Abstract
The utility model discloses an LED bulb lamp and relates to the field of lighting lamps. The LED bulb lamp comprises a lamp holder which is in threaded connection with a lamp base, a drive circuit board, an LED light source electrically connected with the drive circuit board, a radiator connected to the bottom of the lamp holder and a lamp shell connected to the bottom of the radiator. The LED light source comprises an aluminum substrate and an LED lamp bead which is connected with the aluminum substrate through a crystal solidifying layer. The radiator comprises an outer radiating hood and an inner radiating hood. A circular radiating sheet is connected to the periphery of the bottom of the inner radiating hood. The periphery of the bottom of the outer radiating hood is connected with the round aluminum substrate in a sealed mode so that the radiating sheet of the inner radiating hood and the aluminum substrate of the outer radiating hood form a cavity in between which is filled with liquid with the high heat transmission rate. According to the LED bulb lamp, liquid with the high heat transmission rate such as transformer oil is used for replacing heat transmission silica gel in an existing LED bulb lamp, the heat transmission efficiency of the LED light source is greatly improved and the service life of an LED lamp is prolonged.
Description
Technical field
The utility model relates to field of illuminating lamps, the LED bulb lamp that particularly a kind of radiating efficiency is high.
Background technology
LED is a kind of solid-state semiconductor devices that can be visible ray by electric energy conversion, and it can be directly light electric energy conversion.Because long service life, the energy consumption of LED lamp is low, it is remarkable to save the energy, therefore LED lamp is widely used in daily life as light source, and LED bulb lamp is the one in LED lighting.The structure of LED bulb lamp comprises lamp housing, LED light source, radiator, drive circuit board and lamp holder, its core luminous component is LED chip, in work, LED chip can produce high heat, drains not in time heat, will impact the service life of LED chip.The heat passage of known LED bulb lamp is LED chip-die bond layer-substrate-heat-conducting glue-radiator-air, analyze each link in known system and can produce certain influence to the thermal resistance of whole LED system, the weakest link of at present LED bulb lamp heat radiation is not radiator but heat transmission between heat-conducting substrate and radiator, this is because the thermal conductivity factor of silicon heat-conducting glue is too poor, can not in time the heat of LED lamp pearl be passed to radiator, LED lamp pearl will produce serious heat build-up, causes light decay and even the inefficacy of LED lamp pearl.
Utility model content
The purpose of this utility model is to provide a kind of LED bulb lamp, the heat-conducting medium overcoming between existing LED bulb lamp heat-conducting substrate and radiator can not pass to radiator by the heat of LED lamp pearl in time, can produce serious heat build-up, the defect that causes LED lamp pearly-lustre to decline and even lost efficacy, provides a kind of and the heat of LED lamp pearl can have been passed in time to radiator, LED bulb lamp that radiating efficiency is high.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: a kind of LED bulb lamp, comprise the lamp holder being spirally connected with lamp socket, drive circuit board, the LED light source being electrically connected with drive circuit board, be connected in the radiator of lamp holder bottom and be connected in the lamp housing of radiator bottom, described LED light source comprises aluminium base and the LED lamp pearl being connected with aluminium base by die bond layer, described radiator comprises outer heat dissipating housing and interior heat dissipating housing, the circumference of described interior heat dissipating housing bottom connects a circular heatsink, thereby the circumference of described outer heat dissipating housing bottom is connected between interior heat dissipating housing-fin and outer heat dissipating housing-aluminium base and forms cavity with circular aluminum base plate seals, in described cavity, fill the liquid of high thermal conductivity.
Described outer heat dissipating housing outer surface outwardly convex forms heat radiation fin.
The liquid side of the being canopy oil of described high thermal conductivity.
Compared with prior art, the utlity model has following advantage: the liquid of the side's of employing canopy wet goods high thermal conductivity replaces the heat conductive silica gel in existing LED bulb lamp, the heat that LED lamp pearl produces is sent to radiator fast by the heat-conducting liquid of being located in its back cavity, through the thermolysis of radiator, increased substantially the heat transfer efficiency of LED light source.
