Telescopic lamp shell structure and LED ceiling lamp with same

Abstract

Disclosed is a telescopic lamp shell structure. The telescopic lamp shell structure comprises two main bottom shells, an auxiliary bottom shell, two end covers, two basic radiating boards, two movable radiating boards, at least one adjusting base and a light permeable film assembly. Each main bottom shell is provided with a containing groove and a limiting portion. The two ends of the auxiliary bottom shell are contained in the containing grooves in the two main bottom shells in a slidable mode, and the auxiliary bottom shell is provided with matching portions matched with the limiting portions. The two end covers are fixedly connected with openings in the ends of the two main bottom shells respectively. The two basic radiating boards and the two movable radiating boards are connected with the two opposite inner side faces of the two main bottom shells in a rotatable mode. One end of each movable radiating board and the end, away from the main bottom shells, of the corresponding basic radiating board are arranged in a stacked mode and connected in a slidable mode. The adjusting base is connected between at least one end cover and one ends of the two basic radiating boards or / and the two movable radiating boards. The light permeable film assembly comprises a flexible light permeable film capable of being stretched and retracted after being stressed. The telescopic lamp shell structure is convenient to carry and has various light distribution effects. The invention further provides an LED ceiling lamp with the telescopic lamp shell structure.

Description

【Technical field】 [0001] The invention relates to a housing structure of a lamp, in particular to a retractable lamp housing structure and an LED dome light using the retractable lamp housing structure. 【Background technique】 [0002] The lamp housing structure of existing lighting fixtures generally cannot be stretched or stretched only in the lamp housing with a fixed length, and the length and volume of the lamp itself cannot be adjusted after the design is fixed. Therefore above-mentioned light fixture has inconvenience in portable use field more. At the same time, the existing lamps generally fix the light source in the lamp housing, which can only provide a predetermined light distribution effect, and cannot adjust the light emitting angle of the lamp in real time in the use occasion, and cannot meet the use occasions that require multiple light output effects. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a retractable l...

AI Technical Summary

Problems solved by technology

[0002] The lamp housing structure of the existing lighting fixtures generally cannot be stretched or stretched only in the lamp housing with a fixed length. The length and volume of the lamp itself are fixed by design and cannot be adjusted later.

Therefore above-mentioned lamps and lanterns have many inconveniences in the field of portable use

At the same time, the existing lamps generally fix the light source in the lamp housing, which can only provide a predetermined light distribution effect, and cannot adjust the light output angle of the lamp in real time in the use occasion, and cannot meet the use occasions that require multiple light output effects.
