led lighting fixtures is the collective name of LED lamps and lanterns, refers to the light transmission, distribution and change the light distribution of the LED light source apparatus, including all of the LED light source in addition to all the zero, parts needed to fix and protect the LED light source, as well as the line necessary to connect with the power supply accessories. With the further maturity of LED technology, LED will make more and better development in the field of interior lighting design and development.
21st century interior lighting design will be the mainstream of LED lighting design, while fully reflecting the energy-saving, health, artistic and humane lighting trends, becoming the dominant interior lighting culture. In the new century, LED lighting fixtures will certainly light up everyone’s room, change everyone’s life, and become a great change in the development and design of lamps and lanterns!

The supply voltage is too high

If the supply voltage is higher than the nominal voltage of the LED lamp, it will lead to excessive power, generating more heat, causing a higher temperature rise. This is one of the most common reasons for LED lights to heat up.

poor heat dissipation

If the LED lamp poor heat dissipation conditions, such as heat sink area is too small, cooling fan power or blocked ventilation holes, etc., can not be timely heat, will also lead to heat problems.

High ambient temperature

If the LED lamp is located in the ambient temperature itself is high, then the heat generated by the LED lamp operation is more difficult to dissipate, which may also become one of the causes of heat.

low luminous efficiency

Lower luminous efficacy of the LED will have more electrical energy into heat, which also means higher heat generation, which can easily lead to high temperatures.

large drive losses

If the LED drive circuit loss is large, then more electrical energy will be converted into heat, increasing the total heat of the LED lamp, resulting in a certain temperature rise.

sealed space

If the LED lamp is installed in a relatively closed space, then the heat generated by the LED lamp is more difficult to dissipate through air convection, easy to accumulate in the space, resulting in local overheating.

component damage

If the LED lamp thermistor or other temperature control components are faulty or damaged, can not work properly, then can not effectively control and protect the temperature of the LED, will also cause more serious heat.

LED lamp temperature control components are mainly.

thermistor

used to detect the temperature of the LED, when the temperature rises to a certain threshold, its resistance value will change, thus causing corresponding changes in the LED driver circuit, such as reducing the input power to control the temperature of the LED.

temperature sensor

used to accurately measure the LED temperature, and the temperature signal back to the driver circuit or other temperature control system. Driver circuit according to the temperature sensor signal to take appropriate measures to control the LED input power and working state, to ensure that it works within the normal temperature range.

Overtemperature protector

used to monitor the temperature of the LED, when the temperature exceeds a safe threshold, overtemperature protector will mechanically or electrically disconnect the LED power supply circuit, stop the LED work to prevent permanent damage caused by overheating.
If these temperature control components fail, will not be able to properly monitor and control the temperature of the LED. LED will continue to work at a higher power, generating more heat and can not be effectively dissipated, the temperature will continue to rise to the degree of permanent damage to the characteristics and life of the LED. Severe cases may even lead to a significant shortening of product life or overheating caused by fire and other consequences.

Therefore, the normal working condition of the temperature control system and temperature control components of LED products is crucial to the safety and life of the products. We will carry out strict quality control and testing of these temperature control systems and components during the product design and production process to ensure their high reliability and stability, which can effectively detect and control the working temperature of LEDs, minimizing product failure and damage caused by overheating.

The following measures are helpful to improve the thermal management of LED lamps and control the working temperature of the products.

increase the area of the heat sink.

Increase the heat sink can significantly increase the heat dissipation area, thereby accelerating the speed of heat dissipation and more effectively conduct or convection out of the heat generated by the LED. This is one of the most basic measures of thermal management of LED lamps.

Use powerful cooling fans.

The installation of cooling fans can produce forced air flow to help heat transfer from the heatsink faster. Especially in the case of high ambient temperature or poor thermal conditions, cooling fans can play an important role.

choose high luminous efficiency and low heat loss of the LED.

high luminous efficiency LED luminous efficiency is higher, can produce higher luminous flux under the same driving conditions, which means less power into heat, thus reducing the overall heat generation. This can reduce the source of LED thermal management pressure.2023 05 04 20 07 27 1024x1024

Optimize the drive circuit.

Efficient LED drive circuit can maximize the input power into light energy, reducing the heat generated by drive losses. Optimize the drive scheme and improve the drive efficiency is also one of the effective measures to reduce the heat of LED lamps.shopilycfceb7f4 46af 4c73 a8d1 0c5df608d776 1024x1024

Use more efficient LED light source to improve its luminous efficiency.

LEDs with higher luminous efficiency can produce higher luminous flux under the same driving conditions, which means less power is converted into heat, so the overall heat generation is also lower. This can reduce the thermal management pressure of LEDs from the source.

The use of more efficient LED driver.

Efficient LED driver circuit can maximize the input power into light energy, reducing the heat generated by drive losses. Optimize the drive scheme and improve the drive efficiency is also one of the effective measures to reduce the heat of LED lamps.shopilyabfea650 4cda 400e 895f 2a129a5836b5 1024x1024

Select applications with low ambient temperature.

High ambient temperature will make it more difficult for LEDs to dissipate heat, which in turn increases its own temperature rise, so the use of LEDs in applications where the ambient temperature is low can better control its operating temperature.
