Integrated type LED floodlight lamp

Abstract

The invention discloses an integrated type LED floodlight lamp, which comprises a shell, end covers, a light-transmitting panel, an LED light source, an LED power supply, a driving control circuit, a reflection device and an installation support, wherein the shell is arranged on the installation support; the end covers are clamped at both ends of the shell, the light-transmitting panel is clamped at the upper end of the shell, and the shell, the end covers and the light-transmitting panel form a seal space through combination; the LED light source is fixedly arranged on the inner wall of the shell; the LED power supply and the driving control circuit are arranged on the inner walls of the end covers or outside the lamp; the reflection device is arranged at the position opposite to the light source on the inner wall of the shell; and the LED power supply and the driving control circuit are electrically connected with the LED light source and have no thermal contact with the LED light source. The integrated type LED floodlight lamp has the advantages of no glare, uniform light distribution, high-efficiency heat-dissipating effect, low energy consumption, long service life, small attenuation of light energy, low production cost and simple machining.

Description

technical field [0001] The invention relates to a lighting appliance, in particular to an integral LED floodlight. Background technique [0002] Traditional floodlights mostly use high-power (about 100W) tungsten lamps, mercury lamps, iodine-tungsten lamps or high-pressure sodium lamps as light sources, which are large in size, heavy in weight, high in energy consumption, high in maintenance costs, and seriously pollute the environment. Unsatisfactory. [0003] In 1965, the world's first commercial light-emitting diode (LED) was born. With the continuous advancement of technology, LED has developed rapidly. In recent years, the luminous efficiency of LEDs of certain colors has greatly exceeded that of incandescent lamps, and even reached that of fluorescent lamps. efficiency. Compared with the traditional electric light source of floodlight, LED light source is basically non-toxic, non-electromagnetic pollution, and has many advantages such as small size, low energy consum...

AI Technical Summary

Problems solved by technology

[0004] 1. Considering the lack of luminous brightness of a single LED, LED lamps generally adopt an LED array structure, resulting in concentrated heat and high local temperature of LED lamps, resulting in unstable circuit control system, excessive energy consumption, and reduced lamp life And other issues,

[0005] 2. Since LED is a linear light source, generally LED lamps use lenses or other light management devices to change their light distribution requirements, resulting in excessive glare and uneven light distribution, which cannot meet the required requirements

Although this split design method reduces the influence of LED light source heating on electrical components, it brings inconvenience to cost control and lamp installation.

[0009] In Chinese Patent Application Publication Nos. CN1767815Y and CN2886319Y, each discloses a linear LED floodlight. In these two solutions, the LED light source and the electrical device are spatially isolated, but no heat dissipation structure is designed. Therefore, Heat deposits inside the body, the influence of LED light source heat on electrical components still exists, and the power consumption, stability, and service life of lamps will still be affected.

[0010] In the Chinese Patent Application Publication No. CN1760585A document, an LED lamp is disclosed, which places electrical components in a sealed cavity filled with heat-conducting insulating liquid to separate the electrical components from the LED light source. Although this method can effectively achieve heat dissipation and isolation , but the production cost is too high, processing and maintenance are extremely inconvenient, and it is not suitable for extensive production at this stage
