Embodiment
Embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings.
A kind of specular removal panel light, including:Light guide plate 1 and lamp bar 2, the lamp bar 2 is provided with multiple LED lamp beads 3, described The both ends of light guide plate 1 are arranged with the lamp bar 2, and the upper and lower surface of the light guide plate 1 is covered with reflective sheeting 4, the light guide plate 1 Side is additionally provided with diffuser plate 5;
The LED lamp bead 3 is 4014 lamp beads, and its lighting angle is 115 °~125 °, when the light guide plate 1 is 2T light guide plates When 1, the distance between the surface of the LED lamp bead 3 and the light guide plate 1≤0.17mm;When the light guide plate 1 is 3T light guide plates When 1, the distance between the surface of the LED lamp bead 3 and the light guide plate 1≤0.46mm.By control the size of LED lamp bead 3 with And lamp bead surface and the spacing of light guide plate 1, improve light efficiency.
As seen in figure la and lb, panel lamp source sets about allowing more using 4014 narrower lamp beads of light-emitting area from light source LED light source is more nearly line source, while shortens its light diffusion length, so as to allow more light to enter in light guide plate 1.Tradition LED lighting angles be 120 ° or so, the surface of LED lamp bead 3 and light guide plate 1 can be limited according to the thickness of light guide plate 1 and LED width Distance, but simultaneously because each component machining accuracy problem of panel light, causes the distance to be difficult to again, therefore this measure Purpose is the size for reducing light source, so as to reduce the diffusion area of light extraction.
From panel light structure design on, for panel light coupling efficiency it is low the problem of, we progressively upgrade improve lamp bar 2 The luminous ratio for being coupled into light guide plate 1,4014 lamp beads collocation 2T light guide plates 1 are directed to, by calculating, it is necessary to which LED surface arrives The distance controlling of light guide plate 1 then needs control within 0.46mm within 0.17mm using 3T, this each group for panel light Part makes precision and proposes very big challenge.Traditional reflective sheeting 4 and the area of light guide plate 1 have light and spilt and consistent, only reflect The light passed through from the back of light guide plate 1, but in the place that lamp bar 2 is combined with light guide plate 1, it is introduced into light guide plate 1.
The width of the reflective sheeting 4 is more than the width of the light guide plate 1, and its length is more than the length of the light guide plate 1;Institute LED lamp bead 3 is stated to be sealed among the reflective sheeting up and down 4 of the light guide plate 1.
Can be by the dimension enlargement of reflective sheeting 4 so that reflective sheeting 4 stretches out from the edge of light guide plate 1, and the light that LED is sent is all The side of light guide plate 1 is limited in, so as to which the light for allowing LED to send all enters in light guide plate 1.
In Fig. 2, the light after being reflected by reflective sheeting 4 can be got on the substrate of lamp bar 2 again, form secondary reflection, in order to More light are allowed to enter light guide plate 1, we can increase a new reflecting layer here, as best shown in figures 3 a and 3b, in the table of lamp bar 2 Cover last layer reflective sheeting 4, there will be the local hollow out of LED lamp bead 3, reflective sheeting 4 is all enclosed in remaining place, from this improvement But the center light extraction increase by 10% of panel light.The surface of lamp bar 2 is covered to reflecting paper or reflection white oil of upper high reflectance etc., But LED region is spilt.Cushion pad 9 is provided between lamp bar 2 and substrate.
On the basis of aforementioned structure, in order to allow light more to be transmitted in light guide plate 1 in the design of whole panel light, Such as Fig. 4, the side for not entering light of light guide plate 1 is blocked using reflective sheeting 4, it is therefore an objective to allow light not spilt from light guide plate 1, especially Light guide plate 1 is at the chamfering at four angles.The side for not entering light is blocked using reflecting paper or highly reflective material, prevents light from leading Tabula rasa 1 is spilt.
It can also strengthen reflection at diffuser plate 5 and metal frame overlapping region increase reflecting paper or high reflection material, reduce Light loss.Such as Fig. 5, diffuser plate 5 is blocked into part plus reflective sheeting 4 so that reaching aluminium by diffuser plate 5 by surrounding metal frame The light lost on frame reflects meeting diffuser plate 5 by reflective sheeting 4, and improves light taking-up.
Lamp bar 2 described in two groups is located on same metal framework 6, the metal framework 6 be a side opening arcuate structure, institute State light guide plate 1, lamp bar 2 and the reflective sheeting 4 to be enclosed in the metal framework 6, the diffuser plate 5 is located at the metal frame The side that frame 6 is open, the length of the diffuser plate 5 are more than or equal to the opening maximum of the metal framework 6.
Prismatic lens 7 can also be used, control panel lamp rising angle, so that light more to concentrate on to panel light front It is removed.As shown in fig. 6, by the rising angle of effective control panel lamp, that improves panel light goes out optical density.By traditional panel The mode that the diffuser plate 5 of lamp is substituted for the prismatic lens 7 plus transparency glass plate 8 that are covered with BEF films is carried out, so that light guide plate 1 is emitted Light more concentrates on panel light front so that the lighting angle of panel light diminishes, so that brightness increases, can be achieved>50% Lifting.
More than, although the description of several embodiments of the present utility model, but these embodiments are intended only as example It is proposed, be not intended to limit the scope of the utility model.For these new embodiments, can enter in a manner of other are various Row is implemented, and in the range of main idea of the present utility model is not departed from, can carry out various omissions, displacement and change.These are implemented Mode and its deformation, while being contained in the scope of the utility model and main idea, are also contained in described in claims In utility model and its equivalency range.
