Home lighting small science | How to choose the color temperature and brightness of the light?

CCT Tuneable Panel Light at home are not only used for lighting, but also for decoration and adjustment of the atmosphere. Whether it is decoration or refurbishment, the choice and application of home lighting is very critical.

Light brightness and color temperature are also two crucial factors. Let’s learn from you today about the color temperature and brightness of home lighting.

What is color temperature
Color temperature is a physical quantity used to define the color of a light source in illumination optics. That is, when a black body is heated to a temperature, and the color of the light emitted by it is the same as the color of the light emitted by a light source, the heating temperature of this black body is called the color temperature of the light source, or color temperature for short. The unit is represented by “K” (Kelvin). 1 color temperature is 1K.

Use of color temperature
In indoor lighting, the most intuitive feeling that the change of color temperature brings to us is the change of light from warm to cold. The lower the color temperature value, the warmer the light color; the higher the color temperature value, the colder the light color.

Warm light
The color temperature is 3300K and below, the effect of warm color light is similar to that of incandescent lamp, and the red light component is more, giving people a warm, warm, healthy and comfortable feeling. It is often used in places such as homes, dormitories, hotels, or places with low temperature.

Cool white light
The color temperature is between 3300K-5300K, also called neutral color, the light is relatively soft, making people happy, relaxed and comfortable. Suitable for public places such as shops, hospitals, restaurants, restaurants, offices, etc.

Cool light
The color temperature is 5300K and above, also called daylight color, the light source is close to natural light, it has a bright feeling, and it is easy to concentrate. It is suitable by CCT Tuneable Panel Light in for offices, meeting rooms, classrooms, design rooms, reading rooms, warehouses and other places.

Even in different areas under the same place, different color temperatures will be used to achieve different lighting effects. Take the supermarket as an example. The color temperature of the supermarket’s fresh meat area, baking area, vegetable and fruit area, and seafood area are all exquisite. The difference in color temperature will be used to highlight the color of the corresponding ingredients and make them look more fresh and attractive.
This is why the fruits that are often bought in the supermarket are not so delicious when taken away in ordinary environments.

Home lighting color temperature selection
At home, the color temperature is the same, especially in restaurants, entrances, living rooms, decorative walls and other places, affecting the atmosphere and decorative effects of the home, which has a great impact on our mood and life experience.

Generally speaking, the color temperature of ordinary household lighting is in the range of 2700K-4000K.

I would like to recommend the color temperature selection for each area of ​​the family.

living room
First of all, the living room will be the main space for external communication in your home, and it is the anchoring place to show the main temperament. It is necessary to create a bright and relaxing lighting effect, especially for the living room with high ceilings. Choose the color temperature of 3500K-4000K for the main lamp. The most suitable.

Sometimes, the living room is a place where a family can sit quietly after a meal and enjoy a nap. Instead, a more warm and comfortable home atmosphere is needed. It is recommended to choose 3000K for ambient lights other than the main lights, such as the surrounding downlights and light strips 3000K-3500K.

bedroom
The bedroom is a place to rest. Naturally, the light should not be too bright. It needs to create a relaxing atmosphere and help sleep. The color temperature is also the most suitable for the warmer 2700K-3000K.

study
Most families with children will build a study room or an area for children to study quietly. The lighting atmosphere should help focus on thinking and provide enough brightness.

If you focus on reading, it is recommended to use 3500K-4000K color temperature CCT Tuneable Panel Light to help boost your spirits.

If you use a computer as the mainstay, since the computer color temperature is mostly 5500K-6000K, the original light is too white, you can consider using a lower 3000K-3500K color temperature to balance.

Bathroom & Kitchen
Generally speaking, these two areas do not need to pay attention to the atmosphere, they need to be bright and clear. 4000K is recommended to make the space look more open.

restaurant
The effect of restaurant lighting affects food color and appetite. But unlike the public restaurant outside, there is no need for an overly bright and lively atmosphere. Instead, it is recommended to use the warmer 3000K-3500K warm white light to gather the family together to enjoy delicious food.

Entrance
The entrance of many small partners will be used as decoration. The whole room is mainly decorated with softer 3000K light source.

Aisle stairs
After all, the aisle stairs must be moved frequently, especially for corridors with high ceilings. It is recommended to use a slightly brighter 3500K.

cloakroom
The cloakroom involves changing clothes and matching colors. Bright neutral light is the most suitable and will not affect the color judgment. It is recommended to choose 3500K-4000K.

Whole house unified
Some friends who are pursuing minimalist styles try to make the color temperature of the light source at home as uniform as possible to achieve better results. In this case, the safest choice is naturally 3500K or 3000K.

After talking about color temperature, let’s talk about brightness, that is, wattage, which is also a crucial point.

The brightness of the light is determined by the power of the energy-saving lamp. Power is the physical quantity that describes the function of the bulb. It is usually expressed by the work done by the bulb per unit time. The unit is watt, abbreviated as watt, and the symbol is W. 100W means 100 watts. .

Choice of wattage
Luminous efficiency, especially the luminous efficiency of energy-saving lamps will also affect the brightness, but after all, it is recommended that everyone try to buy high-quality brands, there is not much comparison here. In addition, the wattage selection of household lighting mainly considers the lighting area of ​​the house.

How many watts of lights are allocated in how many areas? Take the common LED lights as an example to give you a table. You can roughly calculate the required wattage based on the area of ​​each room in Xiali.

The living room and kitchen are required to be transparent and bright. Remember not to leave dark areas in the kitchen lighting, and try to have sufficient lighting in every corner. Calculate the lamp wattage according to 2.5~3W per square meter per square meter.

The bedroom lighting should be soft, so that people can quickly go to sleep, and the wattage of the bulb should be low. Note that children are very sensitive to light, all light sources should not be direct, spotlight downlights must be avoided, and ceiling lights are best.

The above is just a reference, the specific wattage should be decided according to the actual needs of the home. Because the lighting is not only related to the area, but also related to the decoration style, wall color, and lighting style of your room.

Number of lamps
Let me add the number of lamps by the way. First, determine which style of lamp to choose according to your own style. For example, the retro style will consider the main lamp, while the minimalist style is mostly without the main lamp.

It is also necessary to anticipate the range of illumination required by each lamp, and try to ensure that each area can have light.

Under normal circumstances, the number of lamps = 5W per square meter X total area ÷ single lamp wattage

The above is the basic common sense about home lighting. It is mainly adjusted according to their own preferences and needs.
