Abstract
The utility model discloses a reverse projection type LED stage spot light. The reverse projection type LED stage spot light comprises a spot light shell, a reflector with a reflection cover at the front end, and an LED assembly, wherein the reflector is installed in the spot light shell in the mode of sliding frontward and backward, and the LED assembly is fixed inside the spot light shell and arranged in front of the center of the reflection cover. Light illuminating the reflection cover from the LED assembly is emitted from the front end of the spot light shell after being reflected. According to the reverse projection type LED stage spot light, an LED is arranged in front, the reverse projection type spot light effect can be achieved through the reflector, the position, relative to the LED, of the reflector can be adjusted, and therefore light spot control and projection angle control can be achieved conveniently. Meanwhile, the emitting angle of a light source can be adjusted according to needs, the reflector can collect all the light emitted by the LED, and therefore the work efficiency of the spot light is improved.

Preferably, described adjustment assembly is a bolt, fixes one first support plate on bearing, and the first support plate is provided with a screwed hole; Fix one second support plate in lamp outer casing, the second support plate is provided with a through hole, described screwed hole and through hole are overlapping on the direction of slide rail motion, and described bolt wore screwed hole and bolt head is rotatably installed in through hole, and the afterbody of bolt extends the rear end of lamp outer casing; During swivel bolt, reflector slides on slide rail.
Preferably, the LED assembly comprises that LED is sticked on cooling base as the LED of light source and the cooling base for dispelling the heat, and cooling base is fixed on lamp outer casing by heat pipe.
Preferably, the rear portion in lamp outer casing is fixed with a radiator, and cooling base is fixed on radiator by heat pipe.
Technique scheme can be found out, because the utility model embodiment adopts LED preposition, realize anti-throwing type spotlight effect by reflector, and reflector is adjustable with respect to the position of LED, realize hot spot control and crevice projection angle that can be convenient be controlled, the lighting angle of light source can be adjusted as required, and reflector can be collected all light that LED sends, and makes the operating efficiency of spotlight get a promotion.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of existing LED stage projector;
Fig. 2 is the side structure schematic diagram of anti-throwing type LED stage projector in the utility model embodiment;
Fig. 3 is the positional structure schematic diagram of LED assembly and reflection shield in the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of anti-throwing type LED stage projector, as shown in Figures 2 and 3, comprise that lamp outer casing 1, front end are provided with reflector 2 and the LED assembly 3 of reflector 21, reflector 2 can be arranged in lamp outer casing 1 slidingly back and forth, LED assembly 3 is fixed in lamp outer casing 1 and is positioned at the place ahead at reflector 21 centers, and LED assembly 3 is penetrated by the front end of lamp outer casing 1 after reflection to reflector 21 irradiation light.
Adjusting assembly described in the utility model embodiment is a bolt 4, fixes one first support plate 23, the first support plates 23 on bearing 22 and is provided with a screwed hole; Interior one second support plate 12 of fixing of lamp outer casing 1, the second support plate 12 is provided with a through hole, described screwed hole and through hole are overlapping on the direction of slide rail 11 motions, described bolt 4 wore screwed hole and bolt head 41 is rotatably installed in through hole, the rear end that the afterbody 42 of bolt 4 extends lamp outer casing 1; During swivel bolt 4, reflector 2 slides on slide rail 11.
Certainly, in other embodiments, bolt is as adjusting assembly, and its head can be rotatably installed on the first support plate, and screwed hole is opened in to the rear end of lamp outer casing, can realize adjusting equally the effect of reflector locations.
Certainly, adjust in other embodiments assembly and also can adopt a card article directly to be fixed on bearing 22, in the rear end of lamp outer casing, offer corresponding bayonet socket, card article extends lamp outer casing by bayonet socket, pulls or promote the position adjustment that card article is realized reflector.
The LED assembly comprises that LED31 is sticked on cooling base 32 as the LED31 of light source and the cooling base 32 for dispelling the heat, and cooling base 32 is fixed on lamp outer casing by heat pipe 33.As a kind of improvement, in the utility model embodiment, the rear portion of lamp outer casing interior 1 is fixed with a radiator 5, cooling base 32 is fixed on radiator 5 by heat pipe 33, thereby increased the heat dispersion of LED assembly, cooling base adopts aluminium base, reduce the weight of whole light fixture, there is good radiating effect simultaneously.
