Embodiment

In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

Please, in the lump referring to figs. 1 through Fig. 4, Fig. 8 and Fig. 9, now LED baton provided by the invention is described.The LED baton, comprise power supply 1, LED substrate 2, LED light-emitting component 3 and the barred body 4 of being made by optical plastic, LED light-emitting component 3 is located on LED substrate 2, LED substrate 2 is electrically connected to power supply 1, one end 41 of barred body 4 is made as the frustum of a cone 411, the upper surface of the frustum of a cone 411 caves inward and is provided with accommodating cavity 410, and LED light-emitting component 3 docks with accommodating cavity 410; The other end 42 of barred body 4 inwardly is provided with the light-reflecting portion 420 that the ring-shaped step 421 that successively decreased successively by a plurality of diameters forms from outer end.

With existing baton, compare, LED baton structure of the present invention is simple, its barred body 4 can be made by various common optical materials, cave inward and be the light-reflecting portion 420 of ledge structure by the end design at barred body 4, the light that other end LED light-emitting component 3 sends can obtain effectively reflection and guiding in real time is dispersed, thereby efficiently utilizes luminous energy, and not only brightness is high to make barred body 4, and luminous evenly, greatly promoted applicability and the visual validity of baton.

Further, please in the lump referring to Fig. 3, Figure 11 and Figure 12, as a kind of embodiment of LED baton provided by the invention, the bottom surface 4101 of accommodating cavity 410 is the arc surface consistent with the exiting surface radian of LED light-emitting component 3.Like this, after the refraction of bottom surface 4101, quite a few forms the parallel light velocity from an end-fire of barred body 4 to the other end 42 to the light sent from LED light-emitting component 3, then advancing the step reflecting surface reflection guiding of the reflecting part 420 of this end returns, further strengthen the brightness of barred body 4, and good uniformity, referring to Figure 11 and Figure 12 luminous intensity distribution schematic diagram.

Further, refer to Fig. 5, Fig. 6 and Figure 11, Figure 12, as a kind of embodiment of LED baton provided by the invention, the tapering a of the frustum of a cone 411 is 80 °～100 °.In this angular range, can well the light sent from LED light-emitting component 3 be continued to reflection again through offside reflection to the side of barred body 4 of the frustum of a cone 411, make most light beam to arrive the other end 42 by barred body 4, thereby strengthen the brightness of barred body 4.

Further, referring to Fig. 5, Fig. 8, Fig. 9 and Figure 11, as a kind of embodiment of LED baton provided by the invention, at the other end 42 of barred body 4, ring-shaped step 421 coaxial inner conductors of light-reflecting portion 420.The width that can guarantee like this each step anchor ring is consistent.Specifically, the ring-shaped step internal diameter size successively reduces, and eight steps for example can be set, and certainly, is not limited to arrange eight steps, and on theory, the quantity setting of step is more, and what more be conducive to light effectively guides to barred body 4 inside; As each ring-shaped step 421 internal diameter Φ 8>Φ 7>Φ 6>Φ 5>Φ 4>Φ 3>Φ 2>Φ 1 successively from outside to inside, so just form a plurality of reflective steps faces that do not block mutually, the light of coming from LED is reflected at these step surfaces, part light beam directly reflects back into an end 41 at LED place, part light reflexes to the side of barred body 4 through these step surfaces, continue again to reflex to the inside of barred body 4, make light beam be lost to the minimizing in barred body 4 outsides, light loss reduces, thereby effectively utilizes luminous energy.

Further, also refer to Fig. 5, Fig. 8, Fig. 9 and Figure 11, a kind of embodiment as LED baton provided by the invention, the internal diameter size of the ring-shaped step 421 of light-reflecting portion 420 is equal difference and successively reduces, specifically: Φ 8-Φ 7=Φ 7-Φ 6=Φ 6-Φ 5=Φ 5-Φ 4=Φ 4-Φ 3=Φ 3-Φ 2=Φ 2-Φ 1, this equal difference is evenly successively decreased and is made the size of step and step even, more being conducive to light evenly and is effectively guided by ground and is reflected, make the brightness of barred body 4 even, and brightness is high.

Further, refer to Fig. 7, Fig. 8 and Figure 11, a kind of embodiment as LED baton provided by the invention, the height of each ring-shaped step 421 equates, be specially: L1=L2-L1=L3-L2=L4-L3=L5-L4=L6-L5=L7-L6, equally, the equal structural design of height of this ring-shaped step 421 also greatly is conducive to light and is guided equably and reflect.

Further, referring to Fig. 1 to Fig. 3 and Figure 10, a kind of embodiment as LED baton provided by the invention, this LED baton also comprises handle 10, the front end of handle 10 is provided with installation cavity 101, LED substrate 2 and LED light-emitting component 3 are located in installation cavity 101, and the end that barred body 4 is provided with the frustum of a cone 411 embeds and is fixedly linked in installation cavity 101.Handle 10 has been arranged, facilitated the user to the holding of baton, LED substrate 2 and LED light-emitting component 3 have been located to the installation cavity 101 of handle 10 simultaneously, can play fixing and protective effect to it.Certainly, on handle, lanyard etc. can also be set, in order to prevent whole baton from being circle, easily from table top, roll down and it is damaged, the periphery design of handle 10 can be become to the shapes such as prism.

Further, refer to Fig. 2 and Figure 10, power supply 1 is battery, is provided with battery case 102 in handle 10, and battery is placed in battery case 102, simple in structure, connects reliable.What certainly match with it also arranges power switch on handle 10.

Further, refer to Fig. 1, Fig. 2 and Figure 10, as a kind of embodiment of LED baton provided by the invention, barred body 4 is spirally connected with the installation cavity inwall of handle 10.That is: in the periphery of barred body 4 and the installation cavity inwall of handle 10, suitable external thread and internal thread are set respectively, this mode of being spirally connected connects reliably, also is convenient to dismounting and safeguards; Certainly can be also other connected modes such as clamping, bolt between the two.

Further, as the embodiment of LED baton provided by the invention, barred body 4 is made for PMMA or PC material.Polymethylmethacrylate (PMMA), be commonly called as organic glass, is the best plastics of optical property.PMMA can injection moulding, extruding also can cast molding with the thermoforming transparent article, easy to process.And polycarbonate (PC) is the transparent engineering plastics of high comprehensive performance, the PC optical property is only lower than PMMA.But injection, extrude with the high-quality PC transparent article of blowing higher technological requirement is arranged.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
