The advantages and disadvantages of LED panel lights

In recent years, we have seen more and more LED panel lights in the market. From the old-fashioned dark lights that are usually only used and used in offices, to the decorative decorations that can now be seen in commercial and residential applications. LED panel light has wide-angle light output and low glare effect, which is very practical. This passage is going to talk about the advantages and disadvantages of LED panel lights.


This article contains the following:

disadvantages of LED panel lights 

(1) advantages

The spectrum of indoor light is almost entirely concentrated in the visible light frequency band, and its luminous efficiency can reach 80-90%. The light efficiency of ordinary incandescent lamp is 12lm/w, the life is less than 2000 hours, the light efficiency of spiral energy-saving lamp is 60lm/w, the life is less than 8000 hours, the T5 fluorescent lamp is 96Alm/w, the life is about 10000 hours, and the diameter is 5 The millimeter white LED is 20-28lm/w, and the life span can be more than 100,000 hours. Someone also predicts that the upper limit of LED life will be infinite in the future. Most people think that energy-saving lamps can save energy by 4/5 is a great innovation, but LED is more energy-efficient than energy-saving lamps by 1/4, which is a greater reform of solid-state light sources. In addition, LED panel light also has other advantages, high light quality, basically no radiation, is a typical green lighting source; reliable and durable, extremely low maintenance costs and so on. Because LED has the characteristics that other solid-state light sources cannot match above, LED will be the mainstream light source in the lighting industry in the future.

The LED panel light is small in size and light in weight, and the outer shell is epoxy resin encapsulation, which not only protects the internal chip, but also has the ability to transmit light and condense light. The service life of LED is generally between 50,000 and 100,000 hours, because LED is a semiconductor device, even if it is frequently switched on and off, it will not affect the service life. 

LED can be driven by low-voltage direct current: it has the advantages of small load and weak interference, and lower requirements for the use environment. The indoor light can control the size of the semiconductor light-emitting layer and the forbidden band width of the semiconductor material to emit light of various colors with higher chroma. Not only that, LED panel light has high color rendering: it will not cause harm to human eyes.

 

(2) disadvantages

Inferior products in the industry mostly use inferior lamp beads with low price and quality, which have small chips and low light output. At the same time, its packaging gel and phosphor are all low-cost configurations, and use copper wire with low melting point (quality lamp beads use gold wire), iron bracket (quality lamp beads use copper bracket or high thermal conductivity synthetic material), so that in the use process it is very easy to burn out into a dead lamp.

As LED lamp beads belong to low-voltage startup semiconductor devices, they need to be driven by a matched low-voltage power supply. In order to achieve better light extraction efficiency, the LED panel light string generally has a slender structure. Therefore, in order to ensure the heat dissipation of the LED light, an all-aluminum structure is now used as a cavity and as a heat sink. The non-insulating nature of the aluminum lamp body requires the use of an isolated power supply to have basic safety protection, and at the same time, it can provide a continuous constant current to ensure the long life of the lamp beads. Therefore, inferior products in the current industry may cut corners and use inferior drive solutions.

 

We hope this article can help you understand more about the advantages and disadvantages of LED panel light. We have a wide range of products. We have 4 inch and 6 inch led panel light. We have 9w and 15w panel light. And we also have downlight for indoor lighting. Our product all passed the ETL test, which are all good ETL panel light. If you need a LED panel light, Downlights, Linear Lights please contact us.
