Abstract

The utility model relates to a plain face light emitting florescent lamp which is made by the bending of a glass tube; in order to add a decorative effect of the lighting source, a butterfly-type fluorescent lamp is put forward and is composed of a butterfly-type fluorescent electric discharge tube and a middle lamp cap, and the butterfly-type fluorescent electric discharge tube coating with fluorescent powder is sealed with filament electrodes. The lamp cap is composed of an upper buckle surface and a lower buckle surface, a fixing bracket is arranged on both sides of the lamp cap, and bracket bayonets are arranged on the ends of the bracket; the butterfly-type lamp tube is arranged on the lamp cap by the bracket and the bayonets, the electrodes of the lamp tube are arranged in the middle of the lamp cap, and the lamp tube is eudipleural; a joint which is used for connecting the lamp tube and a ballast is arranged on the lamp cap, and a starter is arranged in the lamp tube. The utility model can be used for the light sources of a table lamp, a wall lamp, a pendent lamp and a ceiling lamp.

Description

Butterfly-type fluorecent lamp

The utility model relates to a kind of economize on electricity flat florescent lamp---butterfly shape low-pressure gas discharging fluorescent lamp.

Present economize on electricity flat florescent lamp has three U, two D, trigonometric sum square.The illumination and decoration weak effect of this its fluorescent tube moulding of class lamp, can not satisfy in the world to the requirement of compact planar light source on interior decoration.

The purpose of the utility model is to provide a kind of fluorescent tube bending process not too complicated, the novel power saving flat florescent lamp of shape such as butterfly.

The utility model is achieved in that

Derby comprises cap part and fluorescent tube part, and wherein, fluorescent tube is the butterfly shape vacuum sealing tube that the filament utmost point is arranged in inner seal in a certain way, and fluorescent tube and lamp holder are fixed by bayonet socket on the lamp holder and support.

Fluorescent tube of the present utility model.Being made into generally that the top both wings are big, the bottom both wings are little, or top, bottom both wings etc., under special circumstances, can being made into also that top is little, the bottom is big, is equal and opposite in direction with a kind of top of specification lamp or the both wings of bottom.The size of derby is changeable, also can decide according to special requirement according to the size of power, and the caliber that only needs to change four wings of butterfly shape or lamp can realize that the glass tube that scribbles fluorescent material can make fluorescent lamp.

For the lamp of different size, the lamp holder of the utility model design can be installed on the universal lamp holder.The utility model lamp holder back side is the limb of electrode outlet line.Two extreme and two interplane cold junction parts of its lamp can lamp holder front portion or rear portion.

The diameter of above-mentioned each fluorescent tube is decided according to the size of power.Be generally φ=10mm～32mm.

The utmost point sealing-in of fluorescent tube can be in the top or the bottom of butterfly shape lamp.Dress starter in according to whether, filament electrode can be with two lead-out wires or four lead-out wires, and its method for sealing is also different because of the difference of fluorescent tube and filament electrode.

The utility model is selected low-pressure mercury vapour discharge lamp for use, then the electric ballast or the Inductive ballast that are complementary of adapted and power of lamp tube.The joint of fluorescent tube termination and ballast adopts the GR8 standard component, and the joint of ballast and power supply can adopt E27 or B22 standard lamp head, and when the utility model was selected glass tube or quartz ampoule for use, lamp holder adopted E27 or B22 standard lamp head.

The utility model has the advantages that: it is flat luminous evenly for derby, light is soft, color rendering good, does not have stroboscopic effect after being equipped with ballast, and the low voltage starting performance is good and power savings is obvious, and is useful to vision protection.The utility model is of many uses, can be equipped with various light fixtures, makes wall lamp, desk lamp, ceiling light and pendent lamp.

Below be description of drawings:

Accompanying drawing 1 is the structural representation of butterfly shape fluorescent lamp.1 is fluorescent tube among the figure, the 2nd, and the filament electrode of fluorescent tube, φ are tube diameters, and H is the beeline of lamp tube ends head, and L1 is the interplane width in top two, and L2 is two interplane middle part width, L3 is the interplane width in bottom two.

Accompanying drawing 2 is a kind of of derby---the fluorescent tube and the lamp holder mounting structure schematic diagram of butterfly shape fluorescent lamp.1 is fluorescent tube among the figure, the 2nd, filament electrode, the 3rd, lamp bracket, the 4th, support bayonet socket, the 5th, cap body, the 6th, the joint of fluorescent tube termination and ballast, lamp holder is selected E27 or B22 standard lamp head for use, 6 selection standard spares are equipped with starter (not marking among the figure) in the lamp, GB8 standard component 6 couples together with electric ballast or Inductive ballast (not marking among the figure).

Further specify embodiment of the present utility model below in conjunction with accompanying drawing:

Get two length L=240mm, diameter phi=13mm scribbles the glass-tube of rare-earth trichromatic fluorescent powder in the pipe.First each involution one end scribbles one of the filament electrode (method for sealing is with general fluorescent lamp sealing-in) of electronics powder then in each sealing-in of the other end, bend to shape shown in the drawings.Each is made a call to a hole about the about 7mm of diameter with fire and is docking together formation discharge tube gap bridge again at electrodeless involution end.L1=170mm wherein, L3=107mm, L2=95mm because the radius of curvature at each position of lamp is constantly to change, does not mark at this so there is way, bends by mould in the actual fabrication process.After butterfly shape fluorescent tube vacuumized, charge into 430Pa left and right sides argon gas behind the electronics powder on the energising decomposition activation filament, and inject 20mg left and right sides mercury, promptly making power is the butterfly shape fluorescent lamp of 18W.Again butterfly shape fluorescent tube is fixed on the lamp holder as shown in Figure 2, promptly is made into butterfly shape fluorescent lamp described in the utility model.If be made into the lamp of other specification, the value or the diameter phi that only need change L1, L2, L3 can realize.

Claims

1, a kind of butterfly shape fluorescent lamp, comprise lamp holder and fluorescent tube part, fluorescent tube has filament electrode in the inside envelope, scribble the vacuum sealing tube of fluorescent material, it is characterized in that lamp holder is made up of two plastics buckle sides up and down, the lamp holder both sides have fixed support, bracket end has the support bayonet socket, butterfly shape fluorescent tube is installed on the lamp holder with fixed support and support bayonet socket, and the lamp tube electrode end is contained in lamp holder middle part, fluorescent tube left-right symmetric; The joint that connects fluorescent tube termination and ballast is housed on the lamp holder; Starter is housed in the fluorescent tube.
