[specific embodiment]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is fitting structure schematic diagram in an embodiment.The protecgulum 200 that this light fixture Transparent Parts device comprises back cover 100, be connected with back cover 100 and be successively set on back cover 100 and protecgulum 200 between and reflector 300, Transparent Parts 400, dust ring 500 and the protective glass plate 600 of butt.In back cover 100, be provided with light source, reflector 300 adaptations are arranged in back cover 100, Transparent Parts 400, dust ring 500 and protective glass plate 600 are arranged in protecgulum 200, and reflector 300 reflects the light of light source and concentrates through Transparent Parts 400 and protective glass plate 600 and penetrate.Protective glass plate 600 is arranged between protecgulum 200 and Transparent Parts 400 Transparent Parts 400 is protected, and dust ring 500 is arranged between Transparent Parts 400 and protective glass plate 600 and carries out sealing and dustproof.
Fig. 2 is the structure top view of Transparent Parts in an embodiment, and Fig. 3 is the structure cutaway view of Transparent Parts in an embodiment.In conjunction with Fig. 1 to Fig. 3, Transparent Parts 400 is column type, cave in to be formed for receiving by one side mutually with reflector 300 and connect the reflector accommodating cavity 410 of reflector 300, cave in and form the sheet glass accommodating cavity 420 that holds protective glass plate 600 by one side mutually with protective glass plate 600, sheet glass accommodating cavity 420 diapire spirogyrates circularize boss 430, and annular boss 430 outer diameters are less than sheet glass accommodating cavity 420 sidewall diameters and surround the dust ring position-arresting groove 440 of taking over control konisphere 500 for receiving with sheet glass accommodating cavity 420 sidewalls.
Fig. 4 is front-cover structure schematic diagram in an embodiment.In conjunction with Fig. 1 to Fig. 4, when this lamp assembled, reflector 300 is arranged in back cover 100, dust ring 500 is packed in the sealing ring position-arresting groove 440 of Transparent Parts 400 and protective glass plate 600 is placed in the sheet glass accommodating cavity 420 of Transparent Parts 400 and be pressed on dust ring 500, then by Transparent Parts 400, dust ring 500 and protective glass plate 600 pack in protecgulum 200 by the mode of withholding or bonding way together, again protecgulum 200 is threaded by the internal thread of protecgulum 200 inwalls and the external screw thread of back cover outer wall with back cover 100, by in back cover 100 precession protecgulums 200.In the process of back cover 100 continuous precession protecgulums 200, reflector 300 enters in reflector accommodating cavity 410 and with Transparent Parts 400 and contacts, Transparent Parts 400 is exerted pressure, spacing due to protecgulum 200, make dust ring 500 constantly compressed, until dust ring 500 be compressed into assemble to greatest extent complete.This light fixture, protective glass plate 600 is arranged between Transparent Parts 400 and protecgulum 200, by Transparent Parts 400 and external isolation, is spent impairedly thereby effectively put only Transparent Parts 400 by outside hard things mill, affects the bright dipping of light fixture.Meanwhile, dust ring 500 carries out sealing and dustproof to protective glass plate 600 and Transparent Parts 400, effectively prevents that dust from entering between protective glass plate 600 and Transparent Parts 400, affects light fixture bright dipping.
Fig. 5 is Transparent Parts structure cutaway view in another embodiment.Fig. 6 is cover plate chip architecture cutaway view in another embodiment.In this embodiment, Transparent Parts 400 is column type, cave in to be formed for receiving by one side mutually with reflector 300 and connect the reflector accommodating cavity 410 of reflector 300, cave in and form the sheet glass accommodating cavity 420 that holds protective glass plate 600 by one side mutually with protective glass plate 600, sheet glass accommodating cavity 420 diapires are recessed to form the dust ring position-arresting groove 440 of taking over control konisphere 500 for receiving.Protective glass plate 600 is dome type, and one end is openend, has inner chamber, and openend inner diameter is greater than dust ring position-arresting groove 440 internal diameters, can buckle closure on dust ring 500.
In other embodiments, Transparent Parts is column type, caving in to be formed for receiving by one side mutually with reflector connects the reflector accommodating cavity of reflector, caves in and forms the sheet glass accommodating cavity that holds protective glass plate mutually with protective glass plate by one side, and the diapire spirogyrate of sheet glass accommodating cavity circularizes boss.Be with above-described embodiment difference, dust ring is O type rubber ring.Protective glass plate is column type, lateral wall diameter mate with sheet glass accommodating cavity diameter and outer wall on cave in to be formed for receiving and take over control the dust ring position-arresting groove of konisphere.
Or Transparent Parts is column type, caving in to be formed for receiving by one side mutually with reflector connects the reflector accommodating cavity of reflector, caves in and forms the sheet glass accommodating cavity that holds protective glass plate mutually with protective glass plate by one side.Be with above-described embodiment difference, dust ring is O type rubber ring.Protective glass plate is dome type, lateral wall diameter mate with sheet glass accommodating cavity diameter and outer wall on cave in to be formed for receiving and take over control the dust ring position-arresting groove of konisphere.
Above-mentioned light fixture, between Transparent Parts and protecgulum, be provided with and prevent that hard thing from causing mill to spend impaired protective glass plate to Transparent Parts, thereby can either guarantee the impact strength of light fixture, can effectively prevent that again Transparent Parts surface abrasion from affecting the bright dipping of light fixture, safety and the performance of light fixture are guaranteed greatly, the Material Selection that has solved Transparent Parts design, greatly reduces cost, has saved expense.
Meanwhile, between protective glass plate and Transparent Parts, be provided with and carry out sealing and dustproof, prevent that dust from entering the dust ring between protective glass plate and Transparent Parts, further reduced the impact of dust on light fixture bright dipping.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
