Lighting module 200 is to be arranged by multiple illuminating devices 210 and constituted, and is COB (Chip On Board) type, more
A LED210 is arranged on the substrate of straight line belt shape and is formed.Multiple lighting modules 200 are in the periphery of heat-radiating rod 100
Face is adhered to along the length direction of heat-radiating rod 100.Wherein, the outer peripheral surface of heat-radiating rod 100 is also provided with ceramic wafer, makes to illuminate mould
Block 200 and heat-radiating rod 100 insulate, and the heat of lighting module 200 can be effectively transmitted to heat-radiating rod 100.When setting ceramics
When plate, the outer peripheral surface of heat-radiating rod 100 can adhere to the ceramic wafer for being equivalent to 200 quantity of lighting module, adhere on the ceramic wafer and shine
Bright module 200.
The lighting module 200 can be attached to each face of multi-panel prism heat-radiating rod 100, when heat-radiating rod 100 is 16 sides
When shape, the quantity of lighting module 200 is also 16.Moreover, each internal arrangement of lighting module 200 has illuminating device 210, i.e.,
LED210, a column, two column, three column etc. adjust the columns and quantity of LED210 according to required luminosity.
Reflector 300 is formed with other end open container shape, and central portion insertion is fixed with heat-radiating rod 100.It is described anti-
Light shield 300 plays the role of reflecting the light emitted by lighting module 200 and opening is irradiated, for this purpose, the quantity of setting
The multiple plate shape reflecting plates 310 for being equivalent to 200 quantity of lighting module are continuously formed in a manner of engaging by mutual side.And
And the outside of the reflector 300 can also be further arranged outside reflector in the form of wrapping the lateral surface of reflector 300
Shell 320, reflector 300 can be protected under external impact.
Reflecting plate 310 is bent and extended second reflection by the first reflecting plate 311 and from the other end of the first reflecting plate 311
Plate 312 is constituted, one end of the first reflecting plate 311 directly engaged with the outer peripheral surface of heat-radiating rod 100 or be inserted into heat-radiating rod 100
Heat-radiating rod insertion section 313 connects.It is excellent when the reflecting plate 310 is formed in such a way that the side of multiple reflecting plates 310 connects
Selection of land, the width to pass through become larger and are formed, so that its shape forms container shapes.
Preferably, the angle that the first reflecting plate 311 of the reflecting plate 310 and the length direction of heat-radiating rod 100 are formed is more
The angle formed less than the length direction of the second reflecting plate 312 and heat-radiating rod 100.This is to sent out by lighting module 200
When the light penetrated is sent out from the opening portion of reflector 300, in a manner of forming small angle with the length direction of heat-radiating rod 100 as far as possible
Irradiation light makes light with bigger angle is bent from the first reflecting plate 311 and is reflected.
In addition, spreading and emitting at a certain angle from the light that lighting module 200 emits, in order to make from 200 edge of lighting module
The light of length direction diffusion is reflected into the front of opening portion, and the length of the first reflecting plate 311 is greater than the length of lighting module 200.
Preferably, length when the first reflecting plate 311 being projected on the length direction line of heat-radiating rod 100 is greater than lighting module 200.
Due to the structure of this reflecting plate 310, the light emitted from lighting module 200 is reflected into the first reflecting plate 311 first,
At this point, the light that is reflected with excessively big angle of the length direction relative to heat-radiating rod 100 can be again by from the first reflecting plate 311
Bending and the second reflecting plate 312 formed relative to the length direction of heat-radiating rod 100 form smaller angle and to reflectors 300
Opening portion direction irradiation.Also, with the angular spread of the first reflecting plate 311 of disengaging from the light that lighting module 200 emits
Light is directly reflected into the second reflecting plate 312, at this point, since the angle that spreads from lighting module 200 is sufficiently big, by the
The angle of two reflecting plates 312 reflection can form sufficiently small angle relative to the length direction of heat-radiating rod 100.
Therefore, all light emitted by lighting module 200 irradiate after being reflected by reflecting plate 310, therefore prevent dazzling sense, shine
The track of the light in 300 front of reflector is mapped to there is no too big difference, minimizes the light being lost on the outside of irradiation area,
It can ensure bigger light quantity.Moreover, because the quantity 1 of the quantity of lighting module 200 and reflecting plate 310:1 is corresponding, from each photograph
The light that bright module 200 emits be reflected into each reflecting plate 310 ratio and angle it is same to each other, therefore light will not lay particular emphasis on a little from
And uniform luminosity can be obtained.
In addition, what the length direction that the first reflecting plate 311 and the second reflecting plate 312 are respectively relative to heat-radiating rod 100 was formed
Angle and the length of the first reflecting plate 311 and the second reflecting plate 312 are optionally fitted according to required irradiation area range
With.For example, substantially increasing length of first reflecting plate 311 relative to heat-radiating rod 100 when to concentrate light quantity to narrow irradiation area
The angle that direction is formed is spent, on the contrary, substantially reducing the angle that the second reflecting plate 312 is formed relative to the length direction of heat-radiating rod 100
Degree, thus when the light reflected by the first reflecting plate 311 is in and is similarly in the range of the second reflecting plate 312 of reflecting plate 310,
It is reflected into inside by the second reflecting plate 312 again, and light quantity is focused on central portion, and thus can become can be realized narrow and remote
The lighting device of radiation modality.Another example is, when to concentrate light quantity to wide irradiation area, it is anti-substantially to reduce first
The angle that plate 311 is formed relative to the length direction of heat-radiating rod 100 is penetrated, substantially increases the second reflecting plate 312 relative to heat-radiating rod
The angle that 100 length direction is formed, to be configured another reflecting plate again by the light that the first reflecting plate 311 reflects
310 the second reflecting plate 312 reflection, for reflection angle towards outside reflector, thus can become can be realized narrow and remote photograph
Penetrate the lighting device of mode.Moreover, the reflector superposition preparation with a variety of reflecting plate angles is multiple, it then can be according to need
It alternatively to use, the angle of reflecting plate 310 can diffusion angle, the first reflecting plate according to the LED210 by lighting module 200
311 and second the result of the calculating such as length of reflecting plate 312 determine.

Preferably, the side periphery of insertion 410 part of radiator of heat-dissipating pipe 420 is towards another side of radiator 410
Exposure, exposure portion can be contacted directly with heat-radiating rod 100 or heat-removal bar 110 on the outside of portion.For this purpose, the exposure portion of heat-dissipating pipe 420
It is formed in the form of flat, the exposure portion of heat-dissipating pipe 420 and the other end of radiator are in plane.
In addition, heat-dissipating pipe 420 is the structure for penetrating through multiple heat sinks 430.Wherein, the periphery face contact of heat-dissipating pipe 420 dissipates
Hot plate 430 is transmitted to heat sink 430 by the heat that heat-dissipating pipe 420 conducts, and is released in air by heat sink 430.And
And heat-dissipating pipe 420 is also settable multiple, penetrates through the different location of heat sink 430, and penetrate through from the different directions of heat sink 430
And it constitutes.
Also, although the heat-dissipating pipe 420 for penetrating through heat sink 430 can also be made to contact all heat sinks 430, by suitable
It is seen on the characteristics of sequential heat-dissipating pipe for leading to multiple heat sinks 430, if all heat-dissipating pipes 420 contact all heat sinks 430, outside dissipates
