Engineering Contradiction Analysis
1Device complexity
If power supply circuitry and light source are packaged together in the same cavity, then device complexity is reduced, but heat management and electrical safety are compromised
Solution Approach 1:
The cavity is divided into a first cavity for the power supply circuit board and a second cavity for the light source module, with a partition wall separating them. This segmentation allows independent management of electrical components and light-emitting components, improving electrical safety and heat management while maintaining integrated packaging.
2Device complexity
If power supply circuitry and light source are packaged together in the same cavity, then device complexity is reduced, but heat management deteriorates
Solution Approach 1:
The cavity is divided into a first cavity for the power supply circuit board and a second cavity for the light source module, with a partition wall separating them. This segmentation allows independent thermal management of heat-generating components, preventing heat accumulation and improving overall heat dissipation efficiency.
3Reliability

AI summary
A housing has a sidewall that surrounds an interior cavity that has an open rear end and an open front end, and is divided by a partition into a top cavity and a bottom cavity. The top cavity extends to the open rear end, the bottom cavity extends to the open front end. A power supply circuit board is inside the top cavity, while a light source is inside the bottom cavity and emits light through the open front end to illuminate a room. First wires pass through an opening in the partition, and are coupled to the power supply circuit board at one end and to the light source at another end, to deliver power to the light source. A lid or cover covers the open rear end enclosing the top cavity, and is secured to the housing. Other embodiments are also described and claimed.
