Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to an eye protection lamp. Background Art

[0002] In traditional lamps, the light source is small in size, but to meet the lighting needs, the light source must be bright and the light emitted is relatively glaring. To improve the lighting comfort, people use light guide plates to expand the light source's luminous area, so that the light emitted by the light source is evenly dispersed onto the larger light guide plate. The light guide plate then provides lighting, making the light softer and more comfortable.

[0003] Currently reported lamps, such as Patent 201420663534.8 for a flat panel lamp and Patent CN201821693885.8 for an optical component and panel lamp, lack 360-degree spatial coverage. Furthermore, their light sources have limited adjustability, making them inadequate for diverse scenarios such as learning, nighttime, and daytime lighting. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an eye protection lamp with a simple structure, which can achieve 360-degree spatial coverage of the light source and can be used in multiple life scenarios.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] An eye protection lamp includes a lower frame and an upper frame buckled onto the lower frame, a lamp cavity being formed between the lower frame and the upper frame, a first heat sink being installed in the lamp cavity, a diffuser plate, a light guide plate, and reflective paper being stacked in sequence from bottom to top between the first heat sink and the lower frame, a first LED light bar and an LED light panel strip being surrounded by the diffuser plate, the light guide plate, and the reflective paper, and light-emitting surfaces of the first LED light bar and the LED light panel strip facing the diffuser plate, the light guide plate, and the reflective paper;

[0007] A second heat sink is installed in the lamp cavity, an LED light board is installed between the second heat sink and the upper frame, and the light-emitting surface of the LED light board faces the upper frame.

[0008] This eye protection lamp is equipped with a first LED light bar, an LED light panel, and an LED light panel. Light from the first LED light bar and LED light panel enters from the side of a light guide plate, refracts the light, and is reflected downward by reflective paper before being atomized and diffused by a diffuser plate. In other words, light from the first LED light bar and LED light panel ultimately exits through the diffuser plate below. Light from the LED light panel exits directly from the diffuser cover above, achieving 360-degree spatial coverage.

[0009] In addition, in this design, the first LED light strip, LED light panel strip and LED light panel are equipped with independent control systems. Therefore, the first LED light strip, LED light panel strip and LED light panel can adjust their color temperature individually to meet the use of multiple life scenarios.

[0010] For example, in study mode, light with a color temperature range of 4000K to 5000K is generally used. This color temperature range is relatively soft and close to natural light. Natural daylight provides a comfortable visual experience, and a 4000K to 5000K eye-protection lamp brings the benefits of natural light indoors. This color temperature can effectively reduce eye fatigue, especially during prolonged reading and writing. If the color temperature is too high, the light will be cool white or bluish-white, which can cause dryness and fatigue in the eyes. If the color temperature is too low, the light will be yellowish, which can easily cause drowsiness and hinder concentration on study and work.

[0011] For example: Working mode: The color temperature is approximately 4500K - 5500K. This cool white light can help people focus and is more suitable for office environments or when performing fine manual work. The light intensity is strong and can illuminate work areas such as desks and workbenches.

[0012] For example, in sleep mode, the brightness is very low, and the light emitted is very weak, usually with a warm color, such as a warm yellow light around 2700K. It is mainly used for nighttime lighting to facilitate people getting up at night. It can provide enough light to see the surrounding environment clearly without irritating the eyes and making it difficult to fall asleep again.

[0013] For example, Party Mode offers a richer range of lighting colors, typically in full RGB. Adjustable lighting can create a variety of color changes or dynamic flashing effects. This creates a cheerful and lively atmosphere, making it suitable for family gatherings, parties, and other occasions, adding to the fun.

[0014] Furthermore, a first baffle is extended from the edge of the first heat sink toward the lower frame, and the diffuser, light guide plate and reflective paper are arranged in a first accommodating cavity formed by the first heat sink and the first baffle, and the first LED light strip and the LED light panel strip are closely attached to the inner side of the first baffle.

[0015] The overall shape of the eye protection lamp can be circular, square or other shapes. Therefore, the first heat dissipation plate and the first accommodating cavity formed by the first heat dissipation plate and the first baffle can also be circular, square or other shapes accordingly.

