DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a hybrid lamp and a method for driving a hybrid lamp. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hybrid lamp assembly including a fluorescent lamp and a light emitting diode (LED) and a method for driving the fluorescent lamp and the LED. [Prior Art] A hybrid lamp contains at least two types of lamps. For example, the hybrid lamp can include a fluorescent light k and at least one light emitting diode (LED). This type of hybrid lamp is suitable for color control of the light output by the hybrid lamp. In particular, LEDs can be used in many colors, so they are suitable for use in changing - the fluorescent lamps that are transmitted by fluorescent lamps are well known. A well-known hybrid lamp includes a -first driver circuit for supplying a current to the fluorescent lamp and a second driver circuit for supplying a flow or voltage to the coffee. Because of the %, the two driver circuit is provided to operate the hybrid lamp. Such hybrid lamp driver circuit configurations are complex and relatively expensive. In addition, a 'difficulty' is required for a complex user interface to achieve the desired level of light and the desired color of light. Same as #, the user interface is more complicated and relatively expensive. SUMMARY OF THE INVENTION One object of the invention is to provide a hybrid lamp having a single driver circuit that can be reduced in brightness and/or light color controllable. In a first aspect, the present invention provides a hybrid lamp assembly including a fluorescent lamp, a driver circuit for supplying a high frequency alternating current to the fluorescent lamp, and at least a (four) circuit for connecting the lamp in series . Each coffee circuit comprises at least three parallel branches: one of the first branches of an impedance circuit, each package 1] 6608.doc 200808120 contains at least one LED, one second branch and one 筮 - two second brothers road. At least one LED of the second branch and at least one g of the second branch are connected in reverse parallel from the earth ^ LED system. In the above hybrid lamp unit, the fluorescent lamp driver is used to supply the high frequency alternating current to the fluorescent lamp. For example, the lamp driver circuit can include a half bridge inverter circuit. A separate phase circuit component can be provided to control the (pre)heating of the fluorescent lamp. The at least-LED system is contained within an LED circuit that is connected in series to the fluorescent lamp and is thus connected to receive the same high frequency AC power as the material light. The LED circuit includes at least three parallel circuit branches. A first circuit branch includes an impedance circuit. The second and third branches comprise at least one LED. Since the -LED allows current to flow only in the - direction, the at least one LED in the second branch is connected in anti-parallel with the at least one LED in the third branch, thereby allowing the alternating current to flow at any time Pass the second branch or the third branch. The impedance circuit controls the amount of current flowing through the second and third branches (i.e., flowing through the at least - LED). If the impedance of the residual reactance circuit is high, a larger portion of the current flows through the second or third branch; if the impedance is lower, a smaller portion of the current flows through the second or third portion Branch road. Since the alternating current may flow through the LED circuit at any time, the LED circuit can be connected in series to the fluorescent lamp without interfering with the operation of the fluorescent lamp. This current can be a steady state drive current 'but can also be a (pre)heat current or any other high frequency alternating current. Thus, there is no need to adapt the fluorescent lamp driver circuit. Moreover, the fluorescent lamp driver circuit can also be used as an LED driver circuit. A circuit that is connected in series to an impedance circuit, 116608.doc -7-200808120, is known in the art. For example, US 2003/0043611 A1 discloses a high frequency inverter circuit connected to an anti-parallel connection LED. The LEDs connected in anti-parallel are connected in series to an impedance circuit. The impedance of the impedance circuit is controlled by frequency control on the inverter circuit. The impedance of the impedance circuit affects the amount of current drawn to the LED such as δHai. Thus, the brightness of the LEDs can be controlled. In a specific embodiment, the method includes changing a frequency of the high frequency alternating current to control a light output of the fluorescent lamp. Thus, the light output of the fluorescent lamp and the LED circuit is controllable. It should be noted that it is known in the art to control the frequency of the alternating current in order to illuminate the fluorescent lamp. Moreover, in a specific embodiment, the method includes changing one of the high frequency alternating current duty cycles to control the light output of the LED circuit and the fluorescent lamp. The duty cycle of the alternating current indicates which cycle of the alternating current is not equal to zero. Thus, the circulatory cycle indicates which portion of the cycle the glory lamp and/or the LED system actually supplies to the motor. Therefore, if the duty cycle is large, the LED circuit and the glare light have a large light output. If the duty cycle is small, the light output is low. a As noted above, it is known in the art to vary the frequency of the alternating current to illuminate the glory. Add at least one LED to add color control to the functionality of the worklight. In order to obtain a desired LED light output, the frequency dependent impedance will be configured in accordance with the frequency used to operate and reduce the glory. It will be understood by those skilled in the art how to design and construct features having such desired impedance characteristics - in particular embodiments, the impedance circuit includes a resistor having a - variable resistance. The resistance of the resistor directly affects the impedance of the impedance circuit. 