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 and a light permeable film assembly. Each main bottom shell is provided with a containing groove and a limiting portion. The bottoms of the main bottle shells are used for bearing first light source assemblies. 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. Each end cover is provided with a limiting groove. The two basic radiating boards and the two movable radiating boards are each provided with a double-screw bolt capable of penetrating through the corresponding limiting groove in a slidable mode. The double-screw bolts are connected with nuts in a screwed mode after penetrating through the limiting grooves in the end covers, so that the basic radiating boards and the movable radiating boards are fixed. 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.
