Summary of the invention
The purpose of the utility model provides that a kind of compact conformation is simple, and the life-span is long, and is in light weight not yielding; LED illuminator light-emitting area in the LED fluorescent tube of built-in power safe in utilization, fluorescent tube is big, and bright dipping is even; Light efficiency is high, can directly replace traditional inductance ballast fluorescent lamp pipe, simple installation.
The purpose of the utility model realizes through following technical scheme.
A kind of LED fluorescent tube of built-in power; It is characterized in that: the LED fluorescent tube of said built-in power comprises PC pipe, two lamp holders, main PCB, secondary PCB, LED illuminator, LED driving power components and parts, connector and lamp holder connectors; One end of said main PCB is through the fixing lamp holder of lamp holder connector; The other end of main PCB is fixedly connected with an end of secondary pcb board through connector, and the other end of secondary pcb board is through fixing another lamp holder of lamp holder connector, and the PC pipe is fixed between two lamp holders; Said LED illuminator is installed on the positive of main PCB, secondary PCB and is fixed in the PC pipe, and LED driving power components and parts are installed in the back side of main PCB.
The LED fluorescent tube of said built-in power comprises that also one supports PCB; In the PC pipe, be provided with relative embedded groove; The both sides of main PCB and secondary PCB are installed in the embedded groove in the PC pipe, support PCB and be fixedly connected with the back side of main PCB, secondary PCB, the plate face of support PCB and main PCB, secondary PCB the back side vertical; Secondary PCB is connected with the main PCB circuit through supporting PCB, for being installed in the LED illuminator power supply of secondary PCB.
Fix through the lamp holder fixed screw between said lamp holder connector and main PCB, the lamp holder, accommodate cap nut, fix through the lamp holder fixed screw between lamp holder connector and secondary PCB, the lamp holder, accommodate cap nut at lamp holder fixed screw loam cake at lamp holder fixed screw loam cake.
Said LED driving power components and parts are connected with the electric main line circuit through main PCB, lamp holder.
The utility model compared with prior art has the following advantages:
The utility model is installed the LED illuminator and is formed firm on-deformable " T " font structure with support PCB owing to main PCB and above the secondary PCB; Embed together in the PC pipe; LED driving power components and parts are installed in below the main PCB, and this Compact Design is incorporated into LED power supply and LED illuminator on the same PCB, make that the LED light-emitting area is big and bright dipping is even; The LED fluorescent tube does not have palp exposed metal part thereby does not have the danger of electric shock; Built-in LED power supply is in light weight, can directly replace traditional inductance ballast fluorescent lamp pipe, is fit to very much the LED light fixture and promotes the use of as energy-saving lamp.
