Description

[0001] The present invention relates to a light guiding plate module for an LED lighting device,

The present invention relates to an LED flat panel illuminating device having an integrated reflective sheet, and more particularly, to a reflective sheet that does not require a separate metal shield plate by coating a metal reflective layer, thereby reducing the overall number of parts of the lighting device, The pollution level around the lighting apparatus is checked by adding the means for checking the pollution source and the pollution level is notified to the outside when the pollution degree is out of the standard range, And more particularly, to an LED flat panel illumination device having an integral reflective sheet.

Today, a variety of lighting fixtures are being used to provide light or illuminate objects in night or dark rooms. Especially, the lighting lamp that uses the light emitting diode (light emitting diode) as the light source has a lower power consumption than the incandescent lamp or the fluorescent lamp and saves the energy. In addition to the conventional light sources, the solid type point light source is robust, has a long life, In terms of characteristics, it is advantageous in terms of maintenance and the like.

However, a light-emitting diode in the form of a simple combination of light-emitting diodes emits optically clear monochromatic light, which causes uncomfortable glare and eye fatigue to the user, so that it can be used as indirect lighting for direct lighting or indoors It is important that an appropriate lens or light guide plate is coupled.

In recent years, by appropriately maintaining the distance between the light emitting diode and the light guide plate for diffusing the light, the light of the point light source generated from the light emitting diode is converted into the light of the planar light source (light source having the light- LED flat panel lamps have been developed in various forms, replacing existing fluorescent lamps.

Such LED flat-panel luminaire can be divided into edge-lighting type and direct-lighting type depending on the manner in which the light emitting diode is disposed and the direction in which the light is directly emitted and emitted.

In the latter case, it is advantageous to make the product slim due to its relatively thin thickness, but it has disadvantages of reduced luminance and weight due to the light guide plate. In the latter case, when the thickness of the product is reduced, the LED dot (light emitting diode) There is a limit to the slimness because a separate space is required for using the SMPS.

In recent years, there has been developed a product in which the power supply circuit is disposed on the same PCB as the light emitting diode (LED), and the thickness is reduced and the installation process is simplified. However, due to the short life of the power supply circuit, The long-life characteristics are maintained, and thin-walled side-emitting type products are in the spotlight.

1 and 2, a lighting apparatus 100 (hereinafter, referred to as an illuminator) using a light guide plate according to an embodiment of the present invention includes a frame 110 that is a basic frame of a lighting apparatus. A light guide plate 120 is disposed inside the frame 110 and an LED module 130 is disposed along a side surface of the light guide plate 120. A reflective sheet 140 is disposed on the upper surface of the light guide plate 120 surrounded by the LED module 130 and a diffusion plate 150 is disposed on the lower surface of the light guide plate 120 Respectively. The cover 160 is coupled to the opened upper surface of the frame 110.

The reflective sheet 140 applied to the present invention comprises a base sheet layer 142 and a metal reflective layer 144.

First, the base sheet layer 142 made of a white opaque synthetic resin imparts basic reflective and hiding properties to the reflective sheet. "White opaque synthetic resin" of the base material sheet layer 142 means a synthetic resin having a white color due to mixing of white pigment and dispersion of fine bubbles.

Specific examples of the synthetic resin that can be used for the substrate sheet layer 142 include polyethylene terephthalate (PET), polyethylene naphthalate, acrylic resin, polycarbonate, polystyrene, polyolefin, cellulose acetate, polyvinyl chloride and the like, It is not. Of these, PET having excellent heat resistance is preferable.

The thickness of the base sheet layer 142 is preferably, for example, 100 占 퐉 to 300 占 퐉, but is not particularly limited. If the thickness of the base sheet layer 142 is less than 100 m, the reflectance of the base sheet layer 142 itself is insufficient and the brightness is lowered. If the thickness of the base sheet layer 142 exceeds 300 占 퐉, rolled curl tends to occur in the coating process, the storage process, and the sheet process. Specific examples of the white pigment include, but are not limited to, titanium oxide, silicon oxide, zinc oxide, lead carbonate, barium sulfate, calcium carbonate, and aluminum oxide. Among them, titanium oxide having a large effect of improving the hiding ability is preferable.

