An aiding device for lamp heat dissipation facilitates the heat dissipation of a lamp. A portion of the lamp has an engaging portion. The aiding device includes an engaging groove, and the engaging groove of the aiding device is adapted to be engaged with the engaging portion of the lamp, so that the aiding device is assembled on the lamp. Accordingly, the temperatures of the power module, the electronic components, or the light emitting components can be reduced through heat dissipation, thereby extending the lifetime of the lamp.

A wall grazer apparatus is provided. The wall grazer apparatus has a heat sink platform, a light source, a lens, a driver and a main housing. The heat sink platform has a main portion and a tilt portion. The light source is mounted on the tilt portion. The lens is disposed above the light source to convert an original light emitted from the light source to an output light. The driver converts an external power to a driving current. The driving current is supplied to the light source. The main housing disposes the heat sink platform, the light source, the lens and the driver. When the main housing is fixed to a first surface, the output light is projected on a second surface for forming a visual effect.

A retrofit switch apparatus is designed for attaching to a mechanical switch. The mechanical switch has a manual switch for performing an operation of a connected target device. The retrofit switch apparatus includes an assembly box, a wireless module, a switch unit, and a control unit. The assembly box covers the mechanical switch. The wireless module is used for receiving an external command. The switch unit has a driving structure. The driving structure is disposed in the assembly box for engaging with the mechanical switch for moving the mechanical switch to perform the operation according to the external command. The control unit has an operating unit and a trigger unit connected to the operating unit. A portion of the operating unit is exposed outside a surface of the assembly box for a user to operate to directly trigger the mechanical switch.

A heat sink 41 is provided on a lower edge side, for example, of a display panel 21 with a heat radiation surface being on a display surface side of the display panel 21. A heat source, such as a light source 22, which generates heat owing to display operation using the display panel 21 is mounted on a mounting face opposite to the heat radiation surface. A cover 31 that covers the heat sink 41 is provided on the display surface side of the display panel 21. Air holes 311 and 312 are formed on a top face 31t and a bottom face 31b, respectively, of the cover 31. Air taken in through the air holes 312 on the bottom face 31b of the cover 31 cools the heat sink 41, and the air heated by the heat of the heat sink 41 is dissipated outside through the air holes 311 on the top face 31t. Heat generated inside the display device is efficiently dissipated with a small ventilation resistance without generation of noise. Since heat is dissipated on the display surface side, discoloration of wall paper on a mounting face and the like is prevented or reduced.

An innovative light fixture for use with acoustical shells is disclosed. The fixture incorporates a dome gimbal to allow rotation front-to-back and left-right around a horizontal axis and a third axis of rotation around a vertical axis. The dome configuration allows for a low profile and toolless adjustment allows stage side aiming by hand.
