Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of power fixture structure of LED bulb lamp.
Background technology
Low due to long service life, the energy consumption of LED lamp, energy savings is remarkable, so the LED lamp has been widely used in daily life as light source, as the LED bulb lamp.Yet along with the increase of LED quantity in the LED bulb lamp and the raising of power and brightness, the heat that produces when making the work of LED lamp is unprecedented soaring.Therefore, the radiating effect that how to improve the LED bulb lamp becomes significant problem in LED bulb lamp technology.
In prior art, the LED bulb lamp comprises: aluminium base, be arranged on LED lamp pearl and power module and heat abstractor on aluminium base.When the operating illumination of LED bulb lamp, the heat that LED lamp pearl produces reaches heat abstractor through aluminium base, then is distributed by radiation by heat abstractor.But because power module generally is horizontal positioned, cause radiating effect not good, and the heat loss through radiation area of heat abstractor is limited, affects equally radiating effect, and then affects the life-span of LED bulb lamp.
The utility model content
The utility model provides a kind of LED bulb lamp that dispels the heat good, improves by the radiation aluminium body to the LED bulb lamp, to solve the deficiency of prior art.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of power fixture structure of LED bulb lamp is located in the LED bulb lamp, and this LED bulb lamp comprises lamp holder and the diffuser that is installed on the Lamp cup two ends, described Lamp cup inside is provided with circuit board, described Lamp cup inside is provided with support, and described support extends and accommodates described circuit board along the Lamp cup inwall, and the bottom of described Lamp cup is the design of closing up, closing in place is provided with the clamping ring that is connected with lamp holder, some through holes on described clamping ring; Also be provided with radiation aluminium body and aluminium base in the accommodation space that described Lamp cup and diffuser form, aluminium base is provided with LED lamp pearl; Wherein, also be provided with the PCB(Printed circuit board of a pair of holding circuit board on clamping ring, printed circuit board (PCB)) draw-in groove, circuit board vertically inserts this PCB draw-in groove with fixing.
Described radiation aluminium body comprises a matrix, and this matrix periphery evenly is provided with some radiating fins, forms heat dissipation channel between described some radiating fins, and forms cross-ventilations with some through holes on clamping ring, further strengthens radiating effect.
LED bulb lamp of the present utility model has been strengthened cross-ventilation, thereby has been improved radiating effect by adopting the PCB draw-in groove so that circuit board is vertically placed; In addition, adopt the radiation aluminium body with heat radiation fin structure, greatly increased the surface radiating area, and formed heat dissipation channel between some radiating fins, the through hole on this heat dissipation channel and clamping ring forms convection current, forms the heat dissipation channel that radiating effect is good.
Description of drawings
Fig. 1 is the explosive view of LED bulb lamp in embodiment of the present utility model;
Fig. 2 is the upward view of the Lamp cup of the radiation aluminium body in embodiment of the present utility model.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As a specific embodiment, as depicted in figs. 1 and 2, the power fixture structure of a kind of LED bulb lamp of the present utility model, be located in the LED bulb lamp, this LED bulb lamp comprises lamp holder 1 and the diffuser 6 that is installed on Lamp cup 2 two ends, Lamp cup 2 inside are provided with circuit board 3, and circuit board 3 comprises by dull and stereotyped power panel and the lamp plate that connects of accumulation of heat; The bottom of Lamp cup 2 is the design of closing up, and its inside also is provided with support 21, and support 21 extends and accommodates circuit board 3 along Lamp cup 2 inwalls.The end of lamp holder 1 also has electrode 8.
Closing in place of Lamp cup 2 is provided with the clamping ring 22 that is connected with lamp holder 1, and on clamping ring 22,3 through holes 221 wherein, also are provided with the PCB draw-in groove 222 of a pair of holding circuit board 3 on clamping ring 22, and circuit board 3 vertically inserts in this PCB draw-in groove 222 with fixing.This power fixture structure is simple and easy to make, and has strengthened cross-ventilation, thereby has improved radiating effect.
Also be provided with radiation aluminium body 4 and aluminium base 5 in the accommodation space that Lamp cup 2 and diffuser 6 form, aluminium base 5 is provided with LED lamp pearl, radiation aluminium body 4 comprises matrix 41, being shaped as of this matrix 41 is cylindrical, matrix 41 peripheries evenly are provided with some radiating fins 42, form heat dissipation channel between some radiating fins 42.These some radiating fins 42 realize increasing area of dissipation by increasing surface area, and form cross-ventilations with 3 through holes 221 on clamping ring 22, strengthen radiating effect.Radiation aluminium body 4 and aluminium base 5 are by screw 7 lockings.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
