Abstract
Disclosed is a light emitting diode (LED) bulb. The LED bulb comprises a lamp holder, a radiator, a printed circuit board (PCB), an LED luminous component and a spherical surface lampshade, the LED luminous component is welded on the PCB, the PCB is connected with the radiator, a heat radiating groove is mounted on the side surface of the radiator, and a heat radiating hole and a guide wire passing hole are disposed on the PCB. The LED bulb has the advantages that the structure is simple, the air convection and heat radiating paths of an LED light source component to radiate heat in the air convection mode are increased by the aid of the heat radiating groove and the heat radiating hole on the PCB, the reliability of the LED light source component is improved, and the service life of an LED bulb lamp is prolonged.
Description
Technical field
The present invention relates to lighting technical field, relate in particular to a kind of LED lamp.
Background technology
At present, the LED bulb lamp have light efficiency height, life-span long, without showing that pollution, the characteristics such as energy-conservation are used widely.Existing its power drives of LED bulb lamp all is built in the aluminium radiator, simultaneously in order to insulate with aluminium radiator, adopt insulating tape or heat-shrinkable T bush that power drives is wrapped up, power drives is in whole sealing status, the power drives that causes being built in the aluminium radiator is carried out work under hot environment, shorten the service life of power drives, reduced the reliability of LED bulb lamp.
Summary of the invention
In order to overcome existing LED bulb lamp above shortcomings and defective, the invention provides the LED bulb lamp of a kind of simple in structure, good heat dissipation effect, long service life.
The technical scheme that the present invention adopts for achieving the above object is: a kind of LED ball bubble, and comprise lamp holder, radiator, PCB wiring board, be welded in LED luminescence component and sphere lampshade on the PCB wiring board, PCB wiring board and radiator lead to and connect.
The side of radiator has radiating groove.
The PCB wiring board is provided with louvre and wire cable-through hole.
LED ball bubble of the present invention, simple in structure, because the design of louvre on radiating groove and the PCB wiring board has increased cross-ventilation, increase the heat radiation approach that the LED light source assembly dispels the heat in cross-ventilated mode, improved the reliability of LED light source assembly and the life-span of LED bulb lamp.
Description of drawings
Fig. 1 is the structure chart of LED ball bubble of the present invention.
The specific embodiment
The structure of LED ball bubble of the present invention as shown in Figure 1, comprise lamp holder, aluminium radiator 1, PCB wiring board 3, be welded in LED luminescence component 6 and sphere lampshade on the PCB wiring board 3, be characterized in that PCB wiring board 3 is connected by fixing hole 4 usefulness bolts with aluminium radiator 1, the side of aluminium radiator 1 has radiating groove 7, and PCB wiring board 3 is provided with louvre 5 and wire cable-through hole 20.Because the design of louvre has increased cross-ventilation on radiating groove and the PCB wiring board, has increased the heat radiation approach that the LED light source assembly dispels the heat in cross-ventilated mode, has improved the reliability of LED light source assembly and the life-span of LED bulb lamp.
