How to Choose Household LED Lights

Energy-saving lamps have withdrawn from the stage of history. Almost all household lights are LEDs.

However, there are so many LED lamps on the market that it is difficult to distinguish the good from the bad. This short article teaches you how to choose high-quality LED lamps.

LED lamps are made up of three components: the driver, the light source board and the heat sink. First, let’s talk about the driver. Non-isolated drivers are usually used for household LED lights. This driver is a good choice for its reliability, efficiency and cost. The lights can work normally without being affect-ed by voltage fluctuations.

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. If a nearby thunderstorm causes a surge voltage, it will most likely cause damage. 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.

The chip inside will automatically adjust the duty cycle of the square wave to achieve stable output, so be sure to check the input voltage range when choosing.

Next, let’s talk about the light source board. At present, most of the LED light sources are weld-ed on 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. But you can look at the light on the package. It is better to select a color temperature that is below 6000k. European and American countries like a color temperature of around 3000k, which is slightly yellowish like the sun just rising in the morning.

In our country, we like whiter ones. Generally, 6000k is like the sun at noon. 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. If it exceeds 6000k, the light is actually bluish. This is what is call-ed blue light hazard, so do not choose a color temperature above 6000k.

Finally, let’s talk about 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.

Generally, the bulbs on the market are plastic-coated aluminum heat sinks, which means they feel like plastic to the touch. , there is actually a layer of aluminum inside.

The more power the LED has, the higher the temperature. Generally, the heat sink has a maximum power limit, so when buying a lamp, do not be greedy for high power. Generally, the A60 should not 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 that in the near future we will all be able to use LED lights without blue light.

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 vs LDE lamps

Compared with energy-saving lamps, LEDs are more energy-saving and can make full use of light efficiency. 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 are not requir-ed.

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.

Ceiling fan lights are not recommend-ed for use in the living room. On the one hand, the light intensity is not sufficient, so they can be use-d in the dining room.

As far as household LED lights is concerned, yellow light is less harmful to the eyes, white light is more harmful to children’s eyes, and blue light is only more harmful to children under 8 years old.

How to choose the right lighting fixtures should pay attention to:

  1. If the light of the LED light is bluish, it means there is too much blue light, which is not good. White light is normal.

American-style lamp shades are thicker, so white light bulbs should be used.

  1. The right size
  2. The style should match the overall decoration style of the home.

Lamps play the finishing touch. 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.

  1. When choosing, pay attention to the light color and quality.

Make the issue of lamp height more popular:

Some customers say that the new Chinese-style and American-style lamps are so thin that they can be touch-ed with hands. uncomfortable!

The answer is: leaving aside the aisle, the best effect of the golden ratio is: the distance between the floor and the lamp in the living room is generally 1.8 meters to 2 meters, and the distance between the dining table and the lamp in the restaurant is between 0.85 meters and 0.95 meters.

Nowadays, we buy lights not only for lighting, but also for decoration and light effect, to create a warm and comfortable home.

What is the best wattage to choose?

Generally, it is better to use 30-40 watt lamps for 10-15 square meters.

In general, 70-75 Watt lights are better for a living room that is 15 to 20 square meters. For 20-25 square meters, it is better to use 80-90 watt lights. If you have more than 25 square metres, then 105-watt LED lights are better.

Our common lamps:

Light strip

Nowadays, most of the flexible light strips are use-d, but now LED has come out with T5, which is brighter and more stable than light strips.

Because it is connect-ed one by one, it is convenient if a section in the middle is broken and needs to be replac-ed. The light strip is easier to install.

The following are some examples of the use of spotlights

You can adjust the angle and focus the light. 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.

It is recommend-ed to use 3.5-watt downlights. 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.

American and European styles are more commonly use-d in decoration.

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. If you buy a chandelier with a lampshade, you can use this corn lamp. It is generally not recommend-ed to use corn.

Halogen lamp

Halogen lamps emit a yellowish light with a color temperature below 3000k. It is difficult to have a high color temperature, so it is not good for the eyes and the light environment is not very shaping.

filament bulb

They are actually imitations of previous tungsten filament bulbs, high-wattage filament 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. It may be a little worse for lighting.

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.
