The specific embodiment
Further specify below in conjunction with the structure of accompanying drawing the self-cooling LED lamp that the utility model proposed.
Like Fig. 1, Fig. 3 and shown in Figure 4, be the structural representation of self-cooling LED lamp.Its structure comprises the heat-radiating substrate 2 that is fixed with LED wick 1; On heat-radiating substrate 2, be fixed with reflection shield 3, heat dissipating housing 4 outside on the heat-radiating substrate 2 in the outside of reflection shield 3, being fixed with, outer heat dissipating housing 4 adopts good heat dissipation, lightweight thin aluminum sheet; Outer heat dissipating housing 4 can for one, two or more; The shape of outer heat dissipating housing 4 is similar with the shape of reflection shield 3, and the openend of the openend of outer heat dissipating housing 4 and reflection shield 3 is at a distance of certain distance, and the upper end of heat dissipating housing 4 is provided with discharge orifice 5 outside.When outer heat dissipating housing 4 was two or more, the openend of adjacent outer heat dissipating housing was at a distance of certain distance.The heat that the LED wick produces at first passes to heat-radiating substrate 2, and heat-radiating substrate 2 is the outer heat dissipating housing 4 of heat transferred, in the time of heat dissipating housing 4 heat radiations outside, at first improves near the temperature of outer heat dissipating housing 4 upper ends; Hot-air between outer heat dissipating housing 4 and the reflection shield 3 lightens, hot-air discharge orifice is run out of on the outer heat dissipating housing, and the space the first half formation negative pressure between heat dissipating housing 4 and the reflection shield 3 outside, cold air is up in the lower end of outer heat dissipating housing 4 and the slit between the reflection shield 3; In the up process of cold air, gradually the outer heat dissipating housing 4 of heat is lowered the temperature, and cold air heating gradually; Thereby go out from the convection current orifice flow, form cross-ventilation, greatly reduce the temperature of heat-radiating substrate and LED lamp; Radiating effect is better, has reduced the light decay in the use of LED lamp, has prolonged service life; And outer heat dissipating housing 4 can be very thin, makes whole LED lamp weight lighten, and production cost reduces; Certainly, reflection shield 3 also can adopt thin aluminum sheet, and radiating effect is better.
In order to reduce the weight of whole LED lamp, help the popularization of LED lamp in domestic lighting, as shown in Figure 2; Can smear heat-conducting cream 9 between the upper bottom surface with outer heat dissipating housing 4 and reflection shield 3, can also be fixing through welding, LED wick 1 is fixed on the upper bottom surface inside of reflection shield 3; The heat that the LED wick produces is directly passed to outer heat dissipating housing through reflection shield; Like this, overall weight alleviates greatly, and cost alleviates greatly.
When 4 the quantity of loosing outside the heat cover be two or more, the adjacent heat cover same convection channel of dispelling the heat that forms between 4 of loosing outward, more preferably greater than the outer heat dissipating housing 4 near the inboard, radiating effect is better like this near the diameter of the outer heat dissipating housing 4 in the outside.
Heat-radiating substrate 2 is up big and down small circular platform type, has step 5 at the periphery of heat-radiating substrate 2, and the top 41 of outer heat dissipating housing 4 is fixed on the step 5.It is more reasonable to make outer heat dissipating housing 4 arrange like this, good heat dissipation effect.As shown in Figure 5, heat-radiating substrate 2 can also have the spindle-type of step for periphery certainly, and like this, radiating effect is changed.
As shown in Figure 6, the openend of outer heat dissipating housing 4 has lace 6; Certainly, the openend of reflection shield 3 also can have lace 6.As shown in Figure 7, the openend of outer heat dissipating housing 4 can also have breach 7, has not only increased aesthetic measure, but also has improved radiating effect.
Like Fig. 1 and shown in Figure 5, above heat-radiating substrate 2, be provided with radiating fin 8, further improved radiating effect, reduced the temperature of heat-radiating substrate 2 and LED wick 1, reduced the light decay of LED lamp, prolonged service life.
