When the LED Light is operating normally.

led high bay lights, high bay lights,


The chip has little heat, good conduction, sufficient heat dissipation, and a low handle temperature. It's a good cooling system and the only "downside" can be a waste of materials.

So, why is the low-temperature heat sink not necessarily a good one? The problem is mainly in the conduction of heat when the heat the generated heat cannot be transported smoothly to the dispersed part, the accumulation of heat in the vicinity of the heat source, the heat transfer to the sink Thermal temperature of the handle is not high.

If there are impurities under the PCB, there is no good contact with the heat sink, the heat cannot disperse, concentrated in the chip. It's not hot outside, in fact, the chips are already hot!

Touching the heat sink is very hot. It must be bad.


If the touch of the heat sink is very hot, the cooling the system is certainly not good or the cooling capacity of the heat sink is insufficient, there may be either the Mavericks drawbar trolleys; the effective heat dissipation area is not enough, the heat cannot be quick with the ambient air for heat exchange, cause a Light with the difference in the air the temperature in the heat dissipation, so very hot.

The volume or surface of the heat sink is insufficient, the heat of the chip cannot be sent in time, and it will cause a very hot touch.

Some heat sinks seem very thick, but the "effective heat dissipation zone" is not enough. A set of cooling systems, in which a portion of the heat sink can be fully exposed to the ambient air and the air can quickly leave freely, can be called "effective heat dissipation area". Other materials that cannot be free and the area of ​​total air contact, at best, can only be thermal capacity materials or a heat radiation zone.

So, how to systematically identify the heat dissipation of LED Lights?

So, how to systematically identify the heat dissipation of LED Lights? Since we cannot directly measure the junction temperature, is there an indirect way of knowing the junction temperature? Fortunately, as the temperature of the LED junction increases, the luminous flux will decrease. Then, as long as we measure the illumination change of the Light at the same position, we can reverse the junction temperature change.   HOW? 1, choose a place that is not disturbed by the outside light, preferably at night, turn off the other lights. 2, cold light immediately measures a position of illumination, records the reading at this time is "cold illumination". 3, Keep the Lights position and illumination unchanged, the Lights work continuously. 4, half an hour later, reads the luminance value here, note that the reading is "illumination in the hot state" 5, if the difference between the two values ​​(10 ~ 15%), the cooling system of t...

Why LED Lights need to pay attention to heat dissipation?

Why LED Lights need to pay attention to heat dissipation? Why should led lights pay attention to heat dissipation? The traditional Light does not need that? CFL, turn on by heat, and it does not matter if the temperature is not hot enough to melt the glass; The halogen light is hot, but it has no effect on efficiency and life. It does not matter if it's not hot enough to melt the parts; The tube temperature of the metal halide Light is very high, unless the high power usually does not require much attention to heat dissipation. Why should LED Street Lights pay attention to heat dissipation? "This is a high-power metal halide Light, if the heat is not good, can lead to the melting of the electrode, so it has a very thick electrical connector, and some will be in the water, heat dissipation. " Why LED afraid of heat? Each time how many watts for led Lights, because its scary heat, therefore, causes heat dissipation. LED is a semicon...

What is the relationship between the junction temperature and the lifetime of the LEDs?

What is the relationship between the junction temperature and the lifetime of the LEDs? "The junction temperature of 105 degrees, the flux has decreased rapidly to 70%, and then the life of the LED Light is about 10 thousand hours, if the temperature control at 55 degrees, LED life can go up to 'to 100 thousand + hours.' So we need to find a way to calm ourselves down and let them LEDs dissipate the heat you have. So, how do you get rid of the heat? Principle of heat dissipation LED: Heat dissipation to modes 3: conduction, convection, and radiation. Conduction: the path of heat from the upper part of the object along the body to the lower part of the temperature; Factors Affecting Heat Transfer: 1. Heat sink material 2. Heat dissipation structure; The closer the material is, the faster the heat transfer and if the two materials touch a little bit, the thermal conduction is blocked, and it is the thermal resistance. At this point, we ...
