According to the invention Pest An overview of the device

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which: FIG. The present invention starts from the basic concept that the attraction efficiency is further enhanced by emitting the attracted light by changing the on / off, intensity, cycle, etc. of the attracted light rather than emitting the attracted light of a constant intensity. Generally, in the case of a light emitting type capturing apparatus having a power supply unit such as SMPS and driven by DC, separate components for performing such a function are required in order to emit while changing the attracted light. On the other hand, the AC driving type LED lighting may have an off time due to its inherent characteristics, and in particular, the LED lighting of the sequential driving type may have an optical output variation depending on the operation range. Accordingly, the present invention proposes a captive device capable of outputting while changing the attracted light without adding additional components by implementing the captive device using the LED lighting of the sequential driving method.

Hereinafter, with reference to Figs. 1 and 2, structural features of the capture device 1000 according to the first embodiment of the present invention will be described in detail.

1 to 3, a trapping apparatus 1000 according to a first embodiment of the present invention includes a housing 100, a front cover 110, a first grill portion 120, a second grill portion 120, The grill portion 122, the first light emitting portion 300, the adhesive sheet 130, the rectifying portion 200, and the first light emission control portion 410.

The housing 100 is formed to have a predetermined space therein and open at its one side. And one side or both sides of the opened one side may be formed in an open shape. That is, as shown in FIG. 2, the housing 100 is formed such that both open sides and both open sides thereof are opened. The housing 100 is formed such that the height of the housing 100 from the bottom surface of the housing 100 becomes lower as the insects flow from both sides toward the center so that the insects flowing into both sides of the housing 100 can not go outside. Further, a plurality of latching portions may be formed on the back surface of the housing 100 so as to be installed on the wall surface. The housing 100 may be formed of a metal or plastic material.

The first grill part 120 is installed at a position opened on one side of the housing 100 and is formed in a mesh shape to provide a passage through which insects flow. So that insects can flow into the housing 100 through the mesh. The size and shape of the mesh of the first grill part 120 can be formed differently depending on the size of the insect to be attracted and the flight style. If necessary, the first grill part 120 may be coated with a photocatalyst for generating carbon dioxide to attract insects.

At this time, the photocatalyst is a material functioning as a photocatalytic medium and may include titanium oxide (TiO ₂ ), silicon oxide (SiO ₂ ), tungsten oxide (WO ₃ ), zirconium oxide (ZnO) Mixture.

The photocatalyst may react with light emitted from the first light emitting unit 300 to generate radicals having strong oxidizing properties. The radicals decompose the organic components around the photocatalyst and generate carbon dioxide. The carbon dioxide is known as a gas capable of attracting insects in a smell and the organic substances in the air around the first grill part 120 are decomposed by the generated radicals to purify the air around the first grill part 120 Can also be performed.

In order to increase the production efficiency of carbon dioxide, an attractant such as lactic acid, amino acid, sodium chloride, uric acid, ammonia or proteolytic substance may be additionally applied to the first grill part 120. These attractants can be applied by a method such as spraying the photocatalyst periodically or non-periodically as needed.

As shown in FIG. 2, the first grill part 120 is installed apart from the first light emitting part 300. So that the path through which the first light emitting part 300 is attracted to the interior of the housing 100 is not obstructed. Also, the first grill part 120 is detachably installed in the housing 100.

The second grill part 122 is installed at a position where the second grill part 122 is opened on the other side of the housing 100. However, unlike the first grill part 120, That is, in the first embodiment, the insect flows into the housing 100 only through the first grill portion 122.

The front cover 110 is installed on the first and second grill parts 120 and 122 so as to cover the opened one side of the housing 100. 1 and 2, when the first and second grill parts 120 and 122 are mounted on the housing 100, the front cover 110 is rotated by the first grill part 120 And the second grill portion 122 to cover the opened one side of the housing 100. [ The front cover 110 is curved toward the inner surface of the housing 100 so that the height of the bottom surface of the housing 100 decreases from the both sides toward the center. Accordingly, insects attracted to the inside of the housing 100 can be caught by the adhesive sheet 130 to be described later after passing along the curved surface (curved surface) of the front cover 110.

The front cover 110 is detachably attached to the housing 100. The user can remove the insects remaining in the interior of the housing 100 through the opened face of the housing 100 by removing the front cover 110, The sheet 130 may be replaced.

The first light emitting unit 300 may emit light to the outside through the first grill unit 120 and may be a light having a wavelength of one of ultraviolet rays, visible rays, and infrared rays because the emitted light is for attracting insects . For example, the first light emitting portion 300 may emit ultraviolet light and may have a wavelength band of about 200 nm to 400 nm.

Here, it is reported that the flies attracting insects are, for example, light of a wavelength of about 340 nm to 575 nm for flies and brownflies, and light of a wavelength of about 366 nm for moths and mosquitoes. It has also been reported that, in the case of other general pests, light with a wavelength of about 340 nm to 380 nm is relatively preferred.

