Abstract

L'invention concerne une lampe d'éclairage à LED comprenant un culot de lampe standard (1), un dissipateur de chaleur (2), une source de lumière à LED (3) et un globe de lampe (4) qui couvre la source de lumière à LED. Le dissipateur de chaleur (2) est placé derrière le globe de lampe (4). La source de lumière à LED (3) est placée sur le dissipateur de chaleur (2). Des ailettes (21) sont placées autour du dissipateur de chaleur (2). Des cavités de ventilation (22) sont formées de manière adjacente aux ailettes (21). À l'extérieur des ailettes (21), un boîtier de fond (5) recouvre le dissipateur de chaleur (2) par l'arrière de celui-ci. Des orifices de ventilation (51) correspondant aux cavités de ventilation (22) du dissipateur de chaleur (2) sont placés à l'arrière du boîtier de fond (5). Le culot de lampe standard (1) est fixé à demeure à l'extrémité du boîtier de fond. Lorsque la lampe est allumée, la chaleur absorbée par le dissipateur de chaleur peut être isolée par le boîtier de fond (5), de sorte que l'extérieur de la lampe ne soit pas chaud. L'utilisateur peut facilement utiliser la lampe. Lorsque la lampe est allumée, de l'air peut passer à travers les canaux de ventilation qui sont formés par les cavités de ventilation et les orifices de ventilation. La chaleur des ailettes du dissipateur de chaleur peut être évacuée de la lampe et l'effet de dissipation de chaleur peut être amélioré.
