Energy-saving lamps have withdrawn from the stage of history. 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. 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.
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. 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.
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. 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. For color temperature, it is generally better to choose a color temperature 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. If it exceeds 6000k, the light is actually bluish. 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.
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. Generally, the heat sink has a maximum power limit, so when buying a lamp, do not be greedy for high power. The A60 is not supposed to exceed 10 watts. If it exceeds the lifespan, it will be discounted.
How to choose LED lights
When we choose LED lights, the most important thing is to pay attention to blue light.
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. There is also a lot of research on LED abroad to solve the problem of blue light. 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. This is not a very accurate standard, and you have to make a comprehensive judgment from all aspects of light color.
Energy-saving lamps and LDE lamps
Compared with energy-saving lamps, LEDs are more energy-saving and can make full use of light efficiency. Especially when the weather is cold, the phosphors in energy-saving lamps need to be fully preheat-ed before they can reach the brightness of 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.
In the living room, ceiling fan lights should not be used. 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:
- 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.
- Choose the right size
- Style should be in harmony with the decor of the house.
The finishing touch is the lamp. We must not only choose the style, but also pay attention to the light color. For simple Nordic style, choose simpler lamps. European and American chandeliers are more suitable.
- Pay attention to the quality and light color when choosing
Popularize the issue of hanging lamp height:
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.
How much wattage should you 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. 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. But the light strip is more convenient 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. If the hole is open-ed in the ceiling, it should be between 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 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
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
Big corn brands don’t do much because they have technical bottlenecks and it’s difficult to achieve stable quality.
But its light-emitting area is large. If you buy a chandelier with a lampshade, you can use this corn lamp. 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
They are actually imitations of previous tungsten filament bulbs, high-wattage filament bulbs. Currently, not many domestic factories can make them. 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.
This kind of household LED lights bulb looks better when used with most Nordic and American lamps, if it is European or simple. Putting a filament bulb may not necessarily look good
