Description

A hanging LED street light

technical field

The utility model belongs to the technical field of semiconductor lighting, in particular to a hanging LED street lamp.

Background technique

LED lights are lights that use light-emitting diodes as light sources. As a solid-state cold light source, LED lights have the advantages of high luminous efficiency, long life, low energy consumption, and environmental protection. At present, LED has been widely used in public places and indoor lighting, and also plays a good role in road and tunnel lighting.

In road lighting, a traditional street lamp is generally composed of a lamp post, a lamp arm and a lamp. The light-emitting lamp is installed on the lamp arm, and the lamp arm is installed on the top of the lamp post, and then the lamp post is fixed on the ground. However, in the narrow alleys of the living area or in areas with lush greenery, there are relatively large limitations in arranging such street lights installed on light poles. First of all, the shading of trees and buildings will affect the lighting effect of street lights. At the same time, light poles occupy the limited space on the ground, which affects the overall layout; secondly, the laying of light poles also increases the cost of street lights. In addition, in ordinary road lighting, although traditional street lamps can roughly meet the requirements of use, there are still some problems. For example, there are certain limitations in the structural design of lamps, the uniformity of illumination provided in the vertical direction of traffic is not high enough, and the glare problem caused by uneven illumination; at the same time, street lamps with traditional structures require that the installation angle of lamps be strictly in accordance with the design. However, it is difficult to ensure this in actual operation, and the assembly efficiency is low, which will cause the street lamps to fail to provide the uniform brightness required by the design.

Contents of the invention

The utility model aims to provide a suspended LED street lamp with low energy consumption and high light efficiency, which avoids tree shading, improves the appearance of the overall layout, reduces costs, avoids occupying limited space on the ground, is easy to install, and can evenly illuminate.

The suspended LED street lamp provided by the utility model includes n (n≥2, usually 10≥n≥2) metal base plates, hinges and steel cables, and the metal base plates are connected in pairs by hinges arranged on the edges, so that n pieces of metal bottom plates are combined to form a closed LED lamp, and the closed LED lamp is fixed on the steel cable through a U-shaped screw, a fastener or a self-closing structure.

The metal bottom plate is a flat plate or an arc-shaped plate with a certain curvature.

An LED light source module, an optical device and a driver are installed on the metal bottom plate facing the ground in the closed LED lamp.

The cross-sectional shape of the closed LED lamp can be a circle, an ellipse or a polygon, a combination of circular arcs, elliptical arcs, parabolic arcs, and straight lines, or other regular or irregular closed shapes.

The metal bottom plate is assembled into a closed lamp during installation, and is fixed on the steel cable through a U-shaped screw, a fastener or a self-closing structure. When installed, it is suspended directly above the road by steel cables.

Compared with the prior art, the utility model has the following advantages:

The lamps are flexible and convenient to install, and can be hung between the roadway and trees, which can effectively avoid trees and buildings from blocking the lights. At the same time, the structure can reduce the occupation of ground space and avoid the impact on the overall appearance of the ground. In addition, the steel cable suspension structure It can also reduce the cost of installing light poles.

The LED lamp of the utility model is composed of flat or arc-shaped metal bottom plates with a certain curvature connected by hinges, has a stable structure, and is convenient for installation and disassembly. The LED light source module, driver, and optical devices are all installed on the metal base plate, which has good heat dissipation effect, easy processing, and good connection strength.

The lamp of the utility model can realize completely symmetrical light distribution, and can also design asymmetric LED arrangement on both sides according to lighting requirements, so that the lamp can be suspended above the road surface to provide uniform illumination and ensure uniform brightness in the longitudinal direction of the road surface. The degree is above 0.7, and the problem of glare is avoided.

Detailed ways

The embodiments described below are only some embodiments of the present invention. All other embodiments without creative achievements based on the embodiments of the present utility model belong to the protection scope of the present utility model.

Referring to Fig. 1, a suspended LED street lamp is composed of six flat metal base plates 1-6, and the metal base plates 1-6 are connected by hinges 7 to form a closed hexagonal LED lamp. The metal bottom plate is made of stainless steel, which makes the lamp have good strength and thermal conductivity. The shape of the lamp can be personalized according to different needs. The light distribution of the LED light-emitting module should be combined with the shape of the lamp so that the lamp can provide uniform illumination for the ground.

As shown in Figure 3, white LED light source modules 12 with a color temperature of 4500 K are installed on the metal base plate 3~5, and the LED modules are arranged in an array, and the light distribution is performed through a microstructured diffusion plate. At the same time, two ends of the metal base plate 1 are provided with screw holes 8, so that the lamp can be fixed on the steel cable 10 through the fixing piece 11.

Referring to Figures 2 and 3, when the utility model is installed, 6 pieces of metal bottom plates are assembled into closed lamps through hinges. Screw holes 8 are opened at both ends of the metal bottom plate 1 on the top surface of the lamp, and the fixing parts 11 and steel cables are connected to each other. 10, and fixed and tightened with screws 13 to prevent displacement or collision between the lamp and the steel cable after installation. Steel cable 10 can be fixed on the suspension bar 9 of road both sides or wall.

The suspended LED street lamp of the utility model has the advantages of small size and flexible installation, can be applied in parks or forests, and can effectively solve the problem of trees and buildings blocking lamps.
