Omnidirectional LED bulb lamp

Abstract

The invention discloses an omnidirectional LED bulb lamp, comprising a bulb shell, an LED bead, an aluminum substrate, an aluminum pressing cover, a lamp body, a driving PCB board and a lamp holder; the bulb shell is made from high-diffusion resin and fixedly connected with the lamp body by means of a buckle structure; the LED lamp bead is fixed with the aluminum substrate by soldering tin and has an beam angle of greater than 150 degrees with the bulb shell; the PCB board is fixed in the lamp body by a clamping slot; the lamp holder is fixedly connected with the lamp body by means of a toothed knobbing structure; the bulb shell is of a pear shape or a mushroom shape; the lamp body is of a plastic aluminum-wrapped structure; the transmittance of the material of the bulb shell is less than 70%; the external layer of the plastic aluminum-wrapped structure is made of thermal conductive plastics and the internal layer is made of aluminum; the thermal conductivity coefficient of the thermal conductive plastics is more than 1W/m.K. The omnidirectional light distribution is realized by the combination of the big beam angle formed by the LED lamp bead and the bulb shell as well as the high-diffusion resin bulb shell; and meanwhile, the problem of high heating value in the LED bulb lamp is solved by using the lamp body with the plastic aluminum-wrapped structure.

Description

technical field [0001] The invention relates to an LED bulb lamp, in particular to an all-angle LED bulb lamp. Background technique [0002] As countries around the world plan to replace incandescent lamps, LED lamps, as the fourth-generation lighting source, are accelerating their penetration in various lighting fields. As the most widely used and popular type of light source, bulb lamps require high luminous flux and light distribution for full-space lighting, and at the same time must meet the lamp body dimensions of the standard limits of various markets. LED lamps designed with traditional LED bead packages are limited by the Lambertian light distribution characteristics of the LED light source, and must rely on secondary optical structure design to achieve full-space light distribution. The structure of the lamp is complex and the cost is high; The heat generation of LED is large, and the high wattage consumed by high luminous flux requires a structure with good heat ...
