Ellipse-multi-curved-surface combined-concentrating high-reflectivity light distribution bulb and manufacturing method thereof

Abstract

The invention discloses an ellipse-multi-curved-surface combined-concentrating high-reflectivity light distribution bulb and a manufacturing method thereof, and relates to the illumination field. The light distribution bulb comprises a bulb shell which is made through blowing according to the light distribution requirement of ellipse-multi-curved-surface combined concentrating; one part of the inner surface of the bulb shell is treated through vacuum reflective plating to form a multi-curved-surface focusing mirror according to the light distribution requirement of ellipse-multi-curved-surface combined concentrating; the other part of the inner surface of the bulb shell is not plated to form a light transmission surface, and the bulb shell is divided into a reflection part and a light transmission part; a wick support is arranged in the bulb shell, and a ceramic metal-halide wick is fixed on the wick support and located on the concentrated focus axis of the multi-curved-surfacefocusing mirror. According to the ellipse-multi-curved-surface combined-concentrating high-reflectivity light distribution bulb and the manufacturing method thereof, the reflective surface and the focusing curved surfaces are best optimized, the focusing effect can be effectively improved, energy sources are fully utilized, and the bulb almost can be applied to all the illumination fields.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a light distribution bulb with high reflectivity and a manufacturing method thereof. Background technique [0002] At present, most of the lighting methods in public places in my country are high-pressure sodium lamps and LED lamps. The color rendering of high-pressure sodium lamps is poor, so the light is yellowish, the light is dim, the color is distorted, and the resolution is poor; and due to the problem of sodium leakage, high-pressure sodium lamps will cause light decay due to sodium leakage. The blue light content of LED lights is high, which can cause great damage to the retina; and because of its short wavelength and strong refraction, it has large glare, glare, and weak penetrating ability. It is not suitable for urban main and secondary arterial roads and workshop lighting. Its average color rendering The index (CRI) is low, and the color difference is heavy under the illumina...

AI Technical Summary

Problems solved by technology

The color rendering of high-pressure sodium lamps is poor, so the light is yellowish, the light is dim, the color is distorted, and the resolution is poor; and due to the problem of sodium leakage, high-pressure sodium lamps will cause light decay due to sodium leakage

The blue light content of LED lights is relatively high, which can cause great damage to the retina; and because of its short wavelength and strong refraction, it has large glare, glare, and weak penetrating ability. It is not suitable for urban main and secondary roads and workshop lighting. Its average color rendering The index (CRI) is low, and the color difference is serious under the illumination of LED light

LEDs are greatly affected by temperature, and street lamps have high power density and poor heat dissipation conditions, so the spectral drift of LED lamps is large and the light decays quickly

[0003] High-pressure sodium lamps and LED lamps mostly adopt the structural form of "wick + glass bulb shell + outer metal reflector". The outer surface of the metal reflector is easily oxidized under high temperature conditions, and the reflection focus point is single and uncontrollable, resulting in a large energy waste.
