Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing and example.

[0018] Such as Figure 1-2 As shown, the present invention provides a light-changing LED roller shutter light, which includes a power cord 1 and several light bars connected by the power cord 1. The light bar is an aluminum substrate 2, and a plurality of light-emitting groups 3 are installed on the aluminum substrate 2. , each light-emitting group 3 is connected in series, and more than two LED lamp beads 4 are arranged in the light-emitting group 3, and the LED lamp beads 4 are connected in parallel with each other. The low-voltage output of the power supply is connected with a dimming controller 9, and the dimming controller 9 is electrically connected with the light-emitting group. The light bar adopts the aluminum substrate 2 with high heat dissipation, which can accelerate the heat dissipation of the LED lamp bead 4 and effectively prolong the service lif...

Abstract

The invention discloses a lamplight gradient LED roller shutter lamp. The LED roller shutter lamp comprises a power line and several lamp bars connected through the power line, the lamp bars are aluminum substrates, each aluminum substrate is provided with multiple illuminating sets, all the illuminating sets are in series connection, each illuminating set is internally provided with two or more LED lamp beads, the LED lamp beads are in mutual parallel connection, a voltage stabilizing power source connected with electric supply is arranged on the power line, and a light-adjusting controller is connected to the low-voltage output end of the voltage stabilizing power source, and is electrically connected with the illuminating sets. Regarding the electric supply, when the lamp is turned on, the brightness of the LED lamp beads is gradually improved through the light-adjusting controller; before the lamp is turned off, the brightness of the LED lamp beads is gradually lowered through the light-adjusting controller, and instantaneous brightness and extinguishment are avoided, so that the human eyes have an adaption process. Meanwhile, two or more LED lamp beads are in parallel connection to jointly serve as one illuminating set, and in this way, the work stability of the roller shutter lamp can be greatly improved.

Description

technical field [0001] The present invention relates to an LED roller shutter lamp, in particular to a light gradient LED roller shutter lamp. Background technique [0002] The roller shutter light is a kind of LED lamp used in the interior lighting of the advertising light box. It is mainly connected in parallel by LED light strips with connecting wires. In the actual use of the roller shutter light, generally the light is turned on when it is turned on, and it is turned off when the light is turned off. Moreover, the current changes greatly at the moment of switching on and off, which will cause an impact on the LED lamp beads. Once one of the LED lamp beads directly connected in series is damaged, the entire LED light bar will not light up, forming a dark side in the advertising light box and unable to display advertisements. the best publicity effect. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present ...
