Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a quick start circuit for a solid state lighting system. More specifically, the various inventive devices and methods disclosed herein relate to lower piezoelectric circuits for use with dimming circuits in solid state lighting systems. [Prior Art] Digital or solid-state lighting technology (ie, illumination based on semiconductor light sources, such as light-emitting diodes (LED) and food-emitting diodes (〇LED)) provides for traditional fluorescent lamps, high-intensity discharge (HID) A viable alternative to lamps and incandescent lamps. The functional advantages and benefits of LEDs include high energy conversion and optical efficiency, durability, lower operating costs, and others. Recent advances in LED technology have provided efficient and robust full-spectrum illumination sources that enable a variety of lighting effects in a multi-application. Some of the luminaire features including such sources are a lighting module that includes one or more LEDs that are capable of producing white light and/or different color lights 'eg, red, green, and blue; and a controller Or a processor for independently controlling the output of the LEDs to produce various color and color-changing illumination effects, for example, as disclosed in U.S. Patent Nos. 6, , 16, 038, 6, 211, 626, which are incorporated herein by reference. No. 7 and 〇 14, 336, are discussed in detail. Many lighting applications use dimmers. Although conventional dimmers work well with incandescent lamps, this special dimmer and other types of electronic lamps (including compact fluorescent lamps (CFL) 'low voltage halogen lamps (using electronic transformers) and solid state lighting (SSL) Lamps (such as LEDs and OLEDs) _ often cause problems when used. Special 150453.doc 201208241 It is possible to dim the low voltage ssl unit using an electronic transformer using a specific dimmer such as, for example, an electric low voltage (elv) type dimmer or a valley block (RC) 5 period lighter. . = The illuminator usually contains an electronic switch. When the switch is closed (turned on), a voltage is applied to the output, and when the switch is turned off (turned off), no voltage is applied to the output. Different types of electronic switches can be used in conventional dimmers, e.g., can be used to maintain a minimum current, a three-terminal bidirectional alternating M. switch, which is the holding current of the stomach. Low wattage lights (such as LED lights) typically do not take this minimum current at low dimming levels, causing the three-terminal bidirectional AC switch to not switch, causing the light to flash. Other dimming benefits use metal oxide semiconductor field effect transistors (5) 〇sfet) or insulating gate bipolar transistors (IGBT) as the electron (5) off. These switches do not have a minimum electrical pick-up requirement and, therefore, LED lights are typically better matched to such dimmers based on non-three-terminal bidirectional AC switches. Conventional dimmers typically intercept the waveforms of the various waveforms (sine waves) of the mains voltage signal and pass the remainder of the waveform to the lighting fixture. A leading edge or forward-phase dimmer intercepts the leading edge of the voltage signal waveform. A trailing edge or reverse-phase dimmer intercepts the trailing edge of the voltage signal waveform. Electronic loads (such as LED drivers ||) are generally better operated with trailing edge dimmers. Unlike incandescent lamps and other resistive lighting devices that respond naturally to a parabolic waveform produced by a dimmer, LEDs and other ssl units or lamps have the time from when a user turns on the light to when the light is actually turned on. A significant delay in time. This delay may be too long from the time the physical power on the SSL unit or luminaire is turned on, 150052.doc 201208241, to the time the light is first seen by the luminaire. The reason for this delay is that the power converter has sufficient starting voltage and begins to convert power from the unrectified line I to the time it takes to power the SSL unit or luminaire according to the dimming ϋ setting. This time delay depends on various f-numbers, such as available rectified (Urect) (for example, as determined by the truncated waveform of the main supply voltage signal based on dimming), from the node Urect to the node The impedance of Uce (which supplies power to the power converter integrated circuit (1C)) and the capacitance from node vcc to ground. So-called "instantaneous start" circuits have been developed to address this delay. However, combining the instantaneous (four) circuit (4) reading (four) optical setting (4) results in a significant delay from the time the flip switch is turned on to turn on the SSL unit or luminaire until the time the light is seen. For example, the instantaneous starting circuit can be passive, for example consisting of a single circuit. In