Description

LED warning light {LED guard light}

The present invention relates to a boundary light used to monitor a certain area as a whole at night, more specifically, it can be quickly turned on, life is semi-permanent, and can greatly save energy, as well as high illumination at a long distance Is an LED boundary light that can transmit light to a narrow and long illumination area.

Conventionally, military or security lighting fixtures, which are used to monitor a certain area at night, especially to monitor the intrusion of outsiders around barbed wires, are used to distribute light emitted from the lamp evenly in all directions (360 degrees). Circular floodlights with lamp-shaped reflectors are used.

Such conventional floodlights mainly use high-brightness discharge lamps, and the light-projecting surface uses glass or acrylic having excellent transmittance, and is installed in an optimal position to enhance lighting effect regardless of any region or place. It is arranged to be spaced vertically or horizontally at the pillar or wall and projected downward.

In practical applications, however, it is often necessary to increase the lighting range in a specific direction and to reduce the lighting range in the remaining directions. For example, in the case of illuminating the barbed wire, it is preferable that the lighting range is wide and the effect is good in the longitudinal direction in which the barbed wire is extended, whereas in the direction perpendicular to the longitudinal direction of the barbed wire, light pollution is caused to the surrounding environment. It is recommended that the lighting range be small to avoid this.

However, the circular floodlight as described above has a circular illumination area, which does not satisfy the conditions described above, and at the same time to install a lot of floodlights in the longitudinal direction of the barbed wire unnecessarily to solve this problem The installation angles of the flood lamps are set differently to obtain sufficient lighting effects. Therefore, there is a problem that the installation cost is increased. In addition, there is a problem that the luminance of the central portion and the peripheral portion of the illumination region of the floodlight is greatly different.

In addition, in the case of military lighting equipment, it is usually installed in a mountainous area or a coastal area, which is difficult to maintain and repair, and thus requires a long life as possible, and illuminance at a long distance to easily check for intrusion and abnormality. There is a need to be high.

However, as a light source used in such floodlights, lamps such as metal halide lamps, sodium lamps and halogen lamps are used, which consume a lot of electricity, have a short service life, take a long time to turn on, and especially maintenance. There are disadvantages such as high cost and pollution.

Therefore, in recent years, LEDs having low power consumption and semi-permanent life characteristics have been applied as light sources in order to improve illumination and reduce energy. However, the luminaire using LED also increases the brightness by overlapping adjacent lighting areas, and because the distribution of light intensity is not uniform, the average brightness is lowered. There is this.

Therefore, the present invention has been made to solve the above problems, it is possible to quickly turn on, the life is semi-permanent, and can greatly save energy, as well as the effect of concentrating light rays and excellent brightness and uniformity at a long distance Its purpose is to provide an LED boundary lamp that can deliver light accurately to a narrow and long illumination area with high illumination.

At this time, the power is a commercial AC power is converted to a DC power in a separate power supply device installed outside the boundary light, the DC power is applied to the LED lamp assembly (3).

6 is a view showing the results of the measurement of illuminance measured after the installation of the boundary lamp according to the present invention at a height of 3m, if you look closely at this, if you connect the same illuminance value (for example 30) in the formed illumination area is uniquely approximately elliptical You can see that this is achieved. This is a result of the influence of the first LED lamp module. In addition, unlike a lamp to which a conventional LED is applied, the illuminance at the center of the illumination region is much higher than the illuminance at the periphery. This is an effect obtained by the influence of the second LED lamp module.

Accordingly, it can be seen that the LED boundary lamp according to the present invention can accurately transmit light to a narrow and long illumination area, and is very suitable for preventing pollution of light in the surrounding environment.
