Abstract
The utility model provides a high-efficiency heat-radiation LED (light emitting diode) lamp, comprising a power supply connecting part, a heat-radiation part and a luminous part, wherein a plurality of LED chips are arranged in the luminous part, and the heat-radiation part is arranged close to the luminous part, a radiating fin is arranged in the heat-radiation part, and the heat-radiation part is provided with a plurality of opening holes. The heat-radiation part is provided with a through hole; therefore, the air inside the heat-radiation part can flow and be exchanged, thereby improving the heat-radiation effect.
Description
Technical field
The utility model belongs to the LED field of light fittings, and is concrete, relates to a kind of LED light fixture with high efficiency and heat radiation function.
Background technology
LED has that energy consumption is low, the advantage of long service life, has begun progressively to substitute conventional light source now.But single led luminosity is not enough, and the LED lamp generally adopts led array formula structure, produces the difficult problem of LED lamp heat radiation thus.If the heat energy on the LED lamp can not in time distribute, the interior junction temperature of PN junction of led chip is raise, this can cause the red shift of led chip peak wavelength; The absworption peak that departs from fluorescent material causes that power efficiency descends, and causes fluorescent material aging; Device aging etc. is quickened in the epoxy resin flavescence.
The utility model content
To above-mentioned deficiency; The utility model provides a kind of high-efficiency heat radiating LED lamp, and it comprises power supply connecting portion, radiating part and illuminating part, in said illuminating part, is provided with a plurality of led chips; Radiating part is close to the illuminating part setting; Wherein, in radiating part, be provided with fin, on radiating part, be provided with a plurality of perforates.Through hole is set, at the exchange of can flowing of the inner air of radiating part, raising radiating effect on radiating part.
Preferably, fin comprises heat dissipation base, and radiating fin is perpendicular to heat dissipation base, and radiating fin part at least is staggered.Staggered radiating fin makes and utilizes the air fluxion strap to walk heat by the mobile smooth and easy of air, plays better radiating effect.
Preferably, radiating fin partly is arranged on the fin edge, and part is arranged on the inside of fin.
Description of drawings
Shown in Figure 1 is the structural representation of LED light fixture among the utility model embodiment.
Shown in Figure 2 is the structural representation of LED fin among the utility model embodiment.
The specific embodiment
Below in conjunction with embodiment the utility model is described further.
Be illustrated in figure 1 as the structural representation of LED light fixture among the utility model embodiment; As shown in the figure, this LED light fixture has comprised power supply connecting portion 11, radiating part 12 and illuminating part 13, in illuminating part 13; Be provided with a plurality of led chips; Radiating part 12 is provided with near illuminating part 13, in radiating part 12, is provided with fin, and radiating part 12 is provided with a plurality of perforates 121.Through hole is set, at the exchange of can flowing of the inner air of radiating part, raising radiating effect on radiating part.
Be illustrated in figure 2 as the structural representation of LED radiating fin among the utility model embodiment, as shown in the figure, this fin has comprised base 14 and radiating fin 141; Base contacts with the back side of led chip; Be used to conduct heat, radiating fin 141 is used for heat radiation perpendicular to the base setting.
Preferably, in the present embodiment, be staggered inside and outside the radiating fin 141, part is arranged on fin edge (outside), and part is arranged on the inside of fin.Staggered radiating fin makes and utilizes the air fluxion strap to walk heat by the mobile smooth and easy of air, plays better radiating effect.Being staggered here; Be not limited to structure shown in the embodiment; Comprised that inner heat fins and external heat fins are staggered one by one or are staggered in twos, also comprised inner heat fins and the external heat fins asymmetric various compound modes such as be staggered that are staggered.In the utility model, fin simple in structure, production process is few, and material therefor is few.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
Claims (3)
