Hereinafter, various embodiments of a block-type LED driving apparatus according to the present invention will be described with reference to the accompanying drawings.

( 1st Example )

1, the block-type LED driving apparatus 100 according to the first embodiment of the present invention is roughly divided into a driving unit case 110 and a driving unit case holder 150 (hereinafter referred to as a socket) . The driving unit case 110 is detachably attached to the socket 150. The manner of attaching and detaching can be various and is not limited to the various embodiments described below, and various embodiments can be referred to without departing from the technical idea of the present invention.

The driving unit case 110 includes an SMPS driving unit 120 that generates power to be supplied to the LEDs. Functions of each part of the SMPS driver 120 will be described later. The housing of the driving unit case 110 may be made of various materials. As shown in FIG. 2, the driving unit case 110 has a body portion 110 formed at a central region thereof, and a wing portion is formed at both ends of the body portion 110. The SMPS driving unit 120 is inserted and fixed on the upper surface of the body 110 (or the upper surface of the substantially central region of the driving unit case). The central region has a stepped portion compared to the wing portions at both end portions, so that when the elements of the SMPS driving portion are mounted, the height of the wing portion can be made substantially equal to the height of the wing portion. The cross-sectional shape of the wing portion is roughly an 'a' shape.

The wing portions at both ends are formed to have a height difference with respect to a central region (or a body portion) of the driving unit case 110 and are formed of a first wing portion 141 and a second wing portion 142. The first wing portion 141 and the second wing portion 142 have a substantially rectangular shape and a positive electrode 131 of an AC power source is formed on a lower side of the first wing portion 141, The positive electrode 131 of the DC power source is formed at the lower end of the second wing portion 142 and the negative electrode 132 is formed at the other side thereof. The respective electrodes of the first wing portion and the second wing portion are arranged in parallel to each other in the lengthwise or widthwise direction and are respectively inserted or fixed to or supported by electrode coupling portions 171, 172, 173 and 174 described later.

However, the above-described AC electrode units 131 and 132 are described as being composed of two terminals, and they may be composed of three terminals. 3 and 5 show that the AC electrode units 131 and 132 are composed of three terminals. As shown in FIG. 3, the AC electrode unit having three terminals includes a first electrode 132a on the left side of the lower side of the first wing portion 141, and a second electrode 132b on the right side thereof And a positive electrode 131 is provided on the front surface of the first wing portion 141. The three-terminal structure allows the first-electrode 132a and the third-electrode 132b to be held by hand when the user inserts the driving unit case 110 into the socket unit 150, Electrodes 132a and 132b are formed on the left and right sides of the first wing portion 141 (i.e., portions that can be gripped by the user's hand) By providing the electrode 131, electric shock can be prevented in advance. Therefore, the first and second electrodes 132a and 132b, which can be grasped by hand, have a low ground voltage and a potential equal to the user's gripping voltage, and the positive electrode 131 has a high ground voltage, Can be prevented. The three-terminal structure of the AC electrode portion may be configured as shown in FIG. 3 or may be configured as shown in FIG. 5 illustrates another example in which the positive electrode 131 is formed on a part of the groove in the front central region of the first wing portion 141, May be formed. 5 illustrates the first and second wing portions 141 and 142 formed with first and second electrodes 132a and 132b at the left and right ends of the first wing portion 141, + Electrodes 131 are formed on one surface in the same manner as the two-electrodes 132a and 132b. Each of the electrodes is held in contact with or coupled with an electrode coupling portion to be described later to conduct electricity.

3 is a side view of the first wing portion 141 and has a wider width than the second wing portion 142 so that the sizes of the AC electrode portion (or AC supply portion) and the DC electrode portion (DC supply portion) The AC electrode portion and the DC electrode portion are prevented from being inserted incorrectly when the driving unit case is mounted on the socket portion.

FIGS. 4 and 6 illustrate AC electrode coupling portions corresponding to the AC electrode portions of FIGS. 3 and 5, respectively. FIG. 4 corresponds to FIG. 3, and FIG. 6 corresponds to FIG. That is, the AC electrode coupling portion of FIG. 4 corresponds to the case where the positive electrode 131 of the AC electrode portion of FIG. 3 is located on the front side of the first wing portion 141, The electrode coupling portion corresponds to the case where the positive electrode 131 of the AC electrode portion of FIG. 5 is formed by forming a groove in the middle and inner regions of the first wing portion 141.

The AC electrode coupling portions of FIGS. 4 and 6 correspond to a case where the AC electrode portion is formed in a three-terminal structure, and may correspond to the case where the AC electrode portion is formed as a two-terminal hole. In the case of a three-terminal structure, first and second-electrode coupling portions 172a and 172b are positioned on the left and right sides, and between the first and second electrode coupling portions 172a and 172b, And the positive electrode coupling portion 171 is located. Each electrode coupling portion is soldered to the pad of the PCB substrate as shown in Figs. Since the electrode coupling portion is made of elastic or stretchable material, the AC electrode portion is fitted to the coupling portion.

