LED panel light classification, advantages and disadvantages and development trend analysis
May 04, 2022
LED panel lights are more widely used in the scene is mainly home decoration in the kitchen, bathroom and school, hospital, office space, etc., can be said to be very common.
Then how much do you know about LED panel lights?
Although embedded in the ceiling after the different types of LED panel lights do not see any difference, but in fact you see the same light is likely to belong to a different kind.
According to the light-emitting mode, LED panel lights are divided into side entry and straight down two types.
Side entry LED panel light source is distributed in the side of the panel light, through the light guide plate for lighting.
Straight down LED panel light source is evenly distributed on the back panel, directly through the diffusion plate for lighting.
We are going to say the point LED panel light is the straight down panel light.
Straight down panel lights have several advantages over side entry panel lights.
First, high light efficiency. Directly under the LED panel light emitted by the diffuser plate directly out, without the need to pass through the light guide, improve the luminous efficiency of the lamp.
Second, low cost. Save the cost of the light guide plate, so that the cost of lamps and lanterns to reduce the internal space, the design is also more flexible.
Third, light lamps and lanterns. Because of the omission of the light guide plate, the quality of lamps and lanterns to reduce.
Fourth, high reliability. In the design of the lamps and lanterns, the performance of each component and the materials used will determine the overall performance of the lamps and lanterns, the more components in the lamps and lanterns, the lower the reliability performance.
And side entry panel light guide plate and reflective film has been exposed to high temperature, easy to aging yellow, affecting the light efficiency and service life.
And side entry panel light compared to the straight down panel light is also some disadvantages.
First, the straight down LED panel light can not be made too thin. Usually its thickness are more than 3 cm, much higher than the side entry LED panel lights of no more than 15 mm.
The reason for this is that the light source and the diffusion plate between the need for a certain spacing, otherwise the light will produce bright spots.
Thickness increased, the cost of straight down LED panel light fixture housing will also follow the increase, while because the light propagation path longer, the luminous efficiency of the lamps will also be reduced.
RINA TECH has found a solution. It uses precise light distribution technology to reduce the thickness of the straight down LED panel light to 3 cm, which greatly improves the light efficiency and reduces the cost of the light housing.
Second, as the lamp beads are fixed on the back panel, the fixing and positioning of the lamp beads, etc. is another problem. And with the increase of LED panel light area, long time hanging back plate deformation bending and other problems also limit the development of straight down type LED panel light.
Dot new LED panel light uses a patented panel light structure technology, effectively solving the problem of unstable LED panel light structure.
Of course, LED panel lights are not the only advantages, energy efficiency, price and maintenance costs are also the problems of LED panel lights.
In order to solve these problems, the development of LED panel lights have the following trends.
First, further improve the light efficiency. In the light body thickness more dominant side entry LED panel lights, low light efficiency is a problem. How to maintain the thickness of the premise to improve light efficiency, is the side entry LED panel lights need to develop the direction.
Straight down LED panel lights want to continue to improve the light efficiency, you need to work from the mask material. Point lighting new LED panel light using high light-transmitting PP material as a lampshade, in improving light efficiency at the same time, but also effectively reduce the dark area of light.
Second, to further reduce costs. For side-entry LED panel light, its high cost comes from the light guide; for straight down LED panel light, its additional cost comes from the shell cost brought by the thickness of the light body. How to reduce these costs, is the direction of the LED panel lights need to consider.
Third, to further reduce the maintenance difficulty. Ceiling lights and other lamps and lanterns if the light source is bad, do not need very professional people can easily replace one-to-one, while the LED panel lights need to repair or replace, usually need more professional personnel to operate, maintenance to trouble many. How to make the LED panel light more convenient to use, is also a manufacturer needs to study the problem.
This time point lighting new LED panel light and come up with a patent for LED panel light installation structure, so that the panel light installation and removal more simple, but also reduce the cost.
