In one embodiment, the conducting strips include a positive conducting strip, a negative conducting strip and a grounding conducting strip, and the positive conducting strip, the negative conducting strip and the grounding conducting strip are separated by an insulating material, wherein the grounding conducting strip is electrically connected with the lamp box, and the positive conducting strip and the negative conducting strip are respectively electrically connected with the positive port and the negative port of the lamp panel. The data line is connected with the data port of the lamp panel. The conductive sheet is accommodated in the heat sink and fixed to a sidewall of the heat sink, for example, the conductive sheet is fixed to the sidewall of the heat sink through an insulating adhesive. In this embodiment, the notch of radiating groove has seted up the breach of stepping down, and conducting strip and data line wear to establish should stepping down breach and external connection, if the conducting strip is connected with outside power, the data line is connected with outside PLC control system. Therefore, the power-on and the on-off of each LED lamp core can be controlled, and the operation under the control is realized.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
