Title:
INJECTION MOLDING HYPERBOLOID REFLECTOR AND INJECTION MOLDING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/215413
Kind Code:
A1
Abstract:
Disclosed are an injection molding hyperboloid reflector and an injection molding method therefor. The injection molding hyperboloid reflector comprises a pedestal (10) which is obtained by employing an injection molding process and which has a hyperboloid concave surface (101), and a reflecting layer (20) connected to the concave surface (101) of the pedestal (10). The pedestal (10) is an integral unit obtained by means of injection molding. The reflecting layer (20) is connected to the concave surface (101) of the pedestal (10) by means of the vacuum coating technology. The pedestal having the hyperboloid concave surface, which is obtained by means of injection molding, has good formability, is easy to install and transport, and facilitates the protection the reflective layer during a transportation process. The pedestal preferably adopts an engineering plastic capable of injection molding, thus has great weatherability and is resistant to deformation, thereby ensuring the service life of the hyperboloid reflector while also being light-weight. Meanwhile, the tolerance between the dimension specification of the hyperboloid concave surface of the hyperboloid reflector and the dimension specification of a theoretically calculated curved surface is small, and the hyperboloid concave surface is almost identical to the designed curved surface, which has excellent light focusing effects, and can improve the light utilization rate. The injection molding process is easily operable.
