Abstract
The utility model provides an LED lamp circuit board and tube thereof provided with a heat radiation function, on the circuit board are provided with louvers. The circuit board and tube provided in the utility model has advantages of a good heat radiation function, improvement of the service life of the LED tube, simple structure, and low cost.
Description
Technical field
The utility model belongs to LED lamp field, particularly relates to a kind of wiring board and fluorescent tube of heat radiating LED lamp.
Background technology
LED is the abbreviation of English light emitting diode (light emitting diode), and its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing all around then, plays the effect of protection internal core.The wafer that the core of light emitting diode is made up of p type semiconductor and n type semiconductor has a transition zone between p type semiconductor and n type semiconductor, be called p-n junction.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge the form of unnecessary energy with light, thereby electric energy directly is converted to luminous energy.Its circuit board and power supply etc. can give out certain heat unavoidably in the process of power conversion.And the LED lamp is in the environment of complete closed, and heat distributes to come out.At present, a lot of dual platens of LED lamp support, multi-layer sheet density height, power are big, and heat distributes difficulty.Conventional pcb substrate such as FR4, CEM3 are the non-conductors of heat, layer insulation, and heat distributes and does not go out.Will cause the electronic devices and components high temperature failure like this.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, LED lamp driver plate and fluorescent tube with good heat radiating function.
The utility model provides the heat radiating LED lamp wiring board, comprises wiring board and in the circuit board wick is installed, is offered louvre in the circuit board.Louvre is preferably opened on the wiring board of fluorescent tube near lamp head both sides and fluorescent tube mid portion.Louvre is preferably circle.The quantity of louvre is preferably more than 2.The utility model provides the LED that has above wiring board fluorescent tube simultaneously.
Heat sink provided by the utility model and fluorescent tube possess good heat sinking function, have improved the service life of LED fluorescent tube, and simple in structure, with low cost.
Description of drawings
Fig. 1 is the utility model wiring board right-hand member schematic diagram;
Fig. 2 is the utility model wiring board left end schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.But following description does not constitute any restriction to the protection content only for better understanding technical scheme.
Referring to Fig. 1 and Fig. 2, be the utility model wiring board schematic diagram.Wherein on wiring board 1 wick is installed, and is respectively arranged with several louvres 2 in the both sides of wiring board, louvre 2 is circular, can certainly adopt other any shape that is suitable for dispelling the heat.Louvre equally also can be arranged on the wiring board middle part.
The quantity of louvre should be more than two in principle.Can adjust according to radiating requirements.
This wiring board is arranged on promptly constituted LED fluorescent tube in the LED fluorescent tube with heat sinking function.
Wiring board provided by the utility model and fluorescent tube because of it offers louvre in the circuit board, thereby possess good heat sinking function, have improved the service life of LED fluorescent tube, and simple in structure, with low cost.
