Abstract

The utility model relates to a shadowless lamp which comprises a spherical surface plate-shaped lamp holder and a plurality of high-power super-brightness luminous diodes as condenser light source assemblies, wherein a plurality of condenser light source assemblies are respectively arranged on the inner spherical surface of the spherical surface plate-shaped lamp holder; the projection light of each condenser light source assembly is lapped at the focus point to form a lapped luminous spot with the weakened shade; and the radius of the inner spherical surface of the spherical surface plate-shaped lamp holder is equal to the light condensing distance. Because of the adoption of Fresnel lenses, the shadowless lamp can gather more light sent out by the high-power super-brightness luminous diodes, and the luminous intensity of the luminous spot is improved. Because of the arrangement of dismountable and replaceable light outlets, projection luminous spots with different shapes and sizes can be obtained through changing the shapes and the sizes of the light outlets according to the requirements. Because the Fresnel lenses are ultra-thin lenses, and occupy small space, so the structure of the shadowless lamp is compact. Because a spherical surface plate can simultaneously gather the light projected by a plurality of condensing light sources to a set irradiating surface, and the focus luminous spot without the luminous intensity can be formed.

Description

Shadowless lamp

Technical field

The utility model relates to a kind of light fixture, relates in particular to a kind of shadowless lamp.

Background technology

The light emitting diode of high-power super brightness has that long working life, energy consumption are low, the characteristics of device environmental protection.Along with development of semiconductor, the light emitting diode of high-power super brightness enters to be commercially produced in recent years.As novel light-emitting component, high-power superhigh brightness LED is widely used, and will substitute traditional light source gradually in the near future.

Traditional light source shadowless lamp generally is made up of conventional bulb and concentrator.Conventional bulb places the focus of concentrator, and the light that conventional bulb is sent is converged by concentrator, projects illumination place and forms the no shadow hot spot that focuses on.

Conventional bulb certainly leads to heat when luminous, and contains infrared ray and ultraviolet ray at the light that sends.Can produce harmful effect to personnel.

The utility model content

The purpose of this utility model exactly in order to address the above problem, provides a kind of shadowless lamp that weakens hatching effect and can not produce harmful light radiation that has.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of shadowless lamp, the condensation light source module that comprises a spherical plate shape lamp socket and a plurality of high-power superhigh brightness LEDs, a plurality of condensation light source modules are installed in respectively on the Internal Spherical Surface of spherical plate shape lamp socket, the throw light of each condensation light source module is overlapping at focus point, formation has the overlapping hot spot that weakens shade, and the radius of the Internal Spherical Surface of spherical plate shape lamp socket equals the optically focused distance.

The condensation light source module of described high-power superhigh brightness LED comprises base, high-power superhigh brightness LED, lens mount, Fresnel Lenses and light-emitting window, high-power superhigh brightness LED is installed in the base center, in lens mount is installed on the base and light emitting diode is enclosed in, Fresnel Lenses is inlaid in the front portion of lens mount, the central shaft of Fresnel Lenses overlaps with the central shaft of light emitting diode, and light-emitting window is removably mounted on the front end of lens mount.

Described light-emitting window comprises the shape of a plurality of light holes and the light-emitting window that varies in size.

The lateral surface of described base is the adaptive spherical cambered surface of Internal Spherical Surface with spherical plate shape lamp socket.

The fin that runs through inside and outside a plurality of is installed on the described spherical plate shape lamp socket, and medial surface is provided with a plurality of grooves that are used to install condensation light source module, and the lateral surface of described condensation light source module base is provided with the boss adaptive with above-mentioned groove.

The utility model shadowless lamp makes it compared with prior art owing to adopted above technical scheme, have following advantage and and characteristics:

1, owing to adopted Fresnel Lenses, can converge the light that more sends, improve the illumination of hot spot by high-power superhigh brightness LED;

2, owing to be provided with the light-emitting window of detachable replacement, can change the shape and the size of its light hole on demand, to obtain the projected spot of difformity and size;

3, because Fresnel Lenses is a kind of ultra-thin lens, institute takes up space little, makes the shadowless lighting modulated structure more compact.

4, because spherical plate can converge to the light of a plurality of condensation light source projections the shadow surface of setting jointly, can form focal beam spot with no shadow degree.
