Abstract

The invention discloses a fabrication method of an integrated 360-degree three-dimensional luminous light source with a power supply and proposes an integrated 360-degree three-dimensional luminous lamp with a power supply on the basis of the process. The integrated 360-degree three-dimensional luminous lamp comprises a substrate with a conductive circuit, a capacitor, a power tube, a bridge stack, an IC intelligent chip and an LED chip, wherein the mentioned devices are covered by employing resin hybrid fluorescent powder on a front surface and a back surface of the substrate, heat-dissipation protection glue is wrapped, an LED three-dimensional light source for G9 can be fabricated, and meanwhile, and an ED bulb lamp, an LED crystal lamp or an LED Christmas lamp also can be fabricated. Gold deposition or silver plating is performed on a surface of an exposed chip bonding pad, an LED inverted chip employs a eutectic soldering mode, a mode of integral wrapping by the resin hybrid fluorescent powder is employed, so that the substrate, the LED chip and a plurality of power supply modules are effectively connected to form a whole, the volume of the LED light source is reduced, meanwhile, the light source is good in heat dissipation and firm in connection, and the application range is further expanded.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a method for preparing a 360-degree three-dimensional luminous light source integrated with a power supply. Background technique [0002] Due to the characteristics of energy saving and high luminous efficiency, LED lamps are becoming more and more popular in the field of indoor and outdoor lighting, and gradually replace conventional tungsten and halogen lamps. At present, the structure of conventional LED lamps is usually large in size. The reason is that conventional LED lamps are mainly composed of light source, power supply and lamp housing. Independent structure, so the volume of the LED lamp is increased. With the increase of the volume, it has the following disadvantages. One is that the cost of the material increases greatly with the increase of the material; the other is that it is not easy to make it smaller LED lamps; limit the application occasions of LED lamps; thi...

At present, the structure of conventional LED lamps is usually large in size. The reason is that conventional LED lamps are mainly composed of light source, power supply and lamp housing. Independent structure, so the volume of the LED lamp is increased. As the volume increases, it has the following disadvantages. One is that the cost of materials increases greatly with the increase of materials; the other is that it is not easy to make a smaller volume LED lamps; limit the application occasions of LED lamps; third, the structure is prone to failure during transportation and use, thus increasing the maintenance cost of lamps

[0003] LED companies at home and abroad have also considered how to reduce the overall size of the LED light source, but a series of problems will follow after the reduction. One is the LED chip and many power supply materials such as rectifier tubes, voltage control tubes, control How to effectively and fixedly connect the flow tubes together electrically; the second is the heat dissipation problem after being connected together; the above two problems are also the obstacles that prevent the size of the LED light source from being greatly reduced
