The Advantages and Disadvantages of 5050 Lamp Beads, What Are the Calculation Methods for Light Flux

5050 lamp beads are common in our lives. LEDs are made of non -toxic materials. Unlike mercury in fluorescent lamps, it can cause pollution. At the same time, LED lamp beads can also be recycled. Let me briefly introduce the advantages and disadvantages of 5050 lamp beads and the calculation of the optical flux. 1. There are disadvantages of 5050 lamp beads. Advantages: 1. The white coordinate point is determined by the fluorescent powder itself, which has nothing to do with the inspiration chip (can tolerate the discreteness of the LED chip). 2. It can achieve extremely high color restore index RI. 3. In theory, it is the simplest manufacturing solution. 4. The stability of the color light depends only on the fluorescent powder, which can be very stable. Disadvantages 1. The leaked ultraviolet light will destroy LED sealing, causing the life of the device. 2. The light conversion efficiency is not high, the self -absorption, light transmission rate, etc. 2. The calculation method of 5050 lighting light flux 1. LED lamp bead light flux LED lamp beads light flux is mainly used in the equal distance configuration of the LED lamp space. In the space where restaurants, restaurants, houses, etc. need to improve the atmosphere, in order to confirm the approximate illness, it is convenient to use this LED illuminance calculation method. 2. LED lamp beads one by one computing algorithm illumination of the calculation algorithm is used when calculating the actual degree required for local lighting and the key display part. When LED Lighting Delite Calculation Calculation Example 1 Install a 500lm 100W nude bulb, assume that 30%of the light beam should be directly illuminated on the ground, so how much is the direct illumination of the ground on the ground? E = f/a = 1500*0.3/10 = 45LX Except for the beams that are illuminated on the ground, other beams illuminate the ceiling and wall. If the reflectance of the ceiling and the wall is high, the reflection light will be added to the direct illumination of the ground, so the actual illumination is above 45LX or more. Most of the lamps for the basic LED lighting are direct light -equipped down light lighting and mixed lighting lamps of fluorescence lamps, as well as indirect lighting of ceiling tanks such as light glow slots. The illustration of the direct light with light, the more the top is the ceiling. The impact of the wall reflectance rate is less. Even if the setting of the room's reflectance is somewhat different, the average illumination error will be very small. However, if there are high partition walls and furniture, the calculation results of the shadow part are deviated from. In addition, the indirect LED lighting of the ceiling must not only be affected by the ceiling surface, but also greatly affected the wall reflectance rate. When the distance from the ceiling is different, the lighting utilization rate will change, so it is difficult to achieve low calculation. The above is the advantages and disadvantages of 5050 lamp beads. What are the simple introductions of the optical flux calculation method?.
