The rear projection type LED suspended ceiling module comprises a keel and a panel, wherein a rear projection type LED light box is arranged in the middle of the panel; the rear projection type LED light box comprises a box body of which the bottom surface is open, an LED lamp arranged in the box body, and a scattering plate matched with the bottom surface of the box body; and the LED lamp is arranged in a cavity formed between the box body and the scattering plate. The original exposed structure of the LED lamp is improved into a built-in structure, so that the LED lamp is arranged in the light box, the illumination area and illumination uniformity of the LED suspended ceiling module are improved through condensing of the box body and scattering of the scattering plate, the illumination area of a single LED suspended ceiling module is improved, the number of the used LED suspended ceiling modules is reduced, the mounting and using costs are reduced, and the stimulus of the LED lamp light source on the eyes of the user can be effectively avoided.
Description
Technical field
The utility model relates to a kind of Integral ceiling equipment, is specifically related to a kind of back projection type LED suspended ceiling module.
Background technology
Existing LED suspended ceiling module is usually used in interior decoration, the some LED lamps that comprise panel and be connected to the panel below.The LED lamp is exposed to panel below, and light-emitting area down, makes light direct irradiation that the LED lamp sends on the ground.There is following defective in the LED suspended ceiling module of this structure: the light that the LED lamp sends is linearly propagated, but have directionality, make the LED suspended ceiling module can only guarantee the intensity of illumination of its peripheral lower zone, need to install many pack modules and realize that indoor illumination is even, raise the cost, also power consumption; When the user stood in LED lamp below, stronger light can cause user's eyes irriate.
The utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of illuminating area larger and uniform back projection type LED suspended ceiling module, and another purpose of the present utility model is to provide the soft and not dazzling LED suspended ceiling module of a kind of light.
The utility model is realized in the following manner: a kind of back projection type LED suspended ceiling module, the panel that comprises the keel that are arranged in parallel and be connected to the keel below, a back projection type LED lamp box is equipped with at described panel middle part, described back projection type LED lamp box comprises the casing of bottom surface opening, the astigmatism plate that is built in the LED lamp in described casing and mates with described tank floor, and described LED lamp is built in the cavity of described casing and astigmatism plate formation.The exposed structure that the LED lamp is original is improved to embedding structure, make the LED lamp be built in lamp box, and increase illuminating area and the illumination uniformity of LED suspended ceiling module by casing optically focused, astigmatism plate astigmatism, improve the illuminating area of single led suspended ceiling module, and reduce LED suspended ceiling module usage quantity with this, reduce installation, use cost, can also effectively avoid the LED lamp source to the stimulation of user's eyes.
As preferably, described LED lamp is equally distributed some groups, and its light-emitting area down.Improve intensity of illumination by many group LED lamps are set, and the light-emitting area of LED lamp down, makes the light that sends can pass through the astigmatism plate scattering, improves dispersion effect from the LED lamp.
As preferably, be provided with the opening that is complementary with described bottom half profile in the middle part of described panel.The bottom margin of described casing is connected with the opening coupling, effectively prevents the casing displacement, and convenient the installation also guaranteed the furred ceiling overall aesthetics.
As preferably, described wall box bottom inside is provided with flanging, described astigmatism plate by its overlapping edges on described flanging.Casing supports astigmatism plate by flanging, makes astigmatism plate edge and flanging match strap, prevents that the light that the LED lamp sends from directly injecting the interior space, improves the astigmatic rate of astigmatism plate.
As preferably, described casing is connected with adjacent keel by the connecting rod of being located on its two side.Connecting rod plays the effect of static housing, makes casing suspend and guarantees that its bottom surface flushes with panel.
As preferably, described connecting rod is fixed by securing member and described keel.Connect by securing member, simple in structure, both reduced costs, also easy disassembly improves installation effectiveness.
As preferably, described lattice plate both sides are provided with connector, described both sides connector spacing and the described adjacent keel pitch match corresponding with described keel coupling.Panel passes through the connector holding on described adjacent keel.
The beneficial effects of the utility model: the exposed structure that the LED lamp is original is improved to the structure that is built in lamp box, the astigmatism of astigmatism plate is used for increasing illuminating area and the illumination uniformity of LED suspended ceiling module bottom lamp box, reduce LED suspended ceiling module usage quantity with this, reduce installation, use cost, also effectively avoid the LED lamp source to the stimulation of user's eyes.

The specific embodiment
Below in conjunction with specification drawings and specific embodiments, substantive distinguishing features of the present utility model is further described.
A kind of back projection type LED suspended ceiling module as shown in Figure 1, formed by the keel 1 that are arranged in parallel, the back projection type LED lamp box 3 that is connected to the panel 2 of keel 1 belows and is arranged on panel 2 middle parts, described back projection type LED lamp box 3 comprise the bottom surface opening casing 4, be built in described casing 4 LED lamp 5 and with the astigmatism plate 6 of described casing 4 bottom surfaces couplings, described LED lamp 5 is built in the cavity that described casing 4 and astigmatism plate 6 form; Described LED lamp 5 is equally distributed some groups, and its light-emitting area down; Described panel 2 middle parts are provided with the opening that is complementary with described casing 4 bottom profile; Described casing 4 sidewall bottom inside are provided with flanging 7, and described astigmatism plate 6 is passed through its overlapping edges on described flanging 7; Described casing 4 is connected with adjacent keel 1 by the connecting rod 8 of being located on its two side; Described connecting rod 8 is fixing with described keel 1 by securing member 9; Described lattice plate both sides are provided with connector 10, described both sides connector 10 spacings and described adjacent keel 1 pitch match corresponding with described keel 1 coupling.
In concrete operations, casing 4 is fixed on keel 1 by connecting rod 8, and the bottom of casing 4 flushes and is suspended at (as shown in Figure 2) in panel 2.
