The present invention relates to a Cool and efficient light providing consistent, constant, controlled, wavelength specific and directional illumination. The cool efficient light (CEL for short) emits the wanted wavelengths of light directionally while dissipating the heat through the reflector. The light output can be smooth and not pulsed leading to a higher ratio of light over time. Choosing the right emitters for the intended use it is possible to emit wanted wavelengths of light in the wanted place with minimal extra radiation such as heat or UV rays.
The device is comprised of the following:
A. Wavelength specific emitter
B. Heat sink and reflector
C. Direct current power source
D. Load resistor OR current limiting device
E. Frame
F. Cool Efficient Light
G. Electrical conductor
The Cool Efficient Light (F) device is an electric device that emits desired wavelengths of energy including but not limited to visible light, such as a lighting fixture or light, and may be anywhere from very small, or terribly large.
The wavelength specific emitter (A) is an electronic device emitting specific wavelength(s) radiation including but not limited to visible light. The emitter (A) could include future yet to be invented or conceived emitters and current emitters such as but not limited to LED, light emitting diodes, and other devices that emit specific wavelength(s). The emitter (A) will emit its energy when some electricity is applied.
The heat sink and reflector (B) provides adequate heat dissipation for emitter function while reflecting usable energy in the desired direction. The heat sink and reflector (B) can be constructed of any materiel that provides enough heat dissipation for the emitter to operate including but not limited to aluminum. A polished surface is recommended to reflect as much energy as possible. The heat sink and reflector (B) can be constructed out of multiple pieces or out of one piece but should be assembled with an appropriate thermal compound or something in way to ensure proper thermal conductivity.
A more complex load resistor or current limiting device (D) may be used in order to control the release of energy. Smaller and more efficient components could allow for a smaller more streamlined frame (E). The direct current power source (C) and the load resistor or current limiting device (D) could be integrated as one unit. An onboard control computer could be added to control modulation of different emitters on the same light or to control the light over time. Furthermore lights could be controlled from a central device. Multiple emitters could also be used. Emitters that have multiple colors on the same device could also be used.
The cool efficient light (F) drawn has three heat sink and reflectors (B) but the cool efficient light (F) can have any number of any size heat sink and reflector(s). The frame (E) can be adjusted to any size or shape. Multiple emitters (A) can be attached to the heat sink reflector (B). Different or multiple direct current power sources (C) can be used. The load resistor or current limiting device (D) is connected between the wavelength specific emitter (A) and the direct current power source (C) to control the amount of electricity in the emitter (A).

Wavelength specific emitter(s) (A) can be place on the heat sink reflector (B) so the desired output is directed forward while the heat generated by the emitter(s) is dissipated by the heat sink reflector (B). The heat sink reflector(s) (B) with attached wavelength specific emitter(s) (A) can be fastened to the frame (E) along with the direct current power source(s) (C) and the load resistor(s) or current limiting device(s). Conductor(s) (G) connect the direct current power source(s) (C) to the wavelength specific emitter(s) (A) through the load resistor(s) or current limiting device(s) (D). All the components do not need to be connected to the frame or to each other in order to function as long as they are connected via the conductors (G). The direct current power supply(s) (C) and load resistor(s) or current limiting device(s) (D) could be in a separate frame (E) than the heat sink and reflector(s) and wavelength specific emitter(s) (A) as long as they are connected with conductor(s) (G).
The direct current power source (C) supplies electricity through the load resistor or current limiting device (D) to the wavelength specific emitter (A) that is attached to the heat sink reflector (B) and energy is emitted out of the wavelength specific emitter (A). The heat generated by the wavelength specific emitter (A) is dissipated by the heat sink and reflector (B) while the specific wavelengths produced are also directed by reflection.
When the direct current power supply (C) is connected to the wavelength specific emitter (A) and the load resistor or current limiting device (D) via the conductor (G) the electricity causes the wavelength specific emitter (A) to emit light that is reflected and heat that is dissipated through the heat sink and reflector (B).
Attach the wavelength specific emitter(s) (A) to the heat sink and reflector (B) in a way that ensures good thermal conductivity between devices. The heat sink and reflector should be made from a materiel that can dissipate enough heat from the wavelength specific emitter(s) (A) and reflect any usable energy in the desired direction. The wavelength specific emitter(s) (A) should be chosen for the required output and an appropriate load resistor or current limiting device (D) is placed in line with the direct current power source (C) and the wavelength specific emitter (A). The conductor (G) should be of sufficient size or capacity to safely conduct the electricity between the components. The direct current power source (C) should be rated to handle the load with proper safety factor. The components should be connected in accordance with manufactures specifications.
The direct current power source (C) and load resistor or current limiting device (D) can be combined. The direct current power source (C) and/or load resistor or current limiting device (D) can be moved to a separate unit. Additional devices can attach to the heat sink and reflector (B) to increase thermal mass such as but not limited to a water cooling system or fans. A switch or switches may be added for control.
The cool efficient light (F) works as long as the direct current power source (C) is supplying electricity. The cool efficient light (F) is used where efficiency is needed as well as wavelength specific output. The cool efficient light (F) can be used for any lighting application.
The cool efficient light (F) can be used for but not limited to fish tanks, horticulture, plant growth, live entertainment, still photography, desk lamps, photo therapy, human cell repair, concerts, film, TV, buildings, eco-friendly lighting, mobile homes, cars, military, parties, corporate events, landscape lighting, marine lighting, and space exploration.

Common lighting devices (including other LED lights) emit a wide range of radiation, including heat, often not needed for the intended purpose, illumination; and this energy is often pulsed at a high rate so it appears to be consistently on to the human eye but causing a drop in needed luminance at a specific wavelength and over a finite amount of time and space in relation to power consumption. Furthermore the heat generated is often removed by a fan or other method leading to more power use and heat generation.
The purpose of a lighting instrument is to turn electrical energy into electromagnetic radiation in the form of needed light efficiently as possible.

NOTES
How to build and use RTG CEL

There are three main components to RTG CEL.

1. Wavelength Specific Emitter. This device will emit a specific color of light when a specific amount of electrical energy is applied. Often but not limited to LED. The idea is to only emit the wavelengths or colors of light that you need. LEDs are good for this because they usually have a very finite and specific color range per emitter. Keep in mind choosing the proper spectrum or color of light is very important for maximum efficiency.

2. Load Limiting Device. You can't just hook up any emitter to any source of electricity. Without a device to control the electrical current the emitter would draw too much power and burn up. In order to find the right kind of load limiter we will need to look at the electrical characteristics of the emitters and the type of electricity. There are many options to control the electricity such as LED drivers and other digital devices but the smoothest and simplest way to drive any LED is with a properly rated resistor. For instance if we are using a 12 volt direct current electrical system and a 10 watt deep red LED that has characteristics of 10.5 volts at .7 amp then we would need a 10 watt 2.2 ohm resistor in between the power source and LED to ensure proper function. Here is a link to an awesome calculator! http://led.linear1.org/led.wiz

3. Heat sink/Reflector. This is the key to RTG CEL! All electrical devices give off heat as a by product to their function. Using a reflective and thermally conductive materiel such as aluminum to dissipate the heat while concentrating the beam of light will further increase efficiency and give structure to the CEL.

LEDs and resistor values need to be calculated to be effective.

RTG CEL is a light delivery system and any number of light emitting devices can be used.
