A kind of light-emitting device, comprise a lamp housing, one light emitting diode, one lampshade and a fixture, the cylindrical shell that described lamp housing comprises a substrate and extends from described substrate, described cylindrical shell offers a port, described light emitting diode comprises a circuit board and some intervals and is mounted on light emitting diode on described circuit board, the cover plate that described lampshade comprises a cover body and combines with described cover body, described cover body is attached to the inner surface of described cylindrical shell, described cover plate to cover on described cover body thus by airtight for described cover body, described cover plate caves in formation one depressed part, described depressed part offers a through hole, described fixture comprises a main part and projection a junction on described main part, described main part is placed in the depressed part of described cover plate, described connecting portion passes through hole thus is fixedly connected with described cover plate.
Preferably, described light emitting diode and lampshade are placed in described lamp housing, and light emitting diode module unit is stated in described lampshade residence, and described lampshade is fixed on described fixture.
Preferably, being distributed on described cylindrical shell and running through described cylindrical shell of described port interval.
Preferably, on the substrate, described some light emitting diodes are arranged towards described lamp housing in described circuit board installing.
Preferably, described cover body is placed in lamp housing, and described cover plate covers in described cover body one end near described lamp housing.
Preferably, a ring limit is extended in the bottom of described main part, and described ring limit is attached on the depressed part of described cover plate.
Beneficial effect: the utility model light-emitting device is attached to the inner surface of described cylindrical shell by described cover body, described cover plate to cover on described cover body thus by airtight for described cover body, described main part is placed in the depressed part of described cover plate, described connecting portion passes through hole thus is fixedly connected with described cover plate, the surrounding of described light emitting diode module forms a three-dimensional illumination space, increases lighting area and rising angle.

Fig. 2 is another three-dimensional exploded view of the utility model light-emitting device one preferred embodiment.
Fig. 3 is a three-dimensional assembly diagram of light-emitting device one preferred embodiment in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Using method of the present utility model is as follows:
Refer to Fig. 1 and Fig. 2, the utility model light-emitting device 100 better embodiment comprises a lamp housing 10, light emitting diode 20, be placed in described lamp housing 10 and to be placed in described lamp housing 10 and to cover the lampshade 30 of described light emitting diode module unit 20 and the fixture 40 of a fixing described lampshade 30.
The cylindrical shell 14 that described lamp housing 10 comprises a substrate 12 and extends downwards from described substrate 12.The cylindrical shell 14 of described lamp housing 10 offers a port 140.Being distributed on described cylindrical shell 14 and running through described cylindrical shell 14 of described port 140 interval.
Described light emitting diode 20 comprises a circuit board 22 and some intervals and is mounted on light emitting diode 24 on described circuit board 22.Described circuit board 22 is installed on described substrate 12.Described some light emitting diodes 24 are arranged towards described lamp housing 10.
The cover plate 34 that described lampshade 30 comprises a cover body 32 and combines with one end of described cover body 32.Described cover body 32 to be placed in lamp housing 10 and to be attached to the inner surface of described cylindrical shell 14.Described cover plate 34 covers in described cover body 32 one end near described lamp housing 10, thus by airtight for described cover body 32.The middle position of described cover plate 34 is caved in formation one depressed part 340.The middle position of described depressed part 340 offers a through hole 342, in order to be positioned in described depressed part 340 by described fixture 40.
A junction 44 that described fixture 40 comprises a main part 42 and protrudes from the middle position of described main part 42.A ring limit 420 is extended in the bottom of described main part 42.Time together with described lampshade 30 is assembled into described fixture 40, described main part 42 is placed in the depressed part 340 of described cover plate 34, described connecting portion 44 passes through hole 342 thus is fixedly connected with described cover plate 34, and described ring limit 420 is attached on the depressed part 340 of described cover plate 34.
