The present invention relates to an LED lamp that uses an LED as a light source, and more particularly, to an LED lamp that can easily attach and detach an LED module to a main body, thereby facilitating installation and maintenance.

LEDs are becoming popular in recent years due to their advantages such as high illuminance, semi-permanent life span and low power consumption.

The LED lighting device includes a main body in which an LED module and an LED module are mounted in front and a power supply is built in, a cover covering both sides of the main body, and a cover coupled to the front of the main body to cover the LED module.

Japanese Patent Application No. 10-0938888 discloses an integrated LED fluorescent lamp lighting device in which a slide groove is formed in the main body and the LED module is slidably inserted into the slide groove of the main body.

The conventional technique of slidably coupling the LED module to the main body requires a space for arranging the LED module in the longitudinal direction beside the main body and requires a space for holding the LED module by hand It is troublesome to push the LED module into the slide groove of the main body several times while changing the position. In order to couple or separate the LED module to the main body, it is troublesome to separate the cover coupled to both sides of the main body.

Another conventional technique disclosed in Korean Utility Model No. 20-2016-0001457, "Ceiling-mounted LED lighting fixture ", tightens the LED module with a bolt to the bottom of the main body.

The conventional technique of connecting the LED module to the main body with the bolt requires a fastening tool such as a bolt and a screwdriver, and it takes a lot of time and manpower to install and disassemble the LED module because the LED module is tightened by bolts.

The present invention was conceived to solve the problems of the prior art LED fixture as described above. The present invention can be easily achieved simply by pushing the mounting plate with the LED module mounted thereon into the opening of the main body and holding the mounting plate with a finger or a stick And to provide an LED lamp which is easily separated when pulled.

Another object of the present invention is to provide an LED lamp which can be easily combined with and detached from the main body when the cover is manually pressed to reduce its width.

As shown in the drawing, an LED lamp according to the present invention includes a main body 10, a lid 20, an LED module 30, a mounting plate 40, and a cover 50.

In the following description of the present invention, the directions are determined on the basis of the drawings, and the direction in which the illumination is irradiated is forward and the direction opposite thereto is rearward.

The main body 10 has a "C" shape, and a power supply 60, a connector, and the like are mounted inside.

The body 10 is manufactured by an extrusion method.

On both inner surfaces of the main body 10, engaging pieces 11 protrude in the longitudinal direction, and fitting grooves 13 are formed.

The lid 20 is coupled to the left and right sides of the main body 10 to cover both side openings of the main body 10.

The LED module 30 includes a PCB 31 and a plurality of LEDs 33 mounted on the PCB 31.

The LED module 30 is mounted on the front surface of the mounting plate 40 and inserted into the front of the main body 10 to be coupled.

On the rear surface of the mounting plate 40, a fitting piece 41 protrudes on both sides in the longitudinal direction.

The fitting piece 41 is coupled to the coupling piece 11 of the main body 10 in an interference fit. The distance between the two engaging pieces 11 formed on both sides of the main body 10 is equal to or shorter than the distance between the outer side surfaces of the two engaging pieces 41 formed on both sides of the mounting plate 40, And the piece 41 is inserted and coupled between the two engaging pieces 11 in an interference fit manner.

At this time, in order to prevent the mounting plate 40 from being separated from the main body 10 due to an accidental impact, a circular engaging portion 42 is formed at the end of the fitting piece 41. Thus, the engaging portion 42 is engaged with the lower surface of the engaging piece 11 by a small amount.

The mounting plate (40) is provided with a charging hole (45) into which the decomposing tool is inserted. The operator can insert the fingers into the insertion holes 45 and pull them to separate the mounting plate 40 from the main body 10 and insert sticks of drivers, ballpoint pens, chopsticks, etc. into the insertion holes 45 in the oblique direction After the bottom of the bar is brought into contact with the bottom of the main body 10, the top of the bar can be lifted and the mounting plate 40 can be separated from the main body 10 in a leverage mode.

The cover (50) is coupled to the front of the main body (10) to cover the LED module (30). The cover 50 covers and protects the LED module 30 and is transparent or translucent to diffuse the light emitted from the LED module 30 to the surroundings to prevent glare.

