Abstract
The invention relates to a high-power light-emitting diode (LED) lamp. The high-power LED lamp comprises a radiating plate, and a unit LED lamp of which the radiating surface is fixed in front of the radiating plate. The high-power LED lamp is characterized in that: a closed accommodating cavity is formed in the radiating plate; high-efficiency heat energy transfer liquid is filled in the closed accommodating cavity; and the side, which is far away from the unit LED lamp, in the closed accommodating cavity is provided with a plurality of grooves. Compared with the prior art, the high-power LED lamp has the advantage that: the heat of an aluminum plate fixedly connected with an LED lamp bead can quickly flow away, so that the temperature of the LED lamp bead is effectively and quickly reduced.
Description
Technical field
The present invention relates to a kind of electric light source.
Background technology
Existing high-powered LED lamp all needs to be provided with heat abstractor, and, radiating effect is good more, the power of LED lamp just can be high more, in the heat abstractor with the radiating effect of heat pipe for well, the heat pipe heat radiation of prior art all is to carry out from the aluminium sheet back that LED lamp pearl is fixed, thermal energy transfer from the lamp pearl to the aluminium sheet back can only be leaned on aluminium sheet self, the heat pipe self structure limits, and heat pipe can only contact with the area of aluminium sheet back fraction, thereby the heat energy on the aluminium sheet can not be delivered on the heat pipe rapidly.
Summary of the invention
Thereby the high-powered LED lamp that effectively, promptly reduces LED lamp pearl temperature that goal of the invention of the present invention is to provide the heat energy of the aluminium sheet that a kind of and LED lamp pearl be fixed together to flow away rapidly.
The present invention realizes like this, comprise that heat sink, radiating surface are fixed on the unit LEDs lamp of heat sink front, its special feature is to be provided with in the heat sink airtight cavity volume, be provided with the efficient heat energy transmission fluid in the airtight cavity volume, what airtight cavity volume was interior is provided with several grooves away from that side of unit LEDs lamp.During work, the heat energy that the unit LEDs lamp is distributed is delivered to efficient heat energy transmission fluid set in the airtight cavity volume rapidly by heat sink, the conversion of efficient heat energy transmission fluid by the latent heat of vaporization of liquid/gas conversion connected heat energy from the unit LEDs lamp that side of heat sink is delivered to the opposite side away from the heat sink of unit LEDs lamp, thereby the temperature when having reduced the work of unit LEDs lamp effectively, has significantly guaranteed that the unit LEDs lamp can work under powerful situation.The effect of groove had both increased thermal energy transfer area between efficient heat energy transmission fluid and heat sink, had also made things convenient for the liquid/gas conversion of efficient heat energy transmission fluid simultaneously.
Be provided with heat-dissipating fin at the heat sink back side, increasing the area of dissipation at the heat sink back side, the heat energy at the heat sink back side promptly distributed so that can be promptly.
Perhaps, at the heat sink back side several heat pipes are set, heat pipe is connected with groove on the heat sink content cavity.After being provided with heat pipe, the distance of liquid/gas conversion is increased, more help abundant, the effectively conversion of liquid/gas.Heat pipe is provided with several pieces heat-dissipating fins, can distribute rapidly with the heat energy that guarantees heat pipe.
The present invention compared with the prior art, thereby have the advantage that effectively, promptly reduces LED lamp pearl temperature that the heat energy of the aluminium sheet that is fixed together with LED lamp pearl can flow away rapidly.
