First, look at the shell: to see what material is made, the gap between aluminum and plastic is very large.
Second, look at the driving power of the lamps:
The quality of the drive power also determines the life of the whole lamp. It is no problem to use the lamp for more than 50,000 hours, but if the drive power is broken, the whole lamp will not shine. The electronic components and design scheme used in the driving power supply determine the efficiency, power factor, stability, temperature rise value and service life of the driving power supply. If the user does not understand the component knowledge, it can be judged from the size and weight of the transformer and the electrolytic capacitor used by the manufacturer. The difference in the price of LED ceiling lamps, the quality of the drive power is the core of the entire LED, so the price is not a small proportion.
Third, understand the brand and packaging of the lamp beads:
The quality of the lamp bead determines the lighting effect of the LED ceiling light, and the packaging process affects the key factors such as the quality of the lamp bead and heat dissipation. Lamp beads chips include US chips, Taiwan chips, and domestic chips. Different brands have different price differences and different lighting effects.
Users can learn about the lamp bead solution by consulting the manufacturer, depending on the integrity of the manufacturer. The ceiling lamps with extremely low prices are often produced using the defective products produced by the chip production line. The color temperature is inconsistent, the brightness is poor, and the life is short. Users need to pay attention.
Fourth, look at the brightness, LED lamps in addition to brightness, light color stability is also an important indicator to judge the quality of LED. There is a way to check the light color of the LED lamp. After the lamp cup is lit, put a piece of white paper on the head of the lamp cup at a distance of 5 cm. (Because the lens is refracted, the white paper should not be close to the lamp cup. The better quality LED light cups have better light color consistency, while the inferior LED light cups just produce different color areas. This method can be observed by the naked eye.
Conditional friends can try it. There is currently no good solution for the color instability of LEDs, but it is clear that the color deviation of single-money chips is much more serious than that of double-gold chips.
ONEREEL`S INJECTION MOULDED PLASTIC YARN CARRIER DYE TUBES / DYE CONES FOR YARN STEAMING & DYEING, BOBBINS, RING SPINNING TUBES & OTHER PLASTIC PARTS IN VARIOUS POLYMERS AND ALSO STAINLESS STEEL DYEING MACHINES ACCESSORIES
ONEREEL have specialized in the production of Plastic/Polymers mold and Tool making for the Textile & associated industries for over 35 years. The development in winding technology, Yarn package formation and the Yarn Dyeing equipment have led to greater utilisation and productivity and at the same time improved the quality of the yarns and their running properties. The Dye packages and Tubes are most important for an optimum Dyeing Cycle. The main features of an optimum Dye package are :
Conicity
Winding Technique
Package Face
Package Edges and Tubes
Under the trade name 'ONEREEL', marketing permeable Cylindrical Tubes and Cones for Yarn Dyeing. An important advantage of Cylindrical Packages or Cheeses is that the liquor flow is effected symmetrically towards the center line of the package. Above all, the liquor flow is more favorable when dye tubes with a large diameter are used. The tubes from 'ONEREEL' permit the same uniform flow throughout the package. Moreover, a better utilization of the volume is achieved than with cones replacing conventional cones with cheeses, guarantees an optimal levelness of Dyeing and offers significant advantages from an economic point of view.
'ONEREEL' ADVANCE PRODUCTS TO REDUCE COSTS.
'ONEREEL' product range having variety of items intended for every stage of yarn production, preparation for Spinning (Ring, Open-end, Self acting), Twisting, Winding and Package Dyeing.
'ONEREEL' product range has been improved since few years with highly innovative and patented Yarn carriers in order to satisfy the necessities of the Package Dye sector especially which is under high development. The Policy of all new systems is the research to match the best Dyeing result with the easiest method to use yarn carriers; means to reach the following results that only the right Yarn Carrier can guarantee.
