Abstract

The utility model relates to a broadside reflective straight pipe-shaped fluorescent lighting fixture which adopts three curved surfaces reflective width light beam, and is in particular used for indoor lightening. The utility model is made of special light aluminum alloy pressed bar material, and the internal lateral of the utility model is provided with a reflecting device formed by a guiding clamp groove and the reflecting device provides convenience for embedding and replacing a vacuum membrane plating reflector. The reflecting device can effectively reflect the radiating light wave the light pipe moving upward by two thirds to be a broad light beam radiating and light gathering area through the three curved surfaces. Compared with the prior art, the utility model has the advantages as follows: the lightening intensity is increased by 3 to 4 times, the radiated area is increased by once; under the condition of the same area, one 10 watt power lamp of the utility model can replace one 40 watt power lamp under the prior art and the utility model conserves electric energy by 3 to 4 times; therefore, the utility model is extensively used for indoor lightening.

Description

Straight-pipe fluorescent lamp with wide reflecting face

The utility model relates to utilization three camber reflection angles pencil of ray, especially for the straight-pipe fluorescent lamp with wide reflecting face of room lighting.

Present prior art straight-pipe fluorescent lamp tool Fig. 1 that generally uses, all be that the light pipe nature is to radiation all around, test after deliberation, the daylighting district has only utilized light pipe about 1/3rd luminous energy downwards, make progress about 2/3rds luminous energy of light pipe all has been dissipated on surroundings wall and the ceiling, how utilizing this luminous energy of 2/3rds to reach energy-efficient, is present room lighting problem anxious to be studied.

The purpose of this utility model provides a kind of straight-pipe fluorescent lamp with wide reflecting face of utilization three camber reflection angles pencil of ray, its can effectively fluorescent tube be made progress radiation luminous energy of about 2/3rds expands by three curved surface reflectors and is mapped to the daylighting district, increases the utilization rate of irradiated area and light fixture light.

The purpose of this utility model is achieved in that straight-pipe fluorescent lamp with wide reflecting face by three curved surface reflectors, end cap and suction top handling attachment mechanism components pie graph 2.

1, three curved surface reflectors: one of critical component of this lamp just is to put into effect to have and expands the three curved surface reflectors design power case of penetrating effect.Promptly adopt special-purpose light-alloy extrudate 6, the inboard is established and is convenient to the attached replacing vacuum coating of embedding reflecting piece 7, the sheet base be PET synthetic material thickness 100u lead draw-in groove 9.From base directrix 5mm, decentre line 3mm establishes symmetric points 10, provides R concave curved surface 8 in the center line bottom, and size range is R25mm～40mm, and the median scope is R30mm～35mm.Set up an office 11 in the center line bottom, from top datum line 2.5mm～4mm median 3mm～3.5mm, provide R concave curved surface 13, size range is R35mm～75mm median 40mm～70mm, connect with R concave curved surface 8, constitute single fluorescent tube, H type list fluorescent tube, two fluorescent tube three curved surface reflector Fig. 3～4 of H type.

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 12 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 three curved surface reflector guide rails.Can rotate lamp body by demand 140 ° of scopes 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 10W surpasses the illumination of 1 40W of prior art.

2, be angle pencil of ray because the radiation light-wave that makes progress expands to penetrate by R three curved surfaces, increased the illumination and the irradiated area in daylighting district.Under same illumination requirement and same area environmental condition, prior art only needs 1 10W just can surpass the illuminating effect of prior art with 1 40W, the utility model, can economize on electricity 3～4 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 three primary colours high-color rendering, 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, the illuminating effect in raising daylighting district by changing angle.
