DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figure 1 - Figure 3 The utility model provides a technical scheme: a heat insulation type reflector cup, comprising: product parameters and material selection:

[0022] The heat insulation type reflector cup 100 is specially designed for a certain type of lamp, and the cup body 1001 has a diameter of 80mm and a depth of 60mm. The cup body 1001 is sequentially provided with multiple layers from inside to outside.

[0023] The inner heat insulation layer 100101 is made of ceramic fiber material and has a thickness of 3mm. By virtue of the low thermal conductivity of ceramic fiber, the heat from the light source can be effectively blocked from entering, and the internal structure and optical performance of the reflector cup 100 are protected.

[0024] The vacuum layer 100102 between the inner heat insulation layer 100101 and the outer heat insulation layer 100103 is extracted into vacuum through a special process, and the thickness is accurately controlled at 5mm, which maximally reduces heat conduction and further reduces heat transfer. The outer heat insulation layer 100103 is made of polyimide film and has a thickness of 0.5mm, which can effectively prevent heat from being emitted to other components of the lamp, and avoid damaging the surrounding components.

[0025] The connecting sleeve 100105 is made of aluminum alloy and has a thickness of 2mm, which not only has good thermal conductivity, but also can ensure the overall structural strength.

[0026] The heat dissipation fins 100104 are designed as arc-shaped strips, and the number is 20, which are completely attached to the outer heat insulation layer 100103 and the connecting sleeve 100105. The air gap width between the heat dissipation fins 100104 is 7mm, which ensures smooth air flow and is beneficial to heat dissipation.

[0027] The fixing sleeve 2001 of the connecting head 200 is tightly matched with the top opening of the cup body 1001, and the inner wall of the fixing sleeve 2001 is provided with threads 2002, which are matched with the lamp holder to ensure that the reflector cup 100 is installed firmly. The inner heat insulation layer 100101 is provided with a protrusion 1002 on the side wall, and the surface is coated with an aluminum film, which can reflect and focus light, improving the lighting effect of the lamp.

[0028] Installation process:

[0029] During installation, the reflector cup 100 is aligned with the lamp holder, and the fixing sleeve 2001 of the connecting head 200 is aligned with the corresponding installation part on the lamp holder. By rotating the reflector cup 100, the threads 2002 on the inner wall of the fixing sleeve 2001 are screwed with the threads on the lamp holder, until the reflector cup 100 is installed stably. This installation process is simple and convenient, without the need for additional tools, and can ensure that the reflector cup 100 will not loosen.

[0030] Working process:

[0031] When the lamp is working, the light source emits strong light and generates a large amount of heat. The ceramic fiber of the inner heat insulation layer 100101 plays a role, effectively preventing heat from being transmitted to the inside of the reflector cup 100, reducing the influence of heat on the internal structure and optical performance of the reflector cup 100. Part of the heat passing through the inner heat insulation layer 100101 is further blocked when passing through the vacuum layer 100102, as there is almost no heat conduction medium in the vacuum environment.

[0032] The polyimide film of the outer heat insulation layer 100103 prevents heat from being emitted to other parts of the lamp, avoiding damage to the surrounding parts. The heat dissipation fins 100104 absorb the heat of the outer heat insulation layer 100103 and dissipate it. Air enters the air gap between the heat dissipation fins 100104 from the air inlet hole on the outside of the connecting sleeve 100105, absorbs the heat of the heat dissipation fins 100104 when flowing in the air gap, and then is discharged from the air outlet hole, forming natural convection and carrying away a large amount of heat.

[0033] The protrusion 1002 installed on the side wall of the inner heat insulation layer 100101 is coated with an aluminum film on the surface, which can reflect and focus light, improving the lighting effect of the lamp. During long-term use of the lamp, the heat-insulated reflector cup 100 always maintains good heat insulation and heat dissipation performance, ensuring stable operation of the lamp, and preventing the reflector cup 100 from deforming or performance degradation due to heat problems.
