Abstract

The utility model provides an LED light fixture with an increased light-emitting angle and an expanded illumination range. The LED light fixture comprises a substrate used for fixing LED lighting chips and the LED lighting chips; the substrate is shaped as a quadrangular frustum pyramid, with the upper surface being a square or rectangular flat surface and the four sides being inclined surfaces shaped as an isosceles trapezoid; and the LED lighting chips are distributed on the upper surface and the four sides of the substrate and are connected with a power source electrically. By employing a quadrangular frustum pyramid structure, instead of a conventional plane structure, as a structure of the substrate for fixing the LED lighting chips, the LED light fixture solves the problem of a small light-emitting angle of a conventional LED light fixture and realizes wide-angle light-emitting and large illumination range, thereby having more extensive applications.

Description

A kind of LED light fixture

Technical field

The utility model relates to the LED lighting technical field, more particularly, relates to a kind of LED light fixture that increases rising angle.

Background technology

Traditional indoor and outdoor illumination adopts incandescent lamp or electricity-saving lamp usually, but their relative energy consumptions are higher.Along with the progress of electronic technology, LED because of its long in life-span, wavelength can be selected because of purposes, easy to make, operating cost is low, power consumption is little and non-environmental-pollution is widely used, and LED also progressively becomes the emerging light source that substitutes the traditional lighting light source.

Characteristics such as the LED volume is little, luminous efficiency is high, power saving make it be used widely at lighting field, mainly comprise: signal light path, demonstration backlight, auto lamp, full color display etc.And these application are all relatively strict to the requirement of LED lighting angle, otherwise can influence the practical function of product.The luminescent panel of producing led light source at present all is a planar structure; Because LED has one-way; Press the luminous characteristics of certain angle, make the light fixture of its formation in application process, have problems such as rising angle is little, light beam is too concentrated, wide-angle property is relatively poor, thereby influence the range of exposures of light source.

The utility model content

The purpose of the utility model is to overcome shortcoming of the prior art with not enough, and a kind of LED light fixture that increases rising angle is provided.

In order to achieve the above object, the utility model is achieved through following technical proposals: a kind of LED light fixture comprises the pedestal and the LED luminescence chip that are used for fixing the LED luminescence chip; It is characterized in that: described pedestal is the truncated rectangular pyramids shape, and its upper surface is the square or rectangular plane, and four sides are the domatic of isosceles trapezoid; Said LED luminescence chip is distributed on the upper surface and four sides of pedestal, and is electrically connected with power supply.

In order to realize the utility model better, said LED light fixture also comprises the FPC on the upper surface that sticks to said pedestal and four sides, and the FPC coverage rate is wider, is convenient to lead layout and welding; Said LED luminescence chip is distributed on the FPC and is electrically connected with it, and said FPC is electrically connected with power supply.

The said quantity that is distributed in the LED luminescence chip on pedestal upper surface and four sides equates that such distribution makes that the bright dipping of all directions is more even.

Said being distributed in electrically connecting as series, parallel or series-parallel connection between the LED luminescence chip on the one side, to be applicable to different use occasions and mode.

Said LED light fixture also comprises the lampshade of transparent hemispheroidal lampshade or transparent cylinder, and said pedestal and LED luminescence chip all are arranged in the lampshade.

Said LED light fixture also comprises the lamp holder that is connected with power supply, and the model of said lamp holder is G9 or GU10 or G5.3.The model of lamp holder is by IEC (International Electrotechnical Commission) standard formulation.The lamp holder that this LED fitting structure can be joined multiple model uses.

Described pedestal is the metal or alloy pedestal, because metal metallic aluminium particularly is widely used because of its heat conductivility is high.

Compared with prior art; The utlity model has following advantage and beneficial effect: the utility model is through changing the base construction of fixed L ED luminescence chip; Existing pedestal is changed into the structure of truncated rectangular pyramids by planar structure; Thereby increased the rising angle of the light fixture of application of LEDs luminescence chip, enlarged the range of exposures of this light fixture, made the application of LED light fixture more extensive.
