Abstract
An illumination device includes a heat dissipation assembly at least partially disposed in a first accommodation space of a housing. The housing is provided with an air inlet for an airflow to enter the first accommodation space and an air outlet for the airflow passing through the airflow channel to flow out of the first accommodation space. The airflow channels are disposed along an up and down direction, and the air outlet is at least partially provided above the airflow channels.
Claims20
An illumination device, comprising:
- a housing having a first accommodation space;
- a power supply coupling portion disposed on the housing;
- a panel assembly comprising light emitters and supported by the housing;
- a direct current power supply powering the light emitters coupled to the power supply coupling portion;
- and
- a heat dissipation assembly at least partially disposed in the first accommodation space and comprising airflow channels at least partially disposed along an up and down direction for an airflow to flow through;
- wherein the housing is provided with an air inlet for the airflow to enter the first accommodation space and an air outlet for the airflow passing through the airflow channels to flow out of the first accommodation space, and the air outlet is at least partially provided above the airflow channels.
