The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As shown in Figures 1 and 2, the utility model light emitting diode (Light Emitting Diode, LED) light fixture 100 comprises main body section bar 10, LGP 20, luminescence unit 30 and end cap 40.

Described main body section bar 10 is used for carrying luminescence unit 30 and LGP 20, and in the present embodiment, described main body section bar 10 is aluminium section bar, and is one-body molded by aluminium extruded, and enough support strength and heat-sinking capabilities can be provided, and its moulding is simple in addition, product weight is lighter.Be appreciated that ground, described main body section bar 10 is not limited to aluminium section bar shown in the present embodiment.

Described main body section bar 10 comprises the side plate 14 of the base plate 12 that is the lengthwise shape and the both sides that are formed at respectively base plate 12.The edge of biside plate 14 is bent to form flanging 140 towards base plate 12 respectively, the both sides of base plate 12 extend to form respectively fin 120 corresponding to described flanging 140, form the draw-in groove 16 of a lengthwise between each fin 120 and the corresponding flanging 140, be used for fixing described LGP 20.In addition, wherein side plate 14 interior formation accommodation spaces 18 are used for installing described luminescence unit 30.Described accommodation space 18 is positioned at the outside of draw-in groove 16 and is connected with draw-in groove 16.Be appreciated that ground, also can all form accommodation space 18 in that biside plate 14 is interior, thereby place respectively luminescence unit 30.

Described luminescence unit 30 comprises base 32 in the accommodation space 18 of the side plate 14 that is inserted in main body section bar 10, be fixed in the circuit board 34 in the base 32 and be fixed in light source 36 on the circuit board 34.In the present embodiment, described light source 36 is LED, and evenly the compartment of terrain is arranged on the circuit board 34, and its light-emitting area is towards described base plate 12 and perpendicular with base plate 12.On the described circuit board 34 control circuit can be set, thereby control the light effect that of described LED light fixture 100.For making things convenient for being connected between light source 36 and the extraneous power supply, by outside extracting power supply cord 50 on the described circuit board 34, be equipped with cableties 60 on the described power line 50, Positioning Power line 50 when assembling, thus avoid mutually twining between the power line 50.The outer end of power line 50 is provided with water joint 70, avoids airborne steam to enter the inside of LED light fixture 100, the service life of impact electrical connection and light source 36.

Described LGP 20 is transparent thin board, and its material is generally acrylic.Described LGP 20 comprises towards the exiting surface 22 in the external world and by vertically extending two long and narrow sides 24, described exiting surface 22 both sides, when the both sides of LGP 20 respectively geometrical clamp be located in the draw-in groove 16 of main body section bar 10 both sides, described side 24 is positioned at the side plate 14 of main body section bar 10, and over against the exiting surface of described light source 36.When described light fixture 100 work, the light that described light source 36 externally excites under the driving of power supply, side 24 by LGP 20 enters in the LGP 20, and in LGP 20 via being penetrated to extraneous by the exiting surface 22 of LGP 20 after Multi reflection, the scattering, because the scattering process of LGP 20, finally even by the light of LGP 20 exiting surfaces 22 ejaculations, form area source, promote decorative lighting effect.

In addition, even described LED light fixture 100 is in non-working condition by day, because described luminescence unit 30 is the outsides that are contained in the side plate 14 of main body section bar 10 and are positioned at LGP 20, thereby described luminescence unit 30 is to be in invisible mode, play stealthy effect, the overall appearance color of described LED light fixture 100 is decided by described main body section bar 10, thereby its overall appearance is not subjected to the impact of described light source 36, can be consistent with skin.

Described end cap 40 is located at the two ends of main body section bar 10 and LGP 20, its shape, structure are corresponding with main body section bar 10, thereby main body section bar 10, LGP 20 and end cap 40 common formation one closed structures avoid extraneous steam and dust to enter the service life of the LED light fixture 100 interior LED of impact light fixtures 100.In the present embodiment, on main body section bar 10, certain described end cap 40 also can pass through alternate manner with main body section bar 10 to described end cap 40, connects such as modes such as welding, riveted joints, is not limited to the screw lock shown in the present embodiment and connects by screw 90 screw locks.

In addition, the back side at the base plate 12 of the main body section bar 10 of described LED light fixture 100, namely a side of described LGP 20 is connected with two mount pads 80 dorsad, be used for described LED light fixture 100 is installed in building, in the present embodiment, described mount pad 80 is fixed on the side plate 14 of described main body section bar 10 by screw 90.
