Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] For the LED light bulb 100 of the first embodiment of the present invention, please refer to Figure 1 to Figure 2 .

[0011] Please refer to figure 1 and figure 2 The LED bulb 100 includes a lamp body 10 , three light source bars 30 , a plurality of LED light sources 33 arranged on the light source bars 30 and a lampshade 20 covering the top of the lamp body 10 . The lampshade 20 is a transparent or translucent shell structure with a bottom opening 21 . The lampshade 20 is a bulb shell structure.

[0012] These light source bars 30 are arranged on the top of the lamp head body 10 . Each light source bar 30 is arranged near the side of the lampshade so that each light source bar 30 is away from the opposite side of the lampshade 20 respectively; The distance on the opposite side becomes longer. The front surfaces of the...

Abstract

The invention discloses an LED (Light-Emitting Diode) bulb. The LED bulb comprises a lamp holder body, light source bars and a lampshade which covers the top of the lamp holder body, wherein the lampshade is of a transparent or translucent shell structure with openings at the bottom; the light source bars are arranged on the top of the lamp holder body; the front surface of each light source bar is provided with multiple LED light sources; the light source bars are arranged close to one side of the lampshade, so that the light source bars are away from the opposite side of the lampshade; and the LED light sources shine toward the opposite side of the lampshade shell. The LED bulb has the advantages that the light mixing effect is good and the illumination uniformity is good.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an LED light bulb. Background technique [0002] LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, so their applications are becoming more and more extensive. LED lamps will gradually replace traditional lighting fixtures such as incandescent lamps and halogen lamps. At present, most of the light sources of LED bulbs that are common in the market are arranged as planar light sources and emit upwards. There is a problem that the light does not mix well in the optical cavity, which will cause the edge of the bulb to be brighter or darker. How to change the arrangement of light sources to achieve better light mixing is an important research and development direction. Contents of the invention [0003] In view of this, it is necessary to provide an LED bulb with better light mixing effect. [0004] An LED light bulb, com...