general, the lower the impedance of the starting network, the faster the power converter will be turned on. However, in the case of a passive Rc start-up network, the power loss increases with the turn-on time, which results in lower power efficiency and therefore lower overall lamp performance (e.g., lumens per watt). Thus, there is a need in the art for an instant start circuit that provides sufficient power to the power converter buckle of a solid state lighting unit or luminaire within a span of the dimming level, and particularly at a lower dimming level. SUMMARY OF THE INVENTION The present invention is directed to an inventive method and apparatus for providing a fast start possibility for power conversion of a solid state lighting unit and a luminaire at a low dimmer setting. In general, in one aspect, a means for quickly starting a power converter during a start-up period is provided, the power converter controlling the power of a solid state lighting load. The device comprises: a low impedance path Γβ1 temporarily formed between the rectified voltage node and the power converter voltage to form a power converter charge 用于β1 for further splicing the 罝 远 == converter and an auxiliary winding A diode between the two poles has a small bypass capacitor - a capacitor connected to the ground « one of the cathodes and connected to the anode with a large capacity t _ to the ground voltage. Charging the first capacitor and not charging the second capacitor when forming a diameter during the starting period

The description of well-known devices and methods may be omitted so as not to obscure the description of the representative embodiments. Apparently within the scope of this teaching. Affirmatives have recognized and understood that providing a reduction in start-solid state, especially in low dimmer settings The lighting unit or the luminaire - the switch to the time between 150453.doc 12 201208241 - the circuit will be defective. In other words, please understand that you need to provide a solid-state lighting single s and low dimmer settings One of the luminaires is a quick start possibility for a power converter. Figure 1 is a quick start circuit for powering a solid state lighting system (e.g., using one or more LED light sources) according to a representative embodiment. A block diagram of the quick start circuit 12A includes a first (depleted) transistor 127, a second transistor 28, representative resistors 121 to 125, and a pole 129 (shown separately). For the purposes of the following explanation, the first transistor 127 is a field effect transistor (FET) and the second transistor system is a bipolar junction transistor (BJT), but can be implemented without departing from the scope of the present teachings. Other types of transistors. The quick start circuit 12 〇 provides a voltage Vcc to the power converter 13 (or power converter 1 (:) such that the power converter 130 can start up faster during the start of the operation and start transmitting power of the autonomous power source to the SSL load in the future. 140. The start-up period is used to fully charge the auxiliary winding 丨6〇 and to cause the voltage να force converter 130 to be in steady state to the Vcc node N102. However, it takes time to reach a steady state value. In the middle, the auxiliary winding 160 provides a voltage, and when the power converter 130 is in the off state, the auxiliary winding 16A cannot be used to start the power converter 13A, so some other components, such as the quick start circuit 120, are provided. The auxiliary winding 160 typically acts as one of the additional windings of the main magnetic power used by the power converter 130 to convert power. Thus, the auxiliary winding 160 uses a small portion of the energy in the main winding to power the power converter 130. For example, the SSL load 14〇 It can be a solid state lighting unit or luminaire or other system. I50453.doc •13· 201208241 Quick start circuit 120 via dimming hot line (Dim Hot) and dimming neutral line (Dim Neutral) And receiving (dimmed) rectified voltage Urect from the dimmer (not shown) through the diode bridge or bridge rectifier 110. When a dimming setting has been selected, the rectified voltage Urect has a leading edge Or the trailing edge paraplegic waveform, the extent of the parabolic waveform depends on the selected dimming, where the low dimmer setting results in a more appreciable waveform paraplegia and thus a lower rectified voltage Urect rms. Once rectified voltage Urect node N101 can be coupled to ground voltage by capacitor C1 U (eg, about 〇丨 microfarad) to filter the switching current of power converter 1C. Obviously, those skilled in the art will appreciate that all of the descriptions are provided. The various values are illustrative and can be determined according to the particular situation of various embodiments or application specific design requirements, such as using US voltage, European voltage, or some other voltage. The