Problems solved by technology

In the case of using a dimmer that controls the conduction time (on / off), basically the PN junction light-emitting element does not emit light when it is below 10V, and the light-emitting time is limited. If the communication time is limited, it will cause problems such as blinking

Abstract

The present disclosure discloses a lighting apparatus using a PN junction light-emitting element, the apparatus including: a power transmitting substrate having a plurality of boundaries defined thereon; a plurality of PN junction light-emitting elements positioned within each boundary and divided into a plurality of groups; and a first switch provided on the power transmitting substrate, wherein the first switch goes into the ON state by a supplied AC having a first voltage to cause PN junction light-emitting elements of a first group positioned within each boundary to emit light, and the first switch is in the OFF state when PN junction light-emitting elements of a second group, which is positioned within each boundary and connected in series to the first group, emit light by a supplied AC having a second voltage higher than the first voltage.

Description

technical field [0001] The invention relates to a PN junction light-emitting element lighting device, in particular to a PN junction light-emitting element lighting device with reduced volume and weight. Background technique [0002] The background art related to the present invention is described here, but the background art is not necessarily a known art (This section provides background information related to the present disclosure which is not necessarily prior art). [0003] Typically, in a PN junction light emitting device lighting device, a light emitting diode module in which a plurality of light emitting diodes (Light Emitting Diode) are mounted on a power transmission substrate is used as a light source. Light-emitting diodes have the advantages of small size, low power consumption, and excellent control characteristics, so that light-weight light-emitting diode lighting devices can be manufactured. However, a general LED lighting device requires a heat sink for h...
