Abstract

The utility model relates to a thin energy saving fluorescent lamp tube, particularly a thin type and multiple ring shape energy saving fluorescent lamp tube. The utility model is composed of a ring shape lamp tube with 2 to 5 rings and two lamp filaments positioned at the both ends of the lamp tube. The ratio of the length of the long arc tube of the lamp tube and the tube diameter of the lamp tube is 90 to 150. The connection of every ring shape lamp tube can adopt an H shape, a U shape or a pi shape. Thus, the utility model has the advantages of reasonable structure, convenient commercial production, high brightness, uniform luminescence, relatively great power, thin and flat outer appearance, beautiful appearance, etc. The utility model is a novel lamp fixture which is suitable for factories, mines, offices, hotels, families, and schools.

Description

Slim energy-saving fluorescent lamp

The utility model relates to a kind of fluorescent tube, especially a kind of extra-thin energy-saving fluorescent lamp.

In recent years, for making the fluorescent lamp miniaturization, and keep the characteristics of high light efficiency, developed the glimmering fluorescent tube of various types of compacts.For example: 2D type, 3 U types, H type etc.And it is that the fluorescent tube arrangement is compact that the someone designs plane four its advantages of U type compact fluorescent tube (number of patent application 91217031.X), external form novelty etc.But because the fluorescent tube arrangement is compact.Therefore the brightness between the fluorescent tube is obstructed inevitably mutually, thereby also can influence the luminous flux of fluorescent tube, and under some occasion, it is too thick that the thickness of this fluorescent tube is also owed.

The purpose of this utility model provide a kind of luminous evenly, slim energy-saving fluorescent lamp that brightness is high, handsome in appearance.

The utility model mainly is to adopt ring shaped lamp, and its number of rings is 2～5 rings; And total arc length L of fluorescent tube and caliber D) ratio be 90～150, its preferable ratio is 110～130.The power of fluorescent tube generally can be 30～60W.Described ring shaped lamp can be the gradually open arc line of uniform pitch; Also can be to adopt H type, U type, ∏ type, HU type between the fluorescent tube of each ring-like or circular arc type and similarly connect, and can be as required, make planar shaped, also can be coated with last layer high-efficiency fluorescence powder or each ring is coated different color phosphors, send beautiful colorful radiance at the inwall of fluorescent tube.

Fluorescent tube generally can be bent as required by the exposed conduit of φ 8～16mm and form.Inwall can be coated red, yellow, white, green, blue, purple isochrome, is whole monochrome or segmentation color matching shape.

Fig. 1 is a kind of main TV structure schematic diagram of the present utility model.

Fig. 2 is the main TV structure schematic diagram behind a kind of the utility model band lampshade.

Fig. 3 is the A-A cut-away view of Fig. 2.

Embodiment 1: select for use the DB-416 frit of φ 12 ± 0.5mm to make exposed conduit, be coated with one deck three primary colors high-efficiency fluorescence powder within it on the wall, behind roasted tube, tube cell is cut into three sections by required size, and with the filament (5) of 50W respectively with an end closure of fluorescent tube (2a) and fluorescent tube (2c), the other end is fired into flat-top respectively; Flat-top is all burnt till at the two ends of the fluorescent tube of moderate-length (2b).Respectively above-mentioned three pipes are bent into three C type endless tubes (shown in accompanying drawing 1) of required curvature again with mould,, three endless tubes are linked into an integrated entity by common bridging process.In order to improve each annular lamp tube (2) intensity to each other, therebetween except connecing of communicating of tubulose bridge (7) connects, also can be by glass tube or glass bar at the bonding disjunctor (6) of making in the two ends and middle part of each annular lamp tube.Treat the air in the pump drainage pipe, and charge into an amount of mercury and hydrogen that after seasoned, this too many levels can be lighted by build-up of luminance by fluorescent lamp in the electron rectifier circuit that adapts with it.The total arc length L of this fluorescent tube is about 116 with fluorescent tube through the ratio of D, and fluorescent tube external diameter 200mm, thickness are less than 20mm, and interior, the lamp body gross thickness is about 30mm together with lampshade.

Embodiment 2: ultrathin electron rectifier (13) is fixing by the fixed support (12) of being located at lampshade (9) center, and central portion is provided with cosmetic sheet (10) under it; And the below between carefully thin each ring of shape three ring fluorescent tubes (2) is provided with the fluorescent tube fixed card of being made up of supporting seat (8) and fluorescent tube bayonet socket (8a) provided thereon.It is to adopt plastic injection-moulded forming, to improve the intensity of fluorescent tube.Side-lower in the lampshade one is provided with the connection-peg (11) (shown in accompanying drawing 2) of lamp body.

Therefore, the utlity model has rational in infrastructure, luminous evenly, the brightness height, power is big, Cost is low, and conservation is convenient to suitability for industrialized production; And flat thin, attractive in appearance, the practicality of external form etc. Characteristics are a kind of industrial and mineral, office, hotel, family, schools of being widely used in, especially The novel ultra-thin type, the low-pressure energy-saving fluorescent lighting fixture that are suitable for the occasions such as setting height(from bottom) is restricted.

Claims (4)

1, a kind of by ring shaped lamp and be located at the slim energy-saving fluorescent lamp that the filament at its two ends is formed, the number of rings that it is characterized in that described ring shaped lamp (2) is 2～5 rings; And the ratio of total arc length L of fluorescent tube (2) and caliber D is 90～150.

2, slim energy-saving fluorescent lamp as claimed in claim 1 is characterized in that the total arc length L of fluorescent tube (2) and the preferred values of the ratio of caliber D are 110～130, and its power is 30～60W.
