The light source 222 is mounted on the circuit board 224 in the form of an LED package. The light source 222 is disposed in plurality along the outer surface of the support member 230.

A pattern circuit is formed on the circuit board 224 to be electrically connected to the light source 222. The circuit board 224 is provided as a flexible circuit board so as to be closely supported along the outer surface of the support member 230. The circuit board 224 is formed in a closed loop shape to surround the outer periphery of the support member 230 along the outer surface of the support member 230.

The support member 230 supports the light source module 220. The support member 230 of the present invention is provided with a material having high thermal conductivity such as aluminum to support the light source module 220 and to dissipate heat from the light source module 220.

Next, the lens unit 240 according to the first embodiment of the present invention includes a reflector 242 and a lens member 244. The lens unit 240 is spaced apart from the support member 230 with the light source module 220 interposed therebetween. In addition, the lens unit 240 of the present invention is formed in a closed loop shape to surround the light source module 220 and the support member 230.

The reflector 242 includes an upward reflector 242a and a downward reflector 242b which are disposed based on the light source 222. Here, the upward reflecting portion 242a and the downward reflecting portion 242b are disposed upside down symmetrically with respect to the light source 222.

The upward reflecting portion 242a and the downward reflecting portion 242b have a reflective surface having a predetermined inclination angle. Here, the reflective surface of the reflector 242 may have a flat plate surface as in the present invention, or may have a plate surface having a predetermined radius of curvature. According to the change of the plate surface of the reflective surface, the ratio of the light incident from the light source 222 to be guided in the direction of the optical axis irradiated perpendicular to the installation surface of the light source 222 may be changed. In addition, the reflective surface of the reflector 242 may be totally internal reflection, or may form reflected light through the optical reflective coating on the back.

That is, the lens member 244 has a convex lens shape provided convexly in the irradiation direction of the light irradiated from the light source 222. The lens member 244 converts into parallel light when the light is emitted to the outside to prevent the light from spreading. As the lens member 244 converts the light into parallel light, the light passing through the lens member 244 has a straightness.

5 is an exploded perspective view of the lighting assembly according to the second embodiment of the present invention, FIG. 6 is a combined perspective view of the lighting assembly shown in FIG. 5, and FIG. 7 is a sectional view taken along the line VII-Ⅶ of FIG. 6. .

5 to 7, the lens unit 300 of the brightener 1 according to the second embodiment of the present invention includes a first lens member 320 and a second lens member 340. .

The first lens member 320 is disposed adjacent to the light source module 220. The first lens member 320 of the present invention includes a reflector 322 and an exit lens unit 324.

As in the first embodiment of the present invention, the reflector 322 includes an upward reflector 322a and a downward reflector 322b having a predetermined inclination angle upward and toward the light source 222. The reflector 322 according to the second embodiment of the present invention may have a reflective surface having a predetermined radius of curvature, as in the first embodiment.

The exit lens unit 324 is disposed adjacent to the second lens member 340 at a predetermined interval. The scattering lens unit 324 guides the light in the x-axis direction irradiated from the light source 222 and the light guided from the y-axis direction to the optical axis direction in the x-axis direction to the second lens member 340. Exit.

The second lens member 340 is disposed to have a predetermined distance from the first lens member 320, and converts the light emitted through the exit lens unit 423 into the collimated light. The second lens member 340 of the present invention includes an incident lens unit 342 and a refractive lens unit 344.

The incident lens unit 342 is disposed to face the emission lens unit 324. The incident lens unit 342 receives light emitted through the exit lens unit 324 to guide the refractive lens unit 344.

Like the lens member 244 of the first embodiment of the present invention, the refractive lens unit 344 is convexly provided in the x-axis direction in the optical axis direction at a predetermined interval with respect to the reflector 322. The refractive lens unit 344 converts the light guided by the incident lens unit 342 into parallel light so as to have straightness without spreading.

On the other hand, the first lens member 320 according to an embodiment of the present invention is divided into a plurality arranged. That is, as shown in FIGS. 5 and 5, the first lens member 320 is divided into three with a 120 degree interval. The reason why the first lens member 320 is divided into a plurality of the plurality of lenses is arranged to overcome manufacturing difficulties. Of course, if the first lens member 320 is not difficult to manufacture, the number of divisions may be different.

However, when the first lens member 320 is divided into three and disposed, when the light from the light source 222 passes through the space between the first lens members 320, each first lens member 32 is separated. The light is concentrated by the side of the side. For example, the light passing through the side surface of each first lens member 320 may be reflected on the side surface of each first lens member 320, and a noise phenomenon may occur in which the light density of the region is increased.

Accordingly, in order to prevent a noise phenomenon in which light is concentrated between the first lens members 320, the light density passing through each side of each first lens member 320 should be uniform. Therefore, the scattering surface 326 is formed on the side of the first lens member 320 of the present invention to guide the light uniformly to the second lens member 340.

The light register 1 according to the present invention configured as described above is mainly used for being accommodated inside a fixture for guiding a lighthouse or a navigation path for safe operation of a ship or aircraft. Such illuminator 1 should be irradiated with high intensity light so as to secure a sufficient field of view for the location and danger area of the land of a ship or aircraft in operation at night.

According to this configuration, the operation process of the equalizer 1 according to the first and second embodiments of the present invention will be described below.

First, an operation process of the equalizer 1 according to the first embodiment of the present invention will be described. When an operation signal is applied to the equalizer 1, power is supplied from the power supply unit to the lighting assembly 200. When the power is supplied to the lighting assembly 200, light is emitted from the light source 222 mounted on the circuit board 224.

Light emitted from the light source 222 is irradiated in the x-axis direction and the y-axis direction. Here, the light irradiated in the y-axis direction is guided by the reflector 242 in the x-axis direction, which is the optical axis direction.

The light guided by the light source 222 and the reflector 242 is converted into parallel light by the lens member 244 and irradiated to the outside of the illuminator 1.

Meanwhile, referring to the operation process of the equalizer 1 according to the second embodiment of the present invention, the y-axis direction from the light source 222 is the same as the operation process of the equalizer 1 according to the first embodiment of the present invention. The irradiated light is guided in the optical axis direction which is the x axis direction.

Then, the light passing through the exit lens unit 324 of the first lens member 320 is guided to the incident lens unit 342 of the second lens member 340. In this case, the light passing through the space between the plurality of first lens members 320 may have a uniform light density on the scattering surface 326 formed on the side surface of each first lens member 320.

Then, the light guided to the second lens member 340 is converted into parallel light by the refractive lens unit 344 and irradiated to the outside of the illuminator 1.

Thus, the light irradiated from the light source may be guided in the direction of the optical axis irradiated perpendicularly to the installation surface of the light source through the reflectors disposed upward and downward, thereby increasing the brightness and luminance of the light.

In addition, by improving the structure of the illuminator so that the light guided through the reflector in the optical axis direction is converted into parallel light and irradiated to the outside, the straightness of the light irradiated from the illuminator can be increased.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
