Abstract
The utility model relates to the LED light emission technical field, in particular to an improved structure of a novel monochromatic LED displayer, comprising an LED chip and a carrier which is provided with a groove; the LED chip is positioned at the bottom of the groove which is filled with at least upper and layer two layers of transmit resin which are of different indices of refraction; as the upper and lower two layers of transmit resin are different in index of refraction, the light rays emitted by the LED concentrated in the center to increase the brightness of the LED after refracted by the two layers of transmit resin, provided the index of refraction of the upper layer of transmit resin is larger than that of the lower layer of transmit resin; while the light rays emitted by LED is diverged in all direction after being refracted by the two layers of transmit resin to enlarge the light emitting angle of the LED, provided the index of refraction of the upper layer of transmit resin is small than that of the lower layer of transmit resin.
Description
Technical field:
The utility model relates to LED luminescence technology field, refers in particular to a kind of structure-improved of novel monochromatic LED display.
Background technology:
At present, traditional light-emitting diode display primary structure comprises led chip and carrier, carrier offers groove, led chip is positioned at bottom portion of groove, be filled with light-transmissive resin in the groove, the light that LED sends is outwards emission after the light-transmissive resin refraction, because the refractive index of light-transmissive resin is fixed, so the brightness and the dispersion angle of the LED light after refraction are constant, but wishing the brightness of light-emitting diode display, some user can increase, some user wishes that then the divergence of beam angle of light-emitting diode display increases, so traditional light-emitting diode display can't satisfy different users's demand.
The utility model content:
The purpose of this utility model is exactly the structure-improved that a kind of novel monochromatic LED display is provided at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: it comprises led chip and carrier, and carrier offers groove, and led chip is positioned at bottom portion of groove, is filled with the light-transmissive resin of upper and lower at least two-layer different refractivity in the groove.
The carrier bottom also is provided with metal pins, and metal pins is connected with led chip.
After adopting said structure, because the refractive index of the upper and lower two-layer light-transmissive resin in the groove is inequality, when the refractive index of upper strata light-transmissive resin during greater than the refractive index of lower floor's light-transmissive resin, the light that LED sends is concentrated to central authorities through two-layer light-transmissive resin refraction back, the brightness that can improve LED; When the refractive index of upper strata light-transmissive resin during less than the refractive index of lower floor's light-transmissive resin, the light that LED sends is after two-layer light-transmissive resin refraction, and light scatters towards periphery, and it is big that the LED emission angle becomes.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
See shown in Figure 1ly, the utility model comprises led chip 1 and carrier 2, and carrier 2 offers groove 3, and led chip 1 is positioned at groove 3 bottoms, is filled with the light- transmissive resin 4,5 of upper and lower two-layer different refractivity in the groove 3.When the refractive index of upper strata light-transmissive resin during greater than the refractive index of lower floor's light-transmissive resin, the light that LED sends is concentrated to central authorities through two-layer light-transmissive resin refraction back, the brightness that can improve LED; When the refractive index of upper strata light-transmissive resin during less than the refractive index of lower floor's light-transmissive resin, the light that LED sends is after two-layer light-transmissive resin refraction, and light scatters towards periphery, and it is big that the LED emission angle becomes.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model patent claim.
