Therefore, for the latest, most power-saving and most forward-looking environmental protection lighting technology-the electro-optical characteristics of white light LEDs and their lighting applications, naturally Is interested in and spare no effort in research and development design. [New Content] 10 Therefore, the purpose of the present invention is to provide a remote dimming control device that can be applied to white LED lighting fixtures and can adjust the luminous intensity. Therefore, the novel remote-control dimming control device is suitable for controlling a white LED lighting fixture.

The constant current driving unit has a driving circuit connected to and controlled by the main control unit, and a constant current circuit driven by the driving circuit to output 20 M252234 current to the white light LEDs of the lamp. The driving circuit is Controlled by the main control circuit according to different control signals, the constant current circuit is accordingly driven to selectively output different constant current values to the white light LED. 5 The effect of this new model can be achieved by pressing and controlling the control signal issued by the transmitter ′ through the receiver and selectively outputting different currents to the light-emitting unit ′, so that each white LED of the light-emitting unit obtains a dimming effect. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. As shown in Figs. 1 and 2, the preferred embodiment of the new remote control dimming control device can be used to control a white LED lighting fixture 2. The white-light LED lighting fixture includes a plurality of light-emitting units 21, and each light-emitting unit 21 has a plurality of white LEDs 211 connected in series. The remote light control device includes a transmitter 3 for emitting an infrared control signal, and a receiver 4 for receiving an infrared control signal. The infrared transmitting circuit preset in the transmitter 3 is shown in FIG. 3, and its-button 31 can be operated by pressing, and an infrared control signal is emitted through its two infrared light emitting diodes 20 32 (IR LED). Since the operating principle of the infrared transmitting circuit for transmitting control signals is very common, it will not be described in detail here. It can be seen from ® u 2 'The receiving 11 4 includes-an infrared receiving circuit 41 for receiving signals,-to provide control The main control unit 42 and 7 M252234 of the function control and drive the constant current drive unit 43 of the white LED lighting fixture 2. The receiving circuit 41 is used for receiving the infrared radiation emitted by the transmitter 3 to control the signal. Similarly, the operation principle of the receiving circuit 4 丨 for receiving the control signal is also very common, and will not be described here, and its circuit diagram will not be disclosed. The main control unit 42 of the province establishes its required action program by programming. , And is connected to receive the control signal received by the receiving circuit 41 to execute its preset action program. 10 The constant current driving unit 43 has a plurality of driving circuits 43 1 connected and controlled synchronously by the main control unit το 42 and a plurality of constant current circuits 432 driven by the driving circuits 431 respectively. The driving circuits 431 are controlled by the main control circuit 42 according to different control signals, and the constant current circuits 432 are accordingly driven to selectively output different currents to the light emitting units 21 of the lamp 2. In this embodiment, each driving circuit 431 has five groups of light-emitting diodes 433 and photoelectric crystals 434 coupled. The light-emitting diodes 433 are controlled by the main control circuit 32 to be turned on and off, and then control the corresponding The optoelectronic crystals 434 are turned on, and the driving circuit 431 selectively drives the corresponding constant current circuits 432 to output different constant current values by using the photonic crystals 434 with different conduction combinations. As shown in Figures 2 and 4, in this embodiment, each constant current circuit 432 is a transformerless constant current drive IC (integrated circuit) of type MBI6001. Its operation can be input to the mains AC power supply VAC and rectified into a pulsed constant current. Input 8 M252234 5 output, the height and width of the current pulse can be adjusted. The duty cycle and height of these pulses can be adjusted by adjusting the resistance value of R2 and R2 to achieve the desired output current. Because the constant current ㈣q and constant current output, the total voltage of 12 is not a fixed value, which is roughly changed with the number of serially connected output terminals: light LED 211. The total output current is equal to the η The number is multiplied by the forward voltage. When driving the IC with a large output UV, 'If the forward voltage of the white LED is 4V, the number of LEDs that can be connected in series is 15. 10 There are two ways to adjust the constant current value of the constant current circuit 432.-Adjusting the R1 value can change the duty cycle to achieve the average current adjustment = effect. T The smaller the R1 value, the shorter the duty cycle, and the more average current Small; square = two: adjust R2 resistance value, you can choose different peak currents, and change the average current value. When the R2 value is smaller, the peak current is larger, and the average current is larger. 