In the conventional desk lamp, the desk lamp 100 is installed in front of the worker or diagonally to the left, as shown in FIGS. Reflective glare was generated as shown by the arrow, and the irradiated light was entering the glare zone (a 30° range centered on the line of sight). Reflective glare occurs especially when looking at paper or photographs with light selection, and when reflective glare occurs, even if there is sufficient illuminance, the contrast between the text or photographs and the paper decreases, making the text or photographs very difficult to read. This made it difficult to see and even caused stress for workers.

であつた。 As another conventional example, the one described in Japanese Patent Laid-Open No. 56-42907 is known. The device described in this publication aims to reduce the direct radiation component of the lamp itself to prevent reflected glare, and for this purpose, a second reflecting plate is provided.
In this conventional example, unless you use a special lamp with a reflective surface on the bottom to reduce the direct radiation,
It is not possible to reduce reflected glare more, and ordinary lamps cannot achieve that purpose. Furthermore, in this conventional example, when the angle of the lamp is raised toward the work surface, that is, when it is lifted forward, reflective glare occurs.

When the height H was 400 mm and the height was below the eye level of the worker M (eye line, indicated by EL in the figure), light distribution characteristics and illuminance distributions as shown in FIGS. 7 to 9 were obtained. desk 12
When the size is 700 x 1000 (mm) and the lamp 1 is set on the left end of the desk 12, the necessary and sufficient illuminance will be obtained in the work area of the desk 12, and the light beam will be wide from the left end light source toward the right end. It was found that the illuminance gradually decreased toward the right end.

は、ダークグレーマツト塗装が施される。 FIG. 14 shows an example of attaching the louver 20. Each louver piece 21 of the louver 20 becomes substantially parallel to the light irradiation direction. These louver pieces 21 are attached to a U-shaped rod 22, and both ends of the rod 22 are inserted into holes (not shown) in the lamp 1, and the base ends are provided in the end cap 4b of the lamp 1, etc. Lock it in a locking part (not shown). When such a louver 20 is provided, the brightness of the irradiated light beam in the direction of arrow Z in FIG. 15 is reduced. Therefore, OA in the direction of this arrow Z
(Office Automation) When the display 30 of the device is installed, the keyboard 40 placed at hand will be brightly illuminated by the irradiation light beams L 1 , L 2 , and L 3 as shown in FIGS. 16 and 17, and the display will be displayed. It is possible to let the reflection from 30 escape to the side instead of to the worker M side. In other words, due to the presence of the louver 20, the vertical illuminance on the screen of the display 30 is limited. The louver piece 21 is painted with dark gray matt.

２０を設けないものを示す。 The range of reflection on the screen of the display 30 is horizontal, as shown in Figures 18 and 19.
It has been found that the light has an irradiation direction of 45° to 80°, and 70° to 80° vertically. It has also been found that even if light outside this range hits the screen, the reflected light does not enter the eyes of the worker M. Therefore, louver pieces 21 are provided on the lower surface of the lamp 2 at predetermined intervals so as to be substantially parallel to the irradiation direction of the lamp 1. For more details,
The louver piece 21 is provided so as to be parallel to the screen of the display 30. The cross-hatched area in FIGS. 20 and 21 is the reflection range.
By installing the louver 20, the brightness of this reflected area can be increased to 500 cd/m 2 as shown in Fig. 22.
I was able to keep it below. FIG. 23 shows one without the louver 20.
