Hereinafter, through the preferred embodiment of the accompanying drawings, the function, configuration and operation of the light collecting LED lamp of the present invention will be described in detail. However, drawing protection for components having the same function shall be used unified.

FIG. 1A is a schematic side view illustrating a condensing of a lamp block body employed in a condensing LED lamp according to an embodiment of the present invention, and FIG. 1B is a schematic front view showing condensing of the lamp block body shown in FIG. 1A.

In the condensed LED lamp according to the preferred embodiment of the present invention, the LED 12 is installed on the rear surface of the plurality of convex lenses 11 arranged on a plane, and the LED 12 emits the light emitted from the convex lens ( 11 includes a lamp block body 10 in which LEDs are arranged to be refracted and condensed in front of the convex lens 11 so that the LEDs are arranged at or away from the center of the convex lens 11.

In this case, the front surface of the convex lens 11 is formed with a convex curved surface, and the rear surface has a flat or convex curved surface. In addition, the convex lenses 11 arranged on a plane may be formed such that each convex lens 11 is arranged at a predetermined interval on the front surface of the lens panel 1 having a rear surface formed in a plane.

Meanwhile, the LED 12 is a module in which one or a plurality of light emitting diode elements are mounted on a circuit board for supplying power, and is installed away from the rear surface of each convex lens through a heat sink, which will be described later.

On the other hand, when the thickest part of the convex lens 11 is the center of the convex lens, and the virtual line lowered perpendicularly to the back surface of the lens panel 1 at this center is the center line C, the LED 12 is installed. The position is arranged off the center line for each convex lens so that the light L emitted from the LED 12 passes through the corresponding convex lens 11, and then, at one point in front of the lens panel 1, that is, the focal point F. ) Is configured to converge to the light.

For example, as shown in FIG. 3, when five convex lenses 11 are formed in the long lens panel 1, the LEDs of the central convex lenses 11a positioned at the center of the lens panel 1 are formed. Reference numeral 12 is located at the center of the central convex lens 11a in accordance with the center line C of the central convex lens 11a. On the other hand, the LEDs 12 of the convex lenses 11b formed on both sides of the central convex lens 11a are located outward from the center of the convex lens 11b. In addition, the LED 12 of the convex lens 11c arranged at the outermost side is located further outward from the center of the convex lens 11c. That is, the LEDs 12 of the convex lenses 11b and 11c formed around the central convex lens 11a have the respective convex lenses 11b and 11c as the convex lenses 11b and 11c deviate to the outside of the central convex lens 11a. 11b, 11c) to be located more outward on the center line.

As a result, the light L emitted from the LED 12 of the central convex lens 11a goes straight through the thick center of the central convex lens, and the light L of the convex lens 11b is positioned above and below the central convex lens 11a. The light L emitted from the LED 12 is refracted at a small convex angle toward the focal point F while passing through the convex lens 11b, and is emitted from the LED 12 of the convex lens 11c formed at the edge. As the light L is positioned further outward from the center of the convex lens 11c, the angle of refraction of the light passing through the convex lens 11c is increased to be focused.

This principle of refraction, as shown in Figure 2, after the light (L) emitted from the LED 12 is vertically incident into the interior of the convex lens 11, it passes through the surface of the convex lens and is emitted into the air This is because the curved surface of the convex lens, which is relatively denser than air, is emitted with a refractive angle A larger than the incident angle B.

The angle of refraction A is fixed according to the material of the convex lens, but as the LED 12 is positioned away from the center of the convex lens 11, that is, the incident light is incident closer to the edge of the convex lens 11. Since the inclination of the contact surface with respect to the surface of the convex lens is changed as much as possible, the light passing through the convex lens converges toward the focal point.

Therefore, as shown in FIG. 1A, since the light passing through the convex lens 11 is collected at the focal point F, the luminance of the focused portion is increased. It has a relatively low brightness, and even if a low-cost low-brightness LED is used in the condensing LED lamp according to an embodiment of the present invention, it is possible to obtain a high brightness from the focus by the condensing, the aviation obstacle requiring high brightness It will be widely used in streetlights.

On the other hand, Figure 3 is an exploded perspective view of the lamp block body employed in the condensing LED lamp according to an embodiment of the present invention, Figure 4 is a front view of the heat sink employed in the lamp block shown in Figure 3, Figure 5 is a view 4 is a plan view of the heat sink shown in FIG.

