CN2143364Y - Rectangular fluorescent tube - Google Patents

Abstract

The utility model discloses a rectangular fluorescent tube, which is characterized in that a lamp tube is bent into a rectangular shape, an opening is arranged in the middle of the long side of the rectangular fluorescent tube, a supporting frame is bunted on the middle parts of the two long sides, and an interface is arranged at the middle part of the supporting frame. The design of the utility model only four 90 deg. Bending angles are adopted, the complexity of the production process can be reduced, the product yield is increased, an attractive appearance is provided, and various fluorescent tubes whose power are 5 to 28w can be produced.

Description

Rectangular fluorescent tube

The utility model relates to the domestic lighting technical field, specifically a kind of rectangle fluorescent tube.

All there are some shortcomings in existing compact fluorescent lamp tube as H type, double H-type, U type, HU type, double-U-shaped, two D type, as the lighting tube production technology complexity, and the junction easy fracture, percent defective is more high.

The purpose of this utility model is to design a kind of production technology fluorescent tube simple, handsome in appearance.

Design of the present utility model comprises fluorescent tube, support and interface, it is characterized in that fluorescent tube curves rectangle, and opening is in the middle of long limit, and support 2 is supported on middle part, two long limits, and interface 3 is installed in support 2 middle parts.

Fluorescent tube according to the utility model design is a rectangle owing to its fluorescent tube, has only four 90 ° bent angle, has reduced the difficulty of bend pipe in the production technology, simplify production technology, do not had 180 ° of bent angles, also do not had the connecting portion of glass tube, and handsome in appearance, the rate of finished products height.

The utility model has following accompanying drawing:

Fig. 1 rectangle fluorescent tube structure schematic diagram

Fig. 2 convex interface schematic diagram

Fig. 3 spill interface schematic diagram

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation, and similar with known pair of D type fluorescent tube, the utility model comprises fluorescent tube 1, support 2 and interface 3.Known pair of D type fluorescent tube has two 90 ° of bent angles and two 180 ° of bent angles, and production technology is complicated; Fluorescent tube 1 of the present utility model curves rectangle, and oblong openings is in the middle of long limit, and two openend spacings are 10～30mm, is best with 20mm.Fluorescent tube 1 adopts the normal diameter glass tube, and pipe range also adopts and power of lamp tube corresponding standard size, can make the various fluorescent tubes of 5W～28W.Owing to have only four 90 ° of bent angles, bent tube technique, sprayed with fluorescent powder technology are all much simple than prior art.

Support 2 of the present utility model is supported on middle part, 1 two long limits of fluorescent tube, can adopt material such as plastics or bakelite, and the part that is connected with openend is just in time blocked blackhead, neither influences illumination, has increased attractive in appearance again.The shape of support, structure are referring to Fig. 1.

Interface 3 of the present utility model can adopt arbitrary interface of the prior art, for example can adopt convex interface shown in Figure 2, also can adopt spill interface shown in Figure 3.Starter can be connected in the interface 3, also matching capacitance can be connected, to be respectively applied for Inductive ballast and electric ballast; Also can be connected with starter and matching capacitance simultaneously, make universal fluorescent tube.

Filament in the utility model fluorescent tube 1 can adopt known standard filament, by known connected mode or do not have the hot filament connected mode and all can.The connection of filament and interface 3 can be with known pair of D type fluorescent tube identical.

Attractive in appearance in order to increase, the ratio of fluorescent tube 1 length of side of support 2 both sides all adopts golden section proportion, half the ratio that is minor face and the long limit of rectangle fluorescent tube 1 is a golden section proportion, this about the general fluorescent lamp of fluorescent lamp moulding formed of two golden section shapes attractive in appearance.
