Light-emitting diode lamp

The invention relates to a lighting device, in particular to a light-emitting diode lamp.

As an emerging third-generation light source, the light-emitting diode has been widely regarded by the market for its long working life, energy saving and environmental protection. Moreover, the current module consisting of a light-emitting diode can generate a high-power, high-brightness light source, which can completely replace the conventional incandescent lamp to achieve indoor and outdoor lighting, and will also widely and revolutionarily replace the traditional incandescent lamp. The light source has become the main light source in line with the theme of energy conservation and environmental protection. As the related product technology of the light-emitting diodes continues to mature, the light-emitting diode lamps will be more and more widely used as a new environmentally-friendly and energy-saving next-generation light source.

A conventional light-emitting diode lamp usually includes a light-emitting diode module, a heat sink that is in thermal contact with the light-emitting diode module, a power module electrically connected to the light-emitting diode module, and a housing. seat. The light emitting diode module, the heat sink and the power module are installed in the receiving seat. However, since the power of the LED module is relatively large, the heat generated by the LED module is used to convert the AC power into DC power to supply the power required for the operation of the LED module. Some heat is also generated, and the power module occupies a large volume in the accommodating seat, and the space of the accommodating seat is limited, so that a large amount of heat generated by the illuminating diode module and the power module is accumulated in the accommodating seat. It is not easy to discharge inside, and causes the entire luminaire to work in an overheated state and affect its life.

In view of this, it is necessary to provide a light-emitting diode lamp with better heat dissipation performance.

A light-emitting diode lamp includes a light stand, a power module and at least one illuminator mounted on the lamp stand, the illuminator comprising a plurality of light-emitting diode modules, the power module and the illuminating The body phase is independently disposed, and is connected to the light emitting diode module in the illuminating body by wires to supply electric energy required for the operation of the illuminating diode module.

At least one illuminant of the luminaire of the present invention uses only one power module, and the power module is independently arranged with the illuminator, so that the design not only saves space, but also effectively solves the generation of the illuminating diode module and the power module. The problem of heat accumulation is not easy to discharge.