[0016] Furthermore, when the first heat sink is rectangular, there is one first LED light bar, and there are three LED light panel strips arranged in a U shape. When the first heat sink is circular, there is one first LED light bar, and there is one LED light panel strip, and the first LED light bar and the LED light panel strips are arranged in a circular shape.

[0017] Furthermore, a circle of adhesive strips is provided between the reflective paper and the first heat sink to hold down the edges of the reflective paper. The main purpose of this design is to use the adhesive strips to hold down the stacked diffuser plate, light guide plate, and reflective paper, preventing them from shaking within the first accommodating cavity.

[0018] Furthermore, the first baffle is provided with a first mounting protrusion, through which a first screw passes and is screwed into the lower frame. The edge of the lower lamp hole in the lower frame is provided with a positioning groove for placing the diffuser plate. This design is primarily intended to facilitate assembly. The stacked diffuser plate, light guide plate, and reflective paper are positioned along the positioning grooves, and then the reflective paper is pressed with a rubber strip. The first heat sink is then secured to the lower frame with the first screw to complete the installation. The rubber strip not only compresses the reflective paper but also provides a cushioning force for securing the first heat sink plate.

[0019] Furthermore, a second baffle is extended from the edge of the second heat sink toward the upper frame, and the LED light board is arranged in a second accommodating cavity formed by the second heat sink and the second baffle, and the LED light board is closely attached to the second heat sink.

[0020] Furthermore, a through hole is provided at the center of the first heat dissipation plate, and the second heat dissipation plate is installed in the through hole.

[0021] Furthermore, the second baffle is provided with a second mounting protrusion, and the second screw passes through the second mounting protrusion and is screwed into the first heat dissipation plate.

[0022] Furthermore, the second heat dissipation plate is covered with a diffusion cover, and the top surface of the diffusion cover extends out of the upper lamp hole of the upper frame.

[0023] Furthermore, the eye protection lamp also includes a floor lamp stand, which is a hollow square vertical pole for easy wiring. The top of the floor lamp stand is installed on the bottom of the lower frame, and the bottom of the floor lamp stand is installed with a U-shaped piece for easy standing. An adjustment button is also installed in the middle of the floor lamp stand.

[0024] It is understood that the shape of the floor lamp stand can be a hollow square pole, a hollow round pole, or other pole shapes designed for aesthetics. In addition, the adjustment button is used to adjust the brightness of the first LED light strip, the LED light panel strip, and the LED light panel, making the light brighter or darker to meet the lighting needs of different environments, such as brightening it for reading and dimming it for resting. Adjust the color temperature to change the color of the light. Low color temperature light tends to be warm yellow, giving people a warm feeling; high color temperature light tends to be cool white, appearing brighter and clearer.

[0025] Furthermore, an upper connecting piece is installed inside the top end of the floor lamp stand, and a lower connecting piece is installed inside the bottom end of the floor lamp stand. The floor lamp stand is installed on the bottom surface of the lower frame through the upper connecting piece, and the U-shaped piece is installed on the floor lamp stand through the lower connecting piece.

[0026] Furthermore, a 48-volt power converter is installed inside the floor lamp stand.

[0027] Furthermore, a speaker is installed on the floor lamp stand.

[0028] The utility model has the following advantages over the prior art:

[0029] 1. This eye protection lamp is equipped with a first LED light bar, an LED light panel, and an LED light panel. Light from the first LED light bar and LED light panel enters from the side of a light guide plate, refracts the light, and the reflective paper reflects the light downward. Finally, it is atomized and diffused by a diffuser plate. In other words, light from the first LED light bar and LED light panel ultimately exits through the diffuser plate below. Light from the LED light panel exits directly through the diffuser cover above, achieving 360-degree spatial coverage.

[0030] 2. In this design, the first LED light strip, LED light strip and LED light board are equipped with independent control systems. Therefore, the first LED light strip, LED light strip and LED light board can adjust the color temperature separately to meet the use of multiple life scenarios.

[0031] 3. This design includes a first heat sink and a second heat sink, which respectively dissipate heat for the first LED light strip, the LED light board strip and the LED light board, ensuring the durability of the eye protection lamp.

