Detailed description of the invention
Detailed description of the invention of the present utility model is, as shown in the figure:
Embodiment 1, a kind of light fixture of uniform-illumination, comprises, lamp socket 1 and light-guiding pillar 2, wherein: this lamp socket 1 comprises connector 11, radiating piece 12 and light emitting diode 13.Radiating piece 12 is one-body molded and surrounding is extended with multiple radiating fin, and radiating piece 12 is arranged on connector 11, and light emitting diode 13 is arranged on radiating piece 12, and the heat energy that light emitting diode 13 luminescence is produced is directly conducted to radiating piece 12 and dispels the heat.
This light-guiding pillar 2 upper and lower surface has reflecting layer 21 and light source incidence face 22 respectively, and reflecting layer 21 can utilize the mode of gold-plated mirror effect to be formed; Light-guiding pillar 2 can be the cylinder etc. of cylinder, polygon cylinder, the cylinder of petal kenel, the cylinder of spiral camber or irregular form; Between the reflecting layer 21 of light-guiding pillar 2 and light source incidence face 22, adjacently situated surfaces has projection surface 23, projection surface 23 place is arranged with multiple plane of refraction 24, plane of refraction 24 can be arc surfaced, as diamond cutting planar or Irregular Boundary Surface shape etc., make plane of refraction 24 can reach the object producing refraction action and diffusion for light, the arrangement in point-like of multiple plane of refraction 24, makes around light-guiding pillar 2 surperficial in out-of-flatness.Light-guiding pillar 2 is directly connected on the radiating piece 12 of lamp socket 1 with the assembling of light-guiding pillar 2 by lamp socket 1, makes the light source incidence face 22 of light-guiding pillar 2 just to the light emitting diode 13 of lamp socket 1.
To sum up above-mentioned, when the utility model is in using state, the light that light emitting diode 13 sends directly can be projected to reflecting layer 21 by the light source incidence face 22 of light-guiding pillar 2, projection surface 23 and plane of refraction 24 is reflexed to again by reflecting layer 21, part light directly can be projected to the external world by projection surface 23, another part light can be incident upon on multiple plane of refraction 24 and produce refraction and diffusion, spread by light-guiding pillar 2 surrounding equably again and be projected to the external world, therefore light fixture 10 significantly can promote illuminance uniformity and the brightness of light-guiding pillar 2 lateral face light source, the luminous situation that light fixture 10 is presented is very attractive in appearance.
Refer to shown in Fig. 4, represent in figure that the light-guiding pillar 2 of light fixture 10 is positioned at light source incidence face 22 place and can be arranged with just to the plane of refraction 221 of light emitting diode 13 further, the light that light emitting diode 13 is sent first is projected to plane of refraction 221 and carries out unirefringence, be projected to reflecting layer 21 back reflection again and carry out birefringence to plane of refraction 24, to reach better diffusion effect, light fixture 10 lateral face light illumination uniformity and brightness is made to understand better.
