Abstract

The invention discloses an LED luminescent device with an insulation protection apparatus. The LED luminescent device comprises an aluminum substrate and a luminescent portion arranged in the middle of the aluminum substrate. An LED luminescent chip is arranged in the luminescent portion, two sides of the luminescent portion are provided with surface-mounted electrodes which provide power for the luminescent portion, a condenser cover is arranged above the luminescent portion, and the insulation protection apparatus is arranged on the upper portion of the luminescent portion. The insulation protection device is in ring arrays formed by insulation columns, and the ring arrays encircle the condenser cover. According to the LED luminescent device with the insulation protection apparatus, the insulation protection apparatus arranged above the luminescent portion is used and is in the ring arrays formed by the insulation columns, and the ring arrays encircle the condenser cover, so that on one hand, the insulation columns can serve as limit apparatus to prevent lamp beads from being crushed, and on the other hand, the insulation columns can effectively resist impacts of large currents.

Description

technical field

[0001] The invention relates to a lighting device, more precisely, an LED light-emitting device with an insulating protection device. Background technique

[0002] LED is an abbreviation taken from the three words Light Emitting Diode, which translates as "light emitting diode" in Chinese. As the name suggests, a light emitting diode is an electronic device that can convert electrical energy into light energy and has the characteristics of a diode. Today's LED lamp beads, especially high-power ones, generally use patch electrodes. When a large current is passed through the electrodes, it is easy to cause electrode breakdown and cause a short circuit. In addition, when the LED lamp bead is installed, since there is no limiting device, the entire condenser cover is easily crushed, and even the LED chip is crushed.
