Abstract
The utility model discloses a ceramic substrate of a high-power light emitting diode (LED). The ceramic substrate comprises a ceramic body, a line, and hollows. The line is bonded on the front of the ceramic body while multiple hollows are arranged on the entire back of the ceramic body at intervals. Heat dissipating area of the ceramic substrate is enlarged so that heat dissipating efficiency and stability of the LED are increased while service life of the LED is prolonged.
Description
Technical field
The utility model relates to a kind of ceramic substrate, more specifically to a kind of ceramic substrate of large-power light-emitting diodes.
Background technology
Light-emitting diode is with its power saving, lightly, the characteristics such as the life-span is long are used more and more vast in the electronic product field, yet the heat dissipation problem of large-power light-emitting diodes is being stranded the stability of light-emitting diode and the further raising in useful life always, along with the progress of science and technology, occurred using the light-emitting diode of ceramic substrate on the market, but the ceramic substrate body dimension that is applied in the market light-emitting diode is compared fixingly, area of dissipation is less than normal, and radiating effect is not very desirable.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of ceramic substrate that can effectively improve the large-power light-emitting diodes of radiating effect is provided.
The utility model is achieved by the following technical programs.
The ceramic substrate of the utility model large-power light-emitting diodes, comprise ceramic body, circuit, pit, described circuit is attached to the front of described ceramic body, is provided with a plurality of pits at the back side of described ceramic body, and described pit is spaced the back side that is covered with at described ceramic body.This pit can be the sphere pit, also can be the column pit, can also be the taper pit.
Effective effect of the present utility model is: in the changeless situation of overall dimensions, increased surface area, thereby improved area of dissipation, improved the radiating efficiency of light-emitting diode, improved stability and the useful life of light-emitting diode.
