Abstract
The utility model relates to a light-emitting diode (LED) module adjustable in luminance. An existing LED module has the problems of being poor in luminance uniformity, large in light failure, and small in selection range in the utilization process. The LED module adjustable in the luminance comprises a shell, paster LED lights, and a control circuit. The shell is provided with LED holes, and the paster LED lights are arranged in the corresponding LED holes and driven by the control circuit. The control circuit is further connected with an adjustable resistor used to adjust the luminance of the paster LED lights. The LED module adjustable in the luminance is suitable for lighting of various indoor lighting labels and display cabinets and has the advantages of being uniform in luminance, large in selection range, long in service life, little in light failure, and good in color displaying performance.
Description
Technical field
The utility model belongs to the LED lighting technical field, relates to a kind of brightness adjustable LED module.
Background technology
The LED module of usefulness all is that brightness is fixing uncontrollable in the market, and this can cause energy waste for the different application place.Existing LED module in use exists brightness uniformity poor simultaneously, the large and range of choice minor issue of light decay.
Summary of the invention
The utility model provides a kind of brightness adjustable LED module for the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model comprises shell, paster LED lamp, control circuit.Have the LED hole on the shell, the paster LED lamp is arranged in the corresponding LED hole, and described paster LED lamp is driven by control circuit, and described control circuit also is connected with to regulate the adjustable resistance of paster LED lamp brightness.
The beneficial effects of the utility model are: the utility model is applicable to various indoor luminous marks and showcase illumination.It is even to the utlity model has brightness, and range of choice is large, long service life, and light decay is little, the good advantage of colour rendering.
Description of drawings
Fig. 1 is the utility model installation diagram;
Fig. 2 is that Fig. 1 assembles rear schematic diagram;
Fig. 3 is the control circuit circuit theory diagrams.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises shell 2, paster LED lamp 4, control circuit.Single face pcb plate 3 is adopted in the loam cake perforate of shell, module, and top layer is light source, and bottom is control circuit, and wire 5 is connected on the pcb board.Then put glue, shell and base 1 are closed by buckle 8 again, namely play protection paster LED lamp and can reach water-proof function again, be furnished with adjustable potentiometer 7, constant current control chip 6 at an end of single face pcb plate 3, wherein constant current control chip 6 models are BCR402U.
As shown in figures 1 and 3, adjustable potentiometer RX one termination 12v power supply, No. 6 pins of another termination constant current control chip (BCR402U), No. 4 pins of constant current control chip (BCR402U) connect the 12v power supply, No. 1 pin ground connection, 2,3,5 pins connect respectively the paster LED input, the LED output head grounding.After external AC/DC power supply energising, provide the 12v dc source to the adjustable module of brightness, by regulator potentiometer RX, the regulation output electric current, so that module brightness change, thereby it is even to reach brightness.
