Abstract
A lighting device includes a light housing; a light source disposed at least partially in the light housing; a battery pack with a height dimension H1 defined; and a battery pack receiving portion formed on or connected to the light housing. The light housing includes a first state with a height dimension H2 and a second state with a height dimension H3 along a height direction of the light housing, the height dimension H2 in the first state is less than the height dimension H3 in the second state, and the height dimension H2 in the first state is less than or equal to the height dimension H1 of the battery pack.
Claims20
A lighting device, comprising:
- a light housing;
- a light source disposed at least partially in the light housing;
- a battery pack having a height dimension H1;
- and
- a battery pack receiving portion formed on or connected to the light housing;
