Abstract

The utility model discloses a small-power light-emitting diode (LED) lamp with an improved structure. The small-power LED lamp with the improved structure comprises an LED, an aluminum substrate, a radiator and a lamp cap, wherein the LED is arranged on the aluminum substrate, the aluminum substrate is fixedly arranged on the top of the radiator, the lamp cap is electrically connected with the LED, and the small-power LED lamp with the improved structure further comprises a hollow power source placing column. Due to the fact that the insulating power source placing column is arranged, a power source is isolated from an aluminum insert, the power source or a wire is not directly contacted with the conductive aluminum insert, the electric leakage of the power source or a short circuit is effectively prevented, and therefore the power source and users are better protected.

A large amount of led chips is integrated on the little aluminium base of area, and the heat that produces during the work of LED lamp gathers easily, if untimely exothermic temperature can constantly raise, of long duration just can damage the LED lamp, so the LED lamp all is provided with radiator.The aluminium inserts is one of radiating element of using always, power supply also often is set in the aluminium inserts of hollow, because the aluminium inserts is a conductor, thereby power supply or lead directly contact generation electric leakage or short circuit easily with the aluminium inserts, jeopardize user's life safety, also damage power supply simultaneously easily.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of power supply and aluminium inserts of making to isolate, and can effectively prevent the good structure improved low-power LED lamp of security of power supply electric leakage or short circuit.

For achieving the above object, a kind of structure improved low-power LED lamp of the present utility model comprises LED, aluminium base, radiator and lamp holder, LED is arranged on the aluminium base, aluminium base is fixed in the radiator top, and lamp holder is electrically connected with LED, comprises that also the power supply of hollow is put post.

Wherein, power supply is put the post bottom and is provided with connecting portion, and connecting portion is connected with lamp holder, radiator respectively.

Wherein, power supply storing post is that the power supply that plastics are made is put post.

Wherein, radiator comprises the aluminium inserts and the heat-dissipating casing of hollow, and power supply is put post and stretched in the aluminium inserts of hollow; The aluminium inserts comprises end face and side, and heat-dissipating casing is coated on the outside of the side of aluminium inserts, and the end face of aluminium inserts is provided with fixing hole and cable-through hole.

Wherein, heat-dissipating casing is a plastic casing, and the heat-dissipating casing lateral surface is provided with radiating fin.

Wherein, the top that power supply is put post is provided with installing hole, and aluminium base is provided with fixing hole, and power supply is put capital end and aluminium inserts end face and aluminium base and is spirally connected by installing hole and fixing hole.

Wherein, also comprise lampshade, the top socket of lampshade and heat-dissipating casing.

The beneficial effects of the utility model are: the power supply that is provided with insulation is put post; power supply and aluminium inserts are kept apart; power supply or lead directly do not contact with the aluminium inserts that can conduct electricity, and prevent power supply electric leakage or short circuit effectively, thereby protect power supply and user better.
