Abstract

The present utility model discloses an LED light strip support. The LED light strip support comprises a heat conducting layer and line layers directly fixed on the surface of the heat conducting layer, the layers are fixed through a cover plate, the upper and lower ends of the cover plate are provided with line layer installing grooves, and the cover plate is provided with welding wire grooves corresponding to the line layer installing grooves. As the line layers are directly fixed on the surface of the heat conducting layer, heat generated by an LED light strip is directly conducted from the heat conducting layer to the radiator to be radiated, thus heat conducting performance of the LED light strip support is increased, and service life of an LED light is further increased.

Description

LED striation support

Technical field

The utility model relates to LED lamp field, particularly a kind of LED striation support.

Background technology

LED (Light Emitting Diode), light-emitting diode is a kind of solid-state semiconductor device, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.LED lamp bar has another name called LED lamp band, and English name is LEDStrip, and shape resembles a belt, is that the LED with high brightness installs on the PCB substrate as the luminous element card, and the LED lamp bar in the LED lamp need be installed on the LED striation support and use.

Existing LED striation support comprises: line layer and heat-conducting layer, line layer are used for being connected with the PCB substrate of LED lamp bar, and two-layer centre is separated by insulating barrier; Be used for guaranteeing the insulation of line layer and heat-conducting layer, but just cause like this caloric requirement when luminous to conduct to the heat-conducting layer heat radiation again through insulating barrier, heat conductivility is poor; Thermal conductivity generally only has 0.8-2.8W/M.K; Because heat conductivility is poor, the light source light decay after causing encapsulating is very big, has a strong impact on the useful life of LED lamp.

In addition, the LED striation is inlaid in the mounting groove of insulating barrier, and the sidewall of this mounting groove is vertical with the bottom surface, and therefore, the complete crested of light that LED striation side emits is fallen, and the light that has only LED striation front to send that can utilize causes the light extraction efficiency of LED lamp very low.

Also have,, in the course of the work,, then very likely cause the whole LED lamp can't operate as normal as if there being the circuit of certain to break down because the circuit on the line layer connect.

The utility model content

The technical problem that the utility model solves provides a kind of good heat conductivity, LED striation support that light extraction efficiency is high.

For achieving the above object; The utility model provides a kind of LED striation support; Comprise: heat-conducting layer and directly be fixed on the lip-deep line layer of said heat-conducting layer; And fix through cover plate, the two ends up and down of cover plate have the line layer mounting groove, and cover plate has and the corresponding bonding wire groove of line layer mounting groove.

Further, heat-conducting layer comprises: base plate be positioned at the vertical outward extending crystal heat-conducting plate in base plate middle part, line layer is separately fixed at the both sides of crystal heat-conducting plate.

Further, the port of LED striation draw-in groove is horn-like, and the cross section has two reflective surfaces, and the upper end crystal bonding area of crystal heat-conducting plate cooperates formation wafer groove with two reflective surfaces.

Further, the front of LED striation support is provided with optical lens, and optical lens is fixing on the cover board through reference column.

Further, the circuit on the line layer is parallel connection or series circuit.

Technical scheme according to the utility model; Because line layer directly is fixed on the heat-conducting layer surface; The heat that makes the LED striation produce directly conducts to radiator heat-dissipation by heat-conducting layer, has improved the heat conductivility of LED striation support, the useful life of further having improved led light source.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection range that is to be understood that the utility model does not receive the restriction of embodiment.

Referring to Fig. 1 a and Fig. 1 b, comprise according to the first embodiment LED striation support of the utility model: heat-conducting layer 1 and line layer 2, wherein; The material of heat-conducting layer 1 is metal or pottery, and wherein, aluminium, copper are preferentially selected for use in the metal; Pottery takes second place, and as shown in Figures 2 and 3, structure comprises: base plate 11 and the crystal heat-conducting plate 12 that is arranged in these base plate 11 middle parts vertical outwards (the figure left side) extension; Line layer 2 directly is fixed on respectively on heat-conducting layer 1 upper surface, and the upper surface of bottom surface and heat-conducting layer 1 is fitted, and about in the of 12 both sides to be positioned at the crystal heat-conducting plate; And fixing through cover plate 3, cover plate 3 is plastic body or pottery, two ends have line layer mounting groove (not marking among the figure) up and down; The left end of this cover plate 3 has and the corresponding bonding wire groove 31 of line layer mounting groove; Two pins of the both positive and negative polarity of LED striation are connected with following corresponding line layer 2 respectively through this bonding wire groove 31, form the draw-in groove 32 of clamping crystal heat-conducting plate 12 in the middle of the sidewall of two bonding wire grooves 31, and the port of this draw-in groove 32 is horn-like; The cross section has two reflective surfaces 321 up and down; The upper end crystal bonding area 323 of crystal heat-conducting plate 12 cooperates with two reflective surfaces 321 and forms the groove 322 hold the LED wafer, and the light that sends of LED striation side will be by 321 reflections of two reflective surfaces like this, the light extraction efficiency of raising LED lamp.

LED striation lighting angle is big more, and it is good more to play astigmatic effect, but relative, its luminous brightness has also reduced with regard to corresponding; Lighting angle is little, and light intensity has been up, but the scope of irradiation can be dwindled again.Therefore; Like Fig. 4 a, Fig. 4 b, Fig. 5 and shown in Figure 6; The second embodiment LED striation support according to the utility model is provided with the optical lens 4 that is used for optically focused in the front, optical lens 4 is fixed on the cover plate 3 through reference column, covers on the LED striation that is installed on the LED striation support; Optical lens 4 can be convex lens, is used to improve the luminous brightness of LED striation.

In addition, the circuit on the line layer 2 of this LED striation support is a parallel circuits, in the course of the work, if there is the circuit of certain to break down, then can not cause the whole LED lamp can't operate as normal.Circuit on the line layer 2 of this LED striation support also can be series circuit.Common four of this LED striation support connects use (like Fig. 7 and shown in Figure 8) side by side.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection range of the utility model.
