Embodiment approach 1
[0025] Implementation mode one: if Figures 1 to 3 As shown, the light-expanding LED lamp of the present invention is mainly composed of an LED blue light chip 1 and a transparent light guide column 2, wherein the substrate 3 of the above-mentioned LED blue light chip 1 is provided with a surrounding wall 4 made of a heat-conducting plastic surface silver-plated, its The chip 5 is arranged in the wall 4, and the upper surface of the substrate 3 in the wall 4 is covered with a transparent heat-conducting layer 6. The lower part of the above-mentioned transparent light guide column 2 is provided with a cover plate 7, and the bottom surface of the cover plate 7 is provided with a matching LED blue light chip 1. Stepped groove, the side wall of the second stepped groove 8 and the upper surface of the cover plate 7 are provided with a reflective layer 9, the top surface is provided with a fluorescent layer 10, the top of the above-mentioned transparent light guide column 2 is provid...
Embodiment approach 2
[0033] Implementation mode two: if Figures 3 to 5 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the above-mentioned reflective structure is a reflector 12 arranged on the top of the transparent light guide column 2, and the bottom surface of the reflector 12 is provided with a reflective layer 9, which can be arranged on The light excited by the chip 5 in the middle part of the LED blue light chip 1 is reflected. Light reflection to achieve the effect of light expansion.
[0034] Wherein, in this embodiment, the transparent heat conduction layer 6 disposed in the upper surface wall 4 of the substrate 3 is made into a convex lens, and the transparent light guide column 2 is made of polycarbonate, and its cover plate 7 is integrated with the transparent light guide column 2 .
[0035] The enclosure wall 4 of this embodiment is made of brushed nickel plated on the copper surface.
Embodiment approach 3
[0036] Embodiment 3: This embodiment is basically the same as Embodiment 1, the difference is that the substrate 3 of the LED blue light chip 1 that matches the cover plate 7 is made of aluminum, and the wall 4 arranged on the substrate 3 is made of copper alloy The surface is made of brushed nickel, which makes it have a good reflective effect.
[0037] In this embodiment, the reflective structure arranged on the top of the transparent light guide column 2 is a cavity 11 with an irregular shape, and the cavity 11 is provided with a reflective layer 9 made of a copper alloy surface coated with brushed nickel.
[0038] The above-mentioned transparent heat-conducting layer 6 arranged in the surrounding wall 4 is made into a concave mirror to achieve the function of primary light distribution.
