led fluorescent lamp with reflector
I encountered such a problem when I was doing an energy-saving renovation project before. In a clothing factory, the original lamp used three primary color t5 fluorescent lamps, Philips, a row of double tubes, the illumination of the work surface is almost 850-900lx, the same height and arrangement. , replaced our LED fluorescent lamp 15w, the illuminance of the work surface is only about 550, of course, this illuminance can not meet the requirements of the other party, carefully analyzed the reason, it turned out that the t5 lamp they used, the quality is better, it is also a new lamp, light effect It is relatively high, and there is a reflector, so that the illumination of the work surface is relatively high. Finally, we tried to process a reflector with German An aluminum (material reflectivity of 85%). The illumination of the work surface has been improved, roughly in A little more than 700lx, the improvement rate is about 35% (later we can improve it by 40% through repeated improvement).
Therefore, in general, t8 and t5 are 360 light-emitting, and the use of high-efficiency reflectors can greatly improve the efficiency of the light source, while LED fluorescent lamps generally have a light-emitting angle of about 120 degrees. Whether it is possible to use high-efficiency reflectors to improve the efficiency of light source use through secondary light distribution (about 40%), the cost of a single-lamp reflector is about 40 yuan, and the cost of a double-lamp reflector is about 50 yuan.
The answer is no, not worth it. In this case, it is only effective to increase the power of the LED tube. After all, the LED fluorescent lamp only emits half of the light, and it does not make much sense to have a reflector. www.ledlongtech.com
At the same time, the overall lighting effect is improved, and the illuminance value increases faster. How to improve it?
Method 1, increase the power, pay attention to protect the LED lamp beads, consider the maximum current of the lamp beads, can not use all, there must be room, otherwise it will affect the service life of the lamp beads
The second method is to improve the light transmittance. The light transmittance of the pc cover can be improved. However, if it is too high, it may affect the aesthetics, and you will see led lamp beads, and the light expansion ability will decrease.
The third method is to change the light string, which is to increase the number of LED lamp beads, but it must be well designed. After all, after the increase of LED lamp beads, the cost of the whole lamp will increase faster.
Method 4. Using non-isolated power supply, high conversion efficiency, low cost, more cost-effective
Combining the above four points, it is ideal to make LED lamps with high luminous efficiency of 100-160lm/w
