The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:

Characteristic in above-mentioned purpose of the present invention and structure thereof and function, will be explained according to appended graphic preferred embodiment.

Fig. 1 is perspective exploded view of the present invention; Fig. 2 is that the present invention analyses and observe decomposing schematic representation; Fig. 3 is the three-dimensional combination of the present invention schematic diagram; Fig. 4 is that the present invention analyses and observe combination schematic diagram; Fig. 5 is the local enlarged diagram of Fig. 4.LED light fixture comprises that a shell 10 holds a control element 20, a fan 21, a radiator 22, a LED module 23 and a vibrator 24 as shown in Figures 1 to 5, and wherein this fan 21 and LED light emitting module 23 are separately positioned on the relative both sides of radiator 22.This vibrator 24 is arranged on the side that 22 pairs, this radiator should fan 21, and between this radiator 22 and this fan 21, this vibrator 24 is expressed as miniature flat dither motor in this enforcement, and it can be applicable to vibrative running in small space.This control element 20 includes circuit board 201 and electronic component 202 and electrical pin 203, must obtain electric energy from the outside of LED light fixture, then offers LED module 23 and fan 21 power supply required with vibrator 24 runnings.

This shell 10 comprises that a lamp socket 11 and lampshade 12, one serpentine channel 13 rings are located at this lamp socket 11 with around these lampshade 12 opposite positions.Lamp socket 11 has a bottom 111 and extends upward and define a spatial accommodation 112, and one end that extend upward this bottom 111 forms a non-rectilinear ora terminalis 113, this non-rectilinear ora terminalis 113 defines an opening 114 and is communicated with this spatial accommodation 112, and the inner side of this spatial accommodation 112 is provided with a plurality of connecting portions 115.

This lampshade 12 has a front end and a rear end, this front end is provided with a loophole 121, one lens 25 are arranged on loophole 121 places, this rear end is provided with a plurality of connecting portions 115 of a plurality of receiving portion 122 these lamp sockets 11 of docking, the outside of this lampshade 12 has 125 pairs of a radial lugs 124 and lower end side should non-rectilinear ora terminalis 113, this radial lugs 124 has outside and the free end 1242 that root 1241 one connect this lampshade 12 and protrudes out towards this non-rectilinear ora terminalis 113, this lower end side 125 is positioned at root 1241 belows of this radial lugs 124, lampshade 12 inner sides are provided with a plurality of Fixed Divisions 127, by affixed element for example screw (without graphic) and these Fixed Division 127 interlockings, make this radiator 22 and fan 21 connect this lampshade 12, and and then the order LED module 23 that is positioned at radiator 22 1 sides correspond to the lens 25 of loophole 121.

After these lampshade 12 these lamp sockets 11 of docking, between non-rectilinear ora terminalis 113 and this radial lugs 124 and lower end side 125, define this serpentine channel 13, this non-rectilinear ora terminalis 113 comprises a radial flange 1131 and an axial bead 1132, this radial flange 1131 is toward radial projection, then towards axially protruding out, to form this axial bead 1132 from upwardly extending one end, bottom 111 of this lamp socket 11, so radial flange 1131 and this axial bead 1132 formation settings of 90 degree in fact.

This serpentine channel 13 is for the passage of several bendings and have the inside that a first end 134 is communicated with the outside of shell 10 and one second end 135 connection shells 10, this serpentine channel 13 specifically comprises that a first passage 131 is between the free end 1242 of this radial lugs 124 and this axial bead 1132, this first passage 131 is communicated with a second channel 132 from vertical extension of this first end 134, these second channel 132 horizontal-extendings are communicated with a third channel 133, and this third channel 133 is to extend vertically up to the spatial accommodation 112 that this second end 135 is communicated with this lamp socket 11.

Especially be noted that, because vibrator 24 can reach the even hyperacoustic frequency of infrasound, the feature that amplitude is less, therefore utilize the dither of vibrator 24, during running, can shake off to be attached to ash (powder) dirt or foreign matter on fan 21 and radiator 22, then the fan 21 by running is blown out to the external world from shell 10 is interior through serpentine channel 13 by the dust of shaking off.Moreover vibrator 24 has that height shakes frequently, short arc and low noise, so the noise of system stack is very low, and the vibration of generation can not affect the normal operation of light fixture itself.In addition, see through control element 20 and control running startup and the dwell time of vibrator 24, for example set vibrator 24 running in every 8 hours 15～20 seconds, because the time of vibration of vibrator 24 is controlled therefore vibrator 24, on the impact of whole light fixture, can be controlled in minimum zone.

In addition by ring, be located at this lamp socket 11 and be communicated with the inner space of external environment and the shell 10 of shell 10 with these lampshade 12 opposite positions serpentine channel 13 around, the passage of usining as gas flow, because serpentine channel 13 is that vertically disposed first passage 131 is communicated with horizontally disposed second channel 132, second channel 132 is being communicated with vertically disposed third channel 133, between first passage 131 and second channel 132, form first bending region, between second channel 132 and third channel 133, form the second bending region, by such setting, prevent that foreign matter from entering in shell 10.

In sum, the present invention holds a vibrator 24 between radiator 22 and fan 21 in LED light fixture, action by vibrator 24 vibrations shakes off to be attached to dust or the foreign matter on fan 21 and radiator 22, to make dust blow out LED light fixture via fan running, and be provided with serpentine channel 13 ring and be located at light fixture around, one end of this serpentine channel 13 is communicated with the external environment of LED light fixture, and the non-directional extension of the other end is communicated with in LED light fixture, prevents that foreign matter from entering in LED light fixture.

Although the present invention discloses as above with embodiment; so it is not in order to limit the present invention, any person skilled in the art person, without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, so protection scope of the present invention is worked as with standard that claims are decided to be.