116608.doc 200808120 Similarly, an impedance circuit can include a capacitor having a variable capacitance and/or a variable inductance and/or an inductor for affecting impedance characteristics of the impedance circuit. Thus, the impedance of the impedance circuit and thus the light output of the LEDs can be controlled independently of the frequency of the alternating current. It should be noted that the above-described manner of controlling impedance (frequency dependence, variable resistance, variable capacitance, variable inductance) may be combined in a specific embodiment. Thus, one or more control parameters can be used for brightness and/or color control. In addition, in addition to a resistor, a capacitor, and an inductor, other active components can be used to provide a suitable impedance circuit. In a particular embodiment, the hybrid lamp assembly includes a control circuit and a sensor coupled to the control circuit. The control circuit is configured to control the impedance of the impedance circuit in response to a signal received from the sensor. The sensor may be a light sensor that determines at least one parameter of a set of parameters 'these parameters include the amount of light output by the hybrid lamp, the color of the light that the mixing wheel emits' flows through the LEDs or flows through The amount of current in the impedance circuit. The sensor can also determine any other parameters suitable for controlling the light output by the hybrid lamp. In a particular embodiment, the control circuit can be coupled to the driver circuit ' to control the frequency of the high frequency alternating current. Thus, the control circuit can control the LEDs to control the frequency of the LEDs 无 ^ ^ 无 无 无 , , , , , , , 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无 无The impedance of the circuit and possibly by controlling the frequency to control the light out of the fluorescent lamp. In addition, the present invention relates to all the way: - the first branch ... into, the lighting circuit of the branch circuit eight packs two impedance circuit, and a second branch and a 116608.doc 200808120 brother two branches each contain at least "(four), At least the LEDs of the second branch are connected in parallel with at least the LEDs of the third branch. In a particular embodiment, two or more circuits of such lighting circuits are connected in series. The light output of each illumination circuit can be controlled by controlling the impedance of each impedance circuit. It should be noted that the illumination circuit system is provided herein as being provided in a hybrid lamp assembly that includes a fluorescent lamp. However, the lighting circuit can also be used with any other current control circuit. If the current is - direct current, one of the led branches can be omitted because the current flows only in one direction. In another aspect, the invention provides a method for driving a hybrid light assembly. The hybrid lamp assembly Xiao Jinyi signature, the peak ^3 burner, the driver circuit for supplying a high frequency alternating current to the fluorescent lamp and the LED circuit including at least three parallel branches. A first branch includes an impedance circuit, and the second circuit and a third circuit each comprise at least an LED. At least one of the second branches of the second branch is connected in anti-parallel with at least one of the LEDs of the second branch. The LED circuit is connected in series to the camper light. The method includes: supplying a high frequency alternating current to the camping light and the LED circuit; and changing an impedance of the impedance circuit to control a light output of the LED circuit. In a particular embodiment, the step of varying the impedance comprises varying the frequency of the high frequency diaphragm muscle. In another embodiment, the impedance circuit includes a resistor having a variable resistor, and the step of changing the impedance includes changing the resistance of the resistor. Similarly, the impedance circuit can include a capacitor having a k-capacitance and/or a variable inductance, and/or an inductor, and the step of changing the impedance can include changing the inductance of the inductor or the capacitor. capacitance. As described above, the frequency of change can be combined in a particular embodiment, 16608.doc - 0-200808120 to change the resistance, change the capacitance, and/or change the characteristics of the inductance. In one embodiment, the hybrid lamp assembly includes a control circuit and a sensor coupled to the control circuit, the method further comprising providing a desired light output setting to the control circuit; Determining a light output parameter of the hybrid lamp assembly; supplying the control (four) way with a parameter signal including one of the light output parameters from the sensing; and responding to the parameter signal to control the impedance of the impedance circuit. [Embodiment] Fig. 1A shows a prior art lamp driver circuit for operating a fluorescent lamp. The lamp driver circuit includes two input terminals 11, 12 for receiving a -Dc voltage. The high frequency inverter circuit including the switching elements S1, S2, the inductor [丨 and the capacitors a, C3 converts the direct current voltage into an alternating current between the circuit nodes N1, N2i. The capacitor C1 is for adjusting a heating current for heating one of the electrodes of the fluorescent lamp FL and for lighting the glory. It should be noted that the inverter circuit is essentially used as a current source. Figure 1B shows an LED lighting circuit LEDC with a terminal Ding Ding 2. This electric

