I believe that many consumers can find the information of LED panel lights in their homes. It can be used as room lighting, and it can also be a good helper for background wall decoration. Not only that, LED panel lights also play an important role in the lighting of office spaces and some large supermarkets.
For LED panel lights, some friends can definitely recognize it at a glance, but what if I say LED panel lights information? There must be very few that can be said. The following will explain the types and related content of LED panel light information. I hope you have a deeper understanding of this environmentally friendly lighting product.
The variety of LED panel light information is very rich, but it can basically be divided into three categories:
LED panel light information one
For LED panel lights made of 3528 or 5050 SMD mid-power LEDs, the power supply also generally uses resistance-capacitance step-down circuits, and some LED panel light manufacturers use constant current circuits. Compared with straw hat LEDs, SMD LEDs have better heat dissipation. , There is a thermally conductive substrate, and when combined with an aluminum substrate, part of the heat can be discharged.
Let me reveal another LED panel light information. Because the heat of the LED is still ignored, many medium-power SMD LED panel lights do not have a radiator and still use a plastic shell, and the light decay is still serious. The use of resistance-capacitance step-down low-end power supplies, due to unstable grid voltage, current fluctuations, and brightness fluctuations, the price is moderate, and the quality is slightly better.
LED panel light information two
For LED panel lights made of high-power SMD LEDs, the power supply generally uses a constant current isolation circuit, that is, there is a constant current, such as a 5W LED, usually 5 1W LED chips, connected in series, and a constant current 300mA Current source power supply, wide voltage power supply, when the power grid fluctuates, the current does not change, the luminous flux, that is, the brightness remains constant, 5 SMD LEDs are welded on the aluminum substrate, and the aluminum substrate is combined with the radiator. The heat can be used quickly and quickly Disperse to ensure that the temperature of the LED chip is lower than the allowable junction temperature of the LED, thereby ensuring the true effective life of the LED panel light. This kind of LED panel lights are high in price and good in quality, which is also the development direction of LED panel lights.
LED panel light information three
The LED energy-saving lamp made of straw hat-shaped low-power LED, the power supply adopts a resistance-capacitance step-down circuit.
The straw hat type LED continues to use the encapsulation form of the indicator LED, epoxy resin encapsulation, so that the LED chip cannot dissipate the heat, and the light decay is serious. After using for a period of time, the color temperature of many white LEDs becomes higher and gradually turns blue. It becomes dim. There are also manufacturers dedicated to the development of straw hat LEDs with low luminous decay. However, the luminous decay has not changed a lot because the packaging form has not been changed. This kind of LED panel light products are transitional products with low price and poor quality.
In fact, there is still a lot of knowledge about LED panel lights. When consumers want to buy, they must understand its performance and use environment, so that they can buy the most satisfactory products.
