[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following further describes a lamp with a wide illumination range of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Please refer to Figure 1-Figure 7 , a lamp with a high irradiation range, comprising:

[0033] LED lights 100;

[0034] The light emitting plate 200 is made of a translucent material. The LED lamp 100 shines on the light emitting plate 200. The light emitting plate 200 is provided with a plurality of prismatic protrusions 210. The side edges of the prismatic protrusions 210 include a short edge 211, a long edge 212 and a plurality of connecting edges 213 located between the short edge 211 and the long edge 212. The length of the connecting edge 213 increases successively from the short edge 211 to the long edge 212.

[0035] The light emitted by the LED lamp 100 passes through the light emitting plate 200, which is provided with a plurality of prism protrusions 210. The prism protrusions 210 have a special shape, and a plurality of prism slopes of different lengths and slopes are formed between the short prisms 211, the connecting prisms 213 and the long prisms 212. When the light 710 is irradiated on different prism slopes, different angles of refraction are generated. By controlling the setting direction of the prism protrusions 210, the light 710 can be refracted in different directions. The light 710 is refracted by different prism protrusions 210 to the left, forward and right, thereby increasing and brightening the illuminated area 700, making reading more convenient.

[0036] Please refer to Figure 4The prismatic protrusion 210 is in a pyramid shape. The pyramid shape makes each surface an inclined surface, without a horizontal surface, and the light 710 passing through the prismatic protrusion 210 will be refracted, thereby avoiding the situation where the light 710 is not refracted and causes the local area to be too bright.

[0037] Please refer to Figure 5 and Figure 6 The prismatic protrusion 210 is positioned facing the LED lamp 100. When the prismatic protrusion 210 faces the LED lamp 100, the light 710 is refracted at a larger angle on the inclined surfaces on either side of the short ribs 211 and at a smaller angle on either side of the long ribs 212. This causes the light 710 to spread toward the short ribs 211. Furthermore, due to the larger inclined surfaces on either side of the long ribs 212, more light is diffused, enhancing the brightness of the diffused area and ensuring uniform illumination. The surface of the light emitting plate 200 facing away from the LED lamp 100 is smooth, creating an aesthetically pleasing appearance. Similarly, when the prismatic protrusion 210 is positioned facing away from the LED lamp 100, the light 710 spreads toward the long ribs 212. This can be configured as needed.

[0038] Preferably, the prismatic protrusions 210 are symmetrical in structure. With a symmetrical structure, the light 710 is evenly diffused, and the resulting light is softer.

[0039] Please refer to Figure 3 and Figure 4 The prismatic protrusion 210 includes a short bevel 214 formed by two short edges 211, a long bevel 215 formed by two long edges 212, and a connecting bevel 216 disposed between the short bevel 214 and the long bevel 215. The bevel determines the diffusion direction, and the light is more uniform in the diffusion direction.

[0040] Please refer to Figure 3 As an embodiment of the present invention, the prismatic protrusion 210 faces the LED lamp 100, and the prismatic protrusions 210 form a left light expansion portion 220, a side light expansion portion 230, and a right light expansion portion 240 from left to right. The short ridges 211 of the prismatic protrusion 210 of the left light expansion portion 220 are located on the left side, the short ridges 211 of the prismatic protrusion 210 of the right light expansion portion 240 are located on the right side, and the short ridges 211 of the prismatic protrusion 210 of the side light expansion portion 230 are located on the front side. Please refer to Figure 7The illumination area 700 spreads to the left, right, and front. As another embodiment of the present invention, the prismatic protrusions 210 face away from the LED lamp 100. The prismatic protrusions 210 sequentially form a left light expansion portion 220, a side light expansion portion 230, and a right light expansion portion 240 from left to right. The long edge 212 of the prismatic protrusion 210 of the left light expansion portion 220 is located on the left side, the long edge 212 of the prismatic protrusion 210 of the right light expansion portion 240 is located on the right side, the long edge 212 of the prismatic protrusion 210 of the side light expansion portion 230 near the front side is located on the front side, and the long edge 212 of the prismatic protrusion 210 of the side light expansion portion 230 near the rear side is located on the rear side.

[0041] Please refer to Figure 1 、 Figure 5 and Figure 6 , further comprising a light diffusing plate 300, which is located on the side of the light emitting plate 200 facing the LED lamp 100. The light diffusing plate 300 diffuses the light to make it softer and less glaring, and the light 710 passing through the prism convex body has more angles, making the light more uniform and having a wider diffusion range.

[0042] Please refer to Figure 1 、 Figure 5 and Figure 6 , further comprising a top cover 400 and a bottom frame 500. The top cover 400 and bottom frame 500 are detachably connected. The top cover 400, LED lamp 100, light diffuser 300, light output panel 200, and bottom frame 500 are sequentially arranged. This means that they are fixed together by the top cover 400 and bottom frame 500, which is simple and convenient. The top cover 400 and bottom frame 500 are generally connected using snap-fit or screws.

[0043] Please refer to Figure 5 and Figure 6 The top cover 400 has a reflective coating or reflector 410 on the side facing the LED lamp 100. The reflective coating or reflector 410 can enhance brightness and improve light utilization efficiency. Some light 710 is reflected and directed downward, diffused by the light diffuser 300, and then refracted and emitted from the light output plate 200.

[0044] Please refer to Figure 1 , further comprising a base 600, the base 600 being connected to the top cover 400 and / or the bottom frame 500 via a folding bracket 610 or a flexible bracket. That is, a table lamp shape is formed, which can be more conveniently placed on a desktop. In particular, the base 600 can be clip-type as needed.

[0045] It is understandable that the shape of the light emitting plate 200 can be set as needed. For example, if a circular illumination range is required, it can be set to a circle; if an elliptical illumination range is required, it can be set to an elliptical or waist-shaped shape.

[0046] Please refer to Figure 8 , Figure 8This is a diagram of the refraction principle of the present invention. Assuming that the refractive index of the light output plate is n, the inclination angle of the long bevel is N, and the incident angle of the light is A, then n = sinA / sinB, C = NB, and n = sinD / sinC. From this, we can obtain sinD = nsinC = nsin(NB) = nsin(N-(arcsin[(sinA) / n])), that is, the larger the inclination angle N, the larger the refractive angle D, and the larger the refractive index n, the larger the inclination angle D. Based on this, the required refraction angle and light expansion range can be obtained as needed. Similarly, the same is true when the short bevel refracts. The area of light contacted by the short bevel is smaller, and the amount of light is lower. The refracted light is mainly used to reinforce the illumination area 700, making the illumination area 700 brighter and more uniform, and enhancing light utilization.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0048] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0049] In summary, the utility model provides a lamp with a high illumination range. The light emitted by the LED lamp passes through a light emitting plate. A plurality of prism protrusions are arranged on the light emitting plate. The prism protrusions adopt a special shape. A plurality of prism slopes with different lengths and slopes are formed between the short edges, connecting edges and long edges. When the light is irradiated on different prism slopes, different angles of refraction are generated. By controlling the setting direction of the prism protrusions, the light can be refracted in different directions. The light is refracted to the left, forward and right through different prism protrusions, thereby increasing and brightening the illumination area. The utility model has strong applicability, a wide illumination range, brightening without being dazzling, bringing visual satisfaction and comfort to users, reducing eye fatigue and visual fatigue symptoms during study or work, helping to provide concentration, reduce eye pressure, and effectively prevent myopia; more efficiently utilize energy, avoid excessive waste, and protect the environment.
