FIELD OF THE INVENTION The present invention relates to lighting devices, lighting assemblies, lighting fixtures, and methods of using them, and in particular, lighting devices, lighting assemblies, lighting fixtures, and the like that can provide excellent heat dissipation. It relates to a method of using items. In one aspect, the present invention relates to a solid state light emitting device, and more particularly to a device that includes a solid state light emitting element and provides improved heat dissipation.
BACKGROUND OF THE INVENTION Each year, much of the electricity generated in the United States (some estimates are as high as 25%) goes to lighting. There is therefore an ongoing need to provide more energy efficient lighting.
Efforts continue to be made to develop methods in which solid state light emitters can be used in place of incandescent bulbs, fluorescent lamps, and other light generators in a wide variety of applications. In addition, where light emitting diodes (or other solid state light emitting devices) are already in use, efforts may include, for example, energy efficiency, computed color index (CRI Ia), contrast, effectiveness (lm / W), And / or continues to provide light emitting diodes (or other solid state light emitting devices) that are improved with respect to service periods.
Various types of solid state light emitting devices are well known. For example, one type of solid state light emitting device is a light emitting diode.
A light emitting diode is a semiconductor device that converts current into light. A wide variety of light emitting diodes are being used in an ever-growing wide range over the range of objectives that are still being extended.
While the development of light emitting diodes has reformed the lighting industry in many ways, some of the features of light emitting diodes have presented many challenges, some of which are not yet fully met. For example, a wide range of lighting devices, particularly LEDs, do not operate reliably at high temperatures so that they operate reliably at lower temperatures. In the case of LEDs, a heat sink is often provided and the heat generated by the LED junction is dissipated into the ambient air to keep the LED junction temperature low-typically a junction temperature of 75 ° C is the desired maximum. It is. Such a requirement, however, imposes severe limits on the amount of power that can be delivered to the LED while dissipating enough heat to meet the temperature requirement, and this often Light bulbs containing are often meant to be dull compared to incandescent and fluorescent light counters.
