1,, when plug LED, breaks the connection lead easily because LED fills in the very big obstruction of existence from top to bottom.

2, also exist a problem not work when keeping in repair indivedual LED occurring when product exactly in addition, normal conditions are to cut clad from the bottom of product with cutter the LED in the heart yearn strip shape body is changed, but the middle part of strip shape body cross section is set when the through hole of placing the connection lead, and the upper side wall of through hole is vertically cut the formation seam, so LED and connection lead can only cut clad and astigmatism body from the product top in this structure, difficulty is very big like this, and easy light-emitting area at product stays scar after the product reparation, influences attractive in appearance.

3, owing to be connected in series by lead between each LED, between LED and the LED by the electric wire welding and connect, then resistance and LED are filled in cannelure with the electric wire that is connected between the LED, the resistance of connecting between LED and the LED is filled in two transverse circular holes that are arranged between transverse holes and the transverse holes, because LED must be greater than the distance of transverse holes and transverse holes with the wire length that is connected between the LED, therefore this connection electric wire is filled in and is circuitous state in the cannelure, so resistance is not placed in more spaces in cannelure, for this reason this technical products in structure transverse holes and transverse holes between be provided with two transverse circular holes and place in the resistance, therefore also increased production process, if cannelure is enlarged in order to place resistance, so will because of each road between the LED and the LED that are placed in the cannelure be connected electric wire between distance increase, the labyrinth that occurs each road connection electric wire so when the product horizontal direction bends is different, thereby cause the section of drawing to connect electric wire, and after if the connection lead that in use connects the resistance one or both ends breaks, can exist two to connect that leads contact and the conducting electric current, so LED will burn not having under the situation of series resistance.

4, since between this LED and LED and the resistance by being connected the electric wire welding, can not weld automatically by mechanization, and need fill in the corresponding transverse holes, thus need be a large amount of when making manually, have the high shortcoming of cost.

Also have same inventor Ben Fan to invent a kind of Chinese patent application number to be: 200420093781.5, the PCT number of patent application is: CN2005/000176, it is the strip shape body of rectangle that name is called the cross section that " a kind of tube lamp improvement " this invention disclosed a kind of predetermined length by the flexiplast extrusion molding, this strip shape body prolongs the through hole that vertical portion within it is provided with a rectangle, many the flexible banded circuit board that is provided with some LED is in the vertical rectangular through-hole that is arranged in this strip shape body, above above-mentioned LED bulb, be provided with the opaque but printing opacity astigmatism body of a milky then, a clad is coated on outside above-mentioned rectangular strip body and the astigmatism body, this clad and above-mentioned astigmatism body are an integral body, though this invention has solved the not anti-bending that foregoing invention exists, the defective that production process is loaded down with trivial details, but there is following shortcoming in this invention:

1, because the LED that is arranged on the flexible banded circuit board in this technology only relies on flexible PCB to fix the spacing of LED and LED, but it is flexible that circuit board is, therefore LED is shifted easily in the bending use, produce two even a plurality of LED and be extruded into together, thereby the uneven defective of product light-emitting line occurs.

2, be in the vertical rectangular through-hole that is arranged in this strip shape body owing to being arranged on flexible banded circuit board in this technology, therefore exist this product not bend at longitudinal direction, particularly break flexible banded circuit board easily, even can not bend when this product needed is wrapped in when using on the pillar.

3, since in this technology the two ends of flexible banded circuit board only be confined to be connected by the copper stranded conductor in the strip shape body that connects lead and rectangle, therefore when the length of every unit hour, and have loaded down with trivial details, the consuming time defect of high cost of operation when needing that all flexible banded circuit boards are connected to copper stranded conductor.

4, be connected the both ends that lead is arranged on every unit because flexible banded circuit board is connected with copper stranded conductor in this technology, because product user in use carries out element length to shear as required, when the spacing between LED and the LED is very little, if when shearing, have deviation will cut off the connection lead slightly, therefore be easy to generate waste product.
