Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Embodiment 1

Referring to Fig.1-2, a kind of by the illuminating module that plastics appearance is electroplated and LED light source and pcb board group are closed, including plated item 1, LED and pcb board 2, wire rod 3 and plastic cement bottom cover 4, the wire rod 3 are welded on LED and PCB plate 2,1 upper end of plated item It is electroplate with metal layer, the LED and pcb board 2 are equipped with lamp bead mounting hole, and the plated item 1 is fixed on plastic cement bottom cover 4, electricity Plating piece 1 is fixed with plastic cement bottom cover 4 by buckle or fastening screw；The LED and pcb board 2 are located at plastic cement bottom cover 4 and plated item 2 It in the cavity of formation, and is fixedly connected with plastic cement bottom cover 4, the wire rod 3 passes through plastic cement bottom cover far from one end of LED and pcb board 2 4, and it is in the outside of plastic cement bottom cover 4.

Material material used in plated item is PC plastic, light transmittance 80%, cloudy surface 95% or so, plated item surface electricity The material of plating is metallic aluminium, and plating color is rifle color, and the light transmittance of plated item can be adjusted by adjusting the thickness of electroplated layer； LED determines that plastic cement bottom cover integral thickness is 10mm in the embodiment, for lamp on Y shape shape luminous zone on guarantee plated item and pcb board The quantity of pearl can be uniform by the height domain of plastic cement bottom cover entirety, uses 3 LED lamp beads, lamp bead model 2835RGB.

There are many fixed forms of LED and pcb board and plastic cement bottom cover, can be fixed by screws on LED and pcb board Plastic bottom covers, is fixed on LED and pcb board and the fixation of plastic cement bottom cover hot melt or LED and PCB backboard face paste double-sided adhesive Plastic bottom covers.

Wire rod is the electrified wire of LED and pcb board, and wire rod needs two when LED bill coloured light, and LED can when sending out polychromatic light Select three or four conducting wires.

Plastic cement bottom cover uses the opaque material of black ABS.

Under the conditions of LED is non-luminous, in the case that plated item appearance shows that the metallic luster of rifle color, LED shine, plating Part output optical zone domain shows the luminous color of LED, the Technical Design and low manufacture cost, the uniform brightness of mould group light efficiency Greatly.

Embodiment 2

With reference to Fig. 3-4, for the utility model proposes another plastics appearance is electroplated and LED light source and pcb board group are closed Illuminating module, light guide plate 7, the 7 upper end viscose glue of light guide plate are additionally provided between the LED and pcb board 2 and the plated item 1 There is diffusion barrier 6, the 6 upper end viscose glue of diffusion barrier has anti-dazzling screen 5, and the light guide plate 7 and LED and pcb board 2 are fixed by viscose glue.

Anti-dazzling screen in the embodiment, using one face black of one side silver color, wherein black one side is with diffusion barrier viscose glue one It rises, silver color face is for reflective, and effect has two o'clock: first is that being screened off to the stray light launched outward at light source；Second is that reflective portion is miscellaneous Astigmatism increases the utilization rate of optical system, the model 3806RGB of lamp bead used in the embodiment.

The effect of diffusion barrier is for making the light-emitting surface of light guide plate more evenly, and the light transmittance of diffusion barrier is 80% or so, thick 0.1mm is spent, back patch double-sided adhesive is fixed with light guide plate combination, and light guide plate is uniformly projected from light-emitting surface for conduction light, is led Tabula rasa back side arrangement site is used to adjust the uniformity of light-emitting surface.Guide-lighting back is also by patch double-sided adhesive and LED and pcb board group It closes and fixes, wherein LED and pcb board use white as far as possible, and effect is the utilization rate of light beam of adding lustre to.If LED and pcb board are realized Not white, needs to increase between light guide plate and LED and pcb board reflectance coating, reflectance coating reflecting rate 90%, with a thickness of 0.1mm, It will increase the corresponding cost and mould group thickness of optical mode group with better reflex.

Spatial depth required for the embodiment is lower, can be placed under very thin space, and is able to achieve out light light efficiency Uniformly, but production cost is higher relative to embodiment 1, and brightness is lower under equal conditions.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
