Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of LED lamps, and more particularly to the field of manufacturing LED lamps. [Prior Art] It is known that there is currently a trend from domestic and international regulations to incandescent lamps to more efficient light sources. One of the more efficient light sources is a compact fluorescent lamp, often abbreviated as CFL. The CFL is a type of fluorescent lamp suitable for fitting to one of the many existing luminaires used in incandescent lamps. The CFL can be divided into: a non-integrated CFL in which the gas filled tube of the lamp is releasably assembled in the lamp housing or on the lamp housing and can be replaced independently of its corresponding driver; and the integrated CFL (generally designated as CFLi) ), wherein the gas filling tube is permanently installed in the lamp housing or on the lamp housing. In the event of a failure of the CFLi gas filled tube, the entire product needs to be replaced. The acronym CFL therefore refers to two types of lamps and does not distinguish between integrated and non-integrated CFLs unless specifically stated. The CFL is now available in a wide range of applications, and with the ban on incandescent lamps, market size is available. However, with the advent of LED lights, more and more CFLs have been replaced by more efficient LED lights. As a result, the CFL will be replaced with an LED lamp in the near future, but the CFL is still expected to function properly. A large number of CFLs will then be recycled from the market to the waste collector. However, from an environmental point of view, it is important to recycle CFL for recycling rather than disposal as waste material 159022.doc 201228461. The goal of the present invention would be to treat the recycling of a properly functioning CFL in an environmentally friendly manner. SUMMARY OF THE INVENTION To address one or more of these concerns, a method for fabricating an LED lamp is provided that includes the steps of: a. providing a lamp housing; b. providing at least one LED; c. A CFL extracts a CFL driver; d_assembles the at least one LED, the CFL driver, and the lamp housing, thereby electrically connecting the at least one LED to the CFL driver. One advantage of the method according to the invention is that after the recovery of Cfl, the CFL driver is extracted and reused (i.e., reused) as a driver for the LED lamp. In this way, not only is the material of the CFL driver recirculated' and the functionality of the assembly is also recycled. As a result, the environment is less affected by the recycling of the CFL, and the manufacturing cost of the Led lamp can be reduced. In one embodiment, the lamp housing has electrical contacts to electrically connect the led lamp to a mains power supply. The lamp housing can be provided as a separate component 'so that step d) can include electrically connecting the CFL driver to the electrical contact of the xenon lamp housing or "or a portion of the lamp housing or the entire lamp can also be extracted from the CFL shell. In this case, the electrical connection between the CFL driver and the lamp housing may remain intact and the corresponding assembly steps of connecting the CFL driver to the electrical contacts of the lamp housing may not be required. An embodiment in which a portion of the lamp envelope is extracted from the CFL is also foreseen (the portion 159022.doc 201228461 is referred to as a CFL lamp housing), wherein the CFL lamp housing includes a formerly configured to connect the CFL to the utility power source. Electrical contact point. The remainder of the lamp envelope is then separately provided and referred to as an LED lamp housing, wherein the LED lamp housing has electrical contacts to connect the LED lamp to the mains power source. Step d) then preferably includes interconnecting at least some of the electrical contacts of the CFL lamp housing with the electrical contacts of the LED lamp housing to enable power to the CFL driver. The electrical contacts are automatically interconnected when the CFL lamp housing is mounted within the LED lamp housing or the LED lamp housing. For example, the above situation can be achieved by adapting an LED light fitting such that a smaller CFL light fitting can be inserted into the LED light fitting (eg, by threaded connection, which is common for light fittings) and can be automated The electrical connection between the LED lamp fitting and the CFL lamp fitting is performed. Since the CFL driver does not have to be separated from the CFL lamp housing (i.e., the accessory) and the CFL lamp housing can be easily mounted into the LED lamp housing, the method can be performed at a higher speed. It is also foreseen that the LED light is connected to the mains supply in a different manner (i.e., without a lamp housing, for example, using a wireless power source or an electrical contact that is not disposed on the lamp housing). In one embodiment, the CFL driver is extracted from an integrated CFL (i.e., CFLi). CFLi is particularly suitable for extracting both the CFL and at least a portion of the lamp envelope. The advantage of extracting at least a portion of the lamp envelope from the CFL is that, for example, due to existing electrical and/or mechanical connections between the extracted lamp housing and the CFL driver, more components are recirculated, and Less assembly steps may be required. 