★ . Experts suggest that when indoor lighting must be used, the five principles of lighting should be grasped:
1, using a wide range of lighting, the light should shine on the entire desktop;
2, using uniform lighting, the illumination of each part must be consistent;
3, to maintain a stable lighting, the light source should not be bright or flashing when it is dark;
4. Maintain adequate lighting;
5. Finally, be careful not to let the light shine directly into your eyes.
★ There should be common sense of healthy lighting when using lamps: for example, the best illumination for reading has a great relationship with age, and the illumination required by the elderly is 15 times that of children.
★ Why does the high frequency eye protection lamp have electromagnetic radiation:
In order to overcome the stroboscopic frequency of the 50hz fluorescent lamp, the high-frequency eye-protection lamp will inevitably bring electromagnetic radiation of the high-frequency power source by using a frequency of 40,000 to 55,000 hz. Environmental experts point out that excessive electromagnetic radiation may cause palpitations, insomnia, leukopenia, memory loss, and even reduce immune function, damage to the blood system and nervous system.
Electromagnetic radiation damage is cumulative, the closer the distance, the lighter the weight, the greater the damage. It is a consensus to have one more protection and one less risk.
★Led is a kind of semiconductor solid-state light-emitting device: it has the advantages of small volume, light weight, high brightness, low energy consumption, long life, high safety, high color purity, good directionality, low maintenance cost, environmental protection and no pollution.
★Led lighting is a kind of green light source: low working voltage, low power consumption; stable performance, long life (generally 100,000 hours); strong impact resistance and vibration resistance; LED lighting products can provide high quality light environment and enhance The light effect of the illumination system, no infrared and ultraviolet components, high color rendering and strong directionality of light; good dimming performance, no visual error when the color temperature changes; cold light source has low heat and can be safely touched; Improve glare, reduce and eliminate light pollution. Zero strobe will not cause fatigue in the eyes. No electromagnetic radiation, to prevent radiation pollution to protect the brain. It not only provides comfortable lighting space, but also satisfies people's physiological health needs. It is an environmentally friendly and healthy light source. Long-term use can protect vision and prevent myopia.
