I. What is a ceiling lamp?

The ceiling lamp is a light source installed in the house close to the roof. The overall appearance is relatively simple and suitable for use as overall lighting. The function and characteristics of the ceiling light are basically the same as those of the chandelier, but the form is different. Chandeliers are mostly used in higher spaces, while ceiling lamps are used in lower spaces.

II. The material of the ceiling lamp

Like other lamps, there are many materials for making ceiling lights, including acrylic, glass, metal, crystal, etc. Among them, crystal and glass have a longer life, are not easy to age, and are more fashionable. The metal parts on the lamp, such as the chassis, screws, etc., will slowly oxidize, and the use time is generally about 5 years.
It is recommended to choose aluminum for the ceiling light body, which is lightweight, can reduce the risk of accidental fall off, and has a better anti-corrosion and anti-rust texture; the lamp shade can be made of acrylic material, which has better light transmittance and more uniform light output than glass masks.

III. What are the advantages of LED ceiling lights?

1. High luminous efficiency

The luminous efficiency of LED itself has reached more than 130lm/W, so the overall luminous efficiency of LED ceiling lights can reach 100lm/W. And this efficiency is still increasing every year. It is estimated that by 2020, the luminous efficiency of LED itself will reach 240lm/W. High light efficiency means energy saving. According to the measured results, an 8W LED can replace a 32W ceiling light. Electric power can be saved more than 4 times.

2. Long life

The life of LEDs is 100,000 hours. After the LED ceiling lamp is made, it is actually recognized that the life is at least 30,000 hours, and the high-quality can achieve 50,000 hours, which is more than 10 times longer than that of fluorescent lamps. The life of fluorescent lamps is 10,000 hours, which is also more than 5 times longer.

3. Does not contain mercury and other toxic substances

When everyone pays attention to the advantages of high luminous efficiency and energy saving of LED light sources, a very important advantage of LED lighting is that it is mercury-free, but it is often ignored. We know that mercury is an extremely toxic substance, but almost most of the high-efficiency electric light sources used before 2012 contain mercury, whether it is common fluorescent lamps, compact energy-saving lamps, or high-pressure mercury, metal halide Lamps etc. contain mercury.
Mercury has a very low boiling point and can evaporate at room temperature. After an old discarded light source is broken, it immediately emits mercury vapor to the surroundings, which can instantly make the mercury concentration in the surrounding air reach 10-20 mg/m³, which exceeds the maximum allowable concentration of mercury in the air of 0.01 mg/m³ 1000 to 2000 times.
Therefore, the persistence, easy migration and high bioaccumulation make mercury one of the most concerned environmental pollutants in the world. The worst mercury poisoning incident in history was the Minamata disease incident in Japan, when hundreds of people died when the water in Minamata Bay was contaminated with mercury. Since 2013, the Japanese government has learned a lesson and requires that all discarded fluorescent lamps must be treated with toxic substances, thus requiring people who buy ordinary fluorescent lamps to pay double the price to pay for the treatment of toxic substances in advance.

4. No ultraviolet radiation, no light pollution

LED ceiling lights can provide light with various color temperatures as needed, usually 2550-3700K, and 4700-7000K. The LED ceiling light has no glass parts, is resistant to shock and vibration, and is easy to transport. LED ceiling light does not need aluminum radiator, low cost and light weight. The LED ceiling lamp has high safety, no harm to the human body, and saves energy and reduces consumption.

III. What are the advantages of LED ceiling lights?

1. Scope of application

LED ceiling lights are suitable for long-term lighting in shopping malls, banks, hospitals, hotels, restaurants and other public places.
LED ceiling lamps are suitable for indoor and outdoor use, and can also play a decorative function.
LED ceiling lamps have the functions of fire prevention and air purification in terms of performance.

2. Product Features

The cover of the LED ceiling lamp is made of acrylic material, with uniform light color, anti-glare and high light transmittance.
The LED ceiling light has a built-in power supply for easy installation.
LED ceiling lamps can replace traditional ceiling lamps.
The LED ceiling lamp can choose wireless remote control dimming, light control switch, voice control switch, human body induction switch and other functions. The lamp is suitable for corridors, aisles, toilets, corridors, guest rooms, aisles, toilets and other places.

V. How to choose ceiling lamps?

1. Determine the purchase quantity

The places where ceiling lamps are needed in a house are living room, dining room, balcony, bedroom, study, etc. Before purchasing a ceiling lamp, it is necessary to count the quantity to be purchased. The bedroom can choose the same series of products, the living room and dining room can choose the same style of ceiling lamps with different shapes, and the balcony is best to choose the ceiling lamps with higher waterproof index.

