Since the lighting device is arranged at a position below the user's eye level, it is especially suitable for table lighting, especially for the lighting situation with a display on the table. The lighting device only illuminates the position below the display in the working state, does not affect the display of the display, prevents the user from looking directly at the light source, and also does not cause bad experiences such as glare.

On the other hand, through the concave arrangement of the inscribed surface, especially through the arrangement of the first sloped surface 311, the second sloped surface 312 and the third sloped surface 313, the substantially linear light-emitting unit 2 can illuminate most of the area, while having a relatively large area. Good uniformity effect.

Without the use of the lens 3 of the present invention, the linear light-emitting unit 2 parallel to the edge of the desktop can only illuminate the desktop with a depth of about 20 cm, and only the illumination area in the direct direction of the light-emitting unit 2 has better illumination The brightness of the illumination area adjacent to the light-emitting unit 2 decreases rapidly.

Due to the limited area of the desktop, the size and size of the light sources that can be arranged in the desktop lighting are also limited. If it is too small, the brightness of the illumination on both sides will decay rapidly, so it is a better solution to use a linear light source. However, the linear light source has the above-mentioned problem of uneven illumination in the depth direction. The problem of uneven illumination in the depth direction can be better solved.
