Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] like image 3 As shown, a light expanding device is arranged on the upper part of the light source body for light control, and includes a light expanding head 42 and a light expanding column 41. The bottom of the expanding head 42 is used to separate the expanding head 42 from the light source body.

[0023] The through holes 5 are circumferentially distributed on the surface of the light expanding head 42 with the center of the surface of the light expanding head 42 as the center according to different radii, and the distribution density of the through holes 5 gradually decreases along the center of the light expanding head 42 to the edge of the light...

Abstract

The invention relates to a light expansion device which is arranged at the upper part of a light source body to control light. The light expansion device comprises a light expansion head and a light expansion column, wherein the light expansion head is bowl-shaped; a plurality of through holes are formed in the surface of the light expansion head; the light expansion column is arranged at the bottom of the light expansion head and is used for spacing the light expansion head and the light source body. Through the utilization of reflection of the light expansion device and the through holes in the light expansion device, large-angle light emission of a ball bulb is easily realized; besides, the light expansion device is simple in structure and easy to process.

Description

technical field [0001] In particular, the invention relates to a light expanding device and a light bulb using the light expanding device. Background technique [0002] Compared with traditional light sources, LED has many advantages, such as: long service life, low power consumption, fast response time, strong safety and reliability, high luminous purity, and environmental protection. Until 2014, the traditional 40W bulb has occupied 40% of the US lighting market. LED will gradually replace this market due to its many advantages such as high efficiency and high reliability. Generally speaking, a 5-watt LED bulb can replace a 40-watt incandescent lamp. When the LED light source is used in a bulb , due to its single-sided light-emitting characteristics, it is difficult to achieve the requirement of a light-emitting angle of more than 230°. [0003] At present, the method commonly used in the market to solve the large-angle light distribution of LED bulb lamps is to arrange ...
