What are the common types of LED outdoor lighting fixtures?

Before understanding LED outdoor lighting, let us first understand the relevant knowledge of lamps. A lamp refers to an appliance that can transmit light, distribute and change the light distribution of a light source. It includes all parts required for fixing and protecting the light source except the light source, and also includes the wiring accessories necessary for connection to the power supply. Lamps are used in all aspects of our lives. Our daily lives are inseparable from them, and human progress and social production are also inseparable from them. The types of lamps have become richer, and various lamps are emerging in endlessly. LED outdoor lighting lamps are a widely used lamp.

Types of LED outdoor lighting fixtures

1. LED street lights

Used for traffic lighting at night.

2. Solar street lights

The sun is the energy source, the battery stores energy, and the LED light is the light source. It can be charged during the day and used at night.

3. Garden lights

Most lamp tubes and light stands are installed on the courtyard floor; they are used in parks, street gardens, hotels, industrial and mining enterprises, courtyards of government schools and other places.

4. Underground lights

Sturdy and durable, anti-water seepage, and excellent heat dissipation performance; widely used in shopping malls, parking lots, green belts, parks, underground lights, tourist attractions, Residential areas, urban sculptures, pedestrian streets, building steps and other places.

5. Wall washers

Architectural decorative lighting or outlining the outline of large buildings.

6. Tunnel lights

In order to solve the "black hole effect" or "white hole effect" caused by sudden changes in vehicle brightness, special lamps are used for tunnel lighting.

7. Landscape lights

High ornamental value, coordinated with the history and culture of the scenic spot and the surrounding environment. It is suitable for landscape places such as squares, residential areas, public green spaces, etc.

8. Lawn lights

Is a lighting facility used around lawns, which adds safety and beauty to urban green spaces. It is simple to install and highly decorative. It can be used around lawns in parks, villas, etc., as well as in pedestrian streets, parking lots, squares and other places.

9. Underwater light

The appearance is similar to some underground lights, and the chassis is fixed with screws.

10. Fountain lights

Widely used in square landscape fountains, garden fountain background lighting and other places.

11. Guardrail pipe

It has physical properties such as waterproof, dustproof, ultraviolet protection, high temperature resistance, cold resistance, environmental protection, energy saving and long service life. Widely used in bridges, roads, building walls, parks, squares, entertainment venues and other places.

12. Stage lighting

Provide a comprehensive vision of the characters and specific scenes required according to the development of the plot.

13. Mobile lights

Commonly used in indoor, mobile workplaces and outdoor TV, movie photography and other places.

14. Traffic lights

There are three types of traffic lights: red, yellow and green. A signal light used to direct traffic.

15. Car lights

Various traffic lights to ensure safe driving. Divided into two categories: lighting lights and signal lights.

16. Light strips/strips

Light strips are another name for light strips and are named after their shape.

Precautions for LED outdoor lighting installation

1. The working environment of outdoor LED lamps that outdoor lighting designers must consider

Due to the complex working environment, the temperature , ultraviolet light, humidity, rain on rainy days, sand and dust, chemical gases and other natural conditions. The impact of environmental factors on LED outdoor lighting fixtures should be considered when designing outdoor lighting.

2. Outdoor LED chip packaging technology

Currently, most domestically produced LED lamps (mainly street lamps) are assembled using multiple 1W LEDs in series and parallel. This method It's called packaging technology. Use 30W, 50W or even larger modules for assembly to achieve the required power. The packaging materials of these LEDs are encapsulated with epoxy resin. The difference between the two is that epoxy resin encapsulation has poor temperature resistance and is prone to aging over time. Silicone packaging has better temperature resistance, so you should choose carefully when using it.

3. Things that should be paid attention to in the selection of heat dissipation materials for outdoor LED lamps

Select aluminum or aluminum alloys, copper or copper alloys, and other alloys with good thermal conductivity.

4. Research on the design of radiator for outdoor LED lamps

1. Clarify the power required for heat dissipation of LED lamps.

2. Use the scattered type. Cost comparison: natural convection cooling has the lowest cost, strong wind cooling has medium cost, heat pipe cooling has a higher cost, and jet cooling has the highest cost.

3. Design radiator parameters: thermal conductivity of metal, thermal resistance of chip, radiator, surrounding air, etc.

4. Calculate the volume, area and shape of the radiator.

5. At room temperature of 39℃--40℃, does the temperature of the lamp meet the heat dissipation requirements? If not, recalculate and adjust.

6. Determine the maximum permitted operating temperature of the LED lamp (ambient temperature plus the permitted temperature rise of the lamp),

7. Ensure that it is waterproof, dustproof, anti-aging, and fastened with stainless steel bolts , and then refer to the latest technical specifications for outdoor lighting fixtures promulgated by our country, as well as urban road lighting design standards.
