1 to 7 , the work light 100 for blocking blue light according to an embodiment of the present invention includes a lighting unit 110 , a support unit 120 , and an attachment unit 130 .

The lighting unit 110 is maintained in a vacuum state inside, a plurality of LEDs 111 are formed. In this case, the LEDs 111 are formed in a preset arrangement structure, and the number of the LEDs 111 may be changed by a user setting. The lighting unit 110 may be implemented in a circular shape or a rectangular shape. The illumination generated from the LED 111 is output by blocking the blue light. In this case, blue light may be reduced or blocked by the diffusion plate 114 or the blocking film 116 to be described later. Accordingly, the user can reduce eye fatigue during work.

The lighting unit 110 may be formed in a structure that can be rotated by the bracket 112 . For example, the bracket 112 is formed in a '┗┛' shape structure, and the lighting unit 110 is connected to the bracket 112 and rotates. The bracket 112 serves to connect the lighting unit 110 and the support unit 120 . However, the present invention is not necessarily limited thereto, and it is also possible to connect the lighting unit 110 to the support unit 120 in the absence of the bracket 112 .

In addition, the lighting unit 110 may have a heat sink 113 formed therein to discharge heat generated from the LED 111 to the outside. For example, the heat sink 113 may be formed in a wave shape with a curved cross-section. This has the advantage of being able to widen the heat dissipation area compared to the straight cross-section. At least one heat sink 113 may be formed in the lighting unit 110 . The heat dissipation plate 113 may be formed such that a plurality of micro-channels, ventilating portions 113-2, are formed to discharge heated air to the outside. Accordingly, heat generated from the LED 111 may be rapidly dissipated.

More specifically, the heat sink 113 includes a contact portion 113 - 1 , a ventilation portion 113 - 2 , a heat sink 113 - 3 , and a locking portion 113 - 4 . The contact portion 113 - 1 serves to absorb heat by contacting one surface of the LED 111 . In this case, the contact portion 113 - 1 may be formed of an aluminum material, but is not limited thereto. The ventilation part 113-2 is formed of a microtubule, and a plurality of the vent parts 113-1 are formed on one side of the contact part 113-1. The ventilation part 113-2 serves to discharge the heat to the outside while moving the heat transferred from the contact part 113-1 up and down.

In addition, the heat dissipation fins 113-3 are formed on one side of the ventilation unit 113-2 to widen a contact surface with air to discharge heat. This serves to more rapidly dissipate the heat transferred to the vent 113 - 2 . The locking part 113-4 has a cross-section formed in a 'L' shape and is coupled to the locking groove 115-4 of the frame 115 to be described later in a sliding manner. This serves to fix and support the heat sink 113 to the frame 115 .

In addition, the lighting unit 110 may have a diffusion plate 114 formed therein to block blue light output from the LED 111 . For example, the diffusion plate 114 may be manufactured by applying a pigment capable of absorbing blue light. For example, the diffusion plate 114 may be formed by mixing a blue light emitter made of a compound of thiophene and benzene to disperse and diffuse blue light in a region of 380 nm to 500 nm in a monomer. Accordingly, the blue light blocking rate can be further increased, and glare, eye fatigue, eye disease, and the like can be prevented.

In addition, a first reflective groove 114 - 1 may be formed on one surface of the diffusion plate 114 , and a second reflective groove 114 - 2 may be formed on the other surface of the diffusion plate 114 . The first reflective groove 114-1 and the second reflective groove 114-2 are formed on the surface in the form of a dimple of a kind of golf ball. The first reflective grooves 114-1 and the second reflective grooves 114-2 serve to eliminate gradation that occurs as the lights irradiated from the plurality of LEDs 111 overlap. In this case, the size of the first reflective groove 114-1 may be larger than that of the second reflective groove 114-2. The light irradiated from the LED 111 is dispersed and uniformly illuminated while sequentially passing through the first reflective groove 114-1 and the second reflective groove 114-2, thereby minimizing the overlapping phenomenon depending on the object. have.

