Description

A kind of high optically focused LED

Technical field

The utility model relates to light sources technical field more particularly to a kind of LED light sources.

Background technique

LED is a kind of semiconductor electronic component that can convert electrical energy into luminous energy, and LED lamp bead is small in size, light-weight, is used Service life is long, and energy conservation and environmental protection, application is more and more extensive, but at this stage, the optical power of single led wick is lower and light emitting angle compared with Greatly, it is unable to satisfy the occasion for needing optically focused.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of high optically focused LED, which has hair Angular is small, and light beam is gathered, the good feature of thermal diffusivity.

The utility model solves technical solution used by its technical problem are as follows:

A kind of high optically focused LED, including the substrate, refractive body and fluorescent film set gradually from bottom to top, on the substrate Centre of surface is equipped with flip-chip, and the flip-chip is wrapped in refractive body, be equipped in the substrate positive terminal pad and Negative terminal pad, the positive terminal pad and negative terminal pad weld with flip-chip respectively and stretch out base lower surface.

As an improvement of the above technical solution, the substrate is cube, and refractive body is hemisphere, and refractive body is arranged in substrate Upper surface center.

As an improvement of the above technical solution, the fluorescent film be bonded in refractive body upper surface and substrate except refractive body with Outer region.

As an improvement of the above technical solution, the positive terminal pad and negative terminal pad are respectively arranged at a left side for base lower surface Right both ends.

As an improvement of the above technical solution, the positive terminal pad and negative terminal pad are cube.

As an improvement of the above technical solution, the refractive body is made of transparent silica gel.

The beneficial effects of the utility model have:

This LED, upper surface of base plate center are equipped with flip-chip and refractive body, and flip-chip is wrapped up by refractive body, refractive body It is equipped with fluorescent film, since the refractive index of refractive body, fluorescent film and air to light is different, the light warp of flip-chip transmitting After superrefraction, the direction for scattering light is deviated toward the same direction, that is, produces spotlight effect, and this LED structure is simple, production side Just.

Detailed description of the invention

With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, in which:

Fig. 1 is the structural schematic diagram of the utility model embodiment；

Fig. 2 is the bottom view of the utility model embodiment.

Specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of high optically focused LED of the utility model, including substrate 1, the folding set gradually from bottom to top Body of light 2 and fluorescent film 3.The substrate 1 is cube, and 1 upper surface center of substrate is equipped with flip-chip 4.The refractive body 2 is arranged Centre of surface on substrate 1, refractive body 2 are made of transparent silica gel, are in hemisphere, and flip-chip 4 is wrapped in refractive body 2 It is interior.

The fluorescent film 3 is bonded in the region of the upper surface and substrate 1 of refractive body 2 in addition to refractive body 2, due to refractive body 2, fluorescent film 3 and air are different to the refractive index of light, and the light that flip-chip 4 emits dissipates after the refraction of refractive body 2 The direction for penetrating light is deviated toward the same direction, that is, produces spotlight effect.

It is equipped with positive terminal pad 6 and negative terminal pad 5 in the substrate 1, the positive terminal pad 6 and negative terminal pad 5 are Cube, positive terminal pad 6 and negative terminal pad 5 stretch out the left and right sides of 1 lower surface of substrate, and weld respectively with flip-chip 4.This Foreign current is tapped into flip-chip 4 by positive terminal pad 6 and negative terminal pad 5 by LED, so that flip-chip 4 be made to shine.It will be positive Pad 6 and negative terminal pad 5 are used as tie point, can be welded on this LED on various circuit boards and form integrated optical source.

The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, all should belong to the utility model Protection scope.
