Top 10 Choose LED Panel Light Experience

When choosing panel lights pay attention to the panel light quality assurance, size, color temperature, workmanship, installation methods, whether to support intelligent control and so on. General panel lights have two structural ways, one is the side light-emitting, and one is straight down type. Side light-emitting structure has the advantages of a thinner volume and uniform light. And straight-down type has the advantage of greater luminous flux and brightness.

So how should we choose LED panel lights?

1. Panel light appearance characteristics

According to the shape, shape, and style characteristics.

There are square panel lights, rectangular panel lights, round panel lights, and shaped panel lights that are irregularly shaped, such as leaf-shaped panel lights, and diamond-shaped panel lights. Specific needs according to their preferences, and the existing decoration style to determine.

2. Panel Light Size

The size of panel lights is 7 inches, 9 inches, 12 inches, etc.

Usually, use the length of the two sides to indicate the size of the panel light, common 300mm * 300mm, 300mm * 600mm, also write 30cm * 30cm, 30cm * 60cm or 3030, 3060.

Generally speaking, 300mm * 300mm is suitable for 3-8 square meters of the room, the power is about 10w, and 300mm * 600mm suitable for 6-12 square meters of the room, the power is generally in 18W, or so, the specific application area and power due to various manufacturers of light sources, optical design, structural design, light output rate and will vary.

Common size and 300mm * 1200mm 600mm * 600mm and 600mm * 1200mm and other different specifications. Of course, it can be customized according to the need, but there will be a number of requirements.

3. Optical performance of panel lights

Comprehensive technical specifications include:

Optical performance includes spectral, chromaticity and luminosity, such as peak wavelength of luminescence, spectral bandwidth, axial luminous angular intensity, color temperature, color tolerance, luminous flux, radiation flux, luminous efficiency, color product coordinates, color purity, main wavelength, color rendering index, illuminance, light intensity, for white LED, color temperature, color rendering index, and illuminance are the most important technical indicators.

We are daily use, and mainly with white light to lighting, focus on the light intensity, luminous flux, color rendering index, color temperature, etc.

  • The color temperature of panel light

Panel lights are usually installed in kitchens, bathrooms, offices, etc., where the brightness needs to be high, so it is also common to choose cool light, with a color temperature of 5000k or more. Of course, the color temperature of panel lights from low to high color temperature are available, you can choose according to their needs.

  • The brightness of the Panel Light

The brightness of the panel light is usually related to its power size and luminous flux, the higher the power, the greater the luminous flux, the same light output area, and the brighter the panel light will be.

  • According to the light characteristics of the panel light, there are two types of panel lights

One is the backlit panel light, this type of panel light uses the diffusion plate and the related optical design of light mixing, generally thicker, uniform light, with high brightness.

One is the side light-emitting panel light, this type of panel light uses the light guide plate to achieve the uniform light effect, the brightness is lower, and the process requires higher, generally thinner.

4. Heat dissipation performance and structural design of panel lights

As LED is a semiconductor light-emitting device, it is very much affected by heat, so its PN junction temperature and the overall thermal performance of the luminaire are very important. Generally top-notch luminaires, that is, the LED from the package level to the overall luminaire heat dissipation structure, but also fully consider the aesthetic appearance of the structure.

Some expensive chips, leading technology, and materials are used. Such as high thermal conductivity long life chip binder, ultra-low thermal resistance materials, control of the overall thermal resistance, and light source module temperature in the lowest possible temperature in general we should also consider the use of good thermal structure and thermal materials, such as aluminum material thermal performance or can be. The poor thermal performance will seriously affect the brightness and light decay of the lamps, which in turn affects the service life of the lamps.

5. Electrical performance of panel lights

-Power supply performance

Common is a constant current drive, the higher the efficiency the better, and the higher the output current stability of the power supply the better, that is, the smaller the ripple current the better. The higher the power factor of the power supply, the better, which means that the power supply has a small impact. The higher the efficiency of the power supply, the better, which means that the power supply has high conversion efficiency and energy saving.

-Power size

Can be combined with the size of the room, the size of the lamp, and the brightness needed to choose. Generally speaking, the power of the panel light and its size is closely related. Can be combined with the following panel light size reference.

6. Panel Light Materials


Choose a high-strength frame, that can make the lamp more durable, commonly used materials include aluminum, PC, steel, etc.

-Diffusion plate

The role of the diffusion board is to spread the light evenly and to choose a good light transmission rate of materials, such as acrylic, PC, PS, etc. In general, the acrylic light transmission rate of 92%, but the anti-aging effect is slightly worse, so you have to make your own trade-off.

-Light guide plate

The role of the light guide plate is to reflect light and guide the light, which directs the entire light efficiency and light decay. The role of the light guide plate is to reflect light and guide the light, which directs the whole light efficiency and light decay.

7. Panel light installation method

The advantage of concealed installation is beautiful and generous, but the brightness is affected.

Concealed, embedded installation Generally used in the installation of integrated ceiling, installation is relatively simple. Remove the cover plate and use the luminaire spring snap to install it.

Concealed installation There is another kind of installation for the traditional ceiling, which requires a carving knife to carve out the installation range, and the installation process is slightly complicated.

The advantage of open installation is that the brightness is given full play, but the aesthetic effect varies from person to person

The common way of bright installation is the hanging installation, the need to use the hanging line.

8. Look at the panel light workmanship situation

Panel lights of many internal electrical characteristics, the quality we usually can not intuitively see, but see whether the workmanship is fine, to a certain extent reflects the quality of the product.

9. The sealing of the panel light

Panel lights have a simple housing design and good sealing performance, which can avoid dust from entering and bring convenience to maintenance and cleaning.

10. The waterproof situation of the panel light

Because panel lights are often used as kitchen and bathroom lights, the environment is more humid, even if it is used in the kitchen, or bathroom dry area, panel lights should also have a certain waterproof level to adapt to the use of the kitchen and bathroom.
