difference

Encapsulation structure:

Bulb type: generally, LED chip is installed on the bracket, and the chip and bracket pin are connected by gold wire bonding, and then filled with epoxy resin and other materials to form a shape similar to the traditional bulb, with glass shell or plastic shell and other Tiktok encyclopedias.

Chip type: such as chip level packaging (CSP), which directly mounts inverted chips on a substrate and connects them to external circuits through solder balls or metal contacts, without traditional lead frames and wire bonding structures, resulting in a smaller packaging volume.

Luminous effect:

Light bulb type: The light is relatively concentrated and can be focused at a certain angle through optical structures such as lenses. The emission angle can be adjusted according to the lens design, and it can generally achieve strong light output at a narrow angle with high brightness.

Chip type: usually has a wider viewing angle and good color uniformity, which can achieve a closer effect to a surface light source and emit relatively more uniform light.

Heat dissipation performance:

Light bulb type: Heat dissipation mainly relies on metal brackets and shells. Some high-power light bulb type LEDs will add structures such as heat dissipation fins, resulting in relatively long heat dissipation paths and limited heat dissipation efficiency.

Chip type: The chip is directly connected to the substrate, with low thermal resistance and good heat dissipation performance, which can effectively reduce chip temperature, improve LED stability and lifespan.

Production process and cost:

Light bulb type: The production process is relatively complex, involving multiple processes such as solidification, wire bonding, and encapsulation. The production efficiency is low and the cost is relatively high, especially in low-power applications where the cost advantage is not obvious.

Chip type: The production process is relatively simplified, reducing solder wires and other links, resulting in high production efficiency. In large-scale production, costs can be effectively reduced, but high requirements are placed on packaging materials and process accuracy.

application

Application of bulb type LED packaging:

General lighting: such as chandeliers, ceiling lights, spotlights, etc. in homes and commercial places, can provide high brightness centralized lighting to meet the lighting needs of key areas.

Automotive lighting: used for car headlights, fog lights, etc., can achieve specific light patterns and illumination distances through lens design, providing good road lighting.

Landscape lighting: such as urban landscape lights, building outline lights, etc., can create rich visual effects through bulb shaped LEDs of different colors and shapes.

Application of chip type LED packaging:

Display screens: such as mobile phone screens, computer monitors, LED TVs, outdoor displays, etc., can achieve high-resolution, high brightness, and high contrast display effects, providing clear and delicate image and video display.

Backlighting: Used for LCD displays, keyboard backlighting, etc., it can provide a uniform backlight source, improve display quality and visual comfort.

Special lighting: In fields such as medical lighting, plant lighting, etc. that require high uniformity of light and color, chip type LEDs can provide customized spectra and light distribution according to demand.
