Description

[Technical field], the body is related to the use of LED (Light Emitting Diode; light emitting diode) to perform display or lighting of the lighting device, and in particular to the LED lighting device can be directly connected to the AC power supply . [Background technique]

Various types of indicator lights used in office buildings, residential buildings, and public buildings, such as fire hydrant lights, emergency lights, or operation button lights for ticket machines, vending machines, elevators, etc. Incandescent lighting using tungsten filament lamps. In addition, incandescent lamps are still the mainstream for indoor lighting appliances. " On the other hand, due to the progress of semiconductor device technology in recent years, from the viewpoint of the types of light colors, brightness, durability, and power consumption (luminous efficiency), LEDs can not only achieve performances that surpass those of incandescent lamps, but The current situation is that almost no incandescent lighting is used for the aforementioned applications. The premise of performing display or lighting is that it is usually connected directly to a commercial AC power source (domestic in Japan: 100 volts, the United States: 110 volts, and Europe: 230 volts).

That is, LEDs, as is well known, operate with a power supply voltage of direct current (DC) number v. Therefore, in the conventional use, it is necessary to convert a commercial AC power supply to a power supply device of DC number V, and the LED lighting device On the whole, it has become South-priced and large-scale. Based on this fact, due to the shortcomings of knowledge, anyway, it is necessary to try to directly connect LEDs to commercial AC power. Here, use the drawing surface to

Diode), 1 06 is LED lighting. However, 108 is the AC input terminal H (H0T LINE), and 109 is the AC wheel input terminal C (C00L LINE). The AC input voltage is commercial. In this LED lighting lamp 106, the anode is connected to a bridge-type full-wave rectifier through a constant current element (CRD1) 105, a series resistor 104, and a Zener body 103 showing the polarity in series. With the positive output terminal of the diode 102, the cathode is directly connected to the negative output terminal of the same-bridge diode 102. The LED lighting lamp 106 is composed of one or a plurality of LEDs connected in series. However, the circuit portion other than the LED lighting lamp 106 constitutes a power supply device (the same applies to the following embodiments). Next, the operation of the first embodiment will be described with reference to FIG. 2. Figure 2 is the voltage waveform diagram of node A107 and node with 081 in the first figure. In the figure, the vertical axis represents voltage (v), the horizontal axis represents time (t), and 201 represents the voltage of node A1 07. Waveform, 02 indicates the voltage waveform of the node at 081. The peak value of AC input voltage is about 14v, and the Zener voltage Vz of Zener diode 103 is 100V.

It can be understood from Figure 2 that the AC input voltage 100V is rectified by full-wave rectification with the bridge diode 102, and the full-wave at 〇〇〇Hz by the Zener diode During the period of 100V or more of the rectified waveform, the LED lighting lamp 10 is turned on (on and off).

Description of the invention (12) The duty cycle of ON and OFF is 6: 4 (100 Hz), in order to achieve high efficiency (low loss) of electric power in the range where the light does not feel flicker. The peak value of the voltage applied to the LED lighting lamp 106 is because the voltage applied to the lighting lamp 106, the constant current element 10, and the series resistor 10 is only a part that exceeds the Zener voltage, so Approximately 40 volts. A constant current is applied to the passing current of the LED lighting lamp 106, and the constant current element is used. Fig. 3 'is a circuit diagram of the second embodiment of the power source device and the LE]) lighting device according to the present invention.

Here, FIG. 3 is a capacitor (C1), 304 and 305 are voltage-dividing resistors (R1, R2), 306 is a power supply line, and 307 is a current measurement circuit (I DET). , 308 is a GND (ground) line, 309 is an input voltage measurement circuit (VDET) corresponding to zero crosss, 31 is an oscillation and frequency division circuit (Osc · Div), and 311 to 313 are action lines. 314 is a power supply 2VddL line, 315 is an inductor (coil), 316 is a switching element made of N-channel MOSFET '3 1 7 is a flywheel diode, and 3 22 is a switching control circuit (SWCO). Others, in Figure 3, are the same as ^; the road; show the same or a considerable part.

