LED industry has recently been rapid development in the world, especially the decorative lighting is in full swing, widely used in the floor, body contour, bridges, squares and other municipal lighting projects, as well as hotel, KTV, the hotels, playgrounds and other places of entertainment . LED lighting products (t5 led fluorescent tube) main components: LED light emitting diode, PCB circuit board, housing. These materials constitute the main body of lighting products, the basic decisions of the material quality of lighting products.
Following the selection of the three materials do a brief description of the impact of lighting products.
1, LED Lights Emitting Diode
The brightness of the light emitting diode is determined by the brightness of the LED chip and light body package outline, its life is determined by the working environment and quality of the LED chip. Special note here is that the LED chip LED lighting products (t5 led fluorescent tube) used in the standard sizes are generally as follows: red, yellow, 12mil, blue, green 14mil, but also useful for 8-10 mil chip. Different sizes of chip brightness, but their life is completely different, because the unit area of chip over power the greater the shorter its life, which is the same brightness light-emitting diodes price is not the same reason.
2, the PCB board
Direct impact on the circuit board as the carrier of the light source lamp life and failure rate. LED lighting products, electronic circuit on the PCB, its material and processing technology will directly affect the product quality and life expectancy. Circuit board material is divided into a full glass, half glass, cardboard, three kinds. LED lighting products, standard materials should be full fiberglass panels, such as the use of semi-fiberglass or cardboard single panel post-weld quality and moisture, the ability of anti-aging and electrical will be greatly reduced.
3, Housing
Housing of LED Tube (t5 led fluorescent tube) as light mixing layer and the protective layer of lighting products, but also affect the effectiveness and life of the lamps. Now used in engineering plastics, general PC (polycarbonate), its anti-aging, anti-UV, the impact effect is best. Also useful for PMMA (acrylic), and its weather resistance a little bit weak and brittle fragile. The PC material is colorless and can be processed according to the need to add a different color agents of different colors of the PC tube. Commonly used PC tube is transparent and milky two. Transparent tube brightness than the milky, milky white color mixing is better than the transparent tube.
