The specific embodiment
To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast accompanying drawing at present and specify the specific embodiment of the present invention.
Like Fig. 1-shown in Figure 6, the explosion-proof fluorescent tube 1 of LED of the present invention comprises lamp bar, outer lampshade 102, interior lampshade 103, housing 101.The lamp bar is provided with luminous LED, and the lamp bar in the present embodiment is tabular, and housing 101 is provided with the installed surface 117 that the lamp bar is installed, and the lamp bar is close to this installed surface 117 and is fixed on the installed surface 117 of housing 101 through fixed form such as bonding.Housing 101 in the present embodiment is processed by aluminium alloy, therefore needs between lamp bar and installed surface 117, be provided with insulating part, and both are kept apart, and can select for use silica gel as insulating part, and silica gel also has good thermal conductivity when insulating.Housing 101 is the cavity of hollow, in cavity, is provided with the control module of driving LED.Outer lampshade 102 and interior lampshade 103 all can printing opacities, and lampshade 103 shines out with outer lampshade 102 in the light transmission that LED sends.Outer lampshade 102 in the present embodiment is made of plastics with interior lampshade 103, and it is in light weight to compare the lampshade that conventional glass processes, and is easy to be shaped.Outer lampshade 102 is fixedly connected with housing 101 with interior lampshade 103, and interior lampshade 103 is between outer lampshade 102 and housing 101, and the lamp bar is between interior lampshade 103 and housing 101.Wherein interior lampshade 103 is tightly connected with housing 101, and both have formed the light-source chamber of sealing.Electronic components such as LED and control module are arranged in the light-source chamber, because light-source chamber is airtight, therefore inner electronic component is isolated from the outside, and inflammable gas or dust can not contact with electronic component, have realized explosion-proof purpose.Lampshade 103 is arranged between outer lampshade 102 and the housing 101 among the present invention; Therefore outside lampshade 103 can not be directly exposed in; The structure that is tightly connected of interior lampshade 103 and housing 101 also is hidden in inside; Sealing effectiveness is better, and fluorescent tube 1 inside has enough spaces to realize being tightly connected between interior lampshade 103 and the housing 101 simultaneously, seals explosion-proof being easy to and realizes.
Preferably, outer lampshade 102 has first flange 115, and interior lampshade 103 has second flange 116, is provided with first draw-in groove 113 that cooperates with first flange 115 on the housing 101 accordingly and cooperates second draw-in groove 114 of chucking with second flange 116.When lampshade 103 is with outer lampshade 102 in installing, with first flange 115 and second flange 116 slip into respectively first draw-in groove 113 and second draw-in groove 114 interior can accomplish fixing.Can coat fluid sealant in the gap between first flange 115 and first draw-in groove 113, also can coat fluid sealant in the gap between second flange 116 and second draw-in groove 114, further guarantee sealing effectiveness.
Preferably, the two ends of housing 101 have opening, after interior lampshade 103 is installed on the housing 101,, through screw sealing gasket 104 are fixed on the housing 101 simultaneously the openings at two ends sealing with sealing gasket 104.Housing 101, interior lampshade 103 and sealing gasket 104 threes form airtight light-source chamber.Sealing gasket 104 can be processed by materials such as silica gel, epoxy resin.The two ends of housing 101 also are provided with clamping piece 105 and plug 106, and clamping piece 105 compresses sealing gasket 104, install outer lampshade 102 backs and with plug 106 sealing are blocked at the two ends of housing 101.Pass plug 106, clamping piece 105 and sealing gasket 104 successively with screw then, and the three is fixedly connected.
Preferably, also be provided with wire hole 112 on the housing 101, the lead 111 that is connected with control module stretches out outside the housing 101 through wire hole 112.Lead 111 passes lead fixed nut 107, lead fixed tube 108, rubber parts 109 and cap 110 successively.Wherein lead fixed nut 107 is arranged in the housing 101, and cap 110 is arranged on outside the housing 101, and lead fixed tube 108 passes wire hole 112 and stretches in the housing 101.The upper and lower of lead fixed tube 108 all is provided with external screw thread; Screw-internal thread fit on the external screw thread on top and the cap 110; Screw-internal thread fit on the external screw thread of bottom and the lead fixed nut 107, and the external diameter on lead fixed tube 108 tops is greater than the aperture of wire hole 112, so lead fixed tube 108 can be blocked wire hole 112; Can coat fluid sealant in the gap between lead fixed tube 108 and the wire hole 112, realize sealing.Rubber parts 109 is arranged between lead fixed tube 108 and the cap 110, and when screwing cap 110, rubber parts 109 is by axial compression, and the gap between rubber parts 109 and the lead 111 is decreased to gradually and does not have the space, realizes further sealing.Lead 111 in the present embodiment is that the sidewall from housing 101 stretches out outside the housing 101, rather than stretch out from housing 101 openings at two ends.This is that the size of sealing gasket 104 is little, does not have enough spaces to realize the sealing to wire hole 112, possibly influence the sealing effectiveness of whole explosion-proof fluorescent tube 1 because housing 101 openings at two ends places are provided with sealing gasket 104.
As shown in Figure 7, the present invention also provides a kind of LED explosion-proof lamp, comprises the explosion-proof fluorescent tube 1 of support 201, end cap and above-mentioned LED.End cap is fixed on the support 201, and has the cavity of the plug 106 that can hold fluorescent tube 1.Support 201 is provided with two, is fixedly mounted on metope or other the fixing position.The two ends of fluorescent tube 1 are placed on respectively in the end cap, and the plug 106 at two ends is placed in the end cap, accomplish fixing.End cap also is provided with two; Comprise that first end cap 202 and second end cap, 203, the second end caps 203 comprise cylindrical shell 2031 and lid 2032, and cylindrical shell 2031 removably connects with lid 2032; Through being threaded, but also other implementation can be arranged in the present embodiment.When fluorescent tube 1 is installed, pull down lid 2032, then fluorescent tube 1 is passed cylindrical shell 2031 and place, after fixing, the lid 2032 of screwing on gets final product easy accessibility.It is understandable that to have at least to be dismountable getting final product in first end cap 202 and second end cap 203, be not limited to second end cap 203 shown in the present embodiment and comprise dismountable cylindrical shell 2031 and lid 2032.
Preferably, in order to improve the rigidity of support 201, on support 201, also be provided with reinforcement 204.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