The first: branch light (two) LEDijleDi is connected in reverse parallel to the LED of the third branch LED 2 ^ to LED In operation, during the period of the alternating current, the current flows from the first terminal T to the second terminal by 2. The third branch of the fourth branch (four) 116608.doc 200808120 (LEDn to LED^) blocks this current. However, the impedance circuit and the LEDs of the second branch (LED" to LEDln) allow this current to flow. Therefore, depending on the impedance of each branch, the current The two will be shunted on the two branches. During the second period of the alternating current, the current flows from the second terminal 2 to the first terminal T1. The LEDs of the second branch (LED" to LEDin) Blocking this current. However, the impedance circuit VRC and the LEDs (LED21 to LED2n) of the third branch allow this current to flow. Therefore, depending on the resistance of each branch, the current will be in the two Diverting itself on the road. The impedance of the 3rd and 2nd branches is constant. The impedance circuit Vrc The impedance can be changed. Therefore, the flow of the current can be affected by changing the impedance of the impedance circuit VRC. For example, during the first period of the alternating current, the impedance of the impedance circuit is higher, and one of the currents is larger. Part of the LEDs (LEDi^LEDin) flowing through the second branch, thereby generating light output of the LEDs (LEDU to LED) n). If the resistance of the impedance circuit is lower, one of the children is less Most will flow through the impedance circuit and only a small portion of the current will flow through the LEDs (LED" to LEDin) of the second branch, thereby producing one of the LEDs (LEDijLED) n) Low light output. Figure 1C", the member is used in one of the impedance circuits VRC in the BiLED circuit of Figure 1. This embodiment includes a resistor having a resistance σσ VR that can be manually controlled or electrically controlled by a suitable control circuit. Figure 1D shows another embodiment of an impedance circuit VRC. The impedance is 116608.doc -12- 200808120 The road VRC contains the -LC circuit. - The inductor L2 is connected in parallel with a capacitor. The impedance circuit has an impedance that depends on the frequency of the alternating current supplied to the circuit vrc. Thus, by varying the frequency of the alternating current, the impedance of the impedance circuit can be varied. The inductance of the inductor [2] and/or the capacitance of capacitor C4 is variable and can be controlled manually or electrically. Thus, the impedance characteristics of the impedance circuit can be controlled. Referring again to Figure 1B, any alternating current or direct current supplied to the LED circuit LEDC may flow through the LED circuit LEDC at any time. Thus, the LED circuit ledc can be incorporated into another circuit that supplies a current through a current source without affecting any other circuit operation. Figure 1E shows a hybrid lamp assembly that includes a fluorescent lamp FL and a corresponding driver circuit as shown in Figure VIII, and includes a circuit LEDC as shown in Figure ib. Since the LED circuit LEDC does not affect the operation of the fluorescent lamp fl and its corresponding driving circuit, therefore, the fluorescent lamp? The operation of ^^ can be the same as described with respect to Fig. 18. The light output of the light assembly of Figure 1E can be controlled by frequency control. As described above, the fluorescent lamp FL can be lightened by changing the frequency of the alternating current. For example, the fluorescent lamp FL can be operated with '卟^^ which produces a higher light output. As is well known in the art, increasing the frequency of the alternating current to 65 kHz can perform the light output of the dimming fluorescent lamp FL. The frequency control for refracting the fluorescent lamp can be advantageously used to control the light output of the led circuit ledc connected in series with the fluorescent lamp FL. In particular, changing the light output of the fluorescent lamp FL and/or the light output of the LED circuit LEDC can be used for color control, because the color of the light output by the fluorescent lamp and the color of the light output by the LEDs Not H6608.doc 13 200808120 Q. Therefore, the combination of the fluorescent lamp and the coffee beans depends on the amount of light of the amount of light output by the fluorescent light. In the case, the output of the β Temple LED is, for example, 'in one of the above works. One (4) sheep 4 kHz, the -t light FL output is set first, and the light system is perceived as white light. At Hz, the impedance circuit (e.g., one of the impedance thunder & impedance circuits shown in Figure 1D) has a feature that causes the current to pass through the impedance circuit, which makes it extremely difficult to produce any light output. Thus, the light