2results about How to "Reduce light attenuation" patented technology

The utility model relates to the technical field of LED display screens, in particular to an LED display screen with an auxiliary heat dissipation and ventilation structure, which comprises a mounting frame, a screen body is mounted in the mounting frame in an inserted manner, a back shell is arranged on one side, far away from the screen body, of the mounting frame in an inserted manner, an insertion opening is formed in the outer surface of one side of the mounting frame, and a ventilation hole is formed in the outer surface of the other side of the mounting frame. And heat dissipation ribs are clamped on the inner side of the mounting frame. According to the LED display screen with the auxiliary heat dissipation and ventilation structure, heat generated during operation of the screen body can be conducted to the outer surfaces of the heat dissipation ribs through the arranged heat dissipation silica gel pad so as to enlarge the heat dissipation area of the screen body, meanwhile, the screen body is inserted into the installation frame during installation, the heat dissipation ribs are clamped into one end of the installation frame, and the heat dissipation effect is improved. The screen body, the heat dissipation silica gel pad and the heat dissipation ribs can be installed and attached more easily and conveniently, and light attenuation, color cast and service life reduction caused by the fact that heat cannot be dissipated in time when the screen body runs for a long time can be reduced.

The utility model discloses a kind of automobile LED profile indicating lamp, by connecting piece, lamp shell, connecting sleeve, lampshade and several aluminium base plates in connecting sleeve, connecting sleeve is built-in for accommodating the positioning frame of aluminium base plate, heat conduction column is fixedly sleeved in lamp shell, heat conduction column extends to the enclosed space of several aluminium base plates, for the heat generated by aluminium base plate is exported, the top of the heat conduction column is fixedly installed with spoiler, so that automobile driving drives spoiler vibration, accelerates air convection auxiliary heat dissipation.The utility model cooperates in lamp body through heat dissipation fin, heat conduction column and spoiler, heat dissipation fin increases the surface area of lamp shell, heat conduction column cooperates with spoiler and accelerates air convection by vibration, the heat generated by aluminium base plate is rapidly dissipated, can make LED lamp bead operating temperature reduce, reduce light decay phenomenon, and improve lighting stability.
