Problems solved by technology

The disadvantage of the heat dissipation device of this structure LED lamp is that its heat dissipation is generally realized by the heat sink installed on the lamp housing or inside, and only the heat dissipation of the lamp housing part can be realized. Since the heat generation of the LED light source is 360 degrees, the front of the light source The heat is mainly concentrated in the bubble
Therefore, the heat dissipation of the bulb, especially the light source part, is actually not sufficient, and the bulb cannot achieve complete heat dissipation.
Since the outer bulb of the high-power and large-angle LED bulb is larger than a hemispherical structure, the volume that can be used for the radiator is greatly reduced, and it cannot meet the use of LED lamps with high-power and large-angle lighting.

Abstract

The invention discloses a ventilation and forced air cooling device in an LED bulb (light emitting diode). The device disclosed by the invention comprises a bulb-holder insulator, a lamp housing, a mini-fan, a bidirectional radiator, a current-limiting board, a heat-conducting pillar, a wind-conducting reflector and a lampshade, wherein the bulb-holder insulator is provided with an air vent; the lamp housing is clamped at a bulb holder; the mini-fan is arranged in the lamp housing; the bidirectional radiator is arranged between the lamp housing and the lampshade, one end of the bidirectional radiator is clamped at the lamp housing, the other end of the bidirectional radiator is matched with the lampshade, and the bidirectional radiator is provided with a through hole communicated with cavities of the lamp housing and the lampshade; the current-limiting board is arranged in the lamp housing, and is covered on the upper part of the bidirectional radiator; one end of the heat-conducting pillar is clamped at the bidirectional radiator, and the other end of the heat-conducting pillar is matched with LED light emitting components; the wind-conducting reflector is arranged in the lampshade and matched with the bidirectional radiator; and the lampshade is matched with the bidirectional radiator for positioning, and an air vent formed at the matched position of the bidirectional radiator and the lampshade is communicated with the air vent at the bulb holder so as to form an airflow channel. The device provided by the invention has the advantages that for reaching a heat-exchange control temperature, the cooling device in the LED bulb can carry out forced-air cooling on cooling fins in the bulb and cooling fins in the radiator and then discharge hot air from the airflow channel so as to meet the temperature requirement for heat exchange.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a heat dissipation device for an LED lamp, in particular to a heat dissipation device for realizing ventilation and forced air supply in a bubble. Background technique [0002] The existing LED lamps generally include a lamp base, a lamp body and a lampshade. An LED light-emitting unit is arranged inside the lampshade, and a heat dissipation device is arranged on or inside the lampshade. The disadvantage of the heat dissipation device of this structure LED lamp is that its heat dissipation is generally realized by the heat sink installed on the lamp housing or inside, and only the heat dissipation of the lamp housing part can be realized. Since the heat generation of the LED light source is 360 degrees, the front of the light source The heat is mainly concentrated in the bubble. Therefore, the heat dissipation of the bulb, especially the light source part, is actually not suf...
