Abstract
The utility model relates to the technical field of lighting, in particular to a ceramic heat radiator for an LED lamp. The ceramic heat radiator for the LED lamp is characterized by comprising a ceramic matrix and heat dissipating fins formed outside the ceramic matrix; the heat dissipating fins are made of ceramic materials; limiting platforms and clamping slots which are continuous are sequentially formed in two ends of the heat dissipating fins from outside to inside; an inclined top surface is formed on one sides, close to the clamping slots and higher than the other sides, of the limiting platforms. The description of the ceramic heat radiator for the LED lamp shows that the ceramic heat radiator for the LED lamp is made of the ceramic materials, low in manufacturing cost, good in heat dissipating performance, and capable of normally working under a high-temperature environment; the limiting platforms and the clamping slots are formed in two ends of the heat dissipating fins, assembling efficiency is greatly improved, connection of the heat radiator, a lamp cap and a power supply assembly is firm, and the service life of a lamp holder is prolonged.
Description
Technical field
The utility model relates to lighting technical field, is specifically related to a kind of ceramic heat sink for the LED lamp.
Background technology
Existing LED bulb comprises substrate, is arranged at LED lamp and power module on the substrate, and heat abstractor.The heat that produces during the illumination of LED bulb reaches heat abstractor by substrate, has heat abstractor to radiate again, so the quality of the heat dispersion of LED bulb directly influences the life-span of LED bulb.In order to improve LED bulb heat radiation effect, the radiator that has occurred multiple different structure on the market, as Granted publication number be: the disclosed LED bulb of 201120071294.9 utility model patent is characterized in that: comprise lamp holder, with the radiator of lamp holder sealing gummed, closely contact and be connected the metal substrate in the radiator and be arranged on printing opacity face shield above the radiator; Be provided with the led drive circuit plate in the described lamp holder or in the cylindrical radiator, be arranged with a plurality of LED lamps that are connected with the led drive circuit plate on the described metal substrate.The radiator of such LED lamp adopts metal materials such as aluminium, copper to make usually, and is by glue that radiator and lamp holder is bonding, not only manufacturing cost height, assembling difficulty, and also the high temperature that radiator gives off can cause glue aging, and lamp holder comes off.
The utility model content
For overcoming deficiency of the prior art, the utility model provides a kind of ceramic heat sink for the LED lamp, it is characterized in that: comprise ceramic matrix and be formed at the outer radiating fin of ceramic matrix, described radiating fin adopts ceramic material to make, the two ends ecto-entad of radiating fin is provided with consecutive limiting stand and draw-in groove successively, and described limiting stand is higher than opposite side and forms an end face that tilts near a side of draw-in groove.
Further, ceramic matrix is the tubular construction of hollow.
Further, have the through wires hole that at least one connects vertically on the ceramic matrix.
Further, have groove on the ceramic matrix, through wires hole is communicated with by groove with the hollow bulb of ceramic matrix.
Further, have four through wires holes and four through wires holes equal angles layout centered by ceramic matrix on the ceramic matrix.
Further, ceramic matrix and radiating fin one form by a firing.
This kind is used for radiator and adopts ceramic material to make to description of the present utility model as can be known by above-mentioned, and low cost of manufacture, perfect heat-dissipating can effectively guarantee still can work normally under the environment of high temperature; Be provided with limiting stand and draw-in groove at the two ends of radiating fin, improved efficiency of assembling greatly, and make radiator more firm with being connected of lamp holder, power supply module, prolong the service life of lamp socket.

The specific embodiment
Below the utility model will be further described by the specific embodiment.
With reference to Fig. 1, shown in Figure 2, a kind of ceramic heat sink for the LED lamp comprises ceramic matrix 1 and the radiating fin 2 that is formed at outside the ceramic matrix 1.Ceramic matrix 11 is the tubular construction of hollow, axially has 11, four through wires hole 11 equal angles layouts of through wires hole of four perforations centered by ceramic matrix 1, along axle ceramic matrix 1; Have the groove 12 that through wires hole 11 is communicated with the hollow bulb of ceramic matrix 1 on the ceramic matrix 1.Radiating fin 2 adopts ceramic material to make, form by a firing with ceramic matrix 11 one, the two ends ecto-entad of radiating fin 2 is provided with consecutive limiting stand 21 and draw-in groove 22 successively, and described limiting stand 21 is higher than opposite side and forms an end face 211 that tilts near a side of draw-in groove 22.
With reference to shown in Figure 3, be the LED lamp that adopts this kind ceramic heat sink 1 to make, comprise ceramic matrix 1, radiating fin 2, lampshade 3, power supply module 4 and lamp holder 5, lampshade 3 and power supply module 4 inboards are equipped with the buckle suitable with draw-in groove 22.During assembling, earlier the LED module is installed on the ceramic matrix 1, the LED module is connected with power supply module 4 by through wires hole 11, and power supply module 4 is connected with lamp holder 5; The end face 211 of the buckle of lampshade 3 and power supply module 4 by limiting stand 21 enters in the draw-in groove 22 and radiating fin 2 clampings, by glue with lampshade 3 and power supply module 4 and ceramic heat sink sealing gummed.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
