Abstract

The utility model discloses a high heat conduction and highly insulated fluorescent lamp which comprises a lampshade, a radiator and a choke plug. A boss is arranged on the lampshade. And a groove buckled with the boss is arranged on the radiator. A cavity is formed by buckling the lampshade with the radiator, and ends of the lampshade and the radiator are fixed by the choke plug. Mains input plug pins are arranged on the choke plug. The high heat conduction and highly insulated fluorescent lamp is characterized in that a printed circuit board (PCB) is arranged in the cavity. Light-emitting diode (LED) lamps are neatly arranged on the front of the PCB provided with a drive circuit. A heat conduction silica gel belt is connected on the back PCB in sticky mode. The other face of the silica gel belt is connected with the radiator in sticky mode. One ends of the mains input plug pins stretch into the choke plug and are connected with inputs end of the drive circuit. The other ends of mains input plug pins stretch out of the choke plug and are connected with an external power supply. The utility model belongs to the field of LED tubes. The heat conduction silica gel belt is arranged between the back of the PCB and the radiator in sticky mode. The high heat conduction and highly insulated fluorescent lamp has the advantages of being high in heat conduction, high in insulation, convenient to assemble and reliable in electrical safety due to the high heat conduction and high insulation silica gel belt.

Description

The LED fluorescent lamp of the high insulation of high heat conduction

Technical field

The utility model relates to a kind of LED fluorescent tube field, the LED fluorescent lamp of the high insulation of particularly high heat conduction.

Background technology

At present, LED is high because of luminous efficiency, energy saving; Life-span length, adjustable brightness, advantage such as safe and reliable are applied among the lamp lighting widely, because LED is a heat-sensitive device, the quality of heat radiation, heat conduction and insulation directly affects the photochromic stability of fluorescent tube; If the heat that uses simultaneously the LED lamp work of hundreds of to send will soften circuit board, for example: the patent No.: 20102067288.7, name is called the LED fluorescent tube; It comprises lampshade, lamp body and heat-dissipating casing, on the radiator shell, is provided with substrate, forms cavity through fastening between lampshade and the heat-dissipating casing; In cavity, be provided with and comprise led light source assembly and LED driven unit, and the led light source assembly is located on the substrate, through LED driven unit driving LED light source assembly; Though good heat-radiation effect has been played in this design; But because on the directly fixing substrate with the radiator shell of led light source assembly, the cause of so in use generating heat simultaneously owing to a plurality of LED can be softened circuit board and do not have a good insulation effect; Well heat conduction simultaneously makes device in use dangerous.

Summary of the invention

The purpose of the utility model be provide for the deficiency that solves above-mentioned prior art a kind of high heat conduction, high insulation, easy to assembly, effectively ensure the LED fluorescent lamp of the high insulation of high heat conduction of electrical safety.

To achieve these goals, the LED fluorescent lamp of the high insulation of high heat conduction that the utility model designed comprises lampshade, radiator and plug; On lampshade, be provided with boss, the groove that on radiator, is provided with substrate and is interlocked, lampshade and the radiator formation cavity that is interlocked with boss; And the two ends of lampshade and radiator are fixed through plug, on plug, are provided with the power supply input pin, in cavity, are provided with pcb board; The positive proper alignment of pcb board has the LED lamp, on pcb board, is provided with drive circuit, and the back side gluing of pcb board has the thermal conductive silicon adhesive tape; And the another side gluing of thermal conductive silicon adhesive tape is on the substrate of radiator; For power supply signal is provided, power supply input pin one end stretches into plug and is connected with the drive circuit input, and the other end stretches out plug and links to each other with external power supply.

In order to play effective thermolysis, the outer surface of radiator is provided with fin.

The LED fluorescent lamp of the high insulation of high heat conduction that the utility model obtains; Through gluing between the back side of pcb board and fin the thermal conductive silicon adhesive tape is arranged; Because the thermal conductive silicon adhesive tape has high-termal conductivity, high-insulativity, thus realized high heat conduction, high insulation, easy to assembly, effectively ensure the advantage of electrical safety.
