[0002] Existing LED street light modules mostly use SMD light sources. In order to improve user experience, dual color temperature function is mostly used, that is, two circuits are arranged on the aluminum-based PCB, one is a low color temperature light source, and the other is a high color temperature light source. The color temperature is variable by adjusting the current of these two circuits, thereby improving the comfort of its lighting. This type of light source is generally large in size, and each light source has an independent PC optical lens package to achieve street light lighting. The light source is first welded on the aluminum-based PCB, and then attached to the profile radiator, and finally the PC material lens is attached to the upper part of the PCB. Due to the small and dense space, its heat dissipation area is limited and the heat dissipation efficiency is poor, so that the power of its single module is forced to be reduced to avoid overheating damage, and the lighting intensity is limited. In addition, most of the street lights nowadays are fixed lighting, and the lighting angle is fixed after installation and cannot be adjusted freely, and the applicability is poor.
