How to choose LED downlights, briefly describe the key points of LED downlights

December 20, 2023

It is simple and straightforward to say that LED Downlights are actually lighting fixtures for home use in the daily life (bedroom, living room, balcony, etc.), but the light source is no longer a traditional energy-saving light bulb, but LED light source illumination, LED Downlight The choice is no longer as simple as a traditional energy-saving lamp (incandescent lamp), so the factors to be considered are different. So, how do we choose LED Downlights?

LED Downlight purchase point 1: radiator.

The speed of heat dissipation determines the degree of light decay and the length of service life of the LED Downlight. If the heat sink is too small, the high temperature will accumulate inside the light source, and the lamp bead works under high temperature for a long time. The light decays quickly and the service life is very high. Short, so when choosing LED Downlights, it is recommended that you choose the outer casing made of aluminum, because the aluminum has a higher heat dissipation coefficient and faster heat dissipation, which can ensure the normal illumination of the LED Downlight.

LED Downlight purchase point 2: drive power.

The drive power is also called the transformer. The quality of the transformer also determines the life of the whole lamp. It is no problem to use the lamp for more than 50,000 hours, but if the transformer is broken, the whole lamp will not shine. The electronic components and design schemes used in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer. Therefore, when purchasing LED Downlights, it is recommended that you choose a wide voltage drive. The output current and voltage are stable, which ensures the safety and stability of the LED Downlight during use.

LED Downlight purchase point 3: lamp quality.

In addition to considering the material and driving power supply, the LED Downlight should also consider the quality of the lamp bead. The quality of the lamp bead determines the lighting effect of the lamp, and the packaging process affects the key factors such as lamp quality and heat dissipation. At present, the LED lamp bead chips sold on the market have domestic and imported, generally different brands, the price difference is large, and the lighting effect is also different. It is recommended that you buy with caution.