At both side ends of the cover (50), fitting protrusions (53) protrude in the longitudinal direction.

The fitting protrusion 53 is fitted in the fitting groove 13 formed in the longitudinal direction inside the upper end of the main body 10.

The cover 50 has elasticity and is adjustable in width. The operator holds the cover 50 and presses the cover 50 into the front opening of the main body 10 with the width reduced so that the fitting protrusion 53 of the cover 50 is inserted into the fitting groove 13 of the main body 10 So that the cover 50 is engaged with the main body 10. When the cover 50 is detached from the main body 10, the cover 50 is held by the cover 50 and the width of the cover 50 is reduced so that the fitting protrusion 53 is released from the fitting groove 13, It may be removed from the opening.

The present invention includes detachment means K for easily attaching and detaching the power supply 60 for supplying power to the LED module 30 to the inner bottom of the main body 10. [

The attachment / detachment means K includes a fixing block K10 fixedly coupled to the bottom of the main body 10, a coupling block K20 provided on a side surface of the power supply, And a locking member (K30) detachably coupling the locking member (K20) to each other.

The fixed block K10 has a stepped portion K11 to which the coupling block K20 can be seated and coupled.

A pressing hole K111 is formed in the stepped portion K11.

A pressing member K12 is provided in the fixing block K10 so as to be pressed through the pressing hole K111.

More specifically, the pressing member K12 includes a pressing protrusion K121 partially exposed through the pressing hole K111 and a lower end of the pressing protrusion K121 inserted thereinto And a pressed casing (K122) for allowing the pressing protrusion (K121) to move up and down.

The pressing casing K122 is further provided with a first elastic body K123 which is in close contact with a lower end surface of the pressing protrusion K121 and is capable of applying an elastic force upward in the pressing protrusion K121.

When the pressing projection K21 of the coupling block K20 presses the pressing projection K121, the pressing projection K121 descends and enters the fixed block K10 to enter the pressed casing K122, Can slide within the fixed block (K10).

It is obvious that a separate passage is formed inside the fixed block K10 for the sliding movement of the pressed casing K122. It is obvious that the first magnet K13 and the second magnet K124 The pressed casing K122 slides in the fixed block K10 through the force of the attraction force.

More specifically, a first magnet (K13) is disposed in the lower end surface of the fixed block (K10), more precisely, a lower end surface of the fixed block (K10) connecting a virtual extension line downward along the side surface of the stepped portion And a second magnet K124 is provided on one side of the pressed casing K122, that is, in the direction of the first magnet K13.

Further, the first magnet K13 and the second magnet K124 are configured to exert attractive force with each other.

Therefore, the pressing casing K122 is not slidingly moved due to the fact that the pressing protrusion K121 is partially exposed through the pressing hole K111, so that the attraction force is not meaningful. However, the pushing protrusion K21 of the coupling block K20 The first magnet K13 pulls the second magnet K124 and the pressed casing K122 is slidably moved so that the pressed casing K122 can be slidably moved And is moved in the direction of the first magnet K13.

When the pressed casing K122 moves in the direction of the first magnet K13, the pushing protrusion K122a formed at the lower end of the pressed casing K122 operates the locking member K30, Is interposed in the locking groove K23 of the coupling block K20 to fix the coupling block K20.

More specifically, a separate space is formed at the lower end of the first magnet K13 and the second magnet K124, and the push projection K122a is positioned in the space.

That is, the push projection K122a protrudes from the lower end of the pressed casing K122 in one direction, that is, in the direction of the locking member K30. In this case, it is preferable that the length of the push projection K122a is adjusted so that the end of the push projection K122a does not exceed the first magnet K13.

When the pressed casing K122 slides in the direction of the first magnet K13 by the above operation, the pressing protrusion K121 smoothly slides over the imaginary boundary line of the first magnet K13, At this time, the locking member K30 is pressed and operated.

Before describing the locking member K30, when the locking block K20 is first described,

The locking block K20 has a locking groove K23 formed at one side thereof and a pressing projection K21 at a lower portion thereof so that when the pressing block K21 is seated on the stepped portion K11, And presses the pressing projection K121 which is partially exposed through the pressing hole K111,

The locking groove K23 has a structure in which the locking bar K33 of the locking member K30 to be described later is inserted.

