Described upper cover is connected by screw-threaded coupling with lower cover.

Described substrate rear end face is provided with can the contact pin of external power supply.

Described LED power supply circuits comprise rectifier bridge, high-voltage linear constant current IC, the external 220V of described rectifier bridge or high-voltage DC power supply, the direct current output cathode of described rectifier bridge is connected to LED chip group, described LED chip group is connected with the output of high-voltage linear constant current IC, and the reference voltage output end of described high-voltage linear constant current IC is connected with the direct current output negative pole of rectifier bridge by after one or more resistance.

The LED drive chip of described high-voltage linear constant current IC to be model be SM2082C.

The beneficial effects of the utility model are: a kind of LED lampet, comprise light fitting body, described light fitting body comprises upper cover, lower cover, the light-passing board being arranged on upper cover end face and the light source board be arranged between upper cover and lower cover, described light source board comprises substrate, be arranged on the LED chip group of substrate front end face, described substrate front end face is provided with LED connecting circuit, described substrate rear end face is provided with LED power supply circuits and is provided with the electronic component of LED power supply circuits, volume of the present utility model is little, structure is simple, and be configured with independently power supply circuits, realize single lamp to control, light source module can be used as use, the light source module realizing LED lamp is replaced, reduce the cost that light fixture is safeguarded, use very convenient, and the utility model also can directly adopt 220V AC power or high-voltage DC power supply to power, the scope of application is wider, practicality is stronger.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is decomposing schematic representation of the present utility model;

Fig. 3 is circuit theory schematic diagram of the present utility model.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of the utility model specific embodiment, as shown in the figure, a kind of LED lampet, comprise light fitting body, described light fitting body comprises upper cover 1, lower cover 2, the light-passing board 5 being arranged on upper cover 1 end face and the light source board be arranged between upper cover 1 and lower cover 2, described light source board comprises substrate 3, be arranged on the LED chip group 4 of substrate 3 front end face, described substrate 3 front end face is provided with LED connecting circuit, described substrate 3 rear end face is provided with LED power supply circuits and is provided with the electronic component of LED power supply circuits, volume of the present utility model is little, structure is simple, and be configured with independently power supply circuits, realize single lamp to control, light source module can be used as use, the light source module realizing LED lamp is replaced, reduce the cost that light fixture is safeguarded, use very convenient, when being particularly applied on Crystal lamp, the trouble of refitting of dismantling is saved in maintenance aspect, break down if any one and change, without the need to changing other, be user-friendly to.

As preferably, in the present embodiment, described upper cover 1 is connected by screw-threaded coupling with lower cover 2, assembles very convenient, and compact conformation, certainly, in specific implementation process, also can adopt the modes such as buckle, screens connection, splicing, not be described further at this.
