LED ceiling light technical characteristics how to choose LED ceiling light

Introduction: LED ceiling light is a new type of ceiling lamp designed and manufactured by aluminum alloy with high thermal conductivity and patented structure technology. LED ceiling lights are widely used in commercial lighting, and the field of home lighting is slowly infiltrating. Here is a brief introduction to the technical characteristics of the LED ceiling light and how to choose the LED ceiling light.

Technical characteristics of LED ceiling light:

LED ceiling light use light source: All energy-saving and environmentally-friendly low-light decay LEDs are used as light sources to ensure long life, energy saving, high efficiency and environmental protection.

LED ceiling light protection level: Level II

LED ceiling light power supply type: generally use external power supply

LED ceiling light distribution: narrow light (15 ° 30 °) wide light (45 ° 60 ° 90 °) optional, mainly related to the angle of the selected lens

LED ceiling light wiring: terminal wiring

LED ceiling lights are installed at indoor and high-end locations.

How to choose LED ceiling light:

The choice of LED ceiling light is mainly considered from the following three aspects:

1. Look at the radiator used in the luminaire:

The speed of heat dissipation of the lamp determines the degree of light decay and the service life of the whole lamp. The lamp beads work under high temperature for a long time, the light decays quickly, the life is very short, and the ceiling lamp with too bad brightness can not achieve the effect of accent lighting.

LED ceiling lamp radiator solution, the mainstream has an integrated radiator method, a single lamp bead, a cooling column method, and an external fan cooling method.

The size of the heat sink and the quality of the aluminum material affect the speed of heat dissipation and also affect the price of the entire LED ceiling light.

2, look at the power of the lamps (commonly known as the transformer): the quality of the transformer also determines the life of the LED ceiling light, the lamp is used for more than 50,000 hours no problem, but if the transformer is broken, the LED ceiling light 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.

If the user does not understand the component knowledge, it can be judged from the size and weight of the transformer and the electrolytic capacitor used by the manufacturer. The difference in the price of LED ceiling lamps, the quality of transformers accounts for a large proportion.

3. Understand the brand and packaging of the lamp beads:

The quality of the lamp bead determines the lighting effect of the LED ceiling light, and the packaging process affects the key factors such as the quality of the lamp bead and heat dissipation. Lamp beads chips include US chips, Taiwan chips, and domestic chips. Different brands have different price differences and different lighting effects.

Users can learn about the lamp bead solution by consulting the manufacturer, depending on the integrity of the manufacturer. The ceiling lamps with extremely low prices are often produced using the defective products produced by the chip production line. The color temperature is inconsistent, the brightness is poor, and the life is short. Users need to pay attention.
