Natural Light Illuminates a Beautiful Life

Light is the warmth of a home and the foundation of happiness. lipro upholds the philosophy of "delivering healthy lighting environments to more homes with natural light and innovative technology," meticulously crafting each reliable lighting product with uncompromising craftsmanship. lipro is confident that exceptional quality is not only a promise to its products but also a tribute to a beautiful life.

Light Stabilization Technology That Transcends the Test of Time

For long-term use, lipro has achieved a replacement cycle of over 10 years under normal use through repeated testing and optimization. We strictly control everything from material selection to design and manufacturing processes, fundamentally eliminating the possibility of initial defects. We strive to ensure that every light maintains stable performance over time, continuously providing comfortable light, and becoming a reliable companion in users' lives.

Durability as an Instinct in Design

Temperature Control and Heat Dissipation Design

温度制御

Our patented temperature control technology optimizes the heat dissipation path of LED chips, reducing core temperature by 30% and significantly extending the lifespan of the LED chips.

Optimized Side-Emitting Layout Design

側面発光設計

The side-emitting design, combined with uniform diffusion from the light guide plate, prevents localized overheating and enhances the softness of the light.

Materials: Precision at a Molecular Level

材料品質1 材料品質2

Our ceiling lights are manufactured from high-quality flame-retardant eco-materials, complying with EU REACH and RoHS regulations. They offer excellent safety and durability, and are recyclable.

Testing: Exceeding Industry Standards to Withstand the Test of Time

Double 85 Test

ダブル85テスト

Continuous powered operation for 168 hours (7 days) at 85℃ and 85% humidity. This simulates durability under extreme climatic conditions.

High/Low Temperature Cycle Test

高低温テスト

Verifies material fatigue resistance under rapid temperature changes from -40℃ to 60℃.

Continuous Lighting Test

連続点灯テスト

A 10,000-hour continuous lighting experiment confirms that the lumen depreciation rate is below industry standards.

Ultimate Optical Performance Verification: Rigorous Testing and High-Precision Optical Standards

To ensure the excellent quality and comfort of our lighting products, we combine laboratory-level optical testing systems with international certification standards to comprehensively verify luminous flux, light distribution performance, flicker stability, and color consistency.

Luminous Flux Measurement Test with Integrating Sphere

積分球テスト

The ceiling light is placed at the center of an integrating sphere to precisely measure its luminous flux, spatial distribution characteristics, and material reflection/transmission properties.

Light Distribution Test

配光テスト

Fixed on a goniophotometer turntable, a detector records light intensity at various angles. This comprehensively evaluates light directionality, uniformity, and coverage.

Flicker Test

フリッカーテスト

Detailed detection of temporal variations in light source brightness and spectrum to prevent eye strain caused by flicker. Achieves IEEE PAR1789 certification.

Ultimate Color Reproduction Test (Color Deviation)

色彩テスト

Strictly controlled color deviation to SDCM ≤ 2.4 (superior to the industry standard of 3 steps). Prevents color cast and perfectly reproduces true light colors.

Ensuring a Safe and Comfortable Lighting Environment

As lighting products are frequently used in daily life, safety and comfort are paramount. lipro ensures long-term reliability through rigorous design verification and high-standard testing, providing a safe and comfortable lighting environment.

Seismic Drop Test

耐震テスト

Using the Great Hanshin Earthquake (seismic intensity 6) as a safety standard, a 3-hour high-intensity vibration test was conducted. Achieved zero detachment, damage, or malfunction.

Glow-Wire Test (Fire Prevention)

防火テスト

Strictly passed the IEC 60695 Glow-Wire Test (850℃). Confirmed that flames self-extinguish within 30 seconds and no dripping material ignites washi paper.

Noise Test

騒音テスト

Achieved operating noise below 22dB in a professional testing environment. Quieter than a library environment, completely eliminating current noise and mechanical vibrations.

EMC (Electromagnetic Compatibility) Test

EMCテスト

Obtained national-level EMC certification. Fully meets electromagnetic compatibility requirements and effectively suppresses its own electromagnetic interference.

Respecting All Life Scenes with Comfortable Light

lipro takes actual life scenes as the starting point of its design, meticulously considering every detail of light. From the appropriate brightness upon waking in the morning to gentle light late at night, lipro creates light that understands life.

生活シーン1

Achieve a wonderful, uncompromising life, starting with light.

生活シーン2

For environments requiring high-precision color reproduction, deliver true colors.

生活シーン3

Seamless Scene Transitions with Up/Down Linked Supplementary Lighting

生活シーン4

A Gentle Moment That Protects Your Eyes

What is often considered "good light" is not just light that passes equipment verification, but also light that can withstand the test of life.

Defining Quality Living with Ultimate Optical Technology

lipro's eye-friendly ceiling lights, with "natural light technology" at their core, undergo testing that exceeds industry standards in every process, from durability and safety to light quality. The choice of 100,000 households worldwide is a clear testament to our philosophy of "protecting happiness with light."
