Description
Technical field
The utility model relates to the LED lighting technical field, is specifically related to a kind of LED illuminating lamp with high efficiency and heat radiation function.
Background technology
Along with development of science and technology, led light source be considered to the 4th generation lighting source, led light source relies on the high and low power consumption of luminous efficiency, does not need advantages such as high pressure, security height; Be applied in various lighting fields widely; But when being some big area illuminations, because the power of led light source is bigger, the life-span of led light source and the operating temperature of node have closer getting in touch; Led light source has only 15%～25% electric energy to convert luminous energy in the course of the work; Remaining electric energy nearly all changes into heat energy, the temperature of led light source is raise, and every increase by 10 its reliabilities of degree of temperature will reduce half the.Heat radiation just becomes the big problem that led light source faces.Bad meeting directly causes the quick aging of led light source if dispel the heat, and stability reduces, and simultaneously, bad can the generation life-span that serious light decay influences lamp of dispelling the heat need be controlled at temperature about 60 ℃, and illuminating effect is best.The Traditional use fan dispels the heat because the life-span of fan is difficult to satisfy so long-time needs, in case the fan cisco unity malfunction, led light source will damage, and has also caused the waste of the energy; Adopt thermal grease to dispel the heat, can make the light source decay of led light source bigger, can't be applied in widely on the large area lighting; Radiating pieces such as use aluminium sheet radiator dispel the heat, because present aluminium sheet structural design is single, radiating effect is not good.
The utility model content
The technical problem that the utility model solved is to overcome employing fan mode of the prior art to increase energy consumption, adopt the thermal grease mode can cause that the led light source decay is bigger and adopt the not good problem of the single radiating effect of aluminium sheet structural design.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of led light source module; Comprise led light source pedestal, fin, circuit board, LED light emitting diode and LED beam angle lens; Said LED light emitting diode and LED beam angle lens constitute the LED illumination module, and said LED illumination module is installed on the circuit board, and said circuit board is installed on the led light source pedestal; It is characterized in that: said led light source pedestal and fin are one-body molded, and said fin is made up of a plurality of fins that vary in size.
Aforesaid a kind of led light source module is characterized in that: said a plurality of fins that vary in size are formed a bow font, and the fin that is arranged in the middle part of the bow word is densely distributed, and the fin that is arranged on bow word both sides distributes loose.
Aforesaid a kind of led light source module is characterized in that: the said densely distributed fin and the angle of led light source pedestal are between 70 ℃-90 ℃, and the said fin distribution angle loose and the led light source pedestal that is arranged on bow word both sides is between 30 ℃-70 ℃.
Aforesaid a kind of led light source module is characterized in that: said led light source pedestal is provided with set bolt.
Aforesaid a kind of led light source module is characterized in that: said led light source pedestal and fin material are copper or aluminium.
The beneficial effect of the utility model is: the utility model utilizes the led light source pedestal of copper or aluminum at first the heat that led light source produces once to be dispelled the heat; The fin of being made up of a plurality of fins once dispels the heat once more; And make the heat direction of transfer different through the different fin of a plurality of directions that vary in size and place; Thereby can cause the convection current of air, accelerate the speed that air is taken away heat, the effect that can dispel the heat is more obvious; Can effectively solve the heat dissipation problem of led light source, guarantee the service life and the intensity of illumination of led light source.

Fig. 2 is the side view of a kind of led light source module of the utility model.
The Reference numeral implication is following:
The 1:LED light source base; 2: fin; 3: fin; 4: set bolt; 5: circuit board; The 6:LED light emitting diode; 7:LED beam angle lens.
The specific embodiment
To combine Figure of description below, the utility model will be further described.
Like Fig. 1 and shown in Figure 2, a kind of led light source module comprises led light source pedestal 1, fin 2, circuit board 5, LED light emitting diode 6 and LED beam angle lens 7; Said LED light emitting diode 6 constitutes the LED illumination module with LED beam angle lens 7, and said LED illumination module is installed on the circuit board 5, and circuit board 5 is installed on the led light source pedestal 1 through set bolt 4; Led light source pedestal 1 is one-body molded with fin 2,, fin 2 is made up of a plurality of fins that vary in size 3; And form one and bend font; The bow font can make the fin heat make the formation convection current, accelerates the speed that air is taken away heat, because the mid portion and the 1 corresponding placement of led light source pedestal of bow font; So it is densely distributed to be arranged on the fin 3 at bow word middle part; Fin 3 distributions that are arranged on bow word both sides are loose, and the radiating effect at fin 3 intensive places is fast, can fast the quick phase of the heat both sides at led light source pedestal 1 place be spread.
The said densely distributed fin 3 and the angle of led light source pedestal 1 are between 70 ℃-90 ℃, and angle is got over the great achievement ladder the closer to the center increases, up to vertically; Can make the height of fin 3 higher, be convenient to quick heat radiating, the said fin 3 distributions angle loose and led light source pedestal 1 that is arranged on bow word both sides is between 30 ℃-70 ℃; Reduce away from the more little one-tenth ladder of center angle more, minimum is 30 ℃, comparatively speaking; The temperature at fin 2 middle parts can be big than the temperature of both sides; Therefore as above design the angle between the fin 3 and led light source pedestal 1 everywhere, can cause that the convection current of air is big relatively, take away the speed of heat.
Led light source pedestal 1 is copper or aluminium with fin 2 materials, the good heat dissipation effect of copper or aluminium, and cost is lower.
In sum; The utility model utilizes the led light source pedestal of copper or aluminum at first the heat that led light source produces once to be dispelled the heat; The fin of being made up of different fins once dispels the heat once more, and makes the heat direction of transfer different through the different fin of a plurality of directions that vary in size and place, thereby can cause the convection current of air; Accelerate air and take away the speed of heat; The effect that can dispel the heat is more obvious, can effectively solve the heat dissipation problem of led light source, guarantees the service life and the intensity of illumination of led light source.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
