Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0023] Please also refer to Figure 1 to Figure 3 , the first embodiment of the present invention provides a miner's lamp reflector 100, which has a cavity 50, and the miner's lamp reflector 100 includes a first reflective surface 10, a second reflective surface 20, and a third reflector corresponding to the cavity 50 Noodles 30.

[0024] In this embodiment, the first reflective surface 10 is an ellipsoid, and the ellipsoid meets the ellipse agenda:

[0025] x 2 110.5 + y 2 138.0625 = 1

[0026] The second reflective surface 20 is connected to the first reflective surface 10, and the second reflective surface ...

Abstract

The invention relates to a mine lamp reflector which is provided with a cavity and comprises a first reflecting surface, a second reflecting surface and a third reflecting surface. The first reflecting surface, the second reflecting surface and the third reflecting surface correspond to the cavity, and the first reflecting surface is an ellipsoidal surface; the second reflecting surface is connected with the first reflecting surface and is a parabolic surface; the third reflecting surface is connected with the second reflecting surface, the second reflecting surface is positioned between the first reflecting surface and the third reflecting surface, and the third reflecting surface is a cylindrical surface. The invention further relates to an illuminating device with the mine lamp reflector. The mine lamp reflector and the illuminating device with the mine lamp reflector have the advantages of maximum central light intensity, positive and negative 60-degree light spot sizes and capability of meeting light distribution requirements and illuminating requirements of mine lamps for coal mines.

Description

technical field [0001] The invention relates to the field of lighting, and more particularly to a miner's lamp reflector and a lighting device using the miner's lamp reflector. Background technique [0002] As the luminous flux and luminous efficacy of light emitting diodes (Light Emitting Diode, LED) continue to increase, the application of LEDs in various lighting fields is also becoming more and more extensive. However, the cosine distribution of the light intensity of LEDs is difficult to meet the requirements of different lighting fields in most cases. For example, in the field of miner's lamps in the coal industry, it needs to be no less than 30 degrees vertically upward and no less than 60 degrees vertically downward , within the range of not less than 45 degrees in the horizontal direction, a light spot with a light intensity of not less than 1cd (candela, candela) is formed, and the maximum central light intensity is not less than 1500cd. Therefore, it is particular...
