New description: [New technical field] This creation is related to the structure of the lamp, especially a lamp structure without the need to add a diffusing agent. [Prior Art] With the advancement of technology, various types of electrical products have been introduced, and people are increasingly relying on the use of electrical appliances. From the traditional crane light bulbs and fluorescent lamps, the service devices are constantly being updated. In recent years, Light Emitting LEDs have been rapidly developed due to their low power consumption, component life, and the need for inter-material, fast response, and volume. I would like to know the application of the light-emitting diode as the light source of the luminaire structure. The light-emitting diode is placed on the traditional printed circuit, and the circuit is connected, and the light-emitting diode is attached to the transparent substrate to make the self-luminous diode emit 2 = Paying a transparent substrate with a diffusing agent, and causing the light to become irregular. However, because the diffusing agent itself cannot penetrate the diffusing agent, the light diffusion caused by it is insufficient to help the light passing rate. In other words, the use of a diffusing agent is now known as the A-line, but the material is very clear. Attenuation =: This will cause the brightness of the conventional lamp structure to be insufficient, so that the product is high, ί: ι luminaire structure 'has uniform light distribution and brightness [new content] is the goal of the industry. And the hairpin structure includes a lamp cover, a diffusion film to cover the upper case and the lower case, the upper case defines a 3/10 M409361 opening, the lower case is made of a light transmissive material, and the lower case is adapted The upper housing and the lower housing together define an accommodation space. The illuminating device is accommodated in the accommodating space and is fixedly connected to the lamp cover. The diffusion film has a first surface and a second surface opposite to each other, the first surface is disposed toward the upper casing, and the first surface is convexly spaced apart to form a plurality of circular arc columns, and the second surface faces the lower shell The body is disposed and the second surface is a smooth surface. Wherein, the light is emitted from the light-emitting device, sequentially passes through the first surface, the second surface and the lower casing, and the light is evenly dispersed by causing light scattering through the plurality of circular arc cylinders. In summary, the present invention has the following beneficial effects: the light emitted from the self-illuminating device causes light to be scattered by passing through a plurality of arcuate cylinders arranged side by side and spaced apart. By this arrangement, the structure of the lamp can not only disperse the light evenly, but also achieve the anti-glare effect, and when the lamp structure is used, there is no longer a problem of uneven light and dark distribution and serious light decay. [Embodiment] This creation relates to a lamp structure, which will be explained below through several embodiments. The description of the embodiments is for illustrative purposes only and is not intended to be limiting. It should be noted that the dimensional relationship between the components in the drawings is only for easy understanding and not for limiting the actual ratio. 1 to 2 are respectively a perspective view and an exploded view of the first embodiment of the luminaire structure 1 of the present invention. The structure of the lamp 1 is mainly composed of the lamp cover 11, the diffusion film 13, and the light-emitting device 15. The structure of the lamp holder and the lamp holder can be arbitrarily changed by those skilled in the art, and is not limited herein. Referring to FIG. 1 and FIG. 2, the lampshade 11 has an upper casing 114 and a lower casing 4/10 M4.09361 U5. The upper casing 114 defines an opening 11 () made of material to allow light to pass through, = = == light. Thereby, the upper casing m and the lower casing 115 are combined with each other, and the illuminating device 15 is disposed in the accommodating space. . Furthermore, the diffusion film 13 has a relative confinement 132, and the first surface 131 is convex and spaced apart from the surface 131 and the second surface. The surface of the surface 132 is slid into a curved surface. - the surface m is disposed toward the upper casing 114, and the middle diffusing plate 13 is disposed in the accommodating space toward the lower casing 115 15 with respect to the second surface 115 of the first surface m. The '4 garments are arranged to pass through the first surface (3), the first: ^: emits light, which will scatter outside. However, the manufacturer can also change 32 and the lower body 115 to ^ 11C ^ JM to change the face of a younger brother 131 toward the lower distortion: two; the second surface 132 of the first surface 131 is toward the ί, two, the same type It is a well-known setting that is well known to those skilled in the art. Please refer to FIG. 3 and FIG. 4 together, the second embodiment of m 3 1 and the light-emitting device of the lamp structure of the present invention include a lamp cover 11, a diffusion film 13 and a diffusion film of the former example. The appearance shape is also like the expansion:: two: and it is different from the first embodiment, the second embodiment, the second, the Α perpendicular to the arc cylinder I3la axially f-fold, and the expansion of the diaphragm 13 axially bent along the arcuate cylinder 13Ia::: ΓΓ, the direction of the diffusion diaphragm 13 can be set, the user environment and the occasion are different, and the setting is changed. The diffusion film U is different from the fifth structure of the lamp structure 1, and the rest of the arrangement is not different from the previous embodiment, so it will not be described again at 5/1〇M409361. Please refer to FIG. 5 and FIG. 6 . More specifically, in the first embodiment and the second embodiment, each of the circular arc cylinders (3) a formed on the diffusion 13 has a rate radius of Π) to HK). Between the micrometers, and (4) each of the four cylinders ma has a first-width w. The first width wi is preferably between 1 and 5 micrometers; and the center of curvature of the adjacent arcuate cylinders uia The second width W2 of the second width W2 is preferably between 1 〇 and 200 μm. Further, each of the arcuate top surfaces of the arcuate cylinders i3ia is formed with a tangent plane 131b, and each of the tangent planes 131b has three widths W3'. The third width W3 is preferably between i and 5 〇 micro . The diffusion film 13 of the present lamp structure 1 is disposed by the first width W1 on the first surface 131 and the third width W3 on the circular arc body 131a, and is matched with the diffusion plate 13 and the light-emitting device. The preferred distance between the distances is between 5 and 20 mm. By the above arrangement, the convergence angle of the light travel is reduced, thereby reducing the light loss, compared to the lamp structure using a diffusing agent in the prior art. In other words, the brightness of the created lamp structure 1 can be greatly improved. However, it should be noted here that the definition of the above dimensions is only a better function of the structure of the present lamp, and is not intended to limit the creation. Further, the upper casing 14 U4 has opposite side edges, and each side edge forms a recess 112' to engage the opposite sides of the lower casing 115. For example, as shown in FIG. 1 to FIG. 4, a card protrusion 116 is formed outwardly on opposite sides of the lower casing 115 to be in contact with the groove 112 of the upper casing 114 to diffuse the diaphragm 13 Preferably, the ® is attached to the lower case 115. Furthermore, those skilled in the art can easily change the number of arc cylinders 'arrangement and shape'. For example, the arc cylinder of the lamp structure can be streamlined ^ 6/10 (Figure 7) No) or the diameter of the arc cylinder = body, preferably a cylinder of a quarter circle, but not here; in the spirit of this creation, the general knowledge in the field can be lightly created ° Other implementations of this creation, such changes in equivalence are in the scope of the rights claimed. From the second embodiment of the luminaire structure provided by the second 丨 丨 _ 及 及 及 及 利用 利用 利用 利用 利用 利用 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第 第The ingenious design of the devices at appropriate distances allows the self-illuminating device to uniformly scatter 2 rays. Moreover, the above embodiments do not need to use a diffusing agent, that is, the Lu Lu source is uniformly dispersed, and the lamp structure is high in brightness and anti-glare. The preferred embodiment of the present invention is not intended to be limited to the patent protection. Scope, therefore, the equivalent changes in the use of this creation manual and the Z in the schema are all included in this creation and are combined with Chen Ming.
