Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an illumination lamp system,

The present invention relates to an illumination lamp system and a power distributor for the illumination lamp system used therein.

In general, there are incandescent lamps or fluorescent lamps widely used in homes, offices, and the like. Such incandescent lamps or fluorescent lamps have a high power consumption, wasting resources and adversely affecting environmental protection, There is a problem that the electrical resistance of the filament is high and the environmental temperature is increased and the service life of the lamp is short.

Accordingly, in recent years, a lighting lamp using a light emitting diode capable of maximizing a lighting effect with a variety of illumination light and high visibility has been developed and widely used because it has a low power consumption and can be miniaturized, and is economical.

In this case, the light emitting diode (LED) has a structure in which an N-type semiconductor crystal in which a plurality of carriers are electrons and a P-type semiconductor crystal in which a plurality of carriers are holes are bonded to each other, Means a semiconductor device. The light emitting diode refers to a semiconductor light emitting device using spontaneous emission light generated when electrons injected into a PN junction are recombined with holes.

Since the LED has high photoelectric conversion efficiency (lumen / watt), it consumes less power than incandescent bulbs and fluorescent lamps, and does not need preheating time, so it is lighted and turned off fast.

In addition, since the LED has no gas or filament, it is resistant to impact, safe, and has a low power consumption by adopting a stable DC lighting method. In addition, the LED can perform pulse operation and reduce the fatigue of the optic nerve. In addition, the lifetime of the LED is semi-permanent, and it can emit light effects of various colors and can be downsized.

However, there is a problem that the brightness and service life of the LED deteriorate due to heat generated when the LED chip is driven.

In most conventional light emitting diode type illumination lamps, typically a bulb type illumination lamp, a converter, which is a power supply module, is installed in the illumination lamp itself. These converters themselves cause heat generation, are not only vulnerable to heat, but also have a short life span. LED chips, which make up a light-emitting diode-type lighting lamp, have a lifetime of about 60,000 hours, while converters have a lifespan of only 15,000 hours.

Accordingly, despite the fact that the lifetime of the LED chip is still long, if the converter reaches its end of life, the entirety of the illumination lamp or the illumination bulb must be replaced. In fact, a power supply module ('a component included in a converter') having an electrolytic capacitor having a short degradation characteristic, that is, a power supply module, is often caused to fail earlier than the LED chip .

In addition, since such a power supply module is integrated or built-in in an illumination lamp or an illumination bulb, it may be another factor for raising the heat inside the illumination lamp during operation. Also, the power supply unit occupies a certain space in terms of mechanism, which has a disadvantage in that design flexibility is lowered when designing a product. In addition, the power supply module (SMPS) itself occupies more than 20% of the weight of the lighting lamp, thereby increasing the weight of the entire lighting lamp.

In order to solve this problem, in order to remove the power supply module from the illumination lamp or the illumination bulb and simultaneously control the plurality of different LED illumination lamps, it is necessary to use a conventional (integrated or built-in) A power supply technology of a concept different from that of the power supply module of the power supply is required.

Another typical light-emitting diode type lighting lamp is a T-8 LED lighting lamp, which is a rod-type fluorescent lamp type. In the case of T-8, the power supply unit is built-in or external, but when replacing general fluorescent lamp with LED etc. using external type T-8, each power supply module corresponding to one-to-one correspondence with LED etc. is installed separately shall. At this time, when the fixture of the existing fluorescent lamp is to be used as it is, the electric wire connected to the ballast installed in the lamp should be cut off and the power supply module should be installed separately. That is, the replacement cost may be separately generated. Further, when the LED or the like is installed on the ceiling, the workability is deteriorated.

In particular, when the power supply module needs to be replaced after the installation, it is not possible to substitute other specification besides the power supply specified for each LED lighting lamp because the electric capacity (voltage and current) required for each LED illumination lamp is different, The flexibility of the apparatus is deteriorated.

Therefore, in order to facilitate the system management and to separately supply the electric capacity (voltage and current) required by any LED lighting lamp as required, a power distribution device having a different concept from the conventional power supply device is required.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide an LED lighting lamp which improves the stability and life of the LED lighting lamp, facilitates replacement of a general lamp with an LED, And to provide a power distribution device for a lighting lamp system used therein.

6 is a view for explaining an illumination lamp system according to an embodiment of the present invention.

Hereinafter, an illumination lamp system and a power distributor for an illumination lamp system according to the present invention will be described in detail with reference to the drawings.

In this specification, it is understood that the illumination lamp system according to the present invention is applied to an indoor home, but it is not limited thereto, and it is understood that it can be applied to an outdoor illumination system such as a streetlight security system as well as an interior such as a factory or an office something to do.

