Abstract

The invention discloses a light source component which comprises a loader, a plurality of light emitting units, a plurality of first leads and a plurality of second leads, wherein, the light emitting units, the first leads and the second leads are configured on the loader respectively. In addition, all light emitting units are respectively and electrically connected with one of the second leads or one of the first leads. Therefore, the light source can provide a relatively even light source.

Description

technical field [0001] The present invention relates to a light source assembly and a method for adjusting brightness, and in particular relates to a light source assembly using a light emitting unit and a method for adjusting brightness. Background technique [0002] In recent years, light emitting diode (LED) devices using gallium nitride-containing compound semiconductors, such as gallium nitride (GaN), aluminum gallium nitride (AlGaN), indium gallium nitride (InGaN), etc., have attracted much attention. . Group III nitrides are materials with a wide band energy gap, and their emission wavelengths can cover from ultraviolet light to red light, so it can be said to almost cover the entire visible light band. In addition, compared with traditional light bulbs, light-emitting diodes have absolute advantages, such as small size, long life, low voltage / current drive, not easy to break, mercury-free (no pollution problem), and good luminous efficiency (power saving), etc., Th...
