摘要： A luminaire comprising a housing having thermally separate compartments for an electronics portion and a lighting portion. These thermally separate compartments can provide thermal isolation between the electronics portion and the lighting portion. The lighting portion comprises a plurality of light-emitting elements and further includes an optical device comprising two linear diffuser elements and can be used to further improve the light emission characteristics of the light-emitting elements thereby providing a directly viewable luminaire wherein the illumination produced by point light sources appears uniform along the length of the luminaire. A power supply for supply of energy to the light-emitting elements and a controller for controlling application of energy from a power source to the light-emitting elements is provided in the electronics portion and can be thermally separated within the electronics portion.

The containment casing (2) is provided with a base body (3) and with a closure body (4) fixed to the base body (3), delimiting a housing volume therewith and having a transparent portion (5) susceptible of being traversed by the light. The support body (6) is placed inside the housing volume of the containment casing (2), is extended along a vertical extension direction (X) between a base portion (7) and an opposite top portion (8) and is provided with a lateral surface (9) extended around the extension direction (X) between the base portion (7) and the top portion (8). The light sources (10) are mounted on the lateral surface (9) of the support body (6), are placed around the extension direction (X) and are each provided with a first optical emission axis (Y) thereof which intercepts the transparent portion (5) of the closure body (4). In addition, the support body (6) is extended, at least partially along the extension direction (X), with shape tapered from the base portion (7) towards the top portion (8), and the lateral surface (9) is tilted with respect to the extension direction (X) and supports the first light sources (10) with their first optical emission axis (Y) oriented partially upward.

摘要： Provided in the present invention is an explosion-proof lighting device (21), comprising: a device body (21) for accommodating the explosion-proof lighting device, the device body comprising a mounting portion located in the middle portion thereof and a first heat dissipation portion and a second heat dissipation portion that extend from the bottom of the mounting portion to two sides; a plurality of light emitting diodes (LEDs) for emitting light to illuminate; an electrical drive module for powering the light emitting diodes; and a seal cover detachably connected to the device body from the bottom thereof. The present invention allows for reliable dissipation of heat generated by the light emitting diodes to the ambient environment without separately providing a heat dissipation device, avoids the direct adverse effects of heat generated by the light emitting diodes on the electrical drive module while achieving compactness and low height of the explosion-proof lighting device, and significantly reduces the number of parts and costs for production, assembly and manufacturing of the explosion-proof lighting device.