rectified voltage Urect is connected by bridge rectifier 110 To a dimmer via a dimming hot line and a dimming neutral line (not shown). Initially, the dimmer is received from a power source via a mains power source ( Dimmed) is not rectified. Typically, the unregulated voltage has a voltage value (eg, between about 90 volts AC to about 277 volts AC) and corresponds to one of the substantially sinusoidal waveforms of the AC line voltage signal. The dimmer includes an adjuster that can automatically and variably select a dimming setting, for example, by a user manually variably selecting a dimming setting or by a processor or other setting selection system. In one embodiment, the adjuster achieves a setting in the range of about 20 〇/〇 to 90% of the maximum luminance of the SSL load 14 。. In various embodiments, the dimmer is also a phase parallax (or Phase cut) A dimmer that intercepts the leading or trailing edge of the input voltage waveform, thereby reducing the amount of power reaching the SSL load of 14453.doc -14 - 201208241. For purposes of explanation, it is assumed that the dimmer is a trailing edge dimmer that cuts a variable number of one of the trailing edges of the unrectified sinusoidal waveform. In general, the 'quick start circuit 120 temporarily generates a low impedance path from the Urect node N101 to the Vcc node N102 during startup'. This occurs when the auxiliary winding 1 60 has not been fully charged (for powering the power converter 130) and When the voltage Vcc has not reached a steady state value. For example, when the SSL load 140 is turned on (e.g., via a dimmer adjuster or other physical switch), the starting voltage of the auxiliary winding 160 is zero and will remain at zero until the power converter has the opportunity to start during startup. The power for the start of the power converter 130 is drawn by the fast start circuit i2's R 丨 2 1 (e.g., about 22 kilo ohms) and the depleted first transistor 127 to charge the capacitors C112 and C113. After the power converter 130 has been started, the auxiliary winding 16 turns through the diode 15 turns to supply the voltage Vcc to the power converter 13 and the first transistor 127 is made high by the activation of the second transistor 128, as follows Discussed. Capacitor C112 provides a small bypass capacitor (eg, about 0.1 microfarad) connected between Vcc node N1〇2 and ground to shunt high frequency noise, and capacitor Ci 13 provides connection between Vcc node N102 and ground. Large-capacity capacitors (eg, about 1 〇 microfarad) 'to provide lower frequency filtering and temporary retention. More specifically, at the beginning of the start-up period, one of the C0MP signals received at the base of the second transistor 128 is initially low. In the representative example depicted, the second transistor 128 also includes a collector connected to one of the resistors R123 (e.g., about 100 kilo ohms) and one of the emitters connected to the ground voltage. The low COMP signal turns off the second transistor 128 and thus effectively disconnects the second transistor 128. In the depicted embodiment, 150453.doc •15·201208241 is provided for the COMP signal via node m〇3, which is coupled to Vcc node N102 via resistor R124 (eg, approximately 100 kilo ohms). The voltage Vcc is connected to the ground voltage through a resistor 125 (eg, about 1 〇〇 kilo ohm). Since the rectified voltage Urect has not yet charged the auxiliary winding 16〇 and thus the voltage Vcc at the vcc node is not yet at a steady state value, the c〇MP signal is initially low due to the low voltage Vcc. Because the second transistor 128 is turned off, the gate of the depleted first transistor 127 is connected to the source of the depleted first transistor 127, for example, via a resistor r122 (eg, about ι Ω). . In this state, the impedance of the depleted first transistor is low. One of the first transistors 127 is connected to the Urect node N101 via a resistor R121 (e.g., about 22 kilo ohms). When the system is energized, the rectified power | Urect is high, and the electric disk ycc starts to be charged by the resistor thief R121 and the first transistor 127. When the voltage Vcc is charged to the desired voltage, the power converter 13 is activated to supply power to the SSL load 140, and the C OMP is south. The south COMP signal is turned on to connect the gate of the first transistor 127 to the second transistor 128 of the ground voltage through the resistor R123. In this state, the first transistor 丨 27 is turned off, and its impedance becomes high, which effectively turns off the rectified voltage Urect and the Vcc node N102 at the Urect node N101. In other words, when the COMP signal is low, the rectified voltage Urect at urect node N101 is connected to Vcc node N102 through a low impedance, and when the COMP signal is high, the low impedance is turned off. In addition, the quick start circuit 120 includes a diode 129 that separates the bulk battery C 113 from the