TECHNICAL FIELD
[0001] The utility model relates to a lamp tube technical field especially relates to a LED lampshade. BACKGROUND
[0002] The LED lampshade is one kind of LED straight tube lamp accessories, and the main function of the LED lampshade is to better gather the light emitted by LED lamp beads, so that the light is more uniform and softer, and direct glare of the light emitted by the LED lamp beads is avoided. Meanwhile, the LED lampshade can reduce power compared with the traditional LED straight tube lamp under the premise that the use scene meets the illumination, prolong the service life of the LED lamp, and play the energy-saving effect. In the prior art, the structure of the existing LED lamp tube is mainly that the inner side is a smooth circular arc, when the light is emitted from the lampshade, the light on both sides of the arc surface of the lampshade is relatively dark, and the light emitted from both sides of the lampshade is less. In addition, since the ordinary LED straight tube lamp needs to make the light emitted by the lamp beads softer, a softening agent is added in the material of the lampshade, and the light emitted by the LED lamp beads will be lost when passing through the lampshade. In order to improve the lighting effect, the power of the LED lamp will be increased, which will increase the power consumption. SUMMARY
[0003] In view of the deficiencies in the prior art, the utility model provides a LED lampshade, which solves the problems of weak light on both sides of the lampshade and unsatisfactory lighting effect in the prior art.
[0004] According to the embodiment of the utility model, a kind of LED lampshade, the lampshade is strip-shaped and the section is circular or semicircular arc, including first rack light distribution area and second rack light distribution area and middle light collecting area, first rack light distribution area and second rack light distribution area are respectively arranged in the lampshade center line vertical plane two sides, first rack light distribution area and second rack light distribution area include several parallelly arranged racks, the extension line of rack and the center line of lampshade are parallel, middle light collecting area is arranged in the region between first rack light distribution area and second rack light distribution area of lampshade inner wall, and the middle light collecting area is the arc surface that protrudes to lampshade interior.
[0005] The technical principle of the utility model is as follows: when light is emitted from the lampshade, the light meets the rack, and the light emitted by the light source is transmitted along the refracted direction of the rack, so that the originally relatively downward concentrated light is dispersed; the middle light collecting area concentrates the light in the middle region, and improves the brightness of the irradiation region.
[0006] Preferably, the two sides of the lampshade are provided with inwardly extending protrusions.
[0007] Preferably, the corresponding radian of the middle light collecting area is 60-80 °.
[0008] Preferably, the material of the lampshade is polycarbonate.
[0009] Preferably, the sharp part of the rack faces the central light-concentrating area.
[0010] Preferably, the curvature of the central focusing area is consistent with the outer curved surface of the lampshade.
[0011] Compared with existing technologies, this invention has the following advantages: The brightness of the central illumination area is further improved by using a convex lens to focus the light, ensuring illumination effect without increasing the power of the light source; simultaneously, the light is evenly dispersed by the rack and pinion reflector, resulting in a wider effective illumination range and avoiding dim light from the sides of the lampshade; furthermore, because the polycarbonate material used in the rack and convex lens structure of the lampshade is made without added light softener, the overall light transmittance is improved while the light does not cause glare to the naked eye; compared with existing ordinary LED tube lights, it can reduce power by about 30% while meeting scene illumination requirements, achieving energy saving and emission reduction. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of this utility model.
[0013] In the above attached figures: 1. Lampshade; 2. First rack light distribution area; 3. Second rack light distribution area; 4. Central focusing area; 5. Protrusion. Detailed Implementation
[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0015] like Figure 1 As shown in the figure, this utility model embodiment proposes an LED lampshade 1. The lampshade 1 is elongated and has a circular or semi-circular cross-section. It includes a first rack and pinion light distribution area 2, a second rack and pinion light distribution area 3, and a central focusing area 4. The first rack and pinion light distribution area 2 and the second rack and pinion light distribution area 3 are respectively disposed on both sides of a vertical surface passing through the center line of the lampshade 1. The first rack and pinion light distribution area 2 and the second rack and pinion light distribution area 3 include a plurality of racks arranged in parallel. The extension lines of the racks are parallel to the center line of the lampshade 1. The central focusing area 4 is disposed on the inner wall of the lampshade 1 and located in the area between the first rack and pinion light distribution area 2 and the second rack and pinion light distribution area 3. The central focusing area 4 is an arc-shaped surface that protrudes 5 into the lampshade 1. When light passes through the first rack and pinion light distribution area 2 and the second rack and pinion light distribution area 3, the light is refracted on the side of the racks, causing the refracted light to be directed toward the side of the lampshade 1, thereby increasing the amount of light emitted from both sides of the lampshade 1 and improving the brightness of the sides. After passing through the central focusing area 4, the emitted light is further centered within this area by the material of the convex lens, thus optimizing the brightness of the central illumination area without increasing the power of the light source. The included angle between two adjacent racks is between 10-30°.
[0016] Preferably, the lampshade 1 has inwardly extending protrusions 5 on both sides. When installing the lampshade 1, the protrusions 5 are engaged in the installation position by moving the lampshade 1 along the axis.
[0017] Preferably, the arc of the central focusing area 4 is 60-80° to avoid the central focusing area 4 affecting the light on both sides, and the light emitted from the lampshade 1 can illuminate the effective range with uniform brightness.
[0018] Preferably, the lampshade 1 is made of polycarbonate. Polycarbonate has strong dimensional stability and temperature changes have little impact on its mechanical strength, meaning that its performance remains reliable even in extreme environments.
[0019] Preferably, the sharp part of the rack faces the central light-concentrating area 4, so that the two adjacent sides of the sharp part of the rack can better refract light.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
