The energy-saving lamp has been relegated to the past. Almost all household lights are LEDs.
There are many LED lamps available on the market, and it can be difficult to tell the difference between the good ones and the bad. This article will teach you how to select high-quality LED lights.
LED lamps are made up of three components: the driver, the light source board and the heat sink. Let’s start with the driver. Non-isolated drivers are usually used for household LED lights. This driver is a good choice for its reliability, efficiency and cost. Voltage fluctuations do not affect the lights’ ability to work.
In order to compete on the market today, many companies use linear or resistor-capacitor power supplies in place of non-isolated supplies. Both of these power supplies are not very resistant to impact. It is likely that a nearby storm will cause a surge in voltage. Can only operate at a set voltage.
When purchasing, make sure you check the input voltage range.
Resistance-capacitance and linear voltages are generally writt-en as 220-230v, and non-isolated power supplies are generally writt-en as 175-250v, and some can be 110 -250v voltage fluctuation has no effect on this lamp.
When choosing, be sure to consider the input voltage range.
Let’s now talk about the board that contains the LED light sources. Currently, the majority of LED light sources are welded to the aluminum substrate. The quality of the LED light source is hard to judge with the naked eyes, but it’s not an issue after a few use years. You can check the light that is on the package. It is better to select a color temperature that is below 6000k. Color temperatures of 3000k are preferred by Europeans and Americans. This is a slightly yellowish color, like the sun rising in the morning.
We prefer whiter shades in our country. In general, 6000k looks like the sun at midday. It is brighter, but also whiter. The best choice is to use a light source with a 4000k color temperature, as it is a more moderate option. The light will appear blue if it is above 6000k. Blue light hazards are what we call this, so don’t choose a temperature higher than 6000k.
Let’s finish with the heat sink. A heat sink is necessary because the LED light source produces heat while it works. If the heat isn’t dissipated quickly, the LED will be damaged.
Most bulbs are aluminum heat sinks that have been plastic-coated. They feel plasticky to the touch. There is a layer aluminum in the bulb.
The more power the LED has, the higher the temperature. The heat sink usually has a power limit. So, when purchasing a lamp do not go overboard with power. The A60 is not supposed to exceed 10 watts. It will be discounted if it is over the lifespan.
What to look for when choosing LED lights
Blue light is the most important factor to consider when choosing LED lights.
The blue light can be very harmful to children, especially those under the age of eight. You can learn more about blue light by searching on Baidu.
Since the light from LEDs is a white light that is synthesized by combining three colors, red, yellow, and blue, blue light is unavoidable. A lot of LED research is being done abroad to try and solve the blue light problem. I hope we can all use LEDs without blue light in the future.
Online, it is uploaded that you can judge the LED strobe using your mobile phone. It is not an accurate standard and you need to consider all the aspects of light color when making a judgment.
Energy-saving lamps and LDE lamps
LEDs can be more efficient and save energy compared to energy-saving bulbs. The phosphors of energy-saving bulbs need to be fully preheated, especially when it is cold outside, before they reach the brightness required for the logo. LEDs aren’t required.
For children’s bedrooms, it is recommended to use neutral lighting with a 4000K color temperature.
You can choose between neutral light, white or yellow light for the living room.
In the living room, ceiling fan lights should not be used. The light intensity of the ceiling fan lights is insufficient for use in the living room.
In terms of household LED lighting, yellow light has less impact on the eyes. White light has more effect, while blue light only affects children younger than 8 years.
When choosing the right lighting fixture, you should consider:
- The LED light will appear blueish if there is too much light. This is bad. White light is normal.
American-style lamp shades are thicker, so white light bulbs should be used.
- The right size
- Style should be in harmony with the decor of the house.
The finishing touch is the lamp. Not only must we choose the style but also the color of the light. For simple Nordic style, choose simpler lamps. European and American chandeliers will work best.
- When choosing, pay attention to the light color and quality.
Make the issue of lamp height more popular:
Customers have said that the new Chinese and American style lamps are so thin, they can be touched with their hands. uncomfortable!
Answer: Leaving aside the aisle, a good golden ratio effect is the distance between floor in the living room and lamp. In a restaurant, this distance is usually between 0.85 m and 0.95 m.
We buy lights today not just for illumination, but for their decorative and illuminating effects, in order to create a comfortable and warm home.
What is the best wattage to choose?
In general, 30-40 watts of light is best for 15 square meters.
In general, 70-75 Watt lights are better for a living room that is 15 to 20 square meters. It is best to use 80-90 Watt lights for 20-25 Square Meters. If you have more than 25 square metres, then 105-watt LED lights are better.
Our common lamps:
Light strip
Most flexible light strips today are , but LED has now come out with T5, which can be brighter and more durable than light strips.
It is easy to replace a broken section of the middle because it is connected one-by-one. The light strip is easier to install.
The following are some examples of the use of spotlights
The light can be focused and the angle adjusted. It can be used to highlight certain points. Designers use spotlights as a way to emphasize the effect.
Downlight
It’s flat and its main function is to enhance lighting.
Use of 3.5-watt downlights is recommended. The hole in the ceiling should be 7.5-8cm.
In general, it is recommended to use a downward light at a distance no less than 60 cm. Even 80 cm, or 1 meter is acceptable. The number of pieces should be kept to a minimum if it’s used for decoration.
molecular lamp
The material used for the LED household lights and lamp body as well as its workmanship are the main factors that determine the choice of molecular lamps.
Suitable for Nordic style decor
All copper lamp
All-copper lamps cannot be made of copper. Copper is a relatively soft metal, so it can slip easily. Copper lamps must meet a 60% copper standard.
Decor is more often influenced by American and European styles.
corn light
The big corn brands aren’t doing much because of technical bottlenecks, and it is difficult to maintain quality.
Its light-emitting surface is quite large. This corn lamp can be used if you purchase a chandelier that comes with a lampshade. Corn is not recommended.
Halogen lamp
Halogen lamps emit a yellowish light with a color temperature below 3000k. The color temperature is too high and is bad for your eyes.
Filament bulb
These are imitations of the old tungsten filament lamps, which were high-wattage bulbs. They are not made by many domestic factories. The majority of filament bulbs today have a color temp of 2700. This is used to create an atmosphere. This may make lighting a bit worse.
If the lamp is simple or European, this type of LED bulb will look better with many Nordic and American lamps. Placing a filament light bulb in a lamp may not look great.
