LED: does it really heat up?


LED: does it really heat up?

LED lights are rented to be environmentally friendly, less energy consuming. They have an impressive lifespan, but it seems that the idea that LED lamps to give off heat still persists in people's minds. So, is the LED light as hot as an incandescent bulb?

The incandescent lamps are definitely hot!

Incandescent lamps are known to heat strongly during the diffusion of light. There was a time when it was good to wait for a moment before touching or changing your light bulb - for fear of burning yourself - when you had just turned it off. This happens because the tungsten wire inside heats up as electricity is transformed. Thus, a certain amount of heat is produced during the process that leads to lighting. With an incandescent bulb, 90% of the electricity is used to produce heat, only 10% is used for light scattering. So a lamp that stays on for a certain period of time will certainly explode with heat.


Therefore, the production of this heat has the effect of:

  • ·         Reduce the life of the bulb ( 800-1200 hours )
  • ·         Decrease the electrical resistance of the filaments by being heated.
  • ·         Increase electricity consumption and cause frequent replacements


LED lights do not heat the same way

Let's say it clearly, LEDs generate heat ... Like any device or anything that consumes electricity. It's physics. However, LEDs do not create heat in the same way as incandescent lamps. In fact, you can easily unscrew an LED that has been lit for days! You will not be burned. When electricity passes through the semiconductor, there is hardly heat that emerges. It is almost impossible to feel that. This is due to the nature of the technology. In short, LEDs could not create a fire hazard or burn someone. They produce light coldly.


This helps on many levels:

  • ·         LEDs are suitable for offices
  • ·         Light production is energy efficient
  • ·         LED lights are ecological

LED vs. Fluorescent

LED vs. Fluorescent How does an LED bulb work? An LED - a light emitting diode (abbreviated as LED in French, but more commonly known as LED for Light Emitting Diode) - Thus, an LED the bulb has no filament, unlike an incandescent bulb, but consists of layers of several semiconductor materials that are aluminum nitride and gallium phosphide. These materials, with no resistance to current, prevent energy loss while creating light. In fact, the excess electrons encounter positively charged atoms, when the electric current passes through the semiconductor layers, which releases energy in the form of light. Advantages and disadvantages of an LED bulb? The major advantage of an LED bulb is undoubtedly its high energy efficiency because no energy is lost as seen previously. Thus, with LED technology, the operating time of a light bulb is around 15,000 to 50,000 hours, which is 35 to 50 times longer than a standard light bulb. In the long run, this translates into low maintenance...

What do IP protection standards mean?

What do IP protection standards mean? We often see these two associated letters - IP - at the level of electronic devices (smartphones, lights ... etc.). But what are these two letters often followed by two numbers? Explanations. IP standards The IP protection standards , in English, "Ingress protection" comes from an international standard set up by the IEC (International Electrotechnical Commission) relating to waterproofing. They appear for the first time in 1989. You should know that this code corresponds to the degrees of protection that justify a material. In fact, if a luminaire is used outside, it is good that the latter has several protections that allow it to withstand external aggressions, given its use. These standards are thus present to indicate to the buyer the protection available to the product he wishes to acquire. It is in the format: IP 67. Each element will be pronounced in this way: "IP six-seven”. Sometimes, we can also resort to the ...
