The specific embodiment

LED fluorescent lamp side view like Fig. 1; The conductive pin 5 that fluorescent lamp end cap 1 is arranged and be connected shown in the figure with end cap 1; Conductive pin 5 is arranged on the end cap 1 for radial symmetric; On end cap 1, also be provided with connecting hole 12, said connecting hole 12 is arranged on the perpendicular bisector of two conductive pins 5 and apart from end cap 1 centre distance and is about the half the of radius.

All directions cutaway view shown in shown in Fig. 2 to 4, being respectively on Fig. 1; The fluorescent lamp of LED shown in the figure also comprises lampshade 2, light circuit plate 3, metal clamshell 4; On light circuit plate 3, be provided with emitting semiconductor 32; In end cap 1, also be provided with conducting strip 6, in the LED fluorescent lamp, also be provided with connector 8.Described conducting strip 6 is electrically connected with conductive pin 5; And conductive pin 5 is fixed on conducting strip 6 in the end cap 1 with the riveted joint form, and between conductive pin 5 riveted joints place and conducting strip 6, also is provided with glass plate 7, and the effect of reinforcing is played in the 7 main effects of glass plate; Because conducting strip is thinner; So adopt thicker glass plate 7 can better play fixation, on conducting strip 6, also be provided with locating hole, in end cap 1, also be provided with protruding 11; Protruding 11 place the locating hole on the conducting strip 6 that conducting strip 6 is not rotated in end cap, avoid making 6 contacts of two conducting strips and cause short circuit.Also be provided with shell fragment 61 on the said conducting strip 6; Shell fragment 61 is connected with 3 contacts of light circuit plate; Electric current is imported on the light circuit plate 3, and said shell fragment 61 is as a whole with conducting strip 6, forms through bending; Shell fragment 61 contacts an end with the light circuit plate and is circular-arc; And shell fragment 61 is pressed on the power access end (being the output of power supply) on the light circuit plate 3, makes contact better like this, and to be arranged to connecting portion circular-arc be for easy to connect; Only need with end cap 1 be buckled in the fluorescent lamp end then shell fragment 61 will closely contact with tube circuit plate 3 smoothly naturally; Because shell fragment 61 is flexible, and contact jaw is circular-arcly like this shell fragment 61 is pressed on the light circuit plate 3 with can having a certain degree with initial position after light circuit plate 3 contact, makes emitting semiconductor 32 luminous thereby conduct electricity to light circuit plate 3.Because conductive pin 5 need be fixed on conducting strip 6 and glass plate 7 in the end cap 1 with the form of riveted joint; So be provided with bulge loop 51 (through machinery equipment punching press distortion) in the place that conductive pin 5 contacts with end cap 1; Described conductive pin 5 is placed when end cap 1 injection moulding together; So bulge loop 51 is stuck in the end cap 1, conductive pin 5 can not make quick and easy for installation owing to stressed excessive coming off yet when doing the riveted joint processing like this.In fluorescent lamp, also be provided with connector 8, described connector 8 links together end cap 1 and tube circuit plate, need not end cap be connected on the fluorescent lamp clamshell like this, from but connect more convenient.Described connector 8 comprises screw hole 81, barrier rib 82 and resilient barb 83; Can be simultaneously with reference to figure 6; Its connected mode is following: the two ends at light circuit plate 3 respectively are provided with buckle slot 31; The resilient barb 83 of connector 8 just in time is buckled in the buckle slot 31, resilient barb 83 be two symmetries have the wedge shape of falling of groove at root, resilient barb 83 snaps in buckle slot 31 processes before this wedge shape of falling of two symmetries and draws close to the centre; Shape is replied in the resilience of falling the wedge shape when root, and the groove on the wedge shape fastens buckle slot 31.End cap 1 and connector 8 are connected through screw, and after at first connector 8 fixed in fluorescent lamp, end cap 1 covered through the 12 usefulness screws of the connecting hole on the end cap 1 and is connected in the screw hole 81 of connector 8.Because connecting hole 2 is all unique with screw hole 81, so better location, location.Set barrier rib 82 on connector; Described barrier rib 82 intercepts shell fragment 61 and opens with metal clamshell 4; So, make fluorescent lamp in use more safe and reliable because connector 8 is that insulating materials can increase power supply like this with the creep age distance between the metal clamshell 4.Said light circuit plate 3 is fixed on the metal clamshell 4, can guarantee that connector 8 is connected with the light circuit plate can not become flexible after connecing.

Be depicted as the cross sectional view of fluorescent lamp shade and metal clamshell like Fig. 7 and 8, lampshade 2 shown in Figure 7 is connected on the metal clamshell 4 whole rounded, and lampshade 2 both sides and metal clamshell 4 junctions respectively are provided with one section bellows segment 21; Said bellows segment 21 mainly plays irreflexive effect, the arc section between the said bellows segment 21 be 110 °～120 ° to the scope of central angle alpha, light is direct projection basically in this scope; So not be used in this scope and establish bellows segment; Described bellows segment 21 is a zigzag, and adjacent two sawtooth, and the angle β between the face is 50 °～53 °;, light on serrated face, will produce refraction when running into bellows segment 21; Circuit through continuous refracted ray changes, thereby makes the illumination range that shines out bigger, makes fluorescent lamp reduce the area of dark space.

To fluorescent lamp internal structure shown in Figure 10, it is divided into two kinds of electric connection mode like Fig. 9, and a kind of is single-ended input; Conduct to conducting strip like Fig. 9 electric current from conductive pin, the conducting strip that electric current flows into end is connected with conductive pin, and does not establish the shell fragment that is connected with light circuit plate 3 on the conducting strip; On conducting strip, be connected with input lead 91, input lead 91 is input to electric current in the power pack 9, and electric current in power pack 9, is divided into reversal through processing and suitable voltage is exported from output lead 92; Conduct on the conducting strip of the other end; Conducting strip is provided with shell fragment here, and is connected with light circuit plate 3, and the conducting strip here is not connected with conductive pin.Another kind is the both-end input; The connected mode at its two ends is the same, and a conductive pin is connected with conducting strip, or directly is connected with input lead 91; Electric current is imported power pack 9; Through the processing of power pack 9, the anodal electric current or the cathodal current of deriving rated voltages from output lead 92, an end on the contrary then derive rated voltage and with the opposite electric current of a relative termination electrode.Output lead 92 is connected with the conducting strip of opposite side, and conducting strip is provided with shell fragment, and shell fragment is connected on the light circuit plate, and the conducting strip that is connected a side with the light circuit plate does not link to each other with corresponding conductive pin.
