Abstract

The utility model relates to a structure of a lamp holder for an LED daylight lamp, which comprises metal pins, an insulated pin base and end covers. The metal pins of the LED daylight lamp are directly led out from a circuit board inside a lamp tube, and the insulation between the lamp holder end covers and the metal pins is conducted through the lamp tube and the insulated pin base of the lamp holder, so that the manufacturing procedure of the end covers is simplified. No additional wires are required for connecting the pins and the LED lamp, so as to reduce the raw material consumption and the manufacturing procedures. The pins are always leveled with a luminous surface of the LED lamp, so as to dispense with the procedure for correcting the lamp holder to be leveled with the surface of a lamp body, thereby remarkably improving the production efficiency and reducing the raw material consumption.

Description

A kind of LED fluorescent lamp lamp holder

Technical field:

The utility model relates to a kind of LED fluorescent lamp, relates in particular to a kind of structure of LED fluorescent lamp lamp holder.

Background technology:

Because LED has plurality of advantages such as low energy consumption, high light efficiency, long service life, therefore, the LED illuminating lamp tube replaces traditional fluorescent tube gradually, and begins to be widely used in room lighting.

The main distinction of LED fluorescent tube and traditional fluorescent tube is in fluorescent tube inside pcb board to be set, and pcb board is electrically connected with metal pins.The design principle of LED fluorescent lamp is: the pin distance of positions of its apparent size and metal pins can directly be used the support of original fluorescent lamp from trying one's best and common fluorescent lamp size compatibility.

The metal pins of existing LED fluorescent lamp lamp holder is fixed on the end cap, need with insulating materials both to be isolated between metal pins and the end cap, need the circuit of metal pins with the pcb board of fluorescent tube inside be connected with lead during use, its shortcoming is a complex process, operation is many, and production efficiency is low.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming of existing LED fluorescent lamp lamp holder, provides a kind of technology simple, and operation is few, the design of the LED fluorescent lamp lamp holder that production efficiency is high.

The utility model, comprise metal pins and insulation runners, metal pins is fixedly connected on the two ends of the pcb board that places fluorescent tube, on the insulation runners, be provided with two through holes, metal pins passes the two ends that described through hole is exposed to fluorescent tube, the external diameter of insulation runners and the internal diameter of fluorescent tube adapt, and be fixedly connected on the fluorescent tube, described metal pins can be fixedly connected on the two ends of pcb board by brace, and brace is welded on the electrode of printed circuit board (PCB) of pcb board again.

The utility model can be provided with the groove that is parallel to pcb board in the inboard of insulation runners, and the gross thickness of the width of groove and described pcb board and metal pins adapts.

The utility model can be positioned at the through hole in the outside of insulation runners, is provided with the disjunctor bulge loop; At the two ends of described fluorescent tube, end cap is set respectively, on end cap, be provided with two trepannings that adapt with described bulge loop, the end face of end cap is connected with the fluorescent tube contact, and end cap is fixedlyed connected with the insulation runners.

The utility model, described insulation runners can be fixed or the viscose glue mode is connected on the described fluorescent tube by screw.

The utility model has following advantage:

1, directly metal pins is drawn from the circuit board of fluorescent tube inside, thereby saved part raw material and production process, improved production efficiency.

2, the attaching parts that formed by the die casting of a fire retardant insulating plastics-insulation runners is set between end cap and fluorescent tube, these parts play the anastomosis between fluorescent tube and the end cap on the one hand, on the other hand, metal pins passes the through hole of these parts and the trepanning of end cap directly is exposed to the fluorescent tube outside, make its compact conformation, coupling components need not to install additional insulating materials to having played effect fastening and insulation between lamp base and the end cap between end cap and the pin, save material and operational sequence.

3, directly metal pins is drawn on the circuit board of fluorescent tube inside, need not pin to be connected with circuit board doing the integral installation timing, promptly save material and improved production efficiency again with lead.

4, the lamp holder of this programme connects with end cap by a coupling components, and itself and fluorescent tube coupling part can be fastening with screw, dismantle when making things convenient for maintenance in the future.
