For this reason, the utility model is taked following scheme: a kind of LED light mixing device, comprise light emitting module, it is characterized in that also comprising LGP, described light emitting module comprises substrate, and at least two kinds of monochromatic LED light sources are housed on the substrate, described light emitting module is arranged on the side of LGP, the light emission direction of led light source forms uniform indentation or reflection site towards LGP on the lower panel of described LGP, the top panel top of described LGP is provided with diffusion barrier.Led light source is set in parallel in a side of corresponding LGP, and is not contained in LGP inside, can effectively reduce the thickness of light mixing device, meets slimming trend; The light part that led light source sends is directly launched from the top panel of LGP, a part is totally reflected to the lower panel of LGP through top panel, light after this part total reflection and led light source directly are mapped to the light on the LGP lower panel, the top panel of LGP reflexed to again by the reflector space of LGP lower panel formation indentation and site, scattering takes place in all after the light that the LGP top panel penetrates is mapped to diffusion barrier, form mixed light.The part light that LED sends through reflection repeatedly, mixes all kinds of not homochromy led light sources before arriving diffusion barrier fully, has improved the uniformity of mixed light.In the mixed light process, light has only small part to penetrate from other exiting surface of LGP, has improved light emission rate.
The lower panel below of described LGP is provided with reflecting piece.The material that reflecting piece adopts PET or surface to be coated with high reflected coat layer is made, and the light that can be effectively part be penetrated from the LGP lower face is again in the reflected back LGP, the minimizing light losing.
The top of described diffusion barrier is provided with light-passing board, and light-passing board can allow the light behind the mixed light be tending towards evenly, is beneficial to heat insulation, cooling, also can obtain good decoration effect.
Described monochromatic LED light source is White LED, red LED, blue led or green LED, and led light source by three primary colours and white light source can modulate the nearly all saturated color in the cie color curve.
Described each monochromatic LED light source is disposed on the substrate, makes the mixed light effect that reaches more even.
Described LGP is a cuboid, and the two or more sides of described LGP are provided with light emitting module, and the mixed light effect is more even, and can not increase the thickness of light mixing device.
The material of described making LGP is PMMA, COP or PC, and these a few class materials have the good optical characteristic, the light emission rate height.
The thickness and the substrate thickness of LGP are suitable.
The beneficial effects of the utility model are embodied in: 1. light emitting module is arranged on a side of the thickness LGP suitable with it, is covered with diffusion shell relatively thereon, has reduced the integral thickness of light mixing device, meets slimming trend; 2. the LGP by following strip site or indentation changes the transmit direction of partial L ED light source, avoids light to send and cause damage from the LGP lower panel, has improved light emission rate; 3. part light penetrates from the LGP top panel through reflection back repeatedly in LGP, forms scattering through diffusion barrier again, during effectively increased the light mixing distance of led light source, mixed light is more even.