small bypass capacitor C112, thereby reducing the total capacitance from the Vcc node N102 to ground during the startup transient. In one embodiment, two 150453.doc •16·201208241 pole body 129 includes one of the anodes connected to ground through an electric grid C113 and one cathode connected to ground via a capacitor C112. When the mechanical switch on the dimmer (not shown) is turned on, the voltage from the auxiliary winding 160 is at or close to the ground voltage, assuming that the SSL load 140 has been turned off for a sufficient amount of time and the diode is made 129 reverse bias. Since the COMP signal is initially low, the second transistor 128 is turned off, and the gate and source of the first transistor 127 are connected, so that current is allowed to pass from the rectified electric dust Urect node N201, through the resistor ri21, and first. The transistor 127 flows to the Vcc node N1 02, as discussed above, initially charging only the capacitor C112 without charging the capacitor CU3 that has been effectively removed from the circuit by the diode 129. Because of the capacitor, CU2 is a small value capacitor for bypassing the Vcc node N102, the fast start circuit 丨2〇 can quickly charge the capacitor C112 for the operating voltage of the power converter 13〇 even if the Urect node N101 The rectified voltage mountain 6 is very small, for example when the dimmer is at its lowest setting. The bulk capacitor 匚213 is not removed when Vcc is at a steady state voltage value, but only the voltage at the auxiliary winding 160 is low. The bulk capacitor C213 is removed during the start-up. That is, in the steady state, the diode 129 is turned on, thereby enabling the capacitor C113 to be connected to the voltage Vcc at the Vcc node, which provides the benefit of the reduced-capacitor capacitor. In addition, after the power converter 130 has started to operate, the c〇Mp signal becomes high and the second transistor i 2 m is turned on to cause the first transistor to turn off and thus the urect section = N101 The rectified electric ^Urect and Vcc node Nl〇2 are effectively turned off, as discussed above. 150453.doc 17 201208241 Therefore, the diode 129 of the quick start circuit 120 effectively cuts off the large gap of the capacitor C113 during the start transient.

In various embodiments, the dimmer can be a two- or three-wire electronic low-rise (ELV) dimmer, such as, for example, a LUtron Diva DVELV_3 dimmer available from Lutron Electronics, Inc. For example, the ssl load 140 can be a -LED or OLED lighting unit or a sun and moon system. The various components shown in Figure} can be configured to differ from the different pre-packaged configurations of the depicted packets. For example, bridge rectifier 110, fast start circuit 12A, power converter 130, and SSL load 140 can be packaged together in a single product, such as an EssentialWhiteTM lighting fixture from Philips Color Kinetics. Various embodiments may include any type of dimmer, illumination system, and/or package without departing from the scope of the present teachings. The dimmer provides a dimmed rectified voltage (e.g., having a truncated waveform) to the power converter 13 through the bridge rectifier 110 and the fast start circuit 12A. The power converters 130 can include the structures and functionality described in, for example, U.S. Patent No. 7,256,554, the entire disclosure of which is incorporated herein by reference. The power converter 13 can be constructed of any combination of a hardware architecture, a firmware architecture, or a software architecture without departing from the scope of the present teachings. For example, in various embodiments, power converter 130 can be implemented as: a controller, such as a microprocessor, ASIC, FPGA; and/or a microcontroller, such as 150453.doc 201208241 from one of ST Microelectronics L6562 PFC Controller. As explained above, when the dimmer is adjusted to a low setting, the rms voltage of one of the dimmer outputs is relatively low (eg, about 35 volts or less), and usually there is not enough energy transferred to assist The magnetic power of the windings is 6 〇 to supply power to the power converter 1 3 〇 ', thereby causing the shutdown. However, according to this embodiment, the low dimmer level is detected by the failure of the voltage Vcc of the voltage divider formed by the resistors R124 and R125, and the quick start circuit 120 is activated via the COMP signal. After the quick start circuit 120 is activated, the rectified main power supply is supplied to the power converter 13 through the resistor R121 and the depleted first transistor 127 (for example, implemented as a fet). When the first transistor 127 is turned on, the power is turned on. The converter 13 can even operate during low dimmer levels to prevent negative priming effects such as delays and light flicker. In other examples, the low dimmer level can be detected by an entity (such as a controller or microcontroller) not depicted in FIG. 1, and the C〇MP signal can be controlled by this body only. Start or not start the quick start circuit 12 as needed. It will be appreciated that while representative values have been provided above for purposes of discussion, those skilled in the art will appreciate that the values of capacitors C111 through CU3 and resistor scales 121 through R125 are specific to various embodiments or application specific design requirements in accordance with various embodiments. And judge. 