New LED Automotive Lighting

American Bright have launched a series of automotive LED lights that serve as low power, high brightness replacements for the T10 incandescent bulbs. As with all LEDs, they give off minimal excess heat, and no infrared, ultraviolet, or other harmful radiation.

The T10 LED bulbs are available in either 12 or 24 volts, and 0.5 or 1 Watts. They can be bought in four different colours. These are Amber, White, Cool White, and Warm White. Depending on all of these variables, the bulb will output light ranging from 37 to 105 lumens.

If you’d like to know more about the T10 LED bulbs, please don’t hesitate to contact us.

Green Fingers Under Purple Skies

Light comes in three parts – red, blue, and green. It’s a bit more complicated than that, but this will do for now. When something appears white, it is because it is reflecting all three colours, and absorbing none. At the other end of the scale, if something appears black, they are absorbing all of the visible light, and reflecting none of it back. All colours in all things lie somewhere between these extremes, absorbing some light, and reflecting back part of a specific bracket which is what gives us colour.

Plants usually reflect the green part of the light spectrum, hence their green colour. They also have chlorophyll in their leaves, which allows them to convert light into energy for growth. Chlorophyll comes in several different varieties, but the two you will find in green plants everywhere is chlorophyll a, and chlorophyll b. Chlorophyll a is what allows the plant to convert energy from the ultra-violet end of the light scale, and chlorophyll b converts energy from the infra-red end of the light spectrum.

This is why you will often find LED lighting designed for horticulture gives off a purple light. They are providing light in both the blue and red parts of the spectrum that the plant needs for maximum growth potential.

The other thing to consider when looking at horticultural lighting is the amount of light they give off. It won’t make much difference if you’re using the right colour light, if the beam is too weak to matter. This is rated in Lumens (lm). An old 60 watt filament bulb, for example, would give off around 800-850 lumens, or to talk the technical talk, around 13-14 lumens per watt (lm/W). In comparison, an LED light that gives off the same amount of lumens, would only need to be rated at about 11.5 watt, so barely 20% of the power needed.

As well as the obvious power savings, LED lighting technology also means that we can generate the same amount of light as an old bulb, while giving off just a tiny fraction of the heat a filament bulb generates. This is part of how we can generate the same amount of light with a far lower wattage – a far lower energy loss due to heat waste.

American Bright Optoelectronics Company has recently launched a new range of horticultural LED strip lighting, making them the first company to market an efficient and industrial scale IP67 grow light system. It is suitable for use in both vertical and horizontal applications, and is available in both DC and AC format, depending on length and voltage. The maximum length of the lighting strips can be up to 98 feet, or 30m. At this length you are limited to a 240 volt AC power supply. The next length is 65ft, or 20m, which can be lit using a 120v AC power supply, and the final, shortest length available is just 10ft, or around 3m. This is the maximum length you can use if planning on using a DC power supply.

Technological Fusion

Tangio continues to lead on the cutting edge of Force Sensing Resistor technology with their latest product, Fuzion, which combines the different methods of force sensing.

Force sensing resistor technology comes in two variations. Resistive FSRs use a conductive layer in the sensor itself, which requires pressure to be applied. The more pressure applied to the sensor, the lower the resistance. The majority of typical force sensing resistors are of the resistive type.

The other version of force sensing technology is one often seen in technology like smartphones. A capacitive FSR works by detecting electrical currents, and basing the resistance on the current detected. This even works with the minute electrical signals running through your body, and doesn’t even require touch, only proximity.

Fuzion combines both of these into a single unit, allowing for unprecedented control over activation. In the demo video below, you can see how the sensor detects not only pressure applied (green lights), but also when a user’s finger approaches the device (orange lights).

Fuzion was created so it only needs one sensor which is capable of handling both methods of detection, and only one interface, saving you both time and money in the supply chain.

Ohmite Launches Aluminum Housed Wirewound With Flying Leads

Ohmite is expanding it’s popular line of Aluminum housed resistors. The Ohmite ARG series is a high wattage wirewound resistor sealed in an aluminum extrusion. The aluminum housed design is appealing to power engineers for multiple reasons. Key design aspects include a sealed design, flying leads, and heatsinking ability. The ARG series is capable of dissipating 150-400 watts depending on resistor length and is available in 6 sizes. Ohmite offers other aluminum housed resistors and should be considered in high power industrial applications. Ohmite distribution partners can expect to receive the NPI package shortly on the ARG Series.

Thermoelectric Cooler Technology

Thermoelectric Cooler and Thermo Generating Module technology is based on two principles, the Seebeck effect, and the Peltier effect. The first of these shows how we can use a temperature differential to create an electrical charge, and the second, how we can use an electrical charge to create a temperature differential.

When heat is applied to one of the conductors or semiconductors, this creates a flow of heated electrons towards the colder side. This in turn generates a tiny electrical charge, in the microvolts range per kelvin of temperature difference. Connecting devices using this Seebeck principle allows you to maximise the voltage by connecting the devices in series, or to increase the current by placing the devices in parallel with each other.

On the other side of the equation, if you were to instead apply an electrical current through a junction between two conductors, you would also see a transfer of heat passed to the cooler of the components. A typical heat pump using peltier technology uses several junctions in series, some of which gain heat, and others which lose heat as a current is applied.

You will find thermoelectric cooler technology in many places where temperature has to be controlled, from refrigeration units, all the way up to satellites. When used in satellite technology, TECs are used to help maintain a temperature suitable for the satellite’s internal components to still function.

Back down on Earth, thermoelectric coolers are used to help regulate temperatures in refrigeration units, such as those used to carry frozen goods from country to country, or even the freezer rooms in the back of restaurants. In this instance, it is especially important that the TEC’s output temperature is well regulated, as this could determine if the item using the thermoelectric cooler is compliant with a number of food safety standards including ISO9000, and HACCP.

We supply thermoelectric coolers, and thermo generating modules manufactured in Russia by Kryotherm. Click here to view the Kryotherm website, and if you’d like any information or pricing about any of their products, please, give us a call.

Davies to the Rescue

Elon Musk, billionaire tech entrepreneur, made use of Davies Molding handles in his latest device.  In response to the July crisis that saw children trapped in a cave in Thailand, Musk and his engineering team invented a “kid-size” submarine designed to rescue the boys soccer team from the Thailand cave.  Musk shared pictures of the submarine featuring Davies Molding two-shot pull handles on Twitter (see above).

The two-shot pull handles provide a non-slip grip making them durable for a mission intense as this one.  These handles are molded in the Davies plant with a glass reinforced Nylon substrate and an overmold Thermoplastic Elastomer rubber.

It’s always exciting to see a Davies Molding product in use, especially with a high-profile event as this one.  To read more about Elon Musk’s submarine, please visit @elonmusk on Twitter.
