Abstract

The invention discloses a light emitting diode (LED) lamp device. The device comprises a radiating base, an LED light emitting module, a transparent cover body and at least one voltage transformation element, wherein the radiating base is semicircular, is provided with a top plate and an arc-shaped plate positioned below the top plate and forms an accommodating space; the LED light emitting module is fixed on the top plate of the radiating base; the transparent cover body is arranged above the top plate of the radiating base and is used for covering the LED light emitting module; and the at least one voltage transformation element is arranged in the accommodating space of the radiating base and is electrically connected with the LED light emitting module. The accommodating space is form in the radiating base, so that the radiating area can be increased; and the voltage transformation element is arranged in the accommodating space, so that the configuration space of a lamp can be reduced, and the device is more practical.

Description

The LED lamp device

Technical field

The present invention is a kind of LED lamp device, is meant a kind of LED light fixture especially, can effectively increase its radiating effect.

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 transmission illumination equipment 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 lamp device, and its tool increases the effect of area of dissipation, to reach the raising radiating effect.

Another object of the present invention is to provide a kind of LED lamp device, and it can be arranged at the transformation element in the heat radiation pedestal, to reach the purpose that reduces the light fixture accommodation space.

For reaching above-mentioned effect and purpose, technical characterictic of the present invention is to include a cooling base, and it is semicircle, has a top board and is positioned at the camber plate of top board below, and be formed with an accommodation space; One LED light emitting module, it is fixed on the top board of this cooling base; One printing opacity lid, it is arranged at the top board top of this cooling base, in order to this LED light emitting module is covered with; And at least one transformation element, it is 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 transformation element is arranged in this accommodation space, can reduce the configuration space of light fixture, makes it more practical.

The specific embodiment

Below will cooperate graphic and embodiment describes embodiments of the present invention in detail, by this 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.

See also Fig. 1 and Fig. 2, be LED lamp device of the present invention, it includes a cooling base 10, a LED light emitting module 12, a reflecting plate 14, a printing opacity lid 16, a transformation element 17, two electrical assembly 18 and two side covers 20.Wherein:

Cooling base 10 is semicircle, 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 guide groove 28 respectively, the outer surface of camber plate 24 has a plurality of fin 29.

LED light emitting module 12 is provided with a printed circuit board (PCB) 30 and a plurality of LED32, and it is fixed in printed circuit board (PCB) 30 on the top board 22 of cooling base 10.

Reflecting plate 14 is arranged on the printed circuit board (PCB) 30, and it is formed with a plurality of hollow holes 34 with respect to LED 32 positions, and LED32 can be exposed by hollow hole 34, and reflecting plate 14 both sides respectively shape the light guide sheet 36 of inclination is arranged.

Printing opacity lid 16 its both sides are formed with guide rail 38 respectively, and it slips in the guide groove 28 of cooling base 10, and printing opacity lid 16 is arranged at top board 22 tops of cooling base 10, in order to this LED light emitting module 12 is covered with.

Transformation element 17 is arranged in the accommodation space 26 of cooling base 10, and electrically connects with LED light emitting module 12.

Two electrical assemblies 18 are arranged at LED light emitting module 12 two ends respectively, and each electrical assembly 18 is provided with a circuit board 40 and electrical plug 42.And

Two side covers 20 are covered on cooling base 10 two ends, and in order to accommodation chamber 26 is covered, and electrically plug 42 wears 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 17.

In this way, with transformation element 17 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, reach LED light emitting module 12 and can pass through reflecting plate 14 reflection sources, with the brightness of illumination of hand lamp tool.
