What does IP wateproof rating means and what value are recommended IP levels for the bathroom

WHAT DOES IP PROTECTION MEAN?

The IP protection index is an essential feature of most electrical equipments and indicates the degree of protection of the device against external factors such as solid objects or liquids. This protection is expressed by the word "IP", followed by 2 numbers that indicate

The first digit describes the degree of protection against solid objects, dust, solid particles and bodies
The second digit describes the degree of protection against liquids

The IP rating is relevant when the environmental conditions are normal. For hazardous environments, special protection is required.

Although there are numerous combinations of IP ratings for LED strips, the most common are IP67, IP65, IP44, IP20.

In general, all LED strips have IP20 protection, IP44 can be found for LED strips within an aluminum profile with closed end caps and IP65 or more is normally used for waterproof LED strips.

How to build environmental friendly Linear LED fixtures

Linear lamps are the most popular light source in the office and commercial sectors, with billions of linear lamps installed across the world, operating 11 hours on average each day of the year. Added up, the office and commercial sectors account for near half of the lighting electricity consumed on the planet.

LED linear fixtures must be environmental friendly with focus on energy efficiency, durability, and exclusion of dangerous substances. Those they replace, the linear lamps consisting of fluorescent lamps, are not environmental friendly, with short lifespan, high mercury content and UV light emissions.

What defines an environmental friendly LED linear lamp?

The Nichia E17A and E21A CSP LED series

Nichia CSP LEDs

A micro-sized, high brightness powerful LED package is referred to as CSP (Chip Scale Package) LED. CSP makes the LED smaller while having the same power.

A CSP LED is equal to an LED chip or can be a maximum of 20% larger and thus has a high light intensity. It also does not contain a wire connection like conventional SMD LEDs, a factor that makes it a more stable product, with better thermal performance than conventional LEDs.

As a result, the Direct Mountable Chip technology slashes at one major element of system cost: heat management. With thermal resistance of only 0.3 (℃/W junction to Ts measuring point), heat sinks can be smaller or higher performance can be obtained without increasing the heat sink.

Featuring the Direct Mountable Chip technology the new E17A and E21A CPS LED series from Nichia are direct mountable, packageless, chip scale LEDs which reduce total system cost and increase performance at the same time.

Flip-Chip LED Test: Nichia is the performance leader

p>As a manufacturer, we aim to use the newest LEDs technology in our LED strips and modules. One particularly interesting new technology is the Chip Scale Packaged LEDs, known as CSP or Flip-Chip LEDs.

Before choosing the best performing CSP LED for our products we have compared more than a dozen models from the top LED manufacturers: Nichia, Samsung, Philips Lumileds and Seoul Semiconductor.

For a meaningful comparison we selected LEDs that function at 350 and 700 mA with a voltage between 2.75 and 3.2 V.

For each category we compared the luminous flux and luminous efficacy at the usual junction "lab temperature" of 25ºC and at a more realistic 100ºC. The comparison data is that from the manufacturers datasheet.

CSP at 700mA, maximum 2.5 Watt, for street or outdoor lighting, 5000K, CRI 70.

At 25ºC The Nichia CSP LED has 20% higher flux (304 lm) and 27% better efficacy (145 lm/W) than the second performer, Seoul WICOP (247lm and 114 lm/w). Luxeon Flip Chip White 10 has similar performance (242 lm/w 115lmw) to Seoul while Samsung lags somewhat behind (210 lm and 95 lm/w).

Chip Scale Packaged (Flip Chip) LED technology: Explained

With the development of LED lighting and the high demands of consumers, LED chip manufacturers are continuously improving and innovating. The development of Chip Scale Packaged (Flip Chip or CSP) LEDs is such an inovation, with several advantages: no substrate, solderless cabling, small size and high optical density.

CSP, or Chip Scale Package, is defined as an LED package with a size equivalent to an LED chip, or no larger than 20%. The CSP product has integrated component features that do not require soldered wire connections, reducing thermal resistance, reducing the heat transfer path, and reducing potential sources of error.

Usually, a light emitting diode (LED) has two key components, the LED chip that emits the light and the LED package which focuses it, enables assembly into lighting products and transfers the heat away to the heat sink.
