Abstract

The present invention relates to a remote reflection type H-shaped fluorescent tube lamp which utilizes three curved surfaces to converge high beams and is particularly used for indoor illumination. By making use of special light alloy extruded section bars and a reflector which is formed in a mode that the inner side of the reflector is provided with a card guiding groove bringing convenience for embedding, attaching and replacing a reflection sheet with a vacuum coating, upward two thirds of a radiation light wave of a light pipe can be converged into a high beam irradiation lighting area. Compared with the prior art, the illuminance of the present invention is increased by 3 to 4 times. Under the same area condition, two lamps of 22W can replace four lamps of 40 W in the prior art, and electricity can be saved by 3 to 4 times. The present invention is widely used for distant illumination for high spaces, such as undergrounds, halls, waiting rooms, factories, etc.

Description

Reflecting fluorescent lamp with H-shaped tube

Affiliated technical field

The present invention relates to use three camber reflections to assemble strong beam, especially for the reflecting fluorescent lamp with H-shaped tube of room lighting.

Background technology

According to examination investigation in many ways, the H type fluorescent tube light fixture that is applicable to the above space of 6m large area lighting that does not also have the convergent pencil of rays effect.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 high 1.32m scope 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, aspect the light fixture configuration, only take intensive cloth lamp scheme in order to reach requirement, come so just to cause the high problem of power consumption and operating cost.It also is the update problem that long distance lighting fields such as present subway station, the hall, waiting room, factory building are badly in need of the research novel product.

Goal of the invention

The purpose of this invention is to provide a kind of utilization three camber reflections and assemble the reflecting fluorescent lamp with H-shaped tube of strong beam, it can be effectively be converged to strong beam irradiation daylighting district with the radiation luminous energy of H type fluorescent tube by three curved surface reflectors, strengthens the utilization rate of illuminance and light fixture light.

Technical scheme

The object of the present invention is achieved like this: reflecting fluorescent lamp with H-shaped tube is by three curved surface reflectors, end cap and inhale top handling attachment mechanism components pie graph 2.

To contrast accompanying drawing Fig. 3 below and describe the specific embodiment of the present invention

1, three curved surface reversers: 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 0.110mm lead draw-in groove 9.Establish symmetric points 10 in center line bottom decentre line 6mm and be the center of circle, provide radius (R) size and constitute curved surface 8, size range is R65.5mm-R70mm, and the median scope is R66-R69mm.Setting up an office in the center line bottom 11 is the center of circle, provides radius (R) size from top datum line 8.5mm and constitutes curved surface 13, is of a size of R151mm.Connect the three curved surface reflector Fig. 3-4 that constitute monochromatic light pipe, two light pipes with curved surface 8.

2, end cap 4: adopt the injection moulding of flame-proof ABS synthetic material, peg graft with the reflector two ends, what its role is to guard shield reflector two ends fluorescent tube 12 patches lamp socket 5 or ballast, and with inhale top handling attachment mechanism and constitute the decoration and the appearance and modeling of this light fixture.

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 constitutes, and is slidingly connected with three curved surface reflector head rail.Can rotate lamp body by demand 160 ° of scopes and change irradiating angle, implement directional lighting.

Beneficial effect

The present invention and the prior art main performance table of comparisons are as follows:

From showing and can find out, compared with the prior art the present invention has following beneficial effect:

1, effectively utilize the radiation light-wave that makes progress and assembled strong beam by three camber reflections, increased the illumination in daylighting district, Under same illumination requirement and the same area environmental condition, prior art must need 4 40w, and the present invention only needs 1 22W * 2 with regard to energy Surpass the illuminating effect of prior art, can economize on electricity 3～4 times.

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

3, owing to adopted high power factor electronic ballast and 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, has satisfied the requirement of green illumination fully.

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