Abstract
The utility model provides an outer shell heat-dispersion LED lamp, comprising an outer shell (1), a surface cover (5), an LED mounting plate (2), a plurality of high-power LEDs (3) and a power supply (4); the plurality of high-power LEDs (3) are fixed on the LED mounting plate (2); a plurality of high-power LEDs (3) are connected in series and in parallel to form an LED array so as to form a light source; the power supply (4) is electrically connected with the light source to provide electricity; the high-power LEDs (3) contact the LED mounting plate (2) in a thermal way; the LED mounting plate (2) transmits the heat produced by the high-power LEDs (3) to the outer shell (1) for dispersion. The utility model is simple in structure, is low in cooling cost and is good in cooling effects, and can greatly improve the power of LED lamp.
Description
Technical field
The utility model relates to a kind of with the LED lamp of shell as radiator.
Background technology
LED is used in producing and living widely owing to its luminous efficiency height, long service life, free of contamination advantage.Because each LED power is little, so the LED lamp holder is all combined by series-parallel system by tens of or hundreds of LED.If untimely the distributing of the heat that each LED produces will be reduced the light efficiency of LED, reduce the life-span of LED simultaneously in luminescence process.But, owing to the LED lamp radiating effect that existing power is bigger is poor, make high-power LED lamp short service life, power is restricted simultaneously.People are developmental research in this respect also, as the Chinese patent application publication number is the patent documentation of CN1277665A, disclosed a kind of LED lamp heat sink conception, this scheme is the heat that absorbs the pedestal that connects LED by the joint pin in the lamp body, still in lamp body, dispel the heat then, owing to be repeatedly to dispel the heat indirectly, and in the sealing lamp body, dispel the heat, so poor effect.In Chinese patent application publication number CN1359137A document, a kind of heat pipe lamp heat sink conception is disclosed, it is the heat that absorbs light-emitting device by super heat-conductive pipe one end, at the lamp body radiating piece of other end transfer of heat to the air contact, because it still takes indirect heat radiation, so radiating effect is not good, simultaneously, this radiating mode, complex structure, manufacturing cost height.
Summary of the invention
The purpose of this utility model just provides a kind of good heat dissipation effect, simple in structure, the low LED lamp of heat radiation cost.
A kind of shell radiating type LED lamp that the utility model proposes, it comprises shell, cover, LED installing plate, several great power LEDs and power supply, several great power LEDs are fixed on the LED installing plate, several great power LED connection in series-parallel connect the back and form led array formation light source, power supply is electrically connected power supply with light source, it is characterized in that described high-power LED metal base and the thermo-contact of LED installing plate, LED installing plate and shell thermo-contact, the heat dissipation channel of formation great power LED.
Adopt said structure, the heat that produces during the work of LED lamp, because high-power LED metal base and the thermo-contact of LED installing plate, LED installing plate and shell thermo-contact, the heat that is delivered on the LED installing plate by the high-power LED metal base will the overwhelming majority be delivered on the shell, whole casing has become the radiator of LED lamp, because the surface area of shell is bigger, heat will distribute by shell fast like this.
Power supply is fixed on the LED installing plate, and power supply base plate and the thermo-contact of LED installing plate form heat dissipation channel.Because the power of LED lamp is bigger, also produces bigger heat during power work, the power supply base plate is the metal heat-conducting material, and the heat that produces during power work by the power supply base plate is delivered to the LED installing plate and distributes by shell.
Shell and LED installing plate as radiator are to be made by the good material of heat conductivility, can be aluminium, copper, iron or its alloy.
The beneficial effects of the utility model are: since the shell of lamp as radiator, bigger area of dissipation is arranged, so radiating rate is fast; Make radiator with shell, reduced the heat radiation cost, thereby the light fixture cost of manufacture is low; Owing to do not need to install radiator, shell can be designed to various both artistic and practical shapes as required again again.Because the utility model rapid heat dissipation, thereby can improve the power of LED light fixture greatly.
