Abstract
The utility model discloses an LED lamp tube. The LED lamp tube comprises a tube body and an LED light-emitting light source arranged in the tube body, wherein lamp caps with pins are arranged on both ends of the tube body; and a clamp ring base is arranged at the middle part of the tube body. The LED lamp tube can prevent the shake of the tube relative to trains so as to prevent the lamp tube from being damaged or dropping from lamp holder. In addition, the LED lamp tube can emit uniform and stable light spots so as to improve the illumination quality in the train.
Description
Technical field
The utility model relates to the LED fluorescent tube in the LED fluorescent tube, particularly track train.
Background technology
LED is because of luminous efficiency height, energy saving; Life-span is long, can realize long-term freedom from repairs, and is not mercurous, pollution-free, environmental protection, and reference color temperature is wide, and adjustable brightness is convenient to build the dynamic space illuminating effect, can satisfy different illumination needs simultaneously, no ultra-violet radiation, DC driven, safe and reliable being widely used.But LED is a heat-sensitive device, and the quality of heat radiation situation directly affects the photochromic stability of fluorescent tube.The hundreds of LEDs heat that sends of working simultaneously is more, can soften pcb board, so the light decay of fluorescent tube is to be difficult to control.For this reason, some occur and improved the LED fluorescent tube of radiating effect, as China Patent No. is to be to be to disclose a kind of LED illuminating lamp tube in the patent documentation of 2010.3.31 2009.5.21 Granted publication day 200920120422.7 applyings date, the body that forms by lampshade and fastener of radiator that comprises hollow, the body two ends are provided with the fluorescent tube termination that is used for closed tube, the fluorescent tube termination is provided with the fluorescent tube pin, body inside is provided with the aluminium base that is fixed on the radiator, be welded with some LED on the inscription substrate, described radiator inner hollow, cavity inside is provided with driving power, and the input of driving power is connected with aluminium base with the fluorescent tube pin respectively with output.Though the LED fluorescent tube of this structure is provided with radiator, the area of dissipation of radiator is little, and therefore, radiating effect is relatively poor; In addition, the LED fluorescent tube is installed on the support by pin, and the weight of LED fluorescent tube is supported by pin, when on the train that LED Alto pipe is installed to motion, train can produce vibration when switching tracks, under action of inertia, and the vibration of LED lamp tube ends following train, and the middle part of LED fluorescent tube can not synchronous vibration, therefore, the LED fluorescent tube is easier to damage, or comes off from lamp bracket, and can also cause the vibration of hot spot, influence the lighting quality of train inside.
Summary of the invention
The purpose of this utility model provides a kind of LED fluorescent tube, and technical problem to be solved is to prevent that the LED fluorescent tube from shaking with respect to train.
For achieving the above object, a kind of LED fluorescent tube comprises body, is located at the LED illuminating source in the body, and the two ends of body are provided with tube head, and tube head is provided with pin; The middle part of body is provided with the snap ring seat.
Owing to be provided with the snap ring seat, by the snap ring seat that the middle part of LED fluorescent tube is fixing ON TRAINS, like this, when train has vibration, the vibration of LED lamp tube ends following train, the middle part of LED fluorescent tube also can synchronous vibration, and like this, the whole LED fluorescent tube is not shaken with respect to train, the LED fluorescent tube is not easy to damage, or come off from lamp bracket, and the hot spot that emits evenly, stable, the lighting quality of train inside is good.
As specializing, the snap ring seat comprises snap ring and is located at the pedestal of snap ring both sides that pedestal is provided with installing hole.The snap ring seat is set, and body is set on the snap ring seat firm; Pedestal and installing hole are set, are convenient to snap ring is installed on the train.
As specializing, described body comprises radiator and lampshade, and radiator and lampshade are interlocked; Radiator comprises installing plate and the fin that is located on the installing plate, and the cross section that all fin constituted is a circular arc.The cross section that all fin constituted is a circular arc, and area of dissipation is big, good heat dissipation effect.
As improvement, the fastening place of radiator and lampshade is provided with draw-in groove, and the fastening place of lampshade and radiator is provided with buckle, and the buckle holding is in draw-in groove.Adopt buckle, draw-in groove structure, be convenient to mount and dismount lampshade.
As specializing, the LED illuminating source comprises aluminium base and led chip, and aluminium base is located on the installing plate, and led chip is welded on the aluminium base.
As improvement, snap ring seat and body are structure as a whole.Adopt integrative-structure, being connected firmly of snap ring and body.

Fig. 2 is the exploded view of LED fluorescent tube.
Fig. 3 is an A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
LED fluorescent tube as shown in Figure 1 to Figure 3 comprises by lampshade 1 and radiator 2 fastening the body that forms that the two ends of body are equipped with tube head 3, and pin 4 is installed on the tube head 3.As shown in Figures 2 and 3, radiator 2 comprises installing plate 21 and the fin 22 that is located on the installing plate, and the cross section that all fin constituted is a circular arc, and like this, area of dissipation is big, good heat dissipation effect.The fastening place of radiator and lampshade is provided with draw-in groove 5, and the fastening place of lampshade and radiator is provided with buckle 6, and buckle 6 holdings are in draw-in groove 5, so that the installation and removal lampshade.Described body is a hollow tube, is positioned at body on installing plate 22 aluminium base 7 is installed, and is welded with led chip 8 on the aluminium base 7.
The middle part of body is provided with snap ring seat 9, and snap ring seat 9 comprises snap ring 91 and be located at the pedestal 92 of snap ring both sides that pedestal 92 is provided with installing hole 93.
When using the LED fluorescent tube, at first pin 4 is inserted on the lamp bracket, with the two ends of fixed L ED fluorescent tube, and electrically connect, then, snap ring seat 9 is installed on the train, and the middle part holding that makes the LED fluorescent tube is on snap ring 91 by installing hole.When train produces vibration in motion, the vibration of LED lamp tube ends following train, the middle part of LED fluorescent tube also can synchronous vibration, like this, the whole LED fluorescent tube is not shaken with respect to train, and the LED fluorescent tube is not easy to damage, or comes off from lamp bracket, and the hot spot that emits is even, stable, and the lighting quality of train inside is good.
