LED light source for reducing harm of blue light based on purple light chip

Abstract

The invention discloses an LED light source for reducing the harm of blue light based on a purple light chip. The LED light source comprises a lead support, the inner surface of the lead support is coated with a silver plating layer, the inner bottom end of the lead support is provided with a purple light chip, and the interior of the lead support is filled with fluorescent glue, the two side surfaces and bottom surface, which are attached to the fluorescent glue, of the lead support are respectively coated with a vulcanization liquid layer. According to the LED light source for reducing the harm of blue light based on the purple light chip, when the LED light source emits light, the light source is enabled to generate a continuous spectrum close to the natural light, the spectrum is full,the color of the light source is soft, and the ratio of the short-wave high-energy blue light of the LED light source is less than 50%; through scientific spectral adjustment, the short-wave blue light is reduced so as to achieve the effect of protecting eyes, and meanwhile, the long-wave blue light is increased, so that the visual fatigue can be effectively relieved, and the people can keep thestate of being awake and alert; and the whole LED light source has the characteristics of high color rendering performance, high color fidelity and high color saturation.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED light source, and more specifically to an LED light source for reducing the harm of blue light based on violet light chip excitation. Background technique [0002] With the deepening of people's research on semiconductor light-emitting materials, the continuous progress of LED manufacturing technology and the development and application of new materials, breakthroughs have been made in ultra-high brightness LEDs of various colors, and their luminous efficiency has increased by nearly 1000 times. In terms of brightness, all colors in the visible light band have been realized, the most important of which is the emergence of ultra-high brightness white LEDs, making it possible for LED applications to leapfrog to the high-efficiency lighting source market, but there are still certain deficiencies in the use of LED light sources. It is believed that there will be f...

Problems solved by technology

[0003] At present, the most common LED light source is to use the blue light emitted by the blue chip to excite the phosphor powder to emit yellow-green light or yellow-green, red light, and then mix with the remaining blue light of the chip to form white light. There will be a blue light peak below 500nm in the spectrum, usually at 445-455nm. Considerable power intensity, due to the high-energy blue light spectrum range of 415-455nm, such a light-emitting mechanism hides the problem of eye hazards. The traditional method is to reduce the color temperature of the light source. Although the blue light radiation energy of the low-color-temperature white LED light-emitting mechanism is very low, The harm of blue light is very small, but the color temperature is too low, the color temperature is too low, it will cause inattention, fatigue and sleepiness
