Abstract
The utility model relates to a four-sided backlight module, comprising a metal support, circuit substrates and light source components, wherein, the metal support is a cylindrical metal support the side surfaces of which are uniformly provided with four notches for mounting the circuit substrates; and the light source components are fixed on the circuit substrates. The four-sided backlight module directly welds the light source components to the metal circuit substrates, thereby having excellent thermal conductivity and electric conductivity. Metal material external members and epoxide resin encapsulate the four-sided backlight module in fully enclosed mode, thereby the protection class reaches IP 68, and the four-sided backlight module has age resistance, ultraviolet resistance, good humidity resistance and moisture resistance, and strong adaptive capacity to environment. The length of the four-sided backlight module can be selected freely (the unit length is 84 mm). The four-sided backlight module is beautiful and convenient and quick to mount, is suitable for high brightness remote backlight lighting of advanced high-rise buildings, edge enhancement of profiles, and decoration and enhancement of wall surfaces and doors and windows, etc., and can have the effect of gradual change, jumping and chasing after the configuration of a control system. Four-sided backlight modules are densely arranged to generate dynamic or static captions, patterns, animations and pictures, etc., and can realize asynchronous and synchronous control.
Description
Technical field
The utility model relates to module backlight, more particularly, relates to a kind of four sides module backlight.
Background technology
More existing modules backlight particularly are applied to the illuminating module on the occasions such as advertisement lamp decoration, advertisement word, are mostly to adopt neon light as light source.Yet there is short, shortcoming such as caloric value is big of life-span in neon light, and the cycle of its maintenance is short, workload is big, and the light emitting control difficulty of neon light, can't adaption demand.Along with the development of led light source, in module backlight led light source gradually substituted the neon light light source.Yet in the module backlight of existing LED, usually the low-power LED light-emitting diode chip for backlight unit is welded on the circuit substrate of plastics like this, the heat-conductivity conducting poor-performing, brightness is low, and the life-span is short.
The utility model content
The technical problems to be solved in the utility model is, above-mentioned defective at prior art, provide a kind of four sides module backlight, comprise metallic support, circuit substrate and light source assembly, described metallic support is the cylindrical metal support, the side of described cylindrical metal support evenly is provided with four flutings installing for described circuit substrate, and described light source assembly is fixedly mounted on the described circuit substrate.
In the module backlight of four sides described in the utility model, also comprise: at least one group of end cap that is inserted in described metallic support two ends; Described end cap is arranged on the both sides of described light source assembly, and is provided with the packaging plastic that the three is bonded into an integral body between described light source assembly, end cap and the metallic support.
In the module backlight of four sides described in the utility model, described light source assembly is four groups, and described circuit substrate is four, and described circuit substrate is installed in respectively in four described flutings of side of described cylindrical metal support; Described end cap is two groups and is plugged in each described fluting two ends respectively.
In the module backlight of four sides described in the utility model, described light source assembly comprises LED lamp group and is connected the lead that power supply is introduced at described circuit substrate two ends; Be respectively equipped with one group of gliding movement targeting structure that is used to install described LED lamp group between the sidewall of each described fluting and each the described end cap.
In the module backlight of four sides described in the utility model, described circuit substrate is the metallic circuit substrate.
In the module backlight of four sides described in the utility model, described metallic circuit substrate is aluminium alloy electric base board or copper base.
Implement four sides of the present utility model module backlight, have following beneficial effect: by light source assembly being welded direct on the metallic circuit substrate excellent heat-conductivity conducting performance.The totally-enclosed embedding of metal material external member and epoxy resin, degree of protection reaches IP68, and anti-aging, anti-ultraviolet, protection against the tide, moisture-proof characteristic are good, and adaptive capacity to environment is strong.Length can be cut out choosing, (unit length 84mm) arbitrarily.Easy for installation, quick, attractive in appearance.Be applicable to that the highlighted long-range back lighting, profile crisperding of high-grade high-rise building construction and metope door and window decorate and intersperse etc., the effect of can produce gradual change, saltus step after the configuration control system, chasing.Dense arrangement can produce change or static captions, pattern, animation and image etc., can realize asynchronous and Synchronization Control.
