Abstract

The utility model provides an LED lamp tube with a function of dissipating heat, which comprises a lamp wick, a circuit board and a shell, wherein the lamp wick is arranged on the circuit board and is sealed by the shell; the end surfaces on both sides of the shell are provided with air inlets; the tube body part of the shell is provided with heat dissipating holes; and the heat dissipating holes are optimally arranged on both sides of the lamp tube close to a lamp head part and is preferably arranged on the side back to the light. The lamp tube provided by the utility model has excellent function of dissipating the heat, improves the service life of the LED lamp tube and has simple structure and low cost.

Description

A kind of LED fluorescent tube with heat sinking function
Technical field
The utility model belongs to LED lamp field, particularly relates to a kind of LED power saving fluorescent lamps with heat sinking function.
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 fluorescent tube with good heat radiating function.
LED fluorescent tube with heat sinking function provided by the utility model, comprise: wick, wiring board and shell, wherein wick is installed and to be sealed in the circuit board and by shell, offers air admission hole on shell two side ends face, partly offers louvre at the pipe shaft of shell.Louvre is preferably opened at fluorescent tube near the both sides of lamp head, preferably opens back to light one side.Wherein air admission hole is preferably circle, and louvre is preferably strip.The quantity of each side inlet port is preferably 2, and the quantity of louvre is preferably 4 and is evenly distributed in the fluorescent tube both sides.
Fluorescent tube provided by the utility model possesses good heat sinking function, has improved the service life of LED fluorescent tube, and simple in structure, with low cost.
Description of drawings
Fig. 1 is the utility model tube lamp holder end face part schematic diagram;
Fig. 2 is the utility model fluorescent tube lamp body part 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.
Fig. 1 is the utility model tube lamp holder end face part schematic diagram.Wherein fluorescent tube is circular, and fluorescent tube also can be other shape certainly.Fluorescent tube includes the wick and the wiring board (not shown) of shell and the portion of setting within it and sealing.Its end face of the shell of fluorescent tube is provided with pin 1, also offers two air admission holes 2 in addition on end face.Air admission hole be shaped as circle, also can be adjusted into other shape as required.
Be illustrated in figure 2 as the utility model fluorescent tube lamp body part schematic diagram, offer two strip louvres 3 respectively in the pipe shaft part both sides of shell.The quantity of louvre also can be adjusted according to the length of fluorescent tube.Wherein louvre is opened back to light one side.
Fluorescent tube provided by the utility model, because of its cap part has air admission hole, the lamp body partly offers louvre, thereby in the inner formation of lamp body convection current, possesses good heat sinking function, has improved the service life of LED fluorescent tube, and simple in structure, with low cost.
