Description

Lamp structure

The invention relates to a lamp structure, in particular to a lamp structure, which is provided with a body, a joint member and a light-emitting member; a first thread portion is arranged on an inner circumferential surface of the joint member; and a light-emitting member is provided with a second thread portion. The first threaded portion is screwed to form the light emitting member and the coupling member.

As is known in the prior art, the conventional luminaire structure, such as U.S. Patent No. 7,144,135, is based on a body 100 having a housing 102 that is radially and has a double opening. The outer cover 102a has a conical shape, and the outer cover 102 has a larger opening at one end and a smaller opening at the other end. The larger opening end of the outer cover 102 is provided with a first opening 102a, and the body 100 is provided. There is a socket 104 which is fixedly connected to the other end of the smaller opening of the housing 102.

However, the missing structure of this conventional lamp is:

1. When the manufacturing office is shipped from the factory, the lamp holder 104 is connected to the outer cover 102, that is, the lamp holder 104 and the outer cover 102 cannot be separated, so that the overall volume of the body 10 is large. The shape of the package is sufficient to accommodate the body 10, and the body 10 has a substantially conical shape. When the body 10 is received in the package, the space inside the package The system cannot fully utilize and waste space, and the luminaire structure has a high cost of packaging materials and cannot fully utilize the The lack of space in the package, the luminaire structure has a larger package volume, that is, a large transportation cost.

2. The main illuminating system of the luminaire structure is the lamp holder 104. The lamp holder 104 is damaged after being used for a period of time. When the lamp holder 104 is damaged, the overall luminaire structure needs to be discarded, so that the outer cover 102 is wasted. 102 is essentially a metal article and has a large volume that wastes material of the outer cover 102.

In view of the lack of the above-mentioned conventional lamp structure, the inventors have been engaged in manufacturing experience of related industries for many years, and finally have a product that can solve the drawbacks of the lamp structure.

The conventional lamp structure has a larger package volume, that is, a larger transportation cost, and the lamp structure and the light-emitting member can be respectively accommodated in the first package material and the second package material, the light-emitting member and the light-emitting member The lamp structure is separately packaged in the first package material and the second package material, thereby saving the volume and cost of the package material, thereby saving the overall transportation cost.

A luminaire structure, comprising: a body, the system is provided with a receiving groove, the end of the receiving groove is provided with a first abutting edge; and a coupling member is received at the receiving groove, the combination And the first threaded portion is disposed on the inner peripheral surface of the joint, the first threaded portion is internally threaded; and a light-emitting member has a lighting effect. The illuminating member is provided with a second threaded portion, the second threaded portion is screwed with the first threaded portion, so that the illuminating member is assembled with the coupling member, and the second threaded portion is externally threaded. The light-emitting member is convexly provided with a lamp holder at one end, and the lamp holder is exposed to the outside of the body, and the lamp holder is a standard Specification seat.

The second threaded portion of the illuminating member can be unscrewed from the first threaded portion, that is, the illuminating member is taken out from the body to replace another illuminating member, and the illuminating member and the illuminating member can be respectively accommodated in the illuminating member In the first packaging material and the second packaging material, the volume and cost of the packaging material can be saved, and the two transportations can be separately transported to save the overall transportation cost.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
