Abstract

The utility model discloses a light emitting diode (LED) point light source, and relates to the technical field of microelectronics application. The LED point light source is formed by a spherical lamp cover 1, a seal ring 2, a lamp base 4 and a lamp bead plate 5, wherein the lamp bead plate 5 is provided with two or more LED beads 6. The LED point light source has the advantages of being good in light source point accumulation performance, dustproof, waterproof, convenient to install and the like, and not only can be used for indoor decoration, but also can be used for decoration for lighting of buildings, bridge profiles, hotels, signboards, curtain walls and evening shows.

Description

A kind of LED spot light

Technical field

The utility model relates to the microelectronic applications technical field, particularly a kind of LED spot light.

Background technology

In the prior art, the LED spot light is as a kind of decorative lamp, in indoor and outdoor is decorated, particularly be used widely in building body, bridge profile, hotel, billboard, curtain wall and the lamplit decoration of evening show.Existing LED spot light, its kind and form are more, but most LED spot light since the transparency of lampshade better, the accumulation of light source is relatively poor; Simultaneously, it installs comparatively complicated.

Summary of the invention

For the existing deficiency of prior art, the accumulation that technical problem to be solved in the utility model provides a kind of light source is good, dustproof and waterproof and LED spot light easy for installation.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is a kind of LED spot light of design: be to be made of dome shape lampshade 1, sealing ring 2, lamp socket 4 and lamp pearl plate 5, at lamp pearl plate 5 devices LED lamp pearl 6 more than two or two arranged;

A, described lamp socket 4 are the round-ended cylinders that have with interior step 9, are evenly equipped with radiating fin 12 and the lampshade positioning table 15 more than two and the installing hole platform 16 more than two more than two on its external cylindrical surface, are provided with lamp pearl plate positioning table 8 on the interior step 9;

B, on the inwall of described dome shape lampshade 1, be provided with positioning spigot 3, this positioning spigot 3 with interior lampshade inwall on, be evenly arranged the astigmatic projection 7 more than five;

C, lamp pearl plate 5 devices are on lamp pearl plate positioning table 8, and the lower recess that the cross section is the sealing ring 2 of " H " shape is sleeved on the upper end of lamp socket 4, and the positioning spigot 3 of its upper grooves plug-in mounting lampshade 1 is by lampshade positioning table 15 location.

Described astigmatic projection 7 be shaped as hemispherical or cylindric or flat column or other shape.

The internal face of described lampshade 1 is processed into the frosted shape.

LED spot light of the present utility model arranges a plurality of astigmatic projections at the inwall of dome shape lampshade, and, also inner wall surface thereof is processed into the frosted shape, thereby the accumulation of its light source adds relatively.Simultaneously, positioning spigot is set in lampshade, and installs the sealing ring that the cross section is " H " shape additional, so have preferably dustproof and waterproof function.In addition, be evenly equipped with the installing hole platform at the external cylindrical surface of lamp socket, can directly install, thereby its installation be comparatively convenient.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.Following explanation is to adopt the mode that exemplifies, but protection domain of the present utility model should not be limited to this.

Present embodiment is to be made of lampshade 1, sealing ring 2, lamp socket 4 and lamp pearl plate 5.

Lamp socket 4 be one with the round-ended cylinder that has of interior step 9, in this, on the step 9, be provided with four lamp pearl plate positioning tables 8; Step groove hole 10 in middle formation of step 9 in this, a side in step groove hole 10 has cable-through hole 11 in this.Be evenly equipped with 24 (per three is one group, totally eight groups) radiating fins 12 on the external cylindrical surface of lamp socket 4, also be evenly equipped with four lampshade positioning tables 15 and four installing hole platforms 16, positioning table 15 and installing hole platform 16 are interspersed.The lamp pearl plate 5 of two or two above LED lamp pearls 6 is housed, and device is on lamp pearl plate positioning table 8; Electric wire 13 1 end connecting lamp pearl plates 5, the other end passes lamp socket 4 by cable-through hole 11, is connected with driving power 14.

Lampshade 1 is dome shape, on its inwall, be provided with one the circle positioning spigot 3 cylindraceous, this positioning spigot 3 with interior lampshade inwall on, be evenly arranged 13 the circle astigmatic projection 7; The shape of astigmatism projection 7 can be hemispherical or cylindric or flat column or other shape, and this example adopts hemispherical.The spherical internal face of lampshade 1 all is processed into the frosted shape.On lampshade 1, have lampshade positioning table hole and installing hole with lampshade positioning table 15 and installing hole platform 16 corresponding positions.

The sealing ring 2 of ring shape, the one lateral section is " H " shape, and the groove that is somebody's turn to do the bottom of " H " shape is sleeved on the upper end cylindrical portions may of lamp socket 4, and the groove on the top of its " H " shape is used for the positioning spigot 3 of plug-in mounting lampshade 1, by lampshade positioning table 15 location, be screwed.

Before the use, first LED spot light of the present utility model is installed in the position (installing fixing by installing hole, installing hole platform 16 with screw) that needs.

During use, the LED lamp pearl 6 on the lamp pearl plate 5 is luminous, and its light is penetrated by the lampshade 1 that is processed into the frosted shape through after scattering of astigmatic projection 7, especially as larger luminous point to around distribute.

During maintenance, directly will be installed on the hold-down screw dismounting in installing hole, the installing hole platform 16, light fixture integral body can be pulled down.

LED spot light of the present utility model is both applicable to interior decoration, also applicable to building body, bridge profile, hotel, billboard, curtain wall and the lamplit decoration of evening show.
