Technical field

The utility model belongs to the LED lighting technical field, relates to a kind of high-powered LED lamp.

Background technology

Along with the continuous aggravation of global energy shortage and environmental pollution, energy-conservation and environmental protection has become the problem that society is paid close attention to most, is also the problem that must solve.In recent years, the cost of LED lamp for illumination, aspect of performance has had very large improvement, with conventional light source, compares, and the LED lighting has the advantages such as life-span length, sound construction, energy-conserving and environment-protective, for environment and the saving energy, has great importance.In current product, due to great power LED low-voltage and high-current characteristic, on the LED light fixture, all must there be enough heat sink materials to reach enough large and air contact-making surfaces, use the LED lamp of aluminium alloy and aluminium oxide ceramics heat radiation at present, with traditional lamp, compare, be all area of dissipation much larger than light-emitting area, this feature has a strong impact on installing and using of light fixture and attractive in appearance, increasing Air Flow, to make the less weight of area of dissipation be gentlier the pith of follow-up popularization and application in the LED field of lamp illumination.

The utility model content

The purpose of this utility model is to provide a kind of new high-powered LED lamp, poor with high-powered LED lamp radiating effect in the solution prior art, and the problem that volume is excessive, quality lays particular stress on, in the situation that guarantee to provide LED chip enough to dispel the heat, make the heat radiation volume of LED can accomplish minimum, make this lamp in the situation that safer, the replaceable place that is arranged on any same brightness incandescent lamp and electricity-saving lamp.

For achieving the above object, the utility model adopts following technical scheme:

The utility model high-powered LED lamp comprises the upper cover that has centre bore, solid lens, the Light-Emitting Diode pressing plate, Light-Emitting Diode, graphite flake, radiator, the vibration eardrum, the indent bonnet, driving power and standard interface assembly, described graphite flake closely is placed on the burnishing surface of described radiator, described Light-Emitting Diode closely is placed on graphite flake, the Light-Emitting Diode pressing plate closely is placed on Light-Emitting Diode, solid lens closely are placed on the Light-Emitting Diode pressing plate, described upper cover closely is placed on solid lens and solid lens pass the centre bore of described upper cover, described upper cover closely is fixedly connected with the burnishing surface of radiator, the vibration eardrum is placed in the centre bore of described radiator and the vibration eardrum is fixedly connected with radiator, the indent bonnet is fixedly connected with and vibrates with radiator in the inner concave that eardrum is placed in the indent bonnet, the standard interface assembly closely is fixedly connected with the indent bonnet and forms a cavity volume at indent bonnet and standard interface assembly, and described driving power is placed in this cavity volume and engaged fixing.

Compared with prior art, the beneficial effects of the utility model are: (1) Light-Emitting Diode and vibration eardrum can conduct to heat described radiator heat radiation fast, greatly reduce the temperature of radiator, reduce the luminescent lifetime of light decay phenomenon, raising light efficiency and described Light-Emitting Diode fully.(2) heat that light emitting diode produces becomes the move in circles device (soaking plate) of work of gaseous state by liquid state and is transmitted to uniformly on the highly heat-conductive material graphite flake of combining closely and is delivered on radiator and dissipates fast, the vibration eardrum makes the air rapid flow by generation of vibration wind simultaneously, the heat energy of air dissipation towards periphery, reduce the temperature of radiator, the assurance normal time of Light-Emitting Diode works under an allowable temperature.(3) owing to having adopted the vibration eardrum to participate in the scheme of heat radiation, make the radiator portion of lamp radiator reduce, the lighter .(4 of radiator of relative large volume) the utility model is except radiator and standard interface part, with the circuit contact site, be all to insulate with high insulated plastic glue material, eliminated the radiator required voltage, dependence to the isolation of power supply circuits high-low pressure, be arranged on various application scenarios safer, the processing of high insulation plastic cement is more convenient, make its outward appearance more attractive in appearance, processing technology is simpler and radiating effect is better, the longer service life of Light-Emitting Diode.
