MULTI-STAGE ADJUSTABLE TELESCOPIC LAMP
Document Type and Number:
WIPO Patent Application WO/2024/016218
Kind Code:
A1
Abstract:
A multi-stage adjustable telescopic lamp, comprising a screw-type lamp holder (1), a first telescopic sleeve (2), a second telescopic sleeve (3), a third telescopic sleeve (4), fixing assemblies (5), an outer frame (6), a lighting unit (7) and a lamp body (8). The bottom end of the screw-type lamp holder (1) is connected to the top end of the first telescopic sleeve (2). The first telescopic sleeve (2) is slidably sleeved with the second telescopic sleeve (3). The second telescopic sleeve (3) is slidably sleeved with the third telescopic sleeve (4). The bottom ends of the first telescopic sleeve (2) and the second telescopic sleeve (3) are respectively provided with fixing assemblies (5). The three-stage telescopic structure is arranged to solve the problem that when the telescopic lamp extends or retracts, if the depth of a suspended light fixture having an opening exceeds the maximum extension length of the telescopic lamp, replacement cannot be carried out due to limited telescopic reach.
