Abstract

The present invention relates to a beacon for irradiating light in all directions by using one LED. The beacon for irradiating light in all directions by using one LED comprises: a mount which is provided in a beacon body such that an LED light source vertically irradiates light; and a conical reflector which is provided to horizontally reflect the light vertically irradiated from the LED light source. The LED light source is provided such that an LED module is mounted coaxially with the conical reflector. The conical reflector has a curved surface at a vertex thereof such that the light irradiated from the LED light source is horizontally dispersed and reflected. The surface of the conical reflector is formed to have an aspherical shape so as to reduce an spherical aberration of light reflected from the conical reflector and irradiated to the outside and improve light collection efficiency. Therefore, although one light source is used, light collection can be efficiently performed. Due to the efficient light collection, high illuminating power can be realized, thereby irradiating light to a long distance.

Description

{Beacon} where 360 LED light is irradiated by one LED

The present invention relates to a reflector in which 360 degrees of light is irradiated by one LED. The reflector reflects light emitted in a vertical direction from a LED to a conical reflector to emit light in a horizontal direction, So that light can be irradiated to a long distance.

In general, a lighthouse is installed in the sea or land structure to identify the feature or location at night, and has a rotary or flashing light flickering type light beam that rotates the light.

In order to visually confirm the light of the lantern illuminator from any position, the position where the lantern illuminator is installed is installed in a place where the four sides are opened as much as possible. In order to illuminate the light of the lantern illuminator in all directions, Is mounted.

That is, in order to allow light to be emitted along the periphery of the light emitting device, a plurality of light sources are arranged in the circumferential direction of the light emitting device so as to perform light emission. There is a problem in that the cost is high and the maintenance is very troublesome because the number of light sources is large as well as the assemblability is poor.

Recently, in order to solve this problem, the light emitted from the light source can be emitted in a 360-degree direction on the plane using a conical reflecting mirror, and the reflection range of the light is adjusted by adjusting the position of the lens, However, there is a problem in that a method of simply reflecting light at 360 degrees can not realize a high light power.

Particularly, due to the nature of the installation site, the problem that a high luminous power can not be realized in a luminaires which need to illuminate a light to a long distance is a fatal disadvantage, and thus is practically useless.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a light changer which can illuminate light to a long distance by realizing high light power by condensing light even though one light source is used.

In order to achieve the above object, the present invention as a technical idea is characterized in that a mounting base is provided on a body of a lightening machine, and a light source is mounted so as to irradiate light in a vertical direction, Wherein the light source includes a light emitting diode (LED) module mounted on a coaxial with a reflector, the reflector including a light source for emitting light radiated from the LED light source in a horizontal direction The surface of the reflector is formed as an aspherical surface in order to reduce the spherical aberration of the light to be reflected to the outside and to increase the efficiency of light collection so as to condense the light emitted from the LED module So that the light can be irradiated to a long distance.

According to the reflector of the present invention, the light is condensed by the aspherical lens to sufficiently secure the light power, and the light emitted through the lens is horizontally reflected by the aspheric reflector to irradiate the light. Therefore, the spherical aberration is significantly reduced, It is possible to realize a high luminous power, and as a result, the light can be irradiated to a long distance, and the visibility of the light source installed in the sea or land structure can be remarkably improved.

Further, since the focal length of the lens can be shortened by using the aspherical surface, the condensing efficiency and the optical power can be sufficiently secured even if the LED module and the lens are arranged close to each other, and the volume of the light source can be reduced and the size can be reduced.

Also, by adjusting the height of the light source or by changing the surface tilt of the reflecting mirror to various shapes, it is possible to change the irradiation angle of the light reflected and reflected by the reflecting mirror, have.

The light source 30 is mounted on the mount to irradiate light in a vertical direction while being mounted on the mount, The cone-shaped reflector 40 is disposed and the light radiated from the light source in the vertical direction is refracted in the horizontal direction by the cone-shaped reflector 40 so that the light is irradiated at 360 degrees.

The light emitting device body 10 may be divided into a lower body 10a in which an electric device or the like is embedded and an upper body 10b in which the light source 30 is installed on the upper side of the lower body 10a, The upper body 10b may be assembled in a structure detachable from the lower body 10a, or may be folded to one side to open the inside.

The mounting bracket 20 is provided to house the light source 30 in the luminaire body 10. The mounting bracket 22 is horizontally provided at the lower end of the upper body 10b and a light source 30 Can be mounted.

As shown in FIG. 4, the light source 30 may be mounted on the mounting plate 22 so as to be mounted upward so as to be vertically irradiated with light. Reflected in the horizontal direction by the reflector 40 and reflected, the light is irradiated 360 degrees to the outer periphery of the light illuminator.

For this, the light source 30 may be mounted so that the LED module 32 is arranged coaxially with the center axis of the reflector 40, so that the light is irradiated to the center of the reflector 40.

The curved surface 42 is formed at the vertex of the conical shape of the reflector 40 and the surface of the reflector is formed as an aspherical surface 44 to reduce the spherical aberration of the light irradiated when the light emitted from the LED module is reflected, It is possible to increase the efficiency.

Accordingly, the light emitted from the LED module 32 can be condensed to illuminate the light to a long distance.

In addition, the light source 30 may include a lens 34 mounted on the LED module 32 to efficiently collect light emitted from the LED module to increase the light power.

At this time, the lens 34 shortens the focal distance of the LED module and the lens 34, and focuses the light emitted from the LED module so that the surface of the lens 34 is formed of the aspherical surface 36 By minimizing the distance between the LED module 32 and the lens 34, the size of the light source 30 can be reduced, and the size of the light source 30 can be made small, Can be mounted.

A cylindrical tube 50 capable of projecting light can be mounted along the side surface around which the light source 30 and the reflector 40 are mounted and the light source 30 and the reflector 40 are mounted So that foreign matter does not flow into the inside of the reflector 40 and the surface of the reflector 40 or the surface of the reflector 40 is not damaged and foreign matter is not added. .