1 is a schematic view for explaining an illumination lamp system according to an embodiment of the present invention. As shown in FIG. 1, the illumination lamp system, which is an embodiment of the present invention, can be applied to an indoor environment. In this case, the illumination lamp system includes an AC / DC converter 100 (main converter) that receives external 110 V or 220 V commercial power and converts the same into a DC power source, and a DC power source 100 that receives the DC power converted by the main converter 100 A distributor 200 for supplying a rectified current to the illumination lamp 300 and a lamp 300 for emitting light from a power source supplied from the distributor 200. [

At this time, the lamp 300 may be a ceiling-mounted lamp as a light emitting diode lamp. That is, the lamp 300 may be a ceiling-mounted LED lamp installed in each room or living room. The power distributor 200 that supplies power to the LED lamps may include a plurality of buck converters 250 that supply power to the respective lamps.

The plurality of lamps 300 may be the same or different.

In the present embodiment, the lamp 300 is limited to a ceiling-mounted type, but it is natural that the lamp can be installed at a different place such as a wall.

According to an embodiment of the present invention, since it is not necessary to attach a separate power supply module to the ceiling-mounted LED lamp 300, it is possible to facilitate construction when replacing a conventional fluorescent lamp, It is possible to improve the durability of the distributor 200 and the illumination system itself because the distributor 200 is isolated from the LED lamp having a lot of heat and is not likely to deteriorate.

Hereinafter, a specific configuration of the illumination lamp system having the above-described configuration will be described in more detail with reference to FIG.

2 is a block diagram illustrating an electronic configuration of an illumination lamp system according to an embodiment of the present invention.

In this embodiment, an example in which the buck converter 250 is controlled by the controller 400 will be described. In this case, the controller 400 may be formed inside or outside the distributor 200.

2, the illumination lamp system according to the present invention includes an AC / DC converter 100, a distributor 200, a lamp 300, a controller 400, a mechanical controller 410, A switch 420 and a central control system 500.

The AC / DC converter 100 is a component for changing an AC commercial power supply to a DC power supply. Since the LED lamp is usually driven by a DC power source, it is necessary to first change the AC power source to a DC power source.

The distributor 200 is a component for supplying an appropriate constant current power to the plurality of LED lamps 300 installed in each room, as shown in FIG. As shown in FIG. 2, the LED lamp 300 may include a buck converter 250 and a battery 207 that are the same or less than the LED lamp 300. The buck converter 250 is a step-down converter circuit, which is used when the output voltage is lower than the input voltage, and functions to supply a lighting power source to the corresponding lamp 300.

A plurality of distributors 200 may exist, and the distributors 200 may be connected to each other in series or in parallel. A plurality of lamps 300 may be connected to each of the distributors 200. As such, the distributor 200 is expandable.

The buck converter 250 includes a voltage regulator for reducing the direct current power from the main converter 100, a current regulator for rectifying the direct current power supply, a constant current output from the current regulator, And a dimming circuit for adjusting the brightness of the lamp.

The battery 207 is a component for allowing the lamp 300 to be turned on in an emergency state for a predetermined time when the supply of the AC commercial power is limited. That is, if the controller 400 determines that the DC power is not normally supplied from the AC / DC converter 100, the controller 400 supplies the power generated from the battery 207 to the buck converter 250, Is turned on. At this time, the power source is supplied only to the minimum current set so that the light emission of the lamp 300 is performed for the longest time, so that the lamp 300 can be lighted to the minimum. The configuration of the distributor 200 will be described in more detail with reference to FIG.

The lamp 300 is a ceiling-mounted type LED and emits light through a power source from the buck converter 250. In other words, the LED emits light using a constant current direct current power source. In the present invention, since a separate power supply module does not need to be integrated or built-in in the lamp 300, As shown in FIG.

The controller 400 not only controls the operation of the battery 207 as described above but also is connected to the lamp 300 to check whether the lamp 300 is operating normally and also controls the operation of the central control system 500, And sets the output voltage and output current of the buck converter 250 under the control of a home automation system (e.g., a home automation system). The controller 400 may control the lighting power source in consideration of the voltage drop due to the distance when the distance between the distributor 200 and the illumination lamp 300 is inputted through the user input unit 211. [ That is, when installed in a room, when a voltage drop occurs due to a distance between the distributor 200 and the lamp 300, a value lower than the originally required voltage and current (i.e., rated voltage and current) (300). In consideration of this, in the present invention, when the distance between the distributor 200 and the lamp 300 is input through the user input unit 211, the controller 400 automatically adjusts the set voltage of the buck converter 250.

