Small electronic energy-saving bulb with three primary colors

Abstract

The invention relates to a small electronic energy-saving bulb with three primary colors. The small electronic energy-saving bulb comprises a lamp cap, a lamp tube base and a lamp tube, wherein the lamp tube base is arranged in the lamp cap and is provided with a ballast; the lamp tube is connected and fixed together with the lamp tube base; the lamp cap is electrically connected with the ballast and the lamp tube; the lamp tube is arranged in a lampshade; and the lampshade is connected and fixed together with the lamp tube base or the lamp cap. Three or four cylindrical blind holes for fixing the lamp tube are formed in the lamp tube base which is also provided with an opening for placing a rectifier bridge stack of the ballast and four openings for placing conducting wires of the lamp tube; a plurality of heat radiating holes are formed in the top end of the lamp cap; and the lamp tube is a U-shaped fluorescent lamp tube with three primary colors. The small electronic energy-saving bulb is not provided with a plastic shell, so that the volume is reduced and can be same as that of a common incandescent bulb, the length of a lamp body is reduced, and the application range is widened; the lampshade plays a relatively good role in protecting the lamp tube and guarantees more safety and reliability in use, and rays transmitting the lampshade can be made softer; and the small electronic energy-saving bulb is relatively small in volume, compact in structure, soft in rays, attractive in appearance and wide in application range.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a tri-color small electronic energy-saving light bulb with a small volume and a compact structure and a lampshade. Background technique [0002] Existing electronic energy-saving light bulbs generally include a lamp cap, a plastic casing, a lamp holder cover and a lamp tube. At present, the plastic shells used in such energy-saving light bulbs are relatively large, and generally cannot be the same size as ordinary incandescent light bulbs, such as A13 or A15 incandescent light bulbs. The existing electronic energy-saving light bulb has a large plastic shell, which also makes the lamp body longer, restricting the range of use of the electronic energy-saving light bulb. Contents of the invention [0003] In view of the shortcomings of the existing energy-saving lamps above, the purpose of the present invention is to provide a small electronic energy-saving light bulb with a small ...