The electrode connecting portions 171 and 172 of FIGS. 4 and 6 are substantially L-shaped, and the lower portion of the L-shaped portion is soldered to each pad, and the portion protruding upward is made of elastic and irregularities, Is supported in contact with the part.

The socket 150 has an insertion area in which the driving unit case 110 is detachably fixed to the socket 150. The socket 150 is attached to one area of the LED circuit board module 500 by various fixing means such as bolts and nuts ). Therefore, the socket 150 is fixed to the LED circuit board module 500, and only the driving unit case 110 is detachably attached to the socket 150. The insertion region 160 in which the driving unit case 110 is inserted or fixed is formed substantially in the longitudinal direction in the central region of the socket 150 and the first wing portion and the second wing portion are formed on both sides of the insertion region 160, 172, 173, and 174 in which the negative electrodes 131, 132, 133, and 134 are inserted and fixed.

Electrode coupling portions 171, 172, 173 and 174 are respectively formed at positions corresponding to each other because the electrodes 131, 132, 133 and 134 of the driving unit case 110 are inserted and fixed. The electrodes are naturally inserted into or engaged with the electrode coupling portions 171, 172, 173 and 174. In the case of the fitting contact, as described above, the shape of the electrode coupling portion may have an "L" shape, and when the electrode coupling portion or the electrode is inserted, the width of the electrode coupling portion or electrode may be larger Elasticity) in the width direction when the electrode is inserted. Alternatively, the electrode itself may have elasticity or elasticity. The electrode coupling portion may be made of an electrically non-conductive material or may be insulated to prevent electrical shorting. Meanwhile, the electrode coupling unit may be made of a material that allows electricity to pass through. In this case, it is preferable that the electrode and the periphery of the electrode coupling unit are surrounded by a material that does not allow electricity to pass therethrough.

The AC electric wires 291 and 292 are drawn into the socket 150 from the LED circuit board module 500 and the AC electric wires 291 and 292 are drawn through the lead grooves 281 and 282 to be electrically connected to the electrode coupling parts 171, 172, 173 and 174 or the electrodes 131, 132, 133, So that the AC power is supplied to the SMPS driving unit 120. The SMPS driver 120, which is supplied with AC power, converts AC into DC, calculates a current required by the LED circuit module 500, and supplies voltage and current to the LED. At this time, when the SMPS driving unit 120 converts AC to DC, the converted DC supplies DC with the same configuration as that of the left AC supply unit. That is, the AC supply unit on the left side is configured to supply the AC power to the electrodes 131 and 132 fixed to the electrode coupling parts 171 and 172 by the AC electric wires 191 and 192 being drawn through the inlet grooves 181 and 182, And the converted DC power is supplied to the LED through the electrodes 133 and 134 and the lead-in grooves 183 and 184 fixed to the electrode coupling parts 173 and 174. [

Accordingly, in the block-type LED driving apparatus 100 according to the first embodiment, AC is supplied through the left AC supply part, and power and current are converted from AC to DC by the SMPS driving part 120 fixed to the insertion area 160 And the converted DC is again supplied to the LED 510 of the LED circuit board module 500 through the DC supply unit. Therefore, the configurations of the AC supply unit and the DC supply unit may have the same configuration.

The electrodes 131, 132, 133, and 134 and the electrode coupling portions 171, 172, 173, and 174 may have a structure in which the electrodes are inserted into the electrode coupling portions, or the electrodes may be in contact with the electrode coupling portions. In particular, in the case of a contact structure, the term " electrode contact portion " may be referred to as an electrode contact portion, and the electrode and the electrode connection portion (or electrode contact portion) are made of the same material. The configuration of the protection portion may further be included. However, in the structure in which the electrodes are inserted into the electrode coupling portion, they may be made of the same material, and the structure of the electrode protection portion may be required. The electrode protecting portion may be wider than the electrode and the electrode connecting portion, so that the electrode and the electrode connecting portion can be inserted into the electrode protecting portion.

When the electrode coupling portion is made of a material that does not allow electricity to flow, a contact point that can be electrically connected to the electrodes 131 and 132 may be formed on the lower surface of the electrode coupling portion, that is, the upper surface of the socket. The contacts are electrically connected to the AC electrical lines supplied through the lead-in grooves 181, 182.

The configuration of the AC electrode unit and the AC electrode coupling unit including the three terminals described above can be similarly applied to various embodiments described later.

