れる。The illustrated embodiment is an LED foot light mounted on a wall 1 and illuminating a lower surface 2 of a hallway, and is a so-called elliptical light distribution in which the light distribution directional angle is set to be larger in the horizontal direction than in the vertical direction as the LED 3. The LED footlight with the characteristic is mounted. An LED footlight mounted on the wall 1 and illuminating the corridor lower surface 2 has a so-called elliptical light distribution characteristic in which the light distribution directional angle is set to be larger in the horizontal direction than in the vertical direction as the LED 3. A plurality of LED foot lights are mounted on the LED board 4 so as to be in the same direction as one another in a row. An eaves portion 6 protruding forward is formed on a cover member 5 made of an opaque resin provided on the surface, and the LED 3 provided on the lower surface (light-reflective) of the eaves portion 6 is formed by the method of the wall 1. The LED 3 is directed downward in the direction of θ = 30 to 50 ° with respect to the line direction, and the LED 3 has a height of about 20 to 40 cm from the lower wall 2 of the hall. In addition,
In the present embodiment, six LEDs 3 are arranged in a row in the horizontal direction, and two LEDs 3 are arranged on the upper row side.

Light distribution characteristics of 90 ° are shown. In the figure, the solid line represents the light distribution characteristics in the vertical direction, and the dashed line represents the light distribution characteristics in the horizontal direction.
By setting the cross-sectional shape of the transparent lens constituting the LED 3 to be an ellipse, the light distribution directional angle is set to be larger in the horizontal direction than in the vertical direction. FIG. 3B shows a schematic light distribution characteristic of the present foot light using the LED 3 having this characteristic, and the light distribution characteristic in the longitudinal direction of the corridor lower surface 2 can be widened. Thus, irradiation can be effectively performed in the longitudinal direction of the corridor lower surface 2. On the other hand, FIG. 3A shows the light distribution characteristics when an LED having a general circular light distribution characteristic is used, and the light distribution characteristics in the longitudinal direction of the corridor lower surface 2 become narrow, and the practicality is poor. . When the LEDs 3 having the elliptical light distribution characteristics are used, a plurality of LEDs 3 can be mounted on the LED substrate 4 in the same direction as each other, so that the LEDs 3 can be easily mounted on the LED substrate 4. Further, in the case of a general installation situation in which the LED 3 is set at a height of about 20 to 40 cm from the corridor lower surface 2, the LED 3 provided in the lower surface of the eave portion 6 has θ = 30 below the normal direction of the wall 1. When oriented in the direction of ５０50 °, a suitable light distribution to the corridor lower surface 2 is obtained.
