The technical solution adopted in the present invention is: the present invention includes LED heat-radiating substrate, metal heat sink, housing, drive circuit board component, fixedly connected at least one led chip on the described LED heat-radiating substrate, described metal heat sink is connected with described LED heat-radiating substrate and heat loss through conduction, described drive circuit board component is positioned at described housing, described LED light fixture also comprises radiator fan, and described metal heat sink is between described radiator fan and described LED heat-radiating substrate.
Described LED light fixture also comprises reflector, and described LED heat-radiating substrate is positioned at described reflector together with described led chip.
Described reflector adopts the thermal conductive metallic material manufacturing, and the afterbody of described reflector contacts with described metal heat sink and dispels the heat.
Described LED light fixture also comprises ring-shaped article, shell fragment, clamp is installed, and described ring-shaped article is placed in the opening part of described reflector, and described installation shell fragment, described clamp are connected with described ring-shaped article.
Described LED light fixture also comprises holder, and described metal heat sink and described radiator fan are fixedly connected by described holder.
All be fixedly connected with a cofferdam in the periphery of each described led chip on the described LED heat-radiating substrate, be filled with fluorescent material and optical resin in the described cofferdam.
Described LED heat-radiating substrate is provided with the LED protective cover together with the outside of described led chip.
Described housing is provided with louvre.
Described metal heat sink is a gilled radiator.
The invention has the beneficial effects as follows: owing to the present invention includes the LED heat-radiating substrate, metal heat sink, fixedly connected at least one led chip on the described LED heat-radiating substrate, described metal heat sink is connected with described LED heat-radiating substrate and heat loss through conduction, described LED light fixture also comprises radiator fan, described metal heat sink is between described radiator fan and described LED heat-radiating substrate, when illumination work of the present invention, described radiator fan is together running also, can produce heat when described led chip is luminous, the heat that is produced is transmitted to described metal heat sink by described LED heat-radiating substrate, described metal heat sink is dispelled the heat as existing radiator " passive type ", a part of heat is dispersed in the ambient air, simultaneously, under the effect of described radiator fan, another part heat can be siphoned away or blow away by described radiator fan, produced the forced heat radiation effect of " active " heat radiation, so good heat dissipation effect, can avoid led chip at high temperature to work, effectively increase the service life, because the existence of forced heat radiation, therefore can dwindle the volume of described metal heat sink, so the present invention is simple in structure, volume is little, excellent in heat dissipation effect, long service life;
Because reflector of the present invention adopts the thermal conductive metallic material manufacturing, the afterbody of described reflector contacts with described metal heat sink and dispels the heat, the heat that produces when therefore described reflector also can be worked led chip distributes a part, so radiating effect of the present invention is better;
Because the present invention also comprises ring-shaped article, shell fragment, clamp is installed, described ring-shaped article is placed in the opening part of described reflector, and described installation shell fragment, described clamp are connected with described ring-shaped article, so the present invention can be used as Ceiling light, be installed on the ceiling, so the present invention has wide range of applications;
Owing to all be fixedly connected with a cofferdam in the periphery of each described led chip on the LED heat-radiating substrate of the present invention, be filled with fluorescent material and optical resin in the described cofferdam, described cofferdam makes when filling fluorescent material and optical resin in process of production, fluorescent material and not overflow of optical resin, effective, so production efficiency height of the present invention.