In order to control the arrangement interval of the LEDs, the lamp block body 10 includes a lens panel 1 having convex lenses 11 arranged side by side, and an LED 12 fixed to the rear surface of the lens panel 1, It includes a heat sink (2) for radiating high heat.

Specifically, the heat dissipating plate 2 is slidingly coupled to the body piece 21 and the lens panel 1 in which the long holes 211 are formed in the longitudinal direction to face each convex lens so as to adjust the position of the LED, and the lens panel ( Left and right coupling pieces to form the LED 12 and the separation space 212 is installed on the back and the long hole 211 of the 1).

At this time, the body piece 21 has a plate shape installed in parallel with the rear surface of the lens panel, the body piece 21 is formed with a long hole 211 is mounted on the LED according to the arrangement of the lens panel. That is, when the convex lenses 11 are arranged in the vertical direction in the lens panel 1, the long holes 211 formed in the body piece 21 are also formed in the vertical direction, thereby adjusting the arrangement position of each LED 12. Fine adjustments can be made in the vertical direction. At this time, the LED 12 may be fixed to the long hole through the conventional fixing means such as a washer, bolt, nut, etc., the LED mounted circuit board 121.

At this time, the LEDs are respectively fixed to the position as described above on one circuit board, the circuit board is configured to be fixed to the body piece, may increase the convenience of manufacturing.

In addition, a plurality of heat dissipation fins 213 are provided on the rear surface of the body piece 21 to dissipate high heat of the LED into the air.

On the other hand, as shown in Figure 5, the left and right coupling pieces (22, 23) is formed to protrude forward from both sides of the body piece 21 vertically, the end of the sliding shape of surrounding the edge of the lens panel Grooves 221 and 231 are formed. That is, the lens panel is inserted into the sliding groove and coupled to the heat sink 2, and may be more firmly fixed by a bolt or the like coupled to the sliding groove and the lens panel.

In this case, the separation space 212 is secured between the LED 12 where the high heat is generated by the left and right coupling pieces 22 and 23 and the rear surface of the lens panel, so that the high heat of the LED is not directly conducted to the lens panel. Will be done.

On the other hand, referring again to Figure 3, both ends of the heat sink (2) is further coupled to the closing cover (3) to prevent the inflow of foreign matter inside, the LED 12 is contaminated by external foreign matter such as dust Will be prevented. Such a finish cover may be firmly fixed through bolts coupled to grooves formed at both ends of the heat sink.

In the condensed LED lamp 100, a plurality of the lamp block bodies 10 are arranged on an arc so that the light emitted from the lamp block bodies 10 converges at one focal point in order to obtain higher luminance.

That is, each lamp block body 10 has a radius of curvature with a distance between the convex lens 11 and the focal point F so that the focal points focused through the convex lenses 11 of the respective lamp block bodies 10 overlap each other. It is arranged on the arc.

To this end, the lamp block body 10 is fixed to the floor frame (F1) using a grid fixing fixture (F3) to stand. In addition, by combining the ceiling frame (F2) in the upper portion of the lamp block body 10 using a grid fixing fixture it can be firmly fixed to each lamp block body.

On the other hand, Figure 8 is a plan view of a heat sink according to another embodiment of the present invention.

In order to fill the space between the vertically parallel lamp block body, left and right coupling pieces 22 and 23 of the heat sink 2 are formed with left and right guide pieces 24 and 25 having an arc cross section. In the left guide piece 24 or the right guide piece 25, a cover piece 26 contacting the end of the right guide piece or the left guide piece of the neighboring lamp block body may be further extended.

That is, the left and right guide pieces 24 and 25 having circular arc cross-sections concave toward the neighboring lamp block body are formed at the ends of the sliding grooves 221 and 231 of the left and right coupling pieces 22 and 23, and the left guide is extended. A cover piece 26 is further formed on either of the piece 24 or the right guide piece 25 so that the ends of the right guide piece or the left guide piece of the neighboring lamp block body are in contact with the rear surface.

As a result, the space between the lamp block bodies arranged in an arc shape can be prevented to improve appearance and increase the area exposed in the air, thereby obtaining a large heat dissipation effect.

Furthermore, the left and right coupling pieces 22 and 23 or the left and right guide pieces 24 and 25 may further include heat radiating fins 27 facing outwards. In this case, the high heat of the LED can be more effectively radiated into the air, thereby more effectively preventing the damage of the LED due to red light.