In addition, the lighting unit 110 may illuminate the light by photometric method by the frame 115 . A diffusion groove 115 - 1 , a film groove 115 - 2 , an illumination groove 115 - 3 and a locking groove 115 - 4 may be formed in the frame 115 . The diffusion groove 115-1 is formed in a 'c'-shaped cross-section with one side open. The diffusion groove 115 - 1 serves to fix and support the diffusion plate 114 and the light guide plate 117 when they are inserted. The film groove 115 - 2 is a groove into which the blocking film 116 is inserted into the side of the frame 115 in a sliding manner. The blocking film 116 is a film for blocking blue light. Accordingly, it is possible to increase the blue light blocking effect by using the blocking film 116 in addition to the diffusion plate 114 .

The lighting groove 115 - 3 is a groove formed so that the LED 111 is coupled in a sliding manner from the side of the frame 115 . The lighting groove 115-3 serves to adjust the spacing so that the blocking film 116 and the LED 111 are spaced apart from each other at a preset interval. This is to prevent the blocking film 116 from being deteriorated by the heat of the LED 111 . The locking groove 115-4 is a groove to which the locking part 113-4 of the heat sink 113 is fixedly supported by being coupled in a sliding manner. The locking groove 115 - 4 serves to fix the entire heat sink 113 to the frame 115 . Accordingly, while dissipating heat through contact between the LED 111 and the heat sink 113 , it is possible to prevent the heat sink 113 from being separated from the frame 115 by an external force. In addition, it is easy to assemble and disassemble because it is connected in a boltless way.

The support part 120 is formed with a predetermined length, one side is connected to the lighting part 110 to support it, and the other side is connected to the attachment part 130 to be described later and supported from the bottom surface. It is preferable that the support part 120 is heat-treated on the outer surface of the metal material. In this case, it is also possible to vary the degree of bending of the support part 120 by different heat treatment for each section. The support part 120 is formed to be bent at various angles by an external force. A wire electrically connected to the lighting unit 110 is accommodated inside the support unit 120 .

In addition, connection caps 121 may be formed on both sides of the support part 120 . The connection cap 121 connects the lighting unit 110 or the attachment unit 130 and serves to rotate with each other. In this case, at least one O-ring 122 (O-ring) is formed inside the connection cap 121 to enable waterproofing. In addition, the O-ring 122 minimizes friction between the inside of the connection cap 121 and the lighting unit 110 or the attachment unit 130 to enable rotation. Accordingly, the support part 120 is rotatably connected to the lighting part 110 or the attachment part 130 so that the operator can use it at various angles when using it, and it is possible to reduce the inflow of moisture into the lighting part 110 .

The attachment part 130 is connected to the support part 120 , and a magnetic body 131 is formed on the bottom surface. The attachment part 130 is attached and fixed to the attachment surface 10 made of an iron plate to be fixed by attaching the blue light blocking work light 100 . In this case, the magnetic body 131 may be formed by being divided into 4 poles or 6 poles, but is not limited thereto. Since the magnetic material 131 is formed by being polarized into a plurality of N and S poles, it is possible to prevent the blue light blocking work light 100 from sliding or detaching from the attachment surface 10 by the weight of the lighting unit 110 , etc. .

In addition, the attachment part 130 may be configured using an electromagnet. In this case, the attachment part 130 is magnetized when a current flows to generate a magnetic force, and is not magnetized when the current is cut off. For example, when the attachment part 130 is attached to the attachment surface 10 , a magnetic force is generated by flowing a current, and when stored, the magnetic force is cut off to release the magnetic force, so that it can be separated from the attachment surface 10 . In this case, when the power of the lighting unit 110 is supplied, the attachment unit 130 automatically generates a magnetic force by the flow of current, and when the power of the lighting unit 110 is cut off, the current is cut off so that the magnetic force of the attachment unit 130 is reduced. It comes off and can be easily removed.

8 is an exemplary view for explaining that the conversion magnet is installed in the attachment part of the blue light blocking work light according to FIG. 1, and FIG. 9 is an exemplary view for explaining the change in magnetic force of the conversion magnet of FIG.