The average particle diameter of the white pigment is preferably from 0.1 to 50 mu m, more preferably from 0.1 to 5 mu m. If the average particle diameter of the white pigment is less than 0.1 占 퐉, there is a concern that sufficient reflective and hiding properties can not be imparted to the reflective sheet 10, and if the average particle diameter of the white pigment exceeds 50 占 퐉, There is a fear that this may become uneven.

In addition, since the metal reflection layer 144 has a large light reflection coefficient, the reflection sheet having the metal reflection layer 144 has a greatly improved light reflectance. Therefore, when the reflective sheet according to this embodiment is used in the backlight unit, the brightness of light emitted from the light guide plate is excellent. The metal reflective layer 144 may be formed of any metal having a property of reflecting light rays. Specific examples of such metals include, but are not limited to, copper, silver, aluminum, tin, gold, brass, bronze, stainless steel and the like. Among them, silver (Ag) is preferable because it is excellent in properties of mirror-reflecting without absorbing light. The method of forming the metal reflection layer 14 is not particularly limited, and a known method of forming a metal layer such as a deposition method and a sputtering method can be used without any limitation.

The thickness of the metal reflection layer 144 is not particularly limited, but is 50 to 2000 占 preferably 100 to 1500 占 and more preferably 500 to 1000 占. When the thickness of the metal reflection layer 144 is less than 50 angstroms, the effect of improving the reflectance is small and many voids are generated on the surface of the metal reflection layer 144, so that it is difficult to form a uniform thin film. If the thickness is more than 2000 ANGSTROM, the deposition or sputtering rate is slow, so that the fabrication cost increases and the physical property can not be improved as compared with the case where the thickness is increased.

In addition, the frame 110, the LED module 130, and the light guide plate 120 are the main components of the present invention. The frame 110 according to the present invention includes upper, lower, left and right sides And the LED module 130 and the light guide plate 120 are installed in the interior of the LED module 130. The LED module 130 and the light guide plate 120 are installed on the right and left sides, That is, when the light from the LED module 130 is output, the light is projected downward through the light guide plate 120 to provide uniform light.

In the meantime, according to the present invention, a dust measuring means is installed at one end of a frame 110, dust is detected through the dust measuring means 2000, and when dust above a reference level is detected, the dust is outputted through an alarm signal, Thereby inducing the user to be informed that the dust is polluted more than the reference level, thereby preventing electrical shorting of the lighting device caused by excessive dust, and inducing ventilation to induce living in a pleasant environment. That is, a dust measuring means is provided at one end of the frame in order to determine whether dust is present on a reference or more, and the amount of dust around the lighting apparatus is measured by the dust measuring means to inform the outside of the dust amount .

The data measured by the dust measuring unit 2000 is transmitted to the dust measuring control unit 3000 and the dust measuring control unit 3000 displays the data measured by the dust measuring unit on the display 4000.

The dust measuring means 2000 of the present invention includes an infrared transmitting means (A) for emitting infrared rays, a receiving means for receiving the light emitted from the infrared transmitting means and positioned to face the infrared transmitting means, (D) for controlling the input voltage of the infrared ray transmitting means (A) to increase when the output voltage of the infrared ray receiving means (B) is smaller than a predetermined value, an infrared ray receiving means (C).

The infrared transmitting unit A receives the infrared transmitting control signal from the dust measuring control unit C, determines the infrared transmitting amount, and outputs the changed infrared transmitting amount.

That is, when the result of the infrared ray receiving means B is transmitted to the dust measurement control section C, the dust measurement control section C predicts the dust generation amount based on the data of the infrared ray receiving means B, And outputs a control signal to the infrared ray transmitting means (A) to adjust the infrared ray transmission amount to induce the output.

That is, the light amount data outputted from the infrared ray receiving means is read by the dust measurement control unit, and the light amount of the infrared light emitting means is automatically controlled based on the read light amount data, so that the sensitivity adjustment is automatically maintained constant. So that the measurement can be performed while maintaining the sensitivity state.