The mechanical adjuster 410 may set the upper limit of the current applied to the lamp 300. For example, the mechanical regulator 410 may be composed of N switches, and the upper limit value of the current limited by each N switches may be different from each other. For example, the upper limit value of the current set by the first switch is a value corresponding to 10% of the maximum value of the current output from the buck converter 250, and the upper limit value of the current set by the second switch is the value It may be a value corresponding to 20% of the maximum value of the output current. According to this method, the upper limit value of the current set by the N switches can be set differently. The upper limit value set by the switch can be variously set according to the convenience of the user or the manufacturer. A detailed description thereof will be described in detail with reference to FIG. 4 below.

As another example, the mechanical adjuster 410 may be a rotary switch that changes its contact point as it rotates. For example, when the rotary switch is in contact with four contact points as the rotary switch rotates, the upper limit value of the current corresponding to the first contact corresponds to 10% of the maximum current value output from the buck converter 250, The value of the current corresponding to the contact may be a value corresponding to 20% of the maximum value of the current that can be output from the buck converter 250. [ According to this method, the upper limit value of the current set by the N switches can be set differently. The upper limit value set by the switch can be variously set according to the convenience of the user or the manufacturer.

In addition to the mechanical adjustments described above, various types of mechanical devices may be used.

The controller 400 may control the operation of the lamp 300 by controlling the distributor 200 to adjust the current value applied to the lamp 300 within the upper limit value range set according to the applied current regulation signal.

By setting the upper limit value of the current to be applied to the illumination lamp by the mechanical control unit as described above, the upper limit value of the current may be changed by the external hacking or the setting of the current upper limit value may be accurately maintained even after the power cutoff recovery, .

The mechanical switch 420 is installed around the lamp 300 and can generate a signal capable of turning on / off the illumination power supplied to the lamp 300. For example, the mechanical switch 420 may be an on / off switch. The mechanical switch 420 may also be installed at any wall around the periphery of where the lamp 300 is installed.

The controller 400 may control the buck converter 250 such that the illumination power is supplied to the lamp 300 in accordance with the on / off signal generated by the mechanical switch 420. For example, when the mechanical switch 420 generates a signal for turning on the illumination power supplied to the lamp 300, the controller 400 controls the buck converter 250 to supply the illumination power to the lamp 300 .

The controller 400 may group the mechanical switch 420 and the lamp 300 according to the setting signal. For example, assume that the configuration signal is to group three lamps located in Region A with a first mechanical switch, and group four lamps in Region B with a second mechanical switch. When the setting signal is inputted, the controller 400 sets the three lamps and the first mechanical switch in the A region to the first group, and sets the four lamps and the second mechanical switch in the B region to the second group .

Accordingly, the user can easily set the illumination power supplied to the lamp 300 by using the mechanical switch 420 installed around the lamp 300, without going to the place where the distributor 200 is installed.

The sensor 430 may recognize motion of objects or sense illumination values. For example, the sensor 430 may be a sensor for detecting movement, a sensor for measuring an illuminance value, and the like.

The controller 400 may control the lamp 300 based on the sensing value generated by the sensor 430. [ For example, if the sensor 430 generates a sensed value that senses the movement of objects in the first area, the controller 400 can turn on the lamp 300 capable of illuminating the first area . Conversely, if the sensor 430 generates a sensed value that senses the absence of movement of objects in the first area, the controller 400 can turn off the lamp 300 illuminating the first area.

As another example, when the illuminance value sensed by the sensor 430 is smaller than the illuminance value, the controller 400 can turn on the lamp 300 set. On the other hand, when the illuminance value sensed by the sensor 430 is larger than the illuminance value, the controller 400 can turn off the lamp 300 set.

Thus, based on the sensed values generated by the sensor, the controller can actively control the lamp, thereby making the lamp more efficient to control.

The central control system 500 is connected to the controller 400 and functions to set the output voltage and the output voltage of the buck converter 250. Thus, resetting the output current and voltage at the central control system 500, when the output voltage and current are replaced with different lamps 300 (e.g., as replaced by LEDs in a fluorescent lamp), the controller 400 , The output voltage and current of the buck converter 250 are reset so that the replaced LED or the like can be normally operated. At this time, the central control system 500 and the controller 400 can be connected through the TCP / IP protocol.

FIG. 3 is a block diagram for explaining the electronic configuration of the distributor 200 among the illumination lamp systems, which is one embodiment of the present invention.