That is, the light emitted from the first light emitting unit 300 may be reflected by the reflection plate 320 and may be emitted to the outside through the first grill unit 120. Accordingly, the light emitted from the first light emitting portion 300 can be radiated over a wide range, and it can be irradiated only within a predetermined range if necessary.

In addition, the first light emitting portion 300 may be covered with a light-transmissible cover at the upper portion in a state where the LED chip or the LED package is arranged. The light-transmissive cover functions to protect the LED chip and the LED package included in the first light emitting portion 300, and may be formed in various shapes as needed. The light-transmissive cover may serve as a lens for diffusing the light emitted from the first light emitting unit 300 or for converging light in a predetermined direction. Accordingly, the light-transmissive cover may include glass, quartz, light-transmitting polymer, or the like.

The first light emission control unit 410 is configured to control the sequential driving of the plurality of LED groups constituting the first light emitting unit 300 according to the voltage level of the input voltage. The first light emission control unit 410 and the circuit characteristics will be described in more detail with reference to FIG. 4C.

3 is a block diagram showing the electrical connection between the components in the capture device according to the first embodiment of the present invention. 4A to 4C are waveform diagrams showing the relationship between the rectified voltage and the LED driving current of the capture device according to the first embodiment of the present invention.

3, the trapping apparatus 1000 according to the first embodiment of the present invention includes a rectifying section 200, a first light emitting section 300, and a first And a light emission control unit 410.

3, the rectifier 200 according to the present invention rectifies the AC voltage (i.e., the input voltage Vac) input from the AC power source to generate the rectified voltage Vrec, Vrec to the first light emitting unit 300 and the first light emitting control unit 410. [ As such a rectifying part 200, one of various known rectifying circuits such as a full-wave rectifying circuit, a half-wave rectifying circuit and the like can be used.

The first light emitting unit 300 may include a plurality of LED groups. The plurality of LED groups included in the first light emitting unit 300 may be divided into a plurality of groups according to the voltage level of the rectified voltage Vrec, Sequentially emitted under the control of the control unit 410, and sequentially turned off. 3 illustrates a first light emitting device 300 including a first LED group 302, a first LED group 304, a first LED group 306, and a first LED group 308, The number of LED groups included in the first light emitting unit 300 and / or the number of LEDs included in each LED group may be variously changed according to need, as will be apparent to those skilled in the art will be. Hereinafter, for convenience of explanation and understanding, the first light emitting unit 300 will be described with reference to an embodiment including four LED groups, but the present invention is not limited thereto. For example, the first light emitting unit 300 may include three LED groups from the first LED group 302 to the first LED group 306, It will be apparent to those skilled in the art that the present invention covers the scope of the present invention.

Further, according to the embodiment, the first 1-1 LED group 302 to the first 1-4 LED group 308 may have different forward voltage levels from each other. For example, when the first 1-1 LED group 302 to the first 1-4 LED group 308 are configured to include different numbers of LED elements, respectively, or when the 1-1 th LED group 302 to the 1- When each of the four LED groups 308 has a different type of serial or parallel or serial or parallel connection relationship, the first to eighth LED groups 302 to the first to fourth LED groups 308 have different forward voltage levels Will be. Of course, all or a part of the 1-1th LED group 302 to the 1-4th LED group 308 may be configured to have the same forward voltage level.

The first light emission control unit 410 according to the present invention determines the voltage level of the rectified voltage Vrec and determines the first to eighth LED groups 302 to the first to fourth LED groups 308 ) In response to the control signal.

In more detail, the first light emission control unit 410 according to the present invention determines the voltage level of the rectified voltage Vrec to be input and, according to the determined voltage level of the rectified voltage Vrec, And controls the sequential driving of the 1-1th LED group 302 to the 1-4th LED group 308 by controlling the constant current switches CS1-1 to 1-4 constant current switches CS1-4. More specifically, in the section (the first-stage operation section) in which the voltage level of the rectified voltage Vrec is equal to or higher than the first-first forward voltage level Vf1-1 and less than the second-second forward voltage level Vf1-2, The first emission control unit 410 turns on the 1-1 constant current switch CS1-1 to connect the 1-1 current path P1-1 so that only the 1-1 second LED group 302 emits light Respectively. Similarly, in a section where the voltage level of the rectified voltage Vrec is equal to or higher than the 1-2 forward voltage level (Vf1-2) and lower than the 1-3 forward voltage level (Vf1-3) The first light emission control unit 410 turns on the first and second constant current switches CS1-2 to connect the first and second current paths P1-2 and thereby, -2 LED group 304 is controlled to emit light. In the section (the operation section of the first to third stages) in which the voltage level of the rectified voltage Vrec is equal to or higher than the first to third forward voltage levels Vf1-3 and lower than the first to fourth forward voltage levels Vf1 to 4 1 light emitting control unit 410 turns on the first to third constant current switches CS1-3 to connect the first to third current paths P1-3, 3 LED group 306 to emit light. Lastly, when the first emission control unit 410 receives the first to fourth constant current switches SW1 to SW4 in the period (the operation period of the first to fourth steps) in which the voltage level of the rectified voltage Vrec is equal to or greater than the first to fourth forward voltage levels Vf1 to 4, The first to fourth LED groups 302 to the first to fourth LED groups 308 are controlled to emit light by turning on the first to fourth current paths CS1 to CS4 to connect the first to fourth current paths P1 to P4.

