Description

A kind of LED high-voltage constant current module is without wire T8 fluorescent tube

Technical field

The utility model belongs to the technical field of LED illuminating lamp, relates to a kind of T8 fluorescent tube of LED light source.

Background technology

T8 fluorescent tube is the one of fluorescent lamp (or claiming fluorescent lamp, light pipe, fluorescent tube), and diameter is 1 inch, about 25 millimeters, belongs to the one of gas-discharge lamp.It uses electric power to activate mercury vapour in argon or neon, forms plasma and sends short wave ultraviolet, makes phosphorus matter send visible fluorescence with illumination.

Traditional T8 fluorescent tube comprises aluminium section bar (pedestal), lampshade, LED, the aluminum base circuit board that fixed L ED making is electrically connected between LED and the constant-current supply of powering for aluminum base circuit board, aluminium section bar pedestal and lampshade fasten and are formed as one shell, light source is welded on aluminum base circuit board and forms light source board, and be arranged in shell, and light source board and aluminium section bar pedestal are combined as a whole by the plug-in type mode of assembling, its concrete structure is as follows: aluminium section bar base bottom dual-side has the two row's draw-in grooves extended along aluminium section bar pedestal, notch is arranged in opposite directions, lamp source plate inserts between two row's draw-in grooves from one end of aluminium section bar pedestal and fixes as one with aluminium section bar pedestal.But, end cap snapping due to the T8 fluorescent tube of these LED light sources is fixed on the two ends of shell, the power supply of aluminum base circuit board is welded to connect by the conductive feet on flexible circuit conductor and end cap, so, once the conductive feet on end cap is damaged, when changing end cap, the power supply flexible circuit conductor of conductive feet and aluminum base circuit board is needed to cut off, just end cap can be taken off, after changing end cap, also to the power lead of aluminum base circuit board be welded on the conductive pin of end cap, waste time and energy, once virtual connection, larger loss can be brought to fluorescent tube.

Utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, there is provided a kind of LED high-voltage constant current module without wire T8 fluorescent tube, flexible circuit conductor is not adopted to be welded to connect between the conductive feet of the end cap of this T8 fluorescent tube and the power supply of aluminum base circuit board, connect simple, connection reliability is effective, no longer produce virtual connection phenomenon, easy to maintenance.

For achieving the above object, technical solution of the present utility model is: a kind of LED high-voltage constant current module, without wire T8 fluorescent tube, comprises aluminium radiator, lampshade, end cap, multiple LED, fixing aluminum-based circuit board, one or two constant-current supply, two the wiring crane span structures be connected with by equally distributed each LED electrical; Aluminium radiator and lampshade fasten and are formed as one shell; Constant-current supply is fixed on the one or both ends of aluminum-based circuit board, and is connected with LED electrical by aluminum-based circuit board, and there is the input and output side of general supply at the two ends of aluminum-based circuit board; There are two draw-in grooves running through total length aluminium radiator the inner, and aluminum-based circuit board is inserted and secured between two draw-in grooves of aluminium radiator; The two ends of shell are fixed with end cap, end cap have conductive feet hole, and conductive feet is fixed in conductive feet hole, has the endoporus matched with conductive pin in conductive feet; Two wiring crane span structures are separately fixed at the two ends of aluminum-based circuit board, and the conductive pin of its inner end is connected with the input and output side of the general supply in aluminum-based circuit board, and the conductive pin of outer end passes through the endoporus of conductive feet, is connected with external power source; The conductive pin of the innner and outer end of wiring crane span structure is structure as a whole.

The outer surface of aluminium radiator described above has fold.Its area of dissipation is large, good heat dissipation effect.

Constant-current supply of the present utility model is fixed in aluminum-based circuit board, not only increases the reliability of electrical connection, and saves the position of the power storehouse left in fluorescent tube, and structure is simple, and volume diminishes relatively.The utility model adopts wiring crane span structure to be connected with external power source by the input and output side of the general supply in aluminum-based circuit board, its being welded to connect without flexible circuit conductor, and the reliability of electrical connection is high; And once end cap or the conductive feet on it are damaged, directly end cap is taken off, need not again flexible circuit conductor be cut off, as long as conductive feet is plugged on the conductive pin of wiring gantry outer end by the end cap changed, flexible circuit conductor need not be welded again, so, replacing end cap is convenient and swift, can not produce virtual connection phenomenon.
