glass heat sink for led light

Abstract

The invention discloses a glass heat sink for an LED lamp. The glass heat sink comprises a glass member, wherein the glass member comprises a cylindrical tubular connection portion; an external thread tooth is arranged on the cylindrical tubular connection portion; a glass cone heat sink is connected to the bottom end surface of the cylindrical tubular connection portion; the diameter of the bottom end surface of the glass cone heat sink is greater than the outer diameter of the cylindrical connection portion; the cone glass heat sink can be divided into an outer cone glass heat sink and an inner cone glass heat sink in structure of function; the plane of the inner cone glass heat sink is level, the corresponding surface thereof is a regular arc surface, and a through hole is formed in the centre; the cylindrical tubular connection portion is provided with one indented point or two 180-degree symmetrical indented points at the portion connected with the glass cone heat sink; the glass member is formed by heating a boron material or a sodium-calcium material and then pressing. The glass heat sink provided by the invention effectively solves the heat dissipation problem of the LED chip, and is capable of reducing or avoiding use of precious metal materials, thus greatly reducing the manufacturing cost of an LED lamp.

Description

[0001] Technical field: [0002] The invention relates to the electrical field, in particular to a lighting element, in particular to a glass heat sink for an LED lamp. [0003] Background technique: [0004] Light-emitting diodes, or LEDs, are used in general lighting products. At present, they have generally obtained more than 50% higher luminous efficacy than energy-saving lamps, and further increase. The trend of LED replacing incandescent lamps and energy-saving lamps has become a conclusion and is irreversible. In the prior art, the heat sink of the LED lamp is generally made of aluminum alloy material with good texture. According to statistics, when incandescent lamps consume copper, nickel, aluminum and other precious metals with a coefficient of 1, energy-saving lamps consume precious metals with a coefficient of about 2 to 3, and LED lamps consume precious metals with a coefficient as high as 5 to 6. 1. Packaging LED chips also requires rare and precious metals such ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a glass heat sink for LED lamps. The glass heat sink for LED lamps should solve the technical problem that LED lamps consume more precious metal materials in the prior art.
