Chinese patent numbers 201020280974.7; Disclose a kind of New LED bulkhead lamp capable, comprised outer lampshade body, heat radiation lamellar body, light source body and light source cover body, the heat radiation lamellar body is located on the outer lampshade body; The light source body is located on the heat radiation lamellar body, and the light source external is provided with the light source cover body, and outer lampshade body inside is provided with interior lampshade; Interior lampshade and outer lampshade body are complementary; Be provided with the heat conduction colloid between outer lampshade body and the interior lampshade, the light source body is the led light source body, and the heat radiation lamellar body is provided with pin; Be provided with the heat conduction colloid between heat radiation lamellar body and the outer lampshade body, led light source body and light source cover body are complementary; The setting of heat conduction colloid between heat conduction colloid, heat radiation lamellar body and the outer lampshade body between interior lampshade, interior lampshade and the outer lampshade body; Reduced the thermal resistance between the contact-making surface; Strengthened radiating effect; Guarantee that the light source body works in the suitable temperature scope, prolonged lamp body service life, strengthened result of use; The energy has been practiced thrift in the employing of led light source body; The setting of pin on the heat radiation lamellar body is convenient to fixing and replacing lamp source body.

The LED bulkhead lamp capable of above-mentioned patent is compared with traditional bulkhead lamp capable; Have that volume is little, power consumption is low, service life, high brightness, environmental protection, characteristics such as sturdy and durable, but also have complex structure, big, the dustproof weak effect of assembly difficulty simultaneously and have ghost phenomena.Therefore be necessary to research and develop a kind of new LED bulkhead lamp capable, to satisfy growing bulkhead lamp capable demand.

The utility model content

In order to overcome the deficiency that existing LED bulkhead lamp capable exists complex structure, big, the dustproof weak effect of assembly difficulty and has ghost phenomena; The purpose of the utility model is to provide a kind of new LED bulkhead lamp capable; It is not only simple in structure, compact, be prone to as assembling, good dustproof effect, but also ghost image not.

To achieve these goals, the utility model has adopted following technical scheme: design a kind of New LED bulkhead lamp capable, comprise lampshade, led light source assembly, the led light source assembly comprises; Driving power module and one side are provided with the PCB circuit boards of some LED lamp pearls, and PCB circuit board shape is consistent with the uncovered shape of lampshade, and it is uncovered and be embedded in the interior open-mouth of lampshade to be slightly less than lampshade.

In order to reach better purpose, further, the utility model also has following technical characterictic;

Said lampshade opening end is connected with a transparent protective cover that matees each other with its shape and size.

Be perfused with thermal paste around the edge that described PCB circuit board and lampshade are fitted.

Described lampshade outer wall is provided with at least two movable latch hooks in order to fixing transparent protective cover.Enclosed by an O-ring seal around the transparent protective cover.

Be provided with an O-ring seal between described transparent protective cover and the lampshade opening end.

Described driving power module is installed in the lampshade rear end.

Described LED lamp pearl is the small light pearl.

The PCB circuit board of the said LED of being provided with lamp pearl simultaneously is coated with reflector layer, and this reflector layer is heavy tin layer.

Owing to adopted technique scheme; The PCB circuit board that one side is coated with heat dissipating layer is embedded in open-mouth in the lampshade; In order to reach fixing PCB circuit board and to increase the purpose of heat radiation contact-making surface; Around the edge of PCB circuit board and lampshade applying, be perfused with thermal paste; In order to reach the purpose of dustproof and waterproof, also be connected with a transparent protective cover at the lampshade opening end, the utility model is compared with existing bulkhead lamp capable to have: start required voltage, electric current is less, heating is less, applied widely, no potential safety hazard, also have simple in structure, compact, easy in assembling, good dustproof effect and ghost image not.
