EXAMPLE III

On the basis of the above embodiments, the present embodiment describes in detail the LED light source of the intelligent landscape lamp provided by the present invention. Fig. 3 is a schematic structural diagram of a high-power LED lamp according to an embodiment of the present invention, including: a heat dissipation substrate 21, a first packaging layer 22, a second packaging layer 24, and a plurality of spherical lenses 23; the first encapsulation layer 22 is located on the heat dissipation substrate 21, the ball lens 23 is at least partially embedded in the first encapsulation layer 22, and the second encapsulation layer 24 is located on the non-embedded portion of the ball lens 23 and the first encapsulation layer 22.

The high-power LED lamp adopts the spherical lens, solves the technical problem of insufficient concentration of the illumination brightness of the light source, does not need secondary shaping, has a simple structure and reduces the production cost. In addition, compared with the prior art, the method does not need to coat fluorescent powder on the chip, and solves the problem of brightness reduction caused by the reduction of the quantum efficiency of the fluorescent powder caused by high temperature.

In one embodiment, referring to fig. 4, a surface of the heat dissipation substrate 21 has a plurality of slotted channels 1 arranged in parallel, and the heat dissipation substrate 21 has LED chips arranged thereon. The slotted hole passage is a semi-cylindrical slotted hole passage.

Because the safe junction temperature of the LED chip during working is within 110 ℃, if the junction temperature is too high, a series of problems such as light intensity reduction, spectrum deviation, color temperature rise, thermal stress increase, accelerated chip aging and the like can be caused, the service life of the LED is greatly reduced, and meanwhile, the accelerated aging of a silica gel layer packaged on the chip can be caused to influence the light transmission efficiency of the LED. Because only a part of energy in the input power of the LED is converted into light energy, and the other energy is converted into heat energy, for the LED chip with larger power, in order to improve the heat dissipation effect, the original heat dissipation substrate is processed to obtain the heat dissipation substrate with the groove body structure. Referring to fig. 4, the groove body is a channel for air circulation, and the heat dissipation effect is increased by using the heat convection of air. The diameter of the groove body is 0.3mm-2 mm. Under the size, the size of the air duct can be increased as much as possible under the condition that the strength of the heat dissipation substrate is not changed.

In one embodiment, the first encapsulating layer 22, the second encapsulating layer 24 and the ball lens 23 are all of a silicone structure. The second encapsulation layer 24 is a convex structure. Specifically, the shape may be a hemisphere, an ellipsoid, or the like.

In one embodiment, the volume of the embedded portion of the ball lens 23 embedded in the first encapsulation layer 22 is the same as the volume of the non-embedded portion. That is, the ball lens is half embedded in the first encapsulating layer, and the other part is wrapped by the second encapsulating layer.

In one embodiment, the first encapsulant layer 22 has a refractive index less than the second encapsulant layer 24, and the ball lens 23 has a refractive index greater than the second encapsulant layer 24. According to the invention, the silica gel with different refractive indexes is adopted, and the lens is formed in the silica gel, so that the problem of light emission dispersion of the LED chip is solved, the light emitted by the light source can be more concentrated, and the utilization rate of the light source is improved. In this embodiment, the refractive index of the second silica gel layer is 1.4-1.6. For example, methyl (1.41 refractive index) silicone rubber, phenyl high refractive (1.54 optical refractive index) silicone rubber can be selected. The refractive index of the silica gel layer is increased from bottom to top in order to inhibit total reflection, and the total reflection causes less emergent light, so that the light totally reflected to the inside is absorbed and becomes useless heat. And the refractive index of the outermost layer is not too large, because the refractive index of the outermost layer of silica gel is too large, the difference of the hit refractive index between the outer layer and the air is formed, the total reflection effect is serious, and the light transmission is not facilitated.

In one embodiment, the spherical lenses 23 form a regular array on the first encapsulation layer 22. Specifically, the array may be a rectangular array, a diamond array, a triangular array, a circular array, or the like.

In a specific embodiment, the first silica gel layer directly contacts the RGB three-primary-color LED on the package heat dissipation substrate, and a schematic structural diagram of the first silica gel layer is shown in fig. 5. Since the phosphor is in the form of particles, the light emission rate is decreased. The problem of uneven light emission caused by the fact that fluorescent powder is unevenly doped in the material can be solved by adopting the RGB lamp wick.

The distance between two adjacent spherical lenses 23 is 10 μm to 200 μm. The diameter of the spherical lens 23 is 10 μm to 200 μm. By adopting the size, the concentrated light source as much as possible can be ensured under the condition that the area of the radiating substrate is certain, and the utilization rate of the light source is improved.

In one embodiment, the heat dissipation substrate 21 is an aluminum plate. The thickness of the aluminum plate is 0.5mm-10 mm. The aluminum heat dissipation substrate has large heat capacity, is not easy to deform, is tightly contacted with the bottom surface of the heat dissipation sheet, and has good heat dissipation effect.

and c2, coating lens silica gel on the upper part of the lower hemispherical structure by using the first hemispherical mold to correspondingly form an upper hemispherical structure, wherein the lower hemispherical structure and the upper hemispherical structure are combined to form a spherical lens.

Step d: and (6) packaging.

d1, forming a hemispherical convex structure on the second packaging layer by using a second hemispherical mold;

d2, baking the packaging heat dissipation substrate at a second preset temperature for a second preset time;
