This novel heat radiation structure lamp pearl not only have do not fear cold and hot impact, the heat conductivility is good, the light efficiency is strong, the good characteristics of insulating nature, can improve heat -sinking capability and the photoelectric conversion efficiency of lamp pearl moreover, increase of service life improves the packaging efficiency, has practiced thrift the cost of labor.
Description
Technical field
The utility model relates to LED field, is specifically related to a kind of radiating structure lamp pearl.
Background technology
LED is a kind of semiconductor element of luminescence, because its controllability is good, structure is simple, compact, color is pure, abundant, shock-resistant, vibration resistance, the features such as the response time is fast are acknowledged as one of high-tech product most with prospects, also work it out major contribution for energy-saving and emission-reduction and environmental protection simultaneously, that LED chip is directly pasted on substrate by adhesive or solder by one, then the encapsulation technology that wire bonding realizes electrical connection is carried out, what encapsulation scheme base in the market used substantially is all copper base, aluminium base, mirror-surface aluminum base board, ceramic substrate etc., wherein due to the long service life of ceramic substrate, the illumination effect of LED chip can be ensured, so the use of ceramic substrate is more extensive, but there is the shortcoming of installing inconvenience and poor radiation in ceramic substrate.
Utility model content
The purpose of this utility model is to provide a kind of radiating structure lamp pearl, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides a kind of technical scheme: a kind of radiating structure lamp pearl, comprise ceramic substrate, negative conductive portion, annular projection, positive conductive portion and silver coating, the front of described ceramic substrate is provided with annular projection, the zone line of annular projection is light source loading district, the upper end of the side of described annular projection is provided with positive electrode conductance portion, and the lower end of the opposite side of annular projection is provided with negative pole conductance portion, and the back side of described ceramic substrate is provided with silver coating.
Preferably, described ceramic substrate is that alundum (Al2O3) slurry makes curtain coating blank by casting machine, then carries out die-cut, binder removal, sintering processes, the aluminum oxide ceramic substrate that last printed wire pattern obtains.
Preferably, described silver coating is cooperatively interacted by complete orthohexagonal silver-plated district and incomplete orthohexagonal silver-plated district to form, and the outline of silver coating is rounded corresponding with light source loading face.
Technique effect of the present utility model and advantage: the ceramic substrate of a kind of radiating structure lamp pearl makes curtain coating blank by alundum (Al2O3) slurry by casting machine, then carry out die-cut, binder removal, sintering processes, the aluminum oxide ceramic substrate that last printed wire pattern gained arrives, adopt aluminum oxide ceramic substrate, the light that area source supporting region is sent is softer, and aluminum oxide ceramic substrate does not only fear thermal shock, and there is good heat conductivity, light efficiency is strong, the feature of good insulating, can by the detection of European Union's safety, the back side of ceramic substrate is provided with silver coating, silver coating is by the silver coating formed that cooperatively interacts with incomplete orthohexagonal silver-plated district in complete orthohexagonal silver-plated district, the outline of silver coating is rounded, corresponding with light source loading face, silver-plated heat-sinking capability and the photoelectric conversion efficiency that not only can improve lamp pearl at the back side of ceramic substrate, increase the service life, and silver coating can weld with substrate, facilitate the assembling of LED, improve packaging efficiency, save cost of labor, certainly, except ceramic substrate can solve heat dissipation problem by the silver-plated technology in the back side, copper base, aluminium base can adapt to this technology too and go to solve heat dissipation problem.
