Deng or the structure of similar articles.

Background technology

The light that light-emitting diode sent of general traditional usefulness is forward light, it is with after circuit board combines, make light-emitting diode send the light of which kind of direction, the simplest mode, promptly be to change the position that circuit board installs, in the time of for example will making light-emitting diode send lateral light, circuit board be vertically installed in the board, bowing to the light time and light-emitting diode is sent, is the top of circuit board being located at board.

Another kind of improved procedure, please join shown in Figure 1ly, announce No. 433522 in " lateral light-emitting diode device ", it comprises: one first pin A, this first pin A upper end is provided with an optically focused ring cover A1 in order to this light-emitting diode of bearing C, and the light-emitting window of this optically focused ring cover A1 up; One second pin B; This second pin B upper end is suitable spacing setting with this first pin A upper end; One light-emitting diode C, this light-emitting diode C are installed in this optically focused ring cover A1; One printing opacity sizing material D, this optically focused ring cover of its capping A1, light-emitting diode C and the first pin A and the second pin B first half, and this first pin A and the second pin B Lower Half are exposed; By this, but the Lower Half of this first pin A of lateral bending and the second pin B and form an E of lateral bending portion respectively, the light that can make this wafer launch penetrates via this light-emitting window and printing opacity sizing material side direction, and form a better lateral light-emitting diode device, the cost of pressing mold processing procedure is greatly reduced.

In brief, above-mentioned patent is the light-emitting diode that will make, is provided with a bending angle in pin portion, makes the forward light that upwards penetrates originally form the lateral light that the side is penetrated.Right above-mentioned mode only is to change position or the angle that light-emitting diode installs, the emitted light of light-emitting diode can be reached use required direction, but it can't make the light of those ejaculations have more special variation, so still do not meet the required of use on reality is used.

Summary of the invention

Main purpose of the present utility model is in the improvement structure that a kind of side direction type solid-state semiconductor light-emitting component is provided, combination design by light-emitting diode and lens, make light-emitting diode need not bend the position of pin or the setting of change circuit board, the light that order is sent is via the guiding again of lens, to reach excellent side direction light source effect, pass through the variation of lens circumferential surface again, the side direction light source is changed thereupon, to increase its practicality.

In order to achieve the above object, the utility model mainly is provided with a LED package and lens, wherein these lens are located at this LED package front end surface, the light that comes from this light-emitting diode with reception, and, make the light that comes from these lens can fall within the side direction periphery of this LED package, again with the guiding again of received light mat refraction part, the periphery mask of these lens is provided with as protruding or recessed variation, makes this side direction light change with the variation of circumferential surface.

Other characteristics of the present utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..

Embodiment

Please be with ginseng Fig. 2, Fig. 3, the utility model side direction type solid-state semiconductor light-emitting component comprises: a LED package 10 and lens 20, these lens 20 from top to bottom envelope the chip 11 of LED package 10 to finish assembling; These lens 20 roughly are made as a cylinder, the bottom of these lens 20 is concaved with an accommodation space 22, so that the chip 11 of this LED package 10 is placed in wherein, and the top of these lens 20 is gradually recessed to the center of circle by periphery, this recessed face is made as refraction part 21, and the outboard peripheries at these lens 20 tops (being recessed face) then forms projection unit 23, this projection unit 23 is a burnishing surface that light is evenly penetrated, the light that chip 11 is upwards penetrated, refraction through lens 20 refraction part 21, this light that is refracted is on average penetrated by the projection unit 23 of side direction periphery, make forward light be led again and form lateral light.

Please join Fig. 4, be the first preferable application examples of the utility model embodiment, these lens 20 are made as cylinder equally, the bottom is provided with for the accommodation space 22 that coats these LED package 10 chips 11, the top also is provided with to the gradually recessed refraction part 21 in the center of circle, and this projection unit 23 is made as concave surface by burnishing surface, make the refraction of light that chip 11 upwards penetrates, penetrate by the projection unit 23 of side direction periphery through refraction part 21, yet, this projection unit 23 is set as concave surface, this concave surface then forms the concavees lens that make light scatter, as shown in Figure 5, and by this, make the side direction light source that is provided have more variability, to increase its practicality.

Please join Fig. 6～Fig. 7 again, lens 20 of the present utility model, this projection unit 23 also can be changed by burnishing surface and is made as convex surface, when using, forward light with chip 11 sends forms lateral light after the refraction of refraction part 21,23 projections of the projection unit through being made as convex surface again of this lateral light, make light as focusing on as the convex lens that can focus on, the light that order is penetrated has focus.

As from the foregoing, device of the present utility model has following practical advantage:

1, will penetrate the light-emitting diode of forward light, under the situation of angle that does not change pin and installation position, forward light will be directed to excellent side direction light source again.