In other words, the dust measurement control section C determines that the degree of contamination is high when the amount of received light of the infrared ray receiving means B is low, and outputs a control signal to increase the light amount of the infrared ray transmitting means A If the amount of light received by the infrared ray receiving means C is too high, a contamination-free state or a precise measurement becomes difficult. Therefore, a control signal is outputted so as to lower the light amount of the infrared ray transmitting means A That is, it is necessary to keep the amount of infrared transmission light in an appropriate state. The infrared ray amount measured through the infrared ray receiving means is accurate and the dust amount can be more precisely predicted. Therefore, the dust amount data measured by the dust measurement control unit of the present invention can output the dust measurement result with high reliability.

In the present invention, when the dust measurement control unit C outputs a control signal in order to facilitate the change of the light amount of the infrared ray transmission unit, the transmission control unit 1 recognizes the control signal and drives the infrared ray transmitter conversion unit to perform the most appropriate infrared ray transmission .

The infrared transmitter converting means 2 includes a plurality of moving electromagnets 2a, 2b and 2c which are wound around the actuator 3 and are mounted with a predetermined distance therebetween and fixed to a position adjacent to the moving electromagnets 2a, 2b and 2c And a plurality of stationary electromagnets 2d, 2e, 2f to be installed,

When a signal from the transmission control section 1 is applied, current flows through the floating electromagnets 2a, 2b, 2c and the fixed electromagnets 2d, 2e, 2f to form magnetic poles , 2c and the fixed electromagnets 2d, 2e, 2f to generate the repulsive force and attracting force to drive the actuator 3.

The actuator 3 is provided with a plurality of concave lens groups for limiting the infrared ray output by the flow of the infrared transmitter converting means 2.

The infrared transmitter flow means 4 for performing this operation includes an infrared ray transmission element 4a for outputting infrared rays to the outside in proximity to the concave lens group 5 formed on the outer peripheral edge of one side of the actuator 3 in the longitudinal direction, A moving bar 4b for moving the infrared ray transmitting element 4a and a solenoid 4c for moving the infrared ray transmitting element to the left and right by moving the moving bar.

In the configuration described above, when the actuator 3 is moved, the infrared ray transmitting element 4a flows to the left and right due to application of power to the solenoid 4c.

A plurality of the infrared transmitting lens groups 5 are arranged on the working rods and are designed so that the degree of output of the infrared light is varied according to the depression angle of the center portion. The infrared ray of different intensity can be outputted.

The second concave lens 5c disposed above the third concave lens 5c when the infrared light is to be output with a small amount of light, and the second concave lens 5c provided above the third concave lens 5c, And outputs light through the first concave lens 5a provided above the second concave lens 5b when the infrared ray is to be output by further reducing the amount of infrared light. When the infrared ray is to be outputted with higher light intensity, light is output through the fourth concave lens 5d provided below the third concave lens 5c. When the infrared ray is to be outputted with higher intensity, And outputs the light through a fifth concave lens 5e provided below the second concave lens 5d.

The concave lens group is designed to have a different degree of output of infrared light depending on the depression angle of the central portion, and a lens having different degrees of depression can be selected by the movement of the infrared transmitter conversion means to output infrared light of different intensity The third concave lens 5c is basically provided at the center of the working rod and forms a depression angle of 25 degrees.

The second concave lens 5b is used for outputting a slightly reduced amount of infrared light and is provided above the third concave lens 5c to form a depression angle of 15 degrees.

The first concave lens 5a is used when it is required to further reduce the amount of infrared light and is disposed above the second concave lens 5b and forms a depression angle of 5 degrees.

The fourth concave lens 5d is used when it is necessary to output the infrared ray with a higher light output, and is provided at the lower side of the third concave lens 5c and forms a depression angle of 35 degrees.

The fifth concave lens 5e is used when it is necessary to output the infrared ray with a higher intensity, and is provided below the fourth concave lens 5d and forms a concave angle of 45 degrees.

When the infrared light needs to be increased, the actuator 3 is raised and the actuator 3 is lowered when the infrared light needs to be reduced.

