BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention is described based on matters specific to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

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.

FIG. 4 shows an example of the light distribution characteristics of an LED 3 having an elliptical light distribution characteristic.
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.

The present embodiment relates to an LED foot light mounted on the wall 1, wherein the transparent cover 10 is mounted by projecting forward from a window hole 9 formed in a plate 8 fixed to the wall 1 with screws 7. LED in transparent cover 10
3 and projecting forward from an opaque cover member 5 detachably attached to the front side of the plate 8
And an LED foot light in which the upper part of the transparent cover 10 is covered by the eaves 6. In addition, the transparent cover 10
For example, a small outwardly extending locking claw 1 is provided at the base end of the transparent cover 10.
1 is formed, and is attached by locking the locking claw 11 to the back of the edge of the window hole 9. Further, on the back surface of the cover member 5, a locking portion 12 that is lightly locked to the upper and lower edges of the plate 8 is formed, and the like.
Is detachably attached to the front side of the plate 8.

According to this structure, the light from the LED 3 can be distributed to the feet by reflecting the light from the lower surface of the eaves 6, so that the light distribution characteristics to the feet can be improved, which is suitable for safe passage lighting at night. . Further, since the LED 3 is covered with the transparent cover 10, there is no possibility that the LED 3 is touched and an external force is applied to the LED 3. In particular, when the LED footlight is installed on the wall 1, the cover member 5 remains detached from the plate 8 until the cover member 5 is finally attached to the plate 8. LED3 by
Is protected, there is no possibility that an external force is applied to the LED 3 carelessly.

The present embodiment relates to an LED foot light mounted on the wall 1, wherein the plate 8 is fixed to the wall 1.
Circuit board 14 on which lighting circuit components 13 are mounted
Is fixed by appropriate means, and the lower edge of the LED board 4 connected to the lighting circuit board 14 via the lead wire 16 and having the LED 3 mounted thereon is the lower edge of the opening hole 17 formed on the front surface of the block 15. Locked to the back of the projection 18,
A transparent cover 10 is mounted so as to protrude forward from a window hole 9 formed in the plate 8 in correspondence with the opening hole 17, and the LED substrate 4 is housed in the transparent cover 10 so that the upper edge of the LED substrate 4 is It is also an LED foot light locked to the transparent cover 10. The block 15 includes a front cover 19, and the cover 19 has the opening 17 formed therein. In addition, although the upper edge of the LED substrate 4 may be simply engaged with the inner surface of the transparent cover 10,
For example, it is desirable that a protrusion is formed partially on the upper edge of the LED substrate 4, and this protrusion is inserted and locked in a small hole formed partially in the transparent cover 10.

According to this structure, the mounting structure of the LED substrate 4 can be performed with a simple structure by the locking means of locking to the convex portion 18 and locking to the transparent cover 10.
This is suitable when the substrate 4 is attached at an angle.

The plate 8 has a power outlet 20.
Are fixed in a penetrating state, and the front surface of the power outlet 20 is exposed from the opening 21 of the cover member 5. Then, the indoor power line 22 is connected to the power outlet 20, and the feed power line 23 from the power outlet 20 is introduced into the block 15 and connected to the lighting circuit board 14. The LED footlight is mounted so that the power outlet 20 and the block 15 are embedded in a hole 24 obtained by cutting a part of the wall 1.
