Problems solved by technology

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. Traffic accidents are easy to occur at night. If a set of safety indicator signal displays can be installed at the bends, it can be greatly reduced. occurrence of traffic accident

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.

[0017] The principle of the energy-saving reflector of the present inventi...

Abstract

The invention discloses an energy-saving reflector for traffic safety indication, which comprises a first parabola hole and a second parabola hole which are arranged side by side, and the inner wall of the first parabola hole and the inner wall of the second parabola hole are mirror surfaces; first fluorescent powder is packaged in the first parabola hole, second fluorescent powder is packaged inthe second parabola hole, and the first fluorescent powder and the second fluorescent powder are fluorescent powder capable of emitting light of different colors. The energy-saving reflector can converge light rays emitted by a vehicle lamp on the high-brightness fluorescent powder to excite the fluorescent powder to emit light, a driver obtains careful or dangerous signals after seeing the energy-saving reflector reflecting the emitted light, cautious driving is achieved, and traffic accidents are prevented. The energy-saving reflector can be used as a novel safety indication signal display,does not need to be electrified, and has the advantages of energy conservation 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...
