Detailed Description

In order that the invention may be more readily understood, a more particular description of the invention will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

As shown in fig. 1 to 7, in the present embodiment, an optical structure of an interactive lamp is provided, which is mainly composed of a bracket 4, an LED module, an inner lamp cover 5, a decorative ring 6, and the like. Wherein, the LED module comprises FPC soft board 2, drive plate 1 and a plurality of LED3, and FPC soft board 2 assembles on support 4 and is crooked arranging, and drive plate 1 and a plurality of LED3 set up respectively in FPC soft board 2's both ends position. The bracket 4, the FPC board 2, the inner lampshade 5 and the decorative ring 6 are sequentially arranged and are connected and fixed in a mode of screw assembly, clamping assembly, riveting assembly and the like. Specifically, the FPC flexible board 2 in the present embodiment is divided into an LED area 24 for arranging the LEDs 3, a soldering area 22 for mounting the driving board 1, and a connection area 23 bent and folded between the LED area 24 and the soldering area 22, and a plurality of solder joints 21 are further provided on the soldering area 22 for solder communication with the driving board 1. The design is that the FPC flexible board 2 is used as a base board of the LED module, and can be shaped along with a molding surface to the greatest extent during arrangement, can be bent and folded, saves space and has attractive appearance; the FPC flexible board 2 can be directly welded and communicated with the driving board 1 without wire harness connection, so that space is saved, and the assembly process is simplified. The LED area 24 of the FPC flexible board 2 can be a micro-curved surface modeling, and the curved surface can follow the curved surface of the inner lampshade 5 and the decorative ring 6, so that the emission angle of each individual LED3 light is ensured to be consistent with the normal angle of the surfaces of the lampshade 5 and the decorative ring 6 in the area, and the lighting effect of better front view observation is achieved when the lamp is observed in multiple angles and multiple views. The conventional FR4 hard board can only enable the LED light-emitting angle on the plane to be consistent, but cannot follow the shape of a modeling curved surface, so that the phenomenon of uneven brightness occurs when the board is observed at multiple angles; meanwhile, compared with an FR4 hard board scheme, the depth size of the lamp in the emergent direction of the LED is reduced by the FPC scheme, so that the structure of the lamp is simpler, the weight of the whole lamp is reduced, and the light-weight design is realized.

Specifically, referring to fig. 1-5, the inner lampshade 5 in this embodiment is composed of a black sheet 52 that is tightly attached to the FPC film 2 and a white sheet 51 that is embedded in the end of the black sheet 52, and a plurality of accommodating cavities 100 that surround the LEDs 3 are formed between the white sheet 51, the black sheet 52 and the FPC film 2, and the accommodating cavities 100 are in one-to-one correspondence with the LEDs 3. The white sheet 51 and the black sheet 52 may be a combination of materials, that is, two material parts are formed by one-time molding and injection molding through a mold, or two-time molding with one component after injection molding is completed; the white sheet 51 and the black sheet 52 may be force-combined, that is, the white sheet 51 and the black sheet 52 are assembled by clamping, riveting, welding, or the like.

More specifically, the black sheet 52 of the present embodiment is a substrate 520, a plurality of notches 5201 constituting all the accommodation cavities 100 are formed in the substrate 520, the notches 5201 are rectangular, the substrate 520 is fitted closely to the FPC board 2, and each notch 5201 encloses one LED3. Limiting steps 521 distributed in a staggered manner are formed around the notch 5201 of the substrate 520, a space is reserved between adjacent limiting steps 521, meanwhile, a limiting opening 510 corresponding to the limiting step 521 is formed in the white piece 51, and the white piece 51 is clamped and embedded on the end face of the notch 5201 of the black piece 52 through the matching of the limiting opening 510 and the limiting step 521. The height of the limiting step 521 is consistent with the thickness of the white piece 51, so that the surface of the white piece 51 and the black piece 52 after being combined is flush. Of course, the white sheet 51 is made of a diffusion material, the light transmittance is 10% -80%, and the black sheet 52 is made of a non-light-transmitting material. In this way, the black sheet 52 serves as a surrounding barrier, each LED3 is located in one accommodating cavity 100, and a single LED3 is surrounded by the wall of the notch 5201 of the single black sheet 52, which is equivalent to shielding from the source of light emergent light, and the white sheet 51 also forms a good covering seal due to auxiliary shielding of the surrounding limiting steps 521, so that light channeling between adjacent LEDs 3 can be prevented when light is emitted. It can be understood that the single LED3, the single notch 5201, the limit step 521 and the white piece 51 corresponding to the single accommodating cavity 100 form a light emitting unit, after the LED3 corresponding to the unit structure is lighted, the white piece 51 in the area is lighted at the same time, and the brightness of the surrounding white piece 51 is not affected, so that the final light emitting effect is uniform, the brightness is bright, and a certain LED3 or certain LEDs 3 can be controlled to emit light independently, so that more combined use experiences can be provided, and the functions can be diversified. Of course, the shape of the notch 5201 may be various other shapes, that is, the final light emitting unit structure may be a quadrangular body, a triangular body, or other polygonal bodies.