However, it may include the following contents having wings as necessary. The electrodes 231, 232, 233 and 234 of the driving unit case 110 are formed at positions corresponding to the electrode coupling portions 271, 272, 273 and 274 formed on the upper surface of the socket 250 on the lower surface of both end regions of the driving unit case 110.

As shown in FIG. 8, the first support portion 241 has first and second support rods 241a and 241b. When the drive unit case 210 is to be fixed to the socket 250, the first and second support members 241a and 241b are lifted upward by pushing the button 241 of the first support unit, The fixing force of the first and second support rods 241a and 241b can be increased by supporting the upper portion of the driving unit case 210 by releasing the button 241 after fixing the first and second support rods 241a and 241b. At this time, the upper and second support rods 241a and 241b may be formed on the upper surface of the socket 250.

The inserted + electrode support rod 341a and the - electrode support rod 341b supply AC electricity to the SMPS driver 320. This configuration and operation are also the same for the second support portion 342 of the DC supply portion on the right side.

[ 14, an insertion groove is formed in the socket 620 in the same manner as the external shape of the driving unit case 610 so as to insert the driving unit case 610. The socket 620 is in contact with the electrode feeding part of the driving unit case 610, An electrode portion 621 is formed. The electrode supplying portion and the electrode portion may be configured to correspond to each other. When the electrode supplying portion is a male, the electrode portion may be formed of a female, and when the electrode supplying portion is a female, the electrode portion may be formed of a male.

Meanwhile, the electrode unit 621 can be divided into the first electrode unit 621a and the second electrode unit 621b. The first electrode unit 621a supplies AC power, and the second electrode unit 621b supplies DC power. That is, the first electrode unit 621a receives AC power from the LED device module 630 and supplies the AC power to the driving unit case 610, and the driving unit case 610 converts the supplied AC power into DC power And the DC power is finally supplied to the LED provided in the LED device module 630 through the second electrode unit 621b.

(SMPS driving part)

The SMPS driving unit 120 is configured as follows. The main control unit may include a rectifying unit, a comparing unit, a switching unit, a variable setting unit, a circuit protecting unit, and an absorbing unit. The rectifying part rectifies the AC commercial power supplied from the outside. Such a rectifying part can rectify the AC commercial power supplied from the outside through an input terminal by converting it into DC. At this time, the rectifying part may include at least one diode element (D1 to D4). That is, the plurality of diode elements D1 to D4 may be formed by a bridge rectifier circuit, but the present invention is not limited thereto, and any circuit may be used in the case of a rectifier circuit that can convert rectified AC into direct current.

The comparator extracts an error between the reference current and the current supplied to the LED through the power source rectified from the rectifying part, and the current supplied to the LED. The comparing unit may include a differential amplifier which calculates an error between a reference current, which is a specified current, and a current that flows through the LED. This differential amplifier may be a negative feedback circuit. The comparator configured as described above can compare the rectified currents supplied on the basis of the preset reference current to easily extract an error. At this time, even if the reference current and the current supplied to the LED are substantially the same, a slight error may be generated. Accordingly, the comparator can operate with an error range that can operate normally considering this point.

The switching unit controls the current supplied to the LED while receiving the error extracted from the comparing unit. The switching unit may be controlled to turn on or turn off while receiving a current output from the comparing unit, while supplying or blocking a current flowing through the LED. The switching unit may include a bipolar junction transistor (BJT) device or a field effect transistor (FET) device.

The variable setting unit sets the reference current supplied to the LED. The variable setting unit may set the current required for the LED in advance or may be set to be changed according to the surrounding environment. That is, the variable setting unit may include a variable resistive element R2 that can easily adjust the amount of current. Since the amount of the current can be easily adjusted by including the variable resistor R2 in this way, it is possible to prevent the voltage drop across the LED from occurring even if the power supply voltage of the AC commercial power supply fluctuates .

The circuit protection part is disposed between the rectification part and the input terminal to which the AC commercial power is supplied, and protects the circuit from an overvoltage supplied from the outside. Such a circuit protection part may be arranged to prevent a circuit from being damaged due to an overvoltage or a surge voltage that can be supplied through an input terminal. Wherein the circuit protection portion may comprise a capacitor element C. [ Since the circuit protection portion includes the capacitor element in this manner, the overvoltage or the surge voltage supplied through the input terminal can be stored in the capacitor, so that it is possible to prevent the overvoltage or the surge voltage from flowing into the circuit in advance.

The absorption part is disposed between the switching part and the LED to absorb the voltage fluctuation. Such absorber can absorb the voltage fluctuation from the output current supplied to the LED. At this time, the absorption portion may include a resistance element R1 that absorbs the voltage fluctuation.

The configuration and functions of the above-described components have been described separately from each other for convenience of description, and any of the components and functions may be integrated with other components or may be further subdivided as needed.
