Abstract
The utility model discloses a heat-radiating LED (Light-Emitting Diode) bulb lamp, which comprises a lamp holder, a heat radiator, a spherical lamp shade and an LED light source mounted in the heat radiator. The lamp holder, the heat radiator and the spherical lamp shade are sequentially connected from top to bottom; the heat radiator is of a hollow cylinder shape; spiral radiating fins are evenly distributed at the outside periphery of the hollow cylinder; and the spiral radiating fins are radially distributed along the axle center of the cylinder from inside to outside. With the adoption of the technical scheme disclosed by the utility model, the spiral radiating fins are evenly distributed at the outside periphery of the cylinder of the heat radiator, heat-radiating spaces of the spiral radiating fins are more than those of straight radiating fins, and thus, the heat-radiating effect is better; and meanwhile, the spiral radiating fins are radially arranged along the bulb lamp, the fast flowing of airflow along gaps among the radiating fins in the vertical direction is facilitated, and thus, the heat-radiating efficiency is increased, and the service life of the LED lamp is prolonged.
Description
Technical fieldThe utility model relates to the LED bulb lamp, relates in particular to a kind of LED bulb lamp of high efficiency and heat radiation.
Background technologyUnder the situation that global energy shortage, environmental requirement improve constantly, the semiconductor illuminating light source that development has energy-saving and environmental protection, long-life, an advantage such as radiationless is to energy-saving and environmental protection and build a conservation-minded society and have the important strategic meaning.The LED bulb lamp has light efficiency height, life-span length, no mercury pollution, energy-conservation about 50% with first-class characteristics, and can directly replace existing incandescent lamp, electricity-saving lamp, in the hotel, lighting field such as hotel, furniture is widely used.
Because the caloric value of LED lamp is very big, and on the market the fansink designs of LED bulb lamp is improper at present, makes heat build-up in the bulb lamp, and led light source has shortened the service life of bulb lamp greatly because of overheated light decay.
Summary of the inventionIn order to overcome the deficiency of prior art, the purpose of the utility model provides a kind of LED bulb lamp of high efficiency and heat radiation simple in structure.
The LED bulb lamp of a kind of high efficiency and heat radiation of the utility model; It comprises lamp socket, lamp holder, radiator, sphere lampshade and is installed on the led light source in the radiator; Lamp socket, lamp holder, radiator, sphere lampshade connect from top to bottom successively; Said radiator comprises the groove cylinder and along the surperficial equally distributed radiating fin of cylindrical periphery, also is provided with the plural logical heat of loosing on the open circles post jamb.
Said radiating fin radially is provided with along bulb lamp.
Adopt the technical scheme of the utility model; The cylindrical periphery surface of radiator is evenly distributed with radiating fin; And be provided with the heat radiation groove on the cylindrical wall, increased area of dissipation, more fully heat is diffused to the air from bulb lamp inside; Prevent that LED lamp source operating temperature is too high, avoided heat build-up in the bulb lamp; Simultaneously, radiating fin radially is provided with along bulb lamp, helps air-flow and flows fast in vertical direction along the space between the radiating fin, and then improved radiating efficiency, prolongs the service life of LED lamp.
Description of drawingsBelow in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the LED bulb lamp of the utility model high efficiency and heat radiation.
The specific embodimentAs shown in Figure 1; The LED bulb lamp of a kind of high efficiency and heat radiation of the utility model; It comprises lamp socket 1, lamp holder 2, radiator 3, sphere lampshade 4 and is installed on the led light source 5 in the radiator 3; Lamp socket 1, lamp holder 2, radiator 3, sphere lampshade 4 connect from top to bottom successively, and said radiator 3 comprises hollow cylinder 31 and along the equally distributed radiating fin 32 of cylinder 31 outer surfaces, also is provided with plural heat radiation groove 33 on hollow cylinder 31 walls.
Adopt above structure; Cylinder 31 outer surfaces of radiator 3 are evenly distributed with radiating fin 32; And be provided with heat radiation groove 33 on the cylindrical wall 31, increased area of dissipation, more fully heat is diffused to the air from bulb lamp inside; Prevent that LED lamp source 5 operating temperatures are too high, avoided heat build-up in the bulb lamp.
Said radiating fin 32 radially is provided with along bulb lamp, helps air-flow and flows fast in vertical direction along the space between the radiating fin 32, and then improved radiating efficiency.
