Description
Technical field
The utility model relates to a kind of light-source system of lamp box, relates in particular to a kind of LED lamphouse light source system.
Background technology
The light source of traditional advertising lamp box adopts several fluorescent tubes that be arranged in parallel more, and as the improvement to conventional lightbank, the existing existing LED of employing occurs as the lamp box of light source.
Luminous different with 360 degree of fluorescent tube, LED is luminous to have an effective irradiating angle, generally directly over about illumination in each 45 degree (totally 90 degree) scope the strongest, it is just very weak to surpass 120 illumination of spending in the scopes of 160 degree, but all has illumination in theory in 180 degree scopes.
Existing LED lamphouse light source system is that LED is arranged on the backboard side, thus, effective illumination that send in the front of every LEDs can directly effectively project to be showed on the picture, show on the picture but the light outside the effective illumination range that side direction is sent then is difficult to directly project, also be difficult to transmit the effective sunlight that formation can be perceived by the human eye outside the lamp box on the picture even project.This is with regard to the very big brightness that has reduced lamp box integral body.
Therefore,, can only increase the luminous power of LED, cause energy consumption to increase in order to improve brightness.Yet, increase the result of luminous power, not only can cause energy consumption to increase, and can make that the brightness of effective illumination that the LED forward sends is bigger, and because there is a determining deviation each other in LED, this will cause the lamp box picture the discontinuous or uneven phenomenon of light to occur, promptly has the light and shade contrast between led light source, influences the bandwagon effect of lamp box picture.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of LED lamphouse light source system, can significantly save the energy, and improves the uniformity and the illuminance of illumination on the lamp box display surface.
For achieving the above object, the utility model provides a kind of LED lamphouse light source system, comprise backboard, at least one side of described backboard is provided with a plurality of LED groups, and each LED group comprises at least one LED, is used for shining to the picture exhibition direction, described backboard comprises a plurality of reflecting units on the side, described reflecting unit has the recessed spatial accommodation of opening towards the picture exhibition direction, and at least a portion of the inner surface of described spatial accommodation is a reflective surface, and described LED is arranged in the described spatial accommodation.
After the utility model will be reflected through collection by the light that the LED side direction is sent, project uniformly on the display screen orientation of lamp box, thereby both can increase the illuminance of lamp box light plane, can make the lighting effect of showing on the picture more even again, and can further reduce the volume of lamp box, improve the efficiency of light energy utilization and energy savings significantly.

The specific embodiment
With reference to the accompanying drawings the utility model is elaborated.
See figures.1.and.2 and be an embodiment of the present utility model.The light-source system of LED lamp box generally comprises the backboard (not shown), and adopt LED as light source, at least one side of described backboard is provided with a plurality of LED groups, each LED group comprises at least one LED 2, be used for shining to the picture exhibition direction, in addition, also comprise a plurality of reflecting units 1 on the described backboard side, described reflecting unit has the recessed spatial accommodation of opening towards the picture exhibition direction, at least a portion of the inner surface of described spatial accommodation is a reflective surface, and described LED 2 is arranged in the described spatial accommodation.The reflection of the inner surface by these recessed spatial accommodations can well be collected the lateral light of LED and concentrated reflection to display screen orientation.
In the present embodiment, adopting effective lighting angle is the LED 2 of 160 degree, in other embodiments, also can adopt the LED of other lighting angle as required, for example 120 degree.(also can be that spaced apart has certain intervals) inverted tetragonous cone table shape that reflecting unit 1 can interconnect for a plurality of peristomes edge.The inner surface of the reflecting unit of tetragonous cone table shape, promptly medial surface and bottom surface can be reflective surface, and LED is arranged on the bottom surface or side of described reflecting unit symmetrically, and in this example, LED 2 is arranged on the symmetry axis of reflecting unit inner bottom surface, as shown in Figure 2.
Described reflecting unit can be to be made of original paper independently, be arranged at the place ahead, described backboard side, for example, described reflecting unit can comprise a hollow pipe type (for example infundibulate or bowl-type) device, form the madial wall of described reflecting unit, one side of this hollow pipe type device is connected with described backboard side, covers on the backboard side, defines the inner bottom surface of described reflecting unit; Described reflecting unit also can be the following concave space that is integrally formed at the backboard side, and the utility model does not limit this.
