Description

A kind of LED fluorescent tube

Technical field

The utility model relates to a kind of LED fluorescent tube, but relates in particular to a kind of LED fluorescent tube of driving power plug.

Background technology

The LED lamp is so that its efficient is high, energy consumption is low, the life-span is long, volume is little, the characteristics of easy care are widely used in each illumination occasion; Be that the whole world has one of new and high technology direction of development prospect most now; Existing LED can reach more than 50000 hours service life, and the average life span of driving power that electric energy is provided for this LED is then about 10000 hours, just because of the not matching property on this service life; Cause life-span of LED lamp often to depend on the service life of driving power; And if want continue to use the LED lamp, just must repeatedly change, but owing to most of LED lamp driving power sources all are welded on lamp body inside; The inconvenience of having given more tape swapping, but also need replacing person to possess certain professional technique and equipment.

The utility model content

To above-mentioned technological deficiency, the utility model technical problem to be solved provide a kind of simple in structure, volume is little, replacing is easy to maintenance, the split type LED fluorescent tube of plug and play.

In order to solve the problems of the technologies described above; The utility model is taked following technical scheme: a kind of LED fluorescent tube; Comprise lamp body, be symmetricly set in the plug and the driving power at lamp body two ends, an end and the lamp body of plug connect, and the other end is provided with the electrode that is used to connect external power supply and driving power; Said driving power assigns in the groove that plug is complementary, but forms the split-type structural of plug.

Further, said plug is provided with the circuit output end of driving power is complementary and is electrically connected slot, is provided with contact flat spring in this electrical connection slot, and this contact flat spring is electrically connected with lamp body and driving power.

Further, said lamp body comprises that cross section is semicircular lampshade and radiator, and this lampshade and radiator fasten each other and form the cylindrical, hollow cavity, are provided with substrate in the cavity.

Further, said radiator both sides are provided with the V-arrangement gathering sill that matches with the guided way of lampshade.

Further, said plug bilateral symmetry is provided with the concave arc shape handle slot that makes things convenient for the plug driving power.

The utility model compared with prior art; But driving power through the design plug; Realize the driving module and the split design of light source module of LED fluorescent tube, simple and beautiful structure, combination be reliable, change and conveniently need not the specialty maintenance, simultaneously; Because driving power is placed on lamp tube ends, all has very positive effect for problems such as reducing lamp hole temperature, prolongation driving power life-span and solution driving power size.

Accompanying drawing 1 is the utility model surface structure sketch map;

Accompanying drawing 2 is blast structural representations of the utility model one end;

Accompanying drawing 3 is A place enlarged diagrams of accompanying drawing 2.

Label is depicted as among the figure, the 1-lamp body; The 2-lampshade; The 3-driving power; The 4-electrode; The 5-plug; The 6-contact flat spring; The 7-plug; 8-is electrically connected draw-in groove; The 9-radiator; The 10-substrate; The 11-handle slot; The 12-gathering sill; The 13-guided way; The 14-groove.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.

A kind of LED fluorescent tube shown in Fig. 1 to 3; Comprise lamp body 1, be symmetricly set in the plug 7 and the driving power 3 at lamp body 1 two ends; One end and the lamp body 1 of plug 7 connect; The other end is provided with the electrode 4 that is used to connect external power supply and driving power 3, and said driving power 3 assigns in the groove 14 that plug 7 is complementary, but forms the split-type structural of plug.

Said plug 7 is provided with the circuit output end of driving power 3 is complementary and is electrically connected slot 8, is provided with contact flat spring 6 in this electrical connection slot 8, and this contact flat spring 6 is electrically connected with lamp body 1 and driving power 3.

Said lamp body 1 comprises that cross section is semicircular lampshade 2 and radiator 9, and this lampshade 2 fastens each other with radiator 9 and forms the cylindrical, hollow cavity, is provided with substrate 10 in the cavity, and lamp body 1 two ends and plug 7 connect, and fastening with screw.

The accumulation of heat of LED fluorescent tube not only influences the electric property of LED, also possibly finally cause LED to lose efficacy, in order to guarantee the life-span of LED lamp; Heat radiation becomes key technologies for application; Reduce accumulation of heat and become the matter of utmost importance of LED aspect Application Design, therefore, the radiator 9 of LED fluorescent tube adopts quality light in the present embodiment; The Aluminium Radiator that heat dispersion is excellent, the heat that produces in the LED lamp luminescence that effectively the dissipates process.

Substrate 10 adopts aluminium base, possesses good thermal conductivity.

Said radiator 9 both sides are provided with the V-arrangement gathering sill 12 that matches with the guided way 13 of lampshade 2, during use the guided way 13 of lampshade 2 are inserted from the gathering sill 12 of radiator 9 one ends to get final product, and are convenient and reliable, difficult drop-off.

Said plug 7 bilateral symmetry are provided with the concave arc shape handle slot 11 that makes things convenient for plug driving power 3, make things convenient for extracting and inserting of driving power 3.

During use, driving power 3 is inserted in plug 7 corresponding grooves 14, and the output of driving power 3 is inserted in the electrical connection draw-in groove 8; Then the plug 5 with LED lamp tube electrode 4 inserts in the external electric supply socket, realizes illumination, and breaking down like driving power 3 needs to change; Powered-down; The driving power 3 that needs are changed is extracted from plug 7, inserted new driving power 3 again and get final product, whole process is simple, safe, convenient, fast; Need not any professional skill and professional equipment, strengthen user's use confidence greatly.

Because of driving power 3 is placed on the two ends of LED fluorescent tube, to compare with the embedding structure of present routine, heat dispersion greatly improves, and good facilitation is played in protection and the normal use that prolongs driving power 3, also can solve the dimensional problem of power supply simultaneously.
