LED (light emitting diode) illumination device with non-isolated type power supply and LED lamp

Abstract

An LED lighting apparatus and an LED lamp with a non-isolated power supply (11) comprise the non-isolated power supply (11) and an LED lamp bead (12) that is electrically connected to the non-isolated power supply (11). The LED lamp bead (12) is fixed on a bakelite PCB (13). A printed circuit (131) used for electrically connecting the LED lamp bead (12) to the non-isolated power supply (11) is arranged on one side of the bakelite PCB (13). The other side of the bakelite PCB (13) is welded with an radiator (14). A soldering paste layer (15) is arranged between the bakelite PCB (13) and the radiator (14). The LED lighting apparatus and the LED lamp have a direct heat dissipation effect, a structure volume of the LED lamp is reduced at the same time, the non-isolated power supply (11) can be adopted due to an insulation effect of the bakelite PCB (13), heat dissipation sources are reduced, power is improved by 50-80%, luminous efficiency is improved by 20-50%, and luminous flux is improved by 80-200%.

Description

technical field [0001] The present invention relates to an LED lighting device, more specifically to an LED lighting device and an LED lamp with a non-isolated power supply. Background technique [0002] In the prior art, in the LED lighting industry, heat dissipation is a technical problem. At present, most LED lamps use metal PCB boards as the carrier of LED lamp beads. Since metal PCB boards are conductive materials, when no insulating layer or other insulating structures are used between the metal PCB board and the housing of the lamps, LED lamps The input terminal of the power supply needs to adopt an isolated power supply structure with a transformer. Due to the isolated power supply structure with a transformer, the heat generation is large. When the LED lamp adopts an integral structure, the isolated power supply is often accommodated in the lamp housing and integrated with the radiator. Or it is set very close; thus, the isolated power supply becomes another heat s...

Problems solved by technology

At present, most LED lamps use metal PCB boards as the carrier of LED lamp beads. Since metal PCB boards are conductive materials, when no insulating layer or other insulating structures are used between the metal PCB board and the housing of the lamps, LED lamps The input terminal of the power supply needs to adopt an isolated power supply structure with a transformer. Due to the isolated power supply structure of the transformer, the heat generation is large. When the LED lamp adopts an integral structure, the isolated power supply is often accommodated in the lamp housing and integrated with the radiator. Or set it very close; thus, the isolated power supply becomes another heat source for LED lamps; this brings new technical problems to LED lamps that originally needed to solve the problem of heat dissipation
