To put it simply and clearly, LED downlights are actually household lighting fixtures (bedrooms, living rooms, balconies, etc.) The choice is no longer as simple as traditional energy-saving lamps (incandescent lamps), so the factors considered are also different, so how should we choose LED downlights?
How to choose LED downlight led downlight purchase points
LED downlight purchase points 1: radiator.
The speed of heat dissipation determines the degree of light decay and the length of service life of LED downlights. If the heat sink is too small, high temperature will accumulate inside the light source, while the lamp beads work under high temperature for a long time, the light decay is very fast, and the service life is also very long. Therefore, when choosing an LED downlight, it is recommended that you choose a 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 the LED downlight.
LED downlight purchase point 2: drive power.
The driving power supply is also called a transformer. The quality of the transformer also determines the life of the whole lamp. There is no problem with the lamp beads 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 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, which can ensure The output current and voltage are stable, thereby ensuring the safety and stable performance of the LED downlight during use.
LED downlight purchase point 3: lamp bead quality.
In addition to considering the material and driving power supply of LED downlights, the key point is to consider the quality of the lamp beads. The quality of the lamp beads determines the lighting effect of the lamp, and the packaging process affects key factors such as the quality of the lamp beads and heat dissipation. At present, there are domestic and imported LED chip chips on the market. Generally, different brands have large price differences and different lighting effects. It is recommended that you buy them carefully.
Under normal circumstances, downlights are used for general lighting, which requires ambient light. Downlight means a lamp with the light pointing downwards. Spotlights are used to provide local lighting, which requires local range light for close-up lighting, increasing light to protrude an object or part of an object (commonly there are shopping malls, clothing stores, mobile phone stores, etc.). Generally, when many homes are renovated, small-sized downlights are used in the living room. They are generally used as wall washers to increase the luminosity of the living room wall, corridors or aisle balconies, etc. Downlights are used for general lighting.
