Description

It is a kind of to have two kinds of LED lamps for going out optical mode

Technical field

The utility model relates to lighting area more particularly to LED light.

Background technique

Existing lamp on the market only has simple function, only realization oriented lamp or non-directional simple function.But user Usage scenario be often change, the same position needs directional lighting sometimes, needs strary lighting sometimes, User will be very difficult when selecting lamps and lanterns in this way, and it is increasingly increased that the lamps and lanterns of simple function can not meet well user Demand.

Utility model content

The utility model provides technical problem underlying to be solved and is to provide a kind of LED lamp, be provided simultaneously with orientation and Non-directional modulation characteristic.

In order to solve the above technical problems, the utility model provide it is a kind of have two kinds go out optical mode LED light Tool, comprising: light source board, concentrating component and astigmatism component；

It is divided to two region setting LED chips, wherein LED chip sending in first area on the same face of the light source board Light is emitted formation fixed point illumination after concentrating component, i.e., is fixed when the LED chip in only first area is lighted To lamp；The light that LED chip in second area issues is emitted after astigmatism component forms strary lighting, i.e., when only second It is non-directional lamp when LED chip in region is lighted；When the LED chip in first area and second area is lighted simultaneously For non-directional lamp.

In a preferred embodiment: the first area and second area are distributed in concentric circles.

In a preferred embodiment: the concentrating component includes lens, and the lens have an opening face；The lens are opened The periphery in mouth face is connect with the white space, so that the light that the LED chip in the first area issues all passes through institute Lens are stated to be emitted outward.

In a preferred embodiment: the concentrating component further includes reflector, the both ends of the reflector axially point It Wei not the first open end and the second open end；Reflector is located at outside lens by the first open end, so that being emitted by lens Light in a part projected outward after reflector is reflective.

In a preferred embodiment: the knot that the reflector to the second opening there is diameter to gradually increase by the first opening Structure.

In a preferred embodiment: the astigmatism component is light-guiding shade, the light warp that the LED chip in second area issues It is projected after crossing light-guiding shade leaded light from two sides.

In a preferred embodiment: further including driving circuit, the driver circuit controls LED chip list in two regions Solely lights or light or extinguish simultaneously simultaneously.

Compared to the prior art, the technical solution of the utility model have it is following the utility model has the advantages that

The utility model provide it is a kind of have two kinds go out optical mode LED lamps, oriented lamp, non-directional lamp are fused to One can effectively reduce the selection of client lamp kind, and a kind of lamp can match different usage scenarios, avoid client for lamp The puzzlement of kind type selecting.

Specific embodiment

The utility model patent is described further in the following with reference to the drawings and specific embodiments.

It is a kind of to have two kinds of LED lamps for going out optical mode, comprising: light source board 1, concentrating component 2 and astigmatism with reference to Fig. 1-3 Component 3；

It is divided to two region setting LED chips on the same face of the light source board 1, wherein LED chip is sent out in first area 11 Light out is emitted formation fixed point illumination after concentrating component 2, i.e., lights when the LED chip in only first area 11 When be oriented lamp；The light that LED chip in second area 12 issues is emitted after astigmatism component 3 forms strary lighting, It is non-directional lamp when the LED chip in only second area 12 is lighted；LED in first area 11 and second area 12 It is non-directional lamp when chip is lighted simultaneously.It thereby realizes two kinds and goes out optical mode non-interfering purpose independently of each other, The selection of client lamp kind can be effectively reduced so that oriented lamp, non-directional lamp permeate, a kind of lamp can match not Same usage scenario avoids puzzlement of the client for lamp kind type selecting.It is independent that LED chip in two regions is controlled by driving circuit It lights or lights or extinguish simultaneously simultaneously, so that it may allow user in directional lighting, stray illumination and orientation+stray illumination three It is freely switched among a mode.

In order to avoid the light that the LED chip in two regions issues interferes with each other, in the present embodiment, the first area 11 and second area 12 in concentric circles be distributed, and between first area 11 and second area 12 have a white space 13.

The concentrating component 2 includes lens 21, and the lens 21 have an opening face；The periphery in the opening of lens 21 face It is connect with the white space 13, so that the light that the LED chip in the first area 11 issues is all by the lens 21 outgoing outward.

In order to further decrease the shooting angle of light in concentrating component, increase spotlight effect, the concentrating component 2 also wraps Reflector 22 is included, the both ends of the reflector 22 axially are respectively the first open end and the second open end；Reflector 22 is logical It crosses the first open end to be located at outside lens 21, so that a part is reflective backward by reflector in the light being emitted by lens 21 Outer injection.Emergent ray after the reflection of reflector 22, the angle of emergence further decrease, and spotlight effect becomes apparent from.

In the present embodiment, the reflector 22 has the structure that gradually increases of diameter by the first opening to the second opening.

The astigmatism component 3 is light-guiding shade, and the light that the LED chip in second area 12 issues is after light-guiding shade is guide-lighting It is projected from two sides.The structure of light-guiding shade and the light guide plate of panel light are similar, LED chip issue light from the side of light-guiding shade into Enter in light-guiding shade, and propagated along the direction that light-guiding shade extends, ultimately forms the scattering light of wide-angle.

The preferable specific embodiment of the above, only the utility model, but the design concept of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, utilizes this design The change that unsubstantiality is carried out to the utility model belongs to the behavior for invading scope of protection of the utility model.
