How To select led light panel with good quality and price?
Jul 30, 2021
Panel light is a high-end indoor lighting fixture, which not only has a good lighting effect, but also is very beautiful, suitable for indoor lighting in various venues. How to install the panel light? There are three ways to install the panel light, which are embedded installation, ceiling installation and mosaic installation. Different types of panel lights are suitable for different installation methods. You can choose the installation method according to the style of the panel lights you choose. Although the panel light is durable and environmentally friendly, it still fails after being used for a long time. How to repair the broken LED panel light?
Panel light structure composition
1. Light guide plate for panel light
The light guide plate of the panel light is also one of the most important components of the panel light, similar to the CPU in the computer. The light guide plate of the panel light can make the luminous effect of the entire panel light reach uniformity, which is the key point of the quality control of the LED panel light.
2. Panel light diffuser
The panel light diffuser is one of the main components of the panel light. The main material of the panel light diffuser is acrylic material, which has good light transmittance and can evenly lead out the light source.
3. Panel light aluminum frame
The panel light aluminum frame is the channel for the heat dissipation of the LED panel light. It can be an aluminum frame formed by aluminum extrusion molding, or an aluminum frame formed by pressing.
4. LED light source
LED light source refers to LED lamp beads. At present, many LED panel light manufacturers on the market basically use SMD3528. Of course, there are also models such as SMD5630 and SMD3014. The price and performance of different models are different.
5. Reflective paper
The main purpose of the panel light reflective paper is to reflect the remaining light on the back of the light guide plate to improve the light efficiency.
6. Drive power
There are two mainstream models of panel light driving power, which are constant current driving power, constant voltage and constant current driving power. The cost of the latter is higher than the former, but the quality will be better.
7. Rear cover
The rear cover of the panel light is used to seal the lamp body, the main material is aluminum, so it also has a little heat dissipation effect.
LED panel light size specifications
The more common sizes of LED panel lights are 600*1200mm, 300*1200mm, 600*600mm, 300*300mm, etc. Panel lights of different sizes have different numbers and luminous fluxes.
The difference between panel light and flat light
Flat panel lights and panel lights are generally considered to be the same, but because LED panel lights look like a flat panel, they are sometimes called LED panel lights. In fact, the two refer to the same thing.
The difference between panel light and downlight
1. Different power
The general power of panel lights is larger than that of downlights. Most of the power of panel lights is basically above 8w, while the power of downlights can be as low as 3w.
2. Different applicable occasions
Panel lights are mainly used for kitchen and bathroom decoration, and small wattage downlights are mainly used for home living room decoration.
The difference between panel lights and ceiling lights
1. The price is different
The price of ceiling lights is lower than that of panel lights. The price of general LED ceiling lights is below one hundred yuan, while the average price of panel lights is basically above one hundred yuan.
2. Different uses
Led ceiling lights are mostly used in homes, corridors, and aisles, while panel lights are mostly used in commercial lighting and office lighting.
What kinds of panel lights are there
Model distinction
According to the style of panel lights, it can be divided into flat panel lights, embedded panel lights, ceiling panel lights, hanging panel lights, round panel downlights, round ceiling lights and other types.
Lighting mode distinction
According to the lighting mode of the panel lights, the panel lights can be divided into two types: direct-lit panel lights and side-emitting panel lights. Side-lit panel lights are light and thin, but they tend to emit unevenly. Direct-lit panel lights have sufficient brightness, but glare is inevitable.
Power distinction
Common panel lights on the market have rated powers of 60W, 26W, 19W, and 9W. The greater the power, the greater the number of lamp beads and the greater the luminous flux.
How to choose a panel light
Look at the light
The light color of the panel light is very important, it will directly affect the experience of use. There are two types of common panel lights: yellow light and white light. When choosing yellow light panel lights, be careful not to turn red, while white light panel lights should not be blue or green, otherwise it will damage your eyesight. In addition, the entire lamp should emit light evenly, without dark areas.
Select material
The main material of the frame and the back cover of the panel light is aluminum. When selecting, you can choose a thicker base plate as much as possible. At the same time, you can compare the average area of the aluminum substrate on the back of each LED. The larger the heat dissipation, the better the quality. Guaranteed.
Price and brand
When choosing panel lights, you can also start from the perspective of price and brand. Generally speaking, cheap is definitely not good. Don't try to buy inferior panel lights cheaply. This is harmful to your eyes. You can choose a well-known brand of panel lights, and the quality will be relatively guaranteed.
