2021-11-04

　　 Side full-color LED chip Also known as a chip-type light-emitting diode, it is a simple type of lamp. Its principle of light emission is based on passing an electric current through a compound semiconductor; as electrons and holes recombine, the excess energy is released in the form of light, thereby producing illumination.

　　So, what issues should we pay attention to when using full-color side-mounted LED chips?

　　1. When cleaning, do not use unknown chemical solutions to clean LEDs: such solutions may damage the LEDs. If cleaning is necessary, soak the SMD LED in alcohol at room temperature for no more than 1 minute, then allow it to air dry naturally for 15 minutes before resuming use.

　　2. Moisture protection: To prevent moisture absorption during transportation and storage, SMD LEDs are packaged in moisture-barrier aluminum bags that contain desiccant and a humidity indicator card. The desiccant primarily controls the humidity inside the bag, while the humidity indicator card continuously monitors it.

　　3. Seal the storage bag and store it at a specified temperature.

　　 Side full-color LED chip It is now possible to package more LED chips within a smaller footprint, while using lighter PCBs and reflective-layer materials—indicating that the reflective layer requires less epoxy resin. By eliminating the heavy carbon-steel pins and reducing the overall dimensions, the product weight can be easily cut in half, with its volume and weight reduced to about one-tenth of those of conventional through-hole components. With chip-on-board packaging, electronic products can achieve a 40%–60% reduction in volume and a 60%–80% reduction in weight.

　　In-line LEDs are encapsulated using a potting process. The encapsulation procedure involves first injecting liquid epoxy resin into the LED mold cavity, then inserting the wire-bonded LED leadframe, curing the epoxy in an oven, and finally separating the LED from the mold cavity to complete the molding. Due to its relatively simple manufacturing process and low cost, this type of LED enjoys a high market share.

　　The advantages of full-color LED chip-on-board on the side are as follows:

　　1. The side-view full-color LED chip is extremely small—essentially a tiny die encapsulated in epoxy resin. Its minuscule size makes it highly versatile for designing various light sources and fully meets the requirements of LED flexible light strips.

　　2. Solid color: Side full-color LED chip Its pearlescent hue is pure, soft, and glare-free, making it suitable for primary decorative applications as well as lighting products.

　　3. Low Heat Generation: The LED power of the microcontroller is low, typically ranging from 0.04 to 0.08 W, and it boasts high luminous efficacy, resulting in minimal heat generation.

　　4. Energy Efficiency: High luminous efficacy and low heat generation make LED components energy-efficient. Compared with traditional lighting and decorative lamps, LED lights consume several times less power while delivering significantly superior performance.

　　5. Low radiation: The light spectrum contains no ultraviolet or infrared rays, meaning there is neither heat nor radiation; glare is minimal, the light source remains cool, and it can be safely touched. It is a typical light source for green building lighting systems.

　　6. Environmental Protection: The materials used for the full-color LED chip on the side are environmentally friendly, recyclable, and will not pollute or damage the environment even with extensive use.

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.
