Abstract
The utility model discloses a heat dissipation device for an LED (light-emitting diode) bulb lamp. The LED bulb lamp comprises the heat dissipation device, a heat dissipation plate, a lamp plate, a circuit driving plate, an LED light source, a lamp cap and a lamp cover; the circuit driving plate is provided with a component; the LED light source is connected on the lamp plate; the lamp plate is fixedly connected with the heat dissipation plate; the circuit driving plate is connected in the heat dissipation device and electrically connected with the LED light source; the lamp cover is connected with the heat dissipation device; the lamp cap is fixedly connected with the heat dissipation device; and the heat dissipation plate and the heat dissipation device are fixedly connected with each other and formed integrally. Because the heat dissipation plate and the heat dissipation device are formed integrally, the heat resistance of the lamp plate is reduced when the lamp plate dissipates heat, most of the heat can be transferred to the heat dissipation device through the heat dissipation plate, and a good heat dissipation effect is achieved.
Description
Technical field
The utility model relates to a kind of radiator of LED bulb lamp.
Background technology
Existing LED bulb lamp, such as Fig. 1 and Fig. 2, its radiator 100 ' is split type with heat sink 200 ', heat sink 200 ' is fixed on the radiator 100 ' by the mode of riveting, the production technology more complicated.Simultaneously, radiator 100 ' be split type with heat sink 200 ' so that when dispelling the heat thermal resistance large, radiating effect is bad.
The utility model content
The utility model provides a kind of radiator of LED bulb lamp, and it has overcome the existing deficiency of background technology.The technical scheme that adopts that the utility model solves its technical problem is: a kind of radiator of LED bulb lamp, it is characterized in that: described LED bulb lamp comprises radiator (100), heat sink (200), lamp plate (300), attaching has the circuit drives plate of components and parts, led light source (310), lamp holder and lampshade, described led light source (310) is installed on the lamp plate (300), lamp plate (300) is fixedly attached on heat sink (200), described circuit drives plate is installed in the radiator (100) and is electrically connected led light source (310), described lampshade is installed in radiator (100), described lamp holder is fixedly attached in radiator (100), and described heat sink (200) and radiator (100) are fixedly connected and are formed in one.
