Abstract
The utility model relates to a modularized high-power LED lamp which is characterized by comprising a plurality of LED lamp modules, bolts and a support; each LED lamp module comprises a radiator (1) with an installation hole, a plurality of LEDs (2) and a plurality of protective covers (3); the corresponding LED and the protective cover are sealed by sealant; the bolts (4) are used for serially connecting all the LED lamp modules; two adjacent radiators are separated by a sleeve (5) which is sleeved on the bolt and are serially connected into an integral modularized high-power LED lamp and fixed on the support. Compared with the prior art, the modularized high-power LED lamp has the advantages that the LED on each module is provided with the independent radiator and an independent power supply; consequently, the junction temperature of and the borne current of each LED can be kept consistent; and simultaneously, because a ventilation gap between each independent module makes the radiating effect better so that the high-power LED lamp has longer service life and lower brightness attenuation.
Description
Technical field
The utility model relates to a kind of lighting, and particularly a kind of is the modular high-power LED lighting of light source with a plurality of great power LEDs.
Background technology
Existing high-power LED lamp usually is made up of the heat-dissipating casing of integral body, the lamp plate that plurality of LEDs is housed, transparent lower cover, power supply etc., and the connecting mode of plurality of LEDs normally connects-mode that parallel connection has concurrently.Under such structure, all LED are installed on the module radiator, heat is concentrated and is difficult to shed, and the low phenomenon of fringe region the zone line height can appear and in the temperature of monoblock radiator simultaneously, and this will cause the junction temperature of chip of each area L ED inconsistent and influence service life of light fixture.Simultaneously, the connecting mode of plurality of LEDs is the mode that series connection-parallel connection has concurrently, because the junction voltage electrical quantity of every LEDs is also not quite identical, this can cause the electric current of every LEDs to distribute unbalanced and make partial L ED bear higher power, bears the service life that more high-power LED influences faster decay light fixture.
Summary of the invention
The purpose of this utility model is to provide a kind of modular high-power LED light fixture, adopts modularized radiator, makes each LED heat radiation evenly, guarantees each LED junction voltage unanimity, improves the service life of LED light fixture.
A kind of modular high-power LED light fixture, it is characterized in that: by several LED lamp modules, bolt, be configured to, each LED lamp module contains a radiator 1 that has installing hole, a plurality of LED2, a plurality of protective covers 3, adopt the fluid sealant sealing-in between corresponding LED and the protective cover, adopt bolt 4 that each LED lamp module is concatenated into one, isolate with the sleeve pipe 5 that is sleeved on the bolt 4 between two adjacent radiators 1, be concatenated into holistic modular high-power LED light fixture, and be fixed on the support.
With prior art relatively, the utility model has the advantages that: the LED on each module has individual heat sinks and power supply independently, the junction temperature of every like this LEDs and the electric current that bears can be consistent, simultaneously, owing to have ventilation gap to make heat radiation more good between each standalone module, thereby make high-power LED lamp have longer working life and littler brightness decay.

The specific embodiment
Embodiment 1:
A kind of modular high-power LED light fixture, it is characterized in that: by several LED lamp modules, bolt, be configured to, each LED lamp module contains a radiator 1 that has installing hole, the white light LEDs 2 of 20 3W, a plurality of protective covers 3, adopt the fluid sealant sealing-in between corresponding LED and the protective cover, with bolt 4 each LED lamp module is concatenated into one, isolate with the sleeve pipe 5 that is sleeved on the bolt 4 between two adjacent radiators 1, be concatenated into holistic modular high-power LED light fixture, and be fixed on the support.Whole lamp power reaches 240w, luminous flux 19000Lm, and after measured, the junction temperature of every LEDs all between 69.8 ℃-71.2 ℃, illustrates that every LEDs junction temperature temperature difference is very little, reliable operation.
