La présente invention porte sur une lampe à DEL qui possède une structure de dissipation thermique dans laquelle des tubes de DEL en forme de barre ayant des dissipateurs thermiques couplés à ceux-ci sont couplés à des ailettes de dissipation thermique respectives d'un dissipateur thermique central, qui font saillie radialement depuis la surface périphérique externe d'un corps creux cylindrique dudit dissipateur thermique central, afin d'être disposés dans la forme d'un pilier d'une bobine, sur lesquels un fil d'un cerf-volant est enroulé, tout en formant des espaces pour une dissipation thermique entre lesdites ailettes à un intervalle prédéterminé, et la longueur du dissipateur thermique central est restreinte pour être plus petite par rapport à celles des tubes de DEL, moyennant quoi l'espace interne de la lampe à DEL est ouvert à travers les espaces pour une dissipation thermique dans toutes les directions de telle sorte qu'un espace pour faciliter la convection d'air est assuré afin de rendre maximale la convection d'air quelle que soit la position d'installation de la lampe à DEL. La présente invention peut rendre maximale une dissipation thermique puisque l'espace interne de la lampe à DEL, où une chaleur générée lorsque les tubes de DEL et des DEL sur un substrat inférieur émettent une lumière est libérée à travers la pluralité de dissipateurs thermiques en forme de barre, le dissipateur thermique central, et des dissipateurs thermiques supérieur et inférieur, est ouvert dans toutes les directions pour faciliter la convection d'air. En particulier, la présente invention peut rendre maximale une dissipation thermique quelle que soit la position d'installation de la lampe à DEL à travers la structure de dissipation thermique dans laquelle les espaces pour une dissipation thermique, formés entre les tubes de DEL, et l'espace interne de la lampe à DEL communiquent les uns avec les autres.