1 to 9 , the conversion magnet 132 may be installed in the attachment part 130 . The conversion magnet 132 includes a first magnet 132-1, a second magnet 132-2, a first housing 132-3, a second housing 132-4, and a disk 132-5. do. The first magnet 132-1 is a cylindrical magnet in which the N pole and the S pole are formed in half. One side of the first magnet 132-1 is in contact with the attachment surface 10 by a magnetic force. The second magnet 132-2 is a cylindrical magnet in which the N pole and the S pole are formed in half. A magnet groove 132-21 is formed on one side of the second magnet 132-2. The magnet grooves 132-21 are configured to rotate the second magnet 132-2 by external force. The first magnet 132-1 and the second magnet 132-2 are stacked on each other in the same manner as a millstone.

The first housing 132 - 3 is formed of a ferromagnetic pole. The second housing 132-4 is formed of a ferromagnetic pole, and is coupled to the first housing 132-3 to form a cylindrical shape. The first housing 132-3 and the second housing 132-4 are formed in a curved shape, and are formed of a ferromagnetic material having a low magnetic resistance. The first magnet 132-1 and the second magnet 132-2 are accommodated in the first housing 132-3 and the second housing 132-4. In this case, the first magnet 132-1 is fixed in the first housing 132-3 and the second housing 132-4, and the second magnet 132-2 is rotatably formed. The strength of the magnetic field by the first magnet 132-1 and the second magnet 132-2 varies according to the thickness of the first housing 132-3 and the second housing 132-4.

The disk 132-5 is formed in a disk shape, and a coupling rod 132-51 is formed on one side. The coupling rod (132-51) is coupled to the magnet groove (132-21) of the second magnet (132-2). This is to rotate the second magnet 132-2 when the disk 132-5 rotates. The coupling rods 132-51 of the disk 132-5 are not limited to those shown in FIG. 8 and may be variously modified. A handle 132-52 is formed in the center of the disk 132-5. The handle 132-52 serves to allow a person to manually rotate the disk 132-5 to move it.

In FIG. 9, (a) shows that the first magnet 132-1 and the second magnet 132-2 are stacked to have opposite polarities, and (b) shows the first magnet 132-1 and the second magnet 132-1. It shows that the magnets 132-2 are stacked to have the same polarity. As shown in (a), when the first magnet 132-1 and the second magnet 132-2 are stacked with opposite polarities, the magnetic force only affects the inside, so the magnetic force does not apply to the outside, so the magnetic force with the attachment surface 10 It weakens and leaves. On the other hand, when the first magnet 132-1 and the second magnet 132-2 are stacked with the same polarity as in (b), the magnetic force with the attachment surface 10 increases and is fixed as the magnetic force increases to the outside.

Referring back to FIG. 1 , the work light 100 for blocking blue light according to an embodiment of the present invention may further include a three-way switch 140 . The three-way switch 140 is formed in the lighting unit 110 and the attachment unit 130 , respectively, and serves to block the current flowing through the lighting unit 110 . For example, the three-way switch 140 is formed in the lighting unit 110 and the attachment unit 130 and can be used from both sides. In this case, when the 3-way switch 140 on either side of the lighting unit 110 and the attachment unit 130 is turned on, the 3-way switch 140 on the other side can be turned off. Accordingly, after the operator attaches the work light 100 for blocking blue light according to various positions and heights, it can be easily turned on and off through the 3-way switch 140 .

FIG. 10 is an exemplary view for explaining that a waterproof part is added to the work light for blocking blue light according to FIG. 1 .

Referring to FIG. 10 , the work light 100 for blocking blue light according to an embodiment of the present invention may further include a waterproof unit 150 . The waterproof unit 150 is formed on the electric wire connected to the lighting unit 110 to waterproof the electric wire. The inside of the lighting unit 110 is in a vacuum state, and heat is generated by the LED 111 , so that external moisture or water seeps through the wire coating. For example, the waterproof part 150 cuts the wire and forms a soldering part 151 for soldering the cut first wire on one side and the second wire on the other side. Thereafter, the first wire and the second wire form a glue portion 152 , which is sealed using glue on the surrounding covering portion including the solder portion 151 . Thereafter, the injection unit 153 is formed to seal the outside using an injection material in a state in which the glue portion 152 is cured. Accordingly, the waterproof unit 150 prevents the inflow of air inside the lighting unit 110 and minimizes the voids inside the electric wire so that moisture does not permeate.
