　　This utility model relates to the field of transportation, particularly to a long-life transportation… High-power LED indicator The rapid increase in energy-transfer vehicles has posed a threat to pedestrian safety when crossing streets. Currently, incandescent lamps used in urban traffic signal systems are characterized by complex structures, heavy weight, large dimensions, high wattage, and a tendency to burn out easily, resulting in short lamp life, inconvenient routine maintenance, and high power consumption—far from meeting today’s demands for such products.

　　

High-Power LED Indicator Lights – High-Power LED Indicator Light Manufacturer

 

　　The objective of the technical personnel is to provide a long-life, high-power LED traffic indicator light that features a simple structure, long service life, high brightness, energy efficiency, and easy maintenance, thereby addressing the issues raised in the aforementioned background art. To achieve this objective, the present utility model provides the following technical solution: a long-life traffic High-power LED indicator , including a support base; the top of the support base is fixedly connected to a support column; the top of the support column is fixedly connected to a lamp box; the top of the lamp box is fixedly connected via a bracket to a solar panel; the front side of the lamp box is provided with multiple mounting slots, within which lamp holders are fixedly installed; and lamps are installed inside the lamp holders. The high-power LED indicator lamp comprises a lamp head and a lampshade, with the lamp head fixedly mounted inside the lampshade. The lamp head includes a base plate; the top of the base plate is fixedly connected to a connection circuit board; the bottom of the connection circuit board is fixedly connected to an LED light-emitting chip; a heat sink is fixedly connected to the bottom of the base plate; one side of the lampshade is fixedly connected to a protective cover. This long-life, high-power LED traffic indicator lamp features a reflector housed within the protective cover; the periphery of the reflector is fixedly connected to the inner wall of the protective cover. One side of the connection chamber is provided with an opening structure, and the connection chamber contains a waterproof plate; one side of the waterproof plate is equipped with a maintenance panel, and both the waterproof plate and the maintenance panel are fixedly connected to the lamp box via fixing bolts. A rain shield is fixedly attached to the outer side of the lampshade, and all rain shields have an arc-shaped structure. The protective cover is made of a transparent material. Inside the lampshade of this long-life, high-power LED traffic indicator lamp, a reflective panel is fixedly attached to the inner wall, and the lampshade is flared in shape. At both ends of the base plate of the high-power LED indicator lamp, supporting portions extend in a curved manner; one end of each supporting portion is fixedly connected to the inner wall of the lampshade, while the heat-dissipating portion is set at a certain distance from the lampshade.

　　Compared with the prior art, the aforementioned utility model features long service life in traffic applications. High-power LED indicator Its advantages are as follows: by installing solar panels and storage batteries, light energy can be converted into electrical energy, achieving energy conservation and environmental protection; by incorporating LED chips, the luminance is high, the power output is substantial, the LEDs are resistant to overheating and burning, and their service life is long; the addition of reflectors further enhances brightness; the inclusion of heat-dissipation components cools the lamp base, preventing it from overheating and burning, thereby extending its service life even further; and the installation of a rain shield protects the luminaire, preventing water from entering.

 

More information

What is a light-emitting diode?

Light-emitting diodes are commonly referred to as LED beads. They are used in a wide range of applications and can be seen on streets and in alleys everywhere. For example, traffic lights at intersections remind people to obey traffic rules; remote controls transmit or receive signals; they can be used to display images on ultra-large screens; and various streetlights provide warm illumination at night. Even everyday household appliances rely on their contributions.

What are the tips for selecting LED chips?

1. Brightness: LED brightness varies, and so does the price. LEDs used in LED lighting must comply with laser safety classification standards.

What factors influence the price differences of LED light beads?

LED chips are a well-known product in the LED industry; however, many people are less familiar with their pricing. What causes such wide variations in LED chip prices? Below, we will outline the factors that influence LED chip prices.

What is the light-emitting principle of LED chips?

An LED chip is a light-emitting diode, and an LED bulb is simply the common, colloquial term for an LED.

Are you familiar with full-color LED chip-on-board modules for side mounting?

The brightness of full-color LED surface-mount devices is closely related to the LED’s viewing angle. The narrower the viewing angle, the higher the brightness; moreover, differences in manufacturing processes can lead to significant variations in service life. For a 5-mm LED with a 180-degree viewing angle, the white-light luminous intensity is only a few hundred mcd, whereas for a 15-degree viewing-angle LED, the luminous intensity exceeds 10,000 mcd. When high-power LEDs are used outdoors, the brightness is even greater. Single-power LEDs include 1 W, 3 W, and 5 W models; some high-power LEDs can be combined to form a single high-power LED with output up to several hundred watts. Color temperature is independent of brightness, but brightness is directly related to the lumen value.

Key Considerations for Full-Color SMD LEDs on the Side

Side-view full-color LED chips, also known as surface-mount LEDs, are a type of simple lighting device. Their light-emitting principle is based on passing an electric current through a compound semiconductor; when electrons and holes recombine, the excess energy is released in the form of light, thereby producing illumination.
