Description

The wall lamp and street lamp of Optical devices and its composition

Technical field

The utility model relates to lighting areas.

Background technique

Lighting device in the prior art is direct-type, i.e. source light output illumination, when user sees light source Can be very dazzling, thus illuminating ray is not soft, illuminating effect is bad.In addition, existing lighting device is all mounted directly , monnolithic case is larger, and Integral decoration is ineffective, and for street lamp, existing street lamp is required to setting lamp stand, Along the vertical direction after frame up to predetermined altitude, there are also the upper pavement surface illuminations that cross bar extends to illumination, and structure is complicated.

Summary of the invention

To overcome the above disadvantages, the purpose of this utility model is to provide a kind of small volumes, the optics of maintaining uniform illumination Device.

In order to reach the goals above, the utility model provides a kind of Optical devices, including bottom surface, grand from the bottom surface Rise positive camber, from the bottom surface to the negative camber of the positive camber inner recess, the positive camber is by two or so Symmetrical semiellipsoid is spliced to form peanut shell-shaped, LED chip is equipped within the negative camber, from two semiellipsoids Combination center form a cutting plane to side cutting, at predetermined angular, described is interior for the cutting plane and the bottom surface The vertex of curved surface and the combination center of positive camber are located along the same line, wherein the cutting plane will be by negative camber incidence Light is all totally reflected towards the light-emitting surface of the other side, and the light-emitting surface will be all-trans by the light of negative camber incidence, cutting plane All deviation exports the light penetrated forward.

It is further improved as the utility model, setting reflection plated film on the cutting plane.

It is further improved as the utility model, optical microstructures is set on the cutting plane.

It is further improved as the utility model, including for adjusting LED chip central point and the negative camber top The regulating mechanism of distance between point.

It further improves as the utility model, is integrally prepared by glass or optical resin material.

Another aspect according to the present utility model provides a kind of wall lamp, from inner in the mounting hole including being located at facade It is disposed with cooling fin, aluminum substrate and Optical devices as described above outward, is put down where the Optical devices and facade The setting of face flush.

Another aspect according to the present utility model provides a kind of street lamp, including be located at facade mounting hole in from it is inner to It is disposed with cooling fin, aluminum substrate and Optical devices as described above, plane where the Optical devices and facade outside Flush setting.

It is exported as can be seen that the Optical devices of the utility model can only reflect light to side, in illumination region Uniform-illumination, human eye can not look at light source straight, and only for optical lens in the outside of mounting hole, decorative illumination effect is fine.In addition, due to It is light source and illumination region in subvertical distribution, is particularly suitable for the municipal works illumination of lane.

Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.

Referring to shown in each attached drawing 1 to attached drawing 3, attached drawing 1 be according to the stereoscopic schematic diagram of the Optical devices of the utility model, it is attached Fig. 2 is according to the main view of the Optical devices of the utility model, and attached drawing 3 is looking up according to the Optical devices of the utility model Figure.Present embodiment discloses a kind of Optical devices, the positive camber 2 that is swelled including bottom surface 1, from bottom surface 1, from the outside curved surface 2 in bottom surface 1 The negative camber 3 of inner recess, optical lens are integrally prepared by glass or optical resin material.Positive camber 2 is by two or so Symmetrical semiellipsoid is spliced to form peanut shell-shaped, LED chip 4 is equipped within negative camber 3, the effect of negative camber 3 is light The line plane of incidence, the vertex of negative camber 3 and the combination center 5 of positive camber are located along the same line.

A cutting plane 6, cutting plane 6 and bottom surface 1 are formed from the combination center 5 of two semiellipsoids to side cutting at predetermined Angle, to form the angle being totally reflected, setting reflection plated film or optical microstructures on cutting plane 6, to enhance the complete of cutting plane 6 Reflecting effect.

In another embodiment of the utility model, a regulating mechanism can also be set, for adjusting in LED chip The regulating mechanism of distance between heart point and the introversion vertex of surface, can light modulation effect during the installation process, such as light quantity or The fine tuning of person's hot spot.

Referring to shown in attached drawing 4, present embodiments providing a kind of wall fitting lamp, in the mounting hole 8 including being located at facade 7 from In be disposed with cooling fin 9, aluminum substrate 10, LED chip 12 and Optical devices 11 outward, Optical devices 11 and 7 institute of facade It is arranged in plane flush.

Referring to shown in attached drawing 5, a kind of street lamp is present embodiments provided, it is similar to attached drawing 4 including vertical positioned at both sides of the road Cooling fin 9, aluminum substrate 10, LED chip 12 and Optical devices 11, light are disposed in the mounting hole 8 in face 7 inside-out It learns device 11 and 7 place plane flush of facade is arranged.

Referring to shown in each attached drawing 6 and attached drawing 7, attached drawing 6 is the optical schematic diagram of attached drawing 4 and attached drawing 5, and attached drawing 7 is 4 He of attached drawing The optical effect figure of attached drawing 5.Since cutting plane 6 is complete by the light-emitting surface 2 by the incident light of negative camber 3 all towards the other side Reflection, by the light being totally reflected by the incident light of negative camber 3, cutting plane 6, all deviation exports light-emitting surface 2 forward.It can see Out, light is only emitted by the utility model from below, the uniform-illumination in illumination region, is in connect due to being light source with illumination region Nearly vertical distribution is particularly suitable for the municipal works illumination of lane.It is to be located at that entire lamps and lanterns, which only have small lens component, The outside of wall, other parts are hidden among the mounting hole of wall, and decorative effect is fine.Under illumination condition, human eye Can not look at light source straight, user will not direct view led chip, dazzling effect will not be generated.Light can rationally be utilized, realize that unilateral side goes out The purpose of light, and can be big to reach the length and width on lens light direction by changing the hot spot design value of lens It is small, it is also applied for being mounted on the application of the wall lamp, emergency light on wall.

Embodiment of above is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill The people of art understands the content of the utility model and is implemented, and does not limit the protection scope of the present invention, and all According to the equivalent change or modification that the spirit of the present invention is substantially done, should all cover within the protection scope of the present utility model.
