Abstract

The utility model discloses a trapezoidal LED unit and the formed LED lamp core. The trapezoidal LED unit is composed of a reversed trapezoidal printing circuit board and a plurality of LEDs mounted on the printing circuit board and the upper and lower end surfaces of the printing circuit board have the structures capable of installing and connecting into a whole. The LED lamp core is formed by installing and fixing more than three LED units and the three LED units are connected with each other in electricity; leads educe the lamp core. The utility model is able to be assembled into the LED lamp cores of different prismoid shapes and the LED of the LED lamp core incline downward naturally, which is simple and reliable in connection and saves the labor. Besides, the utility model, only needs to open the module of the LED unit, is able to produce with LED lamp cores of a plurality of shapes, which saves the producing cost and is easy for forming the scaled production.

Description

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

One, affiliated technical field:

The utility model belongs to the LED light fixture wick of a kind of LED unit and composition thereof.

Two, background technology:

People respectively have hobby to the requirement of light fitting shape, so the light fixture of different shape arises at the historic moment.Existing LED light fixture is mainly used in outdoor lightings such as Lawn lamp, garden lamp and street lamp, and its modeling requirement to light fixture is higher.The substrate of the wick of existing LED light fixture adopts a kind of insulation support plate, has aperture on insulation support plate, in the pin insertion aperture with LED, another side at insulation support plate connects electric wire, and there are a lot of shortcomings in this light fixture: because it is little to form the LED of LED light fixture, number is many, the wiring complexity, easily snap, easily virtual connection, connection reliability is poor, the lost labor, and insulation support plate is a global shape, and a shape is opened a mould, waste fund.And use printed substrate to do the LED light fixture wiring reliability height of gripper shoe, save artificial, so, most LED light fixtures such as street lamp adopt printed substrate to do to support and pull, and printed substrate has all been made flat pulling, 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 single, can not satisfy the requirement of people to LED light fixture shape, underground for the light directive, its illuminated area can only downward-slopingly be installed, and installing engineering is loaded down with trivial details.

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 trapezoidal LED unit and composition thereof is provided, adopt trapezoidal LED unit can form the LED light fixture wick of various terrace with edge shapes, its needs are opened the mould of LED unit, just can produce the LED light fixture wick of multiple shape, and wiring is simple, reliable.

For finishing the purpose of this utility model, its technical solution is: a kind of trapezoidal LED unit, it falls trapezoidal printed substrate and be installed in that a plurality of LED on the printed substrate form by one, printed substrate is printed according to the electric connection mode of LED, the pin of LED is welded on the printed substrate, in printed substrate upper surface and lower surface the structure that can install and fix is together arranged respectively.

Described LED tilts to be installed in down on the trapezoidal printed substrate.

Described LED is vertically mounted on down on the trapezoidal printed substrate.

Above-mentioned described LED is bipod LED.

Above-mentioned described LED is four pin LED, the described trapezoidal printed substrate upper end on the position of each four pin LED of falling has the aperture that is complementary with the LED pin, the lower end has a slotted hole, pin above the four pin LED inserts in the aperture, crouch in slotted hole in the lower end of LED, to reach the purpose that four pin LED tilt to install.

The number of above-mentioned described LED is four multiple.

A kind of LED light fixture wick of forming by above-mentioned described LED unit, it is installed and fixed together by three above LED unit and forms; Be electrically connected mutually between the LED unit, lead is drawn wick.

Be fixed together by the polygon clip between the LED unit of above-mentioned described LED light fixture wick, the limit of its polygon clip is identical with the LED unit number of forming wick.Have on the polygon clip and can install and fix the structure that structure together is complementary and is fixed together on the printed substrate with the LED unit.

Vertical or downward-sloping being fixed on down on the trapezoidal printed substrate of the LED of the LED unit that the utility model provides, it can be assembled into the LED wick of different terrace with edge shapes arbitrarily, and LED is downward-sloping naturally, and its wiring is simple, reliable, saves artificial.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.

Four, description of drawings

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

Fig. 1 is the front view of a kind of embodiment of four pin LED unit of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the upward view of a kind of embodiment of the utility model LED light fixture wick;

Fig. 4 is the front view of Fig. 3.

Five, the specific embodiment:

As shown in Figure 1 and Figure 2, present embodiment falls trapezoidal printed substrate 1 and be installed in that a plurality of four pin LED 2 on the printed substrate 1 form by one.Printed substrate 1 upper end on the position of each four pin LED 2 has two apertures 4 that are complementary with four pin LED, 2 pins, and the lower end has a slotted hole 3, and each two pin above the four pin LED 2 inserts in two apertures 4, crouches in the slotted hole 3 in the lower end.The number of LED is 40, and it is staggered on printed substrate 1.Printed substrate 1 is printed according to the electric connection mode of four pin LED 2, and four pin of LED 2 are welded on the printed substrate 1, have the fixing hole that can install and fix together in the top and bottom of printed substrate 1.

As shown in Figure 3, Figure 4, present embodiment LED light fixture wick is to be installed together by 6 LED unit as depicted in figs. 1 and 2 to form.6 LED unit are fixed into one six terrace with edge light fixture wick by the top hexagonal clip that has fixing hole; Fixing hole on fixing hole on the clip and the four pin LED unit is fixed together by screw.Be electrically connected mutually between the LED unit, lead is drawn wick.
