<P>PROBLEM TO BE SOLVED: To solve a problem that a lighting shade for an incandescent electric bulb is not suitable for an LED electric bulb due to a going-straight property being characteristics of the light of the LED electric bulb and the structure of the LED electric bulb (irradiation at 180°, while the incandescent electric bulb irradiates in all directions at 360°), and it cannot improve the illumination intensity of the LED electric bulb. <P>SOLUTION: The reflecting shade with a conical shape can increase the total amount of luminous flux (lumen) on an irradiation surface since the reflecting shade makes the going-straight light of the LED electric bulb condensed and reflected on the irradiation surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
