Nowadays, words such as "human-centered lighting", "day and night lighting" and "biological lighting" are often found in the newspapers. In fact, no matter what the word is, it is nothing more than saying that properly dimmed lighting can create ideal conditions for human beings within 24 hours.

Moreover, no light source can be as "adjustable" as an LED, and the light source can be provided at a specific color temperature, spectral power, color and brightness. In short, human-centered lighting can stimulate people's excitement in the morning and afternoon, and can relax them at night. It can be tuned to the same level as the sun, thus reinforcing the rhythm of sunrise and sunset over millions of years and the 24-hour circadian rhythm.

If designers can incorporate as much natural lighting as possible into the palette of LED colors, it will have a huge impact. We all know that stimulation and alertness can improve learning and efficiency, and relaxation can help sleep. On the contrary, the wrong light at the wrong time can ruin these things, and some researchers believe it can help produce cancer, diabetes and other diseases.

Dimmable, human-centered lighting (HCL) can be applied anywhere, such as schools, offices, hospitals, homes, etc.

Human-centered lighting (HCL) can achieve results in hospitals. Tune the LEDs to stimulate blue frequencies at certain times of the day, and warm light tones at other times to help the patient sleep and heal. In an office, a well-designed lighting system can boost morale and productivity.

In summary, after adding HCL gas to the LED lighting, the emitted light is beneficial to the human body.

When the factory produces this kind of LED lighting with HCL gas, it may leak HCL gas into the workshop during the production process, thereby affecting the health of the staff. The effects of HCL concentration on the human body are as follows:

The state stipulates that the allowable concentration of occupational zui is 5ppm.

For the safety of the staff, the HCL sensor must be added in the workshop to monitor in real time. If there is a leak of HCL gas, the sensor will alarm to ensure the safety of the staff.
