Description

Lamp housing

technical field

The utility model relates to a lamp housing, in particular to a lamp housing structure with light weight, low cost and more environmental protection characteristics.

Background technique

In addition to light-emitting components such as lamp tubes, bulbs or light-emitting diodes, lamps or lighting devices are often equipped with a lamp housing. Adds light source exposure to lamps or lighting fixtures.

As shown in Figure 1, it is a commonly used lamp structure in the market. In this lamp structure, the lamp housing 1 is mainly provided with a relevant optical mechanism 3 at the position corresponding to the lamp tube 2 (such as the one shown in the figure). The concave arc-shaped configuration or planar configuration, etc.) are used to improve the light irradiation effect of the lamp tube 2 .

The lamp housing 1 is mostly made of aluminum alloy and other metal materials, so that the optical mechanism 3 for improving the light irradiation effect of the lamp tube 2 can be processed by directly using the material characteristics of the lamp housing 1 itself; The shell 1 must consume more material costs, and the weight of the whole lamp shell 1 is relatively heavy.

Utility model content

In view of this, the technical problem solved by the utility model is to provide a light-weight, low-cost, and more environmentally friendly lamp housing structure.

In order to achieve the above purpose, the lamp housing of the present utility model is composed of an environmentally friendly foamed plastic structure layer and a reflective layer; wherein, the environmentally friendly foamed plastic structure layer can be recycled and combined foamed plastics, or can be biologically The decomposed foamed plastic can not only greatly increase the weight of the overall lamp housing and reduce material costs, but the environmentally friendly foamed plastic used in the environmentally friendly foamed plastic structural layer makes the overall lamp housing more environmentally friendly.

One of the effects of the present invention is that the reflective layer can be formed by punching metal plates or coated with silver, so the cost of materials can be greatly reduced.

The second effect of the utility model is that the environmentally friendly foamed plastic structure layer can be combined with the pre-processed reflective layer by using the forming mold during the forming process, so as to effectively improve the structural strength of the overall lamp housing.

The third effect of the utility model is that the raw material used to make the environmentally friendly foamed plastic structure layer can be polylactic acid fiber foamed plastic (LACTRON) made from corn, which can be decomposed into carbon dioxide and water in the soil , so it has excellent environmental protection characteristics.

The fourth effect of the utility model is that the raw material used to make the environmentally friendly foamed plastic structure layer can be recycled from PE or PP and kneaded, so it has excellent environmental protection characteristics.

The fifth effect of the utility model is that the raw material used to make the environmentally friendly foamed plastic structure layer can be fatty polyoxyethylene polyoxypropylene ether (AEP) environmentally friendly foamed plastic, so it has the characteristics of low cost and environmental protection.

Detailed ways

The features of the utility model can be clearly understood by referring to the detailed description of the drawings and the embodiments.

As shown in Figure 2, the lamp housing 10 of the present invention is composed of an environmentally friendly foamed plastic structure layer 11 and a reflective layer 12; wherein:

The environmentally friendly foamed plastic structure layer 11 is made of foamed plastics to form the main mechanical structure of the overall lamp housing 10. It can be made of recycled foamed plastics or biodegradable foamed plastics by foaming technology. During implementation, the raw materials used to make the structural layer of environmentally friendly foamed plastics can be mixed from recycled PE or PP, or fatty polyoxyethylene polyoxypropylene ether (AEP) environmentally friendly foamed plastics, or corn as raw materials The polylactic acid fiber foam plastic (LACTRON) made can not only greatly increase the weight of the overall lamp housing and reduce material costs, but also the overall lamp housing is more environmentally friendly.

As for the reflective layer 12, which is constructed on the part of the environmentally friendly foamed plastic structure layer 11 corresponding to the light-emitting component, it is mainly used to improve the light irradiation effect of the light-emitting component. As shown in Figures 3 and 4, during implementation, the reflective layer 12 can be It is stamped and formed by a metal sheet, and during the molding process of the environmentally friendly foamed plastic structure layer 11, the mold 20 is used to combine the environmentally friendly foamed plastic structure layer 11 with the pre-processed reflective layer 12, so that the overall lamp can be effectively improved. The structural strength of the shell; of course, the reflective layer 12 can also be constructed by coating silver to greatly reduce the material cost.

The main mechanical structure (environmentally friendly foamed plastic structure layer 11) in the lamp housing 10 of the present utility model can be made of recycled foamed plastics, or biodegradable foamed plastics with foaming technology, and after molding During the process, it can be firmly combined with the pre-processed reflective layer 12, so it can be widely used in general lamps as shown in FIG. 5 or backlight modules as shown in FIG. It can also make the overall lamp or backlight module more environmentally friendly.

To sum up, the utility model provides a better and feasible lamp housing structure, so an application for a new patent is submitted according to law; the technical content and technical characteristics of the utility model have been disclosed as above, but those who are familiar with this technology may still The disclosure of the utility model makes various replacements and modifications without departing from the spirit of the utility model.
