Lamp with air channel
First Claim
1. A lamp, comprising:
- a housing having a first compartment, and a first opening on an end thereof and a first protrusion extending outward from a periphery of the first opening;
an inner shell adapted to be received in the first compartment and having a second compartment and a second opening on an end thereof, and a second protrusion extending outward from a periphery of the second opening, wherein the first protrusion abuts with the second protrusion such that the first opening is closed by the second protrusion, a separation member abutting against the housing and the inner shell so as to form an air channel between the housing and the inner shell in the first compartment, wherein the separation member is in form of a labyrinth protrusion adapted to separate the air channel into a first air channel and a second air channel, the inner shell further comprises a through-hole allowing the first compartment to communicate with the second compartment;
a fan located adjacent to the through-hole and having two air-flowing sides for drawing air in and out of the lamp such that the air is allowed to pass through the through-hole;
a heat sink having a bottom plate with one face facing the fan; and
a lighting module adapted to be coupled to another face of the bottom plate.

Abstract
A lamp comprises a housing, an inner shell, a fan, a heat sink and a lighting module. The housing has a first compartment and a first opening on an end thereof. The inner shell is adapted to be received in the first compartment and has a second compartment and a second opening on an end thereof, wherein the second opening is aligned with the first opening. An air channel is formed between the housing and the inner shell in the first compartment. The inner shell further comprises a through-hole allowing the first compartment to communicate with the second compartment. The fan is located adjacent to the through-hole and has two air-flowing sides for drawing air in and out of the lamp. The heat sink has a bottom plate with one face facing the fan. The lighting module is adapted to be coupled to another face of the bottom plate.