In this embodiment, the buck converter 250 is controlled by the buck controller 220, and the controller 400 may control the buck controller 220. In this case, the controller 400 may be included in a fixed or portable terminal.

3, the distributor 200 includes a plurality of buck converters 250 connected to the lamps 300, a battery 207, a display unit 210, a user input unit 211, a buck control unit 220, and a mechanical adjustment unit 410.

For the sake of simplicity of explanation, the description of the parts explained in Fig. 2 will be omitted.

The output port 270 is a component for connecting the buck converter 250 and the corresponding lamp. The output port 270 may be disposed on the rear surface of the distributor 200 as shown in FIG. So that it is possible to supply various output power using the output port 270. This will be described in detail in FIG.

As shown in FIG. 4, the display unit 210 is a component for displaying the output voltage value set by the user input unit, the output voltage value actually output at the port, and the output current value. Here, the user input unit may be a knob 253 provided for each buck converter, or may be a user input unit 211 installed in the distributor 200 itself.

The buck control unit 220 is connected to the port 270 to check the measured output voltage and the current value and to display the output voltage and the current value set by the controller 400 together on the display unit 210 .

The mechanical adjuster 410 may set the upper limit of the current applied to the lamp 300. The mechanical adjuster 410 may be included in the distributor 200 or may be separately formed.

The buck controller 220 may control the operation of the lamp 300 by controlling the buck converter 250 to adjust the current value applied to the lamp 300 within the upper limit value range set in accordance with the applied current control signal.

The mechanical switch 420 is installed around the lamp 300 and can generate a signal capable of turning on / off the illumination power supplied to the lamp 300. For example, the mechanical switch 420 may be installed on a wall that is in the periphery of where the lamp 300 is installed.

The buck control unit 220 may control the buck converter 250 such that the illumination power is supplied to the lamp 300 in accordance with the on / off signal generated by the mechanical switch 420.

The controller 400 receives the setting value for the illumination lamp system and inputs the set value to the buck control unit 220. The set values for the illumination lamp system may be input via a user input (not shown) connected to the controller 400. For example, the controller 400 may be a configuration included in the computer. After connecting the computer and the distributor 200, the user can input a desired set value through the computer. In this case, the controller 400 of the computer may apply the input set value to the buck control unit 220. The buck controller 220 stores the input set values and controls connected components according to the input set values. After the set value is input to the buck control unit 220, the user or the system administrator can separate the computer and the distributor 200. In this way, the user can input the set value by connecting the computer and the distributor 200 for convenience.

Alternatively, the user may input a setting value for the illumination lamp system through the user input unit 211. The buck controller 220 stores the input set values and controls connected components according to the input set values.

Hereinafter, the outline of the distributor 200 having the above-described structure will be described in detail with reference to FIG.

4 is a view for explaining the appearance of the distributor 200 among the illumination lamp systems according to one embodiment of the present invention. As shown in the figure, the distributor 200 includes a rack having a plurality of compartment spaces, and a buck converter 250, which is replaceably installed in each compartment space, is provided. The buck converter 250 is provided with a buck converter switch 251 for controlling operation on one side and a knob 253 for controlling the output current and voltage and an output port 270 . The buck converter switch 251 controls on / off of the buck converter 250.

The mechanical adjuster 410 may set the upper limit of the current applied to the lamp 300. For example, the mechanical regulator 410 may be composed of N switches 430 to 439, and the upper limit values of the currents limited by the N switches 430 to 439 may be different from each other. For example, the upper limit value of the current set by the first switch 430 is a value corresponding to 10% of the maximum value of the current output from the buck converter 250, and the upper limit value of the current set by the second switch 431 is And has a value corresponding to 20% of the maximum value of the current that can be output from the buck converter 250. The upper limit value of the third switch 432 to the ninth switch 438 also has an upper limit value of the current at the same interval. Finally, the upper limit value of the current set by the tenth switch 439 has a value corresponding to 100% of the maximum value of the current output from the buck converter 250.

Accordingly, the user or the manager can mechanically set the upper limit value of the current applied to the lamp using the mechanical adjustment unit 410. [

According to this method, the upper limit value of the current set by the N switches can be set differently. The upper limit value set by the switch can be variously set according to the convenience of the user or the administrator.

Here, the knob 253 is a component for varying the resistance value. As the knob 253 is rotated in one direction, the resistance value connected to the output port is changed, thereby changing the output voltage and the output current . By using the knob 253, appropriate power (voltage and current) can be supplied to the lamps 300 of various kinds.

