Abstract

The utility model relates to the technical field of lamp products, particularly a lamp for outdoor use. The utility model comprises a lamp holder that is provided with a luminous device and a lamp shade that is covered on the luminous device, wherein, the lamp shade comprises an upper lamp shade that is made of water impermeable materials and a lower lamp shade that is positioned below the upper lamp shade. The upper lamp shade and the lower lamp shade are fixedly connected by a connecting rod, wherein, the top part of the upper lamp shade is provided with an end surface, the lower part of the upper lamp shade forms a lower port that is covered at the upper port of the lower lamp shade, that is the upper port of the lower lamp shade is shielded by the upper lamp shade, and a certain gap is arranged between the side walls of the upper lamp shade and the lower lamp shade. After the utility model adopts the structure, the utility model adopts the structure mode that the upper lamp shade and the lower lamp shade are overlapped, wherein, the upper lamp shade adopts the water impermeable materials that can prevent rain dropping. Meanwhile, the utility model adopts the open type structure, which is convenient for heat dissipation and the luminous device. Additionally, the certain gap is arranged between the upper lamp shade and the lower lamp shade for air convection, and the utility model further reduces the heat reserved in the lamp shade.

Description

A kind of light fixture of outdoor use

Technical field:

The utility model relates to the light fixture product technical field, refers in particular to a kind of light fixture of outdoor use.

Background technology:

The light fixture of present outdoor use is in order to guarantee security of products, make its internal circuit can not be subjected to the influence of external environment (mainly being natural phenomenas such as rain, snow), lighting all must be provided with a lampshade, and the lampshade that this type of light fixture adopted mostly is full shielded type, and promptly lampshade wraps up whole illuminator.Though can play protective effect like this to light fixture; but it also has certain weak point: at first; because what illuminator was adopted at present is still based on the electric heating light source; be that illuminator will produce a large amount of heats in luminous; because lampshade is full shielded type, its inner heat can't in time exhale, and causes product to be in the higher working environment of temperature for a long time; make it be prone to job insecurity, undesirable condition such as reduce the service life of working part greatly.Secondly, lampshade adopts full shielded type, makes also relative complex of installation process, and replacing illuminator (being bulb) also comparatively bothers.

Summary of the invention:

The purpose of this utility model is intended to overcome the deficiency of the said goods, provide a kind of simple in structure, heat dispersion is good, easy for installation, be easy to change the light fixture of the open air use of illuminator.

The utility model is achieved by the following technical solution: this product comprises the lamp socket that light-emitting device is installed and covers at lampshade on the light-emitting device, described lampshade comprises upper lamp shade that adopts the impermeable material making and the lower lamp shade that is positioned at the upper lamp shade below, and upper and lower lampshade is fixedly connected by connecting rod; Wherein the upper lamp shade top is provided with an end face, and the lower port that its underpart forms is placed on the upper port of lower lamp shade, and promptly the upper port of lower lamp shade is covered by upper lamp shade, and has certain interval between upper and lower lampshade sidewall.

After the utility model adopts this structure, it adopts the frame mode of lower lamp shade stack, and wherein upper lamp shade adopts impermeable material, can prevent splashing into of rainwater, and adopt this open structure simultaneously, be convenient to scattering and disappearing and light-emitting device being changed of heat.Between last lower lamp shade, also leave certain clearance in addition,, further reduce the heat that stays in lampshade so that cross-ventilation to be provided.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the stereogram of the utility model lampshade part;

Fig. 3 is a stereogram of the present utility model.

The specific embodiment:

The following stated only is a specific embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See accompanying

drawing

1,2,3, the utility model comprises: the lamp socket 1 of light-emitting device 11 is installed and covers at lampshade 2 on the light-emitting device 11, described lampshade 2 comprises upper lamp shade 21 that adopts the impermeable material making and the lower lamp shade 22 that is positioned at upper lamp shade 22 belows, and upper and

lower lampshade

21,22 is fixedly connected by connecting rod 3; Upper lamp shade 21 all is frustum of a cone moulding with lower lamp shade 22, wherein upper lamp shade 21 tops are provided with an end face 211, the lower port 212 that its underpart forms is placed on the upper port 221 of lower lamp shade 22, the upper port 221 that is lower lamp shade 22 is covered by upper lamp shade 21, and has certain interval between upper and

lower lampshade

21,22 sidewalls.

Above-mentioned upper lamp shade 21 upper surfaces 211 offer a through hole 213, and lower lamp shade 22 upper port 221 places are provided with a junction 222, and connecting rod 3 lower ends are threaded with the connecting portion 222 of lower lamp shade 22; The through hole 213 that its upper end is passed on the upper lamp shade 21 is threaded with a contiguous block 4, so not only plays the effect that

lower lamp shade

21,22 connects, and also with 213 sealings of the through hole on 21 sections end faces 211 of upper lamp shade, guarantees that rainwater can not flow into along through hole 213.In addition, lower lamp shade 22 is connected with light-emitting device 11 on the lamp socket 1 by connecting portion 222, keeps relative stability.

After the utility model adopts this structure, it adopts the frame mode of

lower lamp shade

21,22 stacks, wherein upper lamp shade 21 adopts waterproof material (as alloy, plastic material or the like), can prevent splashing into of rainwater, and adopt this open structure simultaneously, be convenient to scattering and disappearing and light-emitting device 11 being changed of heat.Between last

lower lamp shade

21,22, also leave certain clearance in addition, cross-ventilation can be provided, further reduce the heat that stays in lampshade 2.
