Abstract
The utility model provides an LED grid backlight which comprises circuit boards provided with LEDs and double electric wires, wherein the circuit boards are steadily buckled in a plastic cover body, and the plastic cover body is composed of upper covers arranged on the surfaces of the circuit boards and lower covers arranged on the bottom surfaces of the circuit boards. According to the LED grid backlight, the circuit boards can be designed to be constant-voltage circuit boards or constant-current circuit boards according to market demands, multiple circuit boards can be connected through the double electric wires arranged on the circuit boards to achieve the breakover of the multiple circuit boards, the LEDs can be segmented with three as a group or one by one, flexible and convenient replacement, installation, adjustment and maintenance of a single circuit board can also be achieved, and the entire body is fixed through the cover body in a buckled mode. Therefore, the LED grid backlight has the advantages of being energy-saving, environment-friendly, reliable, durable, low in using cost, scientific and reliable in structure, low in energy consumption, convenient to splice, flexible in splicing, uniform in luminance, and broad in market prospect.
Description
Technical field:
The utility model relates to the lighting apparatus field, refers to a kind of easy operating especially, LED grid backlight easy to use.
Background technology:
LED (light emitting diode) compares with traditional cold-cathode tube backlight as a kind of environmental protection, energy-conservation new type light source, and the LED-backlit source has characteristics such as low-power consumption, lower calorific value, brightness height, life-span be long.
But having limited the reason that the penetration and promotion of LED-backlit source comes mainly is: the one, and complex structure directly raised manufacturing cost; The 2nd, the illumination utilization rate is low.
The utility model content:
At the existing problem of background technology, the purpose of this utility model is to provide the LED grid that a kind of illumination is even, utilization rate is high back light, is intended to solve the problem that LED-backlit light source production cost is high in the prior art, the illumination utilization rate is low.
In order to realize above-mentioned technical problem, the utility model provides a kind of LED grid backlight, and its structure comprises circuit board, and the two doublings of LED and electronics are installed on the circuit board, and the circuit board stably fastening is in the plastic cement lid.
Described plastic cement lid is made up of the loam cake of being located at circuit board surface and the lower cover of being located at circuit board bottom surface.The lid of employing plastic cement material can reach easily to be installed, dismantles, and omits screw, more firm purpose and effect after circuit board is fastened.
Further step is that when described circuit board was the constant voltage circuit plate, the LED quantity on its circuit board was at least three.
When described circuit board was the constant-current circuit plate, the LED quantity on its circuit board was at least one.
Be connected conducting by the two doublings of the electronics on it between circuit board and the circuit board.
The utility model passes through such scheme, make the structural design of a whole set of LED grid backlight very scientific and reasonable, it is low that a whole set of products has power consumption, and heat is little, splices convenient, flexible, luminous even, flicker free, the characteristics of safe and reliable and energy-saving and emission-reduction are to produce bigger economic results in society, filled up the deficiency of market, present LED-backlit source application product, fabulous market prospects have been arranged.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Among the figure, 1, circuit board, 2, LED, 3, the two doublings of electronics, 4, loam cake, 5, lower cover.
The specific embodiment:
As shown in Figure 1, evenly be placed with LED2 on the circuit board 1 of the present utility model, the two doublings 3 of electronics are welded on the surface of circuit board 1, for reaching purpose easy for installation, described lid adopts plastic cement material, after circuit board 1 is fixed in lower cover 5, loam cake 4 is got final product with lower cover 5 corresponding fastenings.Reach the omission screw, can conveniently install again, dismantle, with circuit board 1 fasten more firm purpose.
Shown in the figure is that two circuit boards are arranged in parallel, and is connected conducting by the two doublings 3 of the electronics on it between circuit board and the circuit board, during energising work luminous evenly, flicker free, the structure of a whole set of LED grid backlight is very scientific and reasonable.
Certainly, be a specific embodiment of the present utility model shown in the figure, be not technical scope of the present utility model is imposed any restrictions.The technical staff of the industry, under the inspiration of the technical program, can make some distortion and revise, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any modification, equivalent variations and modification that above embodiment does.
