Said structure owing to being provided with limited post and spacing ring, has formed draw-in groove, when lamp holder is installed on housing and lampshade, therefore housing and lampshade holding are in draw-in groove,, can realize the accurate location of housing, lampshade and lamp holder, make the location reliable, stable, to guarantee quality and the life-span of LED fluorescent tube.
As improvement, be provided with the rib that is connected with locating ring on end face, described limited post and spacing ring are located on rib.This structure by rib is set, can improve the intensity of lamp holder, simultaneously, can improve the bonding strength of spacing ring and limited post and end.
As improvement, be positioned at draw-in groove and be provided with the blocking part on rib, described blocking part can prevent that housing, lampshade end face from directly contacting with the end, make between housing, lampshade end face and end gapped so that installation and removal lamp holder.
As specializing, described buckle is located on rib; Described buckle comprises connecting portion and snap fit, and an end of connecting portion is connected on rib, and snap fit is located at the other end of connecting portion.
As improvement, connecting portion is provided with more than one groove, and this structure can guarantee the elasticity that is connected between connecting portion and rib, can save material again, thereby reach the purpose that reduces costs.
As improvement, have groove on position corresponding with snap fit on locating ring.After lamp holder was installed on housing, buckle was positioned at housing, the snap fit holding of buckle to bayonet socket, for the ease of the dismounting lamp holder, by groove is set so that snap fit expose.
As improvement, locating ring is provided with an extension.Described extension can increase the contact area of lamp holder and housing, thereby further improves the reliability of positioning of lamp holder and housing.
As improvement, the end face of limited post and the end face of LED light source are inconsistent, with the location LED light source, prevent that LED light source from moving in cavity.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figures 1 to 4, the LED fluorescent tube comprises housing 1, lampshade 2, LED light source 3, power supply 4 and lamp holder 5.
As shown in Figure 4, housing 1 comprises shell 11 and loading plate 12, the cross section of shell 11 is U-shaped, and loading plate 12 is located at the opening part of shell 11, and shell 11 and loading plate 12 are one-body molded, be formed with accommodating cavity between shell 11 and loading plate 12, be provided with the bayonet socket (not shown) on shell, be provided with radiating ribs 13 on the outer wall of shell 11, to improve radiating rate, be positioned on shell 11 loading plate 12 above be provided with the first draw-in groove 14, be formed with the second draw-in groove 15 on shell 11 outer ends.
Be formed with card article 21 on lampshade 2, card article 21 holdings realizing being connected of lampshade 2 and housing 1, and can easily be dismantled lampshade at the second draw-in groove 15.
Described LED light source 3 comprises substrate 31 and LED chip 32, and LED chip 32 is arranged on substrate 31, and the side of substrate 31 is stuck in the first draw-in groove 14, the lower surface of substrate 31 contacts with loading plate, like this, by the mode of holding, LED light source is installed, is convenient to installation and removal, and substrate contacts with loading plate and can increase the speed that heat transmits, thereby the raising radiating effect, simultaneously, substrate 31 is under the support of loading plate 12, can reduce the deflection of substrate 31, thereby improve the light effect that of LED fluorescent tube.
Described power supply 4 is arranged in accommodating cavity.
To shown in Figure 7, lamp holder 5 comprises end 51 and locating ring 52 as Fig. 5, and locating ring 52 is one-body molded with end 51, is provided with extension 53 in an end of locating ring 52, and extension 53 is curved.Being positioned at locating ring 52 on end 51 is provided with and the one-body molded rib 54 of locating ring 52, to improve the intensity of lamp holder, be provided with limited post 55 and spacing ring 56 on rib 54, form draw-in groove 57 between limited post 55 and locating ring 52, spacing ring 56 also forms described draw-in groove 57 with locating ring 52, is positioned at draw-in groove 57 at rib 54 and is provided with blocking part 58; Be connected with buckle 59 on rib 54; Described buckle 59 comprises connecting portion 591 and snap fit 592, and snap fit is located at the other end of connecting portion, and connecting portion is provided with more than one groove 593, to save material, reduces costs; Have groove 510 on position corresponding with snap fit on locating ring.
