LED lamps include landscape lamps and lighting lamps. There are two types of lighting fixtures: indoor lighting fixtures and outdoor lighting fixtures. Outdoor lighting fixtures are mainly LED street lights. Indoor lighting fixtures include LED ceiling lights, LED tube lights, LED downlights, LED flat lights, LED industrial lights, and other types. There are also some lamps that are actually variations of the above types. For example, LED corn lamps can be regarded as variants of LED bulbs.

From the perspective of consumers, it is recommended that when purchasing LED lighting fixtures, in addition to the price level, some major technical parameters of LED lights need to be understood. These parameters include power, input voltage, color temperature, lighting angle, lighting efficiency or luminous flux, color rendering index, and so on.

Power: refers to the total power consumption including the drive power, which determines the power consumption of the LED lamp.

Input voltage: refers to the voltage and type of the power grid to which the LED light can be directly connected, usually AC220V, and there is also direct DC power, which can be powered by a storage battery.

Color temperature: The temperature of the black body when the color of the light emitted by the light source is the same as the color of the radiant light of the black body at a certain temperature is called the color temperature of the light source. In popular terms, the color of the light. 3000K is equivalent to the light in summer sunset and 6000K is equivalent to Light at noon in winter. Runze Optoelectronics LED lighting products have 4 color temperature segments for customers to choose from.

Lighting angle: refers to the angle of the LED light line projection, which determines the illumination range of the LED light.

Luminous efficiency: The ratio of electric energy to light energy, usually obtained by dividing the luminous flux by the power. Luminous flux refers to the intensity of light radiation that the human eye can feel. The unit of luminous flux is lumens (LM), and the unit of luminous efficiency is LM / W.

Color rendering index: reflects the color rendering ability of light to objects. Generally, sunlight is used as the reference system. A color rendering index of 100 is considered equivalent to sunlight. Generally, it can meet the application when it reaches 70. Above 80 is excellent. The wider the spectrum contained, the higher the color rendering index.
