Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as figure 1 As shown, the energy-saving reflector of the present invention includes a first parabolic hole 1 and a second parabolic hole 2 arranged side by side. The cross-sectional shape of the first parabolic hole 1 and the cross-sectional shape of the second parabolic hole 2 are both parabolic. Both the inner walls of the parabolic hole 1 and the second parabolic hole 2 are mirror surfaces;
[0016] The first phosphor 3 is a yellow phosphor (YAG:Ce 3+ ) or red phosphor (CaAlSiN 3 :Eu 2+ ); the second phosphor 4 is red phosphor (CaAlSiN 3 :Eu 2+ ) or yellow phosphor (YAG:Ce 3+ ). When in use, the first fluorescent powder 3 and the second fluorescent powder 4 are fluorescent powders that can emit light of different colors after being illuminated.

Abstract
The invention discloses an energy-saving reflector for traffic safety indication, which comprises a first parabolic hole and a second parabolic hole arranged side by side, the inner walls of the first parabolic hole and the second parabolic hole are both mirror surfaces; the first parabolic A first fluorescent powder is packaged in the hole, a second fluorescent powder is packaged in the second parabolic hole, and the first fluorescent powder and the second fluorescent powder are fluorescent powders that can emit light of different colors. The energy-saving reflector can gather the light from the vehicle lights on the high-brightness phosphor, and excite the phosphor to emit light. After the driver sees the energy-saving reflector and reflects the light, he will get a warning or danger signal, and drive carefully to prevent traffic accidents. occur. The energy-saving reflector can be used as a new type of safety indication signal display without power supply, and has the advantages of energy saving and environmental protection.
Description
technical field [0001] The invention belongs to the application field of fluorescent material traffic safety indication, and relates to a commercial yellow fluorescent powder (YAG:Ce 3+ ) and red phosphor (CaAlSiN 3 :Eu 2+ ) and its reflector. Background technique [0002] The use of phosphors as luminescence conversion materials has the advantages of energy saving, environmental protection, small size and stable luminescence performance, and is the most promising next-generation solid-state luminescent light source. Commercial yellow phosphor YAG:Ce 3+ and red phosphor CaAlSiN 3 :Eu 2+ It can be excited by natural light, has extremely high luminous efficiency, excellent color rendering index and good stability, and can be designed as a visible light reflector for traffic safety indication. At present, the road traffic safety instruction measures are not complete, and there are still a large number of traffic safety accidents every day, especially at road bends. Traffi...
