Description

The miniature light pipe support of integrated direct current supply of band elastic interface

Technical field

The utility model relates to the light pipe support, particularly has the miniature light pipe support of integrated direct current supply of elastic interface.

Background technology

The miniature energy-conservation support of T4, T5 of existing market circulation all is the spring leaf contact in fluorescent tube employed structure aspect lamp holder contacts.The contact of this spring leaf has following disadvantage: 1, spring leaf very easily is out of shape and causes lamp pin and spring leaf loose contact, thus the initiation fluorescent tube is not lighted or lamp pin and spring leaf between strike sparks, make lamp works unreliable.2, utilize spring leaf contact, for fluorescent tube is installed, lamp socket must leave a breach, so that the entering of lamp pin.But in case such structure fluorescent tube is installed not in place or spring leaf deformation after, fluorescent tube just might be deviate from from lamp socket, the formation hidden danger.3, owing to the error in length of fluorescent tube and support, in the support of chip architecture of the spring, the lamp pin that can occur more than 80% is local exposed, and this has formed great potential safety hazard again.Above-mentioned several disadvantage is common in the use of miniature support.In addition, the miniature light pipe support that does not still have direct current supply in the market.

Summary of the invention

The purpose of this utility model is intended to overcome the deficiencies in the prior art and a kind of work safety, reliable convenient is provided, can many connection, and the miniature light pipe support of integrated direct current supply of the band elastic interface in energy-conservation and prolonging lamp tube useful life.

The purpose of this utility model is achieved in that

A kind of miniature light pipe support of integrated direct current supply that has elastic interface, comprise support body 9, it is characterized in that front end seat 1 built-in preceding lamp socket 2, preceding lamp socket 2 is built-in with spring 2-1,2-4,2-5 and copper sleeve 2-6,2-7 and telescopic head 2-8 and preceding lamp holder sleeve 2-4, rear end seat 5 built-in tail light sockets 6, tail light socket 6 is built-in with spring 6-3,6-4 and copper sleeve 6-5,6-6 and back light cover for seat 6-7, at support body 9 inner chambers electric push-pull dc-to-ac circuit is set.

---described front end seat 1 bottom patches in preceding pedestal 3, and preceding pedestal 3 bottoms patch in bottom 4.

---seat 5 bottoms, described rear end patch in back pedestal 7, and back pedestal 7 bottoms patch in bottom 8.

---described current feed is recommended the formula inverter circuit, by DC power supply V _CCInput direct voltage, be fed to the centre cap of power transformer T through the inductor L that serves as current source, the L cross-over connection is formed resonant circuit in the capacitor C 1 at the elementary winding of T two ends, R1, R2 and diode D form as the start-up circuit that triggers vibration, the auxiliary winding TP3 of T provides positive feedback, to drive VT1, VT2 alternate conduction.

Fluorescent tube of the present utility model and lamp holder have four contact points, form by built-in spring and copper sleeve, because spring has good longitudinal elasticity, making luminous tube pin remain well and closely with copper sleeve contacts, go deep in the lamp holder owing to lamp pin in addition, lamp holder itself and non-notch, so lamp pin can not come off in lamp holder.Can not occur the local exposed phenomenon of lamp pin yet, thereby overcome the defective of spring leaf contact fully.For making things convenient for the loading and unloading of fluorescent tube, one of two lamp holders in this structure are that spring and lamp holder are all scalable for extension type, and another lamp holder then only has spring to stretch.

In a word, the characteristics of this structure are work safety, reliable, convenient, and can be used for T3, T4, T5 fluorescent tube.

The switch crystalline substance that current feed is recommended in the formula transformer is not managed sine wave output voltage, has less switching loss.Secondary winding TP4 two ends at transformer T produce sine-shaped voltage and are applied on the fluorescent tube.C2, C3 carry out filtering to the residual DC in the interchange after boosting, prolonging lamp tube useful life.For change so that open-circuited load, current feed is recommended the formula inverter still can continuous operation.Current feed recommend the formula inverter except to the switching transistor requirement of withstand voltage than higher, have that circuit is simple, sine wave output and reliability be than advantages such as height.

In a word, this product has novel structure, exquisiteness attractive in appearance, anti-aging, fire-retardant, safe and reliable, characteristics such as the life-span is long.Fluorescent tube adopts T3, T4, T5 tubule footpath rare-earth trichromatic energy saving fluorescent lamp pipe, can many connection between the support, be not subjected to the restriction in space.This product is furnished with the installation hook, uses very conveniently, and installs firmly, is difficult for loosening.Be widely used in the environment of AC-less power such as automobile, train, steamer.Simultaneously, can be used as the dc lighting of wind power generation and family, workshop, the emergency lighting when office has a power failure.
