An LED luminaire including an outer LED support member having a plurality of LED arrays positioned on a lower side thereof, an LED driver housing centrally located within an interior of the outer LED support member, wherein the outer LED support member is secured to the LED driver housing with a plurality of attachment arms that extend from inner surface of the outer LED support member to the LED driver housing, such that are open spaces between the plurality of attachment arms and between the inner surface of outer LED support member and the LED driver housing, and a plurality of heat dissipating fins positioned on an upper surface of the outer LED support member extending towards the LED driver housing.

Provided in the present invention is an explosion-proof lighting device, comprising: a device body 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 additionally 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 reduced 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.

A downlight apparatus includes a light source, a light housing and a stop unit. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The driver box has a wall with an installation escape. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The stop unit is fixed to the installation escape. The stop unit has a switch holder and a wire holder. A manual switch is placed in the switch holder and an enlarged wire head of an power wire is placed in the wire holder. An operation part of the manual switch is exposed outside the driver box. The manual switch is connected to the driver for adjusting a setting of the driver.

A luminaire includes a core made up of a first material and an LED lighting arrangement mounted to the core. The luminaire further includes a housing made up of a second material. The second material is different from the first material. The housing including a recess in which the core is received. The housing further includes a finned part.

An LED light fixture for a hazardous location includes an axially elongated enclosure fabricated from a glassfiber reinforced plastic material, at least one axially elongated linear light emitting diode (LED) module mounted in the enclosure, and an LED driver module mounted in the housing that operates the at least one linear light emitting diode. The LED driver module and the at least one axially elongated linear LED module are operable within a target peak temperature limit for the hazardous location, without utilizing heat sinks to dissipate heat in order to provide acceptable thermal management.
