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.

Background Art [0002] Lighting lamps widely used in general households and offices include a bulb or a fluorescent lamp. Such a bulb or a fluorescent lamp consumes resources because of high power consumption, and not only hinders environmental protection, but also easily generates heat There is a problem that the environmental temperature is raised to cause the service life of the lamp.

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, Refers to a semiconductor light emitting device using spontaneous emission light generated when electrons injected into a PN junction and holes are recombined.

Such LEDs have low power consumption due to high photoelectric conversion efficiency, so that they generate less heat and are not thermally dischargeable. Therefore, they do not need preheating time, and they are turned on and off quickly.

In addition, since there is no gas or filament, it is strong against shock, safe, and adopts the stable direct current lighting method, it is possible to reduce the power consumption, it can perform repetitive pulse operation and reduce the fatigue of optic nerve, It is possible to produce a lighting effect of color, and miniaturization is possible by using a small light source.

However, such an LED has a problem that affects brightness and service life due to heat generated when the LED chip is driven.

In most conventional light emitting diode type lighting devices, a converter, which is a power supply module, is installed in a lighting device itself. The converter is not only vulnerable to heat but also has a shorter life span than an LED bulb. That is, while a light emitting diode type illuminator has a life of approximately 60,000 hours, the converter has a lifetime of only 15,000 hours.

Accordingly, despite the lifetime of the LED chip, the life of the converter is shortened, and the entire lighting apparatus must be replaced. A power supply unit including an electrolytic capacitor or the like having a very short characteristic is often caused to fail earlier than an LED.

Further, when a general fluorescent lamp is replaced with an LED or the like in order to reduce power consumption, a power supply module is required for the LED itself, so that the replacement cost is increased. Further, when the LED is attached to the ceiling, There is a problem that the weight becomes heavy due to the driving module and the installation cost becomes high.

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.

FIG. 1 is a view for schematically explaining an illumination lamp system, which is an example of the lighting 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 to a DC power source, and a DC power source A distributor 200 for supplying a rectified current to the illumination lamp 300 and a lamp 300 for emitting light 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.

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. 2, the illumination lamp system according to the present invention mainly comprises an AC / DC converter 100, a distributor 200, a lamp 300, a controller 400 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 the same number of buck converters 250 and a battery 207 as shown in FIG. 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.

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 turning on the lamp 300 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. That is, 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 attached to the lamp 300, it can be constituted by only the LED substrate and the frame.

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). When the distance between the distributor 200 and the illumination lamp 300 is inputted through the distributor input unit 211, the controller 400 can control the lighting power source in consideration of the voltage drop according to the distance. That is, when the lamp 300 is installed indoors, the distance between the distributor 200 and the lamp 300 is large, so that when a voltage drop occurs, a value lower than the originally measured voltage and current (i.e., the measured voltage and the measured 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 distributor input unit 211, the controller 400 automatically adjusts the set voltage of the buck converter 250.

In the present invention, the buck converter 250 is controlled by the controller 400, but it should be understood that the buck converter 250 may be controlled by the buck controller 220 as shown in FIG. 3 .

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. The divider 200 includes a plurality of buck converters 250 connected to the lamps 300 and a battery 207, a display unit 210, a distributor input unit 211 and a buck control unit 220, .

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 and the output voltage value set by the user input unit, and the output voltage value and the output current value actually output from the port. Here, the user input unit may be a knob 253 provided for each buck converter, or may be a distributor 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 .

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, the distributor 200 is formed with a rack having a plurality of compartment spaces, and each of the compartment spaces is provided with a buck converter 250 that is replaceably installed. 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 the on / off state of the buck converter 250.

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 current. By using the knob 253, appropriate power can be supplied to various kinds of lamps 300.

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). Each of the resistance terminals is connected to its own resistors, and the resistance terminal is configured to be connected to the output port 270. The designer can adjust the output voltage 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 the set output voltage and current, a measured output voltage and current is provided on one side of the distributor 200, and a distributor input unit 211 is provided below the display unit 210 to replace the knob 253 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 buck converter 250, 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.

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, it becomes convenient to cope with the case where 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 the method of the above-described embodiments, but the embodiments may be modified so that various modifications may be made. All or some of them may be selectively combined.