2 is a block diagram showing a quick start circuit for powering a solid state lighting system in accordance with another representative embodiment. Referring to Figure 2, the fast start circuit 220 includes a transistor 225, a diode 226, representative resistors 211 through 212, and a second diode 227 (shown separately). For the purposes of the following explanation, the transistor 225 is a BJT and the first two-pole system is a Zener diode 150453.doc • 19-201208241 body, but other types of electricity can be implemented without departing from the scope of the present teachings. Crystal and / or diode. Referring to the quick start circuit 120 of FIG. 1, the fast start circuit 22 provides a voltage να to the power converter 230 (or power converter IC) for powering the ssl load 240 until it is given The auxiliary winding 26 is fully charged and the voltage Vcc has a - steady state value. The fast start circuit 220 receives the (dimmed) modulo/claw C Urect from the dimmer through the diode bridge or the bridge rectifier 21 via a dimming hot line or a dimming neutral line. § When a dimming setting has been selected, the rectified voltage Urect has a leading or trailing edge parabolic waveform. The width and height of the parabolic waveform depends on the selected dimming setting, and the low dimmer setting results in a more observable waveform paraplegia. And thus resulting in a lower rectified voltage Urect rms ^ a rectified voltage Urect node Ν 2 (Π can be coupled to the ground voltage by a capacitor C2U (eg, about 微 1 microfarad) to filter the switching current of the power converter. The light-heating line and the dimming neutral line provide a rectified voltage urect from a dimmer (not shown) through the bridge rectifier 210. Initially, the dimmer is received from a power source via the main power source of the power (not Dimming) is not rectified. Generally, 'the unregulated voltage has a voltage value (eg, between about 90 volts AC to about 277 volts AC) and corresponds to one of the generally sinusoidal waveforms of the AC line voltage signal. The dimmer includes an adjuster that can automatically and variably select a dimming setting, for example, by a user manually variably selecting a dimming setting or by a processor or other setting selection system In one embodiment, the adjuster achieves a setting in the range of about 20% to 90% of the maximum luminosity of, for example, an SSL load of 24 。. In various embodiments, the adjustment is 150453.doc -20-201208241 The optical device is also a phase parabolic (or phase cut) dimmer that intercepts the input or the trailing edge of the input waveform to thereby reduce the amount of power reaching the SSL load 240. The speed-start circuit 220 is very low. The dimming setting is particularly effective. According to the representative embodiment depicted, even if the rectified voltage Urect at the Urect node N201 is very low (e.g., at the lowest dimmer setting), the fast start circuit 220 is lowered during startup. The voltage at the vcc node n2〇2 from the voltage vcc to the ground voltage and the resistance from the rectified voltage Urect at the Urect node N2〇1 to the voltage Vcc at the Vcc node N202 during startup avoids visible delay. After 23 〇 has been activated, the auxiliary winding 260 provides a voltage Vcc to the power converter 230 through the second diode 227 and the third diode 250 discussed below. More specifically, the fast shown in FIG. start The circuit 22 includes a first diode 226 having a cathode connected to one of the nodes 〇2 〇 3 and an anode connected to a ground voltage. The fast start circuit 22 〇 also includes a transistor 225 having a connection to the node 203 A base is coupled to one of the nodes N2〇1 (one of the rectified voltages and one of the Vcc nodes N202 (voltage Vcc) through a resistor R2丨2 (eg, about 5 kohms). Node N203 is also coupled to Urect node N201 via resistor R2U (e.g., about 2 〇〇 kilo ohms). Resistor scale 211 is capable of flowing sufficient current through first diode 226 when voltage Vcc has been fully charged. The base of transistor 225 is held at a steady state voltage value that is slightly lower than Vcc at Vcc node N2〇2. However, when the voltage Vcc is below the voltage at the base of the transistor 225 (such as during startup), the transistor 225 is turned on, thereby providing self-rectifying power 150453.doc -21 - 201208241 pressure Urect, through the resistor R212 and transistor 225 to a low impedance path of voltage