Abstract

The utility model relates to an LED structure, which comprises anode and cathode metal supports, a luminous chip, fluorescent powder, a positive gold wire and a negative gold wire. The luminous chip and the fluorescent powder are supported inside a cup of the cathode metal support, the depth from the upper surface of the luminous chip to the surface of the cup is 0.45mm-0.55mm, and the mouth of the cup flares outward at an angle of 53.5-56.5 degrees. The LED structure can achieve the highest brightness of LEDs, simultaneously enables uniformity of emitted light to be identical, and increases yield rate of products.

Description

A kind of LED structure

Technical field

The utility model relates to a kind of structure of LED light-emitting diode, the particularly a kind of LED of raising luminosity and the LED structure that light is evenly dispersed.

Background technology

LED as the 4th generation light source, have low power consuming, environmental protection, multiple advantages such as the life-span is long, and will replace incandescent lamp and fluorescent lamp gradually as energy-efficient light source, its application prospect is boundless, whole world all big enterprises are all in development and exploitation.

And at present the light that sends of common LED is inhomogeneous, thereby makes shaded portion around the hot spot that emits, and causes losing of brightness aspect, influences visual effect.

The utility model content

The utility model provides a kind of LED structure at the above-mentioned defective of prior art, so that the outstanding center brightness of the hot spot that comes that sends the time, and the high conformity of hot spot, the dash area of having removed around the hot spot makes its hot spot even.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of LED structure, comprise the two poles of the earth metallic support, luminescence chip, fluorescent material, positive and negative gold thread, luminescence chip, fluorescent material are carried in the cup on the cathodic metal support, and described luminescence chip upper surface is 0.45～0.55mm to a cup face degree of depth, and rim of a cup is 53.5～56.5 ° of angles and opens.

Preferably, solder joint exceeds glass face a 0.13～0.18mm on the support of described the two poles of the earth.

Preferably, described luminescence chip upper surface is 0.5mm to the cup face degree of depth, and rim of a cup is 55 ° of angles and opens.

Preferably, rim of a cup is provided with the lead foot to the cup sunken inside on every side.

As can be seen from the above technical solutions, the dark 0.5mm of the utility model cup is 55 degree angles and opens, and this degree of depth and angle meet light refraction and principle of reflection, when can reach maximum brightness, make the light uniformity unanimity that emits.Further, solder joint height is 0.13～0.18mm, and this highly mainly is for the radian of getting to more than the solder joint at the bottom of the cup when gold thread reaches optimum efficiency, prevents that gold thread from breaking, and improves yield of products.The utility model has been done a lead foot to the cup sunken inside around the rim of a bowl, rather than to rim of a cup processings of clapping, the advantage that makes it have bat the rim of a bowl support and not clap the rim of a bowl support rim of a cup

Fig. 2 is the utility model led chip position detailed structure view.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail.

Referring to Figure 1 and Figure 2, a kind of LED structure provided by the utility model comprises that cathode metal support 2, negative pole metallic support 1, negative pole support 1 top are provided with a glass groove, luminescence chip 3 and fluorescent material 4 are carried in the cup, luminescence chip 3 upper surfaces are 0.45～0.55mm to the cup face degree of depth, and rim of a cup is 53.5～56.5 ° of angles and opens.

As preferred implementation of the present utility model,

solder joint

11 and 21 exceeds glass face a 0.13～0.18mm on described positive pole and the negative pole support.

As preferred implementation of the present utility model, the luminescence chip upper surface is 0.5mm to the cup face degree of depth, and rim of a cup is 55 ° of angles and opens.

As preferred implementation of the present utility model, done a lead foot around the rim of a bowl to the cup sunken inside, rather than to playing a rim of a cup processings of clapping, the advantage that makes it have bat the rim of a bowl support and not clap the rim of a bowl support rim of a cup.

Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail this creation, for people's bodyguard of being familiar with this type of skill, according to the above description, may do partly change and modification to this specific embodiment, its essence does not detach the spiritual category person of this creation, all should be included in the claim of this case.

Claims
