Problems solved by technology

Fluorescent light bulbs appeared after incandescent light bulbs. Although they are energy-saving and brighter, they are not environmentally friendly due to the large amount of fluorescent powder used.
At present, more energy-saving and environmentally friendly LED light sources have emerged, and LED bulbs have been produced. The existing LED bulbs are similar in structure to traditional incandescent bulbs. adjust as needed

Abstract

The invention discloses an LED bulb that is adjustable and of which the burner can be rotated at the light extraction direction, which comprises a burner (1), an insulation bottom shell (2), a driving power (3), an insulation cover (4), a central axis plate (5), a heat dissipating neck(6), a heat dissipating hemisphere (7) connected with an LED chip (12) and a light transmitting hemisphere (15). The insulation cover (4) and the insulation bottom shell (2) are fixedly connected and lead the driving power (3) to be arranged in the inner part between; the bottom part of the heat dissipating neck(6) is fixedly connected with the insulation bottom shell (2); the central axis plate (5) is fixedly connected with the heat dissipating neck(6); a vertical axis (51) is arranged on the central axis plate (5); the heat dissipating hemisphere (7) is provided with a guiding groove (71) that passes a pole and extends along the latitude line; after passing through the guiding groove (71), the vertical axis (51) is sequentially sheathed and connected with a gasket (8) and a spring (9), and then sequentially passes through a positive stop nut (10) and a locking nut (11) to positioning and connecting the heat dissipating hemisphere (7) and the heat dissipating neck(6), and the heat dissipating hemisphere (7) rotates correspondingly to the heat dissipating neck(6) by using the vertical axis (51) as a guiding axis through the guiding groove (71).

Description

technical field [0001] The invention relates to an LED light bulb. Background technique [0002] Traditional light bulbs are incandescent light bulbs with low illuminance, dim light and no energy saving. After the incandescent light bulb, the fluorescent light bulb appeared. Although it is energy-saving and bright, it is not environmentally friendly due to the large amount of fluorescent powder used. At present, more energy-saving and environmentally friendly LED light sources have emerged, and LED bulbs have been produced. The existing LED bulbs are similar in structure to traditional incandescent bulbs. Adjust as needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a rotatable LED light bulb, the light emitting direction of which can be adjusted. [0004] The technical solution adopted in the present invention is: the present invention includes a lamp cap, an...
