This creation is about a luminaire structure, especially a luminaire structure with a heat dissipation effect.

In the prior art illuminating device, such as an incandescent bulb and a halogen bulb, the wick is heated to illuminate or the fluorescent tube is used to illuminate the gas molecules in the tube, and the high temperature is accompanied by the operation. In particular, a light-emitting device using a light-emitting diode (LED) as a light source, although it is generally believed that the light-emitting diode has high luminous efficiency, the high temperature generated by the light-emitting diode under long-term operation will greatly reduce the luminous efficiency. Therefore, various lamp structures carrying light-emitting devices require good heat dissipation capability to prevent the light-emitting device from reducing efficiency or reducing life due to high temperatures.

In the conventional luminaires, as disclosed in Chinese Patent No. M317543, heat-dissipating fins are added to the luminaire, and the heat generated by the illuminating device in the luminaire is transmitted to the outside through the heat-dissipating fins. To dissipate the heat generated by the illuminating device. However, conventional lamps are only transmitted through conduction, and there is still a problem that heat dissipation cannot be quickly and effectively performed.

In view of this, it is an extremely desirable goal in the industry to provide a luminaire structure to improve the above-mentioned deficiencies.

One of the aims of the present invention is to provide a lamp structure that not only dissipates heat to the light-emitting module in a conductive manner, but also has a hole for convection of air, thereby improving the heat dissipation efficiency of the lamp structure.

To achieve the above objective, the lamp structure comprises: a heat sink, a lamp panel, a lighting module, a power board, a lamp body and a conductive portion. The heat sink has a first end, a second end and a first side. The first end has a first opening and the second end has a second opening. The lamp disc portion has a bearing surface and a second side surface. The lamp disc portion is disposed in the first opening of the first end portion, and the second side surface is in contact with the first side surface of the heat dissipating body. The illuminating module is disposed on the bearing surface of the lamp disc portion and has a plurality of illuminating diodes. The power board is electrically connected to the light emitting module. The body of the lamp body has a body, a third end portion and an accommodating space. The body of the lamp body portion is disposed in the heat dissipating body via the second opening, so that the third end portion is located outside the heat dissipating body and is coupled to the heat dissipating body. The second ends are connected. The conductive portion is in contact with the third end of the lamp body portion. Wherein at least one of the lamp disc portion and the lamp body portion has a plurality of heat dissipation holes. By the contact between the lamp panel and the heat sink, the luminaire structure of the present invention can conduct the heat energy of the illuminating module to the outside.
