LED illuminating lamp with bud bulb

Abstract

The invention discloses an LED illuminating lamp with a bud bulb, which comprises the bulb, an inner lampshade shell and light source integration modules, wherein the bulb comprises a lamp shell and a light-transmission lampshade, and the inner lampshade shell is positioned in the bulb. The inner lampshade shell is an inverted polygonal frustum with a vent hole on the lower end face, conical surfaces of the inner lampshade shell are arrayed in the light-transmission lampshade in a distributed manner, and a light source hole is arranged on each conical surface of the inner lampshade shell. An air inlet corresponding to the inner lampshade shell is arranged on the lower portion of the light-transmission lampshade, so that a through pneumatic convection channel is formed between the air inlet and an air outlet arranged on the lamp shell. The number of the light source integration modules is the same as that of the conical surfaces of the inner lampshade shell, and each light source integration module is mounted on the corresponding conical surface of the inner lampshade shell in such manner than an LED light source is embedded into each light source hole of the inner lampshade shell and a plurality of radiating fins are positioned on the inner side of the conical surface, so that the direction of radiating slots formed among the radiating fins on each light source integration module is the same as that of the pneumatic convection channel.

Description

technical field [0001] The invention relates to a semiconductor LED general lighting product in the field of energy saving and environmental protection, in particular to an LED lighting lamp with a flower bud spherical bulb. Background technique [0002] Semiconductor LED lighting has excellent performance in energy saving and environmental protection, and has wide application prospects. As a solid-state light source, it will completely replace incandescent lamps and fluorescent energy-saving lamps and become the mainstream product of the new generation of green lighting. [0003] At present, the electro-optical conversion efficiency of semiconductor LED lighting has been raised to an unprecedented level. The luminous efficacy of LED light sources exceeds 130 lumens / watt, and the overall luminous efficacy of LED lighting products can also reach about 100 lumens / watt. Even so, in the electro-optic conversion process of LED, more than half of the energy is still consumed in th...

Problems solved by technology

[0005] In addition, in the current LED lighting products, because the LED devices are mostly arranged in a centralized plane, the beam scattering angle of the LED light source cannot be enlarged, so that the beam scattering angle of the LED light source can only be limited to 90°~120°, which limits its versatility. , so it cannot meet the various needs of the lighting source
