The LED lamp provided by the utility model has the advantages of high light intensity, good heat radiation and long service life.
Description
Technical field
The utility model relates to a kind of lighting, particularly a kind of LED lamp.
Background technology
In recent years, the LED lamp is because advantages such as its brightness that has height, long service life, power saving, environmental protection begin to progress into people's life, and the alternative gradually original lighting of beginning, becomes main lighting in people's life.The critical piece of LED lamp is a LED lamp pearl, and the lamp pearl is in when illumination, and caloric value is bigger, if can not efficiently radiates heat; Then As time goes on and gradually the light decay of lamp pearl can increase, the brightness meeting deepening of lamp, and the service life of lamp is shorter; Therefore, depend primarily on radiator structure the service life of LED lamp, existing LED lamp generally is to dispel the heat through the mode of passive heat radiation; Promptly the fin through heat-conducting dispels the heat, and radiating effect is relatively poor, and also some is through the blower fan forced heat radiation; This radiating mode generally is used for the bigger LED lamp of power, and the cost when this LED lamp manufacturing and use is all than higher, and the effect of heat radiation is not fine.
Summary of the invention
The purpose of the utility model is to the bad problem of thermal diffusivity of the existing LED lamp existence described in the background technology a kind of LED lamp that can solve foregoing problems to be provided.
The technical scheme of the goal of the invention of realization the utility model is following:
A kind of LED lamp; It comprises that lamp housing, LED lamp pearl, circuit board and constant-current supply, lamp housing are cylindric, and set inside has cavity, and constant-current supply is arranged in this cavity; The outside of lamp housing internal cavity radially is provided with some fin along lamp housing; The lamp housing bottom is provided with conducting strip, and circuit board is fixed on the conducting strip, and pearl is arranged on the circuit board lamp.
Described circuit board is aluminium base circuit board.
Described LED lamp pearl is SMD LED lamp pearl.
Be filled with water between the described fin.
Top at described lamp housing is provided with water inlet.
The beneficial effect of the utility model is for because be provided with cavity in the lamp housing of the LED lamp of the utility model, and power supply is arranged in this cavity, radially is provided with some fin in the outside of lamp housing internal cavity along lamp housing; The lamp housing bottom is provided with conducting strip, and circuit board is fixed on the conducting strip, and the lamp pearl is arranged on the circuit board; Therefore; The heat that the lamp pearl sends passes to conducting strip through circuit board, and at the outer surface through fin conductive to lamp housing, the heat that power supply produces also can conduct to the outer surface of lamp housing through conducting strip; Through this radiating mode, can effectively improve the efficient of heat radiation.In order to improve radiating effect, adopt aluminium base circuit board and SMD lamp pearl, the heat of lamp pearl generation can conduct faster like this; In order to control the temperature of lamp housing; Make circuit board remain lower temperature, be filled with water between the fin, can take away the part heat when water receives thermal evaporation; Top at lamp housing is provided with water inlet, conveniently adds water at any time according to the situation of water in the lamp housing.Through above setting, on the one hand, the heat that the lamp pearl produces can be rapidly through fin conductive to lamp housing surface, and because of the effect of water in the lamp housing, circuit board can keep lower temperature on the other hand, accelerates the transmission of heat, makes the service life of LED lamp more permanent.
Description of drawings
Fig. 1 is the sketch map of the utility model;
Among the figure, 1 is lamp housing, and 2 is LED lamp pearl, and 3 is circuit board, and 4 is constant-current supply, and 5 is cavity, and 6 is fin, and 7 is conducting strip, and 8 is water inlet.
The specific embodiment
With reference to a kind of LED lamp shown in Figure 1; It comprises lamp housing 1, LED lamp pearl 2, circuit board 3 and constant-current supply 4, lamp housing 1 for cylindric, and set inside has cavity 5, and constant-current supply 4 is arranged in this cavity 5; The outside of lamp housing 1 internal cavity 5 is along the some fin 6 of radially being provided with of lamp housing 1; Lamp housing 1 bottom is provided with conducting strip 7, and circuit board 3 is fixed on the conducting strip 7, and the lamp pearl is arranged on the circuit board 3; Described circuit board 3 is aluminium base circuit board 3; Described LED lamp pearl 2 is SMD LED lamp pearl 2; Be filled with water between the described fin 6; Be provided with water inlet 8 on the top of described lamp housing 1.Because be provided with cavity 5 in the lamp housing 1 of the LED lamp of the utility model, power supply is arranged in this cavity 5, in the outside of lamp housing 1 internal cavity 5 along the some fin 6 of radially being provided with of lamp housing 1; Lamp housing 1 bottom is provided with conducting strip 7, and circuit board 3 is fixed on the conducting strip 7, and the lamp pearl is arranged on the circuit board 3; Therefore; The heat that the lamp pearl sends passes to conducting strip 7 through circuit board 3, and at the outer surface that conducts to lamp housing 1 through fin 6, the heat that power supply produces also can conduct to the outer surface of lamp housing 1 through conducting strip 7; Through this radiating mode, can effectively improve the efficient of heat radiation.In order to improve radiating effect, adopt aluminium base circuit board 3 and SMD lamp pearl, the heat of lamp pearl generation can conduct faster like this; In order to control the temperature of lamp housing 1; Make circuit board 3 remain lower temperature, be filled with water between the fin 6, can take away the part heat when water receives thermal evaporation; Be provided with water inlet 8 on the top of lamp housing 1, convenient situation according to water in the lamp housing 1 is added water at any time.Through above setting, on the one hand, the heat that the lamp pearl produces can conduct to lamp housing 1 surface through fin 6 rapidly; On the other hand because the effect of water in the lamp housing 1; Circuit board 3 can keep lower temperature, accelerates the transmission of heat, makes the service life of LED lamp more permanent.
