Abstract

The invention discloses a full-spectrum LED lamp bead which comprises a light-emitting chip, a support used for containing the light-emitting chip and fluorescent glue used for packaging the light-emitting chip and allowing light emitted by the light-emitting chip to be transmitted and emitted out. The light-emitting chip comprises a blue light chip and a purple light chip. The wave band of the blue light chip is 440 nm to 470 nm, and the wave band of the purple light chip is 400 nm to 420 nm. The fluorescent glue is formed by mixing silica gel or epoxy resin glue with fluorescent powder. Thefluorescent powder comprises red fluorescent powder, yellow-green fluorescent powder and blue fluorescent powder. The excitation wave band of the red fluorescent powder is 615 nm to 660 nm, the excitation wave band of the yellow-green fluorescent powder is 520 nm to 540 nm, and the excitation wave band of the blue fluorescent powder is 445 nm to 455 nm. The lamp bead has the advantages of low energy consumption, high color rendering index and high brightness, is more beneficial to human health and environment, and is closer to sunlight.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, in particular to a full-spectrum LED lamp bead. Background technique [0002] LED (Lighting emitting diode) lighting technology has been welcomed for its high luminous efficiency, good shock and earthquake resistance, high reliability, long life, and easy adjustment, and has become a widely used lighting technology. However, the conventional LED light source is a point light source with a narrow spectrum, and its peak wavelength is between 450 and 460nm, which is very different from the sunlight spectrum. However, the special structure of the human eye and the long-term living environment of human beings determine that human beings can read and observe in sunlight. The eye has the highest sensitivity, and to make the human eye feel comfortable in a certain lighting environment, it needs to make its luminous spectrum close to the sunlight spectrum. [0003] The current white light LED mainly...
