Abstract

The invention relates to a bulb and discloses a light-emitting diode (LED) bulb, which comprises a lamp holder, a power module and a light source chip which are electrically connected in turn, and is characterized by also comprising an upper cover, a radiator and a lampshade which are fixedly connected in turn, wherein the lamp holder is fixedly connected with the top of the upper cover; the power module is fixed on the top surface of the radiator; the light source chip is fixed on the bottom surface of the radiator; the top of the lampshade is provided with a through hole; a cylinder is arranged in the circumferential direction of the through hole; the bottom of the cylinder is provided with a lens opposite to the light source chip; the top of the cylinder is in sealed connection with the bottom surface of the radiator; and the radiator consists of a cylinder and vertical strip radiating fins distributed on the outer wall of the cylinder. The LED bulb has the characteristics of good radiating effect, proper chip position installation, high secondary light emitting efficiency, attractive and elegant appearance, convenience for production, low cost and suitability for promotion and application.

Description

technical field [0001] The invention relates to a light bulb, in particular to an LED bulb type light bulb. Background technique [0002] LED is the abbreviation of Light Emitting Diode in English, and it is translated as "light emitting diode" in Chinese. It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine and release excess energy. Photon emission produces visible light. LED is an electronic device with diode characteristics that can convert electrical energy into light energy. Different light-emitting diodes can emit light of different wavelengths from infrared to ultraviolet light. LED light sources have high luminous efficiency. At present, the luminous efficacy of high-power LEDs can reach 140 lumens / watt, and the long-term development can reach 150-200 lumens / watt. Efficiency is 50-70 lumens / watt, sodium lighting effect is 90-140 lumens / watt, and most of the rest...
