Fig. 1 is the axonometric chart of the illuminator 100 of the first specific embodiment according to the present invention.Fig. 2 It it is the front view of the illuminator 100 of the first specific embodiment according to the present invention.This illuminator 100 is omnidirectional lighting device in this embodiment.In conjunction with Fig. 1, Fig. 2 it can be seen that illuminator 100 include the first cover body 3 and the second cover body 4.Illuminator 100 also includes the first radiator 21 With the second radiator 22, the first cover body 3 and the second cover body 4 are arranged on the first radiator 21 and second Between radiator 22 and surround the first radiator 21 and major part of the second radiator 22.At it In its embodiment, it is also possible to be all coated with.First radiator 21 is not by the first cover body 3 and the second cover The lower end that body 4 surrounds offers multiple first blow vent 27.Illuminator 100 also includes for being electrically connected The electrical connection section 6 connect and the actuator housing 5 being connected with the lower end of the first radiator 21.
Fig. 3 is the top view of the illuminator 100 of the first specific embodiment according to the present invention.Wherein It can be seen that the top of illuminator 100 offers the second blow vent 28 for gas channel 25. On the inwall of the first radiator 21, it is provided with multiple cooling fin 29 simultaneously.
Fig. 4 is the sectional view that line A-A obtains along Fig. 2.It will be clear that quilt from Fig. 4 The internal structure that first cover body 3 and the second cover body 4 surround.Illuminator 100 includes the first luminous group Part 1 and the second luminescence component 1 '.Illuminator 100 also includes heat abstractor 2.The most real at this Executing in example, heat abstractor 2 includes integral part of first radiator 21 and the second radiator 22.The One radiator 21 has perisporium.This perisporium is around gas channel 25.The outer surface of perisporium is bending Surface, this curved surface can be reflecting surface, using as the reflector for adjusting beam direction.For Formation omnidirectional lighting, is provided with the first luminescence component 1 and the second luminescence component 1 '.Second radiator 22 bulge loops being around the first radiator 21, pacify on the end face 23 and bottom surface 24 of this bulge loop respectively Put the first luminescence component 1 and the second luminescence component 1 ', it is achieved thereby that bilateral arranges the structure of luminescence component Think, it is achieved that omnidirectional lighting.The curved surface of the first radiator 21 is divided into by the second radiator 22 Upper reflecting surface and lower reflecting surface.Upper reflecting surface is for coordinating with the first luminescence component 1, and lower reflecting surface is used In coordinating with the second luminescence component 1 '.Upper reflecting surface and lower reflecting surface can be free concave curved surfaces, and The profile of upper reflecting surface and lower reflecting surface can be adjusted according to the situation of luminescence component to realize more preferably Illuminating effect.
First luminescence component 1 and the second luminescence component 1 ' include the annular circuit board with opening respectively 11 and the circumference that is distributed on described annular circuit board 11 on multiple LED chip 12, annular electro Road plate 11 utilizes opening sleeve to be located on the first radiator 21, and and then is arranged to around the first radiator On second radiator 22 of 21.In order to realize preferable illuminating effect, LED chip 12 is in circumference On be evenly arranged on annular circuit board 11 and symmetrical relative to the first radiator 21.
Equally, the perisporium of the first radiator 21 be divide into and protrudes from up by the second radiator 22 The Part I 211 of two radiators 22 and protrude from the Part II of the second radiator 22 in lower section 212.In order to effectively dispel the heat, perisporium around gas channel 25 include two from top to bottom Individual part, the chimney passage 251 in order to produce stack effect the most above and be positioned at lower section be Guide the air guiding flow passage 252 of air.To this end, in this embodiment, Part I 211 sets It is calculated as the section that two ends diameter is big and mid diameter is little.Figure 4, it is seen that Part I 211 Diameter start constantly to be gradually reduced until the minimum section of diameter at the second blow vent 28, so After start constantly to become larger from the section that diameter is minimum.Part II 212 and Part I 211 Joining distal ends and define that the end from Part I 211 starts that diameter becomes larger tubaeform Section.This air guiding flow passage 252 sucks cold air from the first blow vent 27, and is inhaled by perisporium The first and second luminescence components 1 received, heat transfer produced by 1 ' gradually goes up to cold air, cold air Rising and be heated, enter into chimney passage 251, due to the stack effect of chimney passage 251, heat is empty Gas is promptly discharged from the second blow vent 28.
First radiator 21 has the holding section 213 for engaging with actuator housing 5 in lower end. Owing in the present invention, the first radiator 21 and the second radiator 22 utilize chimney passage 251 and air to lead The radiating effect that circulation road 252 produces is good, it is therefore not necessary to arrange in addition to cooling fin 29 Other fin, has saved the space shared by heat abstractor, provides in a large number to actuator housing 5 Design space.
Fig. 5 is that the illuminator 100 of the first specific embodiment according to the present invention is eliminating cover body In the case of the first axonometric chart；Fig. 6 is the illuminator of the first specific embodiment according to the present invention 100 the second axonometric charts in the case of eliminating cover body.It is positioned at the second heat radiation as seen from Figure 5 Second luminescence component 1 ' of body 22 bottom surface 24.Second luminescence component 1 ' includes annular circuit board 11 He The multiple LED chip 12 being evenly distributed in circumference on annular circuit board 11.As seen from Figure 6 It is positioned at the first luminescence component 1 of the end face 23 of the second radiator 22.First luminescence component 1 includes ring The multiple LED chip 12 being evenly distributed on shape circuit board 11 and circumference on annular circuit board 11. Assembling illuminator 100 of the present invention when, first can dispose first on end face 23 Optical assembly 1.Second luminescence component 1 ' can be designed to two half ring segments, correspondingly, loop circuit Plate 11 is also configured as two half ring segments, is pacified respectively by two half ring segments of the second luminescence component 1 ' Install on two half ring segments of annular circuit board 11 to be combined into complete annular.Afterwards by One cover body 3 and the second cover body 4 be respectively installed to the first radiator 21 and described second radiator 22 it Between, limit for surrounding the first luminescence component 1 and closed cavity of the second luminescence component 1 '.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for ability For the technical staff in territory, the present invention can have various modifications and variations.All spirit in the present invention and Any modification, equivalent substitution and improvement etc. made within principle, should be included in the protection of the present invention Within the scope of.
