Problems solved by technology

However, LED lights generate high heat at the same time of high brightness. The chip temperature of LED lights must be below 80 degrees Celsius to convert electrical energy into light energy instead of heat energy. Emission will cause the light-emitting diodes to burn out, affect the service life, and increase the cost of use
[0003] Traditional LED advertising lights only emit light from one side, and then rely on the reflective layer to reflect, so they cannot achieve full 360-degree light emission, and the irradiated light is not uniform enough. long

Abstract

The invention discloses a light-emitting diode (LED) advertising lamp. The LED advertising lamp comprises a strip-shaped lamp tube, lamp caps, an I-shaped aluminum strip, aluminum substrates and LED chips, wherein the lamp caps are arranged at the two ends of the lamp tube; the lamp caps are provided with plugs to be in butt joint with external power sockets; the aluminum substrates are arranged on both sides of the I-shaped aluminum strip; the LED chips are fixed to the aluminum substrates; the I-shaped aluminum strip and the aluminum substrates are sleeved with rubber rings at intervals; andthe aluminum substrates are also provided with current-limiting resistors. In the LED advertising lamp of a novel structure, the I-shaped aluminum strip is matched with an aluminum profile, and the LED chips are arranged, so that the LED advertising lamp is simple in structure, is large in light-emitting angle, is fixed firmly, and is adjustable in light-emitting angle.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED advertising lamp. Background technique [0002] Light-emitting diodes (that is, LEDs) are widely used as light sources in the fields of lighting fixtures and electronic devices due to their advantages of high brightness, low power consumption, and long service life. However, LED lights generate high heat at the same time of high brightness. The chip temperature of LED lights must be below 80 degrees Celsius to convert electrical energy into light energy instead of heat energy. Emission will cause the light-emitting diodes to burn out, affect the service life, and increase the cost of use. [0003] Traditional LED advertising lights only emit light from one side, and then rely on the reflective layer to reflect, so they cannot achieve full 360-degree light emission, and the irradiated light is not uniform enough. long. Contents of the invention [0004] The object of the present i...
