The hemispherical plastic LED bulb lamp has the advantages that the radiating performance is good, the lighting power can be effectively improved, and the market scope of hemispherical plastic LED bulb lamps is expanded greatly.

Description

A kind of LED plastic cement hemispherical bulb lamp

Technical field

The utility model relates to LED lamp field, is specially a kind of LED plastic cement hemispherical bulb lamp.

Background technology

The LED lamp is a kind of light emitting semiconductor device commonly used, has the advantage of energy-conserving and environment-protective.The overall plastic glue shell of prior art hemispherical bulb is with low cost, good looking appearance, but heat dispersion is bad, and luminous power is little, only is applicable to that 7W is following, the electricity-saving lamp market of non-360 degree light firing angle.

The utility model content

The purpose of this utility model provides a kind of LED plastic cement hemispherical bulb lamp, to solve the bad problem of prior art overall plastic glue shell hemispherical bulb heat radiation performance.

In order to achieve the above object, the technical scheme that adopts of the utility model is:

A kind of LED plastic cement hemispherical bulb lamp, include hollow plastic body, be connected the hollow hemisphere shape die casting at plastic body top, be connected the plastic body top and cover on the outer teething ring of die casting, it is characterized in that: the hemispherical diffuser that covers die casting is installed on the teething ring, form the multiple tracks wire casing on the described die casting hemisphere face, be inlaid with lamp pearl module in the wire casing respectively, described die casting inwall is connected with multiple tracks vertical fin that extends in the die casting, described plastic body and die casting joint portion outer wall are provided with a plurality of ring-type pores, and the plastic body bottom is connected with lamp holder.

Described a kind of LED plastic cement hemispherical bulb lamp, it is characterized in that: described wire casing is distributed on the die casting radially, perhaps being many parallel wire is distributed on the die casting, when wire casing distributed radially, the lamp pearl module in a plurality of wire casings connected by an annular FPC that is arranged on the die casting; When wire casing was many parallel wire and distributes, the lamp pearl module in a plurality of wire casings connected by a linear FPC that is arranged on the die casting.

Described a kind of LED plastic cement hemispherical bulb lamp is characterized in that: be coated with reflecting coating on the described die casting hemisphere face.

Described a kind of LED plastic cement hemispherical bulb lamp, it is characterized in that: described die casting top center has through hole.

Described a kind of LED plastic cement hemispherical bulb lamp, it is characterized in that: described die casting inwall has the vertical fin of multiple tracks.

The utility model will carry the flexible all-metal nanometer light of circuit pearl module and directly be fixed in the die casting wire casing as radiator, the die casting inwall has the vertical fin of multiple tracks, establish power supply in the plastic body, connecting line passes from through hole between power supply and the lamp pearl module, diffuser is fixed on the teething ring, and teething ring surrounds die casting.Plastic body and die casting joint portion outer wall have a plurality of ring-type pores, and fin is by ring-type pore and the direct fluid of extraneous air in the die casting.Also handle with nanometer technology on the utility model die casting surface simultaneously.

The utlity model has heat dispersion preferably, can effectively improve the luminous power of LED plastic cement hemispherical lamp bulb, expanded the market scope of LED plastic cement hemispherical lamp bulb greatly.

Fig. 3 is the utility model cross-like distribution schematic diagram anyhow.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3.A kind of LED plastic cement hemispherical bulb lamp, include hollow plastic body 1, be connected the hollow hemisphere shape die casting 2 at plastic body 1 top, be connected plastic body 1 top and cover on die casting 2 teething ring 3 outward, the hemispherical diffuser 4 that covers die casting 2 is installed on the teething ring 3, form the multiple tracks wire casing on die casting 2 hemisphere faces, be inlaid with lamp pearl module 5 in the wire casing respectively, die casting 2 inwalls are connected with multiple tracks to the die casting 2 interior vertical fin 6 that extend, plastic body 1 is provided with a plurality of ring-type pores with die casting 2 joint portion outer walls, and plastic body 1 bottom is connected with lamp holder 7.

Wire casing is distributed on the die casting 2 radially, perhaps is many parallel wire and is distributed on the die casting 2, and when wire casing distributed radially, the lamp pearl module 5 in a plurality of wire casings connected by an annular FPC 8 that is arranged on the die casting 2; When wire casing was many parallel wire and distributes, the lamp pearl module 5 in a plurality of wire casings connected by a linear FPC 8 that is arranged on the die casting 2.

Be coated with reflecting coating on die casting 2 hemisphere faces.

Die casting 2 top center have through hole.

The utility model is installed in the lamp pearl module of the all-metal support on flexible charged road in the wire casing of arcuation die casting, and the coating reflecting coating is to strengthen the light reflection on the die casting.Die casting and plastic body connect as one, and plastic body and die casting connecting portion outer wall have a plurality of ring-type pores, and the fin of die casting inwall is directly contacted with extraneous air, are convenient to heat radiation.Lamp pearl module is connected in series by a FPC, and FPC also is connected with power line.
