The difference between led tube light and panel light
A large number of led panel lights appear, the purpose is to replace the grille lamp panel, so that the installation becomes simple and easy, the appearance looks a lot more beautiful, but also easy to clean, so it is more popular. However, in general, the light efficiency is lower than that of the grille lamp Bunsen. It is mainly caused by the different light emitting principles. Therefore, under the same illuminance, the power consumption of the led panel light is actually much greater than that of the grille light. This is where the panel lights are insufficient. Due to the high efficiency of LED tube light in the grille lamp, the price is low. The light effect is high.
The principle is the same: LED tube light uses LED lamp beads to be patched on the aluminum substrate, transforms into low voltage through power conversion, and then lights up the led lamp beads to emit light. The led panel light also uses the same light-emitting principle to achieve light-emitting.
The structure is different; the structure of LED tube light is relatively simple. The shell usually adopts an aluminum shell for heat dissipation. The heat dissipation of the light board is different, there are two kinds. One is an aluminum substrate and the other is a fiberglass board. The aluminum substrate has good heat dissipation and is slightly more expensive. Long life and durable. Fiberglass board is cheap and does not dissipate heat well. The light-emitting angle is 80-320 degrees, and the power supply has a built-in external and plug power supply.
Generally used for low-end led tubes. The structure of the led panel light is relatively complicated, and the light emitting method is divided into back light emitting and side light emitting. Among them, the light effect of the back light is higher than that of the side light. However, the side light can achieve a thinner lamp size. The size of the back-illuminated lamps is relatively thick. The panel power supply is generally external. Since the side-emitting light has relatively low light efficiency, the power is relatively large.
The use occasions are different; LED tube lights are used more widely, ranging from factories, enterprises, and schools. As there are different sizes, the small can be 0.3 meters, the large can be 2.4 meters, so it is suitable for many occasions, and it is more flexible and convenient to use. Replacement is also convenient. The old bracket can continue to be used. For inductive ballasts, you only need to remove the starter, which is very convenient and simple to replace
The evolution of led panel lights comes from grille lights. The size of the grille lamp is relatively large, generally at least two LED tubes are installed, and some are installed with 3-4 tubes. This leads to a larger size of the led panel light.
Generally used to replace grille lights. The use range is narrow. The panel lamp assembly takes a long time and has a complicated structure. The use occasions are generally offices and writing rooms. Flexible application in actual replacement.
