Abstract
The utility model discloses a light-emitting diode (LED) bulb light which comprises a lamp cap, a lamp cap connector, a power supply, a radiator, a light-emitting diode (LED) light bead and a light-emitting cover. The lamp cap is fixedly connected with the lamp cap connector. A first cavity is formed by the lamp cap connector and the radiator in a surrounding mode and is provided with the power supply. A second cavity is formed by the light-emitting cover and the radiator in a surrounding mode. The LED light bead is arranged inside the second cavity and is directly fixed on the radiator, and the light-emitting surface of the LED light bead is towards the light-emitting cover. The LED light bead is directly fixed on the radiator in an LED bulb light, so that the efficiency of heat dissipation is improved and the service life of the LED bulb light is prolonged. Furthermore, a light source cap and a first fixing screw are arranged on the LED bulb light, and the LED light bead is clamped between the light source cap and the radiator in bolt mode, so that the three-dimensional heat dissipation environment is formed. The heat generated is discharged directly through the radiator. The LED bulb light is simple in structure and good in heat dissipation effect.
Description
Technical field
The utility model relates to lighting technical field, relates in particular to a kind of LED bulb lamp.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.LED is encapsulated in the epoxy resin the inside completely, and it is all firmer than bulb and fluorescent tube.There is not loosening part in its lamp body, so that LED has non-damageable advantage.But heat radiation is the most important factor that affects the LED lamp life-span.Radiating effect is better, and the life-span of LED lamp is just long, otherwise radiating effect is poorer, and the life-span of LED lamp is just short.
The utility model content
For the weak point that exists in the above-mentioned technology, the utility model provides a kind of LED bulb lamp of simple in structure, good heat dissipation effect.
For achieving the above object, the utility model provides a kind of LED bulb lamp, comprise lamp holder, connecting piece of lamp cap, power supply, radiator, LED lamp pearl and go out light shield, described lamp holder is fixedly connected with connecting piece of lamp cap, described connecting piece of lamp cap and radiator enclose the first cavity, and described power supply places the first cavity; Describedly go out light shield and radiator encloses the second cavity, described LED lamp pearl places the second cavity and directly is fixed on the radiator, and the exiting surface of described LED lamp pearl is towards going out light shield.
Wherein, described LED bulb lamp also comprises the first fixed screw and light source cover, described the first fixed screw and light source cover place the second cavity, and described light source cover is fixed on the radiator by the first fixed screw, and LED lamp pearl is clamped between light source cover and the radiator.
Wherein, described LED bulb lamp also comprises the second fixed screw, and described lamp holder is fixedly connected with by the second fixed screw with connecting piece of lamp cap.
The beneficial effects of the utility model are: compared with prior art, the LED bulb lamp that the utility model provides directly is fixed on LED lamp pearl on the radiator, can improve heat dissipation, thereby prolongs the service life of LED bulb lamp.Further, by light source cover and the first fixed screw are set, by the mode that is spirally connected LED lamp pearl is fastened between light source cover and the radiator, can forms three-dimensional heat dissipation environment, the heat of generation is directly derived by radiator, and is simple in structure, good heat dissipation effect.
