The LED light source is the difference between efficiency and performance LED lighting lamps and lanterns

The LED light luminous efficacy of light flux is refers to the bare lamp ( Has not yet loaded into lamps and lanterns state) The luminous flux. The integration of LED light source can be integrated LED lamp or LED module, integrated LED lamp or half integration LED module or not integrated LED lamp or LED module. LED lamps and lanterns efficiency - expression type of molecule - - - Flux is refers to the light source into the lamps and lanterns, at the same time use the LED control device or LED control device of power supply after the luminous flux from lamps and lanterns. Which LED power supply control device or LED control device can be integrated, built in or freestanding. Using LED lighting lamps and lanterns can use reflector, diffuser or lens. In the light of lamps and lanterns is likely to be a collection of individual light or more light, but due to the interaction of heat and electricity efficiency loss, and the efficiency of the optical system of lamps and lanterns, the luminous flux of LED lamps and lanterns is not equal to the LED lamp flux or the simple accumulation. LED light source table type and the denominator in the LED led lighting lamps and lanterns of effectiveness of the denominator meaning is not the same. For example, for the integration of LED modules, LED light source of electrical power consumption by only refers to the power consumed by a LED module, LED control unit consumption of power. The consumption of electric power of LED lamps and lanterns efficiency refers to the input power of lamps and lanterns, including not only the LED light source, include LED power consumed by a control device. LED lamps and lanterns of electrical power consumption is greater than the LED light source of electrical power consumption. Efficiency of LED lamps and lanterns and LED light photosynthetic efficiency, the relationship between by flux involved and the scope of the electrical power is different, caused the LED light source efficiency is different from the LED led lighting lamps and lanterns, light lamps and lanterns of photosynthetic efficiency than efficiency. One is LED into the lamps and lanterns, junction temperature rise, high light output ( Heat loss) ; Secondly, light source into the lamps and lanterns, and USES the LED control device or the power supply after the loss of system; Third is the loss of the light after lamps and lanterns of optical system, the efficiency of lamps and lanterns, Light loss) 。 So the efficiency of the light source and the efficiency of lamps and lanterns simply don't mix, high lighting effect does not represent the efficiency of lamps and lanterns must be high, also look at the light source is processed into lamps and lanterns is in the process of problem such as heat dissipation problem whether can very good solution, to solve the possible problem, in that case, the lamps and lanterns of highly efficient light source to make it efficient.
