Abstract
An LED lamp bead, comprising: the LED lamp comprises a first blue light LED chip and a second blue light LED chip, wherein the first blue light LED chip and the second blue light LED chip are arranged on a substrate in an LED lamp bead in parallel, and fluorescent powder is coated on the surface of the first blue light LED chip and the surface of the second blue light LED chip. The application provides a pair of LED lamp pearl uses two kinds of wavelength chips to arouse phosphor powder, can drop harmful blue light to safety range effectively in, solves the technical problem of harmful blue light to people's eyes injury among the current illumination field technique.
Description
Technical Field
The utility model belongs to the technical field of LED lamp pearl, concretely relates to LED lamp pearl.
Background
In indoor illumination, the LED white light bead uses a blue light chip with the wavelength of 450-460nm to excite fluorescent powder to obtain a mixed spectrum so as to realize the emission of white light. Since the 450-460nm blue light chip contains the blue light with the wavelength of 400-440nm which is harmful to the eyes, the eyes can be damaged by using the light source as illumination for a long time.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a LED lamp pearl, include: the LED lamp comprises a first blue light LED chip and a second blue light LED chip, wherein the first blue light LED chip and the second blue light LED chip are arranged on a substrate in an LED lamp bead in parallel, and fluorescent powder is coated on the surface of the first blue light LED chip and the surface of the second blue light LED chip.
Preferably, the phosphor is an aluminate phosphor.
Preferably, the aluminate phosphor is a green aluminate phosphor.
Preferably, the wavelength of the first blue light LED chip is 450-460nm, and the wavelength of the second blue light LED chip is 465-475 nm.
Preferably, the wavelength of the first blue light LED chip is 465-475nm, and the wavelength of the second blue light LED chip is 450-460 nm.
The application provides a pair of LED lamp pearl uses two kinds of wavelength chips to arouse phosphor powder, can drop harmful blue light to safety range effectively in, solves the technical problem of harmful blue light to people's eyes injury among the current illumination field technique.
