Description of drawings
Fig. 1 is the part front cross-sectional view that is installed in the following illuminator in the ceiling panel according to the present invention;
Fig. 2 is the part side cross-sectional, view of illuminator down shown in Figure 1;
Fig. 3 is the vertical view of illuminator down shown in Figure 1.
The specific embodiment
Hereinafter, top, bottom, side and similar term relate to the orientation with reference to illuminator down shown in the drawings and plan use, and must not limit as other just to easy to use.
Shown in the accompanying drawing 1, following illuminator 1 is installed in the hole 2 that is formed in the gypsum plaster ceiling board panel 3.
Following illuminator 1 comprises a cover body 4, and said cover body 4 is processed by the steel of 1 millimeters thick, and scribbles powder.Said cover body 4 has one to be columniform sidewall basically, lower ending opening (like figure), and upper end closed forms down the top 5 of illuminator.The center at said cover body 4 tops 5 or near have the aperture of diameter 5 millimeter circular.This hole can supply a pair of insulated electric conductor 7 to penetrate in the said cover body, and a plastics buttonhole 6 is housed in the hole, prevents that the incisxal edge in 5 formation holes, cover body 4 steel tops from damaging electric wire 7.The size in hole gear to actual circumstances ground as far as possible little.
Except 2 groups of each 4 air channels 8, the cylindrical wall of said cover body is continuous basically, and these two groups of air channels are arranged at the opposite flank of cylindrical cover body respectively.The heat that lamp 10 is produced in the cover body can distribute through air channel 8.Air channel 8 is through cutting a slit and the following cylindrical wall of slit being formed to internal strain on cylindrical wall.Thereby air or other material will flow to the outside through the inside from cover body 4 in the air channel 8, must the air channel that be passed down through as shown in arrow 9.Each air channel extends about 2.5 centimetres along cover body 4 peripheries.The slit of air channel 8 is all substantially parallel each other, between the groove of every group of air channel at a distance of about 8 millimeters.Air channel 8 is arranged to towards cover body the first half.
Between two pairs of parallel slits that extend substantially vertically 11, each group air channel 8 below near the cylindrical wall of cover body 4 bottoms to internal strain.This structure can make flange 12 can be installed on the cover body 4, for cover body provides an external flanges 13 of extending along its openend.This flange 12 comprises a barrel portion 14 and flange 13.This barrel portion 14 fits tightly with the cylinder shape inner wall of cover body, and comprises 2 tongue pieces 15 that along the circumferential direction extend that relatively are arranged on the flange.When tongue piece 15 such arrangements can be rotated at flange 12 insertion cover bodies 4 and with respect to cover body, make tongue piece pass vertically extending slit 11,, thereby be locked in flange 12 on the cover body 4 through the front of the inside crushed element of cover body cylindrical wall.
Flange can be processed with any suitable material, preferable alloy or other suitable fire proofing material.Instantly after illuminator is installed, under ceiling, can see the lower surface of flange 13, so flange 13 optional apparatus are hoped the material of outward appearance to some extent.For example, flange 13 can be processed with brass, perhaps can be gold-plated, chromium plating, perhaps adopts other ornamental paint.Because flange 12 is independent manufacturings with respect to the remainder of cover body 4, flange 12 can be selected different designs as required, and the flange of different outward appearances can be used with the steel cover body of universal design.Although it also is feasible that flange and cover body are integral, with produce flange and cover body all-in-one-piece under illuminator compare, institute's expense of the feasible possible relatively costly decorative material of this design minimizes.
Flange 13 is from the outside radial extension of the cylindrical wall of cover body 4, and the free end of said flange is towards the upwards turnover of its end direction.Like this, flange 13 forms a shallow slot.Said flange is provided with 2 packing rings.Be set directly on the flange 13 is a silicone rubber gasket 16.16 one-tenth steps of packing ring have a thicker zone in outer rim, and inner edge has thin zone.
The inner edge top that rubber washer 16 is thin is provided with an expandable washer 17.This expandable washer 17 comprises cardboard and is coated in the expanding material on the cardboard, for example expandable particle, graphite powder or carbon granule.
Lower edge inner face at flange barrel portion 14 forms a protruding lip 24, and " C " clip 25 with resilience is arranged above protruding lip.