Instead of this knob, a plurality of resistance terminals (not shown) may be attached to the substrate of the buck converter 250 (i.e., the substrate on which the voltage regulator, current regulator, and dimming circuit are mounted). The resistor terminal is configured to be connected to the output port 270. The designer can adjust the output current by combining the resistor terminals so as to match the input power value of the corresponding lamp.

This buck converter 250 serves to supply power to the voltage and power set for the corresponding lamp 300, as described in Figures 1-3.

On the other hand, a display unit 210 for displaying a set output voltage, a current, a measured output voltage and a current is installed on one side of the distributor 200, and a user input unit 211 is provided below the display unit 210, So that the output voltage and current can be set.

Meanwhile, the buck converter 250 is mounted while being slidably mounted in the partition space of the rack. Accordingly, when the buck converter 250 fails, the entire lighting system can be normally repaired by exchanging only the corresponding one, so that the exchange cost and the management cost can be remarkably reduced.

Since the output of the buck converter 250 can be set to an input device provided in the knob 253 or the distributor 200 installed in the buck converter 250, The output of the buck converter 250 can be conveniently set.

Hereinafter, the output port 270 provided in the converter or the distributor 200 will be described with reference to FIG.

5 is a rear perspective view of a distributor for explaining an output port (power port) of the distributor among the illumination lamp systems according to an embodiment of the present invention. 5, the output port 270 provided on the rear surface of each buck converter 250 may include a first sub output port 271 and a second sub output port 272.

The first sub output port 271 may be configured to output the first sub output power and the second sub output port 272 may be configured to output the second sub output power by the buck converter 250 .

The first sub output power and the second sub output power may be different from each other. Accordingly, when the lamp 300 is installed, the sub-output port matching the input power value of the lamp 300 is determined and the connection port of the lamp 300 is connected to the lamp 300 so that the lamp 300 and the distributor 200 are connected . When the input power of the lamp 300 is equal to the sum of the first sub output power and the second sub output power, the first sub output port 271 and the second sub output port 272 are connected to each other using the special gender, And the sum of the first sub output power and the second sub output power is output.

Alternatively, each output port 270 may be combined to output the summed power. That is, by connecting two or more output ports 270 to the corresponding lamp 300 at the same time, it is possible to supply the summed power to the lamp 300.

With the above configuration, it is easy to cope with a lamp that requires various input powers.

Although the example of two sub output ports has been described in the present embodiment, the present invention is not limited to this, and it is possible to provide various output powers by using three or more sub output ports.

6 is a view for explaining an illumination lamp system according to an embodiment of the present invention.

6, the illumination lamp system according to the present invention includes a distributor 600, mechanical switches 610, 611, 612, and a controller 620. [

In this embodiment, the controller 620 will be described separately from the distributor 600, but it is obvious that the controller 620 can be formed inside the distributor 600. [

The distributor 600 is a component for supplying an appropriate constant current power to a plurality of LED lamps (not shown) installed in each room.

The divider 600 may include a first buck converter 601, a second buck converter 602, and a third buck converter 603. The first buck converter 601 can supply illumination power to the lamps installed in room 1 and the second buck controller 602 can supply lighting power to the lamps installed in room 2, The converter 603 can supply power for illumination to the lamps installed in the room 3. [

The first mechanical switch 610 may be installed around the lamp installed in the room 1 and may generate a signal capable of turning on / off the illumination power supplied to the lamp.

For example, when the first mechanical switch 610 generates a signal for turning off the illumination power supplied to the lamp, the controller 620 determines that the first buck converter 601 does not supply the illumination power to the lamp .

For example, when the second mechanical switch 611 generates a signal for turning on the illumination power supplied to the lamp, the controller 620 causes the second buck converter 602 to turn on the illumination power to the lamp .

Accordingly, the user can use the mechanical switches 610, 611, and 612 installed in the periphery of the lamp to illuminate the lamps located in the rooms 1, 2, and 3, respectively, The power source can be easily controlled.

According to an embodiment of the present invention having the above-described configuration, by isolating the illumination lamp and the power supply module, it is possible to prevent the distributor, which is a power supply module, from being damaged by heat, The power supply module is not attached. Therefore, when the illumination lamp is a ceiling mount type, the stability can be improved, the installation can be facilitated, and the weight of the illumination lamp can be reduced.

Further, according to the embodiment of the present invention, since the distributor includes a plurality of exchangeable buck converters, the maintenance becomes easier when the capacity per illumination lamp is different.

The above-described illumination lamp system and the power distributor for the illumination lamp system used therein are not limited to the configuration and method of the above-described embodiments, but the embodiments may be applied to various embodiments It is needless to say that all or some of these elements may be selectively combined.
