Embodiment Construction

[0050] Figure 2A A light emitting device 20 according to one embodiment of the present invention is shown. The light emitting device 20 includes an optical member 21 , a base 22 , and a longitudinal axis 24 . An optical member 21 such as a lens is connected to the base 22 to guide light entering therein. The longitudinal axis 24 may or may not pass through the center of the optical member 21 . The longitudinal axis 24 is preferably substantially perpendicular to the horizontal surface of the base 22 .

[0051] Figure 2B for Figure 2A A cross-sectional view of the light-emitting device 20. The illuminant 23 is disposed on a surface of the base 22 . The illuminant 23 includes (but not limited to) LED die, incandescent lamp, fluorescent lamp, cold cathode fluorescent lamp (CCFL), and other devices capable of emitting light and connected to the optical member 21 .

[0052] Optical member 21 may be a separate piece and may be attached to base 22 by a variety of means incl...

Abstract

This invention discloses a luminous device including an optical component, a base and an illuminator, in which, the optical component is used in leading the light mostly coming from the illuminator towards the longitudinal shaft direction vertical to the component and includes a horn part and a base part, the horn part includes an upper surface forming a notch, a side surface connected with the upper surface and in a curve state and a lower surface connected to the base. In another mode, convex lens is formed on the upper surface.

Description

technical field [0001] The present invention relates to a light emitting device, and more particularly to a light emitting body coupled to an optical lens that directs light rays substantially perpendicular to a longitudinal axis passing through a horizontal surface of the light emitting device. Background technique [0002] figure 1 Shown is a conventional light emitting diode (Light Emitting Diode; LED) package 10 , which includes an optical lens 11 , a package base 12 , and an LED die 13 . The LED package 10 has a longitudinal axis 15 passing through the center of the optical lens 11 . The LED die 13 is disposed on the packaging base 12 . The package base 12 may have a bowl (not shown), and the bowl may also have a reflector (not shown) to reflect light emitted from the bottom and sides of the LED die 13 toward the viewer. [0003] The optical lens 11 is connected to the LED die 13 to receive and guide light from the LED die 13 . The optical lens 11 has a cavity 14 fo...
