Abstract

L'invention concerne une lampe à LED transparente bilatérale, comprenant un culot de lampe (10), un dissipateur thermique (20) et une plaque de lampe à LED (30). Une partie supérieure du culot de lampe (10) est munie d'un trou de transmission de lumière, un premier miroir à transmission de lumière (40) se trouvant dans le trou de transmission de lumière. Un premier trou traversant (201) se trouve sur le dissipateur thermique (20). La plaque de lampe à LED (30) comprend une plaque de base (31) et une source de lumière à LED disposée sur la plaque de base (31), un deuxième trou traversant (301) se trouvant sur la plaque de base (31). Un deuxième miroir à transmission de lumière (50) est fixé sur le culot de lampe et sa face arrière est munie d'une face réfléchissante (51). Une partie de la lumière est directement émise vers le bas à travers le deuxième miroir à transmission de lumière (501) et l'autre partie de la lumière passe à travers le deuxième trou traversant (301) et le premier trou traversant (201), après avoir été réfléchie par la face réfléchissante (51), pour être émise vers le haut depuis le premier miroir à transmission de lumière (40), réalisant ainsi une émission de lumière bilatérale. La lampe réduit les coûts, consomme peu d'énergie, dissipe facilement la chaleur et est commode à assembler.
