Description
Technical field
The utility model relates to a kind of LED light fixture, specifically, relates to a kind of LED bulb.
Background technology
Incandescent lamp and fluorescent lamp are all adopted in traditional illumination, but because its high energy consumption, the shortcoming that capacity usage ratio is low, eliminated by people day by day, the LED projecting lamp is as lighting apparatus, because the characteristics of its low energy consumption make that its purposes scope is more extensive, existing LED projecting lamp system is by base and be located at the LED lamp in this base and the camera lens that cooperates with the LED lamp etc. constitutes, because LED lamp and camera lens are used, after use, can produce the overheated phenomenon of camera lens unavoidably, and heat dissipation design of the prior art not very desirable, causes camera lens to destroy because of overheated, reduced the effect of printing opacity, also reduced service life simultaneously.
It is the patent of CN201014393Y that Patent Office of the People's Republic of China has announced notification number on January 30th, 2008, name is called: a kind of heat abstractor of high-capacity LED lamp, this device comprises substrate, LED lamp and heat sink, substrate is provided with penetrating mounting holes, the LED lamp is installed in this installing hole, the electrode of LED lamp is connected in substrate front side, is abutted against mutually between the heat-conducting plate of LED lamp and the heat sink and constitutes direct heat to conduct.Because this device is provided with heat sink, has increased the mechanism complexity of whole LED lamp, also increased volume simultaneously, need to consider the installation of heat sink in use, give to use and also be with inconvenience.
Summary of the invention
The utility model has mainly solved: the high energy consumption of traditional lighting lamp, the problem that capacity usage ratio is low, and the while has also solved the problem of general LED lamp weak heat-dissipating; Good heat dissipation effect, energy-conservation a kind of LED bulb are provided.
The technical solution adopted in the utility model is: a kind of LED bulb, and described LED bulb comprises lamp socket, lamp body, lampshade, aluminium base and constant-current source circuit; Lamp socket, lamp body, lampshade are connected and fixed successively; Described lamp body inside has the cylindrical hole of placing the constant-current source wiring board, and described cylindrical hole is provided with the step of placing aluminium base in the end near lampshade, described cylindrical hole outer most surrounding one circle fin; Described lampshade is circular-arc; Described lamp socket is horn-like, and the end and the side of lamp socket inside are provided with supply terminals, are provided with insulating tape between described end and the side; Several led light sources are installed on the described aluminium base, and led light source connects described constant-current source circuit, and constant-current source circuit connects supply terminals; Described LED bulb integral body is the incandescent lamp shape.
At first the constant-current source wiring board is put into the cylindrical hole of lamp body inside, aluminium base is fixed on the boss of lamp body inside, and LED lamp source is fixed on the aluminium base, the terminals of aluminium base are connected with lead with the constant-current source wiring board, are connected by lead between the power line of constant-current source wiring board and the supply terminals of lamp socket; Screwing lampshade and lamp socket at last can use.LED lamp source in use, the heat that sends passes to lamp body by aluminium base, the fin by the lamp body periphery dissipates heat again, good heat dissipation effect, because the similar incandescent lamp of contour structures can replace incandescent use, thereby reaches energy-conservation, the effect of long service life.
As preferably, the both ends of described lamp body are equipped with external screw thread, and described lamp socket is provided with the internal thread that cooperates with lamp body, and described lampshade opening part is provided with the internal thread that cooperates with lamp body, and lamp body is threaded with lampshade and lamp socket respectively.Also can adopt the mode of buckle to connect.
Thread connecting mode is stable, and maintenance time is long.
As preferably, the surface of described lampshade is provided with the annulus of a plurality of projectioies, allows the LED lamp send light and sends through modes such as reflection, diffuse reflection, refractions, makes light just soft.
Described lamp socket is provided with external screw thread outward, is convenient to install, and therefore can replace incandescent uses.
Also be provided with the annulus reflecting piece between described aluminium base and the lampshade, the effect of annulus reflecting piece is light and the process reflection that LED is sent, diffuse reflection, and refraction light backward reflects away forward again, brings into play the illumination efficiency of light to greatest extent.
The beneficial effect that the utility model is obtained is: adopt the lamp body have fin and aluminium base to make and increase the service life the good heat dissipation effect of LED lamp, play energy-conservation effect simultaneously.
