Modular LED lamp structure with replaceable modules
View Patent ↗A LED lamp structure includes a LED emitting module and a radiator module. The radiator module includes a holder with an elastic slice to connect electrically to a driver unit for supplying power. The driver unit may be disposed in the radiator module or within the LED emitting module. Therefore, the structure of the LED lamp is simplified. The modules can be replaced when they break down, without having to discard the whole set of LED lamp, thus eliminating the unnecessary waste, in achieving cost-effectiveness and environment protection.
1. A LED lamp structure, comprising:
a radiator module, including:
a dissipating base, has a plurality of fins thereon;
a holder, mounted on the dissipating base; and
a driver unit, electrically connected to the holder; and
a light emitting module, disposed on the radiator module and connected to the holder for electrically connection to the driver unit; the light emitting module comprising:
a body;
a substrate, supported by the body and having a plurality of LEDs disposed thereon; and
a lamp cover, disposed on the body and covering the substrate to protect the LEDs
wherein the body of the light emitting module includes at least one fixing pillar to electrically and physically connect to the holder of the radiator module;
wherein the holder of the radiator module includes a slot and a clamping edge extended from the slot, and the fixing pillar includes a neck section and a connected head section with an outer diameter of the head section greater than a diameter of the neck section;
wherein a diameter of the slot being greater than a width of the clamping edge and the diameter of the slot being large enough for the head section of the fixing pillar to go through, and the clamping edge having a second internal diameter which is too small to allow the head section of the fixing pillar to go through, so that the fixing pillar is inserted into the holder through the slot and slid laterally to the clamping edge for holding the neck section.
2. The LED lamp structure of claim 1 , wherein the driver unit is disposed in the dissipating base.
3. The LED lamp structure of claim 1 , wherein the holder includes an elastic slice connected to the driver unit and disposed adjacent to the slot, when the neck section of the fixing pillar is held by the clamping edge, the fixing pillar is connected electrically to the driver unit through the elastic slice.
4. The LED lamp structure of claim 1 , wherein the fixing pillar is electrically connected to the LEDs by at least one electrical lead.
5. The LED lamp structure of claim 1 , wherein lamp cover includes a clip to fix on a notch of the body.
6. The LED lamp structure of claim 1 , further comprising a supporting ring to support the radiator module.
7. The LED lamp structure of claim 6 , wherein supporting ring includes an elastic fastener.