Here, the resistors 304 and 305 are connected in series, and the output voltage of the bridge full-wave rectification diode 102 is divided, so the voltage division point is connected to the input of the input voltage measurement circuit 309. Terminal and oscillation and frequency division, the power supply input terminal of the road section 310 and the power supply system are 2 ¥ (1 (^ line 314. 'capacitor 3 0 3'), which is connected between the same voltage dividing point and ground. LED lighting lamps 106, The inductor 315 and the switching element 316 are connected in series and are inserted between the power line 1VddH line 306 and the ground line 308, and

496104 V. Description of the invention (13) The current measurement circuit section 307 is inserted into the lVddH line 30 6 of the power supply system. The LED lighting lamp 106 'is formed by connecting 2 to 8 LEDs in series. The flywheel diode 317 is connected in parallel to the series circuit of the LED lighting lamp 106 and the inductor 3 15. The switching control circuit section 322 receives the operating power from the power supply line 2VddL line, and receives signals from the current measurement circuit section 307, the input voltage measurement circuit 309, and the vibration / frequency division circuit section 3 10. To control on · OFF control as described later. Next, the operation of the second embodiment will be described with reference to FIG. 4.

y Figure 4 'is the voltage waveform diagram of node A107 and node B321 in Figure 3. In the figure, the vertical axis represents voltage (v), the horizontal axis represents time (t), and 40i represents the voltage waveform of node A107. 4〇2 represents the voltage waveform at the node 0

The peak value of Αγ input voltage is about 14 volts. Here, when the input voltage (Lang point A107 voltage) rises from 0 V to 40 volts, the control circuit section 32 is switched and the second over-peak value drops to 40. At time v, the same control circuit unit will lose j = 20.04 and 30.5 centimeters of point voltage (power supply system ... several lines μ.), so the control circuit unit 322 is switched, and the voltage is also 5V. Solution, in This AC input voltage is 0V in a bridge type: ΪΪ Γ current, and the switching control circuit section 322 is used to check the frequency of all the above-mentioned switching elements 3 1 6 0N, 0FF ★ frequency, that is, the LED lighting lamp 1 (system (PWM button, d) The upper switch element 3 16 is turned on and off by the old system (PWM, system), and the illumination lamp ι〇6 is turned on and off.

496104 V. Description of the invention (14) The frequency of ON and OFF, which is in the range of 400 watts, high power efficiency (low loss, t seek to pass the LED lighting without feeling flicker when emitting light 丨 〇6 The electric part 322 determines the electric power generation, and P | seeks to change the load (the number of LEDs of the control circuit by the switching control circuit) to change the load (which constitutes the UD lighting lamp 106): the same current is passed. On the capacitor 303 ', a resistor of 3 is used. 4, 3,05 to divide: In order not to exceed the applied 5V, so it can cope with the low withstand voltage of 31. It can measure the power supply function of the unit 322 with the input voltage. "May respond to the so-called" Produced by Dingxue 4b ΛΑ 0 -r, in Taixing 丨 Electric motor ", the fixed average current of the deducted 疋 2, and the 2: 2 are switched using the oscillating circuit part, so for example, 2 months: t 疋 current At that time, if the peak current is 30m, and it is driven with a 30% duty cycle, the average is 10mA. As a light-emitting application of LED, it is not the driving method that it hopes. The reason is that for people, The brightness of the LED's current and brightness characteristics are not linear (Unear) = a characteristic of super linear For example, under the condition that the current is 2 times, the degree is not equal to 2 times and is η times the power of 2 (n is 1 or more). This is because the brightness of the human eye remains at the peak value. As an image, 2 is driven by setting the peak current to a duty cycle that is lower than the DC current formed by the same average current (commonly referred to as "pulse drive". It will feel brighter. If you use such a pulse drive, you can Get the same perceived brightness with less power. But if you get the same perceived brightness, if you do n’t drive it with pulses above 100 Hz, you will feel the flicker.

2116-4110-PF; ahddub.ptd Page 17 496104 V. Description of the invention (15) The flicker does not match, so it is hoped that the pulse drive is above 100Hz. Such a pulse drive is also effective in the third and fifth embodiments with an oscillating circuit described later. In the fourth and sixth embodiments, although there is no vibrating circuit section, as long as it operates at 100 Hz or higher, it is still the same. effective. Here, the power supply system 2Vdd is simply constituted by resistance division. Of course, by constructing (or using) another type of power supply circuit that can be operated (switched, etc.), the operation is stable and convenient. Here, for the input peak voltage of 140V ', the operation start input voltage VDET is set to 40V, but for such an input, VDET is set to a number of 10% or more, and it is not necessary to make the 0N / 0FF ratio of the switching regulator ( The duty cycle) is extremely small (as small as several%), and it is easy to ensure the tolerance on the circuit design. On the other hand, as mentioned before, if the frequency is switched, if the VDET is particularly increased, the AC frequency will be flickered, for example, 100 Hz, and the flicker will be felt by the naked eye when the frequency is, for example, less than 5011. In this case, by reducing the operating input voltage VDET to 3 ~ 40V, even if the AC frequency is below 50Hz9, there is no need to worry about flicker, and you can make it operate. However, at this time, it caused an extremely reduction in the duty cycle (the minimum became a few% or less, and a few spike-like pulses). The design tolerance of the above circuit requires the characteristics (DC resistance component) or moon-cutting (speed) of the inductor elements used in this production condition to become high-performance characteristics.仵, in the original use of each element (component) to a certain degree of high VDET is 3 ~ 40V, without worrying about the dynamic range of the work cycle (= 1, making spikes) or worrying about the AC frequency, Rather, the action of VDET is helpful for the stable operation of the oscillation circuit section or the switching control circuit section.

