T j(Junction Temperature).
The optimized heat sink design to ensure the LED junction temperature is below60 degrees.
LED junction temperature(°C).
The following equations can be used to calculate the junction temperature of the products.
Maximum junction temperature: 175 C.
In summary, the key to extending the life of the 600x600 LED Panel Lights is to reduce the junction temperature.
Maximum junction temperature: 140 C.
To sum up,the key to extending the life of the Square LED Panel Lights is to reduce the junction temperature.
(protect chip junction temperature T j≤125℃).
Junction temperature 95℃ when the Square LED Panel Lights life has 20,000 hours;
Work to produce heat,control the chip's junction temperature within a reasonable range.
Reducing the junction temperature of the LED chip requires reducing the thermal resistance of eac….
With the support of semiconductor technology, semiconductor thermocouple sensors,PN junction temperature sensors and integrated temperature sensors have been developed in this century.
Reducing the junction temperature of the LED chip requires reducing the thermal resistance of eac…[Jun 07, 2017].
Usually these LEDs are mounted on heatsinks with suitable size orspecial printed circuit boards so their junction temperature can be kept low enough for them to function normally.
Reducing the junction temperature of the LED chip require….
The heat conductive plastic is the preferred material for solving the heat dissipation of the LED chip, andit can derive the heat generated by the LED light emission in time to lower the junction temperature.
Reducing the junction temperature of the LED chip requires.
Overview: LED street lamp temperature is too high will affect the life of LED lamps, the industry that the lower the better,so LED life and junction temperature showed an inverse effect, the higher the balance of the higher temperature. .
If the junction temperature is 105℃, brightness down to 70% of the Square LED Panel Lights life of only more than 10,000 hours;
LED is very sensitive to the temperature impact,in general, the junction temperature of 125 degrees Celsius below the LED can be avoided performance or even failure.
And junction temperature reduced to 75℃, life Can be up to 50,000 hours, 65℃ when the life can be extended to 90,000 hours.
The current LED thermal technology problem is the LED junction temperature limit, under normal circumstances the maximum temperature of 125 degrees Celsius;
And junction temperature reduced to 75℃, life Can be as long as 50,000 hours, 65℃ when the life can be extended to 90,000 hours.
In general, the LED luminous efficiency and service life declines withthe increase of the junction temperature, when the junction temperature of 125℃ above, the LED can appear even failure.
If the junction temperature of 105℃, brightness down to 70% of the 600x600 LED Panel Lights life of only more than 10,000 hours;
The basic structure of the LED is a semiconductor PN junction, when the current through the PN junction, the added power and not all converted into light energy, most of the heat in the form of PN junction, the PN junction temperature rise, called Junction temperature.
If the junction temperature of 105℃, brightness down to 70% of the 300x300 LED Panel Lights life is only more than 10,000 hours;
We will first make a guess at the junction temperature, at 125ºC We must find what the maximum drain current is at 125ºC first.
When the junction temperature of the LED exceeds the high temperature that the device can withstand, the light output characteristics of the LED will decay forever.
