A reflector is composed of a guide clamping groove which is made of special light alloy extruded section, and the inner side of the guide clamping groove is provided with vacuum coating reflecting sheets which are easily inserted and changed. Radiating light waves of the upward 2/3 of a light pipe can be collected to a high beam which is reflected to a lighting area. The illuminance of the utility model is increased by 4-5 times, under the condition of the same area, the lamp of 30 W can replace four lamps of 40 W, and the eletricity is enhanced by 4-5 times. The utility model can be widely used for the high space illuminating, such as an underground, a hall, a factory, etc.

Description

Long distance reflecting straight-tube fluorescent lamp

The utility model relates to the utilization reflecting curved surface and assembles strong beam, especially for the long distance reflecting straight-tube fluorescent lamp of subway station illumination.

According to examination investigation in many ways, also do not have the straight-pipe fluorescent lamp tool that beam effect is applicable to the space large tracts of land base lighting that 5M such as subway station, the hall, factory building, workshop are above.The illumination of current relevant above-mentioned environment because the space height does not have dedicated lamp, generally all is the maximum existing straight-pipe fluorescent lamp tool Fig. 1 that allows apart from height ratio 1.32 scopes of adapted.Because of after the radiation luminous energy of the high fluorescent tube in space arrives daylighting face, to get rid of and subtract greatly, illumination does not reach the national regulation lighting requirement.And,, only take intensive cloth lamp scheme at light fixture configuration design aspect in order to reach requirement, come so just to cause the high problem of power consumption and operating cost.It also is the problem that present subway station lighting field is badly in need of the update of research novel product.

The purpose of this utility model provides a kind of long distance reflecting straight-tube fluorescent lamp that uses reflecting curved surface to assemble strong beam, it can be effectively be converged to strong beam with the radiation luminous energy of fluorescent tube by reflector and reflexes to the daylighting district, strengthens the utilization rate of illuminance and light fixture light.

The purpose of this utility model is achieved in that long distance reflecting straight-tube fluorescent lamp by reflector, end cap and suction top handling attachment mechanism components pie graph 2.

1, reflector: one of critical component of this lamp, just be to put into effect reflector design scheme near the spotlight beam effect, adopt special-purpose light-alloy extrudate 6, the inboard establish be convenient to 7 bases of the attached replacing vacuum coating of embedding reflecting piece be PET synthetic material thickness 70 μ～100 μ lead draw-in groove 9, median 75 μ～95 μ establish symmetric points 10 in center line bottom decentre line 4mm, provide R concave curved surface 8, size range is R35mm～65mm, and the median scope is R40mm～60mm.From top datum line 3mm～8mm median is that 4mm～7mm provides horizontal plane 12 connects formation with R concave curved surface 7 single fluorescent tube, two fluorescent tube, four lamp reflector Fig. 3～4.

2, end cap 4: adopt the injection moulding of flame-proof ABS synthetic material, what its role is to guard shield reflector two ends fluorescent tube 11 patches lamp socket 5 or ballast, is shaped as ellipse garden streamlined, and with inhale top handling attachment mechanism and constitute this decorative lamp and appearance and modeling.

3, inhale top handling attachment mechanism: strengthen the injection moulding of PP synthetic material with flame-resistant high-temperature-resistant, described mechanism is by the suction top handling attachment 1 of laying ballast, and by changeing nail 2, angular adjustment deck 3 is slidingly connected with the reflector guide rail.And rotate lamp body 180 ° of scopes by demand and change irradiating angle, implement directional lighting.

The utility model and the prior art main performance table of comparisons are as follows:

From the table on as can be seen, compared with the prior art the utility model has following beneficial effect:

1, effectively utilizes the radiation light-wave that makes progress, increased the illuminance in daylighting district.1 30W surpasses the illumination of 4 40W.

2, because the radiation light-wave that makes progress is assembled strong beam by the R curved surface, increased the illumination in daylighting district, under same illumination requirement and same area environmental condition, prior art must need 4 40W, and the utility model only needs 1 30W just can surpass the illuminating effect of prior art, can economize on electricity 4～5 times.

3, compared with the prior art Luminaire efficiency and light fixture usage factor have improved 3 times.

4, owing to adopted the energy-conservation fluorescent tube of the high colour developing of three primary colours, colour rendering index reaches more than the 90Ra, has clear improvement on color reducibility and visual effect.

5, owing to adopted light fixture energy variable-angle, can increase irradiated area, reduce and use lamp quantity, improve the illuminating effect in daylighting district.
