Abstract

The utility model discloses a LED unit and a LED lampwick made of LED units. The LED unit is composed of a support board which consists of support boards of erected multi-edge platforms and of headstand multi-edge platforms; the LEDs which are electrically connected are installed on each edge plane of the support board of the headstand multi-edge platforms; devices which can be fixedly connected with each other are respectively installed on the upper end face and the lower end face of the support board. The LED lampwick consists of one or more LED units which are fixedly connected with each other and the main anode and the main cathode of the LED units are separately connected electrically, or a plurality of the LED units are electrically connected with each other and other units are separately and electrically connected, or all the LED units are electrically connected with each other. The LED of the LED units of the utility model slants naturally downwards, thereby the LED lampwick in a lantern shape can be freely assembled with beautiful appearance. The utility model has convenient use and energy conservation; the LED light source with different colors can be realized by fixedly installing LED according to different color requirements on a printed circuit board. Only by fabricating dies of the LED units, the LED lampwick with different shapes can be produced.

Description

The LED light fixture wick of a kind of LED unit and composition thereof

One, technical field:

The LED light fixture wick that the utility model belongs to a kind of LED unit and is made up of this unit.

Two, background technology:

Existing LED light fixture is mainly used in outdoor lightings such as Lawn lamp, garden lamp and street lamp, and people respectively have hobby to the requirement of light fitting shape, and the shape of LED light fixture is single at present, can not satisfy people's needs.Especially adopt printed substrate to make the LED light fixture of gripper shoe, printed substrate has all been made one flat plate, it is vertically mounted on a plurality of LED on the printed substrate according to a definite sequence, the pin of LED then is welded on the side of printed substrate, its shape is more single, underground for the light directive, its illuminated area can only downward-slopingly be installed, and installing engineering is bigger; And the LED on the whole plate face all is electrically connected, and can't realize making a part of LED bright according to the lamp lighting needs, and a part of LED goes out, and wastes energy.Adopting the LED light fixture of integral insulation gripper shoe also is that LED is arranged on the integral insulation gripper shoe according to certain mode, connect according to the electric connection mode of LED is whole, not only shape is single, can not realize making a part of LED bright according to the lamp lighting needs, and a part of LED goes out; And insulation support plate is a global shape, and a shape is opened a mould, waste fund.

Three, summary of the invention:

The purpose of this utility model is exactly to solve now with the problems referred to above that exist in the technology, the LED light fixture wick of a kind of LED unit and composition thereof is provided, adopt this LED unit can form the LED wick that the cross section is various polygonal folding lamp cage type shapes, its needs are opened the mould of LED unit, just can produce the LED light fixture wick of multiple shape.

For finishing the purpose of this utility model, its technical solution is: a kind of LED unit, and it is made up of a positive multi-pyramid gripper shoe and the terrace with edge gripper shoe is formed more than one gripper shoe and a plurality of LED; LED is installed on each faceted pebble of many terrace with edges gripper shoe, and the electric connection mode according to LED between each LED connects, and total positive pole and total negative pole are drawn by lead; Gripper shoe upper surface and lower surface are fixed with the device that can install and fix together respectively.

Above-mentioned described LED is installed on each faceted pebble of many terrace with edges gripper shoe by little printed substrate, have the installing hole of a little printed substrate on each faceted pebble of many terrace with edges gripper shoe, described LED is fixed on each little printed substrate, little printed substrate is installed in the installing hole, little printed substrate is printed according to the electric connection mode of LED, be electrically connected between the LED on each little printed substrate, total positive pole and total negative pole are drawn by lead.Like this, reduced the electrical connecting wire between the LED, wiring is simple, reliable, saves artificial.

Above-mentioned described little printed substrate is removably mounted in the installing hole on many terrace with edges gripper shoe.Like this, the partial LED when the LED unit breaks down, and can change separately, to increase its service life.

LED fixing on the above-mentioned described little printed substrate is four pin LED, and four pin LED are vertically fixed on the little printed substrate.

LED fixing on the above-mentioned described little printed substrate is bipod LED, and bipod LED is vertically fixed on the little printed substrate.

Many terrace with edges of above-mentioned described positive multi-pyramid gripper shoe and many terrace with edges gripper shoe are three terrace with edges, truncated rectangular pyramids, five terrace with edges, six terrace with edges, seven terrace with edges, eight terrace with edges or other any many terrace with edges.

Above-mentioned described positive multi-pyramid gripper shoe below, many terrace with edges printed substrate is in the above.

Above-mentioned described positive multi-pyramid gripper shoe in the above, many terrace with edges printed substrate is below.

A kind of LED light fixture wick of forming by above-mentioned LED unit, it is installed and fixed together by one or more LED unit and forms; Be electrically connected separately as required between total anodal and total negative pole of LED unit; Perhaps plurality of units is electrically connected mutually, and other unit is electrically connected separately; Perhaps all be electrically connected mutually, lead is drawn wick.

The LED of the LED unit that the utility model provides is tilted to down naturally, and it can be assembled into the LED wick that the cross section is various polygonal folding lamp cage type shapes arbitrarily, and it is beautiful attractive in appearance, can form the wick not of uniform size that different terrace with edge shapes are enumerated as required.Each LED unit can be electrically connected separately as required, and perhaps plurality of units is electrically connected mutually, so it can be the people for a long time, and how bright several LED unit, people late at night lacks bright several LED unit after a little while, and it is easy to use, the saving energy; And the LED that installs and fixes on the gripper shoe can be required to install according to different colours, can make versicolor led light source.And only need open the mould of LED unit, just can produce the LED light fixture wick of multiple shape, save cost of manufacture, the difform LED wick of being made up of the LED unit is easily formed large-scale production.Use the then wiring of little printed substrate simple, reliable, save artificial.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model is further described:
