At the in-house exhibition, Philips Electronics Japan disclosed the latest products including the power module for LED lighting fixtures that can control the brightness with a wireless switch that does not require a battery, the built-in power supply circuit, and the LED lighting module that can replace the light source.
The power module uses a wireless switch that does not require a battery and supports the IEEE 8000. The module is equipped with an element that generates power by vibration caused by a switch pressing action, and the wireless chip can be activated using the power provided by the element, and the switching action is transmitted to the power module. The company demonstrated the lighting and extinguishing of LED lighting fixtures, as well as the dimming of LED lighting fixtures (slow adjustment of brightness). The company envisions using it for Downlight and Spotlight. Each switch corresponds to a power module that is connected to a particular LED lighting fixture, so the lighting fixture can be controlled as needed. According to reports, although wireless transmission using infrared rays has appeared before, the use of wireless communication technology like this time has a higher degree of freedom in the design of lighting fixtures. The switch end does not need to provide a portion that emits infrared rays on the surface of the casing, and the LED lighting fixture end does not need to provide a light receiving portion on the surface of the casing.
Philips Electronics has partnered with Sanmei Electric to increase its wireless communication capabilities. The life of the wireless switch is 60,000 times and the external dimensions are 40mm × 40mm × 15mm. There are two types of switch vertical and horizontal press. The communication protocol is said to be compliant with the ZigBee Green Power standard.
Increase the freedom of setting LED lighting with built-in power
The LED lighting module has an AC-DC conversion power supply circuit, which is suitable for downlights and the like. The beam is 1100lm and is available in products with color temperatures of 3000K, 3500K and 4000K. The power consumption is 22W, 20W and 19W respectively. The average color rendering index (Ra) is 80. It is scheduled to be launched around the summer of 2010. There is no need to set up a power module. The housing dimensions are 69.7 mm in diameter and 40.25 mm in height. The LED lighting module can be mounted on a pedestal that is placed on a ceiling or the like. When the module is aging, it can be removed from the pedestal and replaced with a new module.
When the power circuit is large in size, it cannot be accommodated in the module, so the initial beam can only reach 1100 lm. In the future, Philips plans to introduce a power supply circuit that supports more power without changing the size of the case, and a product with a beam exceeding 1100 lm. In addition, the LED lighting module has a lifetime of 25,000 hours, which is inferior to LED lighting modules without built-in power circuits. The reason is that the built-in power circuit has a shorter life than the LED, and the life of the module depends on the power circuit rather than the LED.
The LED is called "Remote Phosphor Technology" when the LEDs are configured in the module. A plurality of blue LED components are disposed in the module, and the blue light is unified into white light by using a diffusion plate containing a yellow phosphor disposed on the surface of the module. This is said to reduce the effects of brightness deviation and chromaticity deviation of the LED components.
Philips has added a variety of products using Remote Phosphor Technology to products such as downlights. In addition to products that use only blue LED components and white light through the diffuser, there are also blue LED components and red LED components to achieve white light that highlights red, and by combining RGB and white LED components. A product that dramatically changes color. The LEDs in the module are made of Philips Lumileds Lighting's small high-power LED "Rebel".
