Examples disclosed herein relate to a method and apparatus for inspecting lamp dimensions. The method includes determining an actual measurement of a lamp. The lamp is configured to heat a substrate in a substrate processing apparatus. A window is generated, the window having a width and a height. The window is based upon a target measurement of the lamp. The method further includes generating a deviation based upon a difference between an image of the actual measurement and the window. The deviation is compared to a first threshold. The lamp is rejected if the deviation is outside the first threshold.

A downlight apparatus includes a light source, a light holder, a driver box, a fixing bracket and two torsion springs. The light holder is used for placing the light source. The light holder has a first side defining a light opening. The driver box is placed on a second side of the light holder. The driver box contains a driver for converting an external power to a driving current supplied to the light source to emit a light from the light opening. The fixing bracket is coupled to the light holder for fixing to an installation cavity. The fixing bracket has a bottom plate and two connector plate. The bottom plate is fixed to the second side of the light holder. The two connector plates are disposed vertically to the bottom plate. Each connector plate has two side units. Each torsion spring has an elastic center and two arms.

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

A backlight source module and a display device are provided. The backlight source module includes a back plate structure and a rubber member. The back plate structure includes a bottom plate, and a first side plate and a second side plate respectively connected with the bottom plate, and the first side plate and the second side plate oppose each other. A light-emitting portion, a light-guiding component and the rubber member are sequentially disposed on the bottom plate along a first direction pointing from the first side plate to the second side plate. The rubber member is only disposed at the second side plate.

A downlight apparatus includes a main housing, and a light module and an optical module both arranged inside the main housing. The downlight apparatus also includes a fire resistant enclosure arranged at a rearward side of the main housing. The fire resistant enclosure is detachably coupled to the main housing. The main housing and the fire resistant enclosure form a compartment. A driving module having a communication board is arranged inside the compartment.

The present application discloses a lamp body and a bulb lamp, the lamp body includes a lampshade and a light source assembly, which is integrated on the lampshade. The light source assembly is integrated on the lampshade, a distance between the light source assembly and the external environment is shorten, and the thermal performance is improved. The lampshade includes a mounting window, and the light source assembly is mounted in the mounting window, so that heat of the light source assembly can be directly dissipated to the external environment. The light source assembly includes a light source a transparent light source substrate, a surface of the light source substrate facing an inner cavity of the lampshade is a mounting surface, and the light source is mounted on the mounting surface. The bulb lamp includes a lamp holder and the abovementioned lamp body, the lampshade is connected with the lamp holder.
