Simply put, LED downlights are actually household lighting fixtures (bedroom, living room, balcony, etc.) in daily life, but the light source is no longer traditional energy-saving bulbs, but uses LED light sources to illuminate, LED downlights The choice is no longer as simple as traditional energy-saving lamps (incandescent lamps), so the factors considered are also different, so how do we choose LED downlights?
LED downlight purchase key 1: radiator.
The speed of heat dissipation determines the luminous decay of the LED downlight and the length of its service life. Too small a radiator will cause high temperature to accumulate inside the light source, while the lamp beads work under high temperature for a long time, the luminous decay is very fast, and the service life is very long Therefore, when choosing an LED downlight, it is recommended that you choose an aluminum shell, because aluminum has a relatively high heat dissipation coefficient and heat dissipation is relatively fast, which can ensure the normal lighting of the LED downlight.
LED downlight purchase key 2: drive power.
The driving power supply is also called a transformer. The quality of the transformer also determines the life of the entire lamp. The lamp beads can be used for more than 50,000 hours. However, if the transformer is broken, the entire lamp will not be able to light up. 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 buying LED downlights, it is recommended that you choose a wide voltage drive to ensure that The output current and voltage are stable, thereby ensuring the safety and stable performance of the LED downlight during use.
LED downlight purchase key 3: the quality of the lamp beads.
In addition to considering its material and driving power, the purchase of LED downlights must also consider the quality of the lamp beads. The quality of the lamp beads determines the lighting effect of the lamp. The packaging process affects the quality of the lamp beads, heat dissipation and other key factors. At present, the LED chip chips sold on the market are domestic and imported. Generally, different brands have large price differences and different lighting effects. It is recommended that you buy them carefully.
