Abstract
The utility model discloses a reversed light gathering LED (light-emitting diode) lamp, which comprises an LED illuminant, a reflector and a radiator and is characterized by further comprising a top pole. The top pole is arranged at the top of the reflector and connected with the reflector. At least two fixed rods are fixed on the top pole in a direction of a reflector opening. The radiator is fixed at the other end of the fixed rod away from the top pole, a fitting surface facing the top pole is arranged on the radiator and provided with the LED illuminant, and a lighting surface of the LED illuminant faces towards the top pole. By means of the method, the LED illuminant of the LED lamp faces the top pole, namely the bottom of the reflector, all the light emitting from the LED reaches a reflecting surface first before emitting from a light emitting opening. All emitted light has been processed twice through a surface of the reflector, users can not view the LED illuminant directly, thereby avoiding glare produced by the LED illuminant to a maximum degree, improving safety and comfortableness in usage.
Description
Technical field
The utility model relates to a kind of lighting device, specifically is a kind of reverse optically focused LED lamp.
Background technology
Led light source is used for illumination to begin to popularize gradually.The advantage of its high light efficiency, high-color rendering and safe spectrum makes the ligthing paraphernalia in each field begin to use led light source gradually.
Led light source is according to its luminous characteristics, and its surface brightness is quite strong, if naked eyes are looked at its light-emitting area straight; usually the situation that has discomfort even anergy takes place, and therefore, led light source is when applying to ligthing paraphernalia; can produce so dazzle, the sensory effects that influence is used works the mischief to health.
In the LED light fixture, output does not cause very big decay to the fitting structure that how to guarantee the LED lamp to light, and the direct projection that avoid the high light intensity of led light source is arranged simultaneously, is a urgent problem.
The utility model content
At the too strong problem of LED dazzle, the utility model proposes a kind of reverse optically focused LED lamp, its technical scheme is as follows:
A kind of reverse optically focused LED lamp comprises led light source, reflector, radiator, and it also comprises a fore-set and plurality of fixed bar: wherein fore-set places described reflector top, is connected with reflector; This fore-set is being fixed at least two fixed bars towards described reflector opening direction; Described fixed bar has an installed surface towards fore-set away from the fixing described radiator of an end of fore-set on this radiator, fixing described led light source on it, and this led light source exiting surface is towards described fore-set.
Preferred person as the technical program, can do following improvement:
Described reflector slidably is socketed on described fore-set, and the relative position of reflector and fore-set is adjustable;
Described reflector have at the described fore-set of socket place can fastening described fore-set retaining mechanism, this retaining mechanism can be fasteners commonly used such as trip bolt, the collar;
Described radiator has the leader towards described reflector opening direction pointer;
Described fixed leg can have at least one to be hollow person, the power line of its interior described led light source of cross-under of the fixed leg of this hollow;
Described reflector can have the interior reflective surface of compound conic section bus.
The beneficial effect that the technical program has is:
1.LED light source is towards fore-set, that is to say the bottom of reflector, all light that sent by LED all arrive the reflector reflecting surface earlier just from the outgoing of reflector light-emitting window, all output light of user have all been passed through the reflector surface after-treatment, and can not direct view led light source, therefore, the dazzle that is produced by led light source is avoided to the utmost.
2. the reflector slip cap is connected to fore-set, makes reflector and fore-set relative axial position to adjust, thereby has adjusted the distance of reflector and led light source, makes that the light beam of final reflector output is adjustable, and its range of exposures is also adjustable.
3. the reflecting surface of compound conic section bus makes the sliding reflection device adjust light output can satisfy different beam shapes, comprises and disperses the requirement different with optically focused.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the utility model one embodiment schematic diagram;
Fig. 2 is that Fig. 1 assembles the schematic diagram that finishes.
The specific embodiment
As shown in Figure 1, the utility model one embodiment schematic diagram.Rotational symmetric reflector 2 is socketed on fore-set 1 lower end, can vertically slide up and down with respect to fore-set 1; Fixed leg 3 has two, and both parallel and upper ends are anchored on the bottom of fore-set.
The fastening radiator 4 in fixed leg 3 bottoms, led light source 5 is settled as installed surface in the last plane of radiator 4, and plane is perpendicular to reflector 2 central shafts on this; Has Heat Conduction Material between radiator 4 and the led light source; Below radiator 4, also has leader 6.
Fig. 2 is the stereogram of roll-outing, led light source 5 is positioned at reflector 2 inside together with radiator 4, because the directionality luminous characteristics of led light source, its exiting surface has not had light output in the beam angle scope greater than 180 °, thereby can't look at the light-emitting window of led light source 5 straight from the outside, avoided the dazzle that causes because of the LED direct projection.This state can hang fore-set 1 to get up to use; If adopt telescopic suspension arrangement, can also regulate the height of whole lamp by handle 6.In actual use, because the internal reflection surface of reflector 2 has the bus feature of compound conic section, the light source that is positioned at its inside center axle diverse location can obtain the different effects that converges or disperse; By the vertical position (50 millimeter adjustable range) of accommodation reflex device 1 on fore-set 1, the light output that can obtain different optically focused and/or disperse, light output is that the reflector Way out is downward.
Claims (6)
1. a reverse optically focused LED lamp comprises led light source, reflector, radiator, it is characterized in that it also comprises:
One fore-set places described reflector top, is connected with reflector; This fore-set is being fixed at least two fixed bars towards described reflector opening direction;
Described fixed bar has an installed surface towards fore-set away from the fixing described radiator of an end of fore-set on this radiator, fixing described led light source on it, and this led light source exiting surface is towards described fore-set.
2. a kind of according to claim 1 reverse optically focused LED lamp is characterized in that described reflector slip cap is connected to described fore-set.
