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...

Examples

Embodiment Construction

[0015] The specific implementation of this patent will be described in detail below. It should be pointed out that this specific implementation is only an example of the preferred technical solution of this patent, and should not be understood as limiting the scope of protection of this patent.

[0016] Such as figure 1 As shown, this specific embodiment provides an eye-protecting LED lamp for classrooms, and the LED lamp includes: an LED chip 1, a lampshade 2 and a blue light reduction device.

[0017] In this specific implementation manner, the LED chip and the lampshade can be realized by adopting the structure of the prior art. A typical structure such as figure 1 As shown, the light-emitting chip 1 and the lampshade 2 are used to emit light for lighting under the drive of current, and the lampshade usually plays the role of fixing the structure of the LED lamp and guiding the lighting area of ​​the light. The top and side of the lampshade close the lower part to form an...
