Can be color calibration equipment can improve the quality of LED lighting lamps and lanterns

With the continuous development of LED encapsulation, control integration technology, LED lighting products have appeared in the market. According to data released by the National Bureau of Statistics, in the next few years, lighting market share will continue to improve, according to the lighting accounted for about 10%, according to lighting lamps and lanterns of the nation's annual demand is about 50 million light, great lighting market stimulates the adjustable light color LED lights market, and presents the trend of the intelligent. Yet the light of the existing LED intelligent lighting products quality good and bad are intermingled. In terms of the characteristics of the chip, because the production process are identical, the same batch, the same kind of models of different parameters such as photosynthetic efficiency of the LED chip, light color is not the same. In terms of the lamps and lanterns, drive and the characteristics of the power supply device is different and the characteristics of the lamp shade is also influential to the optical characteristics of identity. Most manufacturers are still ignore the identity problem, but there is also a part of the pursuit of quality manufacturers through the adoption of identity good chip, narrow the scope of the drive power components, and take consistent lampshade materials to ensure the identity of the product. This approach, however, raise the cost of the lamps and lanterns! For to have the lamps and lanterns of different color channel, the color of the single channel consistency can be scaling multi-channel drive parameters to compensate for. At present, some lamps and lanterns manufacturer using artificial calibration ways to solve this problem. However, manual calibration method is time-consuming, laborious and because the artificial visual error, in this way is very difficult to guarantee the precision of the light color identity. In order to solve this problem, the state key laboratory of semiconductor lighting joint innovation developed an automatic calibration can be under arbitrary reference color lamps and lanterns to drive the parameters of the equipment. Through the device can automatically obtain the color of lamps and lanterns drive parameters. Through the test, after the equipment selection of lamps and lanterns can achieve high accuracy, light color identity of guarantee given under the condition of the same reference color coordinate, color difference between different bulbs cannot be identified by the human eye, i. e. color Du 'v' 0 or less. 006. In addition, using the automatic calibration equipment, scaling a light color palette of lamps and lanterns to only need less than 2 minutes. Use the equipment to calibration can be color lamps and lanterns, can reduce the BOM cost of manufacturer, allows manufacturers to choose in not high consistency of components under the premise of guarantee the consistency of different lamps and lanterns out light, greatly improve the quality of intelligent product of LED light color, and to avoid the defects of the artificial selection time-consuming to reduce the labor costs.
