Description

Lamp tube structure

Technical field

The technology of the relevant a kind of fluorescent tube of the utility model refers to a kind of application alternating-current light emitting diode (AC LED) and diffusion fluorescent tube especially, need not additionally to be provided with vertoro, makes overall structure more simple, and weight is lighter, and the more even lamp tube structure of scattering.

Background technology

Light emitting diode (LED) has characteristics such as power saving, environmental protection, high efficiency, allow it widespread on various products such as traffic sign, 3C commodity, automobile or various light fixtures.But light emitting diode (LED) must be with DC powered, so when practical application, the current converter (or vertoro) of an external massiveness, except the consume of the lifting that causes price and electric power conversion, more can allow the scope of application of light emitting diode (LED) limited.

More because light emitting diode (LED) belongs to semiconductor light sources, so must drive with direct current (DC), therefore and general alternating current (AC) between a converter must be arranged, but the converter volume is big, Heavy Weight, not only increase the conversion of cost, electric power consume is also arranged, can't with therefore the price competition of existing light source, restriction to some extent on range of application and popularization degree all the time.

Therefore, how to create a kind of lamp tube structure, mainly by alternating-current light emitting diode (AC LED), reaching does not need additionally to connect rectifier transformer, so except reducing the impact of energy loss and antistatic, more can make overall structure more frivolous and can promote overall applicability and be worth, will be that the utility model desires actively to disclose part.

The utility model content

Main purpose of the present utility model need not additionally to be provided with vertoro for a kind of lamp tube structure is provided, and makes overall structure lighter, more simple, can reduce cost simultaneously.

Another purpose of the present utility model is for providing a kind of lamp tube structure, can quick heat radiating, and can make light evenly scatter to the external world, and increase the service life relatively and promote practicality.

For reaching above-mentioned purpose, the utility model provides a kind of lamp tube structure, comprises a diffusion fluorescent tube and an alternating-current light emitting diode module.Two free ends of diffusion fluorescent tube are respectively equipped with a Plug Division, and the Plug Division is provided with power supply contact.The alternating-current light emitting diode module is arranged at the side in the diffusion fluorescent tube, wherein, the alternating-current light emitting diode module comprises a strip heat-radiating substrate and a strip alternating-current light emitting diode (AC LED), and strip alternating-current light emitting diode (AC LED) is arranged at the surface of strip heat-radiating substrate.

In a preferred embodiment, the bottom surface of strip heat-radiating substrate is exposed outside.And the strip heat-radiating substrate is an aluminium base.

Compared to prior art, the lamp tube structure of the present utility model mainly side in the diffusion fluorescent tube is provided with the strip heat-radiating substrate, and the surface of strip heat-radiating substrate is provided with strip alternating-current light emitting diode (AC LED), and diffusion fluorescent tube two ends are provided with the Plug Division, by this, make integral body that vertoro need not be set, the chamber electricity of can directly pegging graft uses, so can not only simplify overall structure, more can promote overall utility.And seeing through exposed strip heat-radiating substrate more can quick heat radiating, increases the service life, and makes light uniform and stable, promotes overall utility.

The specific embodiment

Below by particular specific embodiment embodiment of the present utility model is described, the person skilled in the art can understand other advantage of the present utility model and effect easily by the content that this specification disclosed.

The graphic explanation of following reference embodiment of the present utility model, it should be noted, below graphic for the signal of simplifying graphic, and basic conception of the present utility model only is described in a schematic way, but only the illustration structure relevant with the utility model but not component number, shape and size when implementing according to reality are drawn in graphic, kenel, quantity and the ratio of each element are not to exceed with diagram during its actual implements, and can need change according to actual design, close chat earlier bright.

At first, see also Fig. 1, Fig. 2 and shown in Figure 3, be the side cutaway view of the A-A line segment of three-dimensional exploded view, stereo appearance figure and Fig. 2 of one preferred embodiment of the utility model lamp tube structure.As shown in the figure, lamp tube structure 1 of the present utility model includes a diffusion fluorescent tube 11 and an alternating-current light emitting diode module 12.

Diffusion fluorescent tube 11 has the tube wall of a circular arc type, and the outside, two ends of diffusion fluorescent tube 11 is respectively equipped with a Plug Division 110, and Plug Division 110 is provided with power supply contact 111.

Alternating-current light emitting diode module 12 comprises a strip heat-radiating substrate 121 and a strip alternating-current light emitting diode (AC LED) 122, and strip alternating-current light emitting diode (AC LED) 122 is arranged at the surface of strip heat-radiating substrate 121.The length of the corresponding diffusion of the length of strip heat-radiating substrate 121 fluorescent tube 11, and strip heat-radiating substrate 121 is arranged at a lateral margin of diffusion fluorescent tube 11.

In the present embodiment, strip heat-radiating substrate 121 can be aluminium base, is not as limit certainly, also can be the substrate of other material in other embodiments, and strip heat-radiating substrate 121 bottom surfaces are exposed outside, by this to promote radiating efficiency.

The Plug Division 110 that directly will spread fluorescent tube 11 two ends when reality is implemented directly is plugged on the indoor lamp socket (not shown), make be positioned at both sides power supply contact 111 directly with lamp socket on the contact electric connection, can make the strip alternating-current light emitting diode (AC LED) 122 that is arranged in the diffusion fluorescent tube 11 produce light, and see through diffusion fluorescent tube 11 and make light evenly scatter to the external world, with obvious lifting brightness of illumination.And,,,, reach the purpose of quick heat radiating fast alternating-current light emitting diode (AC LED) 122 hot types that produced are removed so can carry out heat exchange with air immediately because the bottom of strip heat-radiating substrate 121 is to expose outside.

Compared to existing structure, the utility model lamp tube structure is mainly by the setting of alternating-current light emitting diode (AC LED), make overall structure need not could use as the existing structure current converter (or vertoro) of need arranging in pairs or groups again, thus obviously simplified structure, reduce weight and cost.More can cooperate the diffusion fluorescent tube to make light scattering uniformly, so can guarantee the stable and homogeneous and bright of light because of the position that is provided with of alternating-current light emitting diode (AC LED).Moreover strip heat-radiating substrate bottom surface is exposed more to promote radiating efficiency outside.Therefore, except promoting the practicality, more can increase the service life.