In addition, the same symbols in FIG. 6 ′ and FIG. 3 indicate the same or equivalent parts, but here, the switching element 316 is made of a 1 ^?

On the other hand, the current detection circuit section

Hi is on the negative output side of the bridge diode 102 as described above. A sense 315 is inserted between the switching elements 316 and 106 made of the transistor, and the series resistor 621 is inserted between the inductor 3 15 and the LED lighting lamp 106. The output voltage measured by the dry circuit 609 'is controlled in the same manner / 2: the measured value of the input voltage is transmitted to the switching control circuit 322.

That is, the input voltage measurement circuit 609, because the output voltage of the led lighting lamp remains one thunder = at first, in order to work together, so for example, 3 out of 2 regulators to move the led lighting lamp as shown in Figure 6 is " At this time, if the electrical waste is 16V and 2V. In other words, when the output of thunder and voltage is 0mA, the round-out voltage becomes a current operation. When the output power is between 2V ~ 16V, it becomes a fixed power, and In the third embodiment, either the switching element 31 6 M0SFET or the PNP type M0SFET.

Description of the invention (28) AC input terminals 1 604a, 1 604b and LED lighting module power terminals 1 604c, 1 604d (similar to the solder joints on the substrate 1601) are arranged as shown in Figure 17 . This configuration can also be as shown in FIG. 8 or FIG. 9. That is, the power terminals 1604c and 1604d of the LED lighting module are installed beside the LED lighting module 1503, and are separately arranged inside and outside the substrate 1601 as shown in the figure. The AC input terminals 1604 & 160b, as shown in Figs. 17 to 19, are arranged in a position before and after leaving the housing section 1 & 02 (the "up and down direction" in the figure).

Embodiment 7 will be described with reference to FIGS. 20 and 20. And on the circuit diagram of FIG. 20 and the circuit diagram of FIG. 22 of the embodiment related to the following description, the same symbol is attached to the same part to omit the detailed description of this part. As shown in FIG. 20, in Embodiment 7, in the bridge rectification diode provided between the AC input terminal 108 and 107, the constant current element 105 and the LED lighting lamp are provided. 106 is connected in series, and a Zener diode 20 01 is connected in parallel to the LED lighting lamp 106.

2116-411〇-PF; ahcldub.ptd Page 31 496104 V. Description of the invention (29) When the predetermined voltage VF is reached, because the current flows to the Zener diode 2 01, the LED lighting 106 is being prevented At the same time when the light is dark, the excessive current flows to the LED 106, and the current flows to the Zener diode 20 01, so it can protect the LED 106 when the excessive current flows. That is, as shown in the relationship between the current and voltage of the LED lighting lamp 106 and the Zener diode 20 01 shown in FIG. 21, in the region S, the voltage is lower than that of the LED lighting lamp 06. The voltage VF is small, so the LED lighting lamp 06 should not light up as usual, but even if the switches of the AC input terminals 108 and 107 are turned off, there are several μA due to high impedance (for example, 100 to 500 // A) current flows to the circuit. However, in the related constant current area S, the current is leaked on the Zener diode 200 1 and does not flow to the LED lighting lamp 106, so it can prevent dark lighting. On the other hand, when the current is about 10 mA and the VF of the LED lighting lamp 106 exceeds a certain voltage range W (for example, 2V to 3V), the LED lighting lamp 106 is turned on, and once the current I becomes If an excessive current exceeds the range w, this excessive current flows to the Zener diode 2000. Therefore, while preventing dark lighting, it is possible to protect the LED lighting lamp 106 from excessive current. In the seventh embodiment, the Zener voltage of the Zener diode 2 0 1 is 100% higher than the VF (forward voltage drop) of the LED lighting lamp connected in parallel to the Zener diode. The range above 30 is below. When it is smaller than 10%, it is impossible to effectively prevent dark lighting, and when it exceeds 30%, it is impossible to sufficiently protect the LED lighting lamp 106 with excessive current. Fig. 22 shows the eighth embodiment. In Embodiment 8, a plurality of LED lighting lamps 106 (each LED lighting lamp may also be a unit of a plurality of LED chips) are connected in series, and a Zener diode 200 1 is connected in parallel to each LED lighting.
