Problems solved by technology

[0005] 2. The chromatic aberration and low color rendering index of high-pressure sodium lighting
When viewing objects in this light color, the visual perception is not clear, and there will be a sense of haziness, and the vision is not good.
In addition, the color rendering index of general high-pressure sodium lamps is only 23, and the color reduction is very poor.
[0007] 3. The actual energy-saving effect of high-pressure sodium lamps is not ideal
Therefore, the high-pressure sodium lamps used for road lighting use higher power, which greatly wastes the power consumption of road lighting.

Embodiment Construction

[0022] Figure 3 shows the outlines of two types of fluorescent lamps, Figure 3A Shown is a spherical fluorescent lamp including a lamp tube 1 . The shape of the fluorescent lamp can be made into various shapes according to the needs, Figure 3B A fluorescent lamp of another profile is shown, which is a multi-row planar profile. The improvement point of the present invention is not the shape of the fluorescent lamp or the fluorescent lamp tube, therefore, the shape of the fluorescent lamp will not be discussed further here. It should be understood that the features of the present invention described below can be applied to various shapes of fluorescent lamps.

[0023] As described in the summary of the present application, the most important feature of the present invention is to change the emission spectrum distribution of the conventional high pressure nano-lamp, and set the main peak of the emission spectrum of the illumination fluorescent lamp of the present invention in...

Abstract

This invention provides a road fluorescent lamp. A problem existing in traditional high-pressure sodium lamp is that the maximum light energy output concentrates at 580 nm which has low effective light flux and low exciting value to man's eye at neso-vision belonging to yellow light zone. This invented lamp includes a lamp characterizing in that the wavelength main peek value of fluorescence powder coated on the lamp is 516+ / -10nm and sub-peak values are 480+ / -10nm, 450+ / -10nm and 611+ / -10nm, the distribution of which comforms to the meso-vision spectrum sensitivity between bright and dark visions of man's eye.

Description

technical field [0001] The present invention relates to a fluorescent lamp, in particular to a fluorescent lamp for road lighting. Background technique [0002] Road lighting is an important part of the development and change of cities around the world. Lighting experts and human physiology experts agree that road lighting sources with high luminous efficiency, good color rendering, low energy consumption, long life and low light pollution are the development direction of road lighting in the future. At present, high-pressure sodium lamps with high luminous efficiency and long life are mainly used for road lighting, replacing traditional incandescent lamps and high-pressure mercury lamps, and becoming the most important road lighting lamps. However, with the continuous improvement of people's requirements for road lighting, research has found that there is a significant difference between the visual effect of the human eye on the night vision environment and the light outpu...
