Many offices use LED panel lights for lighting. The advantage of this is that the luminous surface is wider, making full use of the light source, and the LED panel lights look beautiful, making the overall space effect look beautiful and temperamental. But we found a problem, that is, there are many factors that will affect the use of led panel lights, let’s take a look.
- LED chips
At present, the LED light sources generally used in LED lighting products on the market are roughly divided into low-power LED light sources, high-power LED light sources and integrated high-power LED light sources. Generally, the brightness of LED light sources on the market is roughly 100LM /W or so, but many LED panel light manufacturers generally set the operating current to be slightly lower in order to prolong the service life of LED lamps, which results in the measured brightness of LED panel lights for office lighting. Many are below 100LM/W; The maximum brightness of the light source lamp bead itself can be roughly 120LM/W.
- Light efficiency
Like some products made of high-power light sources, if the matching power supply efficiency is not high, plus the loss of the lampshade, the general light efficiency is only 30~60LM/W; The general luminous efficacy of the power supply and the products without the second concentrator of the frosted mask are roughly around 50LM; generally like the LED fluorescent lamp, it is generally 50-80 lumens, and if it exceeds 80 lumens, the power supply and the brightness level of the lamp bead itself are equipped. The higher it is, the more likely it will be.
- Power Factor
If the power factor of the LED panel light is low, it means that the driving power supply and circuit design are not good enough, which will affect the service life of the lamp; the second is the quality of the lamp, and the quality of the LED panel light for indoor lighting can be determined from the chip quality and packaging technology. It is reflected; again, it is the heat dissipation condition. The heat dissipation function of the LED panel light is very important. If the power factor and quality of the lamp bead are the same, the heat dissipation condition will have a great impact on the light decay, thereby affecting the life of the lamp; The last is power efficiency. In general, the higher the power efficiency of the lamps, the better. Because when the efficiency of the power supply is higher, the power consumption of the power supply itself is smaller and the output power is larger.
- Glare value
Glare is commonly referred to as “dazzling”, it can make people feel dazzling and cause eye soreness. If the flat panel lights is low value in glare performance, its lighting performance will be much better. The best led lighting manufacturers generally provide the good panel light with UGR<19, it is a standard in glare value performance.
Therefore, when customers choose which lamps to use, they must fully consider various use occasions, as well as their own needs, etc., and choose lamps according to their actual use conditions.
