Abstract
The utility model relates to an indoor LED lamp. Two structures are generally adopted for light distribution of existing LED indoor lamps. According to one of the structures, the combination of a light-emitting angle of an LED and a transparent cover is adopted, therefore, strong glare can be generated through the light distribution structure, and people can feel uncomfortable. According to the other structure, light evening can be conducted on an LED light source through a diffuse reflection frosted surface, the luminous efficiency of the LED can be greatly reduced due to the light distribution, and the energy conservation property of the LED light source can not be well embodied. The indoor LED lamp comprises LED light sources (1) and is characterized in that the LED light sources (1) are arranged on a circuit board (2), a condensation element (3) is arranged in front of the LED light sources (1), and a light distribution element (4) is arranged in front of the condensation element (3). The indoor LED lamp is used for light distribution.
Description
Technical field:
The utility model relates to a kind of indoor LED lamps.
Background technology:
The luminous intensity distribution of existing LED indoor lamp is generally taked two kinds of structures, and a kind of is to utilize the light emitting anger of LED own to add transparent face mask, and this light distribution structure can produce strong dazzle, and the people is not felt well.Another kind is to utilize the diffuse reflection frosting to carry out all light to LED light source, and this luminous intensity distribution can reduce the light efficiency of LED greatly, can not well embody the energy conservation characteristic of LED light source.
The utility model content:
It is a kind of for the LED light fixture provides a kind of mode simple that the purpose of this utility model is to provide, the light fixture that free from glare and light extraction efficiency are high.
The purpose of this utility model is achieved in that
A kind of indoor LED lamps, its composition comprises: LED lamp source, described LED lamp source is arranged on circuit board, and the place ahead, described LED lamp source is equipped with collective optics, and described collective optics the place ahead is equipped with light distribution element.
Described indoor LED lamps, described collective optics is made by optics PC or PMMA, and described light distribution element is that optics PC or PMMA make.
Described indoor LED lamps, described LED light source is positioned on the focus of described collective optics, the light sent by described LED light source first reaches described collective optics, optical transmittance is high, by the optical patterns on described collective optics, make irregular incident ray convert the class directional light to, the class directional light of outgoing arrives described light distribution element, by the optical patterns designed on described light distribution element, the class directional light is diffused to uniformly to the optical flat of appointment.
Described indoor LED lamps, described collective optics and described light distribution element one, be optically focused and luminous intensity distribution one body member.
Beneficial effect:
1. the utility model has solved to the conversion of distribution of light the glare problem that present stage LED light fixture causes by optical element.
2. the utility model, by utilizing spot light to convert luminous intensity distribution theory and the rational optical texture of area source to, has solved the huge light loss that present stage LED light fixture utilizes diffuse reflection frosting luminous intensity distribution to cause.
3. the utility model can make light reach the optical flat of appointment according to the illumination actual demand by the design of optical element, increases light utilization.
4. the utility model optical texture is simple, and manufacturing process is also very easy, and the development and production cost significantly reduces.The accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.In figure, 1 is LED light source, and 2 is circuit board, and 3 is collective optics, and 4 is light distribution element.
Accompanying drawing 2 is another kind of structural representations of the present utility model.In figure, 1 is LED light source, and 2 is circuit board, and 5 is optically focused and luminous intensity distribution one body member.
The specific embodiment:
Embodiment 1:
