Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lighting lamps and lanterns especially relates to a high color temperature high illuminance's desk sunlight lamp. BACKGROUND

[0002] The desk lamps on the market are relatively single in lighting function, and cannot meet the needs of efficient work and study lighting and comfortable rest atmosphere creation at the same time. Most lamps cannot effectively inhibit the secretion of melatonin to improve work and study attention, and lack flexibility and pertinence in environmental light creation, which is easy to produce glare and affect the use experience.

[0003] The following related researches provide reference for inhibiting the secretion of melatonin to improve work and study attention.

[0004] 1. "Art Gallery Work Artificial Light Environment Research under the Emotional Response of the Observer": This research objectively studies which light environment is more likely to attract the interest of the observer when the observer appreciates the paintings in the art gallery by means of the data from the eye tracker. The experimental results show that only the total fixation time and the number of visits in the interest area are significantly related to the light environment. The increase of color temperature and illuminance can increase attention. Under the condition of high illuminance and high color temperature, it is the most suitable optical index for the observer to appreciate the paintings in the art gallery.

[0005] 2. "Effects of correlated color temperature on focused and sustained attention under white LED desk lighting": This research examines the effect of correlated color temperature (CCT) on focused and sustained attention under white LED desk lighting. The results show that the focused and sustained attention is significantly better under the condition of 4300K, but it also points out that the specific effect of high illuminance and high color temperature light combination on attention is not explicitly mentioned. However, this research provides a reference for understanding the effect of different color temperatures on attention.

[0006] 3, "Effect of correlated color temperature and illuminance on sustained attention collected via electroencephalography signals", 10: This study aims to explore the effects of nine lighting conditions of three commonly used correlated color temperatures (3300K, 4300K, 5300K) and illuminance levels (300lx, 500lx, 750lx) on the sustained attention of subjects. The study found that as the color temperature increases, the attention level tends to increase linearly, and the attention level is highest at 500lx, showing an inverted "U" shape. Although it does not directly indicate that the combination of high illuminance and high color temperature of the light will necessarily improve attention, it provides important data for understanding the effects of different color temperature and illuminance combinations on attention.

[0007] From the above summary, it can be seen that high-illuminance and high-color-temperature light has psychological and physiological mechanisms to improve attention, and can have a positive effect and influence on users or objects being irradiated. Therefore, it is necessary to develop a high-color-temperature and high-illuminance lamp to provide a lamp that can reduce eye fatigue and even improve attention and alertness for users.
