Embodiment Construction

[0027] like figure 1 and figure 2 As shown, the present invention provides a LED that reduces blue light hazards, including a bracket 1, a blue light chip 2, a fluorescent glue layer 3 and an anti-blue light material layer 4, the blue light chip 2 is arranged on the bracket 1, and the fluorescent glue layer 3 covers For the blue light chip 2 , the anti-blue light material layer 4 is covered on the fluorescent adhesive layer 3 . The blue light emitted by the blue light chip 2 and the fluorescent powder first excite the mixed white light, and then completely absorb part of the spectrum of blue light through the anti-blue light material layer 4 arranged above it, and the white light produced by the LED is still white light with the required color temperature. The blue light material layer 4 only absorbs part of the blue light spectrum in the LED, without affecting the transmission of other necessary white light spectra by its entire structure.

Abstract

The invention provides an LED capable of reducing blue light harm, and the LED comprises a support, a blue light chip, a fluorescent glue layer, and a blue light prevention material layer. The blue light chip is disposed on the support, and the fluorescent glue layer covers the blue light chip. The blue light prevention material layer covers the fluorescent glue layer. The LED provided by the invention can reduce the harm of blue light, cannot cause color cast, and is simple in structure. The invention also provides the blue light prevention material layer, and the blue light prevention material layer contains a UV-resistant agent, titanium dioxide and silica gel, wherein the weight ratio of titanium dioxide is 0.5%-3%, the weight ratio of the UV-resistant agent is 2%-4%, and the weight ratio of the silica gel is 93%-97%. The blue light prevention material layer provided by the invention can absorb the blue light spectrum, and does not affect the transmission of other spectrums.

Description

technical field [0001] The invention relates to an LED and an anti-blue light material layer which reduce the harm of blue light, and belongs to the technical field of LEDs. Background technique [0002] Medical research reports have shown that violet and blue light in visible light have the greatest damage to the retina. Visible light with a wavelength of 500-800 has basically no damage to the retina, while the violet and blue light with a wavelength of 400-500 increases with the decrease of the wavelength and the increase of photon energy, and the degree of damage to the retina rises rapidly. At the time, the mechanisms of how blue light damages the retina were not well understood. Therefore, it has not received much attention from the ophthalmology community. In the past two or three years, scientists have only begun to realize that retinal cells contain an abnormal retinal called A2E. A2E has two absorption peaks: one is 335NM in the ultraviolet region; the other is 43...
