LED (light emitting diode) outdoor lamp light assembly

Abstract

The invention discloses an LED (light emitting diode) outdoor lamp light assembly which comprises a radiator, an LED lamp plate and a combined type lens, wherein the radiator is composed of a bottom plate and fins which are integrally formed; the bottom plate is provided with gaps, the fins are arranged on the back of the bottom plate at intervals and extend to the gap to form a channel which can ventilate vertically; the combined type lens and the LED lamp plate are arranged on the frontage of the bottom plate, and the LED lamp plate is placed in the combined type lens; the combined type lens and the frontage of the radiator bottom plate form a tight connection through a water-proof silica gel loop, an IP dust-proof water-proof level achieves more than 67, the combined type lens has multiple optical curved surfaces, and each curved surface is corresponding to an LED lamp bead on the lamp plate; and the function of the curved surfaces is to change the light intensity spatial distribution of light emitted by the LED lamp beads into the light intensity spatial distribution which is suitable for illumination for a road surface, namely light distribution. The invention aims to provide an LED outdoor lamp light assembly which has the advantages of good heat dissipation and low failure rate, and the light assembly can be arranged in a shell of a street lamp and be connected with a power source, thereby forming an LED street lamp.

Description

technical field [0001] The invention relates to an LED outdoor lighting fixture, in particular to a light component of an LED outdoor lighting fixture. Background technique [0002] Outdoor lighting fixtures generally include street lights, tunnel lights, high pole spotlights, floodlights, stadium spotlights, billboard spotlights and garden lights, etc., because of high power, high power consumption, and the setting height Higher, it is not convenient for frequent replacement and maintenance. Generally, high-pressure sodium lamps or metal halide lamps with longer service life and higher luminous efficiency are selected as light sources. However, compared with LED outdoor lamps, the energy-saving coefficient of high-pressure gas discharge lamps such as high-pressure sodium lamps or metal halide lamps is still very low. However, its light is 360° around, and after adjusting the direction of light through the reflector, the light loss is as high as 40%; The light is imprecise...

AI Technical Summary

Problems solved by technology

[0006] LED outdoor lighting fixtures are installed outdoors, so LED outdoor lighting fixtures must often face the sun and rain, so it is particularly important to ensure the waterproofness of LED outdoor lighting fixtures; and not only waterproof, but also moisture-proof and water-proof, because as long as If water vapor enters the sealed cavity where the LED lamp beads are installed, it will damage the LED packaging materials and chips, causing the LED lamp beads to decay or even die.