159022.doc 201228461 In an embodiment, the method includes the steps of providing a circuit configured to adjust an output of one of the CFL drivers to a drive signal suitable for the at least one LED, and wherein step d) includes The step of electrically connecting the at least one LED to the CFL driver via the circuit. Usually the '-CFL driver is configured to shake the bamboo, especially for the voltage and current of the fluorescent tube design, B < and the stomach b may even require certain properties of the tube (eg impedance) for proper operation . The desired operational characteristics of the at least one led may be different from the operational characteristics of the tube. By providing the circuit, the output signal of the 4 CFL can be adjusted to be suitable for the at least one [rib drive signal. The circuit can also be used to adjust the output signal of the CFL driver for other reasons, such as electrical isolation of the at least one led, reduced ripple current, dimming possibilities, and the like. In order to electrically isolate the CFL driver from the at least one (four) and/or adjust the voltage level, the circuit can be coupled to the CFX driver via a transformer. The transformer may also be part of the circuit and may even be based on components already present in the CFL driver but may already be used for different purposes in the CFL driver. The extracted CFL driver typically includes a CFL output that is originally intended to be connected to the CFL gas fill tube; and typically also includes a ballast inductor that is electrically coupled in series to the CFL output. The ballast inductor can be a discrete inductor component with two electrical connection pins, but can also be a more complex inductor component (such as an inductor with an electrical tap or a transformer with multiple '尧' The implementation of the expected inductive behavior or parasitic inductance behavior. 159022.doc 201228461 In an embodiment, a transformed state configured between the CFL driver and the circuit as described above can be coupled to the extracted. The wheel outlet of several drives In another embodiment, the original ballast inductor of the extracted CFL driver is removed and replaced by a transformer. In this case, the CFL output is preferably shorted to keep the circuit closed (if necessary). The original ballast inductor can also be used in the process of forming the transformer. For example, the ballast inductor acts as the primary winding of the transformer, and the secondary winding of the transformer is wound around the ballast inductor. Or, the transformer is electrically connected in series to the ballast inductor, and the CFL output is shorted (if necessary). The CFL output of the CFL driver can be provided with a parallel circuit that can be configured such that in the above-mentioned embodiments, the CFL output is not necessarily shorted. In one embodiment, the at least one LED and at least a portion of the circuit are mounted on an LED carrier. In an embodiment, step d) comprises the following sub-steps: dl) mounting the CFL driver into the lamp housing or the lamp housing; d2) electrically connecting the CFL driver to the electrical contact of the lamp housing; d3 Mounting the LED carrier to the lamp housing or to the lamp housing; d4) electrically connecting the circuit on the LED carrier to the CFUg actuator. Preferably, step d2) is performed automatically during step di). It is also preferred that step d4) is automatically performed during step d3). In an embodiment, step d) includes modifying the CFL driver. Modifications may include replacing components with different value but similar components, replacing components with groups of the same value 159022.doc 201228461 (eg, 卸^ dismounting due to deterioration due to aging, wear, etc.), adding components, Remove components and change the route of electrical wiring. The CFL driver extracted from /Hai may include a / degree dependent resistor, such as a positive temperature coefficient (PTC) resistor, electrically connected in parallel to the sink output. The PTC resistor is typically used to short the CFL output and control the warm-up phase of the CFL. The self-heating of the pTC determines the warm-up time at the CFL output in normal operation. In an embodiment, the temperature dependent resistor is in thermal contact with the at least one led during step d) of the method to provide passive thermal protection of the at least one LED (e.g., via the LED carrier). . When used at excessive temperatures, LEDs are compromised in terms of performance and service life. § When the LEDs are operating overheated, the temperature dependent resistors can be used to reduce the input power to the LEDs. This temperature dependent resistor therefore needs to be. LEDs such as Hai are in thermal contact so that r senses the temperature of the LEDs. This thermal contact may be provided by a heat sink (e.g., a curved portion) or via direct contact with the coffee.