output of the hybrid lamp assembly is substantially equal to the light output of the fluorescent lamp FL. As the frequency is increased, the impedance of the impedance circuit is summed such that at the resonant frequency (e.g., 65 kHz), the light output of the fluorescent lamp fl is at a minimum (i.e., substantially zero). Thus, the LEDs of the LED circuit ledc output a maximum amount of light while the fluorescent lamp fl does not output any until the resonance frequency of the impedance circuit is reached. This impedance =, light can be designed. Therefore, the color of the light output by the hybrid lamp assembly is substantially equal to the color of the light output by the LEDs. Since the LED can be used in many colors, the resulting color can be almost any color, for example, red or green. Of course, depending on the impedance of the impedance circuit, the color of the light will gradually change in response to a varying frequency. Instead of controlling only the frequency of the alternating current, the impedance of the impedance circuit can be directly controlled, e.g., using one of the variable resistors shown in Fig. 1C. An advantage of this specific embodiment is that the light of the glory L is individually controlled to output light with the LED circuit LEDC. Thus, the frequency can be varied to control the light output of the fluorescent lamp FL, and the impedance of the impedance circuit can be varied to control the light output of the LED circuit LEDC. Of course, in one embodiment, 116608.doc -14-200808120 controls only the impedance of the impedance circuit. In another implementation, the light output of the LED circuit LEDC and the light output of the xenon lamp FL are controlled by a duty cycle. The alternating current duty cycle can be controlled by the driver circuit (especially the switches S1, S2), thereby controlling the amount of current supplied to the LED circuit LEDC and the fluorescent lamp FL. ^ The amount of current supplied determines the light output. Figure 2 illustrates another embodiment of a hybrid lamp assembly in accordance with the present invention. The hybrid lamp assembly includes a fluorescent lamp FL and an lED circuit LEDc. – The high frequency alternating current is supplied by a driver circuit : (:: the driver circuit is connected to a control circuit CC 〇 a sensor § is connected to the control circuit CC. The control circuit cc can control three controls The parameters cTRL1, cTRL2, CTRL3 are in operation, the sensor S determines an operating parameter of the hybrid lamp assembly. The sensor S can be an optical sensor that determines a light output and/or the light output One of the colors. The sensor s can also be a thermal sensor for determining the generated heat 1, that is, heat radiation from one of the hybrid lamps. The sensor S can also be any other suitable sensing. The sensor S can determine an operating parameter 'but can also determine two or more operating parameters. A parameter signal is supplied from the sensor s to the control circuit CC. The control circuit cc is supplied The parameter signal is configured to generate a light output corresponding to a user setting. Based on the user setting and the value of the (equal) operating parameter supplied by the sensor S, the control circuit cc determines to use the And other control parameters CTRL1, CTRL2, CTRL 3i an appropriate value of one or more control parameters 116608.doc -15- 200808120 The first control parameter CTRL 1 may be the frequency of the high frequency alternating current. The second control parameter CTRL2 may be the working cycle of the high frequency alternating current. The three control parameters CTRL3 may be the impedance of the impedance circuit of the LED circuit LEDC. The control parameters CTRL1, CTRL2 and CTRL3 are not necessarily independent. For example, the first control parameter CTRL1 (ie the frequency of the alternating current) may affect the impedance of the impedance circuit. (ie CTRL3). In a specific embodiment, the control circuit CC may not have all three control parameters CTRL1, CTRL2, CTRL3 as actual control parameters. For example, the control circuit CC may be configured to control only the frequency of the alternating current In a specific embodiment, the sensor S can be omitted. For example, the control circuit CC can then have a memory that stores a lookup table containing a number of control parameters corresponding to an individual number of user settings. Figure 3 illustrates another embodiment having four LED circuits LEDC1, LEDC2, LEDC3 and LEDs connected in series with a fluorescent lamp FL C4. A driver circuit DC may supply an appropriate south frequency parent galvanic power in response to any control parameter or signal CTRL. Since any current may flow through the LED circuits LEDC1, LEDC2, LEDC3, LEDC4 without interfering with the current, it may be connected in series Any number of LED circuits. The impedance characteristics of each LED circuit determine the light output of each separate LED circuit. The hybrid lamp assembly and method for driving the hybrid lamp assembly can be used as a backlight for a liquid crystal display (LCD), such as an LCD television In particular, it acts as a backlight to increase the color gamut of the LCD-TV. Moreover, additional drivers for driving the LEDs can be omitted, comparing prior art hybrid lamp assemblies, thereby providing a cost reduction. 116608.doc -16- 200808120 The detailed embodiments of the present invention have been disclosed, but it should be understood that the present invention is not limited by the specific embodiments.
