Problems solved by technology

The emergence of white light LED just makes up for the shortage of the above light sources, and with the maturity of LED white light technology, more and more LED lamps are made of lighting fixtures using it as a light source, with various varieties and styles, and most of them use metal as heat sink , the light source is multiple LEDs, the cost is high, the production process is more complicated, and the light efficiency is not very high, so it is difficult to fully promote it. Therefore, it is necessary to continuously improve the existing LED lamps to achieve a simpler production and lower cost. , safer and more reliable, higher light efficiency, more beautiful, easier to promote practical high-power LED bulbs to replace traditional lamps

Embodiment Construction

[0017] Such as figure 1 , figure 2 , image 3 , a high-power LED light bulb shown, including a joint 6 for connecting with the lighting fixture interface, an LED constant current drive device 5, a radiator 4, an LED light source 2, a bulb cover 1 and a circuit board 3. The joint 6 has a cavity, and its lower end has a thick thread 6-1, the LED constant current driving device 5 is fixed in the cavity, and can be matched with a conventional lamp interface. The connector 6 is preferably molded at one time by ceramic mold opening, which not only insulates, but also has good heat conduction and heat dissipation effects, and can protect the constant current drive device 5. In addition, materials such as nylon and ABS can also be selected, but the effect is inferior. Radiator 4 is a ceramic radiator with annular fins 4-1, with threading holes inside, and a cavity matching joint 6 at its lower part, which is also used to place constant current drive device 5, the upper part of joi...

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a high-power LED light bulb. Background technique [0002] Traditional light sources are mainly incandescent lamps, energy-saving lamps, halogen lamps, and sodium lamps. These bulbs are low in cost and high in brightness, and have been widely used for a long time. However, these bulbs generally have the defects of low light efficiency and short life. During work, accidents such as fires and burns are often caused by excessive temperature; at the same time, energy-saving lamps and other gas discharge lamps contain harmful substances such as mercury and cadmium. Pollution and personal injury are caused, which is not conducive to environmental protection. Therefore, people have been pursuing a new type of lighting fixture with higher luminous efficiency, energy saving, low temperature during operation, environmental protection, safety and reliability. The emergence of white light LED just mak...
