Description

A kind of LED light

【Technical field】

The utility model relates to an LED lamp.

【Background technique】

LEDs are widely used and have entered thousands of households. However, the heat dissipation problem of LED lamps has not been well resolved. The existing LED lamp cups are all conical shells, which cannot conduct heat and are not conducive to heat dissipation. The existing lampshade and There is no direct contact between the circuit board and the LED light bulb, and the heat is transferred through the air. The heat dissipation effect is poor, and the LED light bulb and the circuit board are easy to heat up, resulting in a shortened life of the LED light and cannot be used for a long time.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies in the prior art, and to provide a durable LED lamp in which the circuit board and the lampshade are closely attached to directly conduct heat and dissipate heat.

The utility model is achieved through the following technical solutions:

An LED lamp, comprising a metal outer cover, is characterized in that the outer cover is provided with a heat conduction plate capable of conducting heat to the outer cover to dissipate heat, and the aluminum base circuit board is closely attached to the heat conduction plate, and the aluminum base An LED bulb is arranged on the circuit board, and a cone-shaped lamp cup is arranged on the outside of the LED bulb.

The above-mentioned LED lamp is characterized in that the upper end of the conical lamp cup is provided with a solid light-transmitting body, the upper part of the conical lamp cup is provided with a bulb hole, and the LED bulb extends into the bulb hole.

The above-mentioned LED lamp is characterized in that the outer cover includes an upper cover and a lower cover.

The above-mentioned LED lamp is characterized in that heat sinks are provided on the outer side of the outer cover.

The above-mentioned LED lamp is characterized in that a collar for supporting the cone-shaped lamp cup is provided at the mouth of the outer cover.

The above-mentioned LED lamp is characterized in that a battery cavity is formed between the upper cover and the lower cover, and a storage battery is installed in the battery cavity.

Compared with the prior art, the utility model has the following advantages:

The lampshade of the utility model is provided with a heat conduction plate, and the aluminum base plate is directly attached to the heat conduction plate for heat conduction and heat transfer, and the heat dissipation effect is good. The contact between the solid conical light-transmitting lamp cup and the aluminum base plate is helpful for heat dissipation, and is more conducive to ensuring good heat dissipation Effect.
