Materials & Character:        
- The semi-sphere shape lamp to make the reflection area reach the highest value added by an even curvature to have an even distribution of the rays without overlapping and shady areas.    
- Technology of anode oxidation with silicon dioxide coating film are adopted in manufacturing the lampshade, this will not only raise abilities of corrosion resistance and insulation power.    
- Structure of body-separation style is adopted so that the axial direction adjustment of the light bulb and lampshade in their corresponding position is made possible in order to meet demands for different degree of illumination.
