Detailed description of the invention

Set forth some detail in the following description to provide the thorough understanding of the various aspects to subject content of the present disclosure.But still can realize subject content of the present disclosure when not having these details.In some instances, not yet the known features forming the structure associated with surface mounting technology and method is specifically described, in order to avoid the description of the fuzzy other side to present disclosure.

Unless the context otherwise requires, otherwise description and appended claims in full in, word " comprises " being construed to and openly comprises meaning, that is, is interpreted as " including but not limited to ".

Quote " embodiment " or " embodiment " in this specification and mean that special characteristic, structure or the characteristic described in conjunction with this embodiment is contained at least one embodiment.Therefore, occur that expressing " in one embodiment " or " in an embodiment " may not all refer to identical aspect in this specification everywhere.In addition, can present disclosure one or more in combine special characteristic, structure or characteristic in any appropriate manner.

Referring now to Fig. 1, Fig. 1, show a typical case of the application scenarios according to illuminator of the present disclosure.Such as, Fig. 1 shows a room in building, places a desk in the middle of room, and the wall in room and ceiling are provided with multiple according to illuminator 10 of the present disclosure, multiple illuminator 10 launches light 11 respectively to illuminate indoor.

See an embodiment of the illuminator 10 in the scene that Fig. 2, Fig. 2 show such as shown in Fig. 1.Such as, illuminator 10 comprises the ground floor 22 with first surface 2201 and the second surface 2202 relative with first surface 2201, is embedded with at least one cavity 13 in ground floor 22.Each cavity 13 can extend to second surface 2202 from first surface 2201, and has at least one light source in each cavity 13.Light source can comprise at least one LED12.The light 11 that at least one LED12 sends is inciding the back surface of the second layer 21 to the direction of first surface 2201 via cavity 13 from second surface 2202, and a part of light wherein penetrates the second layer 21 outgoing.The major part incided in the light of first surface 2201 is reflected back toward the surface portion of the sidewall of ground floor 22 and the crossing with cavity 13 of third layer 23, and this causes light outgoing efficiency lower.

In order to solve or alleviate this problem, in the example shown in Fig. 2 of the present disclosure, the sidewall of the cavity 13 of ground floor 22 arranges reflecting layer, or the sidewall of the cavity 13 of ground floor 22 is formed as reflective side walls, this makes light be reflected back the back surface of the second layer 21 of such as wallpaper and so on to provide the exitance of light.Preferably, the surface portion crossing with cavity 13 of third layer 23 also has reflecting layer or is set to reflecting surface.

When light source comprises the LED12 of multiple different colours, light-mixing element can be set in LED12 front.In addition, when light source comprises the LED12 of multiple different colours, also the LED12 of multiple different colours can be made controlled with in the different color of different time showings, thus user can see that when illuminator works the bias light of different colours is to obtain further aesthetic.Although the cross section of cavity 13 is depicted as rectangle in fig. 2, but it will be appreciated by those skilled in the art that, cavity 13 can be other shape, such as trapezoidal, and the line that wherein second surface 2202 is crossing with trapezoid cross section is shorter than the line that first surface 2201 intersects with trapezoid cross section.Alternatively, distance from first surface 2201 to second surface 2202 is shorter, under the flexible situation had to a certain degree at the second layer 21 like this, maximum longitudinal direction (direction vertical with the first surface 2201) deformation that the second layer 21 causes when stressed can equal the distance between first surface 2201 and second surface 2202, and now the second layer 21 does not break, afterwards when the second layer 21 is no longer stressed, the second layer 21 can restore to the original state.In other words, the maximum flexibility deformation of the distance equaled between first surface 2201 and second surface 2202 of the second layer 21 does not make the second layer 21 break.Therefore, the shorter distance (it equals above-mentioned maximum longitudinal elasticity deformation) between first surface 2201 and second surface 2202 can reduce the probability that the second layer 21 is punctured.Alternatively, cavity 13 surface area crossing with the second layer 21 is less, this also can reduce the probability that the second layer is punctured, such as this surface area can be less than the contact area of finger and wallpaper, the power that such finger applies can be transmitted by ground floor 22, and the stressed caused deformation of the part contacted with cavity 13 of the second layer 21 is less, and therefore, this also can reduce the probability that the second layer 21 is punctured.。

In the figure 2 example, ground floor 22 can be such as dry plate, the plank etc. of such as plasterboard, acoustic board, medium density fibre board (MDF), engineering design.The second layer 21 can be such as wallpaper, emulsion layer etc.Third layer 23 can be such as medium density fibre board (MDF), plank etc.More than illustrating is only example, and unrestricted.In each embodiment of the present disclosure, ground floor 22, the second layer 21 and third layer 23 can be manufactured from the same material, and also can be made up of different materials.
