[specific embodiment]
Please refer to shown in Fig. 1 to Fig. 3, a kind of light fixture 1, comprises radiator 10, is installed on LED light source 21 and the reflector 30 of radiator 10.Reflector 30 is one-body molded with radiator 10.Light fixture 1 comprises exiting surface 40 down, and the part light of LED light source 21 is from exiting surface 40 outgoing after reflector 30 reflections, and the light-emitting area of LED light source 21 is towards the side of light fixture 1.The reflector 30 of light fixture 1 is positioned at the top of light fixture 1, and exiting surface 40 is positioned at the below of light fixture 1, and LED light source 21 is positioned at the side of light fixture 1, and the light-emitting area of LED light source 21 is also towards the side of light fixture 1.The lower surface that the exiting surface 40 of take is light fixture 1, light fixture 1 has the side vertical with lower surface (not label).LED light source 21 towards side can be the positive side of light fixture 1, can be also side top, side-lower etc.In the present embodiment, LED light source 21 towards be side top, in other embodiment, can adjust as required the angle of LED light source 21.Reflector 30 of the present utility model and radiator 10 are one-body molded, and light source board 20 is installed on radiator 10, makes reflector 30 for reflection ray, can be used in again heat radiation.And integrated structure makes the utility model light fixture 1 simple in structure, very convenient manufacture and assembling.
Exiting surface 40 is a virtual face, and the exiting surface 40 in the utility model is virtual of forming between the end of reflector 30 and radiator 10 free ends.Between light source board 20 and exiting surface 40, shape has angle.The exiting surface 40 of light fixture 1, light source board 20 and reflector 30 form an optics cavity 70.In the present embodiment, in optics cavity 70, the angle between light source board 20 place planes and exiting surface 40 is obtuse angle.In other embodiment, the angle between light source board 20 place planes and exiting surface 40 can be also right angle or acute angle.When the angle between light source board 20 place planes and exiting surface 40 is obtuse angle, the light source of light source board 20, towards reflector 30, makes light source can, directly towards exiting surface, better not prevent the generation of light source granular sensation like this.The structure of the utility model light fixture 1 makes light fixture 1 can either realize the granular sensation that side is luminous, prevent light fixture 1 exiting surface, does not need to use again LGP.Thereby make side luminous light fixture 1 simple in structure, convenient manufacture and assembling.
Concrete, reflector 30 comprises installs the flat part 31 of reflector 50 and the curved portions 32 being connected with flat part 31.The end 320 of curved portions 32 is roughly positioned at same plane with free end 101 tops of radiator 10.The plane forming between free end 101 tops of the end 320 of curved portions 32 and radiator 10 is exiting surface 40.Curved portions 32 is reflecting surface 322 towards the one side of light source board 20, and the reflecting surface 322 of curved portions 32 is diffuse surface.In the present embodiment, the reflecting surface 322 of curved portions 32 is coated with diffuse reflection powder.In other embodiment, diffuse surface also can be made by additive method.Reflector 30 also comprises installation portion 33.Installation portion 33 for outer mounting structure (not shown) thus be connected light fixture 1 be fixed on to outer mounting structure.
In the present embodiment, light fixture 1 is the light fixture of desk lamp 9.Desk lamp 9 also comprises shell 90, face shield 91 and bracing frame 92.Light fixture 1 is installed in the shell 90 of desk lamp 9.Shell 90 comprises upper cover 901 and lower cover 902, and face shield 91 is installed on lower cover 901.Light fixture 1 is fixed on lower cover 902 by screw, and the lower cover 902 that is assembled with light fixture 1 is fixed on upper cover 901 by screw.Between upper cover 901 and lower cover 902, form receiving space, light fixture 1 is arranged in receiving space.The light source 21 of light fixture 1 is positioned at the side of receiving space.The reflector 30 of light fixture 1, in receiving space, with respect to fastener 60, is positioned at the position of more close upper cover 901.The fastener 60 of light fixture 1, in receiving space, with respect to reflector 30, is positioned at the position of more close lower cover 902.In other embodiment, light fixture 1 also can be for the light fixture of other types, such as wall lamp, floor lamp etc.
