Abstract

An LED (Light Emitting Diode) backlight source mainly consists of an upper-side lighting plate, LED light sources, a base frame, and a lower-side light guiding plate and a rubber frame fixed on the base frame. A plurality of LED light sources are arranged at the periphery of an inner ring of the base frame by a PCB (Printed Circuit Board), and the light of the LED light sources irradiates the lower-side light guiding plate through the circumference; the upper-side light emitting plate is arranged on the base frame, and a cover plate according to needs is arranged between the upper-side lighting plate and the lower-side lighting plate; the rubber frame is used for fastening the upper-side lighting plate and the cover plate on the base frame by screws; and as the plurality of LED lighting sources are arranged at the periphery of the inner ring of the base frame, and the LED lighting sources at the periphery of the inner ring are utilized for irradiating the lower-side light guiding plate and the upper-side lighting plate, the LED backlight source has the advantages that the lighting source radiating effect is obvious, the lighting strength is strong, the service life of the LED light sources is long, the efficiency is high, the power consumption is low and the like.

Description

The LED-backlit source

Technical field

The utility model relates to the electric light source technology field, and what be specifically related to is the LED-backlit source that a kind of saves energy is economized consumption.

Background technology

Backlight has been widely used in the outdoor advertising marking field, and in order to increase effect, people often adopt the daylight lamp stand as backlight, and its shortcoming is: caloric value is high, and power consumption is big, and service life is short.

Summary of the invention

The purpose of the utility model is the deficiency that solves prior art, and LED-backlit source a kind of simple in structure, low in energy consumption, long service life is provided.

The utility model is realized through following technical scheme: the LED-backlit source, mainly form by upside luminous plaque, led light source, pony sill, the downside LGP and the glue frame that are fixed on the pony sill.

The said outer surface that is fixed on the following survey LGP below the pony sill is a flour milling.

Led light source quantity can be made as several, and several led light sources are located at through the pcb board arrangement around the inner ring of pony sill, and its light is surveyed on the LGP through being radiated at down all around.

The upside luminous plaque be located at pony sill above, and upside luminous plaque and survey between the LGP down and can establish a cover plate as required.

Said glue frame is fastened on upside luminous plaque and cover plate above the pony sill through screw.

The beneficial effect of the utility model embodies and is: through around the inner ring of pony sill, being provided with several LED light emitting sources; Utilizing inner ring LED light emitting source all around to be radiated at down surveys on LGP and the upside luminous plaque; Thereby it is remarkable to make light source disperse effect; Intensity of illumination is strong, and advantage such as led light source long service life, efficient be high, low in energy consumption.

Description of drawings

Below in conjunction with accompanying drawing the utility model is carried out detailed explanation.

Fig. 1 is the utility model STRUCTURE DECOMPOSITION sketch map.

Fig. 2 is the A place enlarged diagram of Fig. 1.

The specific embodiment

Like Fig. 1 and shown in Figure 2, the LED-backlit source mainly is made up of upside luminous plaque 2, led light source 3, pony sill 4, the downside LGP 5 and the glue frame 1 that are fixed on the pony sill 4.

The said outer surface that is fixed on the following survey LGP 5 below the pony sill 4 is a flour milling.

Several led light sources 3 are through around the evenly distributed inner ring that is located at pony sill 4 of pcb board 8, its light through around be radiated at down on the survey LGP 5.

Upside luminous plaque 2 be located at pony sill 4 above, and upside luminous plaque 2 and survey between the LGP 5 down and can establish a cover plate 9 as required.

Said glue frame 1 is fastened on upside luminous plaque 2 and cover plate 9 above the pony sill 4 through screw.

By extracting power supply cord 7 on the pcb board 8, also be provided with LED driving power 6 on the said power line 7.

When using the utility model backlight; Energized; Drive through LED driving power 6 and to make several led light sources that are evenly arranged in around pony sill 4 inner rings simultaneously luminous, and be radiated at upside luminous plaque 2 and survey on the LGP 5 down, thereby reach purpose the light source diffusion.
