[embodiment]
Fig. 2 is the schematic diagram according to a kind of leaded light bar of the embodiment of the utility model.Please refer to Fig. 2, leaded light bar 300 mainly comprises a light entrance face 310 and a light-emitting face 320, and wherein the material of leaded light bar 300 for example is polymethyl methacrylate, poly-sour fat, cycloolefin macromolecule or other transparent material.Light entrance face 310 has Shu depressed part 312, wherein has a ripple 312a on the wall of depressed part 312.Light-emitting face 320 is positioned at the opposite of light entrance face 310.
From the above, the depressed part 312 of leaded light bar 300 is suitable for being adjacent to a light source 400 configurations, and wherein light source 400 for example is light-emitting diode, fluorescent tube or white heat bulb or the like.When the light L that is sent when light source 400 enters leaded light bar 300 via the depressed part on the light entrance face 310 312, owing to have ripple 312a on the wall of depressed part 312, it can increase the anaclasis area of depressed part 312 corresponding to light L effectively, therefore as light L during from light-emitting face 320 outgoing, leaded light bar 300 can increase the width of the bright band B on the light-emitting face 320 effectively.Be with, the brightness of light-emitting face 320 can existing leaded light bar the brightness of light-emitting face more even.
In the disclosed embodiment of the utility model, the ripple 312a of depressed part 312 for example is the zigzag ripple.When ripple 312a is the zigzag ripple,, is light L is dispersed more equably, and then makes that the brightness of light-emitting face 320 is more even with such design because the sawtooth ripple can increase the anaclasis area of depressed part 312 corresponding to light L effectively.It should be noted that present embodiment is not that in other embodiment of the utility model, shape more can be the trapezoidal ripple or the ripple of other shape outside the ripple 312a in order to qualification the utility model except the zigzag ripple.
When ripple 312a was the zigzag ripple, present embodiment more can form an arc lead angle P respectively at the top of ripple 312a.Thus, when light L shone the top of ripple 312a, present embodiment just can make the more even of light L diffusion via arc lead angle P.In addition, present embodiment can also be respectively forms an arc lead angle Q in the bottom of ripple 312a, so that light L is when shining the bottom of ripple 312a, it is more even that light L can spread.Certainly present embodiment more can form arc lead angle P and arc lead angle Q at the top and bottom of ripple 312a the while, so that light L can have better diffusion effect.
From the above, in the present embodiment, except adopting the zigzag ripple, depressed part 312 more can be the V-arrangement depressed part, and wherein depressed part 312 has two adjacent walls.Preferably, the angle theta between two walls for example is between 80 ° to 110 °.Thus, depressed part 312 just can increase corresponding to the anaclasis area of light L.It should be noted that, present embodiment is not the profile in order to the depressed part 312 that limits the utility model, in other embodiment of the utility model, depressed part 312 except being the V-arrangement depressed part, more can be circular depression, trapezoidal recess portion or the depressed part of other geometry.
More preferably, present embodiment more can be in leaded light bar 300 doping light diffusing agent 330.Thus, via the effect of light diffusing agent 330, light L just can spread in leaded light bar 330 more equably, and then makes that the brightness on the light-emitting face 320 can be more even.
In addition, the utility model more can be embedded in the leaded light bar in one shell body and form a housing face-plate.Please refer to Fig. 3, it is the schematic diagram according to a kind of housing face-plate of the embodiment of the utility model.Housing face-plate 600 mainly comprises a shell body 500 and at least one leaded light bar 300.Shell body has one first 510, and first 510 has at least one strip hole 512.Leaded light bar 300 is embedded in respectively in the corresponding strip hole 512.In addition, the housing face-plate 600 of the utility model more can have at least one light source 400 (please refer to Fig. 2), and it is positioned at the depressed part 312 of the leaded light bar 300 of correspondence.Thus, because leaded light bar 300 can have more existing leaded light bar and have more uniform brightness when being subjected to the irradiation of light L, therefore when light source 400 was opened, housing face-plate 600 just can have than beautiful visual effects.
In sum, the utility model mainly is to form a ripple on the wall of the depressed part of leaded light bar.Be with, when a light when depressed part is incident to the leaded light bar, the utility model just can increase the anaclasis area of depressed part corresponding to the light of incident through ripple thus.Because depressed part increases corresponding to the ray refraction area of incident, therefore light just can spread in the leaded light bar equably, be with when light during, can have wideer bright band and demonstrate brightness uniformly than prior art on the light-emitting face in the light-emitting face outgoing.
In addition, the utility model more can make the anaclasis area corresponding to the light of incident of depressed part increase via the zigzag ripple, and then make light when the light-emitting face outgoing, can have wideer bright band and demonstrate brightness uniformly than prior art on the light-emitting face.In addition, when the ripple on the wall of depressed part is the zigzag ripple, the utility model more can form the arc lead angle in top, bottom or the while of ripple on both, so that the light of incident can have more uniform diffusion effect when penetrating these lead angles.
Moreover, the depressed part of the utility model more can be the V-arrangement depressed part, the utility model just can be via the geometric shape of V-arrangement depressed part thus, increase the anaclasis area of depressed part corresponding to the light of incident, and then make light when the light-emitting face outgoing, can have wideer bright band and demonstrate brightness uniformly than prior art on the light-emitting face.
In addition, the utility model light diffusing agent that more can mix in the leaded light bar is so that light can spread in the leaded light bar more equably.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; when can doing a little change and retouching, so the protection range of the utility model attached claim person of defining after looking is as the criterion.
