Abstract
The utility model relates to an LED flat light box which comprises a light box shell, an LED light source, a light reflecting membrane, a light guiding plate, a light transmitting panel and an advertisement picture; the light reflecting membrane, the light guiding plate and the advertisement picture are sequentially arranged; the LED light source is arranged on the periphery of the light guiding panel; and the LED light source, the light reflecting membrane, the light guiding plate, the light transmitting panel and the advertisement picture are arranged in the light box shell. The LED light source irradiates from the side of the light guiding plate so that light rays are multiply refracted in the light guiding plate and the whole light guiding plate roundly gives out lights; and therefore, the irradiating angle of the light fixture is increased and simultaneously the sent light rays are uniform and soft.
Description
Technical field
The utility model relates to light fixture, relates in particular to a kind of dull and stereotyped lamp box of LED that is used for decorative lighting.
Background technology
Traditional advertising lamp box generally adopts ordinary lamp and lanterns such as Metal halogen lamp, daylight lamp as light emitting source, because conventional lamp is to the limitation of control optical tech, a common advertising lamp box needs a plurality of light fixtures just can reach radiation response, and the uniformity coefficient of light neither be very desirable, easily periphery produced light pollution.
The led light source of Chu Xianing is applied in the advertising lamp box subsequently, however existing LED advertising lamp box because its uneven illumination is even, irradiating angle is little, light is evenly soft inadequately, radiation response integral body is relatively poor, and the heat that led light source produces at work can not in time get rid of, and lamp life is impacted.
The utility model content
The utility model provides a kind of LED dull and stereotyped lamp box at the above-mentioned defective of prior art, with the irradiating angle of raising light fixture, and makes the light that sends evenly soft.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The dull and stereotyped lamp box of a kind of LED comprises lamp box shell, led light source, reflective membrane, light guide plate, light-passing board, advertisement picture; Reflective membrane, light guide plate, advertisement picture, light-passing board are arranged in order, and led light source is located at the light guide plate periphery; Led light source, reflective membrane, light guide plate, light-passing board, advertisement picture are installed in the lamp box shell.
Preferably, the aluminium base of described led light source is close to the metal lamp house shell, and scribbles heat-conducting silicone grease between the two.
Preferably, described led light source is made up of the LED of multiple color, and the LED of this multiple color is connected with lamp dimmer respectively.
As can be seen from the above technical solutions, the utility model led light source makes light produce repeatedly refraction in light guide plate from the light guide plate side-irradiation, makes whole light guide plate luminous comprehensively, has increased the irradiating angle of light fixture, makes the light that sends evenly soft simultaneously.Further, the utility model adopts the metal lamp house shell, and after the aluminium base of led light source and lamp box shell fitted tightly, the metal lamp house shell also as radiator heat-dissipation, had improved radiating efficiency as lamp box the time.The LED of multiple color can realize flowing water, multiple fantasy dynamic effect such as flicker alternately under the control of lamp dimmer.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
Shown in accompanying drawing, the dull and stereotyped lamp box of the utility model LED comprises lamp box shell 1, led light source 2, reflective membrane 3, light guide plate 4, light-passing board 5, advertisement picture 6; Reflective membrane 3, light guide plate 4, advertisement picture 6, light-passing board 5 are arranged in order, and led light source 2 is located at the light guide plate periphery; Led light source 2, reflective membrane 3, light guide plate 4, light-passing board 5, advertisement picture 6 are installed in the lamp box shell 1.
As preferred implementation of the present utility model, the aluminium base of led light source 2 is close to metal lamp house shell 1, and scribbles heat-conducting silicone grease between the two, and the lamp box shell of metal material can be made heating radiator and use the raising thermal efficiency.
As preferred implementation of the present utility model, described led light source 2 is made up of the LED of multiple color, and the LED of this multiple color is connected with lamp dimmer respectively, can realize bright and colourful dynamic picture.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
