  • Patent number: 11898729
    Abstract: A lighting apparatus includes a driver module, a light source, a main housing and an optical plate. The driver module converts an external power to a driving current. The light source includes multiple LED chips. The light source is coupled to to the drive module to emit a light. The main housing is used for disposing the driver module and the light source. The optical plate is detachably inserted into a sliding track of the main housing via a lateral opening of the main housing so that the optical plate is replaceable. The optical plate changes a light direction of the light emitted by the light source to a light opening. A first surface of the light opening is substantially perpendicular to a second surface of the lateral opening.
    Type: Grant

  • Patent number: 11747009
    Abstract: A lighting apparatus includes a light head, a driver box, multiple separating columns and a light source module. The light head has an Edison cap and a head body. The head body has a rotatable connector. The driver box has a first side and a second side for containing a driver circuit. The first side of the driver box has a fixing unit corresponding to the rotatable connector of the head body to selectively attach or detach the light head from the driver box by rotating the rotatable connector with respect to the fixing unit. The light source plate has a light source plate mounted with LED modules. The light source plate is fixed to the driver box with the multiple separating columns. The separating columns form an air gap between the driver box and the light source for heat dissipation.
