An eye-protecting led lamp for classrooms

Abstract

The invention discloses a classroom-used eye-protecting LED lamp, which comprises a lampshade and an LED chip, and is characterized by further comprising a blue light reduction device, wherein the blue light reduction device reduces blue light with the wavelength of 400 to 450 nm and yellow light complementary to the blue light with the wavelength. Projection of light with different wavelengths todifferent positions is achieved under effects of light splitting of prisms, and the blue light and the yellow light complementary to the blue light are reduced at the same time. Thus, the eyesight can be prevented from being hurt by the blue light, the color balance of a light source can be kept, and color rendering of the light source is ensured.

Description

technical field [0001] This patent belongs to the technical field of teaching equipment, and specifically relates to an eye-protecting LED lamp for classrooms. Background technique [0002] LED light sources have been widely used in various fields in the prior art, and have been recognized by the market for their advantages of energy saving and environmental protection. LED lamps have been widely used for lighting in the prior art. In the prior art, LED lights have been widely used in enterprises, education and other fields. It is a common lighting device. [0003] However, when used in the field of education, due to the generation of blue light when LED equipment emits light, this will have a negative impact on the eyesight of children, so the damage to vision caused by LED lights cannot be ignored when used. In the field of LED lights, the method of adding a blue light filter mask is often used to filter out blue light, but this method usually directly removes blue ligh...

Problems solved by technology

[0003] However, when used in the field of education, due to the generation of blue light when LED equipment emits light, this will have a negative impact on the eyesight of children. Therefore, the damage to vision caused by LED lights cannot be ignored when they are used.

In the field of LED lights, the method of adding a blue light filter mask is often used to filter out blue light, but this method usually directly removes blue light, which will cause the color rendering of the light source to be yellowish, and in addition to reducing blue light, it will also reduce other colors. light, so it will affect the color rendering effect, as well as the brightness of the lighting
