Description

Technical Field

[0001] The utility model relates to the technical field of lamp structures, in particular to a sealing structure and a chip induction lamp. Background Art

[0002] Currently, the sensor chips used in many chip sensor lamp products on the market do not have good waterproof performance.

[0003] In actual use, especially in outdoor or humid environments such as bathrooms, by swimming pools, or in rainy areas, the chips of these non-waterproof chip sensor lights are easily corroded by moisture, causing short circuits, corrosion, or other damage to the chip's internal circuits. This not only shortens the lamp's service life and increases maintenance costs, but also poses a safety hazard.

[0004] To improve product reliability and durability, some manufacturers currently coat sensor chips with conformal coating (moisture-proof, dust-proof, and corrosion-resistant) to provide a certain degree of protection. Although this method can alleviate the problem to a certain extent, it still has limitations. The coating thickness is difficult to control uniformly. Too thick will affect the heat dissipation effect, while too thin will have limited protective effect. In addition, when the chip is exposed to harsh environments for a long time, the conformal coating may gradually age and fail. Utility Model Content

The sensor chip 112 is attached to the side of the sealing seat 113 that directly contacts the thermally conductive substrate 110 to conduct away the heat generated by the sensor chip 112.

[0038] According to the above scheme, it can be understood that this embodiment installs the sealing seat 113 for loading the sensing chip 112 on the thermally conductive substrate 110, and seals the sealing seat 113 through the thermally conductive substrate 110, thereby realizing the installation of the sensing chip 112 without the need for a chip box structure, and realizes sealing by using the sealing seat 113 to load the sensing chip 112 and install it into the thermally conductive substrate 110, and designs the sensing chip 112 to be attached to the side of the sealing seat 113 that directly contacts the thermally conductive substrate 110, thereby realizing the rapid transfer of the heat of the sensing chip 112 through the sealing seat 113 to the thermally conductive substrate 110, and the rapid heat dissipation through the thermally conductive substrate 110, so that the temperature of the chip is maintained within a certain range under continuous working conditions, thereby improving the performance stability of the chip and ensuring the normal use of the lamp.

In this embodiment, a recess is designed on one side of the thermal conductive substrate 110 facing the irradiation direction of the light-emitting plate 111, so that the recess forms a sealing chamber 114 integrally formed with the thermal conductive substrate 110. The sealing seat 113 on which the sensing chip 112 is installed is installed into the sealing chamber 114, thereby achieving the installation and sealing of the sensing chip 112.
