Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, a natural light LED packaging structure includes a substrate 2 mounted on the bottom of the packaging case 1, an LED chip 3 disposed on the substrate 2, a phosphor layer 4 disposed on the LED chip 3, and a packaging glue Layer 5 is characterized in that it also includes a polarizing film 6 arranged above the phosphor layer 4, a polarizing reverse film 7 disposed above the polarizing film 6, and the encapsulation adhesive layer 5 is disposed on the polarizing reverse film 7 above; the polarizing film 6 is polarized in the 435nm band; the anti-polarizing film 7 is polarized in the 475nm band; both the polarizing film 6 and the anti-polarizing film 7 adopt a grating structure.

[0019] In another embodiment of the present invention, the polarizing film 6 is polarized in the 440nm band; the reverse polarizing film...

Abstract

The invention relates to the field of LED packaging, and specifically discloses a natural light LED packaging structure. The natural light LED packaging structure comprises a substrate mounted at thebottom of a packaging shell, an LED chip arranged on the substrate, and a fluorescent powder layer and a packaging adhesive layer both arranged on the LED chip. The natural light LED packaging structure is characterized by further comprising a polarization film arranged over the fluorescent powder layer, and a reverse polarization film arranged over the polarization film, wherein the packaging adhesive layer is arranged over the reverse polarization film. The polarization film reflects a blue light constituent emitted by the fluorescent powder layer, thus, emitting out of the blue light is reduced, and harm to human eyes is reduced; with the polarization film, trough light effect in light spectrum is improved, meanwhile, the light effect of other wave bands is reduced; and simultaneously,with the reverse polarization film, transmissivity of visible light of the trough wave band in the light spectrum is improved further, the trough is filled, spectrum of the visible light is smooth, and the light spectrum is adjusted to have better continuity.

Description

technical field [0001] The invention relates to the field of LED packaging, in particular to a natural light LED packaging structure. Background technique [0002] The blue light component in the spectrum of the LED light source that is being promoted at this stage is extremely harmful to the eyes. The World Health Organization (WHO) Eye Society has issued a report in 2008. At that time, 30,000 people around the world were blinded every year due to blue light radiation. The association issued an orange warning at the end of 2009: "The potential threat of blue light radiation to humans will far exceed the destructiveness of Sudan red, melamine, SARS, and HINI, and it will swallow people's eyes virtually." Children, teenagers, and adults with delicate eyes People who use electronic products for a long time are more vulnerable to blue light damage. The eyes of infants and young children are the most vulnerable to blue light damage. Because the baby's lens is relatively clear,...
