Abstract

The utility model discloses a light emitting diode (LED) lamp, which comprises a printed circuit board (PCB), LED lamp beads, a first heat dissipation sheet, a second heat dissipation sheet and a heat conduction tube, wherein the LED lamp beads are arranged below the PCB; the first heat dissipation sheet is arranged above the PCB; the lower side of the heat conduction tube tightly contacts the first heat dissipation sheet; the upper side of the heat conduction tube tightly contacts the second heat dissipation sheet; and a coolant is arranged in the heat conduction tube. By adopting the measure, heat emitted by the LED can be timely and effectively brought away and prevented from being accumulated, so that the working temperature of the LED is effectively reduced, and the service life of the LED is prolonged.

Description

A kind of LED lamp

Technical field

The utility model relates to lighting technical field, especially a kind of LED lamp.

Background technology

Along with development of semiconductor,, energy-conservation because LED has the brightness height as light emitting source; Advantages such as noiselessness; So the application of LED illuminating lamp also more and more widely, and still along with the continuous increase of LED lamp power, the heat dissipation problem of LED lamp becomes the huge obstacle of LED illuminating lamp.

Existing technology generally is to adopt heat conducting mode that LED is dispelled the heat, and when power is big, realizes the heat radiation of LED through increasing area of dissipation; Clasper for example is set on fin; Increase fin size etc., if when LED power is big, the volume of fin is also bigger; Sometimes even can not satisfy the requirement of heat radiation, shorten the service life of LED.

The utility model content

The technical problem that the utility model mainly solves provides a kind of LED lamp, can effectively solve the heat dissipation problem of LED, prolongs the service life of LED.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of LED lamp, comprise pcb board, LED lamp pearl, first fin, second fin, heat pipe, and said LED lamp pearl is arranged on the below of pcb board; Said first fin is arranged on the top of pcb board; The downside of said heat pipe closely contacts with first fin, and the upside of said heat pipe closely contacts with second fin, is provided with refrigerant in the said heat pipe.

In preferred embodiment of the utility model, the right side of said heat pipe is higher than the left side.

In preferred embodiment of the utility model, said second fin is provided with clasper.

In preferred embodiment of the utility model, the top of said second fin is provided with fan.

After implementing above technical measures, have following technique effect:

1. the utility model circulates in heat pipe through refrigerant, and the heat that can timely and effectively LED be sent is taken away, and effectively solves the heat dissipation problem of LED lamp, prolongs the service life of LED.

2. the utility model is simple in structure, and is easy to process.

Description of drawings

Fig. 1 is the structural representation of the utility model LED lamp.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

The utility model embodiment comprises:

As shown in Figure 1, a kind of LED lamp comprises pcb board 1, LED lamp pearl 2, first fin 3, second fin 4, heat pipe 5; Said LED lamp pearl 2 is arranged on the below of pcb board 1, and LED lamp pearl 2 electrically connects with pcb board 1, and said first fin 3 is arranged on the top of pcb board 1; The downside 52 of said heat pipe closely contacts with first fin 3, and the downside 52 of heat pipe can embed first fin 3, and heat pipe is fully contacted with first fin; The upside 53 of said heat pipe closely contacts with second fin 4, and second fin is provided with clasper 42, increases area of dissipation; Help further heat radiation, the right side 51 of said heat pipe is higher than the left side 54 of heat pipe, is provided with refrigerant in the heat pipe 5; Refrigerant is the meeting generating gasification after being heated, and forms gas, and liquefaction generation liquid takes place in cooling.

Behind the luminous generation heat of LED, heat is absorbed by first fin rapidly, the refrigerant generation heat exchange in first fin and the heat pipe; The refrigerant back generating gasification of being heated forms gas, and the refrigerant after the gasification gets into heat pipe upsides 53 along the right side 51 of heat pipe, carries out heat exchange at the upside refrigerant and second fin of heat pipe; Refrigerant cooling is liquefied, because the right side of heat pipe is higher than the left side, so the refrigerant after liquefying is along the flow through left side 54 of heat pipe of the upside 53 of heat pipe; Turn back to the downside 52 of heat pipe, refrigerant is constantly circulation in heat pipe, constantly transmits heat; The heat that therefore can in time LED be sent is taken away; Prevent that heat from gathering, effectively reduce the operating temperature of LED, prolong the service life of LED.

In preferred embodiment of the utility model, the top of said second fin is provided with fan, helps further heat radiation.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
