Description

Plane Y-shape energy-saving fluorescent lamp

The utility model relates to illuminating lamp, more specifically relates to the compact high efficiency energy saving fluorescent lamp.

The compact energy-saving fluorescent lamp of prior art has various ways, as PL lamp (H lamp), two D lamp, annular lamp, 3U shape lamp, SL lamp (dual U-shaped lamp) etc.The fluorescent tube of existing H shape fluorescent lamp is formed through side joint by two fluorescence glass-tubes.This lamp is elongated, profile is not attractive in appearance, and particularly in the occasion of high-power (36 watts), fluorescent tube is longer, and is compact inadequately; In addition, this kind lamp is the non-integral type normally, needs external ballast, so use conveniently inadequately, the fluorescent tube of existing pair of D lamp is formed through bending to pair D shapes by fluorescence glass-tube.This lamp sweep fluorescent coating is impaired, and brightness is low, and glass-tube easily turns black, and profile is also not really attractive in appearance, and is difficult for making high power (as 36 watts) type.The fluorescent tube of existing annular lamp bends to annular by a glass-tube that is coated with fluorescent material and forms.The bending technique complexity of this fluorescent tube need Special Equipment, and behind the bend pipe, the brightness of fluorescent material will reduce.Existing 3U shape fluorescent tube is formed by a glass-tube bending that is coated with fluorescent material, and the angle between three U-shapeds is 120 °.This lamp profile symmetry, attractive in appearance, but need bend to three U-shapeds of 120 ° of angles, fluorescent tube sweep have that brightness is low, the problem of glass-tube blackout, also are difficult for making high power type.

The purpose of this utility model is to provide a kind of appearance novel and beautiful, compact conformation, luminous uniform efficient energy-saving fluorescent lamp, and makes this lamp be easy to make the type of higher-wattage.

The utility model comprises lamp bracket that fluorescent tube, fixed lamp tube are used and ballast etc.Fluorescent tube structure as shown in Figure 1, it is made up of three H shape fluorescent tubes of layout symmetry in same plane.So-called H shape fluorescent tube 1 be meant two parallel to each other and close straight tubes 2 and straight tube 3 or be communicated with the fluorescent tube that forms " H " letter shapes near the tube end place by side direction coupling part 4.The pipe end 5 of H shape fluorescent tube and 6 is the cold junction of discharge tube.Two pipes of a H shape fluorescent tube in three H shape fluorescent tubes are communicated with other a pipe curve transition of two H shape fluorescent tubes respectively, and the end of another pipe of two H shape fluorescent tubes has sealed filament electrode 7 and 8 respectively.The lamp bracket of support luminous tube is positioned at the confluce of three H shape fluorescent tubes, and with the filament electrode capping.When lamp in working order the time, between electrode, form a hollow Y shape discharge channel, so this lamp of title is a plane Y shape power saving fluorescent lamp.

The fluorescent tube of above-mentioned shape is by being coated with glass-tube with the narrow emission band fluorescent material of rare earth through the vacuum tight welding with bend and form, fluorescent tube is through vacuumizing, behind the filament cathode decomposition activation, charge into an amount of argon gas, 4～8mg mercury reinjects, be installed in then on the lamp bracket of particular design, Y shape plane successively can fluorescent lamp.

It is the thin glass tube of 12～20mm that fluorescent tube of the present utility model can adopt external diameter.Distance between the H shape fluorescent tube portion bifurcation straight tube 2 and 3 is that 3～5mm is more suitable, and side direction coupling part 6 is 10 ± 2mm for well from this end end distance.

Lamp bracket of the present utility model can be divided into underframe and two parts of putting on the shelf, and both are connected with the eye-splice groove by the elasticity eye-splice, and Y shape fluorescent tube is fixed.Provide two kinds of designs of monolithic devices lamp bracket and non-integral type lamp bracket below.

The monolithic devices lamp bracket is made of with the institute that puts on the shelf underframe.Fig. 2 and Fig. 3 are respectively the front view and the end view of putting on the shelf.The front portion of putting on the shelf is a cylindrical housings that ballast can be installed, and the rear portion is shrunk to the littler hollow cylinder that has syndeton of external diameter, so that be connected with standard lamp head.Put on the shelf lamp holder locating rack 9, electric ballast (or Inductive ballast) alignment pin 10 and 11, the eye-splice 12 of putting on the shelf and fixedlying connected with underframe.Fig. 4 and Fig. 5 are respectively facing of underframe and end view.Underframe has the eye-splice groove 13 of fixedly putting on the shelf with underframe.

Non-integral type lamp bracket is made of with the institute that puts on the shelf that has standard plug the underframe identical with the monolithic devices lamp bracket.That puts on the shelf is shaped as disc.In the underframe and the formed space of putting on the shelf, starter is housed.Fig. 6 and Fig. 7 are facing and end view of putting on the shelf.The eye-splice 15 that electrode pins 14 is arranged in putting on the shelf, put on the shelf and fixedly connected with underframe.Electrode pins is connected with filament electrode, the outer end can with the receptacle accepts that has electric ballast (or Inductive ballast).

Advantage of the present utility model: compact conformation, good looking appearance, luminous even, fluorescent coating is not impaired in the fluorescent tube course of processing, and the light decay of lamp is little, and is easy to make more powerful lamp (for example 36W).

Embodiment: with external diameter is that 12mm, internal diameter are that the inwall of 10mm is coated with several glass-tubes of fluorescent RE powder (many magnesium aluminates fluorescent material and europkium-activated many barium magnesium aluminates fluorescent material that europkium-activated yttrium oxide phosphor, cerium and terbium activate) on demand behind the back cover, bend and welding on proprietary anchor clamps, the discharge channel that constitutes as shown in Figure 1 is the fluorescent tube of hollow Y shape again.Wherein three H shapes of fluorescent tube angle each other is about 120 °, one-tenth center symmetry, the distance between two parallel straight tubes of fluorescent tube H shape part is 4mm, two parallel straight tube side direction junctions and the distance between the back cover pipe end be about 10mm.The length overall of discharge tube is 430mm.Y shape fluorescent tube is through bleeding, behind the cathode filament decomposition activation, charge into the argon gas of about 3 millimetress of mercury and the mercury of 5mg, after the sealed-off.Y shape fluorescent tube finished product is contained on the aforesaid lamp bracket, and the non-integral type Y form height of promptly making the monolithic devices that has ballast or having a standard plug is imitated energy-conservation compact fluorescent lamp.

Fig. 1 is lamp tube structure figure of the present utility model.

Fig. 2 and Fig. 3 are respectively the front view of putting on the shelf and the end view of monolithic devices lamp bracket.

Fig. 4 and Fig. 5 are respectively the front view and the end view of the underframe of monolithic devices lamp bracket.
