Le boîtier comprend un boîtier inférieur (10) et un boîtier supérieur (102), une carte rayonnante est disposée entre le boîtier inférieur et le boîtier supérieur, et des orifices rayonnants sont formés dans la carte rayonnante. L'élément rayonnant comprend une surface d'extrémité avant et des ailettes rayonnantes. Les ailettes rayonnantes sont disposées sur la surface d'extrémité avant. Une rainure de ventilation s'étendant vers la gauche et la droite est formée entre des ailettes rayonnantes adjacentes. Des orifices de sortie d'air de la rainure de ventilation sont en regard des orifices rayonnants. Un ventilateur est disposé sur l'élément rayonnant. Une barrière photo-électrique est disposée sur le côté intérieur de la carte rayonnante, et un espace est formé entre la carte rayonnante et la barrière photo-électrique. Un procédé de rayonnement du système selon l'invention comprend : la génération de chaleur par une source de lumière à DEL et la transmission de la chaleur dans un élément rayonnant, et dans le même temps, grâce au fonctionnement du ventilateur et à l'entrée d'air froid extérieur dans l'élément rayonnant, l'exécution d'un échange de chaleur sur l'air froid dans l'élément rayonnant, l'air chauffé étant changé en air chaud, et l'air chaud étant rayonné depuis les orifices rayonnants. Le système de rayonnement selon l'invention peut éviter l'influence des courants venteux sur la qualité des faisceaux de lumière et améliorer le taux d'utilisation de la lumière.
