Solid State
What is a solid state heater cooler ? Is it use in portable coolers /warmers and air condition systems?
Is solid state cooler heater the same device as peltier? Which is use for temperature change in potrable warmers/coolers? Can this technology be employed in a portable air condition unit? If so how does it work? The application and use for this solid state device.
Is it a pair of thermocouples run in reverse.
What is a thermocouple: if you join two dis-similar metals, you get a small voltage. If you get one T/C hot and keep another one cool and connect one lead of each, you will have a simple. solid state, low-efficiency electrical generator when you put an electrical load between the two remaining wires. Putting a bunch in series and in parallel lets you increase the available voltage and amperage.
Such a "thermocouple pile" is used one the Voyager spacecraft. One pile is heated by a nuclear reaction. The cold junction is hanging out in space, radiating heat away. Very simple and very reliable.
But only about 10-15% efficient.
Doing the reverse - apply a voltage to two different thermocouple piles - causes one to get hot and the other to get cold.
Those plug-in solid-state ice-chest/warmers use that effect. They also have a fan to blow heat away from the hot junction. You need an electrical source like line voltage or a cigarette lighter (not batteries!) because it sucks a lot of power for not much effect. It is better at keeping something hot or cold than it is at GETTING something cold. i.e. it would take a LONG time to make ice cubes.
It wouldn't make a very good air conditioner because the efficiency is so bad. Freon or some other compressible gas in a refridgeration cycle is MUCH more efficient and that pulls a few horsepower. To cool a car with a peltier-effect T/Cs would suck 100 hp or more. What it can do is cool a little volume, like a few beer cans.

Leds Used In Solid-State General Lighting Global Market Forecast And Analysis (2008-2015)-Aarkstore Enterprise
General Lighting General Lighting provides the main illumination of an area. In this study, we provide a market forecast (2008-2015) and analysis of the LED component used for general lighting applications, including interior and exterior decorative and functional lighting for residential, commercial and government areas. For the purposes of this study, Directional Lighting, Supplementary Lighting and Architectural Lighting in the General Lighting category.
LEDs are used in both functional and decorative light fixtures, with an advantage of energy savings. Compared to incandescent lighting, LED-based solid-state lighting (SSL) delivers visible light with reduced heat. In addition, its solid-state nature provides for greater resistance to shock, vibration, and wear, thereby significantly increasing its lifespan
Market Forecast Functions:
· Consumption Value ($, Million)
· Quantity (number/units)
· Average Selling Prices (ASP $, each)
The market data covers LED packaged component used in SSL – General Lighting systems (illumination lamps, devices and fixtures). The market data are segmented into the following geographic regions, plus a Global summary:
· Americas (North America, Central and South America)
· EMEA (Europe, Middle Eastern countries, plus Africa)
· APAC (Asia Pacific)
Market data for the following color and lumen types (brightness) are also segmented:
· White: Conventional LEDs
· White: High-Brightness (HB-LEDs)
· RGB/Other: Conventional LEDs
· RGB/Other: High-Brightness (HB-LEDs)
The global LED solid-state lighting (SSL) General Lighting market, in this report, is segmented into the following two (2) major application categories:
· Residential, Commercial & Government EXTERIOR
§ Landscaping
§ Pool/fountain
§ Buildings
§ Bridges/Tunnels
§ Streetlights/Parking Lots
§ Airstrips/aviation
§ Directional/Spot Lighting
§ Architectural Lighting
§ Other General Lighting
· Residential, Commercial & Government INTERIOR
§ Retail/Store Display Cases
§ Grocery/Restaurant Food displays & similar
§ Art Display, Artistic/Mood Lighting
§ Stage Lighting
§ Rooms, Hallways, Stairways
§ Directional/Spot Lighting
§ Architectural Lighting
§ Other General Lighting
SSL General Lighting Market Forecast In 2008, the global consumption number of component-level LEDs, which are used in solid-state lighting (SSL) general lighting applications, reached over 1.2 billion units. The consumption (use) is forecast to increase to 3.7 billion LEDs by 2015. Exterior applications, driven by maintenance/labor, safety/security and “Green-Tech” issues will continue to dominate the use of LEDs in solid-state general lighting.
