs to decrease with increasing LEE operating temperature in order to maintain the same drive current. The LEE operating temperature can be obtained, for example, from a LEE forward voltage or a temperature sensor. The LEE voltage is detected by a circuit that can supply a number of sensors and appropriate sensor signals to the SCM. A programmable closed loop circuit can be used to determine, set and maintain the forward voltage to be supplied to the LEE.

  In one embodiment of the invention, the SCM can access a memory associated with the LEEM having information related to the light emitting element associated with the LEEM. In this way, the SCM can actively access information that can provide a means for calibration.

  The SCM is further configured to control the input power and at least partially control the LEE optical output level based on a predetermined correlation between the LEE optical output level and the input power. The SCM is further configured to control power loss, heat generation, and both in the SCM and LEE modules. The SCM is configured with a predetermined response time to control the described features without causing an undesirable delay or latency of at least some useful light output. Thus, undesirable heating effects are reduced and overall system efficiency can be improved. Repeated readjustment after an appropriate operating time can effectively maintain the desired brightness and chromaticity of the light emitted by the LEE, which provides good system performance and long system lifetime. For example, even a small efficiency improvement can significantly reduce system power requirements. According to one embodiment of the present invention, for example, an auto-adaptive SCM that can reduce system power requirements by 10% can reduce the operating temperature of the SCM module by 10 ° C. An exemplary embodiment of SCM is illustrated in FIG.

  Different embodiments of the SCM are adapted to control different numbers of LEE channels. The LEE module can be designed to have LEEs that are placed or classified in the LEE channel by a nominal color, if desired. For example, a LEE channel is a series connection or other connection of two or more LEEs. LEE channels also have more complex combinations of LEE and other devices.

The CPU processes the input data and converts it into an optimally formatted stream of instructions for controlling the VCC 530 and CHSC 540 in a compatible manner.

  A multi-master architecture can be implemented using a multi-master protocol for communication between two microprocessors via a serial I2C bus system. The speed of communication along the I2C bus system is programmable. The CPU processes instructions, for example, according to an adaptive control method to determine each minimum forward voltage required on each LEE channel to obtain the desired LEE drive current. The CPU is configured to receive a current detection signal from the CSC 520 and send a command to the VCC 530 to provide an appropriate forward voltage.

VCC 530 receives the address and instructions from CPU 510, processes the instructions, and provides respective output voltage levels for each LEE group defined by the received address. VCC includes volatile or non-volatile memory in which addresses and instructions are stored.

  The PSVC 555 can supply this information to the PSM using a digital-to-analog conversion system for receiving data in digital format from the CPU 510. For example, the PSVC 555 is configured to convert the information into an analog signal for application to an error amplifier of a power supply voltage regulator. The SCM is configured to regulate the output voltage of a PSM (not shown) operatively connected through PSVC 555. The PSVC 555 can supply power to the VCC 530 via the CSC 520.

The SCM is configured such that each analog signal is converted so as to fit in a predetermined range, and further subjected to analog-digital conversion for processing. As shown, analog to digital conversion occurs in CPU 510 or alternatively in a separate device (not shown). The CSC 520 can optionally provide information regarding the LEE group voltage.

  The CHSC 540 can use digital circuitry to enable or disable the LEE group channel according to the received CPU instructions. The CHSC has one or more channel selection circuits (EN GRx) per LEE group (GRx). The CHSC can be accessed by any CPU microprocessor 512 or 514.
