Description
Technical field
The utility model relates to a kind of LED light fixture, is specifically related to a kind of innovation structure design from preferable radiating effect to discharging hot gas that adopt end to reach.
Background technology
Because the made light fixture of light emitting diode (LED) has power saving more, advantage such as durable than conventional lamp, therefore the occupation rate on market has the trend that increases gradually.
But the LED light fixture is with regard to structure, for tackling its high brightness demand, the LED group is established quantity must be increased relatively, when the quantity of LED arrives certain scale, it will produce higher temperature relatively when lighting running and influence member service life and security, therefore, thermal component also just becomes one of indispensable and important structure of high-brightness LED light fixture.
In the existing LED lamp cooling structure design, simple way has, LED is mounted on the heat radiation pedestal, offer louvre so that hot gas is arranged the outside that sheds in all sides of LED lamp casing again, but the design of this kind radiator structure still belongs to passive mode, and can't force and the hot type that pedestal absorbed of will dispelling the heat effectively looses, so radiating efficiency is poor, be not sufficient to tackle the radiating requirements of high brightness, high efficiency LED light fixture.
Another kind of existing LED lamp cooling structure as shown in Figure 1, a radiator fan 12 is set up in heat radiation pedestal 11 corresponding sections at LED light fixture 10, running by this radiator fan 12 produces drive air-flow W, to force that hot gas is discharged the outside, LED light fixture 10 all sides locate then to be provided with steam vent 14 and air admission hole 15 separately; Yet still there is following problems in the existing LED lamp cooling structure of this kind:
Because the side radiating surface 13 that its heat radiation pedestal 11 is established radiator fan 10 for group is set as plane, therefore, when described radiator fan 12 rotations operate, after the air-flow W that is pushed by radiator fan 12 clashes into this radiating surface 13, will produce the side direction turnover and directly see through the set steam vent 14 of LED light fixture 10 all sides and discharge outside; Yet, because air admission hole 15 that LED light fixture 10 all sides are set and aforementioned steam vent 14 positions are quite near (generally only about 3 centimetres of spacings), therefore, will be by the thermal current W that steam vent 14 side direction are discharged easily once again by sucking in the air admission hole 15 suction LED light fixtures 10 or by these steam vent 14 side direction positions, and then form the phenomenon that thermal current W circulates repeatedly, thus, owing to be difficult to import cold air in radiator fan 10 runnings, certainly will significantly influence its radiating effect.
Again as shown in Figure 2, when light fixture (as pendent lamp) position group that LED light fixture 10 is assembled is provided with lampshade 16 LED light fixture 10 is surrounded, after making thermal current W that aforementioned existing LED light fixture 10 is produced discharge, be subjected to this lampshade 16 block resistances, cause the aggravation of thermal current W circulating phenomenon, cause its hot gas to be difficult to arrange diffusing problem more.
At the existing problem of above-mentioned existing LED lamp cooling structure, how to develop a kind of innovation structure that has more desirable practicality, looked forward to by the user in fact, also must make great efforts target and the direction that research and development break through for relevant dealer.
Therefore, the creator is in line with the manufacturing development of being engaged in Related product for many years and design experiences, at above-mentioned target, in detail after design and the scrupulous assessment, eventually this creation of a true tool practicality.
