How to replace the integrated ceiling light and how to judge whether the size of the ceiling light is suitable?
The replacement of the integrated ceiling light is actually very simple. In the case of power failure, use the suction cup to remove the module next to the light, and then take out the bottom of the light. Be sure to pay attention to the electricity.
How to tell if the ceiling light is the right size?
1. The overall effect: the whole body is bright.
After the light is turned on, a good ceiling light is bright and has no dark spots, and many ceiling lights with a larger wattage often inevitably have a dark dark spot in the corner. block, affecting the overall aesthetics.
2. Lampshade selection: The acrylic mask is soft and has good light transmittance.
A mask, soft is better for light transmission than hard. But be careful not to be too thin on the edge, otherwise it is easy to break.
The most common ceiling light masks on the market now are acrylic masks, plastic masks and glass masks, the best is the imported acrylic mask that has been stretched twice. Acrylic is a kind of plastic, which is characterized by softness, lightness, good light transmission, not easy to be dyed, and will not turn yellow due to chemical reaction with light and heat. In addition, in terms of safety, the fume hood of the ceiling lamp should be a material that is not easily damaged, especially in families with children, when throwing toys will hit the lamp hood, so it is best not to choose a ceiling lamp with a glass cover.
3. Phosphor selection: three primary toners are energy-saving.
The circular lamps of the ceiling lamps have halogen powder and three-base color powder. The three-base color powder lamp has good color rendering, high luminosity and slow light decay; halogen powder lamp has color rendering Poor performance, low luminosity, fast light decay. Tri-color energy-saving lamps are about 80% more energy efficient than incandescent lamps, and about 44% more energy efficient than ordinary halogen powder fluorescent lamps.
In addition, three primary colors, soft light, high color rendering, that is, natural light color, and the light color of some brand-name ceiling lamps tend to be blue, although it seems to be very bright, but this kind of light source is more Poor, not only the object to be illuminated will look discolored, but also have a bad effect on vision.
Distinguish halogen powder and tri-color toner lamps, can light two lamps at the same time, put your hands near the two lamps, you can find that the hand color is whitish and distorted under the halogen lamp light, three primary colors The color of the hand under the light of the pink lamp is the true color of the skin.
4, the color temperature should not be too high, choose your own coup.
Color temperature is the temperature of the color of the light source, which is commonly referred to as “yellow light” and “white light”. In the industry, it is usually expressed by a numerical value, yellow light is “below 3300k”, white light is “above 5300k”, and there is an intermediate color “3300k-5300k”.
Why do some ceiling lamps look brighter, some look dark, some light color is white, and some are purple or blue? This is due to the difference in light efficiency and color temperature of the light source. Some small manufacturers produce light sources with low light efficiency, but in order to make the customer look brighter, the color temperature is increased to make it look brighter. It’s not really bright, it’s just an illusion of the human eye.
So when we buy a ceiling lamp, we should pay attention to the color temperature. Here is a relatively simple and effective method: to judge whether the color temperature of a light source is too high, stretch your hand to the side of the light source and see the color of the palm. Or purple, it means the color temperature is too high.
5. Ballasts: Electronic ballasts improve the light efficiency and life of lamps.
All fluorescent light sources require a ballast to be lit. The ballast can bring instant start-up voltage and stable voltage during operation to the light source. Whether it is good or bad directly determines the life and light efficiency of this lamp.
There are two types of ballasts: magnetic ballasts and electronic ballasts. Compared with magnetic ballasts, electronic ballasts can improve the light efficiency of lamps and systems. lifespan. At the same time, it has small temperature rise, no noise, small size and light weight, and its power consumption is only 1/3 to 1/4 of that of inductive ballasts, so it is best to choose electronic ballast ceiling lamps.
6. Installation and cleaning should be convenient.
The last thing to look at is, of course, whether it is easy to install and whether it is easy to clean, but this is generally not a problem.
