LED (Light-emitting Diode) bulb light

Abstract

The invention relates to lighting fittings, in particular to an LED (Light-emitting Diode) lighting fitting. An LED bulb light comprises a light holder piece, a metal radiating shell, a paraffin wax container, paraffin wax, a seal ring, an LED light bead array substrate, light guiding pillars, a light cover and an LED drive power supply circuit, wherein the metal radiating shell is in a cup-shaped container appearance; the paraffin wax container is arranged in the metal radiating shell; the paraffin wax is held in the paraffin wax container; the LED light bead array substrate is fixed on a support face of a fixed column of the light holder piece and can be contacted with an upper cover plate of the paraffin wax container; the LED drive power supply circuit is clamped in the light holder piece and is arranged in a cavity of the metal radiating shell; the LED light bead array substrate is formed in such a manner that a plurality of LED light beads are arrayed on a heat conducting substrate; a light guiding pillar is fixed on each LED light bead, and is formed by connecting a pillar body and a multi-surface rhombic body; a semi-perspective and semi-reflecting film system is plated on each rhombic face of the multi-surface rhombic body; and the light cover covers the metal radiating shell. The LED bulb light is applied in occasions needing to be lightened.

Description

technical field [0001] The invention relates to lighting fixtures, in particular to LED lighting fixtures. Background technique [0002] Due to the advantages of LED's excellent luminous efficiency and long service life, LED bulbs are new energy-saving lamps that replace traditional incandescent bulbs. The structure of LED bulb lamp generally includes LED substrate, heat dissipation shell, optical system and LED drive power circuit, etc. The LED drive power circuit provides working power for the LED substrate, and the heat on the LED substrate is transferred to the outside through the heat dissipation shell. The optical system will The optical path of the LED substrate is shaped and then output. [0003] Existing LED bulb lamps usually use relatively high-power LEDs to meet the needs of actual lighting. However, the calorific value of high-power LEDs must be relatively large. If the heat dissipation performance cannot be achieved well, it will have a great impact on the li...

AI Technical Summary

Problems solved by technology

However, the calorific value of high-power LED must be relatively large. If the heat dissipation performance cannot be achieved well, it will have a great impact on the light decay and life of the LED.

The existing LED bulb lamps are generally improved for the heat dissipation shell to improve the heat dissipation performance, but only the improvement of the heat dissipation shell can no longer meet the heat dissipation requirements of higher power LEDs.

On the other hand, due to the limitation of LED lamp beads, the existing LED bulb lamp has a single angle, which cannot achieve the 360-degree lighting effect of traditional lamps.