2. Choose a look

Ceiling lamps are available in round and square shapes. Generally, it is more suitable to choose round ceiling lamps in living rooms such as bedrooms and study rooms, while the choice of square ceiling lamps in living rooms and dining rooms makes the space more spacious. Starting from the decoration style, it is more versatile to choose a ceiling lamp with a simple shape, which is attractive and does not choose the decoration style. While the shape is simple, if the design is a little different, it will give people a sense of low-key and design.

3. Select the mask material

The mask of the ceiling light is something we can actually touch. There are many ceiling lamps manufacturers on the market now, and they use different mask materials. The most common ones are acrylic masks and glass masks. The most commonly used are acrylic face masks. To test the quality of the mask, you can first press the mask with your hand to see how soft it is, and the softer one is better; then put your hand over it, see the color, and check the light transmission effect of the mask; finally, open the cover to see if it is easy to disassemble.
It is best to choose a fully enclosed lampshade. Mosquitoes can’t get in, so there will be no small black spots when the lamp is turned on. There is no need to keep cleaning it, and it will be more convenient to clean.

4. Select the light source

According to the different light sources used, ceiling lamps can be divided into ordinary energy-saving light bulbs and LED light sources. Ceiling lamps with different light sources are suitable for different places. For home use, LED is a good choice. The LED light source ceiling lamp is not very expensive, but it is very power-saving, has a long service life, and is also very bright, and the cost performance is very high. But pay attention to choose a flicker-free LED light source, which is more conducive to protecting eye health.

5. Color temperature and wattage selection

Regarding the color temperature, generally choose 3000K or 4000K. The color of 3000K is yellowish, which is warm light, suitable for dining rooms and bedrooms; the color of 4000K is white, which is neutral light, suitable for living rooms and kitchens. Of course, if economic conditions permit, three color lights is a better choice. You can choose different color temperatures according to your own needs, which can meet the different needs of your home.
Regarding the wattage, it is not that the bigger the wattage, the better. It is also very important to choose the appropriate wattage. The lighting in the bedroom does not need to be too bright, so it is enough to calculate the brightness of 3 watts per square meter. Generally, the brightness of 30-45 watts is enough for a bedroom of 10-15 square meters; and the living room needs to be brighter, so according to 5 watts per square meter for the calculation of brightness, for example, a 30-square-meter living room chooses a brightness of about 150 watts.

6. Choose the size of the ceiling light

The size of the ceiling lamp depends on the lighting area. Be careful not to use a ceiling light that is too small, it will make the ceiling look empty, and do not use a ceiling light that is too large, it will make the room look depressing. Generally speaking, for bedrooms with an area of less than 10 square meters, choose a ceiling lamp with a diameter of less than 45cm; for a bedroom with a size of 10-20 square meters, choose a ceiling lamp with a diameter of about 60cm; for a bedroom with a size of 20-30 square meters, this square meter should choose a ceiling lamp with a diameter of about 60cm. The diameter of the ceiling light is about 80cm.

Frequently Asked Questions about Ceiling Lights

Q: Can ceiling lights be installed in any space?
A: As long as there are lighting circuits on the ceiling or the wall itself, it can basically be installed. Just be aware that different brands of products have different installation methods. For example, Japanese brands usually need to install the hanger first; international version products may be attached with quick connectors, which can be directly connected to the wall wire, and then use other tools. Then use other tools to drill the wall and fix it. Therefore, it is recommended to confirm the connector format of the lamp before purchasing, and it is better to choose the style that is convenient for you to install.
Q: Can the ceiling light replace the bulb by itself?
A: Not necessarily. Since most ceiling lamps use LED lamp beads/strips and are welded together with the lamp holder, once the LED lamp fails or its life is exhausted, the whole set needs to be replaced. However, there are also some brands on the market that offer replaceable styles, or provide dedicated maintenance, warranty and other services, which can effectively extend the service life of the ceiling lamp.
Q: Do ceiling lights really save electricity?
A: The LED bulbs used in the ceiling light not only have lower wattage than traditional or energy-saving bulbs, but also have the characteristics of high luminous efficiency, so it is indeed more power-saving after long-term use. However, the amount of power consumption still depends on the wattage (W), so if you want to achieve the best power saving effect, don't forget to pay more attention and compare the specifications of each product.
