Background technology
LED is meant light emitting diode, and led light source is because long service life, the energy consumption of LED lamp are low, energy savings is remarkable as a kind of development new type light source rapidly; Therefore the LED lamp has been widely used in the daily life as light source, like LED bulb lamp, shot-light; Down lamp etc., however LED is as light source; Usually all need to work constantly for a long time, even if for this cold light source of LED, work also can produce the great amount of heat accumulation for a long time; Along with the LED bulb lamp market demand increases and the raising of power and brightness, the inner heat that produces is assembled significantly to raise and is directed at the light source quick aging, decay when making the work of LED bulb lamp.Therefore; The radiating effect that how to improve the LED bulb lamp becomes key issue in the LED bulb lamp technology, and in the prior art, and the LED bulb lamp is made up of substrate, the LED lamp pearl, power module, the heat abstractor that are arranged on the substrate basically; When the operating illumination of LED bulb lamp; The heat that is produced reaches heat abstractor through substrate, goes out via the heat abstractor heat loss through radiation again, but because the heat loss through radiation area of heat abstractor is limited; Cause radiating effect not good, thereby influence the service life of LED bulb lamp.
The utility model content
The utility model provides a kind of LED bulb lamp, to solve the bad problem of present LED bulb lamp heat radiation.
For realizing above-mentioned purpose, adopt following technical scheme:
The distinguished and admirable bulb lamp of a kind of LED comprises lamp holder and lamp body and heat abstractor, and light source board and lampshade are installed on the said lamp body, and the one side of said light source board is equipped with LED lamp pearl, and another side is equipped with support, is fixed with power module on the said support; Said heat abstractor comprises radiator; Said radiator is fixedly mounted on the lamp body and with lamp holder and is fastenedly connected; Power line on the said lamp holder is connected with power module on being installed in support, heat radiation airflow channel and outer heat radiation airflow channel in said heat abstractor also comprises, said in the heat radiation airflow channel be provided with air intake passage and air-out passage; Said air intake passage is the lampshade that is provided with air inlet b, and said air-out passage is the ventilation slot that is provided with on the radiator; Said outer heat radiation airflow channel is made up of the distinguished and admirable outer cover that is installed on the distinguished and admirable bulb lamp of LED, and said distinguished and admirable outer cover has and can the distinguished and admirable bulb lamp of LED be placed its inner cavity, and distinguished and admirable outer cover is provided with air inlet a and air outlet.
Especially, said ventilation slot places in the adjacent zone of radiator and the lamp holder of inner hole shape for hollow structure, along the radiator circle distribution, ringwise.
Especially, the air outlet that is provided with on the said distinguished and admirable outer cover is positioned at the top of distinguished and admirable outer cover, and the air inlet a of said distinguished and admirable outer cover is the space that forms between distinguished and admirable outer cover and the distinguished and admirable bulb lamp of LED that is installed in its internal cavities.
Especially, said air intake passage is that the lampshade that is provided with air inlet b forms with the lamp body that is provided with through hole, light source board installation and combination.
The beneficial effect of the utility model is: because heat abstractor also comprises interior heat radiation airflow channel and outer heat radiation airflow channel; The inside of said radiator is the hole shape of hollow structure, and gas is met heat and had flowability upwards, forms cross-ventilation; The heat that produces when therefore bulb lamp is worked can rise in through hole from lower to upper; Flow out from the air-out passage, thereby quickened the heat radiation of LED bulb lamp, indirect raising the service life of LED bulb lamp; Again because distinguished and admirable outer cover is installed on the distinguished and admirable bulb lamp of LED; Said distinguished and admirable outer cover can place the distinguished and admirable bulb lamp of LED in its cavity; Said distinguished and admirable outer cover is provided with air inlet a and air outlet, thereby constitutes outer heat radiation airflow channel, forms in the outside of interior heat radiation airflow channel once more and pulls out wind scorpion; Accelerated flowing of heat more, made the LED bulb lamp have longer service life.