VCC' thus reduce the impedance from the rectified voltage Urect node N201 to the Vcc node N202 during the start transient (before charging the auxiliary winding 26). In addition, the 'quick start circuit 220 includes a second diode 227 that separates the capacitor C213 of the large capacity valley (for example, about 1 micro method) from the capacitor C212 of the small bypass capacitor (for example, about 1 micro method). This reduces the total capacitance from the Vcc node N202 to ground during the startup transient. In one embodiment, the second diode 227 includes one of the anodes connected to ground via capacitor C213 and one of the cathodes connected to ground via capacitor C212. When the mechanical switch on the dimmer (not shown) is turned on, the voltage from the auxiliary winding 260 is at or close to the ground voltage, assuming that the SSL load 240 has been turned off for a sufficient amount of time, and the second two The polar body 227 is reverse biased. Because the resistor R211 biases the first diode 226, the transistor 225 is turned "on" to allow the capacitor to flow from the rectified voltage Urect node N2〇i, through the resistor R2 12 and the transistor 225 to the Vcc node N202, As discussed above, capacitor C212 is initially charged only without charging capacitor C213 that has been effectively removed from the circuit by second diode 227. Because capacitor C2 1 2 is a small value capacitor for bypassing vcc node N202, fast start circuit 220 can quickly charge capacitor C212 for the operating voltage of power converter 230, even if rectified at Urect node N20 1 The voltage Urect is very small 'for example when the dimmer is at its lowest setting. The bulk capacitor C213 is not removed when Vcc is at a steady state voltage value, but is removed only during startup when the voltage at the auxiliary winding 260 is low. 150453.doc • 22- 201208241 Powered by the Chopper. That is, in steady state, the second diode 227 is turned on, thereby enabling the capacitor C213 to be connected to the voltage % at the Vcc node N2 〇 2, thereby providing chopping that reduces the benefits of a large-capacity capacitor. Additionally, after power converter 230 has begun operation, transistor 225 is turned off because first diode 226 is selected to have a breakdown voltage that is slightly below the steady state voltage Vcc. In this manner, the second diode 227 effectively cuts off the capacitor C213 of the bulk capacitor during the startup transient, but allows it to be connected during steady state operation. By turning off capacitor C213 during startup, voltage Vcc can be fully charged faster, even if the rectified voltage Urect is very low (such as when a dimmer is at its lowest setting). It should be understood that although certain representative values have been provided above for purposes of discussion, those skilled in the art will appreciate that the values of capacitors C2U through C213 and resistors R211 through R212 are specific to a particular situation or application specific design in accordance with various embodiments.

Just as 「t _ _L ♦ 叙^^, the term "or" (as used in this article) is added to exclusive terms (such as "any one", "one of" or "the one that is exactly one") Previously, it should only be interpreted as indicating an exclusive substitute (one or the other - but not both) "consisting essentially of .. ·" should be used in the field of patent law when used in the scope of patent application. It should be understood that the phrase "at least the evening" (as used herein) in the specification and the application of the list of one or more components means to be selected from the list. Any of the elements in the list of components - at least one of the components of the component, but not necessarily including at least one of the components listed in the component list and not excluding the components of the component list枉可..合合. This definition also allows for the presence of a condition other than a specific identification in the list of S-smuggling items in the phrase "at least - .^ ^ ^", regardless of whether or not Related to these components. Therefore, as a non-limiting example, "A and B "at least one of" (or equivalently "at least one of A or B - this, f"' or equivalently "at least one of A and / or B") H in the case of 'may mean at least - (as appropriate Including more than one) A and no presence includes elements other than )); in another example 150453.doc -25· 201208241, it may mean at least - (as the case may include - more than one There is A (and optionally includes elements other than New Zealand); in the case of _, it can mean at least - (including more than one) A and at least one (including more than one if necessary) B (and optionally Other elements); etc. It should also be understood that, in the absence of any explicit indication, the order of the steps or actions of the method is not necessarily limited to the method. The order in which the steps or actions are listed.
