The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

See also Fig. 1～3, be respectively first of the utility model preferred embodiment and implement the top exploded view of aspect, look up exploded view and schematic appearance.As shown in the figure, this LED light fixture 1 is applicable to amusement park, gymnasium, exhibition center, household room and distinguishes the indoor and outdoor in the places such as public chamber, and it comprises an electrical connector 10, a Coupling 11, a lamp socket 12, a circuit substrate 13, three light emitting diodes 14, a lens mount 15, a lens cap 16 and light covers 17.This electrical connector 10 is electrically connected an external power source (not shown) so that this LED light fixture 1 work energy to be provided.These lamp socket 12 tops are provided with a groove 120, and this lamp socket 12 is made by the high purity aluminum alloy material, and by a plurality of the first fins of the outside radiation formation in center, these first fins from top to bottom bending are brought together and are made these lamp socket 12 outward appearances be cup-like structure wide at the top and narrow at the bottom, have when reaching the effect of better thermal diffusivity attractive in appearance outside shape.The slightly cylindrical structure of this Coupling 11, relative both sides, its top convex with respectively a clamping part 110 to be socketed this lamp socket 12, establish this electrical connector 10 and be provided with a plurality of screw threads 111 bottom it with lock, but make this this electrical connector 10 of lamp socket 12 rapid-assemblings.

And, this circuit substrate 13 places in this groove 120, seeing through wire and a circuit converter (not shown) is electrically connected this electrical connector 10 and couples these light emitting diodes 14, drive these light emitting diodes 14 to obtain work energy luminous, and this circuit converter can be provided with luminous efficiency and the service life of constant-current drive circuit to improve this LED light fixture 1.This lens cap 15 can see through a plurality of screws 150 and be locked on this circuit substrate 13, is provided with carrying and makes this lens cap 16 cover these light emitting diodes 14.This lens cap 16 is by being one of triangular chair structure support 160 and at least one lens body 161 is formed, the top of this lens body 161 connects surface under this support 160, and its bottom indent is formed with a slotted eye, be provided with this light emitting diode 14 of accommodating correspondence, hence one can see that, the position of these lens body 161 corresponding these light emitting diodes 14 and arranging.This light cover 17 can be made of a transparent spherical cap 170 and a retainer ring 171, seals this lens cap 16, these light emitting diodes 14 and this circuit substrate 13 in this groove 120 in order to connect this lamp socket 12.Incidentally be that this circuit substrate 13 can be aluminium base, and this retainer ring 171 is made and be formed with a plurality of the second fins by aluminum alloy material or plastic material, makes further improving heat radiation efficiency.

In this enforcement aspect, the footpath of this light cover 17 is wide to be 70mm, and this electrical connector 10 can be according to the practical market demand and select Different Rule, and making this LED light fixture 1 is that 88～95mm is high.These light emitting diodes 14 are take one of this LED light fixture 1 central shaft as benchmark equidistantly around setting, and this support 160 and this lens body 161 can be one-body molded and can be made by PMMA material or optical grade PC material, the top surface system of this support 160 is through the cloudy surface processing or be honeycomb type structure, to promote the illumination uniformity.So, the former optical path trend that this lens cap 16 of mat improves these light emitting diodes 14 can form better smooth shape layout, and applicable in each place, field.
