Abstract
The utility model relates to a ceramic substrate, in particular to a ceramic substrate for LED lamps, which belongs to a component in an LED lamp. The existing capsulation substrate used in LED lamps has the shortcomings that 1, after being filled with insulation materials, the capsulation substrate is poor in thermal conductivity and not favorable for heat dissipation and service lives of the LED lamps are shortened; and 2, only the insulation materials are filled between an aluminum base and a circuit board, and then overall high-pressure resistance of the capsulation substrate is poor. The ceramic substrate for LED lamps is characterized in that the ceramic substrate comprises a ceramic base, a cylindrical mounting cavity is disposed in the ceramic base, and the bottom of the mounting cavity is provided with two cylindrical threading through holes. The ceramic substrate is reasonable in structural design, low in production cost and fine in heat conductivity, can resist high pressure and can enhance overall performance of LED lamps.
Description
Technical field
The utility model relates to a kind of ceramic substrate, especially relates to a kind of ceramic substrate of the LED of being used for lamp, belongs to parts in the LED lamp.
Background technology
The base plate for packaging that is used for the LED lamp at present adopts the metal aluminium to form as main material manufacturing usually, fill insulant between aluminium base and the circuit board, there is following shortcoming in this class base plate for packaging: 1, behind the fill insulant, heat conductivility is poor, be unfavorable for heat radiation, shortened the useful life of LED lamp; 2, fill insulant only between aluminium base and the circuit board causes whole high-voltage resistance capability poor.
Because the base plate for packaging that is used for high-powered LED lamp has bigger influence to the performance of LED lamp, such as the thermal conductivity of this base plate for packaging, high-voltage resistance capability to the quality of LED lamp and great influence is all arranged useful life, along with the continuous popularization of little, the high-power LED lamp of volume, existing aluminium base can not satisfy the development need of LED lamp at present.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and production cost is low, and good heat conductivity can promote the ceramic substrate that is used for the LED lamp of LED lamp overall performance.
The technical scheme in the invention for solving the above technical problem is: these characteristics that are used for the ceramic substrate of LED lamp are: comprise base of ceramic, be provided with a columned installation cavity in the described base of ceramic, the bottom of this installation cavity is provided with two threading via holes, and the shape of described threading via hole is cylindrical.
Base of ceramic described in the utility model is the cermet material.
The bottom surface of threading via hole described in the utility model and base of ceramic is perpendicular.
The utility model compared with prior art has the following advantages and effect: good heat conductivity, be beneficial to heat radiation, and can effectively prolong the useful life of LED lamp; High-voltage resistance capability is strong, can effectively promote the overall performance of LED lamp, especially can effectively promote the overall performance of high-powered LED lamp.
Of the present utility model simple in structure, reasonable in design, manufacturing process is simple, and production cost is low, can be high pressure resistant, and heat conduction and good heat dissipation effect, the LED lamp can meet the requirement of CE authentication.