[0032] 4. This design's first LED light bar, LED light panel, and LED light panel offer zero harmful blue light, protecting your eyes and effectively blocking radiation and eye irritation. Zero visible flicker creates a stable, high-quality light source, alleviating children's visual fatigue. The light is closer to the flicker-free state of sunlight, preventing visual fatigue from prolonged use. Zero glare is present, thanks to the full spectrum of the Puri light, ensuring direct viewing without fear of glare. With a UGR ≤ 17 anti-glare rating and five layers of soft light, even direct viewing is possible.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The eye protection lamp 1 shown includes a lower frame 11 and an upper frame 12 that is buckled onto the lower frame 11. A lamp cavity 16 is formed between the lower frame 11 and the upper frame 12. A first heat sink 5 is installed in the lamp cavity 16. A diffuser plate 13, a light guide plate 14, and reflective paper 15 are stacked in sequence from bottom to top between the first heat sink 5 and the lower frame 11. A first LED light bar 3 and an LED light panel strip 4 are surrounded by the diffuser plate 13, the light guide plate 14, and the reflective paper 15, and the light-emitting surfaces of the first LED light bar 3 and the LED light panel strip 4 face the diffuser plate 13, the light guide plate 14, and the reflective paper 15.

[0042] A second heat sink 6 is installed in the lamp cavity 16 , and an LED lamp board 7 is installed between the second heat sink 6 and the upper frame 12 , with the light-emitting surface of the LED lamp board 7 facing the upper frame 12 .

[0043] This eye protection lamp is equipped with a first LED light bar 3, an LED light panel strip 4, and an LED light panel 7. Light from the first LED light bar 3 and LED light panel strip 4 enters from the side of a light guide plate 14, refracts the light, and is reflected downward by reflective paper 15 before being atomized and diffused by a diffuser plate 13. In other words, light from the first LED light bar 3 and LED light panel strip 4 ultimately exits through the diffuser plate 13 below. Light from the LED light panel 7 exits directly from the diffuser cover 8 above, achieving 360-degree spatial coverage.

[0044] In addition, in this design, the first LED light strip 3, LED light panel strip 4 and LED light panel 7 are equipped with independent control systems. Therefore, the first LED light strip 3, LED light panel strip 4 and LED light panel 7 can adjust their color temperature individually to meet the use of multiple life scenarios.

[0046] For example: Learning mode: generally use light in the color temperature range of 4000K - 5000K, which is relatively soft and close to natural light. The visual experience is more comfortable under natural light during the day, and the 4000K - 5000K eye protection lamp is like moving the advantages of natural light indoors. Such a color temperature can effectively reduce eye fatigue, especially in eye-using scenarios such as long-term reading and writing. If the color temperature is too high, the light is cold white or bluish white, which can easily make the eyes feel dry and tired; and if the color temperature is too low, the light is yellowish, which can easily make people sleepy and is not conducive to concentrating on learning and working. In this embodiment, the first LED light strip 3, the LED light panel strip 4 and the LED light panel 7 are all turned on, or the first LED light strip 3 and the LED light panel strip 4 are turned on.

[0047] For example, in working mode, the color temperature is approximately 4500K-5500K. This cool white light helps people focus and is suitable for office environments or delicate manual work. The light intensity is strong enough to illuminate work areas such as desks and workbenches. In this embodiment, the first LED light strip 3, LED light panel strip 4, and LED light panel 7 are all turned on.

[0048] For example, in sleep mode, the brightness is very low, with a very faint light, typically a warm color, such as a warm yellow light around 2700K. This is primarily used for nighttime illumination, making it easier for people to wake up during sleep. It provides enough light to see the surroundings without irritating the eyes and making it difficult to fall asleep again. In this embodiment, the LED light strip 4 is turned on.

[0049] For example, Party Mode: This mode features a richer range of lighting colors, typically full RGB color. Adjustable color variations and dynamic flashing effects can be achieved. This creates a cheerful and lively atmosphere, making it suitable for family gatherings, parties, and other occasions, adding to the fun. In this embodiment, the first LED light strip 3, LED light panel strip 4, and LED light panel 7 are implemented using chips mounted within the lamp body.
