Advertising projector lights are usually used outdoors. Due to the influence of the outdoor environment and ambient light, such gobo projector lights usually have a relatively large power and high lumens. This causes the projector light to generate very high heat, and the temperature rise of the projection lamp can easily cause burnout of the gobo lens, lamp beads, etc. Zhengzhou Ledy projector gobo light manufacturer, in order to extend the life of the LED projector light and reduce the occurrence of such failures, use CPU platinum-grade thermal paste and aluminum radiator to deal with the heat dissipation problem of the projection lamp.
Thermal conductive paste (silicone grease) is a new type of organic grease specially made for the heat transfer of electronic components. It is produced with a special formula and is composed of metal oxides and organic siloxanes with good thermal conductivity and insulation.
1. Good thermal conductivity and electrical insulation, shock absorption, and impact resistance.
2. Very good use stability, low consistency and good construction performance, wide operating temperature range (-50℃~+250℃, the temperature range of different models varies), heat resistance, and will not dry up at high temperatures, Does not melt.
3. It is non-corrosive to related materials, non-toxic, tasteless, and resistant to chemical corrosion.
4. Outdoor use can avoid the adverse effects of ultraviolet light, ozone, moisture, and chemicals.
Since the thermal paste has such a thermal conductivity effect, we use 25% silver content overclocking triple A1 overclocking thermal paste (A1 platinum thermal paste: thermal conductivity> 7.5W/MK) to fill the gap between the lamp bead and the radiator, so that The lamp beads are in full contact with the radiator without gaps, and the heat is effectively transferred to the radiator through the thermal paste.
For the radiator, we use dual fans for forced heat dissipation. The large aluminum radiator has a large heat dissipation area and stable performance.
2. The heat transfer performance of aluminum alloy is better than that of stainless steel, and the heat transfer performance is directly proportional to the thermal conductivity.
3. The thermal conductivity of aluminum is 204/W·(m·k), while the thermal conductivity of stainless steel is only 14/W·(m·k), so aluminum alloy has better heat transfer performance than stainless steel.
4. Thermal conductivity refers to the heat transfer through an area of 1 square meter within 1 second (1S) for a material with a thickness of 1m and a temperature difference of 1 degree (K, ℃) on both sides under stable heat transfer conditions. The unit is watts/meter·degree (W/(m·K), where K can be replaced by °C).
With the help of thermal paste and aluminum radiator, the heat dissipation problem of outdoor advertising projector light has been well solved, so that the projector light can be used for a long time without fear of damage.
Thermal grease
Thermal grease is a kind of very good thermal conductivity material, one of the materials we usually use to fill the gap between the CPU and the heat sink, this material is also called thermal interface material. Its function is to conduct the heat emitted by the CPU to the heat sink, keep the CPU temperature at a stable working level, prevent the CPU from being damaged due to poor heat dissipation, and extend its service life.Thermal conductive paste (silicone grease) is a new type of organic grease specially made for the heat transfer of electronic components. It is produced with a special formula and is composed of metal oxides and organic siloxanes with good thermal conductivity and insulation.

Advantages of aluminum radiator:
1. The thermal conductivity of pure aluminum is better than that of aluminum alloy, but the hardness of pure aluminum is lower and it is prone to deformation (you need to pay attention to destroying the radiator when installing the projection lamp).2. The heat transfer performance of aluminum alloy is better than that of stainless steel, and the heat transfer performance is directly proportional to the thermal conductivity.
3. The thermal conductivity of aluminum is 204/W·(m·k), while the thermal conductivity of stainless steel is only 14/W·(m·k), so aluminum alloy has better heat transfer performance than stainless steel.