Specifically, referring to fig. 1, 2 and 6, the decorative ring 6 in this embodiment is composed of a transparent layer 61 and an opaque layer 62 near the light-emitting surface of the white sheet 51, the transparent layer 61 and the opaque layer 62 are made of a material, the transparent layer 61 is made of a transparent material, the light transmittance is 60% -100%, and the opaque layer 62 is made of an opaque material. As shown in fig. 6, the light-transmitting layer 61 and the light-impermeable layer 62 are staggered, and the light-transmitting layer 61 has a plurality of light-transmitting blocks 610 distributed at intervals, and the light-transmitting blocks 610 are also rectangular when viewed from the outside, and each light-transmitting block 610 is located in the light-emitting direction of the LED3 and corresponds to the LED3 one by one, that is, each light-transmitting block 610 corresponds to one light-emitting unit. The light emitted by the single LED3 is emitted through the white sheet 51 and then enters the light-transmitting layer 61 to be emitted from the single light-transmitting block 610, and the outer surface of the light-transmitting block 610 is provided with optical patterns so as to change the light emitting angle and direction and improve the lighting uniformity. It can be appreciated that the opaque layer 62 also acts as a molding barrier, so as to improve the final light-emitting effect and ensure light-emitting uniformity; each LED3 corresponds to a light emitting unit and a light transmitting block 610, and in the light path emergent process, independent control can be realized by means of separation and blocking of the notch 5201, the limiting step 521 and the light-tight layer 62, so that particles are refined, and the light modeling effect is more vivid and diversified.

It should be noted that, referring to fig. 1 and 2, the width of the interval between the adjacent transparent blocks 610 is larger than the width of the interval between the adjacent notches 5201 in the present embodiment, i.e. c > a in fig. 2, and the width of the transparent blocks 610 gradually decreases from the side close to the transparent layer 61 to the side far from the transparent layer 61. As the key of the opaque layer 62, the size of c is the opaque portion, which plays a role of shielding the internal structure of the bezel 6, and the maximum size of c means that the shielding structure of the internal black sheet 52 can be hidden, and when viewed at multiple angles, only the portion of the size of c of the opaque layer 62 with the maximum size range can be seen, so that the central lighting area is ensured to be uniform and integral. In addition, the width of the light-transmitting block 610 near the light-transmitting layer 61 in this embodiment is larger than the width of the notch 5201, that is, e > d in fig. 2. So can make the light after the light-emitting unit diffusion adopt wide angle, on a large scale, fully go into the printing opacity piece 610 to make the light quantity of printing opacity piece 610 maximize, carry out secondary angle diffusion through the optics decorative pattern of printing opacity piece 610 again, the overall effect is more even after lighting, and the luminance difference between every light-emitting unit is minimum.

Of course, the notch 5201, the light-transmitting block 610, and the individual light-emitting units involved in this embodiment are all rectangular in shape. In other embodiments, the light-emitting device can be in various shapes, can be in a uniform shape or pattern, can be a combination of patterns in different shapes, and also adopts the structure, so that the final light-emitting effect is uniform, the brightness is vivid, more combined use experiences are provided, and the functions are diversified. Referring to the example shown in fig. 8, this is a view of the effect of light emission that can be observed from the outside as a whole for light emitting units of various shapes, with distinct gradation particles, no influence of light and shade between adjacent light emitting units, and light emission alone or as a whole.
