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, a basic radiating board, a movable radiating board and a light permeable film assembly. A containing groove is formed in the end face of each main bottom shell, wherein a limiting portion is arranged at the position, close to the open end of the containing groove, of the main bottom shell. The two ends of the auxiliary bottom shell are contained in the containing grooves in the two main bottom shells, and matching portions matched with the limiting portions are arranged at the end of the auxiliary bottom shell. One end of the basic radiating board is fixedly connected with one main bottom shell, and the basic radiating board is used for bearing a first light source assembly. One end of the movable radiating board is fixedly connected with the other main bottom shell, the other end of the movable radiating board is in slidable connection with the basic radiating board, and the movable radiating board is used for bearing a second light source assembly. The light permeable film assembly comprises a flexible light permeable film capable of stretched or contracted after being stressed. The telescopic lamp shell structure can be packaged in the retraction state, the packaging space, the packaging cost and single lamp conveying cost are saved, and the telescopic lamp shell structure is convenient to carry and capable of being applicable to different using occasions. 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. Moreover, the light source structure of existing lighting fixtures is difficult to change with the outer dimensions of the lamp housing structure, and it is difficult to apply to different usage occasions. the irradiation intensity. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a retractable lamp housing structure that is easy to carry and applicable to different occasions.

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

Moreover, the light source structure of existing lighting fixtures is difficult to change with the outer dimensions of the lamp housing structure, and it is difficult to apply to different usage occasions. The intensity of irradiation