Locate also to be provided with two cavity parts 18 from air channel 8 for 90 ° along the cylindrical wall periphery of illuminator cover body 4 down, cavity part top is provided with support 19 and is used for the elastic force clip 20 that the supporting pivot formula is installed, and this elastic force clip remains on illuminator down in the ceiling panel.These clips have known shape, thereby needn't further describe.
Sealing gasket installing ring 22 is suspended on the steel bar 21 of cavity part 18 inner faces that are fixed in cover body 4 cylindrical walls.There is one to face outer almost circular edge on the said ring, separates with the inner surface of the cylindrical wall of cover body, but substantially parallel.Said edge supports a circular basically flexible gasket 23 with " U " shape cross section, and the sealing pad extends into the space between the inwall of sealing gasket installing ring 22 and cylindrical wall.Sealing gasket 23 usefulness silicon rubber or other suitable material are processed.
A traditional electric connector 26 is installed in outside the cylindrical wall through the support 27 that is fixed in cylindrical wall, and electric wire 7 links to each other with traditional lamp socket 28 from the following illuminator of hole entering that connector 26 passes down the illuminator top.
Under user mode, following illuminator is installed in the hole of ceiling panel 3.Open a circular basically hole 2 on the ceiling panel 3, the size in this hole is just in time held the cylindrical cover body 4 of illuminator down.Elastic force clip 20 upwards rotates on pivot, make said elastic force clip be positioned at cylindrical cover body 4 near, cover body is from bottom to top in the patchhole 2.This makes part elastic force clip 20 sink between cover body 4 and the ceiling panel, and remaining elastic force clip is supported in the top at ceiling panel top, up pushes away cover body 4, thereby flange 13 is compressed to the panel lower surface.This just makes the thicker part of silicone rubber gasket 16 outer rims and the lower surface of ceiling panel 3 compress, and forms the sealing of isolated noise, moisture and other pollutant.
Power supply is connected with electric connector 26 through traditional method.
For in the illuminator lamp 10 being installed down, at first lamp socket 28 is installed on the lamp.Remove " C " clip 25 from flange 12, in the cover body with illuminator under the lamp insertion, and " C " clip 25 is replaced." C " clip 25 keeps lamp 10 to be positioned at illuminator inside down, and lamp and the sealing gasket 23 that is installed on the sealing gasket installing ring 22 are compressed, and between lamp 10 and cylindrical wall inside, forms the sealing of isolated noise, moisture and other pollutant.
When lamp 10 used, the heat that the lamp 10 in the following illuminator cover body 4 produces distributed through air channel 8.Powder coating on cover body 4 is for isolated metal, thereby, make the temperature of cover body outside be lower than the temperature when not using coating.
If breaking out of fire below ceiling panel, the existence of following illuminator can (at least not basically not can) influence the fire line of panel.If fire heating expandable washer 17 reaches certain temperature, expanding material can expand, and between flange 13, following illuminator cover body 4 and ceiling panel 3, forms an effective fire proof seal.This has just blocked flame and smog and has spread passage between illuminator 1 and the ceiling 3 down.
If fire enters into the cover body interior (no matter whether lamp 10 is perfect) of light fixture,, can not spread to the space of panel top through air channel 8 owing to the structure and the size of air channel 8.Air channel 8 is narrow, and its structures shape flame just can throw out light fixture downwards.Can limit the passage of propagation of flame so very significantly.The hole that following illuminator top supply lines 7 passes is enough little, can block any significant propagation of flame passage.
Said light fixture is superior to illuminator under the present fire prevention.The size of air channel and structure can make the light fixture available ventilation, block the passage of fire spread effectively simultaneously, thereby make light fixture can reach the requirement of BS476 the 21st part.These holes are formed at makes in the light fixture process.Need not block the passage that flame spreads through the passage in the light fixture with extra expanding material or other material.This makes cost reduce.
Lamp must be installed an independently sealing gasket before being inserted in the light fixture above lamp, compare with traditional light fixture, and the sealing gasket installing ring greatly helps the installation of light fixture.This independently sealing gasket, an extra difficulty possibly or be left in the basket fully by misloading and not install.This is undesirable.
The above embodiment only is that it all is possible not departing from many variations of the present invention for example.
