What is the impact of poor heat dissipation on ufo led high bay light?

Sep. 08, 2020

Everyone knows that UFO LED High Bay Light are cold light sources. Therefore, many customers think that LED high bay lights will not be as hot as incandescent lamps. In fact, this is wrong. LED high bay lights still generate heat. When electricity is converted into light energy, it is partially converted into heat energy, thus generating heat. What are the possible consequences of poor heat dissipation of UFO LED high bay lights?


If the heat dissipation of the UFO LED high bay light is not good, the junction temperature of the LED chip will be rapidly increased. If the LED high bay lamp is working in a high temperature state for a long time, the life of the LED high bay lamp will be shortened. Therefore, LED high bay light manufacturers are trying to solve the problem of heat dissipation of LED high bay light, and some manufacturers neglect the heat dissipation problem of lamps in order to manufacture low-priced LED lamps, so the lamps will have problems soon.

The most important thing in UFO LED lighting is the chip and heat dissipation. The heat dissipation will directly affect the stability of the luminaire and the service life of the product, while the LED chip can bring better illuminating effect and more efficient luminous efficiency. 


The main effects of poor heat dissipation on LED lamps are as follows:


1. Reduced life

Poor heat dissipation directly leads to a decrease in the service life of LED luminaires. Since LED luminaires convert electrical energy into visible light, excess electrical energy is converted into thermal energy during this period. If the design of the heat dissipation structure of the LED lamp is unreasonable, this part of the heat energy cannot be quickly eliminated. Therefore, since the LED package is relatively small in volume, a large amount of heat energy will be accumulated in the LED lamp, resulting in a decrease in life.


2. Affect the quality of lamps

When LED lamps with poor heat dissipation are used for a long time, some materials are easily oxidized. As the temperature of the LED lamps rises, these materials are repeatedly oxidized at a high temperature, the quality is lowered, and the life is shortened.


3. Easy to cause failure

When the temperature of the LED lamp rises, the impedance of the electric power increases, causing the current to increase, and the increase in the current causes the heat to rise. In this way, the accumulation of heat, more and more, will eventually cause the electronic components to overheat and damage, causing product failure.


4. Luminaire material deformation

LED luminaires are made up of multiple parts, different parts of which are made of different materials, which have different heat resistance. When the temperature rises, some of the material will bend due to overheating. If the spacing between adjacent components is too small, both will be crushed and severely damaged.


The poor heat dissipation of LED lamps will cause many problems. The problems of these components will lead to the performance degradation of the entire LED lamps and shorten the service life. Therefore, LED heat dissipation technology is an important technical problem. While improving the LED power conversion rate, the LED heat dissipation structure design should be more effective, so that the LED lighting fixtures can get rid of the heat dissipation troubles.


How to enhance the heat dissipation of UFO LED High Bay Light?


Solve the heat dissipation of LED high bay light, mainly from two aspects, LED mining lamp cooling and LED chip cooling. The heat dissipation of the LED chip is mainly related to the selection and process of the substrate and the circuit. We mainly introduce the heat dissipation problem of LED high bay light. Different UFO LED high bay light will use different thermal conductive materials according to customer needs and costs. For example, our Lampshining UFO LED high bay light manufacturers have the following types:


1.Aluminum heat sink fin

This is a common way to dissipate heat, using aluminum fins as part of the enclosure to increase heat dissipation and lighter weight.


2. Using a fluid dynamics shell

The use of a heat-dissipating housing design creates convective air for enhanced heat dissipation.


3. Graphene cooling

This is our latest Graphene UFO LED High Bay Light, Using new graphene material, with light weight and small volume, and the heat dissipation effect is better.

At present, the low-priced high bay light on the market use pure plastic shell mining. This type of high bay light basically have no heat treatment and the effect is very poor. Performance and longevity are also not very good, the only feature is the low price. Therefore, you need to pay attention to avoid these luminaire manufacturers when purchasing.
