Description
Technical field
The present invention relates to the discharge lamp in the electric primary element, particularly be split type compact fluorescent lamp.
Background technology
At present compact fluorescent lamp is divided into two kinds haply, and a kind of is the fluorescent lamp of integral type, because the life-span of fluorescent tube is shorter relatively, so after fluorescent tube damaged, ballast that can also operate as normal was also scrapped relatively waste thereupon.Also having a kind of is split type fluorescent lamp, and this fluorescent lamp can be changed the fluorescent tube part separately, and ballast can continue to use, and can avoid waste like this.And present split type compact fluorescent lamp mostly adopts the G23 of standard or the jockey of G24 series, this jockey not only volume is big, and in order to plug conveniently, all adopted the metallic spring bayonet socket, make that fluorescent tube and ballast can not be fastening well, even produce loosening, for example 2U fluorescent tube and 3U fluorescent tube or the like, have to jockey the is placed on middle part of ballast, make the volume of ballast become big, add elongated fluorescent tube, it is out of proportion that whole lamp will become, and seems very not attractive in appearance.And for example ZL02269941 " a kind of separated energy-saving lamp " adopts is Elastic buckle formula interconnection technique.
Summary of the invention
The objective of the invention is to design a kind of new split type compact fluorescent lamp, further reduce the volume of lamp, improve ballast and fluorescent tube connection stability, prolong the useful life of fluorescent lamp and improve its result of use.
Technical scheme of the present invention is as follows: a kind of split type compact fluorescent lamp, but this fluorescent lamp comprises clutch independently ballast and fluorescent tube, described ballast is provided with the lamp holder that is electrically connected with the city.Be provided with movable locking device between this fluorescent lamp ballast and the fluorescent tube, this locking device comprises outside visible execution portion, by the sticking department that execution portion extends inward, and also comprises the directed portion of control execution portion movement locus; Described locking device inserts in the set jack of fluorescent tube assembly upper surface, by the control lock bonding part locking of execution portion or unlock, and control ballast and fluorescent tube affixed or separate.
Wherein locking device can comprise at least three kinds of designs, one of them is that directed portion in the described locking device comprises the tubular slideway that is arranged at ballast lower surface middle part and is arranged in the execution portion and is set in sliding sleeve on the slideway, the nozzle limit of described slideway is provided with the annular nib that protrudes from this barrel outer surface, and the bottom of slot is provided with the block that protrudes from barrel outer surface; Described sticking department is included in the longitudinal socket that is provided with on the slideway cylindrical shell, is axially set in hook L shaped on the sliding sleeve, is convexly set in the projection of fluorescent tube jack inner surface.
Second kind of design is exactly: the directed portion in the described locking device comprises and is arranged at fluorescent tube jack inner surface annular slide track and is arranged in the execution portion and is flush-mounted in sliding sleeve in the described slideway that the top of described sliding sleeve is provided with the chimb that protrudes from its outer surface; Described sticking department is included in slot longitudinally is set on the annular slide track; Be axially set in hook L shaped on the sliding sleeve; Be convexly set in the projection of ballast lower surface, the head of this projection is provided with the protrusion of projection, and this protrusion can be located on the stud bumps and also can be located on the tubular projection.The operation principle of this syndeton is just had any different on the structure with above-mentioned a kind of identical.
The third design is: the directed portion in the described locking device comprises and is arranged at the recessed slideway of fluorescent tube or ballast outer surface annular and is arranged in the execution portion and is flush-mounted in sliding sleeve in the described slideway; Described sticking department is included in slot longitudinally is set on the slideway; Be arranged at the slot of outer recessed vertical perforation sliding sleeve on the sliding sleeve; Be convexly set in the projection of ballast lower surface, the head of this projection is provided with the protrusion of projection, and this protrusion can be located on the stud bumps or on the tubular projection.
How to make firm being connected of the permanent maintenance of ballast and fluorescent tube, the scheme that the present invention adopts is that sticking department is provided with hold-down mechanism, and during the locking locking device, this hold-down mechanism pushes ballast or fluorescent tube to the other side, force both closely connected.The concrete structure of this hold-down mechanism can adopt following two kinds: a kind of is elastic construction, a kind of pushing structure.
This split type compact fluorescent lamp described in the invention has following characteristics:
1. be connected compactly between ballast and the fluorescent tube, the volume of fluorescent lamp is less, not only can be used for powerful compact fluorescent lamp, and can be used for low power small compact type fluorescent lamp;
