How to buy spotlights for decoration? What are the "five parameters" of spotlights?

In recent years, in the decoration, people pay more and more attention to the role of lighting in creating the atmosphere of the whole house, rather than using lighting as a lighting tool! Especially when many friends accept the design of the main light more and more, choosing a good spotlight directly determines the effect of the whole house lighting. So people say, "Choose the right spotlight, and the sense of advanced will multiply!" "In this article, I want to share with you how to choose a good spotlight:

First, distinguish between downlights and spotlights. If you want to choose the right spotlight, you must first distinguish the difference between downlight and spotlight. Many white people made a mistake at the first step! You can tell the difference by looking at the lighting effect. Those with hills are spotlights, and those with scattered light and shadow are downlights.

1. downlight. The downlight cannot adjust the lighting angle because it is a floodlight. The light distribution of the downlight is uniform, which can play a good lighting role. Downlights are generally used in walkways, bathrooms and kitchens.

2. shoot the light. The illumination angle of the spotlight can be adjusted. After the light source emits light, it is reflected by the interface of the lampshade to form a light beam, which can emphasize the visual effect and enrich the spatial level. Spotlights are generally installed above decorative items such as green plants, sculptures and paintings, and above functional areas such as toilets and basins.

Two, choose the spotlight 1 need to pay attention to five parameters. Beam angle. The beam angle is the angle between the beams emitted by the spotlight. General household needs 24 degrees and 36 degrees. The smaller the angle of beam angle, the more concentrated the light, and the sharper the hills and peaks. Of course, the effect of beam angle is also in line with the distance from the wall when installing. For example, for a beam angle of 24 degrees, the recommended distance from the wall is 18 cm, which is the most effective.

2. Color temperature. Color temperature is the hue and temperature sense of light. The lower the hue value, the warmer it is, and the higher it is, the colder it is. The color temperature of general household spotlights is 3000k to 4000k K, and different color temperatures have different atmospheres. Friends who like warm atmosphere suggest choosing 3000 K to 3500 K; If you like a brighter one, choose one above 4000 K.

Also give a reference for selecting color temperature according to space:

(1) Living room and corridor: It is suggested to choose 4000k warm white light uniformly, which can make the living room brighter.

(2) Bedroom: It is recommended to choose 3000k warm yellow light, which can make the bedroom look warmer and help you sleep.

Special attention: remember to choose the same color temperature in the same space. The color temperature of spotlights in the same space is different and extremely uncoordinated.

3. Watts. Wattage directly affects the brightness of the lamp. Generally, the wattage of spotlights used for wall washing can be 7 watts, which will not be too dark or overexposed. If other spaces require higher brightness, you can choose higher wattage accordingly.

4. Color rendering index. This color rendering index is the ability of the light source to restore the true color of the object. The larger the number, the better. The higher the color rendering index, the closer the color of the illuminated object is to the real color of the object. When selecting, it is suggested that the color rendering index should be above Ra95, so that the color will be more balanced and beneficial to vision protection, so that the photos we see and take will be closer to the original color of the object.

5. The number of shadow angles. The larger the shading angle, the deeper the light source chip can be hidden, and the better the anti-glare effect can be. Only in this way can the spotlight create an advanced sensory effect of seeing light but not seeing light. Some brands do not indicate the degree of shading angle, but they will definitely indicate "cup depth" or "tube depth". Therefore, try to choose deep cups and anti-glare lamps to achieve the effect of "seeing the light but not seeing the light" as the designer said.

For some scenes commonly used in daily decoration, I would like to make a suggestion:

(1) floodlighting: beam angle is selected as a 58-degree spotlight.

(2) wall washing: choose 36-degree beam angle spotlight.

(3) Lighting decoration: Choose 24-degree beam angle, which is very focused and has a feeling.

If it is difficult to choose, you can actually focus on the 24-degree beam angle spotlight, which has the widest application range.
