As an outdoor application, high-power LED lamps not only need to solve the problems of uniformity and brightness, but also have certain requirements in terms of light distribution, that is, the coverage area should be large enough, and the light can be stretched left and right. In this way, real-aware LED lighting can be realized. Combined with the current application status of LED high-power outdoor lighting, in 2012, its technology research and development will focus on the following aspects:
First, improve the light extraction efficiency and luminous flux, reduce the thermal resistance of the package, improve the secondary optical design, and improve the brightness of the LED light source;
Second, to strengthen the research and development of power systems, high-power LED lamps need constant current drive power, in order to ensure the constant output power of LED lamps, especially the current situation of unstable supply voltage supply in China, this point is more important;
Third, strengthen the research and development of LED chips, achieve core technology autonomy, and further reduce the cost of LED lighting.
950series Impeller And Diffuser
The guide wheel also includes the guide wheel; the guide wheel includes the guide wheel body and the accommodation space for the impeller; the one side of the guide wheel is equipped with a capacitive space; the guide wheel is set with several guide blades; several guide blades are arranged in the direction of the guide wheel in the direction of the guide wheel and two adjacent. The blade of the guide wheel is surrounded by the guide wheel as a guide runner; the outlet of the guide runner is arranged on the side of the guide body near the accommodation space and near the center of the body of the guide wheel; the inlet of the guide runner is set on the side wall of the guide wheel, and there are several impeller blades in the impeller; if the impeller blades are at the center of the impeller, the impeller is at the center of the impeller. The direction of the edge is set in the impeller; the adjacent impeller blades and the impeller are surrounded by the impeller flow path; the inlet of the impeller flow passage is set on the side of the impeller and is close to the center of the impeller; the impeller's exit is set on the side wall of the impeller; the impeller is set in the guide wheel, and the diversion groove is far away from the guide wheel; the entrance and guide of the impeller flow passage is made. The exit of the wheel is connected. Our company has become a supermarket for leaf guide and submersible pump parts at home and abroad.
