The metal bracket is an H-shaped metal bracket, notches for the installation of the circuit board are respectively formed on two upper and lower sides of the H-shaped metal bracket, and the light source component is fixedly installed on the circuit board. The double-sided backlight module provided by the utility model has excellent heat and electricity conductivities via directly welding the light source component onto the metal circuit board. A metal material external member is hermetically encapsulated with epoxy resin, so that the degree of protection reaches IP68, the performance of aging resistance, UV resistance, moisture resistance and damp resistance are good, and the adaptive capacity to environment is strong. The length can be selected by cutting randomly, and the unit length is 84mm. The installation is convenient, rapid and beautiful. The double-sided backlight module is applied to high, bright and remote backlight for top-grade high-rise buildings, contour accentuation, decoration and interspersion for wall surfaces, doors and windows, and so on. The effects of gradual changing, jumping and chasing can be achieved after a control system is equipped. Changing or static captions, patterns, cartoons, images and so on can be formed by dense arrangement. The asynchronous control or the synchronous control can be realized.
Description
Technical field
The utility model relates to module backlight, more particularly, relates to a kind of two-sided 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, a kind of two-sided module backlight is provided, comprise metallic support, circuit substrate and light source assembly, described metallic support is " H " shape metallic support, the both sides up and down of described " H " shape metallic support form the fluting of installing for described circuit substrate respectively, and described light source assembly is fixedly mounted on the described circuit substrate.
In two-sided module backlight 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 two-sided module backlight described in the utility model, described light source assembly is two groups, and described circuit substrate is two, and described circuit substrate is installed in respectively in the described fluting of both sides up and down of described " H " shape metallic support; Described end cap is two groups and is plugged in each described fluting two ends respectively.
In two-sided module backlight 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 two-sided module backlight described in the utility model, described circuit substrate is the metallic circuit substrate.
In two-sided module backlight described in the utility model, described metallic circuit substrate is aluminium alloy electric base board or copper base.
Implement two-sided module backlight of the present utility model, 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.
