Abstract
The utility model discloses a heat dissipation LED lamp with a direct blowing type fan. The heat dissipation LED lamp with the direct blowing type fan comprises an LED light source, a substrate, cooling fins, the fan, a power supply, a lamp base, a lamp housing and a lamp shade, wherein a shell of the lamp is formed by the lamp base, the lamp housing and the lamp shade, the LED light source is installed on the substrate, the cooling fins are attached and fixed to the back side of the substrate, the fan is arranged on the cooling fins, and the power supply is fixed to the internal space of a lamp body above the fan. Air is directly blown to the substrate and the cooling fins through the fan, and circulation of air in an air duct is achieved through heat dissipation holes in the periphery of the lamp housing. According to the heat dissipation mode that convection is directly reinforced through the fan, heat is dissipated into the atmosphere directly, the heat resistance of a traditional LED lamp is greatly reduced, the heat dissipation effect is better, and the power can be greatly improved under the condition that the size is not changed.
Description
Technical field
The utility model relates to a kind of LED light fixture, relates in particular to a kind of fan straight blow type radiating LED lamp.
Background technology
Energy-conserving and environment-protective in recent years, start the fundamental policies that low-carbon (LC) society has become countries in the world, LED light source, as new generation of green lighting source, has demonstrated the unrivaled good characteristic of conventional light source aspect energy-saving and environmental protection, is widely used in road, square, the occasion such as indoor.
LED is as cold light source, and about 30% energy can be converted into light, and the energy of residue 70% is to distribute with the form of heat energy, and along with the use of LED lamp, temperature can increase, and in order to allow LED normally work, heat radiation just becomes the difficult problem that must solve.Generally adopt at present the method for radiator to realize heat radiation: in outdoor lighting, generally the volume of lamp is not had to strict requirement, it is larger that radiator can do, and can realize heat radiation faster, and the power of LED lamp can do very large; With respect to outdoor use LED lamp, indoor for its volume and attractive in appearancely just have a higher requirement, what so just cause that the volume of radiator can not do is very large, radiating rate is fast not, power does not increase yet, even if add that active heat removal is also difficult to accomplish do not increasing lamp body volume and increasing its radiating rate in the situation that attractive in appearance.
Having in the market the product of some active heat removal, is generally that in the middle of first the thermal conductance in light source being generally radiator to heat container, then fan is directly blowing radiator.The mode of this active heat removal is well more a lot of than the effect of passive heat radiation, but is still subject to aluminium base and transfers heat to the restriction of heat radiator thermal resistance.Be exactly that aluminium base is awfully hot under normal circumstances, and radiator is very cool.How can directly dispel the heat and become one of yoke of restriction LED development aluminium base.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of fan straight blow type radiating LED lamp is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of fan straight blow type radiating LED lamp, comprises LED light source, substrate, radiating fin, fan, power supply, lamp holder, lamp housing and lampshade; Wherein, the shell of lamp holder, lamp housing, lampshade composition light fixture; LED light source is arranged on substrate, and substrate back laminating is fixed wtih radiating fin, and radiating fin is provided with fan, and power supply is fixed on the lamp interior space of fan top.Described radiating fin is heronsbill shape, and the radial air channel of oriented surrounding.Described lamp housing has air port at the ducting outlet place that is positioned at radiating fin.
The beneficial effects of the utility model are, directly blow the mode of substrate by fan, light source substrate is directly dispelled the heat, the effect of not removing again radiating fin simultaneously, can must dispel the heat to light source to a greater extent, power supply is also arranged on ventilation route and can power supply be also dispelled the heat simultaneously.
Brief description of the drawings

Fig. 3 is heronsbill radiating fin embodiment schematic diagram;
In figure, light source 1, substrate 2, radiating fin 3, fan 4, power supply 5, lamp holder 6, lamp housing 7, lampshade 8, air port 9, air channel 10.
Detailed description of the invention
As shown in Figure 1, a kind of fan straight blow type radiating LED lamp, comprises LED light source 1, substrate 2, radiating fin 3, fan 4, power supply 5, lamp holder 6, lamp housing 7 and lampshade 8; Wherein, lamp holder 6, lamp housing 7, lampshade 8 form the shell of light fixture; LED light source 1 is arranged on substrate 2, the fixing radiating fin 3 of substrate 2 back side laminating, and radiating fin 3 is provided with fan 4, and power supply 5 is fixed on the lamp interior space of fan 4 tops.
Described radiating fin 3 is heronsbill shape, and the radial air channel 10 of oriented surrounding.
Described lamp housing 7 has air port 9 in 10 exits, air channel that are positioned at radiating fin 3.
Described fan 4 can directly blow to substrate 2 and radiating fin 3.
Described power supply 5 is positioned at the ventilation route of fan 4.
As shown in Figure 2, in the time that fan straight blow type radiating LED lamp is worked, fan 4 can directly blow to radiating fin 3 and substrate 2, and along the air channel 10 of radiating fin 3, goes out facing to the air port 9 in air channel 10 from lamp housing 7, and air port 9 has several, each air channel 10 that faces.Can greatly accelerate like this light fixture and extraneous heat exchange.
Be illustrated in figure 3 the heronsbill embodiment shape of radiating fin 3.From centre to the air channel 10 of surrounding radiation, can be the as far as possible few windage that reduces, accelerates internal-external heat exchange.
