Problems solved by technology

[0008] As mentioned above, in order to realize white light, blue light-emitting diode chips are used, so blue light has a high peak in the wavelength of the blue band, and there is a problem that the retinal cells in the vitreous body of the human body are damaged or affected by the blue light. The human body secretes cortisol or melatonin and has a high risk of insomnia or mental disorders such as bipolar disorder
However, since the strength of methyl-based silicon is lower than that of phenyl-based silicon, there is a problem of reduced reliability

Abstract

The invention relates to a light emitting device. The light emitting device according to an embodiment of the invention comprises: a blue light emitting portion that emits blue light; a green light emitting portion that emits green light; and a red light emitting portion that emits red light, wherein a triangular region defined by color coordinates of the blue light emitting portion, the green light emitting portion, and the red light emitting portion comprise at least part of Planckian locus therein, a color temperature can be regulated by regulating the brightness of light emitted from the blue light emitting portion, the green light emitting portion, and the red light emitting portion.

Description

[0001] This application is a divisional application of the invention patent application "light-emitting device" with the filing date of March 27, 2019 and the application number of 201980000931.2. technical field [0002] The present invention relates to a light emitting device, and in more detail, relates to a light emitting device that can use a light emitting diode as a light source and be used in lighting equipment. Background technique [0003] Most living organisms on earth are adapted to move according to changes in sunlight. The human body has also adapted to sunlight for a long time. According to this, the body rhythm of the human body is thought to change in response to changes in sunlight. Especially, in the morning, under the bright sunlight, the human body will secrete cortisol (Cortisol) hormone. The cortisol hormone increases the blood supply to the various organs of the body in response to external stimuli such as stress, and thus causes the pulse and respi...
