Abstract

The utility model provides an LED lamp bulb. The LED lamp bulb comprises a lamp base and LED lamp beads, and further comprises a heat-dissipating aluminum piece, an insulating heat-conduction plastic piece, a light-equalizing plate and a decoration ring. The insulating heat-conduction plastic piece is arranged inside the heat-dissipating aluminum piece to form an insulating heat-conduction layer. The LED lamp beads are arranged inside the insulating heat-conduction plastic piece, the light-equalizing plate is arranged on the LED lamp beads, and the lamp base is connected with the decoration ring into a whole through the heat-dissipating aluminum piece and the insulating heat-conduction plastic piece. The insulating plastic conduction piece is used in the LED lamp bulb, so that when the lamp base is used or after the lamp base is damaged, the insulating effect is achieved, and under the protection of the heat-conduction plastic piece, the phenomenon of electric leakage or short circuit cannot occur. Moreover, the LED lamp bulb is good in safety and meanwhile has heat-conduction performance and heat-dissipating performance.

Description

A kind of LED bulb

Technical field

The utility model relates to lighting field, is specifically related to a kind of LED bulb.

Background technology

Nowadays at lighting field, LED is applied very widely because of its energy-saving and emission-reduction, environmental and durable characteristics, and wherein the LED bulb is the most common.Although the LED bulb is energy-conservation, having a defect is exactly to use isolation drive, and isolation drive cost in the market is high, and efficiency is low, if with high-pressure lamp pearl plate, with metal heat sink, coordinate and can run into a lot of safety problems.

Summary of the invention

In order to address the above problem, the utility model by the following technical solutions:

A kind of LED bulb, comprise lamp holder, heat radiation aluminum component, insulating heat-conductive plastic parts, LED lamp pearl, equal tabula rasa, rosette, described insulating heat-conductive plastic parts is arranged in the heat radiation aluminum component, form thermal insulation layer, described LED lamp pearl is arranged in the insulating heat-conductive plastic parts, on described LED lamp pearl, equal tabula rasa is set, described lamp holder is connected to an integral body by dispel the heat aluminum component and insulating heat-conductive plastic parts and rosette.

The utlity model has following beneficial effect: LED lamp pearl heat is seen through insulation plastic cement heat-conducting piece be delivered in the heat radiation aluminum component, play simultaneously insulating effect, electric leakage or short circuit phenomenon can not occur, security performance is good, can use non-isolation drive, at the bottom of cost, efficiency is high, and is easy for installation.