Usually 'once a CFL driver is operating, it is a self-(four) circuit' but the CFL driver requires the __ type of touch to start oscillating. The start circuit of the CFL driver is designed to provide this type of trigger signal. . In an embodiment, the coffee drive is modified during step d) of the method such that the starting circuit can be used to control the amount of energy delivered to the at least one led. This allows the LED light to be dimmed' but can also be used for the temperature protection mentioned above in I59022.doc 201228461. This embodiment is based on the insight that the starting circuit can also be used to stop, for example, to allow PWM modulation of the power signal to the at least one LED. In order to modify the CFL driver, a timer, remote control or power line communication receiver may be provided, preferably provided on the LED carrier board. The on-off switching of the CFL driver for ρψΜ modulation must be performed very quickly to avoid optical artifacts, preferably at frequencies above 400 Hz. The s-CFL driver can be based on an IC (integrated circuit), which is alternatively referred to as a processor. This ic can also be used to control the amount of energy delivered to the at least one LED. A separate temperature sensor can be configured to provide temperature information to the 1C. When a dimming function is required, a dimming signal can be supplied to the Ic. The invention also relates to an LED lamp comprising at least one LED and a CFL driver for driving the at least one LED, the cfl driver being extracted from a CFL (preferably, an integrated CFL). The invention further relates to the use of a CFL driver from a CFL in an LED lamp. Preferably, the CFL driver is from an integrated CFL. These and other aspects of the present invention will be more readily understood from the aspects of the invention. In the like, like reference numerals denote like parts. [Embodiment] FIG. 1 schematically depicts an LED lamp 1 according to an embodiment of the present invention. The LED lamp 1 comprises a lamp housing 3 having a bulb portion 5 and a socket portion 159022.doc •9· 201228461 7. The socket portion 7 includes electrical contacts 9, 11 to electrically connect the LED lamp 1 to a commercial power source (not shown). The socket portion 7 also includes a thread to mechanically connect the LED lamp 1 to the armature and thereby electrically connect the electrical contact point of the socket portion to the electrical contact in the armature 'electrical contact in the armature Point to electrically connect to the mains supply or electrically connect to the mains supply.

The cfl driver can be modified to be suitable for driving the LEDs before mounting the LED carrier on the CFL driver. An advantage of the LED lamp according to the present invention is that the CFL driver 15 and the CFL lamp holder 13 carrying the CFL can be extracted from the finished CFL that still functions properly. This is environmentally friendly because it is not only material but also the functionality of the components being reused. It is much easier to assemble the CFL driver 15 into the lamp envelope 3 by using the CFL lamp holder 13'. In addition, safety precautions taken in the CFL to protect the cfl driver from abnormal operating conditions caused by utility power are also reused in LED lights. Such safety precautions can include a fusible resistor or other component positioned between the CFL lamp holder and the CFL driver. Due to the change from CFL to LED 'cooling requirements may have changed, in this embodiment the heat sink 17 is provided in the form of a larger lamp envelope 3 and the heat sink is thermally connected to the CFL driver and possibly thermally connected To LEd to solve. Figure 2 depicts a circuit diagram of a typical CFL driver prior to modification. The figure includes the connection to the mains power supply PS and to the gas filled tube τ that produces light. The CFL driving circuit includes a rectifier portion composed of diodes di, D3, D4, a resistor R7, and a capacitor C1 that smoothes the output of the rectifier portion. An EMI ferrite portion is provided behind the rectifier portion to minimize interference towards the mains power supply PS. The EMI filter section is composed of an inductor L1 and a capacitor C2. The EMI chopper portion is in turn coupled to a half-bridge inverter comprising transistors Q1, Q2, transformer 159022.doc 201228461 components Tl_a, Tl_b, Tl-c, resistors Rl, R2, R4 , R5, ballast inductor L2 and capacitor C7» The half-bridge converter provides a high frequency switching voltage. The oscillation of the half-bridge converter is triggered by a companion circuit composed of resistors R3, R6, a capacitor C5, a Zener diode D6, and a conventional one-pole D5. When the driver is turned on, the C5 capacitor of the start-up circuit is charged via resistors R3 and R6. At