Embodiment Construction

[0058] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0059] In related technologies, light-emitting diodes (LEDs) have a relatively large light-emitting area. On the premise that the light-emitting brightness is determined, the current required to drive the LED to emit light has also been determined. A large light-emitting area will inevitably lead to a small current density. When the LED works at a low current density, the luminous efficiency of ...
