[0035] Reference Figures 1 to 3 In an embodiment of the utility model, a lighting unit capable of preventing and controlling excessive growth of the eye axis includes a box body 100, the box body 100 includes an upper plate 104 and a frame, the frame is located at the outer periphery of the workbench, and is surrounded by a lighting area 101 for installing a light source 110, a mounting seat 102 is provided in the lighting area 101, and a detachably mounted rod body 103 is plugged into the mounting seat 102, that is, the lighting area 101 is covered by the outer periphery of the mounting seat 102. It can be understood that in the projection along the vertical direction, the mounting seat 102 is embedded in the lighting area 101, and the lighting area 101 is at least covered by three side walls of the outer periphery of the mounting seat 102, which can increase the area of ​​the lighting area 101 while achieving fixed installation, which helps to improve the utilization rate of the lighting area of ​​the lamp body, thereby improving the lighting range.

[0036] It can be understood that the light source 110 includes a lamp board 113 and a plurality of lamp beads 111 laid on the lamp board 113. The emission spectrum of the lamp beads 111 is a continuous spectrum of 360nm - 800nm, which can effectively inhibit the excessive growth of the eye axis, that is, prevent and slow down the incidence of myopia. Further, the energy distribution composition of the continuous spectrum includes: 360nm - 400nm, 400nm - 480nm, 480nm - 640nm, 640m - 720nm, 720nm - 755nm, 755nm - 780nm, and 780nm - 800nm.

[0037] It can be understood that a lens 112 is provided on the lamp bead 111. A channel 117 for accommodating the lamp bead 111 is provided inside the lens 112. The lamp bead 111 is embedded in the lens 112. The light emitted by the lamp bead 111 enters the lens 112 from the inner wall of the channel 117 and is refracted through the outer wall surface of the lens 112 to produce a scattering effect. It can be understood that the lens 112 is fixedly installed on the lamp board 113. A concave portion 114 is provided on the rotation center of the lens 112. Continuous arc surfaces 116 are provided around the concave portion 114. Along the thickness direction of the lens 112, the lamp bead 111 corresponds to the position of the concave portion 114, which can increase the scattering range of the light, thereby avoiding the brightness of the lamp bead 111 being concentrated in the middle of the lens 112 to form a glare effect, helping to avoid visual fatigue and reducing the incidence of myopia. At the same time, a diffusion plate 118 is also provided on the box body 100. The light emitted by the light source 110 is irradiated to the outside through the diffusion plate 118, further increasing the scattering rate of the light, thereby improving the softness of the light and reducing the occurrence of visual fatigue.

[0038] It can be understood that the lens 112 is set as a disc shape, and the concave portion 114 is located on the central axis of the lens 112. Refer to Figure 3 , in the cross-section of the lens 112, there is a continuous arc 115 extending from the concave portion 114 to its radial outer edge. Along the radial direction of the lens 112, the arc 115 is symmetrically arranged on both sides of the concave portion 114. The middle part of the arc 115 has a protruding part extending away from the lamp board 113. When the arc 115 rotates one week around the central axis of the lens 112, the arc surface 116 around the concave portion 114 can be formed. Further, the arc 115 can be set as a curve with a fixed curvature, or can be set as a curve with a uniformly increasing or decreasing curvature. In some embodiments, the concave portion 114 is located at the intersection of the two arcs 115 and can be set as a sharp angle; in other embodiments, the concave portion 114 can be provided with an arc. Along the radial direction of the lens 112, the outer edge of the arc is tangent to the arc surface 116 to form a continuous curved surface, which helps to increase the scattering range and angle of the light, thereby improving the softness of the light irradiation, avoiding glare, and effectively reducing visual fatigue.

[0039] It can be understood that the minimum distance between the inner wall of the concave portion 114 and the lamp board 113 is D1, and the minimum distance between one end of the arc surface 116 located at the radial edge of the lens 112 and the lamp board 113 is D2. Requirements: D1 > D2, that is, the range of the arc surface 116 facing the radial outside of the lens 112 is larger than the range facing the inside, so that after the light emitted by the lamp beads 111 passes through the lens 112, it can be scattered more towards the radial periphery of the lens 112, which helps to ensure the lighting range and brightness while achieving the effect of reducing glare through the concave portion 114.

[0040] Referring to Figure 8 , a fixing edge 106 extending towards the light source 110 is provided on the inner wall of the frame 105, and the lamp board 113 is fixedly connected to the fixing edge 106 to realize the fixed installation of the lamp board 113 inside the box body 100. Further, a reinforcing plate 109 is provided on the side of the lamp board 113 facing away from the lamp beads 111, and a number of reinforcing ribs 1091 are provided on the reinforcing plate 109. The reinforcing plate 109 is fixedly installed on the lamp board 113. By providing the reinforcing ribs 1091, it helps to improve the structural rigidity of the lamp board 113 and avoid deformation. Further, referring to Figure 5 and Figure 7 , a supporting portion 1092 abutting against the upper plate 104 is provided on the reinforcing plate 109, which can keep a distance between the upper plate 104 and the lamp board 113 and avoid large-amplitude deformation of the upper plate 104.

[0041] Referring to Figure 4 , an upper plate 104 and a backlight lamp 107 are provided on the side of the box body 100 facing away from the rod body 103. The backlight lamp 107 is fixed to the inner side of the upper plate 104. It can be understood that the backlight lamp 107 emits light towards the side of the box body 100 away from the lighting area 101, which can increase the effect of indoor lighting, reduce the area with insufficient indoor light, and can improve the aesthetic degree by emitting light of different colors through the backlight lamp 107. Further, an installation plate 108 for installing the backlight lamp 107 is provided inside the box body 100. The installation plate 108 is fixedly connected to the upper plate 104, and there is a gap between the installation plate 108 and the lamp board 113, which can avoid mutual extrusion between the lamp board 113 and the installation plate 108 during transportation or handling, resulting in deformation.

[0042] According to an embodiment of the second aspect of the present invention, a floor lamp is provided, including the above-mentioned lighting unit capable of preventing and controlling excessive growth of the eye axis. It can be understood that the floor lamp includes all the technical features of a lighting unit capable of preventing and controlling excessive growth of the eye axis.
