LED bulb

Abstract

The invention discloses an LED bulb. The LED bulb comprises a lamp holder, a heat dissipation base, a connecting part, a cross light-emitting panel and a lamp shade, wherein LED lamps are mounted on the cross light-emitting panel; in addition, LED lamps are mounted on the connecting part for light distribution, so that the luminous brightness of the whole bulb is higher, and 320-degree lighting is realized; and the size of the heat dissipation base can be adjusted according to the quantity of the LED lamps so as to enable the radiating effect of the heat dissipation base to be matched with the watt level of the bulb. Compared with a lamp with the same power, such as an energy-saving lamp, a sodium lamp and a halogen lamp, the brightness of the LED bulb can be improved by 60-80 percent; and as the LED bulb does not contain mercury, lead and other poisonous substances, as well as infrared rays and ultraviolet rays, so that environmental pollution is prevented.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a cross refraction light-emitting LED light bulb. Background technique [0002] LED is a semiconductor that can convert electrical energy into light energy. It changes the principle of tungsten filament luminescence of incandescent lamps and the three-based toner luminescence of energy-saving lamps, and uses electric field luminescence. The characteristics of LED are very obvious, such as long life, high luminous efficiency, low radiation and low power consumption. The spectrum of white LEDs is almost entirely concentrated in the visible light band, and its luminous efficiency can exceed 150lm / W (2010). [0003] Comparing LEDs with ordinary incandescent lamps, spiral energy-saving lamps and T5 tricolor fluorescent lamps, the results show that: the luminous efficacy of ordinary incandescent lamps is 12lm / W, and the service life is less than 2000 hours; the luminous efficacy of spiral energy-...

AI Technical Summary

Problems solved by technology

[0005] Existing LED lamp panels have the problem that a single light-emitting surface is relatively narrow. If multiple LEDs are integrated on a circuit board on a large scale to form a relatively large light source, the technical problem of insufficient brightness of a single LED lamp will be solved. It will cause a lot of heat to accumulate, and sometimes it will break down the circuit board, so the heat dissipation problem of LED lights is another technical problem that needs to be solved
