Support a relaxing environment before bed with the idea of "bringing sunlight back home"

Premium lighting brand "lipro" is launching a rechargeable sleep light equipped with next-generation LEDs that utilize its unique sunlight reproduction technology in the Japanese market. (Sunlight reproduction technology: Powered by SunLike) This product transcends the traditional boundaries of lighting that simply pursues "brightness," taking on the role of "health infrastructure" that supports the mind and body of modern people. Focusing particularly on the quality of "sleep," which is the foundation of health, and amidst the widespread habit of looking at smartphones before bed, this product offers a nighttime environment that is gentle on the eyes by adjusting the bedside lighting. Soft light that suppresses the stimulation of strong light creates a calming atmosphere before bed, supporting an environment conducive to falling asleep in a relaxed state.

Social Issue: Decline in Sleep Quality Affecting Modern People

In modern society, with the spread of smartphones and the normalization of night-owl lifestyles, many people are exposed to inappropriate lighting environments before bed. In particular, the strong blue light emitted by general LED lighting and digital devices is considered a major factor in suppressing the secretion of melatonin, the sleep hormone, leading to difficulty falling asleep and disruption of sleep cycles.

Decline in sleep quality affecting modern people

According to a survey by the Ministry of Health, Labour and Welfare, approximately one in five Japanese people suffer from some kind of sleep problem. This is a serious social issue that leads to reduced concentration during the day, fatigue, and even an increased risk of lifestyle diseases. High-quality sleep is essential for maintaining a healthy mind and body, and for that, a review of the lighting environment before bed is urgently needed.

Issue Impact of General Lighting/Devices Solution Provided by lipro
Difficulty falling asleep Suppression of melatonin secretion due to blue light exposure before bed Promotes relaxation with 3000K warm white light that suppresses blue light
Decline in sleep quality Disruption of body clock by unnatural light, hindering deep sleep Supports natural biological rhythm by reproducing sunlight spectrum
Eye strain Eye fatigue due to strong light or flicker at night Reduces strain with flicker-free design and eye-friendly light

"Sleep-friendly light" designed to reproduce the wavelength of sunlight

The lipro Sunlight Sleep Light provides "healthy light" through next-generation LEDs with unique sunlight reproduction technology.

Whereas conventional LEDs create artificial white light based on blue LEDs, lipro reproduces the wavelength distribution (spectrum) of sunlight to the utmost extent. In particular, this product is specialized for use before bed and has the following technical features. (Sunlight reproduction technology: Powered by SunLike)

Optimal 3000K warm white light before bed

Specialized in warm and calming 3000K warm white light that does not hinder melatonin secretion. It recreates the natural light environment after the sun sets, guiding the mind and body into a relaxed mode.

Fundamental blue light control

It eliminates the sharp blue light peaks known to be harmful to the retina, achieving a gentle, flat light. It has obtained "RG0 (Risk Group Zero)" certification, an international photobiological safety standard.

Completely flicker-free design

Thoroughly eliminates invisible light flicker. Minimizes stress on the brain and eyes even during long periods of reading or precise work.

Improving Sleep Quality Through Light

A lighting environment utilizing unique sunlight reproduction technology is not merely "comfortable"; research has shown its physiological benefits.

"Studies suggest that during sleep after spending time in a lighting environment using SunLike, delta wave activity, indicative of deep sleep, is higher compared to conventional LEDs, which helps induce deeper sleep. This is expected to improve sleep quality and positively impact alertness and concentration the following day." (Based on research results by Seoul Semiconductor and university research institutions)

Reference: SunLike Research Overview (LED Journal)

Users who have actually used the product have reported comments such as "I fall asleep more easily," "I wake up less often in the middle of the night," and "I feel refreshed when I wake up in the morning," demonstrating that the quality of light directly impacts the quality of sleep, and consequently, the quality of life (QOL).

Comments from the person in charge

Lighting as a "source of health"

"We believe that light is not just 'brightness,' but a crucial element affecting human health, just like food and sleep. Especially regarding the sleep issues faced by many modern people, approaching it through light quality is an 'infrastructure' for living a healthy life. We are confident that through this sleep light, we can help people in Japan regain high-quality sleep and contribute to their fulfilling daily lives, both mentally and physically."
