The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
See also Fig. 1 and Fig. 2, the LED lamp of one embodiment of the invention comprises two illuminating module 100 that the up and down is stacked, and this two illuminating module 100 is symmetrical set.Each illuminating module 100 comprises lamp housing 10, be placed in light emitting diode module 20 in lamp housing 10, be placed in lamp housing 10 and cover is put the lampshade 30 of described light emitting diode module 20, and in order to the fixture 40 of fixing described lampshade 30.
Above-mentioned lamp housing 10 is tubbiness, and it has an opening (not indicating).This lamp housing 10 comprises that substrate 12 reaches by the downward extended cylindrical shell 14 of substrate 12 outer peripheral edges.This lamp housing 10 can by metal material such as aluminium, iron and both alloy etc. be made into integration.In the present embodiment, described substrate 12 is rounded, and cylindrical shell 14 is cylindric.Offer port 140 on the cylindrical shell 14 of described lamp housing 10.The quantity of described port 140 is a plurality of, these ports 140 evenly, be distributed on cylindrical shell 14.Described port 140 is bar shaped, along the circumferential extension of this cylindrical shell 14 and connect this cylindrical shell 14.
Above-mentioned light emitting diode module 20 comprise a circular circuit board 22 and some evenly, the interval adheres on the light emitting diode 24 on this circuit board 22.Described circuit board 22 is arranged on described substrate 12, and light emitting diode 24 is towards the opening setting of lamp housing 10.The quantity of described light emitting diode 24 can be according to the concrete power of LED lamp and difference.
Above-mentioned lampshade 30 comprises tubular cover body 32 and the cover plate 34 that combines with these cover body 32 1 end openings.Described cover body 32 is placed in lamp housing 10, and the interior sidewall surface of the cylindrical shell 14 of corresponding applying lamp housing 10.This lampshade 30 can be made into integration by glass, resin, plastic or other material, understandably, the cover body 32 of this lampshade 30 also can separate with cover plate 34 and forms, the material that adopts also can be different, adopt metal materials such as aluminium, iron, alloy etc. as cover body 32, and cover plate 34 is made by glass, resin or plastics.Described cover plate 34 is in the form of annular discs, and its corresponding lid is placed in described cover body 32 near an end of lamp housing 10 openings, in order to seal this cover body 32.The middle part of this cover plate 34 upwards has been recessed to form depressed part 340.The end face central authorities of this depressed part 340 offer through hole 342, use for described fixture 40 to be placed through in depressed part 340.
