Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1, a kind of LED glass spot light for show window illumination, comprises diaphotoscope 1, Glass lamp base 2, screw socket 3 and is arranged on LED light source 4, LED light source substrate 5, primary event mirror 6, secondary reflection mirror 7 and the driving power 8 in Glass lamp base 2.
Diaphotoscope 1 is the circular flat glass of surface through frosted process, beam angle is smaller, and be arranged on the top of Glass lamp base 2, screw socket 3 is arranged on the bottom of Glass lamp base 2, primary event mirror 6 is arranged in secondary reflection mirror 7, and be provided with LED light source substrate 5 between the contact surface of primary event mirror 6 and secondary reflection mirror 7, LED light source 4 is arranged on LED light source substrate 5.
Diaphotoscope 1 is connected on Glass lamp base 2 by resistant to elevated temperatures silica gel sealing, also plays the effect of fixing secondary reflection mirror 7 simultaneously.
LED light source substrate 5 is the aluminium alloy base plate that 1.5mm is thick, and the heat dispersing out when LED light source 4 can be lighted conducts as early as possible; Meanwhile, primary event mirror 6 is close to again by secondary reflection mirror 7, disperseed again the heat of primary event mirror 6, so double-deck arrangement of mirrors structure, both solved light beam and assembled problem, and solved again the heat dissipation problem of LED light source 4.
LED light source 4 connects the both positive and negative polarity of driving power 8, because LED light source 4 of the present utility model is general between 5 ~ 7W, so relatively low to the requirement of driving power 8, but commercially available non-isolated constant-current driving power supply puts to enter Glass lamp base 2, so we redesign wiring board according to the space of Glass lamp base 2, its integrated package and peripheral component make variation in type selecting and arrangement, driving power 8 can be put in Glass lamp base 2, and have certain loosening leeway.
Primary event mirror 6 and secondary reflection mirror 7 are equipped with parabolic reflecting surface, and LED light source 4 is arranged on the focal plane of parabolic reflecting surface.In order to reduce beam angle, can reach halogen wick effect same, LED light source 4 have employed COB light source structure, and its source diameter is at Φ about 10mm, but for spot light or larger, so first we be configured with primary event mirror 6, this is a kind of reflective mirror of sphere, after such once light-distribution, again illumination is mapped on secondary reflection mirror 7, LED light source 4 is placed on parabolical focal plane, just can reflecting away light ray parallel, reach optically focused object.The colour temperature of LED light source 4 can be selected between 3000K ~ 6000K.
In order to solve the heat dissipation problem of LED light source 4, adopting the LED module of high voltage, low current COB structure, reducing himself caloric value, and fill heat conduction colloid 9 between Glass lamp base 2 and secondary reflection mirror 7, by conduction conduct heat away out in air.
As shown in Figure 2, diaphotoscope 1 can also adopt surface pressure to be shaped with the circular glass of hemispherical lamp pearl 10, and the light making it transmit is softer, and beam angle is larger.
The utility model has the following advantages:
1, adopt LED cold light source, when irradiating object, can not heat radiation be produced, the distortion to photographed object product, the problem such as rotten, aging can be stopped, especially for the article of textile, paper products and so on;
2, compare halogen spot light, the input power of LED light source is only the former 1/5 ~ 1/4, but has identical luminous flux and the brightness of Geng Gao.
3, driving power and light source core are combined in a lamp housing, the standard screw socket shot-light of this integration, original halogen wick or other types shot-light can be substituted very easily, and not need to do any variation on light fixture and circuit.
4, life-span (only depending on the components and parts life-span of driving power) of overlength and cost payout very nearly the same.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
