Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] refer to Figures 1 to 5 A range hood light, comprising:

[0033] Casing 1;

[0034] Lampshade 2 is fastened to housing 1, and lampshade 2 is provided with a first through hole 23;

[0035] The light strip 4 is located inside the housing 1 and is equipped with LED beads;

[0036] Spring clip 3 is located on the side of housing 1 away from lampshade 2; and

[0037] An infrared sensing device 100 is located inside the lamp cover 2; wherein, the infrared sensing device 100 includes an infrared sensor 5, which corresponds to the first through hole 23.

[0038] The range hood light is located on the range hood, with light strip 4 providing illumination. Infrared sensor 5 is used to detect the surface temperature of the cooktop, allowing the range hood to adjust its airflow (fan speed) based on the detected temperature. The cooktop can be a gas stove, induction cooker, ceramic cooktop, or other heating products.

[0039] Therefore, the range hood light integrates lighting and infrared temperature detection functions, improving functionality; moreover, the infrared sensor 100 is pre-installed in the range hood light, eliminating the need to find a separate location for assembly in the range hood, reducing the assembly process of the range hood, making assembly more convenient and efficient, and also helping to improve the aesthetics and overall appearance of the range hood.

[0040] refer to Figure 4 The probe end of the infrared sensor 5 is flush with the outer side of the light-emitting surface 20 of the lamp cover 2. Therefore, the probe end of the infrared sensor 5 does not protrude from the lamp cover 2, ensuring aesthetics.

[0041] The infrared sensor 100 can be located at one end or edge of the lampshade 2, that is, near the end or edge.

[0042] refer to Figure 2 and Figure 4 The infrared sensing device 100 also includes a circuit board 6, and the infrared sensor 5 is connected to the circuit board 6 to achieve a fixed connection and electrical connection between the two; the circuit board 6 is connected to the inner side of the light-emitting surface 20 of the lampshade 2.

[0043] The inner side of the light-emitting surface 20 of the lampshade 2 is provided with a plurality of first studs 22, each stud having a threaded hole. The circuit board 6 is provided with a second through hole 61 corresponding to the first studs 22; for example, four first studs 22 and four second through holes 61 are provided. The circuit board 6 is connected to the lampshade 2 by fasteners such as screws.

[0044] refer to Figure 6 The infrared sensor 5 includes a thermopile detection chip 51, a thermistor 52, and a wide-angle lens 54; infrared thermal radiation is irradiated onto the thermopile detection chip 51 after passing through the wide-angle lens 54.

[0045] The infrared sensor 5 is a thermopile structure. The thermopile detection chip 51 has structures such as a heated surface and a base surface, which can detect temperature. The thermistor 52 can also be used as a backup or auxiliary mode to detect temperature. For example, when the thermopile detection chip 51 is blocked by oil stains or dirt, the temperature can be detected by the thermistor 52.

[0046] Mode 1: The thermopile detection chip 51 is the primary sensor, and the thermistor 52 is the secondary sensor; Mode 2: When the thermopile detection chip 51 is blocked, the thermistor 52 performs temperature detection. Mode 1 takes precedence over Mode 2, thus enabling dual-mode operation, improving reliability and accuracy, and avoiding or reducing the possibility of temperature detection failure due to the thermopile detection chip 51 being blocked and unable to power on. Of course, in Mode 2, the thermistor 52 determines the stove surface temperature based on the voltage output characteristic table.

[0047] refer to Figure 6 The infrared thermopile sensor also includes a substrate 53 and a bracket 55. The thermopile detection chip 51 and the thermistor 52 are both connected to the substrate 53, and the thermistor 52 is located on one side of the thermopile detection chip 51.

[0048] The bracket 55 covers the thermopile detection chip 51 and the thermistor 52. A wide-angle lens 54 is provided at the end of the bracket 55 away from the substrate 53. The bracket 55 can be connected to the substrate 53 by soldering. The substrate 53 is soldered to the circuit board 6 through pins 56.

[0049] The wide-angle lens 54 is beneficial for improving the detection range. The wide-angle lens 54 can be a 120-degree wide-angle 120 structure.

[0050] refer to Figure 2 The lampshade 2 has a protruding buckle 21 on its edge, and the housing 1 has a buckle groove 11 that matches the protruding buckle 21. Thus, the lampshade 2 is fastened to the housing 1, making it easy to install and remove.

[0051] refer to Figure 2The housing 1 has a limiting groove 12 on the side away from the lampshade 2. The limiting groove 12 cooperates with the spring clip 3, which can accommodate part of the spring clip 3. The spring clip 3 is roughly bow-shaped, and the range hood light is snapped or clamped onto the range hood through the spring clip 3. The setting of the limiting groove 12 improves the accuracy and assembly convenience of the spring clip 3. The spring clip 3 is assembled to the housing 1 by screws or the like.

[0052] The lampshade 2 is made of a light-transmitting material, such as PMMA, PC, PS, or other plastics, while the housing 1 can be made of plastic. The light strip 4 can be assembled into the interior of the housing 1 using fasteners such as screws.

[0053] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
