Constructive method of general LED (light-emitting diode) bulb, and LED bulb with fluorescent inner cover

Abstract

The invention discloses a constructive method of a general LED (light-emitting diode) bulb, and an LED bulb with a fluorescent inner cover. The constructive method comprises the steps as follows: a silver paste printed circuit is embedded on a heat conducting bracket with heat conducting fins, wherein the heat conducting bracket is molded by utilizing non-metallic heat conducting material through sintering; and then an LED chip is welded or the LED chip as well as a drive chip are welded on the silver paste printed circuit so as to construct the LED bulb; a bulb inner cover is fixed on the heat conducting bracket by means of arranging a caulking groove; the LED chip and the drive chip are coated in the bulb inner cover; a flange structure for installment is further sintered on the heat conducting bracket; fluorescent powder is coated on the inner side of the bulb inner cover; and the LED chip is only packaged by utilizing transparent silica gel. The bulb constructed by the method disclosed by the invention can work independently, so that respective independence of the LED bulb, a lamp and a lighting control product is realized in production and use, therefore, production links of LED lighting products can be greatly reduced, mass production is improved, and LED energy saving lighting products can be facilitated in industrialization.

Description

technical field [0001] The invention relates to a method for forming a general-purpose LED light bulb and an LED light bulb with a fluorescent inner cover, belonging to the technical field of LED lighting. Background technique [0002] As a new generation of lighting technology, semiconductor lighting has high photoelectric conversion rate, easy control of light source direction, easy control of lighting period and mode, high color rendering of light source, high power factor under reasonable design, etc., which cannot be compared with other existing lighting technologies. The five energy-saving advantages are favored by global investors and strongly supported by governments of various countries. The luminous efficiency of current LED lighting can exceed 70LM / W, which is more energy-saving than traditional energy-saving lamps. Theoretically, the luminous efficiency of green LEDs can be as high as 683LM / W; the theoretical efficiency of white LEDs can also reach 182.45LM / W, s...
