Ball bulb

A light bulb, especially a bulb.

Light sources are indispensable for daily life. Generally, indoor fluorescent lamps, table lamps, outdoor lighting, etc. must be illuminated by light bulbs.

Light emitting diodes (LEDs) have the advantages of small component size, high brightness, power saving, environmental protection, long service life, etc. In recent years, LEDs have been widely used, including traffic signs, backlights of liquid crystal displays. Modules and lighting fixtures that replace traditional bulbs in typical fixtures.

One of the performance standards of a light-emitting diode illumination device is that the light output can maintain relatively uniform color and brightness in different regions. However, the LED light source has its projection range, and the light path is gradually expanded outwardly from the base body. As a whole of the illumination device, if the LED is arranged due to the limitation of the space and the arrangement position, the light source emitted by the illumination device often generates a dark area, for example, a non-overlapping area is formed between the LED and the LED projection area. Therefore, the projected light source cannot be illuminated all the way, so that the projection brightness is lowered.

Therefore, how to solve the problem that the conventional lighting device generates a dark area that cannot project a light source is a problem that the relevant industry must consider.

In view of the above problems, this creation provides a ball bulb to solve The problem of the dark area generated by the aforementioned lighting device is determined.
