2021-08-18

LED chip beads manufactured using FPC circuit boards, LED lights, and high-quality silicone housings. They offer excellent waterproof performance, operate safely on low-voltage DC power, and are available in a wide range of vibrant colors. For outdoor applications, they provide superior resistance to UV-induced aging and yellowing, as well as outstanding high-temperature tolerance, making them ideal for use in architectural contour lighting, decorative lighting in entertainment venues, advertising displays, and other similar applications. The following section outlines the key features of side-view full-color LED chip beads.

1. Can be bent freely and securely fixed to both concave and convex surfaces.

2. Every two LED lights can be configured with a ring circuit.

Small size, rich colors;

4. High brightness, adjustable light-emitting angle, easy installation, and customizable length.

5. Energy Efficiency: Constant-current drive, ultra-low power consumption, and nearly 100% photoelectric efficiency.

6. Environmental Protection: No ultraviolet or infrared radiation, no heat generation, and no risk of mercury leakage.

7. Long lifespan: 50,000 to 80,000 hours—more than ten times longer than traditional fluorescent lamps.

LED stands for “light emitting diode,” and an LED bulb is the common, colloquial term for a light-emitting diode.

1. Voltage: LED chips operate on low-voltage power supplies, with typical operating voltages ranging from 2 to 4 volts, depending on the specific product; they are driven by a high-voltage power supply. This makes for a safer power solution, particularly suitable for public spaces.

2. Current: The operating current ranges from 0 to 15 milliamperes; as the current increases, the brightness also increases.

3. Efficiency: Energy consumption is 80% lower than that of incandescent lamps, with comparable luminous efficiency.

4. Versatility: Very high. Each LED chip in the module is a 3–5 mm square, allowing for the creation of components in a wide variety of shapes, making it ideally suited for dynamic and ever-changing environments.

5. Response Time: Incandescent lamps have a response time on the order of milliseconds, while LED lamps have a response time on the order of nanoseconds.

Environmental pollution: No harmful mercury.

7. Color: Changing the current alters the color. By employing chemical modification techniques, the band structure and bandgap of the material in light-emitting diodes can be easily tuned, enabling multi-color emission in red, yellow, green, and orange. For instance, a red LED at low current will, as the current increases, gradually shift to orange, then yellow, and finally green.

1. LED bulbs have different power ratings.

High-power LED lamps typically use 1 W high-power LED chips, a mix of 1–3 W high-power LED chips, and COB high-power LEDs. The power of a single high-power LED chip can exceed 200 watts.

Low-power LED lights typically use surface-mount beads.

2. Different costs

From the perspective of the cost of side-mounted full-color LED chip products, high-power side-mounted full-color LED chips are more expensive than low-power ones. First, the cost of the high-power LEDs themselves is higher. Second, high-power LEDs require aluminum heat sinks, whereas low-power LEDs can meet thermal requirements by relying on natural heat dissipation through standard PCBs.

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.
