Which is brighter, white light or warm light of led lamp? In daily life, we can't live without turning on the light. With the continuous development of technology, there are more and more styles of lamps, and the quality of decoration is also inseparable from the illumination of lights. Which of the following led lights is brighter, white or warm?
Which is brighter, white light or warm light? 1The brightness of white light bulb of LED lamp is greater than that of warm light bulb.
Positive white light and warm white light depend on the use environment. Positive white light is mainly lighting, with high brightness and good lighting effect. If you don't want the light to be too dazzling at night, it is recommended to use warm-colored lights. The led ceiling lamp in the living room is equipped with warm light and positive white light. Therefore, in order not to hurt eyes, it is recommended to install warm white light and positive white light or cold white light.
What's the difference between warm white light and positive white light?
White light is generally at 4000K color temperature, which is cold, while warm white light is at 3000K color temperature, which is yellow. It is generally good to use positive white light in the living room. Warm white light is more suitable for living room. Warm white is close to the color temperature of the bulb, and the color temperature of the white fluorescent lamp is above it.
1, the color temperature is different, warm white looks yellow, anchor looks at skin color, and skin color is white with warm light.
2.LED lighting is generally divided into cold white light and warm white light. The color temperature of cold white light is 4000 K-8000 K, and the higher the color temperature. The whiter the light color is, the ordinary fluorescent lamp is cold white with a color temperature of about 5500K, and the color temperature of warm white is 2500 K-4500 K The lower the color temperature, the yellower the light color is. For example, household incandescent bulbs are warm white light with a color temperature of about 3000K K K. Color temperature and brightness: under the irradiation of high color temperature light sources, if the brightness is not high, it will give people a cold atmosphere; Under the irradiation of low color temperature light source, too high brightness will give people a sultry feeling.
Is the LED light yellow or white?
It is recommended to choose warm white light, which is soft and suitable for reading. Color temperature of LED light source: People use the temperature of complete radiator equal to or close to the color temperature of light source to describe the color table of light source (the color seen when human eyes directly observe the light source), also known as the color temperature of light source. Color temperature is expressed by temperature K. Different color temperatures will make people have different emotional reactions. Generally, the color temperatures of light sources are divided into three categories:
1, warm light
The color temperature of warm light is below 3300K K K. Warm light is similar to incandescent lamp, with more red components, giving people a warm, healthy and comfortable feeling. Suitable for families, houses, dormitories, hospitals, hotels and other places, or places with relatively low temperature.
2. Warm white light
Also called intermediate color, its color temperature is between 3300 K and 5300 K. Warm white light and soft light make people feel happy, comfortable and serene. Suitable for shops, hospitals, restaurants, restaurants, waiting rooms and other places.
3. Cold light
Also known as daylight color, its color temperature is above 5300K, and the light source is close to natural light, which makes people concentrate. Suitable for rooms, conference rooms, classrooms, studios, design rooms, library reading rooms, exhibition windows and other places.
Which is brighter, white light or warm light? 2. What light source is good for the living room chandelier?
1, when choosing, you can decide the choice of ceiling lamp according to the area and height of the living room, and make different choices at different heights. If the area is only a dozen square meters, then * choose the ceiling lamp. If the living room is tall and big, it can be selected according to the owner's hobbies, age, culture, views and standards on comfort and warmth, and requirements for lighting style.
We should consider psychological factors when choosing lamps. You can choose these kinds. We can choose to put yellow crystal lights on the financial position at home, which can be beneficial to the wealth of residents, especially the development of partial wealth. Topaz has the function of getting rich and favoring wealth. If you add the brightness of light, it will play more fully. Of course, you can also choose round or square lighting, which can be beneficial to the overall fortune development of residents. On the contrary, weird lighting will lead to unfavorable feng shui and easily cause anxiety.
2. Is the living room chandelier white or warm?
1, warm light will bring people a warm and romantic feeling, while white light is brighter and clearer. Warm light will create a better atmosphere than white light.
2. The yellow light emitted by the warm light lamp will do some harm to people's eyes no matter day or night. The living room will be brighter than the bedroom and kitchen, so the white light is just right.
There will be many styles of decoration now: simple European, American and Japanese, and the atmosphere created is different. If you prefer warmth, you can choose warm light. If you prefer brightness and practicality, you can choose white light.
3. What should I do if there is a problem with the dimming of the living room chandelier?
1, color repair
We can decorate the whole atmosphere with the color of the living room. For example, the large-scale use of white and light-colored latex paints not only satisfies visually, but also increases the diffuse reflection of light in the living room and increases the number of physical light reflections.
2, increase the light source
In addition to the main chandelier in the living room, floor lamps, desk lamps, wall lamps, small downlights in sky paintings and small spotlights with background decorations in corners and shadows can be appropriately added, so that the light source can create an intriguing layering in three-dimensional space, which can play a very good role.
3. Clever use of mirrors
Mirrors can be used in restaurants, corridors, living rooms and places. The mirror is not a pure rectangle, it can be decorated and beautified. That is to say, under the treatment of the car side, small mirrors are combined into a big mirror, which not only gets rid of the factors of direct people in Feng Shui, but also is a landscape and of course can reflect light.
Which is brighter, white light or warm light? 3 What are the led parameters?
1, color temperature: conventional color temperature: warm white light (WW) 2700-3200k, natural light (NW) 4000-4500k, positive white light (PW) 6000-6500k, cold white light (CW) 7000-7500k, in addition to red and green colors.
2. Power: The general power of LED bulb lamps is below 12W. Common LED bulb lamp power is divided into: 3w, 4w, 5w, 6w, 7w, 8w, 9w,10W..
3. Voltage and current: Voltage and current are also very important basic parameters of LED bulb lamps. The grid voltage in different countries in the world is different from that used in some occasions. Commonly used voltages are 12v, 1 10v, 220v and 85v-265v.
4. Current is divided into input current and lamp current. First: input current: it can pass the power supply test. Different forces are different, depending on the instrument. Second, the lamp current: the general high power is 300Ma-320Ma-. Current has a great influence on the light attenuation of LED lamps, so the stability of current is also very important. The current and voltage of the lamp bead should not be too large, otherwise it will seriously affect the life of the LED lamp.
5. Light efficiency: Light efficiency is also an important factor of LED bulb lights. At present (2065438+August 2003), the luminous efficacy of lamp beads using chips such as Riya and Ke Rui is generally around150-0lm/w. At present, the luminous efficacy of lamp beads using chips in Taiwan Province Province in China is basically around100-130lm/w.
What are the advantages of LED lights?
1, the luminous rate of led lamp is very high, which can reach 80 1m/w, which plays an important role in energy saving.
2. There are many kinds of color temperatures of 2.led lamps, which can be selected according to your own needs. All kinds of color temperatures have good color rendering and high color rendering index.
3. The use of led lamps can reduce the damage to the line and will not pollute the power grid, because its EMI meets the global indicators, the power factor is greater than or equal to 0.9, and the second harmonic distortion is less than or equal to 20%, which can reduce the power loss of the power supply circuit.
What are the led lamp parameters? What are the advantages of LED lights? As can be seen from the article, in fact, led has various parameters. Led has not only power parameters, but also color temperature parameters. Of course, different LEDs have different internal voltages and currents. Generally speaking, LED has many color temperatures and is a durable product, which is worth buying by consumers.
