Embodiment 1

[0064] A special light source suitable for diabetic retinopathy, the light source includes: a substrate, a yellow-green light bead and a far-red light bead, wherein the emission wavelength of the yellow-green light bead is 457nm-720nm, and the emission wavelength peak value of the yellow-green light bead is 555nm; the emission wavelength of the far-red lamp bead is 590-900nm, and the peak emission wavelength of the far-red lamp bead is 760nm.

[0065] The yellow-green light bead and the far-red light bead array are arranged on the substrate. The substrate is one or a combination of planar structure, curved surface structure, and special-shaped structure. The curved surface structure can be hemispherical, ellipsoidal, spherical, etc., and the special-shaped structure can be surface wavy, surface convex, etc. . Among them, the substrate is used to fix the yellow-green light beads and the far-red light light beads. The arrays of yellow-green light beads and far-red light light b...

Embodiment 2

[0076] In Embodiment 2 of the present invention, the yellow-green light beads are yellow-green light LED light beads, the far-red light light beads are far-red light LED light beads, and the substrate is a plate that fixes and supports the LED light beads and performs heat dissipation and heat conduction. The LED lamp beads and the yellow and green LED lamp beads are alternately arranged on the substrate. Different proportions of yellow-green LED lamp beads and far-red LED lamp beads are alternately arranged in an array on the substrate to produce lamps with different irradiances, meeting the requirements of human eyes for the brightness of visible light illumination.

[0077] Wherein, the manufacturing process of the far-red LED lamp beads includes:

[0078] Weigh the far-red phosphor, transparent silica gel A and transparent silica gel B, wherein the mass ratio of transparent silica gel A to transparent silica gel B is 1:1, and the far-red phosphor accounts for 10% of the to...

Embodiment 3

[0086] Embodiment 3 of the present invention differs from Embodiment 2 in that Y(Al 0.96 Cr 0.04 ) 3 (BO 3 ) 4 Encapsulating LED chips to make far-red LED lamp beads, the Y(Al 0.96 Cr 0.04 ) 3 (BO 3 ) 4 The preparation process includes: using Al 2 o 3 、H 3 BO 3 and Cr(NO 3 ) 3 9H 2 O is the raw material, according to the chemical formula Y(Al 0.96 Cr 0.04 ) 3 (BO 3 ) 4 Weigh each raw material, put it into a corundum crucible after fully grinding, burn it at 500°C for 2 hours in the atmosphere, take it out and grind it again, and then carry out secondary calcination at 1250°C for 4 hours, after being out of the furnace, grind it and wash it several times. Y(Al 0.96 Cr 0.04 ) 3 (BO 3 ) 4 .

[0087] Using Y(Al 0.96 Cr 0.04 ) 3 (BO 3 ) 4 The far-red LED lamp bead encapsulated by phosphor powder is marked as LED-2. Figure 17 The emission spectrum of the far-red LED-2 lamp bead and its comparison with the absorption spectrum of HeLa cells are given. ...

Abstract

The invention discloses a special light source and a lamp suitable for diabetic retinopathy. The light source includes: a substrate, a yellow-green light bead and a far-red light bead, wherein the yellow-green light bead and the far-red light bead are arranged in an array On the substrate; the light fixture includes: a control power supply and a lampshade, the control power supplies power for the yellow-green lamp beads and the far-red lamp beads; the lampshade covers the substrate, the yellow-green lamp beads and the far-red lamp beads inside; the advantage of the present invention is that : A special lamp light source that takes into account both the home life lighting of diabetics and the prevention and treatment of diabetic retinopathy.

Description

technical field [0001] The invention relates to the field of health lighting, and more specifically relates to a special light source and a lamp suitable for diabetic retinopathy. Background technique [0002] The penetration rate of white LEDs in household lighting is already close to 70%, and it is expected to reach 100% in 2025, but the currently used white LEDs are rich in blue light and lack far-red light. The hazards of LED blue light have been known to everyone. Because LED blue light can easily cause damage and apoptosis of retinal cells and optic neurons, white LED lighting is especially not suitable for diabetics. [0003] Diabetic retinopathy is one of the four causes of blindness in humans. Diabetic retinopathy (DR) is one of the serious complications of diabetes, accompanied by symptoms such as hard exudates, bleeding spots, cotton wool spots, and macular edema. It leads to vision loss or even blindness in diabetic patients, which seriously affects the visual ...