Referring back to the locking member K30, the locking member K30 is provided inside the fixing block K10, more specifically inside the side of the step K11,

As shown in the drawing, a connection bar K32 is provided to be rotatable about a rotation axis K35, and a first hinge axis K34 at the lower end of the connection bar K32. A push bar K31 provided for hinge movement and a locking bar K33 provided at the upper end of the connecting bar K32 so as to be hingeable via a second hinge axis K36.

Therefore, the push bar K31 and the locking bar K33 are slidable in opposite directions by the rotation of the connecting bar K32 with respect to the rotation axis K35.

As a result, when the pressed casing K122 moves in the direction of the first magnet K13, the push projection K122a pushes the push bar K31, K11 and inserted into the locking groove K23 of the coupling block K20 so that they can be fixed to each other.

A locking device for locking the locking bar K33 more securely is characterized in that a partition wall K22 is formed in the locking groove K23 of the coupling block K20, A second pulling member K24 is provided and a fourth magnet K243 is provided at an end of the second pulling member K24.

Further, a third magnet (K331) to which attraction force with the fourth magnet (K243) is applied is further provided at an end of the locking bar (K33).

Therefore, when the locking bar K33 is inserted into the locking groove K23, the third magnet K331 at the end of the locking bar K33 and the fourth magnet K243 of the second pulling member K24 It is possible to prevent the locking bar K33 from falling out of the locking groove K23 by arbitrarily attempting to avoid falling by the attraction force.

In this case, when the locking bar K33 is separated from the locking groove K23 in the absence of the partition wall K22, 4 magnet (K243) is attached.

As described above, the fixed block K10 and the coupling block K20 are firmly fixed to each other, and the operation of separating them from each other will be described.

First, in order to separate them from each other, the safety device provided in the coupling block K20 described above must be released (the operation of separating the third magnet K331 and the fourth magnet K243 away from each other).

To this end, as described briefly above, the coupling block K20 is further provided with a second pulling member K24.

The second pulling member K24 includes a second pulling cord K241 and a second pulling clip K242 and a fourth magnet K243 provided on the second pulling cord K241.

More specifically, the second pulling cord K241 is located on the opposite side of the locking groove K23 with respect to the partition wall portion K22, and has a fourth magnet K243 and a second pulling ring K242 .

At this time, the second pulling ring K242 protrudes outside the coupling block K20.

Therefore, in order to release the safety device, the user pulls the second pulling ring K242, and by this operation, the fourth magnet K243 moves away from the third magnet K331 so that no attractive force acts on each other.

The locking bar K33 must be detached from the locking groove K23 to separate the coupling block K20 from the fixed block K10,

This is solved by ultimately placing the pressed casing K122 in place. To this end, the fixed block K10 of the present invention is further provided with a first pulling member K15.

The first pulling member K15 is similar to the second pulling member K24 and has a first pulling cord K151 fixed to the pressed casing K122 at one end and having a first pulling ring K152 at the other end, .

The first pulling ring K152 is exposed to the outside of the fixed block K10.

Therefore, when the user pulls the first pulling ring K152, the first magnet K13 and the second magnet K124 are gradually spaced apart. When the pressing projection K121 is positioned in the pressing hole K111, The pressing protrusion K121 rises due to the elastic force of the one elastic body K123 and comes in contact with the pressing protrusion K21 located in the pressing hole K111 to be partially exposed in the pressing hole K111 The coupling block K20 can not be lifted only by the elastic force of the elastic body K123 but this is one of the separation processes in which the coupling block K20 is detached from the fixed block K10 while pulling the first pulling member K15 It can be solved by external force.)

The second elastic body K37 is provided at one side of the push bar K31 (the opposite direction to the push projection K122a) to push the push bar K31 toward the push projection K122a, So that the bar K33 is retracted from the locking groove K23 and is again located inside the fixed block K10.

In addition, although the respective operations have been separately described for the sake of convenience of explanation, the respective operations occur simultaneously in conjunction with each other, and the scope of the rights should not be construed to be limited.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited thereto. Various modifications and alterations of the present invention may be made by those skilled in the art. Should be interpreted as belonging to.