In addition, the first light emission control part 410 according to the present invention controls the first constant current switches CS1-1 through the first constant current switches CS1-4 so that the LED driving current is set to a predetermined value The constant current control may be performed.

First, the 1-1 constant current switches CS1-1 through 1-4-4 according to the present invention are turned on or off according to the control of the first light emission control unit 410 , And constant current control of the LED driving current ILED flowing through each of the constant current switches. The first 1-1 constant current switches CS1-1 through 1-4 may be implemented using various known techniques. For example, each of the 1-1 constant current switches (CS1-1) to the 1-4 constant current switches (CS1-4) according to the present invention may include a sensing resistor for detecting a current, a reference current value, And a switching device configured to control the connection of the path according to the output of the differential amplifier and to control the LED driving current flowing through the path with a constant current when the path is connected. Further, the switching element constituting the constant current switch may be implemented as one of various known electronic switching elements such as a bipolar junction transistor (BJT), a field effect transistor (FET), and the like.

In one embodiment, the first light emission control section 410 sets an LED drive current value for each operation section on the basis of the resistance value of an external LED drive current setting resistor, and based on the LED drive current value, And may be configured to perform a function of controlling with a constant current. That is, in this embodiment, only one LED driving current setting resistor (not shown) is provided so that the reference LED driving current value is set as a reference, and the value of the LED driving current per operation section is set as a reference As a ratio of the LED drive current value. In order to improve the power factor and to improve the total harmonic distortion (THD), the first light emission control unit 410 (FIG. 4) according to the present invention is arranged to approximate the waveform of the rectified voltage Vrec to which the LED drive current ILED is input May be configured to control the LED driving current ILED constantly so that the value of the LED driving current ILED sequentially increases from the first-stage operation section to the first-fourth operation section. That is, the first LED driving current ILED1-1, the first LED driving current ILED1-2, the first LED driving current ILED1-3, the first LED driving current ILED1-3, The first light emission control unit 410 may be configured to control the LED drive current for each operation period so that the relationship of 'ILED1-4' is established. This relationship is shown in FIG. 4A. That is, as shown in Fig. 4A, the first to eighth LED driving currents ILED1-1 to ILED1-4 are sequentially applied so as to approximate the waveform of the input rectified voltage Vrec So that the current value increases. In this embodiment, since the LED driving current varies according to the operation period, an effect of changing the light output of the first light emitting unit 300 for each operation period can be expected. That is, the light output of the first light emitting unit 300 sequentially increases from the first operation period to the first operation period, and sequentially increases from the first operation period to the first operation period, The light output of the light emitting portion 300 is reduced. In particular, since the present invention adopts the sequential driving method, the number of LEDs to emit light per operation section changes, so that the optical output deviation per operation section can be larger.

In another embodiment, the first light emission control unit 410 sets an LED drive current value for each operation section based on the resistance value of the plurality of LED drive current setting resistors, and based on the LED drive current value, And may be configured to perform a function of controlling with a constant current. The LED drive current for each operation section can be set using a resistor for setting the 1-1 LED drive current (not shown) to a resistor for setting the 1-4 LED drive current (not shown). The 1-1 LED driving current setting resistor is a resistor for setting the 1-1 LED driving current (ILED1-1) value during the 1-1th operation period, and the 1-2 LED driving current setting resistance Is a resistance for setting the value of the 1-2 LED driving current ILED1-2 during the first and second operation periods, And the resistor for setting the 1-4 LED driving current is a resistor for setting the 1-4 LED driving current ILED1-3 during the 1-4th operation period, 4) A resistor for setting the value. In this embodiment, the first light emission control part 410 according to the present invention uses the 1-1 LED driving current setting resistor to the 1-4 LED driving current setting resistor, The drive currents ILED1-1 to the LED drive currents ILED1 to ILD4 of the first to fourth operation periods can be set to desired values. FIG. 4C is a diagram showing the relationship between the first to third LED driving currents ILED1-3 and the first to fourth LED driving currents LED driving current ILED1-4> LED driving current ILED1-1> first LED driving current ILED1-2 '. Similarly, in this embodiment, since the number of LEDs to emit light and the value of the LED driving current vary according to the operation interval, the effect of changing the light output of the first light emitting unit 300 for each operation interval can be expected.

The first light emission control unit 410 according to the present invention may be configured to perform dimming control by controlling the LED driving current ILED flowing through the first light emitting unit 300 according to the selected dimming level. Generally, this dimming control is performed by the first light emission control section 410 controlling the magnitude of the LED drive current ILED based on the dimming level, based on the characteristic that the light output of the LED is proportional to the LED drive current. For example, with an 80% dimming level, dimming control according to the 80% dimming level can be performed by controlling the LED driving current (ILED) to 80% of the LED driving current (ILED) value at the 100% dimming level . Figure 4b shows a dimming controlled waveform diagram of the capture device as described above with reference to Figure 4a.
