Description

A kind of side-emitting LED light bar

Technical field

The utility model relates to a kind of side-emitting LED light bar.

Background technique

Currently, LED light in the market has positive luminescence LED light bar and side-emitting LED light bar, positive luminescence LED light bar is emphasized Be illuminating effect — that is, have adequate brightness light；Side-emitting LED light bar intensity is dicoration, generates soft light, is compareed Brightness requires low.Positive luminescence LED light bar refers to that the front for being equipped with the wiring board of LED lamp bead as light-emitting surface, reaches more preferable Brightness of illumination；

The luminous LED light strip in side first shelters from the positive light for the wiring board for being equipped with LED lamp bead, and assist side Side goes out light.

Side-emitting LED light bar specific structure is as shown in Figure 1, including the LED on wiring board 1E, the layout front assist side 1E Light transmission plastic jacket 3E outside lamp bead 2E, package assist side 1E, wherein fluted 6E, route is arranged in light transmission plastic jacket 3E Plate 1E is embedded into inside groove 6E, and the surface of light transmission plastic jacket 3E is also equipped with front barn door 4E and back side barn door 5E, And there are light out part 8E, front barn door 4E blocks the light of the sending of the positive direction of LED lamp bead 2E, in the side of groove 6E It is provided with and receives unthreaded hole 7E, receive unthreaded hole 7E and be located at the side wiring board 1E, light out part 8E is located at the outside for receiving unthreaded hole 7E.

This side-emitting LED light bar has the following disadvantages: 1) groove 6E and receipts unthreaded hole 7E at a distance, positive shading The front that plate 4E only shelters from groove 6E, which does not extend to, receives the side unthreaded hole 7E, some light (1/3 that LED lamp bead 2E is issued Light) process receipts unthreaded hole 7E just directly goes out for some, influence light efficiency and decorative effect, and not energy-efficient and environmental protection；2) due to Only the laying LED lamp bead 2E on front, only front shine wiring board 1E, and the back side wiring board 1E does not shine, and natively exists Light out part 8E has that two sides light and shade is uneven, if there is 1/3 light is not by receiving unthreaded hole 7E, will be further exacerbated by light and shade Uneven situation.

Summary of the invention

One purpose of the utility model is to provide a kind of side-emitting LED light bar, to solve light out part in the prior art The dark technical problem in one marginal ray, one side.
