Abstract:
Nowadays, led light comes into our life in everywhere, regardless of LED light bulbs, LED displays, and LED instrument panels. Most production are lights, but do you actually know the differences in those?
Different led light fixture uses different LED tech, such as led tubes, bulbs and chips. This article will then introduce them and compare their diversities in actual adoption.
Led chip
The LED chips are the core component of a light-emitting diode (LED). It is a small semiconductor device made of materials such as gallium, indium and nitrogen compounds. And its chip LED is made of semiconductor material that emits light when electricity passes through it (electroluminescence). And the LED chip can emit different colors of light, which is determined by its type.
There are two main types of LED chip light: SMD LED(Surface Mount Device) and COB (Chip on Board). The former is commonly used for compact and versatile LED chips for strip lights and displays. The latter, on the other hand, integrates multiple LED chips onto a single substrate for more intense and even illumination.
Take SMD LED as an example: what is an SMD led?
SMD-- surface mount led chips are compact, rectangular or square in shape and can be mounted directly onto a printed circuit board. They are usually rectangular or square, very small in size, usually white or yellow, ranging from 1 mm to 5 mm, with the top of the chip led and the light emitting area usually covered by a clear or PC lens.
The top of the chip is flat and the SMD LED led light emitting area usually covered by a transparent or PC lens, while the side or bottom of the chip has metal contacts or pads instead of the traditional leads, which can be connected directly to the printed circuit board.
LED Tube Lights
The tube light is a cylindrical lighting fixture designed to replace traditional fluorescent tube light fixture. Tube lights use LED (Light Emitting Diode) technology for greater energy efficiency, longer life and a more stable light source.
LED tube light is often designed in cylindrical and elongated shapes, similar to traditional fluorescent tubes. Common lengths include 2ft, 4 foot led shop lights and 8ft led shop lights. The housing is made of clear or frosted plastic or glass, which diffuses the light while protecting the internal components.
Inside the tube lighting, there may be visible strips or chips of LEDs that emit a light that is usually uniform and can appear to be bright white, warm white or daylight, depending on the colour temperature selected.
LED Light Bulbs
An LED headlight bulbs are a light bulb that uses Light Emitting Diodes (LEDs) to emit light. They are able to provide full brightness immediately after being switched on, unlike some fluorescent bulbs which need time to warm up.
LED lights vs incandescent light bulbs come in a variety of shapes, sizes and colour temperatures (warm white, cool white, daylight) for use in different environments. They do not contain toxic substances such as mercury and are fully recyclable. Typically, LED bulbs are similar in shape to traditional incandescent bulbs, such as the Edison base bulb.

The different types of LED techs :
LED chips are individual semiconductor devices that emit light when current is passed through them. They are usually small and compact, often mounted on circuit boards or heat sinks, and do not have a specific shape like a light bulb or LED street lamp.LED chips are used in a wide range of applications, including screen, automotive lighting, and decorative lighting. Depending on the semiconductor material used, they can emit different colors and brightness however, they require additional components and design to be integrated into lighting fixtures.
LED bulbs are complete lighting fixtures consisting of multiple LED chips packaged together and are designed to replace traditional incandescent or fluorescent bulbs. Designed to replace traditional incandescent or fluorescent bulbs, LED bulbs are available in standard shapes (e.g. e12 led bulb) and bases to fit existing fixtures. They are primarily used for general lighting applications in residential and commercial environments. These bulbs are also available in a variety of colour temperatures, such as warm white and cool white, and typically provide a wide beam of light.
In contrast, LED light tube light is lengthened luminaires designed to replace fluorescent tube light, making them ideal for commercial and industrial environments. They are typically long and cylindrical and come in standard lengths (such as 2ft and 4 foot led shop lights) to fit specific fixtures.LED light tube is commonly used for overhead lighting in offices, schools, warehouses and retail spaces. They offer high lumen output and uniform light distribution and can be a commercial led lighting solution and industrial led lights solution.
Summary of above led light chart:
| Feature | LED Chips | LED Bulbs | LED Tubes |
| Definition | Individual light-emitting components | Complete lighting units | Elongated lighting fixtures |
| Physical Form | Small and compact | Standard bulb shapes | Long and cylindrical |
| Usage | Versatile (decorative, backlighting) | General lighting in homes/commercial | Overhead lighting in commercial/industrial |
| Light Emission | Varies by design | Various color temperatures | High lumen output, even distribution |
| Installation | Requires additional design | Easy, direct replacement | May need specific fixtures |
Common features of LEDs:
LED chips, bulbs and tubes share common characteristics such as high energy efficiency, long life and low heat generation. They are environmentally friendly, contain no hazardous substances such as mercury and require no warm-up time to provide instant lighting. This helps to reduce power consumption, maintenance costs and environmental impact, while providing consistent and reliable lighting.
Conclusion:
In short, although LED chips, bulbs and tubes are all led lighting technology, they are used in different functions and applications in the lighting industry. LED chips are the basic components used in a variety of led devices, while tube LED lights are replacements for traditional light bulbs, and tube lights LED are designed for high efficiency overhead lighting in larger spaces, and there are even some that can be freely combined.
