Technical Field
[0001] This utility model relates to the field of lighting fixtures, specifically to a rechargeable bulb lamp. Background Technology
[0002] LED bulbs are a new type of energy-saving lighting fixture that replaces traditional incandescent bulbs. Currently, most rechargeable LED bulbs on the market are installed with screws, making battery replacement troublesome. Without tools, it is impossible to replace the batteries, causing great inconvenience to users. Existing LED bulbs have certain drawbacks in use. First, they are inconvenient to carry: existing LED bulbs can only be powered on and emit light when installed in a lamp holder. When they need to be used in other locations, they need to use other portable lighting equipment, which not only affects the convenience of using LED bulbs, but also makes them unusable in the event of a sudden power outage. Therefore, we propose a rechargeable LED bulb. Utility Model Content
