Further, the pedestal upper end arches upward in protrusion plane, and lower end outwards annularly extends, and its development length is less than Shell body development length.
Further, the Section Bar Heat Sinks lower end is built in interior inlay upper cavity, and section bar radiates after assembling Fitted with anti-guncotton upper end device lower end outer ring.
Further, the substrate is located at the lower portion that support is formed.
Further, the shell body, interior inlay, anti-guncotton, support, substrate are circle.
Further, the lens upper end is provided with circular groove, and the groove diameter is not less than light-emitting diodes length of tube.
Further, the support material is ferrous material, and the magnet retainer ring material is plastics.
Beneficial effect：
Structure of the present invention is novel, from the internal structure of lighting device of the present invention, and type is provided with fire prevention lighting device Material radiator, can effectively strengthen the heat dissipation of lighting device in the course of the work, reduce bulk temperature, improve using safety Property；Lighting device of preventing fires is interior anti-guncotton, when running into the condition of a fire, and anti-guncotton meets fire expansion, has delayed Section Bar Heat Sinks significantly Thawing, obstructed spreading for the intensity of a fire, also striven for safety time to personnel escape.
In addition, untouchable ring of the invention, support and anti-guncotton are fire proofing, also can be effective after intensity of a fire generation Fire spreading is obstructed, plays a part of barrier intensity of a fire expansion.
Brief description of the drawings
Fig. 1 is overall structure diagrammatic cross-section of the present invention.
Fig. 2 is Structure explosion diagram of the present invention.
Wherein, 1 is shell body, and 2 be Section Bar Heat Sinks, and 3 be anti-guncotton, and 4 be support, and 5 be substrate, and 6 be magnet retainer ring, 7 be untouchable ring, and 8 be lens, and 9 be light emitting diode, and 10 be interior inlay.
Embodiment
With reference to accompanying drawing, the present invention is described in further details.
As shown in drawings, a kind of fire prevention lighting device for LED lamp, including：
Inlay card in a kind of fire prevention lighting device for LED lamp, including hollow shell body 1, the shell body 1 Interior inlay 10 is connected to, the interior upper end of inlay 10, which is provided with anti-guncotton 3, the shell body 1, is provided with Section Bar Heat Sinks 2, the type Material radiator 2 is located at the anti-top of guncotton 3, and the anti-lower section of guncotton 3 is additionally provided with support 4, and the upper end of support 4, which is provided with, can house type The opening of material radiator 2, its bottom is placed in support 4 after the Section Bar Heat Sinks 2 are installed, and the lower section of support 4 is provided with Substrate 5, the substrate 5 is connected in Section Bar Heat Sinks 2 by screw through support 4, and light-emitting diodes are welded with the substrate 5 Pipe 9, the lower section of the light emitting diode 9 is provided with lens 8, the lens 8 by buckle structure and the inner edge clamping of magnet retainer ring 6, The upper end of magnet retainer ring 6, by snapping connection, is provided with magnet, magnet and untouchable ring with support 4 in the magnet retainer ring 6 7 magnetic, the outer rim of shell body 1 outwards annularly extends and is provided with bayonet socket, the outer rim of magnet retainer ring 6 in its peripheral end portion Provided with the bayonet socket being engaged with the peripheral end portion of shell body 1；The upper end of support 4 is arched upward in protrusion plane, and lower end is outwards annular in shape Extension, its development length is less than the development length of shell body 1；The lower end of Section Bar Heat Sinks 2 is built in the interior upper cavity of inlay 10 It is interior, and the lower end outer ring of Section Bar Heat Sinks 2 is fitted with the anti-upper end of guncotton 3 after assembling；The substrate 5 is located at what support 4 was formed Lower portion；The shell body 1, interior inlay 10, anti-guncotton 3, support 4, substrate 5 are circle；The upper end of lens 8 is provided with circle Groove, the groove diameter is not less than the length of light emitting diode 9；The material of support 4 is ferrous material, the magnet retainer ring 6 materials are plastics.
When indoor on fire when, the intensity of a fire can be by untouchable ring 7 and the ferrous material of support 4 when touching this fire prevention lighting device Stop, when the intensity of a fire bypasses untouchable ring 7 and support 4, lens 8 will be melted by the flame of high temperature, after lens 8 are melted, support 4 The outer ring intensity of a fire can still be stopped, and now inner ring is light emitting diode 9 and substrate 5, because substrate 5 and Section Bar Heat Sinks 2 have There is certain thickness, the especially thickness of Section Bar Heat Sinks 2 is larger, and also have between substrate 5 and Section Bar Heat Sinks 2 added with one layer Anti- guncotton 3, anti-guncotton 3 can expand after the intensity of a fire is run into, first, substrate 5 is acted on metal fireproof, the intensity of a fire can be invaded and illuminated Retarding action is played inside device, second, anti-guncotton 3 can play a protective role after expanding to Section Bar Heat Sinks 2 so that section bar dissipates Hot device 2 will not melt within a very long time, obstruct spreading and the damage to superstructure for the intensity of a fire, while also giving personnel More times have been striven in escape.
Structure of the present invention is novel, from the internal structure of lighting device of the present invention, is set in fire prevention lighting device There are Section Bar Heat Sinks 2, can effectively strengthen the heat dissipation of lighting device in the course of the work, reduce bulk temperature, raising is used Security；Lighting device of preventing fires is interior anti-guncotton 3, and when running into the condition of a fire, anti-guncotton 3 meets fiery expansion so that Section Bar Heat Sinks 2 It will not melt within a very long time, obstruct spreading for the intensity of a fire, also striven for safety time to personnel escape.Except this it Outside, untouchable ring 7 of the invention, support 4 and anti-guncotton 3 are fire proofing, and it is climing also can effectively to obstruct the intensity of a fire after intensity of a fire generation Prolong, play a part of barrier intensity of a fire expansion.
