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 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. Let’s start with the driver. Normal household LED lights generally choose non-isolated drivers. This driver has average cost, high efficiency, and good reliability. Voltage fluctuations do not affect the lights’ ability to work.
However, in order to compete with prices in the current market, many companies will use resistor-capacitor step-down or linear power supplies instead of non-isolated power supplies. These two power supplies have poor impact resistance. It is likely that a nearby storm will cause a surge in voltage. , can only work at the set voltage.
For example, 220V, as long as the voltage fluctuates, the light will also fluctuate, so when purchasing, be sure to 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.
Next, let’s talk about the light source board. Currently, the majority of LED light sources are welded to the aluminum substrate. It is difficult to see the quality of the light source with the naked eye, but generally it is not a problem after a few years of use. 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. This is what is call-ed blue light hazard, so do not choose a color temperature above 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.
Generally, the bulbs on the market are plastic-coated aluminum heat sinks, which means they feel like plastic to the touch. There is a layer aluminum in the bulb.
The greater the power of the LED, the greater the heat. The heat sink usually has a power limit. So, when purchasing a lamp do not go overboard with power. Generally, the A60 should not exceed 10 watts. It will be discounted if it is over the lifespan.
How to choose 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.
It is upload-ed online that you can use your mobile phone to judge the strobe of LEDs. 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 aren’t required.
It is recommend-d to use neutral light with a color temperature of 4000K for children’s rooms
The living room can use lights that convert between three color temperatures (neutral light, white light, yellow light)
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.
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:
- 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 lampshades are relatively thick, so it is recommend-ed to use white light bulbs.
- Choose the right size
- The style should match the overall decoration style of the home.
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 are more suitable.
- 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!
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. For 20-25 square meters, it is better to use 80-90 watt lights. For more than 25 square meters, it is better to use LED lights of 105 watts.
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. Generally, it can be use-d to highlight a certain point position. 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. 80 cm or even 1 meter are also acceptable. If it is use-d for decoration, the number should not be too many.
molecular lamp
The choice of molecular lamp mainly depends on the material of its household LED lights source and its lamp body, as well as the workmanship of the glass lampshade.
Mainly suitable for Nordic style decoration
All copper lamp
The so-called all-copper lamp cannot be all copper. Because copper is relatively soft, it slips 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. 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. 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. Currently, not many domestic factories can make them. Most of the current filament bulbs have a color temperature of 2700, which is generally use-d to create atmosphere. It may be a little worse for lighting.
This kind of household LED lights bulb looks better when used with most Nordic and American lamps, if it is European or simple. Placing a filament light bulb in a lamp may not look great.
