Cree has announced the XHP35 family of packaged LEDs that will include products in both High Density (HD) versions with a domed primary optic and High Intensity (HI) versions with a flat primary optic. The new products mark the introduction of what Cree calls the SC5 (silicon carbide 5) technology platform being fully utilized in an LED in the 3.45×3.45-mm form factor, or what Cree calls the XP footprint based on prior packaged LEDs such as the XP-G/G2, XP-L and XP-E/E2.
The new packaged LEDs output a maximum 1833 lm from a single emitting surface, putting the LEDs in a class with multi-die LEDs in discrete packages but without the optical inefficiency of multi-die LEDs. Cree will supply the LEDs across the range of 2700K to 8300K in CCT; in 70-, 80-, and 90-CRI flavors; and in 2- or 3-step MacAdam ellipse bins.
Cree announced the SC5 platform back in late 2014 and began shipping the first XHP50 and XHP70 packaged LEDs at the beginning of 2015. The XHP prefix stands for extreme high power, and at the SC5 introduction Cree said the new platform delivered double the performance of prior LEDs relative to the same package sizes. Now that performance comes to what has been traditionally the most popular footprint for high-power LEDs.
As has been its custom, Cree will use the new LEDs and footprint legacy to allow customers to upgrade existing solid-state lighting (SSL) products with the simple change of an LED. "We’re excited that the XHP35 LED brings the performance of Cree’s Extreme High Power LEDs to the XP footprint," said Jorge Fraile, CEO of Hispaled. "In addition to delivering an impressive amount of light, the XHP35 LED allows us to leverage existing drivers to achieve the full performance of Cree’s high-power LEDs at lower drive currents."
Cree also has launched the new family in both of the aforementioned HI and HD flavors. Cree first began using the term HD to describe new discretely-packaged and chip-on-board (COB) LEDs with SC5 performance and what the company noted as better optical control factor (OCF), essentially touting the better beam control achievable with more flux from a smaller source. More recently, Cree launched the HI LEDs in the XP-L family, saying the flat optic makes the source appear smaller through a secondary optic and enabling higher center-beam candle power (CBCP).
The XHP35 packaged LEDs are immediately available in both flavors. The XHP35 HD LEDs target applications such as outdoor and high-bay lighting that requires maximum total flux. The XHP35 HI LEDs target applications such as stadium and indoor directional lighting with maximum cd on target.
"Cree continues to redefine the performance of high-power LEDs," said Dave Emerson, vice president and general manager for Cree LEDs. "The XHP35 LED represents a breakthrough that goes well beyond the incremental advances of other LED suppliers. Now, more than ever, manufacturers will be able to tap the full power of extreme high-power LEDs to forge lighting designs that were previously thought to be impossible."
Over the last five years, there has been a push to introduce smart technology into the home. Refrigerators are smart, T.Vs are smart, and now, so is lighting. While the push towards smart lighting has been slow, the possibilities now seem endless for this new lighting fad. But could the push for smart technology in the home end up costing you more money and stress? Some see it as the wave of the future, while others just want a light that turns on and off.
Your Lighting Just Got Smarter It’s amazing what you can do with a smartphone and Wi-Fi these days. Some refrigerator models can tell you when you’re running low on milk, for example, and you can make sure you locked your doors at home from your office. But really, one of the most impressive of the new ‘smart’ technologies is the smart light. Products like Philips’s new Hue are paving the way towards a brighter, and more colorful future.
If you are away from home on vacation, you can set certain lights to turn onto a certain brightness to give the illusion that the space is occupied. Also, when you’re walking home from a day at work, your phone can send signals to your lights that you are approaching your home. With certain settings on the app, you can make it to where, as you approach your door, the porch light comes on. Once you get to the door, your kitchen and living room light will come on. Also, these lights change color, so depending on the time of the day or on the lighting that you’d like to have for a party, you can pick up your phone and change from red to blue or pink to purple. These new technologies will prove to be the future of lighting, but there are still quite a few kinks to be worked out.
The Problems with Smart Lighting As with most new ‘smart’ technologies, the makers of the products are still working out the kinks. First of all, these new lights are LED. LED technology has advanced greatly since it was invented, but there are still some problems. LED lights are extremely sensitive to humidity and heat, for example, so these lights cannot be placed outdoors. Although Philips states that the electricity usage of these lights is 80% less than other lights, you will end up charging your phone and using a bit more Wi-Fi than you normally would since these lights are dependent on Internet technologies. Also, these lights take a tremendous amount of time to set up. To install, program, and use these lights takes around 3 hours, as opposed to the old school ‘twist-and-go’ light bulbs of days past.
It’s not doubt that these lights are the wave of the future, but, as with all new technologies, there will be a grace period where these lights aren’t living up to their potential. There may be a few problems, but time will surely fix them, and your home lighting is about to get a lot more intelligent.
It doesn’t really matter where the future of lighting is going, because chances are you’ll still need a light cover.
