Abstract
The utility model discloses an LED fluorescent lamp, which belongs to the field of the LED illumination, and comprises a lamp tube, and a lamp adapter and a pin, which are arranged on both ends of the lamp tube; a circuit board is arranged inside the lamp tube, and the circuit board is provided with an LED luminous diode, and the circuit board is electrically connected with the pin; and the lamp tube is formed by a tube wall and a reflection heat radiation plate, and the reflection heat radiation plate is provided with lamp holes, and the LED luminous diode is exposed at the lamp tube through the lamp holes. The utility model solves the problems of the prior LED fluorescent lamp that the heat is accumulated inside the lamp tube and is uneasy to be radiated, thus leading to the short service of the LED and unable cleaning of the user.
Description
Technical field
The utility model relates to the LED lighting field, especially relates to a kind of fluorescent lamp.
Background technology
Along with people are more and more higher to the requirement of environmental protection illumination, the LED illuminating lamp tube with plurality of advantages such as low energy consumption, high light efficiency, long service life replaces traditional fluorescent tube gradually, and begins to be widely used in room lighting.
Yet this in the market high-effect green fluorescent tube all is to be enclosed in the fluorescent tube, has two problems, and the use that has influenced this LED light fixture is with universal:
1. accumulation of heat is not easy to come out in fluorescent tube, causes the lost of life of LED;
2. this LED fluorescent lamp in use for some time can be at the inwall absorption dust of fluorescent tube, and the wiping but the user has no way has influenced whole visuality and light transmission.
The utility model content
The purpose of this utility model is to overcome the shortcoming that existing LED fluorescent lamp exists, and a kind of perfect heat-dissipating is provided, and service life is longer, easily wiping, the LED fluorescent lamp of high printing opacity.
The technical solution adopted in the utility model is:
A kind of LED fluorescent lamp comprises the lamp holder and the pin of fluorescent tube and lamp tube ends; Be provided with wiring board in fluorescent tube, be welded with the LED light emitting diode on the wiring board, wiring board and described pin electrically connect; Described fluorescent tube is surrounded jointly by tube wall and reflective heat sink, and reflective heat sink is provided with lamp hole, and described LED light emitting diode exposes to described fluorescent tube by lamp hole.
Preferably, described reflective heat sink, its two ends are connected with the lamp holder of lamp tube ends by a heat sink respectively, and described fluorescent tube is surrounded jointly by reflective heat sink, heat sink and tube wall.
Preferably, described heat sink, it is provided with louvre.
Preferably, be provided with independently power panel, electrically connect, and be fixedly mounted on the heat sink below with described wiring board.
Preferably, described reflective heat sink and heat sink are straight tabular, and described tube wall is circular-arc.
Preferably, described reflective heat sink is fixed on the described wiring board by screw.
Preferably, described reflective heat sink, its material are PC material, plastic board material or metal material.
The beneficial effects of the utility model are:
At first, reflective heat sink can allow the LED light emitting diode expose to fluorescent tube, can make its contact outside air, and a part of heat of LED light emitting diode directly radiation is diffused in the air; Also wiping and safeguard the LED light emitting diode easily simultaneously;
Secondly, lamp tube ends is provided with heat sink with holes, and heat flows to extraneous in the accelerating tube;
Once more, itself can select good heat sink material such as metal etc. for use reflective heat sink, also can loose the heat in the pipe in outside air with the mode of conduction; Power panel and wiring board be in one, and power panel is arranged under the louvre of heat sink, can reduce the influence of power supply heat to the LED life-span;
At last, reflective heat sink itself not only can not influence the emission of light, can also be ray-collecting cover at random.

The specific embodiment
A kind of LED fluorescent lamp as shown in Figure 1, comprises the lamp holder 1 and the pin 6 at fluorescent tube 5 and fluorescent tube 5 two ends.In fluorescent tube 5, be provided with wiring board 7 as shown in Figure 2, be welded with LED light emitting diode 3 on the wiring board 7.Wiring board 7 electrically connects with power panel 8, and power panel 8 electrically connects with described pin 6, and the extraneous power supply that inserts by pin 6 provides operating voltage for LED light emitting diode 3 after power panel 8 carries out the power supply conversion.
Described fluorescent tube 5, as shown in Figures 1 to 4, surround jointly by tube wall and reflective heat sink 4, reflective heat sink 4 is provided with lamp hole, described LED light emitting diode 3 exposes to described fluorescent tube 5 by lamp hole, so, LED light emitting diode 3 can contact with air, and one part heat directly radiation is transmitted in the air.Described lamp hole can be array on reflective heat sink 4 arranges, and arranges along 45 ° of directions as every row 3 (arrangement of lamp hole and the arrangement of LED light emitting diode 3 on wiring board 7 are complementary) such as lamp holes are set.Wherein, the two ends of reflective heat sink 4 can be connected with the lamp holder 1 at fluorescent tube 5 two ends by a heat sink 2 respectively, and promptly described fluorescent tube 5 can be surrounded jointly by reflective heat sink 4, heat sink 2 and tube wall.Wherein, reflective heat sink can be selected PC material, plastic board material or metal material.Reflective heat sink 4 and heat sink 2 can be for straight tabular, and tube wall is traditional circular-arc.
On the described heat sink 2 louvre 21 can be set, as slot or mounting hole, this LED fluorescent lamp can be provided with independently power panel 8, power panel 8 electrically connects with wiring board 7, and be fixedly mounted on louvre 21 under, independently power panel 8 can not be directly transferred on the lamp pearl of LED light emitting diode 3 heat of power panel.Louvre 21 has the cross-ventilation that can allow in the fluorescent tube 5, and with the reflective heat sink 4 that adopts heat sink material or metal material, connect and compose the light-emitting area of LED fluorescent lamp.
The heat sink 2 at wiring board 7 and reflective heat sink 4 two ends is stuck in the draw-in groove of fluorescent tube 5 together, and middle reflective heat sink 4 is fixed on the wiring board 7 by screw 9, has constituted firm structure together.
In addition, above-mentioned embodiment is not to be restricted embodiment of the present utility model, and modification or equivalent deformation that all those skilled in the art are carried out on the basis of flesh and blood of the present utility model all should belong to technology category of the present utility model.
