Double-face light emergent slice type light emitting diode (LED) lamp

Abstract

The invention discloses a double-face light emergent slice type light emitting diode (LED) lamp, which comprises a lamp holder, a power supply and a transparent lampshade, wherein the power supply is arranged in the lamp holder. The lamp is characterized by also comprising an LED lamp source and a lamp core clamp, wherein the lamp core clamp is arranged in the transparent lampshade; a gap is reserved in the lamp core clamp; the LED light source is arranged in the gap of the lamp core clamp, is conducted by the power supply in the lamp holder, and comprises a flexible circuit substrate; and a plurality of LED chips or packaged LED lamp beads are directly attached to two faces of the flexible circuit substrate. The problems of poor heat dissipation effect, relatively short service life and relatively heavy weight of the conventional LED lamp, the problem that the conventional LED lamp is easy to damage and the problems of relatively low light emergent efficiency and relatively low light source utilization rate because only a single face of the conventional LED light source emits light are solved; due to the double-face light emergent slice type LED lamp, the light emergent efficiency and the light source utilization rate are improved; furthermore, the heat dissipation capacity of a luminous light source of the LED lamp is improved greatly, and the weight and the cost of the LED lamp are reduced; and the double-face light emergent slice type LED lamp is more suitable for automatic production, and is supplied to consumers for use.

Description

technical field [0001] The invention belongs to the technical field of LED lampshades, and in particular relates to a double-sided light-emitting sheet-type LED lamp. Background technique [0002] Since light-emitting diodes are high-efficiency cold light-emitting elements that can convert electrical energy into light energy, and have the advantages of low power consumption and long life, light-emitting diodes are mostly used for indication purposes in electronic products. However, the power of some LED lamps in use is relatively large, and the life of the LED light source is closely related to the operating temperature of the node. At present, only about 50% of the electric energy of the LED lamp is converted into light energy during the working process, and the rest of the electric energy is almost Converted into heat energy, the temperature of the LED lamp increases, and its reliability will be reduced by half for every 10 degrees Celsius increase in temperature.

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems of poor heat dissipation, easy damage, short service life and heavy weight of LED lights in the prior art, at the same time, the LED light source emits light from one side, the light output efficiency is poor, and the light source utilization rate is low. Surface-emitting sheet-type LED lights improve light output efficiency and light source utilization, greatly improve the heat dissipation capacity of LED light sources, and reduce the weight and cost of LED lights. They are more suitable for automated production and are used by consumers.
