Abstract
The utility model discloses an LED (light-emitting diode) package lamp which comprises a base (1), an optical lens (3) and an LED chip (4). The LED package lamp is characterized in that the LED chip is connected to a base seat, a silicone layer (2) is arranged on the LED chip and completely covers the LED chip, a lens (5) covers the outside of the silicone layer (2) and is a ceramic optical lens with a high refractive index, the refractive index of the lens is larger than 1.5, the silicone layer is made of silicone with a high refractive index, the refractive index of the silicone layer is larger than 1.4, the optical lens (3) has a high refractive index, and the refractive index of the optical lens (3) is larger than 1.4. The LED package lamp is improved in terms of package technology, so that light paths generated by the LED chip increase the refractive index, the light-emitting efficiency of LEDs is improved, display quality is improved, and light passing effects are improved.
Description
Technical field
The utility model relates to a kind of LED encapsulation technology, relates in particular to a kind of LED packaging lamp.
Background technology
Along with the LED technology develops rapidly, LED almost has application at industry-by-industry, and progressively replace conventional light source, the LED encapsulation technology is also in continuous progress, and the incandescent light bulb luminous efficiency is low, by the LED light fixture, is substituted gradually, LED development along with technology is first arranged, people require more and more higher to its lighting effect, and the luminous efficiency of LED bulb is not high at present, and logical light effect is weakened.
The utility model content
The defect existed in order to overcome above-mentioned prior art, the utility model provides a kind of New LED packaging lamp, on encapsulation technology, is improved, make the light path that LED chip produces increase refractive index, thereby improve the light extraction efficiency of LED, improved display quality, more carry logical light effect.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of LED packaging lamp, comprise matrix (1), optical lens (3), LED chip (4), its described LED chip is connected in base seat, layer of silica gel (2) is set on LED chip, layer of silica gel covers LED chip fully, the outer lens (5) that are covered with of described layer of silica gel (2).
The described lens of further described LED packaging lamp (5) are the high index ceramic optical lens, and its refractive index is greater than 1.5.
The described layer of silica gel of further described LED packaging lamp is high index of refraction silica gel, and its refractive index is greater than 1.4.
The described optical lens of further described LED packaging lamp (3) is the high index of refraction optical lens, and its refractive index is greater than 1.4.
The described optical lens of further described LED packaging lamp (3) is the glass optical lens.
The beneficial effects of the utility model: through increase the high index of refraction layer of silica gel on LED chip, and the lens of high index of refraction, and the refractive index of increase optical lens, thereby improve the path of light, reach the light extraction efficiency that improves LED, improved display quality, more carry logical light effect.
The accompanying drawing explanation
Fig. 1 is the described LED packaging lamp of the utility model embodiment texture edge schematic diagram.
The specific embodiment
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of LED packaging lamp, comprise matrix (1), optical lens (3), LED chip (4), its described LED chip is connected in base seat, layer of silica gel (2) is set on LED chip, layer of silica gel covers LED chip fully, the outer lens (5) that are covered with of described layer of silica gel (2), the pedestal of LED light fixture is equipped with electrode cable etc. in (1), above-mentioned electrode cable is connected to LED chip, LED chip adopts the elargol die bond, the outer layer of silica gel of LED chip simple for production is high index of refraction silica gel, its refractive index is greater than 1.4, lens (5) are the high index ceramic optical lens, its refractive index is greater than 1.5, described lens material also can select high thermal conductivity coefficient pottery or or epoxy resin or glass make, in the process of packaging silicon rubber layer, can nanometer or the Air nano particle of high thermal conductivity coefficient will be added in silica gel, thereby further optimize the function of LED light fixture.
The utility model is not limited to the true mode of above-mentioned the best; anyone can draw the various forms product under enlightenment of the present utility model; returned and improved and change at the prerequisite the utility model that does not break away from the utility model spirit and scope, these improve and change and all fall in claimed the utility model scope.
