[0002] Eye-protection lighting fixtures are lighting devices that reduce eye fatigue and potential damage by optimizing light source characteristics (such as spectrum, flicker, glare, etc.). Their core technologies include simulating the natural light spectrum (full-spectrum technology), eliminating flicker, and reducing blue light hazards, aiming to provide a lighting environment that is closer to natural light. Eye-protection lighting fixtures are suitable for various scenarios, including study and office settings, home living settings, and settings for special groups of people.

Fluorescent lamps, halogen lamps, and incandescent lamps have low energy efficiency and generate a lot of heat, so there is a need for a red light eye-protection device and design method with better eye protection effect.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, 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 protection scope of this utility model.

[0044] The preferred embodiment of the red light eye protection device of this utility model, such as Figure 1 As shown, see also Figures 2-13 It includes a first light source, a second light source, a third light source, a fourth light source, and a fifth light source. The first light source emits white light, while the second, third, fourth, and fifth light sources emit red light. The wavelengths of the second, third, fourth, and fifth light sources increase sequentially. The mixed light from the second, third, fourth, and fifth light sources is used to supplement the first light source's lack of red light in the 630nm-800nm ​​band.

[0045] This application utilizes LED white light to supplement the 630nm-800nm ​​wavelength spectrum, forming a full and continuous spectrum to achieve an eye-protecting effect, thereby solving the eye protection problem.

[0046] The specific implementation structure can be:

[0047] The first light source includes multiple LED beads 1; the device also includes a light guide plate 2, with multiple LED beads 1 distributed on the side of the light guide plate 2, and one side surface of the light guide plate 2 is the light-emitting surface; the device also includes a light source plate 3, with the second, third, fourth and fifth light sources all disposed on the light source plate 3, and a light-emitting hole is opened in the middle of the light guide plate 2, which is directly opposite to the light source plate 3, and a light-diffusing mask 4 is disposed at the light-emitting hole;

[0048] The light emitted by LED bead 1 is directed towards the light guide plate. One side of the light guide plate 2 has a laser-dotted microstructure, and the other side is a smooth and transparent surface. Part of the light entering the light guide plate 2 undergoes total internal reflection inside the light guide plate 2, while the other part is transmitted through the dots at the bottom of the light guide plate 2 and then incident on the diffuse reflective paper, where a Lambertian reflection is formed. The reflected light passes through the light guide plate 2 again and is incident on the diffusion film on the light guide plate 2, forming diffused light. The light on the diffusion film is refracted through the outermost prism plate 5, thus forming surface light emission.

[0049] It should be noted that the aforementioned diffuse reflection paper and prism plate are not essential light processing structures and can be replaced by other existing structures. It is only necessary to further homogenize the light from the light guide plate.

[0050] Preferably, the second, third, fourth, and fifth light sources are evenly arranged on the square light source plate 3, and in front of the light source plate 3 is a light-diffusing mask 6 (semi-transparent frosted mask) with a beaded inner surface, from which the light emitted by the second, third, fourth, and fifth light sources is emitted.

[0051] in:

[0052] The color temperature range of the first light source is 2700K-6500K;

[0053] The wavelength range of the second light source is 615-645nm;

[0054] The wavelength range of the third light source is 685-715nm;

[0055] The wavelength range of the fourth light source is 715-745nm;

[0056] The wavelength range of the fifth light source is 745-765nm;

[0057] The ratio of the number of LEDs in the second, third, fourth, and fifth light sources is 4:10:13:15;

[0058] The power ratios of the first, second, third, fourth, and fifth light sources are 50:0.8:2:2.6:3 or 50:1.2:3:3.9:4.5.

[0064] like Figure 7 As shown, the wavelength of the fourth light source is 730nm;

[0065] like Figure 8As shown, the wavelength of the fifth light source is 760nm;

[0066] The power ratio of the first, second, third, fourth, and fifth light sources is 50:0.8:2:2.6:3;

[0067] like Figure 10 and Figure 11 As shown, in the 700-800nm ​​wavelength range, the red light is fully supplemented to above 0.4. Compared with the standard spectrum, the red light is well supplemented in the 630-800nm ​​wavelength range.

[0068] like Figure 12 and Figure 13 As shown, see also Figures 4-8 Another optional embodiment (basically the same as the previous embodiment, except for the power ratio of the five light sources):

[0069] The power ratio of the first, second, third, fourth, and fifth light sources is 50:1.2:3:3.9:4.5.

[0070] like Figure 12 and Figure 13 As shown, compared with the standard spectrum, in the wavelength range of 630-800nm, the red light is fuller and richer (0.6) than in Scheme 1, which is closer to the standard spectrum.

[0071] A design method for a red light eye protection device, based on the aforementioned red light eye protection device, wherein the method includes the following steps:

A light-emitting hole is opened in the center of the light guide plate, directly opposite the light source plate, and a light-diffusing mask is provided at the light-emitting hole.

[0073] The mixed light from the second, third, fourth, and fifth light sources is designed to compensate for the lack of the first light source in the 630nm-800nm ​​red light band, specifically including:

[0074] The color temperature range of the first light source is 2700K-6500K;
