LED panel light has the characteristics of good uniformity of illumination, high color rendering index, soft and comfortable light. It is one of the commonly used lamps for office lighting, school lighting, hospital lighting, shopping mall lighting and home lighting.
First of all, LED panels have different classifications according to lighting functions and requirements. When selecting panel lights, you must choose according to the lighting requirements of the lighting place.
How to choose a suitable LED panel light?
LED panel light
According to the shape:
LED panel lights can be divided into square, rectangular, round, outer and inner circle, etc. Different sizes of panel lights should be selected for different environments, such as rectangular rooms, rectangular panel lights should be used, and round lights can be selected for warmth LED panel lights.
According to specifications:
30x30cm, 30x60cm, 30x120cm, 60x60cm, 120x60cm, etc. If you have a smaller space, you can choose a smaller panel light, and if you have a larger space, choose a larger one.
By color temperature:
Warm white light 3000K, natural light 4000K, cool white light 6000K. Warm white and natural light will give people a warm and warm feeling, suitable for use in hotels, hotels and bedrooms. Cool white light can be selected for places with high lighting functions, such as office places.
According to the installation method:
There are mainly flat type (T-shaped keel), embedded type (opening), buckle type (triangular keel); suspension type and ceiling type.
According to the way of light:
There are mainly two types of side-emitting LED panel lights and back-emitting LED panel lights (direct type). (That is, side-entry type and direct-type type), generally speaking, the energy efficiency of back-emitting LED panel lights is higher than that of side-emitting LED panel lights, and the cost is also lower.
Toning by dimming:
Mainly include ordinary non-dimmable and color-modifying LED panel lights, dimmable LED panel lights, color-tunable LED panel lights, dimmable color-tuning LED panel lights, dimming and color-tuning refers to adjusting the brightness and color of LED panel lights. Choose according to lighting needs.
Press smart function:
There are non-smart LED panel lights and smart
After choosing the type of LED panel, we also need to observe the specific parameters of the LED panel light.
1. Focus on the chip
The chip is the core light-emitting element of the LED lamp, and the luminous efficiency and color rendering index of different brands and models of lamp beads are different. Therefore, when purchasing, pay attention to the quality of the chip. A good chip not only has a long service life, but also has a relatively high luminous efficiency and color rendering index, and is used in a wider range of occasions.
2. Pay attention to luminous flux
Luminous flux generally refers to brightness. Different environments and different areas require different light. Under the same level, the number of LED lights used is different according to different environments. When buying, you can consult the sales staff according to your own space needs. When choosing lamps, it is necessary to consider the lighting environment, refer to the luminous flux index of the product, or pay attention to the brightness of the light, and try to choose a lamp with sufficient brightness but not glare.
3. Pay attention to the color rendering index
The color rendering index is to see the true degree of the color of the object under the light. The value is generally 0-100. Now the color rendering index of LED lights is greater than 75. It is recommended to choose 80 or more.
Fourth, carry out stroboscopic test
Observe whether the LED lights flicker, the stroboscopic lamps will affect your eyesight. Stroboscopic is a problem that is difficult to observe with the naked eye. You can use your mobile phone to aim at the illuminator to take pictures. Adding the gray and white "stripes" in the photo indicates the stroboscopic. If it does not appear, there is no stroboscopic.
Five, look at the uniformity
To look at the uniformity is to look at the luminous uniformity of the LED panel light. Generally, the luminous uniformity needs to be >75. The higher the uniformity, the better.
Six, look at light decay
LED light attenuation means that after a period of time when the LED is lit, its light intensity will be lower than the original light intensity, and the lower part is the LED light attenuation. The smaller the light decay, the better the performance of the LED panel light!
Above, we have explained the classification and various parameters of LED panel lights. I believe that everyone has a preliminary understanding of how to choose a suitable panel light. In the future purchase process, you can fully consider specific environmental applications and specific needs. Choose the right led panel light.
