It is possible to mix the light emission of the above, and the desired emission color can be achieved.
FIG. 7B shows the arrangement of the red (R), green (G), and blue (B) light emitting elements inside the three chips out of the LED elements 7B of eight chips in a row. However, the inside of the other light emitting elements 7B has the same arrangement, which means that, referring to the black-painted diode mark, the light emitting elements 7B having the same arrangement of red (R), green (G), and blue (B) are one. It turns out that they are arranged every other.
The same applies when red (R) and blue (B) are lit, or when green (G) and blue (B) are lit.
The plurality of LED elements 7B may be arranged in one row or in a plurality of rows.

As another embodiment of the present invention, the LED element 7B of the special notification light source 60 is a white light emitting element that emits white light in addition to the light emitting elements of the three primary colors of red (R), green (G), and blue (B). The element (W) is included in one chip, and as shown in FIG. 10, each element of red (R), green (G), blue (B), and white (W) is arranged in a square. is there. The white light emission includes any of natural light color, white color, bluish white color, warm white color, and daylight color equivalent to sunlight.

Also in this case, similarly, by arranging at least one direction of the four chips in a row in a direction different from the direction of the other chips, it is possible to prevent a state in which one color looks strong. As one preferred embodiment thereof, as shown in FIG. 8, the LED element 7B is arranged among the red (R), green (G), and blue (B) by arranging the adjacent chips in different directions. A plurality of emission colors can be mixed, and the desired emission color can be achieved.

When emitting white light, the red LED element (R) that emits red light, the green LED element (G) that emits green light, and the blue LED element (B) that emits blue light emit white light. Although it may be configured, by providing a white (W) light emitting element, white (W) light emission can be clearly obtained.

As in (W), even when a plurality of light emitting elements emitting different colors are configured in one chip in a predetermined arrangement, and a plurality of (two or more) of these chips are arranged in a state other than a row on the light emitting unit substrate 5B. By arranging at least one direction of the chip in a direction different from the direction of the other chips, it is possible to solve the situation where one color looks strong as described above.

The luminaire 1 is attached to the upper part of a pillar installed at the end of the street and illuminates the street with the normal lighting light source 50 at night. However, when the special notification light source 60 is turned on at the same time, it is viewed from the street. A person appears to be in a state in which the white light of the normal lighting light source 50 is irradiated toward the front special notification light source 60, and the emission color of the special notification light source 60 is changed.

The left-right length of the partition plate 70 is substantially the same as the left-right width of the mounting plate 40.

The light to the upper side of the normal lighting light source 50 is blocked by the light emitting portion substrate 5 and the mounting plate 40, but the white light of the normal lighting light source 50 travels straight forward by the partition plate 70. This is prevented from reaching the special notification light source 60.
Therefore, it is possible to prevent the emission color of the special notification light source 60 from being diluted by the white light of the normal illumination light source 50, and it is guaranteed that the special notification light source 60 appears to emit light in the desired emission color. Will be done.

The special notification light source 60 is arranged in front of the normal lighting light source 50, and the light emission of the normal lighting light source 50 and the light emission area of the special notification light source 60 can be sufficiently secured so that the normal lighting light source 50 can be used at night. It is possible to illuminate a required part such as a street, and the emission color of the special notification light source is clearly visible, so that the visibility of the emission color of the special notification light source 60 is improved.
In order to obtain this effect, in the opening 2A of the main body 2 having a large length in the front-rear direction with respect to the width in the left-right direction, the arrangement area of the special notification light source 60 on the front side and the light source 50 for normal lighting on the rear side is set. Of the length in the front-rear direction, the area occupied by the special notification light source 60 on the front side partitioned by the partition plate 70 is 20% to 40%, and the light source for normal lighting on the rear side partitioned by the partition plate 70. The area occupied by 50 is 60% to 80%.

In the luminaire 1, an illuminance sensor SS for detecting the illuminance of the peripheral portion thereof is attached to a daylighting hole formed in the rear wall of the main body 2 in a state where the tip is housed in a protective cover 27 having a translucent tip. There is.
