Abstract

A rotary electrode-changing long-life energy-saving lamp is provided. The utility model belongs to a energy-saving lamp technic field. A plurality of contacts are provided at an inner side of an upper housing of a energy-saving lamp circuit board protection housing, the contacts are contacted with a cathode and an anode of a contact connection circuit board; a plurality of spring plates are provided at an outer side of a recessive inserting interface of a lower housing of the circuit board protection housing, the spring plates are contacted with a cathode and an anode of the lamp and engages the upper housing with the lower housing to make the contacts be point-plate contacted with the spring plates to compose an intact circuit. When an end of the lamp is black, the engaged upper housing and the lower housing are rotated with 180 DEG reversely with each other, to change the point-plate contaction of the contacts and the spring plates, thereby resulting change of the original cathode and anode of the energy-saving lamp to compose a new intact circuit. The utility model has a reasonable structure, easy and convenient to operate, can effectively prolong the life time of the lamp without effecting on an appearance of the lamp.

Description

Rotary pole-changing long-life energy-saving fluorescent tube

Technical field

The utility model relates to a kind of rotary pole-changing long-life energy-saving fluorescent tube, belongs to the power saving fluorescent lamps 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, negative electrode progressively loss owing to the electronics emission, in case 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 the conversion that a kind of upper and lower casing by rotation circuit plate containment vessel is realized negative electrode and anode in the power saving fluorescent lamps, prolongs the useful life of power saving fluorescent lamps, improves the rotary pole-changing long-life energy-saving fluorescent tube of luminous efficiency.

The purpose of this utility model is achieved in that a kind of rotary pole-changing 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; the upper and lower casing that it is characterized in that the circuit board containment vessel is provided with a plurality of contacts and reed, and the contact links to each other with the cathode and anode of circuit board and fluorescent tube respectively with reed.The interface of the upper and lower casing of described circuit board containment vessel comprises and is provided with rotatable latent type and inserts interface structure.Be respectively equipped with on the described upper and lower casing a plurality of contacts and with the same quantity in contact, equidistant reed.

If when setting normal the use, the inboard of the upper shell of circuit board containment vessel is provided with contact B1, B2, B3, B4, and the negative electrode of contact B1, B2 connection circuit plate, the anode of contact B3, B4 connection circuit plate; The latent type of lower house inserts interface arranged outside reed H1, H2, H3, H4, and the distance of reed H1, H2, H3, H4 equates fully with the distance of contact B1, B2, B3, B4, and reed H1, H2 connect the negative electrode of fluorescent tube, and reed H3, H4 connect the anode of fluorescent tube.The upper and lower casing cover is inserted and contact B1, B2 are contacted with reed H1, H2 spot film, contact B3, B4 are contacted with reed H3, H4 spot film, promptly constitute complete loop.When fluorescent tube one end turns black, 180 ° of the upper and lower casing reverse rotations each other that cover can be plugged together, contact B3, B4 are contacted with reed H1, H2 spot film, contact B1, B2 contact with reed H3, H4 spot film, thereby cause the former anode and cathode of power saving fluorescent lamps to change, constitute complete new loop, realize realizing prolonging the power saving fluorescent lamps purpose in useful life by changing the power saving fluorescent lamps anode and cathode.If the position that is provided with of reed and contact is exchanged, also can get same effect.

Latent type inserts interface and also can be arranged on the upper shell of circuit board containment vessel, also can get same effect.

The utility model has the advantages that: 1, only need the circuit board containment vessel structural reform of existing power saving fluorescent lamps is become to be provided with the upper and lower casing that rotatable latent type inserts interface structure, and reed and contact are set, and need not change bare glass fluorescent tube external form and board structure of circuit at interface; 2, rational in infrastructure, easy and simple to handle, effectively prolonging lamp tube service life does not influence fluorescent tube profile effect again.
