1 is a perspective view schematically showing a ceiling structure of a clean room in which a fan filter unit is installed.

As shown in Fig. 1, the ceiling structure of the clean room is generally aluminum mold bar (Mould bar) 10 is installed in a lattice structure, the mold bar 10 is suspended by bolts (20). It includes a structure suspended from the frame 30.

And, at the top of the mold bar 10, a fan filter unit 100 that maintains the cleanliness inside the clean room is installed at regular intervals, and a blind panel 50 is installed between them.

However, as shown in FIG. 3, in the embodiment of the present invention, the LED module is basically located inside the clean room filter assembly through the through hole of the LED integrated casing assembly. That is, the LED module is integrated with the LED-integrated casing assembly and the clean room filter instead of separately installed at the bottom of the mold bar, so that a separate lighting installation structure is not required for the mold bar. Of course, it is natural that the LED-integrated clean room fan filter system 100 is also supported by a mold bar.

4A to 4C are perspective views schematically showing an LED-integrated clean room fan filter system 100 according to an embodiment of the present invention.

4A to 4C, the LED-integrated clean room fan filter system 100 according to an embodiment of the present invention includes a casing assembly 110, an LED socket 120, an LED module 130, and a filter assembly ( 140) may be included. Here, as described above, the LED-integrated clean room fan filter system 100 may be mounted inside a substantially rectangular frame formed by the mold bar 10.

The casing assembly 110 has a generally hexahedral shape, the upper and lower parts are generally open, the fan 111 is mounted inside, and the outer side with the filter assembly 140 is mounted on the mold bar 10 in the form of a square frame. Can be. Here, the casing assembly 110 further includes a motor (not shown) installed therein, and the fan 111 may be coupled to the motor to rotate the fan 111. In addition, the casing assembly 110 is provided with an over case 112 on which a fan 111 (ie, a motor and a fan) is installed on the upper surface, and the over case 112 controls the fan 111, and the fan 111 ) And the LED module 130, and a fan control unit 113 that transmits the alarm state of the fan 111 may be further installed.

The LED socket 120 may be installed on opposite sides of the casing assembly 110, respectively. It is natural that the LED socket 120 is also located inside the frame formed by the mold bar 10 described above. The length of the LED socket 120 may be equal to or less than the length of the side of the casing assembly 110 described above.

A pair of LED sockets 120 installed on both sides of the casing assembly 110 includes a case 121, a connector 122 (see FIGS. 5C, 5D and 6B, 6C) and a cover 126, respectively. I can. The case 121 is directly coupled to both sides of the casing assembly 110, and may have a substantially rectangular parallelepiped shape with open upper and lower portions. Accordingly, the LED module 130 may be coupled/separated in a vertical direction (up-down direction) and in a sliding manner in the case 121 of the rectangular parallelepiped shape. Connector 122 is installed inside the case 121, which may be installed one by one at both ends (front, rear) of the case 121. The connector 122 will be described again below, but it can fix the LED module 130 and supply power to the LED module 130. The cover 126 may be coupled to the upper portion of the case 121 through a hinge, which covers the upper portion of the case 121 after the LED module 130 is coupled to the case 121 to prevent particles from the case 121 It prevents descending into the clean room through the gap between the LED modules 130 and also prevents light leakage caused by the LED modules 130.

The LED modules 130 may be respectively coupled to the LED socket 120 to provide lighting in the clean room. The LED module 130 may include a power supply block 131 and an LED lamp 135. The power supply block 131 has a substantially thin rectangular parallelepiped shape, which can be coupled to the above-described LED socket 120 by sliding in a vertical direction (eg, from top to bottom). In addition, the LED lamp 135 may have a generally fluorescent lamp shape, which is electrically connected to the lower end of the power supply block 131 to receive power from the power supply block 131.

The filter assembly 140 may include a body 141 and a filter 143. The body 141 may have through holes 142 formed at positions corresponding to the LED socket 120 and the LED module 130, respectively. The through hole 142 may have a substantially rectangular shape so that the LED lamp 135 can pass. The filter 143 may be a HEPA filter or a wool filter, which is coupled to the inner side of the body 141 to block the lower portion of the casing assembly 110 described above. Accordingly, the LED lamp 135 of the LED module 130 is exposed, protruded or embedded in a downward direction through the through hole 142 of the body 141 described above, thereby providing illumination inside the clean room.

In this way, the LED module 130 is not installed on the mold bar 10 as in the prior art, but is formed integrally with the clean room filter system 100, thereby reducing the installation work of the LED-integrated clean room fan filter system 100. It is simple and the construction time can also be greatly shortened. In addition, the excess power of the LED-integrated clean room fan filter system 100 is used as the power source of the LED module 130, so that the wiring structure of the power line is simplified and power can be efficiently used.

In addition, since the LED module 130 can be coupled and separated from the clean room filter system 100 in a sliding manner, it is easy to combine and replace the LED module 130. Moreover, the cost of clean room construction may be reduced by the LED-integrated clean room fan filter system 100.

5A, 5B, 5C, 5D, 5E, and 5F are perspective views showing the LED module 130 and the connector 122 of the LED-integrated clean room fan filter system 100 according to an embodiment of the present invention. to be. (I will add a picture data of the connector type)

In this way, the power supply cable 225 of the connector 220 is directly inserted and coupled to the power terminal cable of the power supply block 131, so that the coupling force between the power lines may be further improved. For example, the coupling force between the power lines may be loosened due to long-term micro-vibration of the LED-integrated clean room fan filter system 100. As described above, due to the direct coupling between the power lines, this phenomenon is prevented and accordingly The probability of particle generation can also be reduced. Although not shown in the drawings, the power supply block 131 may be provided with a power terminal cable that is directly inserted and coupled to the power supply cable 225 instead of the exposed power terminal.

The alarm display unit 151 may receive an alarm state of the fan control unit 113 and transmit an alarm signal to the LED control unit 152. The LED control unit 152 may receive an alarm signal from the alarm display unit 151 and output an LED control signal to the LED module 130. Here, the LED control unit 152 supplies power to the LED module 130 in normal (normal state of the fan 111), but in an alarm state (abnormal state of the fan 111), the LED module installed opposite to both sides It can be controlled to turn on and off by alternately supplying power to 130. Of course, in addition to these methods, the LED control unit 152 may notify the user of the abnormal state of the fan 111 in various ways. For example, the LED module 130 may emit light periodically or aperiodically, or the LED module ( By lowering the illuminance of 130) or by allowing the LED module 130 to emit light in a specific color (eg, red), the current fan 111 may be informed to the user that the fan 111 is in an abnormal state.