15 In this embodiment, the resistance value of R2 is set to 0, and the resistance value of ri is the conduction group of the corresponding photonic crystal W of the circuit 431. There are five photonic crystals 434 in the driving circuit 431. Predetermined = Connect the four dimming resistors ⑽ ~ ⑽ to the output terminal of the third to third optoelectronic crystal 434 from the top to the bottom to form the aforementioned magic. The end is connected in series with the white light = D211 of the corresponding light-emitting unit 21 as a switching function, and the fifth photoelectric crystal 434: the output end is connected in parallel. The input end of the light-emitting unit 21, which is connected to the _6001 Between pin 3 and pin 6. : The above-mentioned first to third optoelectronic crystals W have different conduction combinations, and the equivalent resistances formed by connecting the withered resistors R11 to R14 will be rectified and changed, and the equivalent resistance is actually The aforementioned R1. In addition, as long as the fourth photo-crystal 434 is not turned on, the corresponding light-emitting unit it 21 will be in the off state. When the fifth photo-electric crystal 434 is turned on, the corresponding light-emitting early-stage 21 can be short-circuited to make it stable. About the constant current circuit 该 of the receiver 4 in this example, it can selectively output different constant current values, and the points are detailed as follows. 10 " 1 'The lamp 2 is off. When the transmission n 3 is not operated according to the money and the receiver 4 has not received the control signal of the transmission II 3, the main control unit 42 of the receiver 4 has a built-in program to control the first to fourth photoelectric crystals of the driving circuits 431 = Non-conducting, the resistance value of R1 of MBI6 () () 1 is equal to magic 4, the corresponding light-emitting early 21 is in an open state, and the fifth photo-electric crystal 434 is turned on to short out pin 3 and pin 6, at this time, The white LEDs 211 of the corresponding light emitting unit 21 are not turned on. 15 20 2. Lamp 2 emits the first brightness ... When the key 31 of the transmitter 3 is pressed first: the receiving circuit 41 of the receiver 3 receives the control signal and transmits it to the main control unit 42, the main control unit 42 only The fourth and fourth photoelectric crystals 434 are controlled to be turned on. At this time, the constant current circuit ri is equal to the core and the core, and outputs a ϋ current to the corresponding light-emitting unit & 21. Therefore, the white SLEDs 211 of the light-emitting unit 21 light up. This is called the first brightness. 3, the second brightness of the lamp 2 ... When the key 31 of the transmitter 3 is pressed, the receiving circuit 41 of the second temple receiver 3 receives the control signal and transmits it to the main control unit 42, the main control unit 42 only controls the second, The four photoelectric crystals are turned on. At this time, Ri of the constant current circuit 432 is connected in parallel and outputs a mth. The resistance value of R12 in parallel with R14 is greater than the first 10. The white LEDs 211 of the light emitting unit 21 corresponding to the aforementioned first constant current emit a second brightness, of course, the second brightness is brighter than the aforementioned first brightness. 4. Luminaire 2 emits the third brightness: When the key 31 of the transmitter 3 is pressed first, the receiving circuit 41 of the receiver 3 receives the control signal and transmits it to the main control unit 42. The main control unit 42 only controls the third, The four photoelectric crystals 434 are turned on. At this time, R1 of the constant current circuit 432 is equal to Ri3 and rm in parallel, and outputs a third constant current. The resistance value of R13 in parallel with R14 is greater than the aforementioned R12 in parallel with R14, that is, the third constant current is greater than The aforementioned second fixed current corresponds to the third brightness of the white LEDs 211, which is brighter than the aforementioned second brightness. 15 5. Luminaire 2 emits fourth brightness ... When the key 31 of the transmitter 3 is pressed for the fourth time, the main control unit 42 controls only the fourth photo-electric crystal 434 to be turned on. At this time, R1 of the constant current circuit 432 is equal to R14, and Output_fourth, because R14 is greater than Rl3 in parallel with R14, the fourth constant current is greater than the third constant current, and the white LEDs 2U correspond to the fourth brightness, which is brighter than the third brightness. 20 6. The lamp 2 does not light up ... When the button 31 of the transmitter 3 is pressed for the fourth time, its state is cycled to the aforementioned one! In the case of g, the fifth light t434 of the main drive circuits such as 434 is in an open state, so the white LED 211 is off. As mentioned above, the design of this new type of remote control dimming control device can receive white light in a predetermined range by pressing the control signal sent from the operating button 3 of the transmitter 3 through the receiving circuit 41 of the receiver 4 to perform white light. 11 M252234 The brightness adjustment of the LED lighting fixture 2 uses the main control circuit 42 of the receiver 4 to control the constant current drive unit 43 according to different control signals, so that each drive circuit 431 in the constant current drive unit 43 drives accordingly. The corresponding constant current circuit 432 selectively outputs different currents to the respective white light LEDs 211 of the corresponding 5-light-emitting unit 21 to obtain the effect of adjusting the luminous intensity. Therefore, the purpose of the present invention can be achieved. However, the above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited in this way, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new application and the content of the new specification, Both 10 should still fall within the scope of this new patent.
