As the circuit layer is directly fixed on the surface of the heat conductive layer, the heat generated by the LED bar can be directly conducted from the heat conductive layer to the radiator to radiate; the heat conductive property of the LED bar bracket is improved, and moreover, the service life of the LED bulb is improved.
Description
Technical field
The present invention relates to LED lamp field, particularly a kind of LED light strip 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 negative pole, and the other end connects the positive pole of power supply, makes whole 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 note, and the LED lamp bar in the LED lamp need to be installed on the LED light strip support and use.
Existing LED light strip support comprises: line layer and heat-conducting layer, line layer is used for being connected with the PCB substrate of LED lamp bar, 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 by insulating barrier again, 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 large, 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 only has LED striation front to send that can utilize causes the light extraction efficiency of LED lamp very low.
Also have, because the circuit on the line layer is connected, in the course of the work, if there is the circuit of certain to break down, then very likely cause whole LED lamp to work.
Summary of the invention
The technical problem that the present invention solves provides a kind of good heat conductivity, LED light strip support that light extraction efficiency is high.
For achieving the above object, the invention provides a kind of LED light strip support, comprising: heat-conducting layer and directly be fixed on the lip-deep line layer of described heat-conducting layer, and fix by cover plate, the up and down two ends of cover plate have the line layer mounting groove, and cover plate has the bonding wire groove corresponding with the 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 light strip support is provided with optical lens, and optical lens is fixing on the cover board by reference column.
Further, the circuit on the line layer is parallel connection or series circuit.
According to technical scheme of the present invention, because line layer directly is fixed on the heat-conducting layer surface, so that the heat that the LED striation produces directly conducts to radiator heat-dissipation by heat-conducting layer, improved the heat conductivility of LED light strip support, the useful life of further having improved led light source.

Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.
Referring to Fig. 1 a and Fig. 1 b, comprise according to first embodiment of the present invention LED light strip support: heat-conducting layer 1 and line layer 2, wherein, the material of heat-conducting layer 1 is metal or pottery, wherein, aluminium in the metal, copper is preferentially selected, pottery takes second place, 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, 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 by 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 the bonding wire groove 31 corresponding with the 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 by 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, the port of this draw-in groove 32 is horn-like, the cross section has up and down two reflective surfaces 321, the upper end crystal bonding area 323 of crystal heat-conducting plate 12 cooperates formation to hold the groove 322 of LED wafer with two reflective surfaces 321, the light that sends of LED striation side will by 321 reflections of two reflective surfaces, improve the light extraction efficiency of LED lamp like this.
LED striation lighting angle is larger, and it is better to play light-dispersing 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, such as Fig. 4 a, Fig. 4 b, Fig. 5 and shown in Figure 6, the LED light strip support is provided with the optical lens 4 for optically focused in the front according to a second embodiment of the present invention, optical lens 4 is fixed on the cover plate 3 by reference column, cover on the LED striation that is installed on the LED light strip support, optical lens 4 can be convex lens, is used for improving the luminous brightness of LED striation.
