Light-emitting diode (LED) lamp

Abstract

The invention provides a light-emitting diode (LED) lamp. The LED lamp comprises a lamp disk, a wire gathering disk which is arranged on the lamp disk, and a plurality of illumination modules, wherein a plurality of first wiring terminals which are connected with an external power supply are arranged in the wire gathering disk; each illumination module comprises module frameworks which are arranged in a plurality of openings correspondingly formed on the lamp disk, and a plurality of illumination units which are arranged on the module frameworks at intervals; each illumination unit comprises a hollow heat radiating piece, a circuit board which is arranged in the heat radiating piece and a light source module which is arranged on the heat radiating piece; the two ends of each illumination unit are provided with a joint piece respectively for sealing and fixed on each module framework; and the circuit boards of the illumination units supply power to the light source modules through second wiring terminals which are arranged on at least one joint piece and electrically connected with the first wiring terminals.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a modularized light-emitting diode lamp with high light efficiency. Background technique [0002] Traditional lighting sources consume a lot of energy. Semiconductor lighting using light emitting diodes (Light Emitting Diode, LED) is known for its high light efficiency, energy saving, longevity, environmental protection (mercury-free), fast start-up, strong light directionality, shock resistance and impact resistance. And other advantages, it has the potential to widely replace traditional lighting sources. [0003] However, the use of LEDs in lighting devices must be combined with a high-efficiency heat dissipation mechanism to reduce the temperature of the LEDs in order to take advantage of the above-mentioned advantages. Otherwise, the light efficiency and service life of the LED lamps will be greatly reduced, and the impact will make the use of the LED lamps. The energy-saving ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned LED lamps that use natural circulation to dissipate heat often reduce the luminous efficiency due to overheating of the LEDs and easily lead to light decay, which is not conducive to the life and stability of the lamps; and because the radiator is too heavy and the size of the lamps is not easy, it is difficult to increase the support and the burden of load; moreover, at the same time, multiple people need to use the lift to install the high-altitude lamps together, and even if there is only a small fault during use, the same equipment and manpower carrying tools need to be used to remove the whole lamp at high altitude. Replacing the whole lamp will not only greatly increase the maintenance cost of on-site disassembly and restoration of normal lighting, but also greatly reduce the efficiency; moreover, general lighting devices have low versatility. In order to meet different lighting applications and customer needs, different types are developed. The appearance and appearance of lamps must be redesigned and manufactured, resulting in waste of resources, increased costs and greatly reduced operating efficiency
