Where the arc range of the arc 311 is optimally 15rad, i.e. the arc 311 is approximately r15, the angle of the angle a is optimally 8 ° and the angle C of the arc 311 is optimally 104 °. The length range of the inclined part 312 is 30 +/-3 mm, the optimal value is 30mm, and after the special optimization design, light can be sufficiently reflected to a desktop which is 500mm away, so that the optimal reading illumination effect is realized.

Further, in the present embodiment, in order to improve the surface diffuse reflection performance of the reflector 300, the reflective surface 310 is covered with a white paint layer, and the surface diffuse reflection rate of the white paint layer is in a range of 80% ± 2.

In other words, at the two ends of the housing 100 along the width direction, the portion of the housing 100 below the diffusion plate 400 can perform a light shielding function, and when the portion is in the angle range of the included angle D, the eyes of the user sitting on the desk lamp on one side cannot see the light emitting element 200 on the other side, i.e., the light shielding angle of the eyes to the light emitting element 200 on the other side can be realized, so that the lamp has an anti-glare function. In addition, referring to fig. 1 and 3, in the present embodiment, since both ends of the housing 100 along the length direction are open, the desk lamp further includes a side cover 700 adapted to cover both ends of the housing 100 in consideration of beauty and preventing dust from entering the interior of the housing 100.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
