Traditional lighting comparison display cases are mostly transparent glass cabinets, which are easily affected by internal and external temperature and lighting factors. Furthermore, visual observation of the corresponding performance parameters only reveals differences in brightness and cannot accurately compare other performance aspects of the lighting fixtures. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a convenient observation and real-time display-enabled lamp comparison display box. The purpose of this utility model can be achieved through the following technical solution: A lamp comparison display box, including a box body and lamps, characterized in that two horizontally arranged placement platforms are provided inside the box body, dividing the box body into an upper layer, a middle layer and a lower layer. The upper layer of the box body is provided with two sets of smart meters for real-time monitoring of the electrical parameters of the lamps, a thermometer for measuring the temperature of the lamp heat sink, and an illuminance meter for measuring the luminous flux of the lamps. The lamps are placed in the middle layer of the box body, and a heat sink is provided on the lamps. A heat insulation layer, which is a heat insulation rubber pad, is provided between the heat sink and the placement platform of the middle layer of the box body. A temperature sensor is provided between the heat insulation layer and the heat sink. A black velvet cloth is provided on the inner wall of the lower layer of the box body for light absorption. The lower layer of the box is provided with a lower partition, which, together with the placement plate, divides the lower layer of the box into two observation chambers. An observation window connected to the box is provided on the outer side of the observation chamber. The radiator is equipped with a lifting ring for the power supply wires to pass through, and a PG connector is provided below the upper placement plate of the housing for the power supply wires to pass through and be fixed.

[0004] In the aforementioned lamp comparison display box, an illuminance sensor is provided at the bottom of the observation chamber, which is connected to the corresponding lamp and used to measure the luminous flux of the lamp. The illuminance sensor is connected to the illuminance meter circuit.

[0005] In the aforementioned lamp comparison display case, the temperature gauge is connected to the temperature sensor circuit.

[0006] In the aforementioned lamp comparison display case, a control switch corresponding to each of the two lamps is provided on the top of the case. This control switch is used to control the opening and closing of the circuit.

[0007] In the aforementioned lighting comparison display case, the observation window is a semi-transparent acrylic glass plate, which is used to reduce interference from external light sources.

[0008] In the aforementioned lamp comparison display case, the bottom of the case is provided with several roller assemblies for moving the case.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2As shown, the comparison display case for this lamp 2 includes a case body 1 and a lamp 2. The case body 1 has two horizontally arranged placement platforms, dividing the interior of the case body 1 into an upper layer, a middle layer, and a lower layer. The upper layer of the case body 1 is equipped with two sets of smart meters 12 for real-time monitoring of the electrical parameters of the lamp 2, a thermometer 15 for measuring the temperature of the heat sink 9 of the lamp 2, and an illuminance meter 14 for measuring the luminous flux of the lamp 2. The lamp 2 is placed in the middle layer of the case body 1, and the heat sink 9 is installed on the lamp 2. A heat insulation layer 4 is provided between the heat sink 9 and the placement plate 3 in the middle layer of the case body 1. The heat insulation layer 4 is a heat insulation rubber pad. A temperature sensor 13 is provided between the heat insulation layer 4 and the heat sink 9. A black velvet cloth 7 is provided on the inner wall of the lower layer of the case body 1. The black velvet cloth 7 is used for light absorption.

[0016] The lower layer of the box 1 is provided with a lower partition 5, which, together with the placement plate 3, divides the lower layer of the box 1 into two observation chambers 6. An observation window 8 connected to the box 1 is provided on the outside of the observation chamber 6. A hanging ring 10 is provided on the radiator 9, which is used for the power supply wire of the lamp 2 to pass through. A PG connector 11 is provided below the upper placement plate 3 of the housing 1 for the power supply wire to pass through and be fixed.

[0017] When the lamp 2 is powered on during use, the lamp 2 starts to work. The illuminance sensor 16 receives the illuminance emitted by the lamp 2 and its luminous flux and displays the real-time luminous flux value on the illuminance meter. The heat insulation layer 4 avoids direct contact between the heat sink 9 and the housing 1, preventing the heat conduction of the metal housing 1 from affecting the accuracy of the temperature sensor 13 in measuring the temperature of the heat sink 9. The observation chamber 6 is lined with black velvet cloth 7, which makes the observation chamber 6 light-absorbing, avoiding mutual interference between contrasting brightness and making it more conducive to observation.

[0018] To elaborate further, the radiator 9 is provided with a hanging ring 10, which is used for the power supply wire of the lamp 2 to pass through. Below the upper placement plate 3 of the housing 1, there is a PG connector 11 for the power supply wire to pass through and be fixed.

[0019] To elaborate further, the smart meter 12 monitors the output power, usage power, and electrical parameters in real time, ensuring comparison with the lamp 2 under the same environment.

[0020] To elaborate further, the top of the housing 1 is equipped with control switches 17 corresponding to the two lamps 2 respectively. These control switches 17 are used to control the opening and closing of the circuit.

[0021] To elaborate further, the thermometer 15 is connected to the temperature sensor 13 in a circuit.

[0022] To elaborate further, observation window 8 is a semi-transparent acrylic glass plate, which is used to reduce interference from external light sources.

[0023] To elaborate further, the bottom of the housing 1 is provided with several roller assemblies 18 for moving the housing 1.

[0024] To elaborate further, pull rods 19 for pushing the box 1 are provided on both sides of the top of the box 1.

[0025] To elaborate further, a five-hole socket 20 is also installed at the rear of the upper layer of the cabinet 1.