The first fixing electromagnet 2d, the first moving electromagnet 2a, the second fixing electromagnet 2e, the second floating electromagnet 2b, and the second fixing electromagnet 2b are controlled by the transmission control unit 1, (2f) - the third floating electromagnet (2c) is given a repulsive force signal and the second fixing electromagnet (2e) - the first floating electromagnet (2a), the third fixing exclusive magnet When the attracting force is applied to the electromagnet 2b, the actuator 3 is lowered to place the first mounting electromagnet 2a in the position of the second fixing electromagnet 2e and the second mounting electromagnet 2a in the position of the third fixing electromagnet 2f. The mounting electromagnet 2b is positioned. Accordingly, when the operating rod is lowered by one step, the infrared ray transmission element 4a comes close to the second concave lens 5b and outputs infrared light through the second concave lens 5b.

The third switching transistor Q3 switches the circuit according to a switching signal input to the base.

The fourth switching transistor Q4 is provided on the other side of the output terminal of the power supply unit to switch the power supply unit output from the power supply unit.

The relay switch RL1 is coupled to the output terminal of the fourth switching transistor and generates a magnetic force when the fourth switching transistor is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The second communication signal output power switch sw2 serves to induce a communication signal to be output through the communication signal output unit 1150 by supplying power to the communication signal output control unit 1140 while the iron wire is pulled by the relay switch do.

The communication controller 1120 switches the third switching transistor and the fourth switching transistor to switch the relay switch so that the first circuit connection switch and the second communication signal output power switch are switched, A first circuit connection switch configured to switch the first switching transistor and the second switching transistor while turning off the switching transistor and the fourth switching transistor and to turn off the relay switch and simultaneously to be interlocked with the first switching transistor and the second switching transistor And maintains the communication state by continuing the switching state of the second communication signal output power switch.

In addition, the present invention is characterized in that it comprises a circuit board 1131 for operation, a wire piece 1132 for connection to a power supply for operating a communication signal control unit, a first resilient holding means 1133, a second resilient holding means 1134, (1133a), and a manual operation switch (1135).

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 and relays the power delivered from the second switching transistor to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first elastic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 so that the first circuit connection switch sw1 and the circuit operation wire 1131 are always kept in the off state when the relay switch is not operated .

The second elastic holding means 1134 is installed on the upper portion of the first circuit connecting switch sw1 and is spaced apart from the first elastic holding means by a predetermined distance. When the relay switch is operated, the circuit breaker 1131 is pulled to be coupled with the first resilient holding means 1133 while the first resilient holding means is overlapped, and at the same time, the first circuit connecting switch sw1 is switched So that even if the operation of the relay switch is stopped, the state of attaching the circuit breaker 1131 continues to maintain the power supply state through the first switching transistor and the second switching transistor. At this time, when the circuit breaker 1131 is operated by the operation of the relay switch, the communication piece 1132 is automatically operated to output the communication signal to the outside.

The gap maintaining means 1133a guides the second elastic holding means 1134 and the first elastic holding means 1133 to be engaged with each other while maintaining a constant gap without being directly coupled to each other when the first elastic holding means 1134 and the first elastic holding means 1133 are engaged, 1133 and the second resilient holding means 1134 can be more smoothly separated from each other by the action of the gap maintaining means at the time of disassembly. If the gap maintaining means is not present, the first elastic holding means 1133 and the second elastic holding means 1134 are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, the first elastic holding means 1133 and the second elastic holding means 1134 can be easily separated by further providing the gap holding means 1133a.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a communication signal output control unit. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, a power is applied to the third switching transistor and the fourth switching transistor to operate the relay switch RL1. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch sw1 is operated, the control unit interrupts the operation of the third switching transistor and the fourth switching transistor to cut off the operation of the relay switch, and simultaneously operates the first switching transistor and the second switching transistor.

On the other hand, if the operator turns off the first circuit connecting switch and the communication signal output power switch in the middle of outputting the communication signal, the control unit recognizes this, and then the third switching transistor and the fourth switching transistor are operated, It is possible to keep the closed circuit while moving the iron piece and at the same time return the power outputted to the communication signal control part 1140 to continuously operate the communication signal output part 1150.

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when a switching signal is applied to the third switching transistor, the fourth switching transistor, the first switching transistor, and the second switching transistor in the control unit, the communication signal is automatically output by returning the power source again, It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output a communication signal, the control unit no longer applies a power supply signal to the first switching transistor, the second switching transistor, the third switching transistor, and the fourth switching transistor. ) Can be manually operated by a user to interrupt the communication signal.
