Description

AIR CRAFT WARNING LAMP HAVING RADIATION AND SUPPORT STRUCTURE OF HIGH EFFICIENCY}

The present invention relates to aeronautical obstacles, and more particularly, to aeronautical obstacles having a structure capable of stably supporting the light emitting sphere while radiating the heat of emission of the light emitting sphere for the identification of the aviation obstacle to the outside effectively.

Aviation obstacles, etc., are light emitting devices so that obstacles can be identified to prevent collisions of aircraft in advance, and are mainly installed in high-rise buildings, overhead ship supports, and protruding terrain obstacles.

In general, the aviation failure lamp is provided with a lamp such as an incandescent bulb or a halogen bulb, these lamps are not only very poor shock resistance, but also has the disadvantage of excessive power consumption and easy installation and maintenance.

As an alternative to this problem, Korean Utility Model Registration No. 287853, Patent Publication No. 2001-106392, etc. discloses a technique for arranging an LED (Light Emitting Diode) to form a cylindrical shape as a whole for use as a lamp for aviation obstacles.

However, the conventional aviation failure lamp using the LED has a vulnerability that the luminous efficiency is lowered due to its weak heat dissipation structure, although the brightness of the LED changes depending on the temperature sensitively due to the characteristics of the semiconductor.

In addition, there is a fear that the fixed state of the LED lamp is mounted by a screw-type socket with respect to the body of the aviation obstacle lamp may be unstable, and the circuit wiring may be disconnected due to the shaking of the LED lamp by external impact.

The present invention was devised to solve the above problems, and has a light emitting device mounting structure capable of smoothly dissipating heat generated from the light emitting port, and an aviation obstacle having a structure symmetrically supporting the heat dissipating structure with respect to the body. The purpose is to provide.

The following drawings attached to this specification are illustrative of the preferred embodiments of the present invention, and together with the detailed description of the present invention to serve to further understand the technical spirit of the present invention, the present invention is a matter described in such drawings It should not be construed as limited to.

It includes a heat dissipation block 102 and a support rod 103 for supporting the heat dissipation block 102 with respect to the body portion 100.

The body part 100 serves as a base on which the light emitting device 101 is installed, and provides a mounting part 100a fixed to various aviation obstacles such as overhead line support. Here, the body portion 100 is not limited to that shown in the drawings can be modified in various forms, of course.

The light emitting device 101 is a lamp of an LED array providing a light emitting surface having a cylindrical shape. As shown in FIG. 2, a rectangular flexible printed circuit board 101a in which a plurality of LEDs are arranged at regular intervals is shown. It is formed by rolling in this cylindrical shape. According to the light emitting device 101 having such a structure, a plurality of lead type LEDs or SMD type LEDs may be inserted into the flexible circuit board 101a collectively using a predetermined device and then soldered automatically.

The light emitting hole 101 is rolled to surround the outer circumferential surface of the heat dissipation block 102 to form a cylindrical shape and mounted on the heat dissipation block 102 at the same time. Here, in order to maintain the shape of the cylindrically-rolled light emitting device 101, the present invention has a connecting piece (see 101c in FIG. 3) for connecting the columns of LEDs disposed near both ends of the flexible circuit board adjacent to each other when rolling. In addition, it may be further provided. A through hole 101d into which the LED is inserted is formed in the connection piece 101c at regular intervals corresponding to the LED rows near both ends of the flexible circuit board 101a.

According to such a structure, the light emitting hole 101 and the heat dissipating block 102 are brought into contact with each other so that heat dissipation can be prevented, and the wiring area of the inner circumferential surface of the light emitting hole 101 is prevented from directly contacting the outer circumferential surface of the metallic heat dissipating block 102. Can be.

In addition, the heat dissipation and insulation efficiency may be further increased through an insulating member (see 108 of FIG. 5) in a space between the wiring area of the inner circumferential surface of the light emitting hole 101 and the outer circumferential surface of the heat dissipation block 102.

Fasteners 102b for fastening the supporting rods 103 are formed at both end surfaces of the heat dissipation block 102. The fastener 102b is coupled to the ends of the support rods 103 extending vertically from the top and bottom of the heat dissipation block 102 to fix the heat dissipation block 102 to the body portion 100. Here, a screw structure is formed on the inner circumferential surface of the fastener 102b so that an end portion of the support rod 103 may be screwed together, but the present invention is not limited thereto.
