Abstract

An optical module includes a light plate and a heat dissipation structure. The heat dissipation structure includes a first substrate connected to the light plate, and a second substrate disposed under the first substrate. The first and second substrates are made of aluminum or an aluminum alloy material. A first anodized aluminum layer is disposed on a side of the first substrate adjacent to the second substrate. A second anodized aluminum layer is disposed on a side of the second substrate adjacent to the first substrate. A gap is defined between the first and second anodized aluminum layers, and there are disposed cooling droplets in the gap. When each light-emitting element is at a first heating value, the respective cooling droplet moves to a position under the light-emitting element. When each light-emitting element is at a second heating value, the respective coolant drop leaves from under the light-emitting element.

Dependent claims

An optical module, comprising a light plate on which a plurality of light-emitting elements are arranged in an array, and further comprising a heat dissipation structure arranged on a side of the light plate facing away from the plurality of light-emitting elements;

wherein the heat dissipation structure comprises a first substrate and a second substrate, the first substrate being arranged above the second substrate and connected to the light plate;
wherein the first substrate and the second substrate are each made of aluminum or an aluminum alloy;
wherein there is disposed a first anodized aluminum layer on a side of the first substrate adjacent to the second substrate, and there is disposed a second anodized aluminum layer on a side of the second substrate adjacent to the first substrate;
and there is defined a gap between the first anodized aluminum layer and the second anodized aluminum layer, and there is disposed a plurality of cooling droplets in the gap;
wherein in response to each of the plurality of light-emitting elements being at a first heating value, the respective cooling droplet is operative to move to a position under the light-emitting element;
and in response to each of the plurality of light-emitting elements being at a second heating value, the respective cooling droplet is operative to leave from under the light-emitting element.
