LED light specifications:
1. According to the lamp holder: e27 e14 b22
2. According to the power: 2W 3W 5W 7W 9W 11W (11W is only seen in Yedian Lighting)
3. According to the light color: white light, warm white
4. According to the shell material: aluminum alloy, plastic, ceramic
Main parameters of LED lights:
1. Color temperature: conventional color temperature: warm white light (WW) 2700-3200k, natural light (NW) 4000-4500K, positive white light (PW) 6000-6500K, cool white light (CW) 7000-7500k.
In addition, single colored lamp beads such as red, green and blue can also be used.
2. Power: The general power of LED bulbs is below 12W. Common LED bulb power is divided into: 3w, 4w, 5w, 6w, 7w, 8w, 9w, 10w.
3. Voltage and current: Voltage and current are also very important basic parameters of LED bulbs.
The grid voltage of different countries in the world and the voltage used in some occasions are different. Commonly used voltages are 12v, 110v, 220v, 85v-265v.
4. Light efficiency: Light efficiency is also a very important factor for LED bulbs.
5. Luminous flux: The luminous flux is mainly determined by the luminous efficiency and power of the LED bulb. It is generally measured with an integrating sphere.
6. Illuminance: The unit of illuminance is lux, which is Lux in English, and can also be abbreviated as Lx now.
The illuminance produced by 1 Lm of luminous flux evenly distributed on a 1 square meter surface. Illuminance is usually measured with an illuminance meter. The illuminance meter is simple to use and inexpensive to purchase. When there is no integrating sphere system, the illuminance meter can be used as a reference.
7. Light decay: Light decay, in popular terms, is how much the brightness of the bulb decreases after a certain period of use. The main factors affecting the decay of LED lights are heat dissipation and current. The current is unstable, the heat dissipation effect is poor, and the light decay will be very serious.
8. Color difference: Color difference is the inconsistency of color temperature. Generally, warm white light (2700-3200k) will consider the color difference.
9. Color rendering: The degree to which the light source presents the color of the object itself is called color rendering, that is, the degree of color fidelity.
10. Glare: There are objects with extremely high brightness or strong brightness contrast in the field of vision, which can cause visual discomfort called glare. Glare is an important factor affecting the quality of lighting.
11. Service life: LEDs can be used for more than 50,000 hours in general instructions, and some manufacturers claim that their LEDs can operate for about 100,000 hours.
