Why Is Lighting Quality Important?

Good lighting reduces the risk of health problems, increases safety, and enhances productivity. For this reason, we place great importance on the light quality of our illuminated magnifiers. They are not just magnifiers with light, but powerful illuminates with excellent light output.

How To Judge The Quality Of Lamps?

We show the quality of our products from the following seven main aspects.

1. Correlated Color Temperature (CCT)( K)

CCT is Correlated Color Temperature, In the normal range of 2700K – 6500K, warm white is 2700K – 3000K, and over 5000k is Cool white.

2. Illuminance(Lux)

What kind of lighting not only protects eyesight? But also makes people feel clear and happy?

Currently, there is no standard scale, and one reason is that everyone’s eyes adapt to different ranges.

Secondly, there are many factors related to illumination. Such as object image, environment, nature of light, age, congenital visual acuity, etc.

What kind of illumination is enough? How do mate different illuminances in different indoor situations?

The illumination is 0.0001-1 lux, low light, dim light. It will cure the toss and discomfort. Help your sleep quality and fast falling asleep.

The illumination is 10-30 lux, which is conducive to protecting the baby’s cornea and creating the most suitable light environment for the baby.

The illumination is 40-80 lux, which is conducive to creating the best viewing atmosphere and protecting the eyes under the experience of relaxing the body and mind.

The illumination is 90-150 lux, which is suitable for the dining mode of the restaurant so that the food has “color, flavor” and creates a warm family atmosphere.

The illumination is 200-400 lux, creating the best atmosphere for focused thinking, which can calm people down and prevent eye fatigue at the same time.

The illumination is 500-600 lux. It is suitable for study and office building, creating a focused learning atmosphere for children. The most important thing is to protect the eyes from long-term close use and alleviate eye fatigue in lighting.

So What Does Illumination Have To Do With It?

Illumination Is Related To Vision

Sunlight and naked light will produce an uncomfortable glare. 

Glare hurts vision, causing reduced visual function, eye fatigue, eye tingling, and even headache in severe cases. 

Therefore, Please prevent the children reveal to inappropriate light brightness, and children should not be allowed to look directly at the sun and naked lights.

Too much light can damage your eyesight, and insufficient light is also harmful to your vision. 

When the light is sufficient, it cannot fully stimulate the excitability of retinal cells.

The scenery seen by the eyes cannot reach the brain and cannot be exciting. The visual process presents a slow state, vision loss, visual fatigue, and the activity of the entire central nervous system and inhibits the body.

We all have the experience of feeling lethargic when the weather is gloomy. On the other hand, when the sky is clear, you feel energized and out of the ordinary good mood. When it rains continuously, what people want to do most is to sleep to reduce the feeling of visual fatigue.

Effect Of Illumination On The Surrounding Environment

The light environment can directly affect the atmosphere of space and affect people’s feelings. Affect people’s emotions, creativity, and even the quality of life and production efficiency. 

If the light environment doesn’t matter, we can return to a previous life. Hang a light bulb in the middle of the room and cut a cardboard cover. Why talk about space quality.

The effect of illumination on the surrounding environment is clear as daylight.

We all know that the same lit candle can only fluoresce in the open place but can almost illuminate the whole room indoors. 

In the same room, different colors of walls have various illumination.

The white walls have a strong reflection coefficient, and the illumination is increased, making the room very bright, while the dark walls make the room darker. 

A strong reflection coefficient can cause reflective glare. 

To avoid reflections on the walls, the wall 1.5m above the ground can be painted yellow or other light colors to turn the reflected light parallel to the eyes into diffuse reflection.

It seems that wall painting is not only to protect the wall but also to protect eyesight. There are two functions of table lamp shade: one is to reduce the glare of light; Second, to increase the illumination per unit area.

3. Color Rendering Index( Ra )

Color rendering index is also a vital professional term in the lighting industry. From the following article, you can answer the definition of the color rendering index in detail.

4. Light Source Efficiency( lm/w )

Light source plays a significant role in the revival of lamps. If you want to have a deeper understanding of the light effect, you can see the detailed explanation in the following article.

5. Power Factor Of Power Supply

The power factor is a factor to measure the efficiency of electrical equipment. The utility model increases the reactive power of the power supply circuit and reduces the alternating power factor of the power supply circuit. In an AC circuit, the phase difference between voltage and current( Φ) 

The cosine of is known as the power factor, using the symbol cos Φ 

In numerical terms, the power factor is the ratio of active power to apparent power, i.e. cos Φ= P/S

6. Heat Dissipation Effect

The heat dissipation structure and led lamp materials directly affect the heat dissipation effect.

The heat dissipation effect of LED lamps is poor, the light attenuation of lamp beads is strong, and the service life of lamps is short.

7. Luminous Flux(lm)

Luminous flux refers to the radiant power that the human eye can perceive.

It is equal to the product of the radiant energy of a few bands and the relative visual rate of that band in unit time. 

Because the relative visibility of human eyes to the light of different wavelengths is different, when the radiation power of the light of different wavelengths is equal, the light flux is not equal. Luminous flux refers to the derived amount of radiation flux evaluated according to the international standards for human visual characteristics, expressed in symbols Φ (or Φ r) Indicates. The relationship between luminous flux and radiation flux is

The apparent efficiency is the maximum value of light in the formula, 

68kW / LM; V ( λ) Is the standard spectral luminous efficiency function specified by the International Commission on illumination (CIE); Φ e λ Is the spectral density of radiation flux. 

The unit of luminous flux is LM (lumen); λ Is the spectral luminous efficiency.

From the above aspects, let you buy high-quality lamps. 

High-quality lamps can prolong the lamp’s service life, improve efficiency, and reduce maintenance and replacement costs, to save energy and money. It also indirectly protects our environment and reduces the necessary waste pollution.
