[Wen Wei Liu Hai] "In the COB light source, we have done the most complete in the industry, COB manufacturers are looking for optical accessories basically find Dalco." Zhongshan Dalco Optical Co., Ltd. (hereinafter referred to as "Dalco" "General Manager Mr. Xiong Dazhang said to the Gaogong LED reporter.
As a supplier of LED optical solutions, Dalco specializes in the research and development of optical lenses, LED reflectors, optical plastic parts, optical molds, precision plastic molds and other products. As a high-precision optical component, the lens is one of the indispensable accessories for LED light sources and lamps. Its importance is self-evident, and the market demand is also relatively large.
In LED applications, the primary role of the lens is to perform a secondary optical design of the light intensity distribution of the LED source. It is understood that the materials currently used in the lens are mainly silica gel, PMMA (acrylic), PC (polycarbonate), glass, and each has its own advantages and disadvantages. However, in the field of LEDs, PMMA and PC are still the mainstays. PC has better heat resistance and is widely used in outdoor applications such as LED street lights. Acrylic heat resistance is slightly poor, so it is generally used indoors.
When talking about the company's sales performance, Xiong Dazhang said that he had done more than 30 million results last year, and this year's target is 60 million. “Darco has developed very fast in recent years, and its performance has increased 20 times in less than four years.†It is reported that Dalco’s sales in the first half of this year have doubled compared with the same period last year. At present, the company's performance is very prosperous, and the market demand is strong. The main bottleneck restricting the development of Dalco is that the company's production capacity is not enough, and it is necessary to expand the production scale to meet the market needs.
The most critical parameter of the lens is the angle of illumination. In addition, parameters such as brightness, spot illumination, and uniformity need to be considered in the design.
Xiong Dazhang said that at present, the technical difficulty of lenses and reflectors lies in the concentration of small angles. In combination with the actual situation of enterprises and industries, Dalco will adhere to the market-oriented and technological innovation as a means to develop new products that meet market needs and provide optical support for lighting customers.
These are the motors of Vacuum Cleaner. In the motors,there are some different styles. But they have a common point that is new type energy saving. This characteristic let vacuum cleaner is more easily use. These motors are all having rated voltage from 100V to 240V. They are all having rated power that is from 200W to 2000W. The rated voltage and rated power will change by different styles. Their rated frequency are all 50HZ or 60HZ. Their motors' total length, insulation grade,maximum vacuum degree and maximum quantity of wind will change by different kinds of motors. Now please see some pictures of motors blow.
