Following will be combined with the drawings in the embodiments of the present invention, and technical scheme in the embodiment of the invention is clearly and completely described, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.
It is the stereoscopic schematic diagram of one embodiment of lampshade of the present invention also referring to Fig. 1-Fig. 3, Fig. 1, Fig. 2 is the schematic top plan view of one embodiment of lampshade of the present invention, and Fig. 3 is intended to indicate that the schematic cross-section in the direction A-A in Fig. 2 of lampshade internal light transmission path.
The lampshade of the present embodiment includes canopy main body 10 and at least light guide section 11 that is set on canopy main body 10.
Further, light guide section 11 includes an at least incidence surface 110 and an at least reflecting surface 111, incidence surface 110 is used to receive the light from the major axes orientation incidence of canopy main body 10, reflecting surface 11 is obliquely installed with respect to incidence surface 110, and the tilt angle of reflecting surface 111 to be totally reflected through the incident light of incidence surface 110 in reflecting surface 111.
Since 11 selected materials of light guide section are different, its refractive index is also corresponding different, therefore the tilt angle of the reflecting surface 111 of light guide section 11 and the plane of incidence 110 need to be determined according to the position of light source, launch angle and 11 material therefor of light guide section, so that the light that light source projects go out is totally reflected after 11 incidence surface of light guide section, 110 incidence in reflecting surface 111, and then achieve the purpose that change light transmission direction.Specifically 11 material of light guide section can be PC (Polycarbonate, polycarbonate) or PMMA (Polymethyl Methacrylate, polymethyl methacrylate), but it is not limited only to this.
For example, the angle of total reflection of PC material is about 39 ° when using PC material, therefore it need to only guarantee that light is greater than or equal to 39 ° with the incidence angle of reflecting surface 111 after incidence surface 110 reflects, so that it may so that light is totally reflected on reflecting surface 111.
By the above-mentioned means, receiving the light from canopy main body major axes orientation incidence using the incidence surface of light guide section, and carried out entirely to it by the surface of emission by the way that an at least light guide section is arranged on canopy main body
Reflection, and then effectively change light transmission direction, and reach expected optical effect.
In the present embodiment, light guide section 11 is set to inside canopy main body 10, and is integrally formed with canopy main body 10.For example, canopy main body 10 and light guide section 11 are integrally formed using injection molding process.Light guide section 11 can be hollow or solid construction, and incidence surface 110 and reflecting surface 111 can be rectangular-shaped or circular shape, but be not limited only to this, and its quantity is not limited to one described in figure, but can according to need and carry out any setting.Further, in order to simplify processing procedure and design, in the present embodiment, incidence surface 110 and the main shaft of canopy main body 10 are arranged in parallel.In other embodiments, incidence surface 110 can be arranged with the inclined main axes of canopy main body 10, if angle is ± 35 °.Further, lampshade further comprises at least one card slot 12, and card slot 12 is used to for lampshade being fixed on other devices (such as: unmanned plane).
Further, 10 material energy transmitted light of canopy main body, light transmission form includes that material is transparent, material is translucent or material is transparent and surface atomizing is handled, when so that light being projected through canopy main body 10, second of radiology effect can be generated, the light spread is enable more uniformly to spread out.
In a particular application, it can achieve expected optical effect by the way that light guide section 11 is arranged.For example, the major axes orientation of light towards canopy main body 10 that the reflecting surface 111 through light guide section 11 is totally reflected converges, and then the utilization rate of light source can be improved in Fig. 3.Further, the quantity of light guide section 11 is at least two, and around the major axes orientation equidistantly spaced of canopy main body 10.Thus since, into each light guide section 11 light after reflecting surface 111 is totally reflected, the transmission direction for the light in interval region for converging towards the major axes orientation of canopy main body 10, and entering between the light guide section 11 that is disposed adjacent does not change substantially.Therefore, shinny region is formed in the corresponding position of light guide section 11, and the corresponding position of the interval region between the light guide section 11 being disposed adjacent forms obfuscation region, to form alternately dark and bright rings shape optical design.
It is appreciated that light guide section 11 can also be alternatively arranged around the major axes orientation Unequal distance of canopy main body 10, to show different displays.
Further, canopy main body 10 includes dome portion 100 and cyclic annular trunk portion 101.Wherein, dome portion 100 is set to one end of cyclic annular trunk portion 101, and the major axes orientation of canopy main body 10 is the central axes direction of cyclic annular trunk portion 101.In the present embodiment, light guide section 11 is connect with dome portion 100, so that the light reflected through reflecting surface 111 sheds from dome portion 101；So that seeing
The person of examining can be from 101 unilateral observation of dome portion to corresponding optical design.
Further, the tilt angle of reflecting surface 111 and the curvature in dome portion 100 are arranged so that range incident to the light of incidence surface 100 becomes the parallel rays for being parallel to 10 major axes orientation of canopy main body after reflecting surface 111 and dome portion 100 act at a predetermined angle from the predetermined position of the main shaft of canopy main body 10.
Through the above way, the uniformity of lampshade emergent ray can be improved, and light guide section 11 be formed by optical design (for example, being previously mentioned alternately dark and bright rings shape optical design) can be observed in distance relatively far away from, and then play good instruction and identification effect.
In above-mentioned diagram, size, shape and the relative positional relationship of light guide section 11 are only to illustrate, and practical application can be changed as needed.For example, in other embodiments, the formation of lampshade can be first by 11 Unitary injection formed of light guide section after, then each light guide section 11 is fixed on canopy main body 10.