some point in time, capacitor C5 reaches a voltage level 'to cause the Zener diode D6 to collapse, thereby triggering transistor Q2. This starts the oscillation of the half bridge inverter. In steady state operation, the diode D5 repeatedly discharges the capacitor C5 to prevent the starting circuit from triggering the transistor Q2 again. The CFL output of the CFL is electrically coupled to the gas fill tube τ. A capacitor C7 and a PTC resistor are connected in parallel with the tube τ, where pTC represents a positive temperature coefficient. Capacitor C7 and inductor L2 together form a resonant circuit such that capacitor C7 can reach a high voltage that allows the lamp to be ignited. After ignition, the resonant circuit is bypassed by tube T. The PTC resistor determines the warm-up time of the contact points EC 1 and EC2 of the tube T by self-heating of the PTC. Capacitor C4 blocks DC current from passing through tube T. 3 depicts a circuit diagram of an LED lamp partially including the CFL driver of FIG. 2. In principle, the portion of the figure on the left side of the transformer portion 1_3 is similar to the CFL driver' and thus the components have the same reference symbols. However, components can be replaced by similar components that may have other component values. For example, due to current and temperature stress and aging (limited shelf life) during operation in the original CFL, it is known that capacitor C2 has lost part of its capacitance and is resisting 159022.doc 12

Alternatively, an additional capacitor can be connected in parallel to capacitor C2. A new capacitor or additional capacitor can be mounted to the CFL driver, but can also be part of an LED carrier. Although the connection to LEDs LE1, LE2, LE3 may have been made at the CFL output (EC1, EC2, see Figure 2), this embodiment has shorted these contact points EC1, EC2 'by bypassing the diagram 2 PTC and capacitor C7. Between the LEDs LEI, LE2, LE3, a circuit E is provided which is connected to the CFL driver via a transformer consisting of inductors L2, L3, L4. This can be done by winding the inductors L3, L4 around the inductor L2 present on the CFL driver, or the inductor L2 is replaced by a transformer that can be partially or fully placed on the carrier LEDs and The LED carrier board of the circuit. Alternatively, the transformer can be connected to a CFL driver between the inductor 匕2 and the transformer portion Tl_a. The use of the 5 Xuan transformer allows the LEDs to be electrically isolated from the mains supply voltage. If this isolation is not required (for example, because the electrical isolation is provided in the carrier, between the LED carrier and the lamp housing 3 or in the lamp housing; 3), then the CFL driver can be adapted to A simpler configuration of LED operation. For example, a V-tap inductor can be used, ie, no galvanic isolation (gaWanic

In the simplest version, the forward voltages of the LEDs are selected such that no voltage adaptation is required. However, the hunger driver may still need to be modified or expanded by rectification, resistors, z diodes, inductors, capacitors, etc. to match the dynamic characteristics of the LED to the muscle driver. 159022.doc 13 201228461 Circuit E uses diodes 〇7 and 〇8 to rectify the output of the transformer, and capacitor C6 is used to smooth the output of the diodes. The start circuit of the CFL driver can be used to dim the LEDs. By connecting the base of transistor Q2 to ground, the oscillation of the CFL driver is stopped and no power is supplied to the LEDs. The drive will start again by applying a new trigger pulse. If this is done at a sufficiently high frequency, PWM modulation can be used to dim the LEDs. Part of the original CFL start-up circuit can be used for this dimming function, but additional components may be necessary to start and stop the oscillation. An example of a self-oscillating driver is given above in which the power level is affected by pulse width modulation (i.e., alternate start and deactivation of the driver). However, some CFL drives are based on other topologies, for example, based on drive 1C. These driver ICs offer similar possibilities, for example, via shutdown input and undervoltage monitoring (under_v〇hage_1〇〇k 〇ut detecti 或 功率 or power monitoring pins to enable manipulation of signals by the CFL driver (For example, short to ground, applying static or pulsed voltage or current), can also be adjusted to the power transfer of the LEDs. In an alternate embodiment, the PTC resistor is not bypassed and remains in the circuit And thermally connected to the LED so that it can be used as passive thermal protection for the LEDs. 忒 PTC resistors are described as possible as temperature sensors, but other temperature sensor types can also be used to measure the driver, The temperature of the LEDs or any other relevant temperature of the chandelier.
