LIGHT UP YOUR INDUSTRIAL IoT DESIGN 24 REPLACEABLE BULB VS. INTEGRATED LED – DESIGN CONSIDERATIONS LEDs have gained increased favor due to their many advantages over incandescent bulbs. These include: • Reduced energy consumption • Small size • Long life span • High luminosity The radiance combined with the long life of LEDs creates the unique opportunity to integrate the light source directly into a fixture. However, while the apparent benefits include improved aesthetics and reduced user complexity, design engineers must overcome challenges like increasing a more complex design when integrating the LED. Therefore, it is helpful to review each scenario's requirements to answer whether integrated LEDs are worth the development cost and complexity. The ROHM Semiconductor CSL1104WBx White LED delivers efficient high-density mounting with a compact packaging footprint. Its high luminous intensity of 2.0cd and 0603 size emanate more light in less space. It also offers a high-intensity reflector type and improved color variation, with the latter delivered by subdividing the chromaticity rank system. This benefit simplifies color adjustment and reduces the application development time.

First, the up-front cost of the fixture may be higher than a traditional one, due to the complexity of integration. The added circuitry and internal switches include completing and breaking the circuits when needed. Another requirement is a more complicated installation. A traditional fixture employs a threaded joint to install the The incandescent bulb was popular for a long time due to the simplicity of its replacement. The bulb screws in through a threaded joint, making it out fast and straightforward to replace. The challenge with traditional replaceable bulbs, though, is their lifespan. In addition, the bulbs themselves contained a failure, making the need for replacement clear and simple. Engineers often design a replaceable LED bulb to fit into an incandescent fixture, so lighting is different when someone installs an LED bulb into that circuit. Dimming is an example of common performance degradation that results from swapping an incandescent bulb for an LED one in the same fixture. Furthermore, the maximum output wattage of the fixture remains constant when installing an LED, so the consumer may not get the full benefit of the LED's improved brightness with that constraint.
