In the above-described lighting device body, the direction of the light emission center of the plurality of LEDs 2 passes through the center thereof and is parallel to the longitudinal central axis of the lighting device body in order to reduce uneven brightness on the light emitting surface of the light emitting unit 4. It is desirable to mount it so that it faces substantially upward (to be substantially perpendicular to the normal direction of the light emitting surface).

Reference numeral 7 denotes a light source power carrier line for supplying power to the light source unit 1.

The operation of the first embodiment configured as described above will be described. First, when power is supplied by the light source power carrier line 7 and the plurality of LEDs 2 attached to the light source unit 1 are turned on by the lighting circuit unit 3 (3a), the light emission center direction becomes the luminance on the light emitting surface of the light emitting unit 4. In order to reduce unevenness, the lighting device passes through the center and is directed on an axis parallel to the central axis in the longitudinal direction of the lighting device main body. Thus, the light emitting section 4 emits light from the light source section 1. At this time, since the light-emitting cover 5 covers the surface of the light-emitting unit 4, glare of the light-emitting unit light is prevented, and the reflection sheet 6 reflects light from the light source to emit light efficiently from below the light-emitting unit 4.

m, the diameter is 40 mm, the LED 2 has a diameter of 3 mm,
Twenty-four lm / w lens-equipped elements were used on one side. For the light emitting part 4, a transparent acrylic pipe having a diameter of 45 mm is used.
As the reflection sheet 6, a white diffusion sheet having a reflectivity of about 97% was used. The reflection sheet 6 and the light-emitting cover 5 were used in such a manner as to cover exactly the cylindrical half of the acrylic pipe. as a result,
At a point 60 cm vertically away from the center of the surface of the light emitting part 4, 10
Looks, from which he moved 30 cm to the right without changing the direction of the illuminometer, also obtained 10 looks (same for the left side).

The above illuminance value can be arbitrarily changed by adjusting the number of elements of the LED 2. If a higher illuminance value is desired, the number of elements will increase,
If a low illuminance value is desired, the value of the current flowing through the element may be reduced. Further, the LED 2 has a very low energy consumption of about 0.08 W in rating, and has a feature that the element itself has a long life (several hours to several hundred thousand hours) due to solid-state light emission. Therefore, the life of the conventional fluorescent lamp (about 6,000 hours)
Therefore, the number of light source replacements is greatly reduced, and the light source can be used almost without replacement.

Also, since a plurality of LEDs are used,
There is an advantage that the device can be used as it is even when a small number of elements cannot be turned on. When maintenance of the light source is required, the light source unit 1 can be removed from the lighting device main body, so that maintenance can be easily performed. Further, at present, an element having an emission wavelength having a peak in red or green has an advantage that the element is very inexpensive, so that an inexpensive lighting device that saves energy and has a long life can be obtained.
