Please refer to Fig. 1 and Fig. 2, the LED light fixture that the utility model embodiment provides comprises radiator 10 and is arranged at the LED light source 20 in described radiator 10; Described radiator 10 comprises housing 11 and is arranged at the radiator structure 12 on described housing 11, and in described housing 11, have the accommodating cavity 110 for placing described LED light source 20, described radiator structure 12 comprises the multiple fin 121 around described LED light source 20; Described LED light fixture also comprises and covers at described LED light source 20 tops and be fixedly installed in the lens 30 of described accommodating cavity 110 bottoms and be fixedly installed on described lens 30 and be placed in the reflector 40 in described accommodating cavity 110, and described LED light source 20, described lens 30 are located along the same line with the axis of described reflector 40; Described LED light source 20 comprises the substrate 21 and the multiple LED lamp pearl 22 being arranged on described substrate 21 that are fixedly installed in described accommodating cavity 110 bottoms; Described lens 30 comprise the holder 31 that is oppositely arranged with described substrate 21 and arch upward and cover at the lampshade 33 of described LED lamp pearl 22 exiting surface one sides along described holder 31, described holder 31 is provided with described substrate 21 and fixes the stopper slot 310 connecting and be positioned at the screwed hole 312 of described lampshade 33 relative both sides, and screw 50 is through described screwed hole 312 and be fixedly installed in described accommodating cavity 110 bottoms; Described reflector 40 comprise the cup 41 being oppositely arranged with the chamber wall of described accommodating cavity 110 and there is installing port 420 and with described cup 41 one-body molded and make cup the end 42, described lampshade 33 is arranged in described reflector 40 along described installing port 420.
The LED light fixture that the utility model embodiment provides by arranging stopper slot 310 and screwed hole 312 on described lens 30, and utilize screw 50 through screwed hole 312, described lens 30 to be directly fixed on substrate 21, utilize stopper slot 310 to coordinate with substrate 21 so that described lens 30 are spacing and compress described substrate 21, make assembling simpler, and ensured the matching degree of lens 30 with LED light source 20 exiting surfaces, make hot spot better effects if, angle more accurate.
In this embodiment, described holder 31 is with described lampshade 33 by glueing joint shape glue part in aggregates, and this can be avoided making an annulus for empty avoiding exiting surface is set, and makes reserved outlet position and 50, screw on annulus limit and cause glue-joint strength poor; And easily distortion and cause jack-up lens 30 or reflector 40 after preventing from being heated, affect light effect, also can cause that described substrate 21 is not tight with described radiator 10 combinations, impact heat radiation because being out of shape rear discontinuity, reduce described 20 life-spans of LED light source, affect product quality.Empty avoiding exiting surface refers to that middle bright dipping part needs hollow out to avoid exiting surface herein.
The LED light fixture that the utility model embodiment provides is by directly fixing described LED light source 20 spacing described LED light source 20 of described lens 30, particularly, according to described substrate 21 sizes, corresponding step-like stopper slot 310 is set on described lens 30, limiting described LED light source 20 by stopper slot 310 can not move along in-plane, simultaneously by screw 50 by described lens 30 with on radiator 10.Preferably, described lens 30 are made up of heat-resisting high light transmissive material, in LED lamp pearl 22 temperature rise temperature ranges, can not cause distortion, described lens 30 can, because the variation of temperature rise changes, can not ensure out the same designing requirement of light effect all the time with described LED light source 20 exiting surfaces.
The heat that the utility model embodiment utilizes radiator 10 that LED light source 20 is produced in luminescence process conducts in extraneous air, the heat accumulation that LED light source 20 produces is in the accommodating cavity 110 of described housing 11, air in accommodating cavity 110 is subject to the impact of heat, temperature raises, density gaps 16, hot-air in accommodating cavity 110 is derived by fin 121, thereby reduced the interior air themperature of accommodating cavity 110, the radiating rate of radiator 10 is fast, effective.
Please refer to Fig. 1 and Fig. 2, further, described fin 121 extends and arranges separately along described housing 11 short transverses, described in adjacent two, between fin 121 and the upper end of described housing 11 sidewalls, forms air outlet slit 13.Understandably, described short transverse is vertical direction, refers to that when described radiator 10 is vertically placed, LED light source 20 down quadrature is penetrated.Utilize multiple fin 121 that described accommodating cavity 110 is divided into multiple little cavitys, each little cavity is arranged around described LED light source 20 bottoms, and each loculus body is to there being an air outlet slit 13, and such structure convection effects is more obvious, has further promoted the radiating effect of radiator 10.
Please refer to Fig. 1 and Fig. 2, further, described radiator 10 also comprises the stiff end 14 being fixedly connected with described reflector 40, and described housing 11 is provided with breach 15 in the side near stiff end 14, and described breach 15 is arranged along described housing 11 sidewall spacers.Understandably, utilize retainer ring that described radiator 10 is fixedly connected with described reflector 40, preferably, utilize thread connecting mode to realize fixed installation.By multiple breach 15 are set on radiator 10, so that outside air enters in described accommodating cavity 110 through described breach 15, and the air of each direction can flow in accommodating cavity 110 along the breach of respective direction 15, radiating effect is more balanced, to carry out cooling to described LED light source 20.
Please refer to Fig. 1 and Fig. 2, further, between the cup 41 of described reflector 40 and the chamber wall of described accommodating cavity 110, have the gap 16 communicating with described breach 15, described gap 16 and described breach 15 form the air intake 17 of described radiator 10.Understandably, hot-air in described accommodating cavity 110 can flow out outside described accommodating cavity 110 by air outlet slit 13, outside air enters in accommodating cavity 110 so that the air in described accommodating cavity 110 forms convection current by air intake 17, take away heat in accommodating cavity 110 and because the temperature of outside air is low with respect to the air themperature in accommodating cavity 110, thereby reduced the temperature in accommodating cavity 110.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
