[0029] A LED classroom eye protection lamp, such as Figure 1 and Figure 2 As shown, it includes a lamp panel 1, a diffusion plate 2, a light source (not shown in the figure), a lamp holder 3, a suspension rod 4 and a light-transmitting portion 5;

[0030] The light source is installed in the lamp panel 1, the diffusion plate 2 is covered at the opening of the lamp panel 1, the lamp holder 3 is arranged on the lamp panel 1, and the suspension rod 4 is fixedly connected to the lamp holder 3;

[0031] The light-transmitting part 5 includes a light-transmitting hole 51 and a bottom cover 52. The light-transmitting hole 51 passes through the bottom wall of the lamp panel 1. The bottom cover 52 is disposed on the light-transmitting hole 51 and is located on a side of the light-transmitting hole 51 away from the light source. The bottom cover 52 is made of light-transmitting material.

[0032] The utility model provides a light-transmitting portion 5 so that the classroom lamp can emit light from the back while ensuring the front light, thereby compensating for the brightness of the top surface of the traditional classroom lamp, making the lighting brightness distribution more uniform, and achieving the effect of seeing the light but not the lamp as a whole, thereby improving the lighting; the structure is simple and stable, meets the requirements of installation regulations, and has a wider applicability

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the diffuser plate 2 and the outer edge of the lamp panel 1 are matched with an outer frame 6 to fix the diffuser plate 2 on the lamp panel 1; a plurality of heat dissipation holes 7 are evenly distributed on the lamp panel 1; the lamp holder 3 and the lamp panel 1, the suspension rod 4 and the lamp holder 3 are all threadedly connected; the bottom cover 52 is designed in a bowl shape.

[0034] Specifically, Figure 2 As shown, there are two light-transmitting holes 51 and two bottom covers 52, and the light-transmitting portion 5 also includes a bottom plate 53 fixedly connected to the two bottom covers 52. The bottom plate 53 is arranged between the two bottom covers 52, and the bottom plate 53 and the two bottom covers 52 are designed as an integral molding. The arrangement of the double light-transmitting holes 51 and the double bottom covers 52 can make the top of the lamp emit light to both sides in a targeted manner, and the bottom plate 53 for connection is arranged to facilitate the installation and removal of the bottom covers 52. In this embodiment, the light-transmitting portion 5 is arranged at one end of the lamp panel 1. In addition, more than two light-transmitting holes 51 can be arranged according to actual needs.

[0035] Further, such as Figure 1 As shown, two light-transmitting parts 5 are provided, and are respectively provided at the two ends of the lamp panel 1, so as to further adjust the light-emitting angle of the top of the lamp. In addition, multiple light-transmitting parts 5 can be provided according to actual needs.

[0036] Further, such as Figure 1 As shown, two lamp stands 3 and two suspension rods 4 are provided, and the lamp stands 3 are mounted on the light-transmitting portion 5, so that the lamp can be more firmly installed in the effective area, reducing the risk of the lamp falling off.

[0037] Specifically, the diffusion plate 2 includes a diffusion structure and a prism structure which are stacked. The prism structure is arranged on a side of the diffusion structure away from the light source. The diffusion structure and the prism structure are integrally formed.

[0038] In actual application, the diffuser plate 2 is an integrated diffuser structure and prism structure, which has an anti-glare effect while ensuring the light output angle of the classroom lamp. The human eye can look directly at the light output surface of the lamp, reducing the stimulation of the light to the user and reducing visual fatigue.

[0039] Furthermore, the glare value UGR of the diffuser plate 2 is 16-19, which meets the standard and avoids the user from feeling disgusted or uncomfortable due to glare.

[0040] Furthermore, the up and down luminous flux ratio of the LED classroom eye protection lamp is 1:4 or 1:3.

[0041] Specifically, the lamp panel 1 is made of metal material, and the bottom cover 52 is made of polycarbonate. In this embodiment, the lamp panel 1 is a metal iron panel, and the bottom cover 52 is a polycarbonate light-transmitting cover, which has a stable and firm structure.

[0042] Further, such as Figure 1 As shown, a driving power source 8 is also provided on the back of the lamp panel 1, and the driving power source 8 is electrically connected to the light source.

[0043] Further, such as Figure 1 and Figure 2 As shown, the lamp panel 1 is also provided with longitudinal reinforcing ribs 9 and transverse reinforcing ribs 10. A plurality of longitudinal reinforcing ribs 9 and transverse reinforcing ribs 10 are provided, staggeredly distributed on the lamp panel 1, which can increase the strength and rigidity of the lamp panel 1 and prevent the lamp panel 1 from deforming.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
