How to choose LED downlight LED downlight purchase points

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, the radiator is too small to accumulate high temperature inside the light source, and the lamp beads work in a high temperature state for a long time, the light decay is very fast, and the service life is also very short, so when choosing LED downlights, it is recommended that you should choose the shell made of aluminum, because the heat dissipation coefficient of aluminum is relatively high, and the heat dissipation is relatively fast, which can ensure the normal lighting of LED downlights.

LED downlight purchase point 2: drive power supply.

The driving power supply is also called the transformer, and the quality of the transformer also determines the life of the whole lamp, and the lamp beads are no problem when used for more than 50,000 hours, but if the transformer is broken, the whole lamp will not be able to light up. The electronic components and design scheme used in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer, so when buying LED downlights, it is recommended that you choose a wide voltage drive, so as to ensure the stability of the output current and voltage, and then ensure the safety and stability of the LED downlights in the process of use.

LED downlight purchase point 3: lamp bead quality.

In addition to considering the material and driving power supply, the purchase of LED downlights also focuses on the quality of the lamp beads, which determines the lighting effect of the lamp, and the packaging process affects the quality of the lamp beads, heat dissipation and other key factors. At present, the LED lamp bead chips sold on the market are domestic and imported, generally different brands, the price difference is large, and the lighting effect is different, so it is recommended that you be cautious enough to buy.
