Abstract

A kind of no light leakage LED light strip of the utility model, including flexible circuit board, multiple LED series units are welded on flexible circuit board, multiple series units are connected in parallel on the positive and negative power supply circuit of circuit board, circuit board is coated with core wire, and core wire two sides are embedded with positive and negative polarity wire respectively, and the positive and negative power supply circuit of circuit board passes through lead respectively and is connected in parallel to the positive and negative polarity wire, the core wire front is coated with translucent skin, and core wire side and the back side are coated with white or the opaque crust of yellow.Since the utility model core wire front is coated with translucent skin, core wire side and the back side are coated with white or the opaque crust of yellow, light is only issued from core wire front, core wire side and the back side do not have light leakage, decorative lighting effect is preferable, simultaneously because light bar light efficiency can be improved by side and back light line reflection to front in white or the opaque crust of yellow.

Description

A kind of no light leakage LED light strip

Technical field

The utility model relates to a kind of LED illumination lamps, more particularly to a kind of no light leakage LED light strip.

Background technique

Existing lower voltage LED lamp band welds LED02 on circuit boards, is arranged as shown in Figure 1, including flexible circuit board 01 Transparent silica gel casing 03 outside the circuit board.Due to be arranged outside light bar be all-transparent silica gel sleeve pipe 03, light can be from Light bar side and the back side leak out, and on the one hand will lead to the positive luminous intensity of light bar in this way and are weakened, and on the other hand also will affect lamp Light decorative effect.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of no light leakage LED light strip.

The utility model solves technological means used by its technical problem: a kind of no light leakage LED light strip, including flexibility Circuit board is welded with multiple LED series units on flexible circuit board, and multiple series units are connected in parallel to the positive and negative anodes of circuit board On power circuit, circuit board is coated with core wire, and core wire two sides are embedded with positive and negative polarity wire, the positive and negative power supply of circuit board respectively Circuit passes through lead respectively and is connected in parallel to the positive and negative polarity wire, and the core wire front is coated with translucent skin, core wire side White or the opaque crust of yellow are coated with the back side.

The beneficial effects of the utility model are: since the utility model core wire front is coated with translucent skin, core wire side It is coated with white or the opaque crust of yellow with the back side, light is only issued from core wire front, and core wire side and the back side do not have light leakage, Decorative lighting effect is preferable, simultaneously because white or the opaque crust of yellow can by side and back light line reflection to front, Light bar light efficiency can be improved.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of existing LED light strip；

Fig. 2 is the utility model structure diagram；

Fig. 3 is the structural schematic diagram of Fig. 2A-A section；

Fig. 4 is the electrical block diagram of one LED series unit of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

With reference to Fig. 2 and Fig. 4, a kind of no light leakage LED light strip, including flexible circuit board 1, be welded on flexible circuit board by The series unit 20 that LED2 and resistance 21 form.Multiple series units 20 are connected in parallel to the positive and negative power supply circuit of circuit board 1 Upper 11.Circuit board 1 is coated with core wire 3, and 3 two sides of core wire are embedded with positive and negative polarity wire 4, the positive and negative power supply of circuit board 1 respectively Circuit 11 is connected in parallel to the positive and negative polarity wire 4 by lead 5 respectively.With reference to Fig. 3, the cross section of the utility model core wire 3 Rectangular, wherein the light direction of LED is front F, opposite with positive F for back surface B, and positive F and back surface B two sides are side S.The 3 front F of core wire is coated with translucent skin 61, and core wire side S and back surface B are coated with white or the opaque crust of yellow 62.The translucent skin 61 and white or the opaque crust 62 of yellow are transparent gross rubber and white to be respectively adopted or yellow is opaque Sizing material inputs in same extrusion die extrusion molding simultaneously from different directions, to form translucent skin 61 and white or yellow is impermeable Bright 62 integral structure of crust.

As a further improvement of the utility model, the front of the core wire 3 using transparent material manufacture, core wire side and The back side is identical as crust using white or the manufacture of yellow opaque material, manufacture craft.

Since the utility model core wire front F is coated with translucent skin 61, core wire side S and back surface B be coated with white or The opaque crust 62 of yellow, light are only issued from the front of core wire 3, and 3 side of core wire and the back side do not have a light leakage, decorative lighting effect compared with It is good, simultaneously because light bar light can be improved by side and back light line reflection to front in white or the opaque crust of yellow Effect.
