Abstract

The utility model relates to a novel long-life and energy-saving lamp tube, wherein a two-phase convertible switch which is composed of a movable slide block B and a fixed block C is arranged on a protective casing for a circuit board of an ordinary energy-saving lamp. The eight contact points of the fixed block C of the two-phase convertible switch are connected with a negative and a positive poles of the lamp tube through eight reeds. After using the energy-saving lamp tube for a period of time or finding that the negative pole of the lamp tube begins to turn black, the user can switch the two-phase convertible switch on the protective casing for the circuit board. The movable slide block B is pushed and inserted below the eight reeds, and the movable slide block B is covered on the fixed block C. The eight points of the movable slide block B are completely lapped with the eight points of the fixed block C, and the original current passage is changed. Counter rotation between the negative and the positive poles of the lamp tube is realized.

Description

Novel long-life energy-saving fluorescent tube

Technical field

The utility model relates to a kind of novel long-life energy-saving fluorescent tube, belongs to the electricity-saving lamp technical field.

Background technology

Existing power saving fluorescent lamps is made up of glass lamp, circuit board and shell on the current market, and circuit board is placed in the shell.No matter the lamp interface is the socket type or the power saving fluorescent lamps of screw type, its electrode relative fixed, because the lighting theory of electricity-saving lamp is to produce light by the fluorescent material in the cathode emission electron excitation power saving fluorescent lamps, after using for a long time, in case negative electrode progressively loss owing to the electronics emission is after the negative electrode loss, owing to can't carry out the electronics emission and form complete loops makes fluorescent tube turn black, influence the useful life of illuminating effect and fluorescent tube, often promptly accuse and scrap at the negative electrode back fluorescent tube that turns black fully.But,, scrap whole fluorescent tube and promptly formed waste virtually, cause damage to the user because anode, circuit board, the fluorescent material of power saving fluorescent lamps are often still intact at this moment.

The utility model content

The purpose of this utility model provides a kind of conversion by negative electrode and anode in the control power saving fluorescent lamps, prolongs the useful life of power saving fluorescent lamps, improves the novel long-life energy-saving fluorescent tube of luminous efficiency.

The purpose of this utility model is achieved in that a kind of novel long-life energy-saving fluorescent tube comprises glass lamp, circuit board, circuit board containment vessel, lamp interface, lamp tail contact; circuit board is placed in the circuit board containment vessel; it is characterized in that the circuit board containment vessel is provided with the fixed block C that contains a plurality of contacts, reed and be connected lead and contains a plurality of contacts and be connected the convertible switch of two-phase that the removable slide block B of lead constitutes, and the reed among the fixed block C of the convertible switch of two-phase is covered on the contact and with the cathode and anode of fluorescent tube and links to each other.The fixed block C of the convertible switch of described two-phase be provided with a plurality of contacts and with the same quantity in contact, equidistant reed, reed is covered on the contact, connects by lead between the contact.The removable slide block B of the convertible switch of described two-phase be provided with fixed block C go up same quantity, equidistant, etc. the contact of size, connect by lead between the contact.

On fixed block C, one end of H1, H2, H3, H4, H5, H6, H7, eight reeds of H8 is fixed on the fixed block C, its H1, H2 connect the negative electrode of fluorescent tube, the negative electrode of H5, H6 connection circuit plate, and H3, H4 connect the anode of fluorescent tube, the anode of H7, H8 connection circuit plate, the other end of eight reeds then cover respectively on C1, C2, C3, C4, C5, C6, eight contacts of C7, C8.Be connected with lead D1 between C1 and C5, be connected with lead D2 between C2 and C6, be connected with lead D3 between C3 and C7, be connected with lead D4 between C4 and C8, form a complete loop.On removable slide block B, be connected with lead D5 between B1 and B7, be connected with lead D6 between B2 and B8, be connected with lead D7 between B3 and B5, be connected with lead D8 between B4 and B6.During normal the use, removable slide block B is moved apart fully each contact of fixed block C.When fluorescent tube one end turns black, removable slide block B can be moved and be inserted under eight reeds and cover fixed block C.Because the B1 of removable slide block B, B2, B3, B4, B5, B6, B7, C1 among eight contacts of B8 and the stator C, C2, C3, C4, C5, C6, C7, the distance of eight contacts of C8, size is equal fully, after passing removable slide block B, make B1, B2, B3, B4, B5, B6, B7, C1 among eight contacts of B8 and the stator C, C2, C3, C4, C5, C6, C7, eight contact positions of C8 are corresponding respectively to be overlapped, each contact on the removable slide block B after the coincidence substitutes fixed block C and upward contacts with reed each contact, blocked lead D1, D2, D3, the passage of D4, make electric current from lead D5, D6, D7, pass through among the D8, thereby cause the former anode and cathode of power saving fluorescent lamps to change, form another complete loop, realize realizing prolonging the power saving fluorescent lamps purpose in useful life by regulating the power saving fluorescent lamps anode and cathode.

The utility model has the advantages that: 1, only needing increases the convertible switch of two-phase on the circuit board protection housing of existing power saving fluorescent lamps, and does not change bare glass fluorescent tube external form and board structure of circuit; 2, rational in infrastructure, easy and simple to handle, effectively prolonging lamp tube service life does not influence fluorescent tube profile effect again.
