Consistency of LED display screen is the most concern for all screen manufacturers. High-end LED screen manufacturers introduce point-by-point correction and color uniformity correction technology to compensate for the lack of consistency of LED lamps. Consistency The parameters such as brightness, wavelength, splitting ratio, eccentricity, consistency of the card point, light distribution, and viewing angle of the LED lamp are required to be strict. Therefore, the elliptical lamp package should be inserted in line with the brightness, wavelength, splitting ratio, viewing angle, and the same color.
The specifications of the elliptical LED tube, one of the core components of the high-end display, are demanding, such as the brightness, wavelength, light shape, RGB light distribution, attenuation, and failure rate of the tube.
The parameters such as light distribution, RGB light distribution, eccentricity, and card point consistency failure rate are indispensable. Stable process conditions and strict quality control systems ensure high quality products. Brightness: R>1000mcd, G>2000mcd, B>500mcd; Wavelength: 3nm bin; Spectral ratio: 1:1.1; Viewing angle: horizontal direction 105±5°, vertical direction 55±5°; Light distribution: relative light of the same color Strong light distribution curve is controlled within 10%, RGB relative light intensity distribution curve is controlled within 10%, and failure rate is less than three hundredths. To meet such requirements, we must ensure the quality and service life of LED displays. However, we must strictly control the source materials of LED displays to ensure the quality of LED lights in order to produce high-end LED displays.
HDPE Blowing Bottle is blowing by HDPE material only, this bottle likes more luxury and high quality package. It is only made by a blowing mold, no need preform. We can also supply mist pump, lotion pump, disc cap, flip cap together with the bottle. High quality control onsite is for keep the timing without delay. we also can do project design for client, such as drawing, graphic and mold creating.
