Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] Combination Figures 1 to 11As shown, this embodiment provides a polarizing grid desktop lamp, including a base 1, a lamp post 2 connected to the base 1, and a lamp body 3 connected to the lamp post 2; the lamp body 3 includes a lower light source for downward light emission and a light emitting element 4 adapted to the lower light source; the light emitting element 4 includes a first diffuser plate 5, the first diffuser plate 5 including a light-incident surface and a light-emitting surface; a plurality of grids 6 with specific tilt angles are arranged at intervals on the light-emitting surface, and light-emitting channels 7 with specific tilt angles are formed between the grids 6.

[0031] In this embodiment, as Figure 5 , Figure 6 and Figure 8 and Figure 9 As shown, the lamp body 3 includes a heat sink 8, with a first mounting cavity 9 having a flared opening at its center; the lower light source is located at the bottom of the first mounting cavity 9; the light emitting component 4 is located near the lower opening and has a certain distance from the lower light source. The lower light source refers to a lighting unit that emits light downwards and is installed at the bottom of the first mounting cavity 9. It has LED beads and a lower light source board 10, and is powered and controlled by a circuit board. The diffuser plate is used to diffuse the light emitted by the lighting unit from the light-incident surface to the light-emitting surface, making the light on the light-emitting surface softer and reducing glare. The arrangement of multiple grilles 6 with specific tilt angles forms a light-emitting channel 7 with specific tilt angles. In this embodiment, the tilt angle is set to 75 degrees forward (i.e., the side opposite to the lamp post 2), which only allows light from a specific direction to pass through, filtering light from a specific direction and blocking more than 99% of reflected glare; at the same time, it can project the light further, improve the uniformity of illumination in a certain area, achieve the effect of light from a distance, and provide people with better light comfort. In other words, this solution uses a diffuser plate to diffuse the light and a grid structure (6) to define the light angle, making the light soft and focused on the target area. This combined structure achieves both directional lighting and glare suppression while maintaining the softness of the light.

[0032] In this embodiment, the first mounting cavity 9 is arranged through the entire length direction, so the heat sink 8 can be directly cut from a profile, which is convenient, quick, and low-cost. A first slot 11 is provided on the bottom side wall of the first mounting cavity 9 for limiting the lower light source plate 10; the lower light source plate 10 can be directly inserted into the first slot 11 from the openings at both ends, thus eliminating the need for additional screws to fix the lower light source plate 10 to the heat sink 8. A second slot 12 is provided on the side wall near the lower opening for limiting the light emitting element 4; similarly, the light emitting element 4 does not require screws for fixation. End caps 13 are provided at both ends of the heat sink 8 to limit the length of the lower light source plate 10 and the light emitting element 4. In this embodiment, the light-emitting element 4 is positioned close to the lower opening and has a certain distance from the lower light source. This prevents the heat from the light source from being directly conducted to the light-emitting element 4, thereby preventing heat accumulation that could cause deformation of the optical element. At the same time, it also allows the light emitted by each LED bead to hit the light-incident surface more evenly and comprehensively, reducing local strong light phenomena and thus forming a more uniform light spot when the light diffuses downward.

[0033] In this embodiment, as Figure 7 , Figure 10 and Figure 11 As shown, a second mounting cavity 14 is provided inside the first mounting cavity 9, that is, on the side near the lamp post 2; a third slot 15 is provided on the upper side of the second mounting cavity 14 for mounting the upper light source assembly; a light outlet 16 is provided on the upper end face of the second mounting cavity 14; a second diffuser plate 17 is provided on the light outlet 16. Specifically, it includes an upper light source bracket 18, which is also cut from a metal profile and has a third mounting cavity 19 with an upper opening; a first outwardly protruding latching part 20 is provided on the side wall of the upper opening end of the upper light source bracket 18, which latches onto the third slot 15, and a second inwardly protruding latching part 21 forms a fourth slot 22 with the bottom wall of the second mounting cavity 14 for latching the second diffuser plate 17; a fifth slot 23 is provided at the bottom of the third mounting cavity 19 for latching the upper light source plate 24.

[0034] The top light source supplements the lighting in the upper space, solving the problem of dimness in the top area caused by a single downward light source. It achieves coordinated lighting in both the upper and lower areas of the floor lamp. In reading or working scenarios, the top light source can supplement the ambient light to reduce the contrast between light and dark, thereby improving the comfort of local lighting.

[0035] The third slot 15, the fourth slot 22 and the fifth slot 23 are provided so that the upper light source bracket 18, the second diffuser plate 17 and the upper light source plate 24 can be directly inserted through the openings at both ends, which makes the installation convenient and quick and reduces the installation cost.

[0036] Furthermore, the bottom wall of the third mounting cavity 19 of the upper light source bracket 18 is inclined so that the light from the upper light source is directed towards the lamp post 2. That is, the lower light source shines forward and downward, while the upper light source shines upward and backward. The diffuse reflection of the light from the upper light source hitting the ceiling provides supplementary lighting to the surrounding area, solving the problem of insufficient lighting in the upper space of traditional floor lamps.

[0037] Of course, it should be noted that the polarized grid desktop light also includes a control motherboard, driver components, and control panel, which are existing technologies and will not be described in detail here.
