The utility aims to provide an LED fluorescence lamp which has a simple structure and rapid dissipating.
Description
[technical field]
The utility model relates to a kind of fluorescent lamp, and a nearly step is said is equipped with the fluorescent lamp of being with the led circuit plate in being.
[background technology]
Fluorescent lamp is a kind of illuminations commonly used, and it is mainly used in room lighting.Along with continuous progress in science and technology and development, with LED (light emitting diode) is that the fluorescent lamp of light source arises, this LED fluorescent lamp is superior to traditional incandescent lamp greatly aspect illumination, yet the LED lamp requires very high to operating ambient temperature, LED is short service life under the hot environment, thereby in the service life that influence is made product by LED, the heat that the LED lamp is produced in use then becomes another problem demanding prompt solution.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, but a kind of LED fluorescent lamp of simple in structure and quick heat radiating is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of LED fluorescent lamp, include fluorescent tube and the plug that is arranged on lamp tube ends, plug is provided with outward extending contact, be provided with the circuit board of band LED in the fluorescent tube, circuit board with link to each other with contact by lead, it is characterized in that described fluorescent tube includes the metal-back that is used for outwards heat radiation and is installed in diffuser on the metal-back, the metal-back outside is provided with and stretches out and the fin of space;
Aforesaid a kind of LED fluorescent lamp is characterized in that described fin is arranged in parallel, and each fin spacing distance is greater than fin thickness;
Aforesaid a kind of LED fluorescent lamp is characterized in that also being provided with on the described fin waveform dimpled grain that is used to increase radiating surface;
Aforesaid a kind of LED fluorescent lamp is characterized in that described metal-back is an aluminium matter;
Aforesaid a kind of LED fluorescent lamp is characterized in that described metal-back inboard is provided with mounting groove, and described circuit board is arranged in the mounting groove;
Aforesaid a kind of LED fluorescent lamp, it is characterized in that described plug is connected by screw lock with the metal-back end, described diffuser is tightly limit vertically between two plugs, the metal-back both sides are respectively equipped with draw-in groove, diffuser two relative edges are respectively equipped with the edge that bends inwards, and two edges can correspondingly insert in two draw-in grooves;
Aforesaid a kind of LED fluorescent lamp is characterized in that described plug side is provided with the annular brace that can be inserted in the described diffuser.
The beneficial effects of the utility model are:
1, metal-back is the aluminium manufacturing, the metal-back inboard is provided with mounting groove, circuit board is placed in the mounting groove, the metal-back outside is provided with the also fin of space that stretches out, each fin spacing distance is greater than fin thickness, also be provided with on the fin simultaneously and be used to increase the waveform dimpled grain of radiating surface because the metal-back good heat conductivity, after lighting heating Deng LED, temperature can be through a plurality of fin quick heat radiatings in the metal-back outside in the fluorescent tube, thereby temperature keeps and the approaching level of the outer temperature of pipe in the assurance fluorescent tube, prevent that LED from damaging because of high temperature, prolonged LED service life;
2, diffuser is stuck in the draw-in groove on the metal-back and tightly limits between two plugs vertically, makes that diffuser is fixed up tightly, and is simple in structure.

Fig. 2 is a fluorescent tube cross section structure schematic diagram;
Fig. 3 is a metal-back cross section structure schematic diagram.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in the figure, a kind of LED fluorescent lamp includes fluorescent tube 11 and is arranged on the plug 12 at fluorescent tube 11 two ends, and plug 12 is provided with outward extending contact 13, is provided with the circuit board 14 of band LED in the fluorescent tube 11, circuit board 14 with link to each other with contact 13 by lead.
Wherein, fluorescent tube 11 includes the metal-back 2 that is used for outwards heat radiation and is installed in diffuser 3 on the metal-back 2.Have open-work 125 on the plug 12, metal-back 2 two ends correspondences have screw 25, plug 12 is connected by screw 4 lockings with metal-back 2 ends, metal-back 2 both sides are respectively equipped with draw-in groove 23,3 liang of relative edges of diffuser are respectively equipped with the edge 33 that bends inwards, two edges 33 can correspondingly insert in two draw-in grooves 23, diffuser 3 can only slide along draw-in groove 23 like this, adding diffuser 3 tightlier limits between two plugs 12 vertically, and plug 12 inboards are provided with the annular brace 120 that can be inserted in the diffuser 3, make that diffuser 3 is fixed up tightly.
In the utility model, metal-back 2 is the aluminium manufacturing, and diffuser is the plastics manufacturing of light-permeable.Metal-back 2 inboards are provided with mounting groove 21, and circuit board 14 is placed in the mounting groove 21, and metal-back 2 outsides are provided with the also fin 22 of space that stretches out, and fin 22 is arranged in parallel.In order to strengthen radiating effect, each fin 22 spacing distance also is provided with the waveform dimpled grain 220 that is used to increase radiating surface on the fin 22 simultaneously greater than fin thickness.During use because metal-back 2 good heat conductivity of aluminium matter, after lighting heating Deng LED, temperature rises in the fluorescent tube 11, metal-back 2 quick heat absorptions make a plurality of fin 22 quick heat radiatings of heat through its outside simultaneously, thereby guarantee that temperature keeps and the approaching level of the outer temperature of pipe in the fluorescent tube 11, prevent that LED from damaging because of high temperature, prolonged LED service life.
