DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for illuminating by using a light emitting diode (hereinafter, referred to as an LED) as a light source, for example, a runway warning light used for a runway or a taxiway at an airport. The present invention relates to a lighting device capable of improving workability such as light source replacement work and maintenance accompanying the life of an LED.

[0002]

2. Description of the Related Art Conventionally, an incandescent light bulb has been used as a light source in a lighting device in which right and left light emitting portions are alternately blinked, for example, a runway warning light used for an airport runway or taxiway. Light sources using long-life LEDs (light-emitting diodes) have been widely used.

A runway warning light using such an LED generally constitutes a lamp body, and has a housing having a cover which can be opened and closed on the back side, and a plurality of housings provided inside the housing. The two light emitting units on the left and right, which are mounted adjacent to each other, a fan unit for cooling the heat of the light emitting unit, and the like. And a power supply circuit unit and the like on which electronic circuits and the like necessary for the system are mounted.

In the above structure, when the driving of the light emitting unit is controlled by the power supply circuit unit, the two right and left light emitting units are turned on and off alternately, and at the same time, the light from the light emitting unit is provided on the front side of the housing. The light is transmitted through the irradiation opening and irradiated to the outside. This allows the pilot of the airplane to recognize the guidance to the runway, the guidance at the time of departure or landing, or the guidance to the invasion route, etc., by the light from the runway warning light.

When the runway warning light is turned on, the L
The amount of heat generated by the ED is small, but when a plurality of LEDs are connected to each other and mounted on a board as in the light emitting section described above,
Since the heat is mutually transferred, the temperature easily rises. For this reason, when the luminous intensity of the runway warning light is set to the maximum, the LED becomes hot, and as a result, the LED causes a decrease in luminous intensity, a decrease in allowable current, or a decrease in reliability or life. . Therefore, in order to prevent such a problem from occurring, the fan unit provided inside the housing blows and cools the light emitting unit to prevent the LED from becoming hot.

By the way, considering the life of various electronic components such as an LED and a power supply circuit mounted on the runway warning light, these various components have different lifespans.
In particular, the life of the LED of the light emitting section is longer than that of the incandescent light bulb as another light source, but is shorter than that of the power supply circuit component and the like. In addition, among a plurality of LEDs, the life of each LED varies.

Therefore, in order to secure a normal lighting state, it is necessary to replace the LED whose life has expired with a new LED in the light emitting section.
The number of replacements for D is inevitably greater than the number of replacements for the other power supply circuit components and the like due to the difference in the service life. For this reason, conventionally, there has been a strong demand for an improvement in the workability so that the LED replacement work can be performed simply and quickly. However, in the above-mentioned conventional runway warning light, when replacing the LED, the worker opens the lid on the rear side of the housing constituting the runway warning light and performs the replacement work. The internal configuration of the is a light emitting unit with an LED disposed in the front part and a power supply circuit part in the rear part,
In addition, since the electronic circuit components and other various electronic components in the power supply circuit section are arranged separately, when replacing the LED in front, the power supply circuit components and the like must be once moved outside the lamp body. Must be removed. Therefore, there has been a problem that the LED replacement work is complicated and troublesome, and the workability cannot be improved.

Only different portions will be described. The runway warning light 1 according to the present embodiment is configured such that, in the terminal block 28 provided in the first embodiment, the angle of the plane (mountain side portion) to which the connector 27 is attached is set to a suitable angle that facilitates work, For example, it is different from the above-described embodiment in that it is formed at 10 degrees to 80 degrees.

That is, as shown in FIGS. 4 and 5, the terminal block 28 has an angle of a surface on which the connector 27 is attached.
For example, it is formed at an angle of 10 degrees to 80 degrees, and is attached near the component storage opening 4C of the housing 4A. Other configurations are substantially the same as those of the first embodiment.

By removing the connector 27, the electrical connection can be released. Thereby, workability can be further improved.

The runway warning light 1 shown in FIG.
Since the terminal block 28 is installed slightly higher than the runway warning light 1 shown in FIG. 4, it is effective in improving workability.
