Abstract

La tecnología de la presente invención proporciona un dispositivo de iluminación en el cual es menos probable que se produzca brillantez irregular. La unidad 12 de retroiluminación incluye un tablero 18 de LED sobre el cual se monta un LED 17 como la fuente de iluminación, un chasis 14 que incluye una placa 14a inferior colocada en un lado del LED 17 que está opuesto al lado de salida de luz y un sujetador 20 de tablero de LED fijo a la placa 14a inferior de manera que el tablero 18 de LED está interpuesto entre el sujetador 20 de tablero de LED y la placa 14a inferior. El LED 17 está distribuido de manera que la placa 14a inferior del chasis 14 incluye por lo menos un área LA de distribución del LED 17 y por lo menos un área LN sin distribución del LED 17. El sujetador 20 de tablero de LED incluye una porción 22 para dirigir luz que sobresale hacia el lado de salida de luz que está opuesto al lado del tablero 18 de LED y que dirige la luz hacia el lado de salida de luz.
