Abstract: A light-emitting diode (LED) street lamp is applicable for street lighting. The LED street lamp includes a casing, an LED module, and a heat dissipation module. The LED module and the heat dissipation module are arranged inside the casing. The LED module includes a frame, a circuit board carrying a plurality of LEDs, and a light regulation mechanism. The frame and the circuit board are set opposing each other with the light regulation mechanism arranged therebetween to interfere with emission light from the LEDs. The emission light, after being interfered with, is projected outside the casing to realize lighting. The heat dissipation module is in physical engagement with the LED module to remove heat generated by the LEDs. As such, the LED street lamp is provided with a broader range of illumination angle and more uniform brightness, so that the same LED street lamp is applicable to various sites and the heat generated by the LEDs can be efficiently dissipated.

Abstract: The display module contains a circuit board, a heat-resistant and transparent protective layer, and a transparent and waterproofing enclosing member. The circuit board has a number of LED devices configured on the front surface and at least a terminal on the back surface. The LED devices are electrically and signally wired to the terminal so that electricity and video signals are fed to the LED devices via the terminal. The protective layer is coated on the outer surfaces of the LED devices and the circuit board so as to protect the wiring, the soldering contacts, and the electrical components of the circuit board from being damaged by the high temperature during the process of forming the enclosing member. The enclosing member wraps the circuit board and the LED devices entirely within and exposes only the terminal.
