Abstract

The invention relates to an LED (light-emitting diode) lamp tube capable of improving lighting brightness, which comprises a heat radiation base, an LED luminous module, a light-transmitting cover body and at least one voltage transformation element, wherein the heat radiation base is provided with a top plate and an arc-shaped plate positioned below the top plate, an accommodating space is formed, and oblique reflecting plates are formed on two sides of the top plate respectively; the LED luminous module is fixed on the top plate of the heat radiation base and positioned between the two reflecting plates; the light-transmitting cover body is arranged above the top plate of the heat radiation base and is used for covering the LED luminous module; and the at least one voltage transformation element is arranged in the accommodating space of the heat radiation base and electrically connected with the LED luminous module. Therefore, the heat radiation base forms the accommodating space, thereby being capable of increasing the heat radiation area; and furthermore, the LED luminous module can reflect light through the reflecting plates, thereby being capable of improving the lighting brightness.

Description

Can improve the LED fluorescent tube of brightness of illumination

Technical field

The present invention is a kind of LED fluorescent tube that improves brightness of illumination, but is meant a kind of reflection ray especially, to improve brightness of illumination.

Background technology

Lighting apparatus is a daily necessities indispensable in the daily life, changed people's life style, now in general family or the public's indoor scenarios, all can see and use lighting apparatus miscellaneous, for example: fluorescent lamp, illuminating lamp, desk lamp, pendent lamp, neon light or the like, can be improved by lighting apparatus for the dim inconvenience that brings.

For different lighting apparatus, the purposes of its application also has difference, for example: general fluorescent lamp, illuminating lamp, desk lamp ... Deng, it is for the use of general illumination, and the lighting apparatus that some specific uses are also arranged for example: night-light, be and be applied to the illumination that people are provided when sleeping, its luminous power is lower, only is auxiliary usefulness.

The fluorescent tube of traditional type or bulb have quick heating and the high shortcoming of power consumption, and light fixture can cause the problem of environmental protection after discarded, therefore, just develop in recent years and that (Light EmittingDiode is LED) as the technology of light emitting source with light emitting diode.

LED illumination slowly by use that the mankind accept, as a lighting, and use in order to allow the LED lighting show more function, increasing its practicality, real important topic of making great efforts for industry.

Summary of the invention

Main purpose of the present invention is to provide a kind of LED fluorescent tube that improves brightness of illumination, and it has the effect of reflection ray, to reach the raising brightness of illumination.

Another object of the present invention is to provide a kind of LED fluorescent tube that improves brightness of illumination, and it has the effect that increases area of dissipation, improves its radiating effect to reach.

In order to achieve the above object, the present invention is characterized in to include a cooling base, it has a top board and is positioned at the camber plate of top board below, and is formed with an accommodation space, and these top board both sides are formed with the reflector of inclination respectively; One LED light emitting module, it is to be fixed on the top board of this cooling base, is positioned between this two reflector; One printing opacity lid, it is the top board top that is arranged at this cooling base, in order to this LED light emitting module is covered with; And at least one transformation element, it is to be arranged in the accommodation space of cooling base, and electrically connects with this LED light emitting module.

In this way, this radiating seat body forms an accommodation space, can increase its area of dissipation, and this LED light emitting module can pass through this reflector reflection ray, can improve brightness of illumination.

Description of drawings

Below describe conjunction with figs. and embodiment in detail embodiments of the present invention, thus to the present invention how the application technology means implementation procedure that solves technical problem and reach the technology effect can fully understand and implement according to this, wherein:

Fig. 1 is an exploded view of the present invention.

Fig. 2 is the assembled sectional view of Fig. 1.

The specific embodiment

See also Fig. 1 and Fig. 2, for the present invention can improve the LED fluorescent tube of brightness of illumination, it includes a cooling base 10, a LED light emitting module 12, a printing opacity lid 14, a transformation element 16, two electrical components 18 and two side covers 20.Wherein

Cooling base 10 is semi-circular body, the camber plate 24 that it has a top board 22 and is positioned at top board 22 belows, and be formed with an accommodation space 26, and top board 22 both sides are formed with the reflector 28 of tilted configuration respectively, and being formed with guide groove 30 respectively in two reflectors, 28 outsides, the outer surface of camber plate 24 has a plurality of fin 32.

LED light emitting module 12 is provided with a printed circuit board (PCB) 34 and is arranged at a plurality of LED 36 on the printed circuit board (PCB) 34, and it is to be fixed on the top board 22 of cooling base 10 for a printed circuit board (PCB) 34, and between two reflectors 28.

Printing opacity lid 14 its both sides are formed with guide rail 38 respectively, and it is to slip in the guide groove 30 of cooling base 10, and light-passing board 14 is arranged at top board 22 tops of cooling base 10, in order to this LED light emitting module 12 is covered with.Make the light of LED light emitting module 12 can pass through 14 transmissions of printing opacity lid, a part of light is then via after reflector 28 reflections, again via 14 transmissions of printing opacity lid.

Transformation element 16 is to be arranged in the accommodation space 26 of cooling base 10, and electrically connects with LED light emitting module 12.In this way, can reduce the accommodation space of transformation element 16.

Two electrical components 18 are to be arranged at LED light emitting module 12 two ends respectively, and each electrical components 18 is provided with a circuit board 40 and electrical plug 42, and 40 of circuit boards are to form with electrical plug 42 and LED light emitting module 12 respectively to electrically connect.And

Two side covers 20 are to be covered on cooling base 10 two ends, and in order to accommodation chamber 26 is covered, and electrically plug 42 is to wear into side cover 20, and is electrically connected with circuit board 40, and is electrically connected to LED light emitting module 12 via transformation element 16.

In this way, with transformation element 16 hiding being arranged in the accommodation space 26 of cooling base 10, can reduce the accommodation space of light fixture, and heat radiation by cooling base 10, can improve the service life of light fixture, and LED light emitting module 12 can be by reflector 28 reflection sources, to improve the brightness of illumination of light fixture.

Though the present invention discloses as above with aforesaid embodiment; right its is not in order to limit the present invention; anyly have the knack of alike skill person; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, therefore scope of patent protection of the present invention must be looked being as the criterion that the appended claim scope of this specification defined.
