Embodiment Construction
[0039] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Please refer to the attached Figure 2-6 The present invention will be described in detail in combination with examples.
[0040] Considering that the current fishing lamp has poor heat dissipation effect, the lamp is too heavy and the cost is too high, the present invention provides a high-power LED lamp with light weight and fast heat dissipation to be used as a fishing lamp. Of course, this light is not limited to use as a fishing light.
[0041] Structure of lamps and lanterns
[0042] The high-power LED lamp includes an LED lighting module and a radiator, and the LED lighting module is fixedly installed under the radiator. The heat sink includes several heat-dissipating aluminum sheets 11 , several heat-conducting copper pipes 12 and a base plate 13 . The base plate 13 is preferably die-cast or ex...

The invention discloses a manufacturing method of an LED light source module radiator and a manufacturing method of LED lighting equipment. The radiator comprises heat dissipation aluminum sheets and heat-conducting copper pipes, all of which are arranged on an aluminum substrate. The aluminum substrate is provided with transverse grooves. The heat dissipation aluminum sheets are provided with penetrating holes. The lower edges of the heat dissipation aluminum sheets are provided with gaps. The heat-conducting copper pipes are U-shaped pipes composed of upper branches and lower branches. The lower branches are suitable for being arranged in the grooves in the temperature-uniformizing substrate and transversely penetrate the gaps in the lower edges of the corresponding heat dissipation aluminum sheets. The upper branches are suitable for transversely penetrating the penetrating holes in the corresponding heat dissipation aluminum sheets. The manufacturing method of the radiator includes the steps of conducting electroless nickel-plating process on the heat dissipation aluminum sheets, the heat-conducting copper pipes and the temperature-uniformizing substrate and conducting reflow welding on the overall structure of the assembled radiator. The bonding performance of copper and aluminum is improved through electroless nickel layers formed on the surfaces of materials, and the copper and the aluminum are bonded firmly through brazing filler metal and are resistant to high temperature, high salinity, moisture and high-corrosion environments.
Description
technical field [0001] The present invention relates to the technical field of lighting, in particular, to a method for manufacturing a heat sink for an LED light source module, and a method for manufacturing corresponding LED lighting equipment. Background technique [0002] The patent zl201520208157.3 held by the applicant himself ( figure 1 (shown) uses heat-conducting copper tubes as heat-conducting parts, and is connected with the uniform temperature aluminum plate by welding instead of riveting to achieve waterproof performance. Due to the different thermal expansion coefficients between copper and aluminum, the solder joints crack after repeated switching of the lamp, resulting in damage to the lamp; the surface of the lamp is easily corroded in a humid and high-salt environment. [0003] Copper-aluminum welding is to join the copper material and the aluminum material into one body through the welding process. Because both copper and aluminum are easy-to-oxidize met...
