摘要： A light emitting diode (LED) support frame (10), LED device adopting the same, and LED display module. The LED support frame (10) comprises a base board (101) and a reflection cup (102). A light converging component (103) is arranged on the reflection cup (102). A concave light converging surface (1030) is provided at a side of the light converging component (103) and adjacent to a reflection cup mouth (1021). A part of a light beam emitted from an LED chip is directed to the light converging surface (1030), reflected by the light converging surface (1030), and finally converged with other light beams emitted from the LED chip to focus at a visual field observed by an observer. Therefore, the embodiment effectively reduces optical loss of lights from different directions in the light converging component (103).
