LED lamp

Abstract

The invention provides an LED lamp, which comprises a lamp panel, a plurality of first wiring terminals and a plurality of lighting modules, wherein the lamp panel is provided with a plurality of openings, and each lighting module is arranged on each opening; the first wiring terminals are respectively arranged on at least one inner side wall of each opening at intervals and electrically connected with an external power supply; each lighting module comprises a plurality of lighting units, wherein each lighting unit comprises a hollow heat dissipating member, a circuit board and a light source module arranged on the heat dissipating member; each of the two ends of each lighting unit is respectively provided with a joint member and the joint members are arranged on the inner side walls of the openings at intervals in a sealing way; and the circuit board of each lighting unit is used for supplying power to the light source modules through second wiring terminals which are arranged on at least one joint member 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 heat dissipation efficiency. Background technique [0002] Traditional lighting sources consume a lot of energy, while Light Emitting Diode (LED) has the advantages of high light efficiency, energy saving, long life, environmental protection (mercury-free), fast start-up, strong light directionality, shock resistance and impact resistance, etc. It has the potential to widely replace traditional lighting sources. [0003] However, the use of LEDs in lighting devices must cooperate with a high-efficiency heat dissipation mechanism to reduce the temperature of the LEDs in order to exert the above-mentioned advantages. Otherwise, the luminous efficiency and service life of the LED will be greatly reduced, and the impact will make the lighting device using the LED less effective in energy saving, and directly impact the reliability of th...

AI Technical Summary

Problems solved by technology

However, the above-mentioned lighting devices that use natural circulation to dissipate heat generally reduce the light efficiency and easily lead to light decay due to overheating of the LEDs, which is not conducive to the life and stability of the lamps.

And because of the overweight of the radiator and the small size of the lamp, it is not easy to increase the burden of support and load

It is also because multiple people need to work together to install the high-altitude lamps through the elevator, and even if there is a minor fault during use, the same equipment and manpower carrying tools need to be used to remove the entire lamp at high altitude and then replace the entire lamp. In addition to greatly increasing the maintenance cost of on-site disassembly and restoration of normal lighting, the efficiency is also greatly reduced

Furthermore, the versatility of general lighting devices is low. In order to meet different lighting applications and customer needs, lamps with different types and appearances must be redesigned and manufactured, resulting in waste of resources, increased costs and greatly reduced operating efficiency.
