Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the cutaway view of the utility model one embodiment shaft section;
Fig. 2 is the schematic perspective view of band section embodiment illustrated in fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is based on a specific embodiment of the track lamp of middle low power led light source.
The surface of light source front end of light source board 10 is provided with luminous intensity distribution device 20, and these luminous intensity distribution device 20 usefulness aluminium punching presses are made, and its inside has a reflective surface 23, and these reflective surface 23 swinging settings comprise axial big end 22 and one small end 21; Small end 21 is namely pressed close to light source board 10, arranges around led light source 11, and holds 22 light emission directions towards led light source 11 greatly, be i.e. horizontal left-hand among Fig. 1.In addition also has construction package 3, the fixed head 30 that construction package 3 comprises and a shell 40, wherein shell 40 is ccontaining light source board 10, luminous intensity distribution device 20 and fixed head 30, and fixed head 30 still is conducting-heat elements, has good thermal conductivity factor, fix and be matched with the inwall of shell 40, also fixing simultaneously, cooperated light source board 10. so, from led light source 11 to light source board 10, but all have thermal dissipating path between the fixed head 30. have an opening 41 of bright dipping at shell 40, this opening 41 is matched with the big end 22 of reflective surface 23, and light from led light source 11 was stimulated the menstrual flow can be from big end 22 after luminous intensity distribution spare 20 parts, opening 41 outputs.
Compare the high-power LED light source that uses equal power consumption, the led light source of middle low power is layed in makes pyrotoxin obtain disperseing on the light source board, just increase thereby its heat-conducting section of heat that same power consumption produces is long-pending, corresponding the obtaining of 30 thermal resistance cut down from led light source 11 to fixed head, heat is conducted quickly, thereby expanded total light efficiency of light fixture; Simultaneously, the combination of light source board 10, luminous intensity distribution device 20 and fixed head 30 is simple, with low cost; On the other hand, use a plurality of led light sources 11 to be laid on the light source board 10, when needs change lamp power, the density that can keep distribution led light source 11 on the light source board 10, and need not change its distribution area, therefore, can change the specification of luminous intensity distribution device 20, so provide favorable compatibility, the less cost of cost when making track lamp constitute serial scheme.
Present embodiment also has some other characteristics:
Fixed head 30 is the form of a flat board, is matched with on the light source board 10 and the surface of light source opposite surfaces, and the fixed head of this structure is very simple; And, having the upright wall always 31 of turnover in fixed head 30 outer peripheral edges, these straight wall 31 lateral surfaces are matched with the inner surface of shell 40, have thermal conducting path between the two.So the fixed head 30 of structure can and 40 on shell have lower thermal resistance, moulding simultaneously, install all very easy.The inwall of shell 40 is periphery, and its inwall is coaxial with luminous intensity distribution device 20, and this form is beneficial to the axisymmetric illumination effect of moulding.
Details aspect optics is, led light source 11 is uniformly distributed in the view field of small end 21 on this surface of light source, make the light-emitting zone brightness on the light source board 10 even, to such an extent as to the beam distribution that obtains from opening 41 is even, further, between the big end 22 of luminous intensity distribution device 20 and opening 41, have an astigmatism plate 50, can be used for to greatest extent the output beam of light fixture is carried out uniform treatment.
Luminous intensity distribution device 20 is to need specially designed parts, and the revolution bus of its reflective surface 23 comprises straight line, multistage line, circular arc and/or repeatedly curve etc. is multiple, to such an extent as to mate the distribution curve flux demand of different led light source 11 and track lamp.Especially, reflective surface 23 is divided into a plurality of little 24 structures, and little 24 can be the form of plane, concave surface and/or convex surface.Destroy the imaging effect of led light source 11 for this little 24, occurred the picture of led light source in the projection of avoiding light beam to export.
At opening 41 places of shell 40, have a contraction section that inwardly shrinks, inner big end 22 shapes with luminous intensity distribution device 20 of this contraction section cooperatively interact.
As shown in Figure 2, shell 40 has a back cavity 42 at this fixed head 30 with respect to the inside of light source board 10 axial opposed, is used for placing the driving power (indicating) that drives this led light source 11 in this back cavity 42.Shell 40 is used for connecting the installed part that can fix in orbit, and these installed parts that can mate existing track lamp are realized replacing easily.
The above only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
