Abstract
The utility model discloses a lamp strip protective cover on LED display screen, which comprises LED display screen lamp strips, a P C B lamp board and a protective cover, wherein the protective cover is located above the LED display screen lamp strips. The utility model can shield sunshine and rain water through adding the protective cover above the LED display screen lamp strips, prevents sunshine from directly irradiating the lamp strips, and prevents rain water from directly contacting with LED lamps, obstructs heat energy from being transmitted to the lamp strips, and keeps excellent heat dissipation of the lamp strips. The lamp strip protective cover can well protect light-emitting components on the display screen lamp strips when an LED display screen is used outside, and does not affect the working stability by heat energy generated by water and irradiation of ultraviolet rays or sunshine.
Description
Technical field
The utility model relates to the LED display technical field, relates in particular to lamp bar protective cover on a kind of LED display.
Background technology
LED display can be issued various information such as literal, pattern, video demonstration as a kind of instrument that releases news.LED display is that the lattice module or the display pixel cells that adopt light emitting diode to constitute are formed.This information display screen is used for the public place, exploitation, comprise be used in indoor or outdoor.When LED display uses out of doors; dustproof, waterproof, antiultraviolet and prevent display screen overheated be a very important link; if display screen is drenched with rain, long-term ultraviolet ray is shone; when the sunlight direct projection produces very big heat etc.; the housing of light-emitting component and carrying thereof is not taked suitable safeguard measure; overheated and the ultraviolet irradiation of light-emitting component is damaged, or pile up dust behind the trickle, will influence the quality of the light efficiency and the display screen of light-emitting component.
Existing LED display all is to adopt directly from the face shield of lamp bar section bar or lamp bar front directly to increase to come sunshade and keep off the rain.But this mode of keeping off the rain is thorough inadequately.In use still may there be rainwater to be flushed in above the light-emitting component accumulation dust that afterwards will be a large amount of.And directly the drawback of sunshade is a lamp bar when directly contact with sunlight, can produce the flight data recorder endothermic effect, causes lamp bar temperature to raise, and lamp bar internal heat discharges slowly, causes that easily light emitting diode damages, the service life of reduction LED demonstration.
The utility model content
The technical problems to be solved in the utility model provides lamp bar protective cover on a kind of LED display.
For solving the problems of the technologies described above, the purpose of this utility model is achieved through the following technical solutions.
Lamp bar protective cover on a kind of LED display comprises: LED display lamp bar, the PCB lamp plate also comprises: protective cover, described protective cover are positioned at LED display lamp bar top.
Wherein, leave the ventilation and heat gap between described LED display lamp bar and the protective cover.
Wherein, be filled with heat-barrier material between described LED display lamp bar and the protective cover.
Wherein, described protective cover adopts heat-barrier material to make.
Wherein, be interval with several light-emitting components on the described PCB lamp plate
The beneficial effects of the utility model are as follows:
The utility model is by fixing a protective cover on LED display lamp bar, be used for keeping the sun off and rainwater, prevent the sunlight direct irradiation on the lamp bar, and prevent that rainwater from directly contacting with the LED lamp, ventilation gap plays the heat-blocking action block heat and is transmitted on the lamp bar, and can allow the lamp bar better dispel the heat.Make when LED display uses out of doors, can be good at protecting the light-emitting component on the display screen lamp bar, be unlikely to the stability of its work of heat effects of being produced by water, ultraviolet ray and sunlight direct projection.
Description of drawings
Fig. 1 is the utility model LED display lamp bar sectional view;
Fig. 2 is the utility model LED display lamp bar structure chart.
The specific embodiment
For ease of the utility model is further understood, now reach specific embodiment in conjunction with the accompanying drawings the utility model is described in detail.
See also shown in Fig. 1,2, comprising: protective cover 1, LED display lamp bar 2, PCB lamp plate 3;
Protective cover 1 is positioned at LED display lamp bar 2 tops, and leaves certain ventilation gap between LED display lamp bar 2 and protective cover 1; Be used for keeping the sun off and rainwater, prevent the sunlight direct irradiation on the lamp bar, and prevent that rainwater from directly contacting with the LED lamp, ventilation gap plays the heat-blocking action block heat and is transmitted on the lamp bar, and can allow the lamp bar better dispel the heat.Make when LED display uses out of doors, can be good at protecting the light-emitting component on the display screen lamp bar, be unlikely to the stability of its work of heat effects of being produced by water, ultraviolet ray and sunlight direct projection.
PCB lamp plate 3 is installed on the LED display lamp bar 2.
Wherein, be interval with several light-emitting components on the PCB lamp plate.
The utility model is by increasing by a protective cover on LED display lamp bar, be used for keeping the sun off and rainwater, prevent the sunlight direct irradiation on the lamp bar, and prevent that rainwater from directly contacting with the LED lamp, ventilation gap plays the heat-blocking action block heat and is transmitted on the lamp bar, and can allow the lamp bar better dispel the heat.Make when LED display uses out of doors, can be good at protecting the light-emitting component on the display screen lamp bar, be unlikely to the stability of its work of heat effects of being produced by water, ultraviolet ray and sunlight direct projection.
More than lamp bar protective cover on a kind of LED display provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
