Abstract
The utility model discloses a broad-band sodium-vapor lamp for the tunnel illumination, comprising two big wrap angle metal cylindrical reflectors and two high-pressure sodium-vapor lamp pipes. The openings of two cylindrical reflectors are in arrangement of surface to surface, reaching the specific long and narrow broad-band illuminating effect in the long tunnel. The utility model has the advantages of far lighting distance, dazzle resistance, energy saving, shock resistance, etc.
Description
The utility model belongs to a kind of improvement of lighting.
The long Railway Tunnel illumination is the problem of not properly settling for many years.Existing high-pressure mercury lamp light source is used for tunnel illumination and is easy to generate dazzle, and is similar to railway block section yellow signal light because of the high-pressure mercury lamp light source is golden yellow, and it is dazzle or signal light that the driver is difficult for differentiating, and influences traffic safety.If use other light source lamp, range is short, and light efficiency is low, does not reach energy-saving effect.Iodine-tungsten lamp and high-pressure sodium lamp limit because of being subjected to tunnel space, and illumination is poor, and Luminance Distribution is inhomogeneous.Existing a kind of light fixture (the Japanese illumination meeting publication " illumination in 1978 that utilizes two reflectors to place back-to-back of Japan
" table 9-16 diagrammatic sketch in the works).This light fixture has wide light belt, the characteristics of long range.But belong to direct illumination type light fixture, dazzle is big, and rolling driver eyes also are not suitable for the long Railway Tunnel illumination.
The purpose of this utility model provides the illuminating wide light belt of a kind of suitable long Railway Tunnel, high efficiency tunnel illumination light fixture.This light fixture direct projection dazzle and reflected glare are all smaller, can guarantee traffic safety in the tunnel, and energy consumption is also low.
The utility model adopts the face of cylinder, parabola and ellipsoid to combine as two big cornerite cylindrical reflectors.Place on the opening surface opposite of two big cornerite metal cylindrical reflectors, and two bases are on same horizontal plane.Big cornerite metal cylindrical reflector top connects with shadow shield, establishes a high-pressure sodium light modulation pipe in the reflector of each big cornerite metal cylinder.
According to the specified conditions of the long and narrow illumination in tunnel with in order to guarantee traffic safety in the tunnel, two big cornerite metal cylinder slotted-type reflector surface opposites arrange that the wide light belt low angle range both sides of its formation can reach 30m, apart from than up to 8; And two wide light belt light sources superpose mutually, have improved the illuminance of superposed positions, have guaranteed that the rail level minimal illumination is not less than 1LX.Next utilizes big cornerite metal cylindrical reflector can reduce the direct projection dazzle.Shielding angle is limited in 7 ℃.Simultaneously, each cylindrical reflector can utilize the base of opposite big cornerite metal column reflector again, prevents to produce reflected glare.
The utility model with high-pressure mercury lamp as light source, because of the luminous efficiency of high-pressure mercury lamp reaches 90Lm/W, when the tunnel intraoral illumination, advantage such as strong to the penetrability of vaporific gas and dust, that the life-span is long.
Another characteristics of the present utility model are on two hooks of light fixture and lamp socket damping device to be housed respectively.
Below in conjunction with accompanying drawing the utility model is described in detail as follows:
Fig. 1 is the big cornerite metal of a wide light belt sodium lamp tunnel light fixture cylindrical reflector side view
Fig. 2 is a wide light belt sodium lamp tunnel light fixture installation diagram
Fig. 3 is a wide light belt sodium lamp tunnel light fixture side sectional view
Big cornerite metal cylindrical reflector 1 is made up of the face of cylinder 2, the face of cylinder 3, ellipsoid 4 and parabolic 5.Between two big cornerite cylindrical reflectors 1, couple together with a V font shadow shield 6.
Two links of lamp housing 7 usefulness 8 are fixing, are provided with damping spring 9 in the link 8, and trigger 10 and rectifier 11 and are fixed by bolts on the shell 7 between the top and shadow shield 6 of shell 7, and the base of reflector 1 is fixed on the bottom of shell 7.
High-pressure mercury lamp 12 is contained on the porcelain spare lamp holder 13.Rubber shock-absorbing pad 14 is arranged in the lamp holder 13.Lamp socket is made up of quick change fluorescent tube mechanism 15, lamp holder sealing ring 16 and light cover 17.
Light fixture is direct floodlight setting sun type light fixture.Because of the single-track railway tunnel is provided with a refuge chamber every 60m, all lay a light fixture above the refuge chamber at each, can play the effect that keeps away car indicator lamp and vehicling lighting simultaneously.
Embodiment:
Big cornerite metal cylindrical reflector 1 is by radius R
1The face of cylinder 2 of=59mm, radius R
2The parabola 5 of the face of cylinder 3 of=82mm, the ellipsoid 4 of focus C=180mm and focal distance f=22mm is formed.Between two big cornerite cylindrical reflectors 1, couple together with a V font shadow shield 6.
The utility model compared with prior art has the following advantages:
The wide light belt luminous intensity distribution that reflector forms is far away according to distance, luminescent effect and light source utilization rate height, and energy consumption is low; Reduce direct projection dazzle and reflected glare, do not affected Si and take advantage of Ren person lookout, can guarantee the safety of driving a vehicle. In addition, also have shockproof, moistureproof and etch-proof performance.
