LED light projecting lamp

Abstract

The invention relates to an LED flood light, comprising a strip-shaped radiating piece, a luminescence component fixed in the radiating piece and a lampshade sheathed at the periphery of the radiating piece, the luminescence component comprises an LED light and an aluminum base plate which is used to fix the LED light, a photospot is sheathed at the front end of every LED light, the radiating piece is provided with a longitudinal groove, the LED lights are flat stuck at the bottom part of the groove and are slantingly arranged at two edges of the groove. By renovating the structure of the LEDflood light and by grouping three or more than three luminescence components which are slantingly arranged in the groove of the radiating piece, the LED flood light improves the utilization rate of light and saves electric energy, in addition, a plurality of luminescence components emit mutually overlapped and supplemented light, thus ensuring better uniformity of light.

Description

technical field [0001] The invention relates to an illuminating device, more precisely, an LED floodlight lamp. Background technique [0002] In the existing various lighting occasions such as billboards, signboards, blackboards and building night scenes, a large number of floodlights are used. With the maturity of high-power LED lamp technology, LED lamps are characterized by energy saving, environmental protection and long life. Features are increasingly favored by people. LED floodlights are also increasingly valued by people. In the existing structure of LED floodlights, LED lights are generally arranged linearly on a plane, and light-transmitting components with a single beam angle are used. LED floodlights with this structure have the following defects: [0003] 1. Low utilization rate of light. In order to make the light distribution uniform, it can only be far away from the object to be illuminated. According to the principle that the illuminance is inversely pro...

AI Technical Summary

Problems solved by technology

According to the principle that the illuminance is inversely proportional to the square of the distance, increasing the distance can only significantly reduce the illuminance of the illuminated surface, which indirectly wastes electric energy;

[0004] 2. The installation of the lamp is not reliable, and the light is easy to deviate from the normal direction

Due to technical and other reasons, the existing LED floodlights need to be composed of multiple lights or light strips to form a lighting system, and the shooting direction adjustment mechanism is easy to fail and change direction, causing individual lamps to deviate from the normal shooting direction;

[0005] 3. Poor light uniformity

The existing pear-shaped symmetrical light distribution has a large light drop, resulting in a large difference in brightness of the illuminated surface, that is, poor light uniformity, while the light intensity ratio of the reflector-type asymmetrical light distribution on the upper and lower sides is below 1.5 / 1, reaching Less than a reasonable 2.5-3 / 1, it can only be compensated by extending the distance, resulting in waste of light and electricity;

[0006] 4. Installation is inconvenient and affects the appearance of the object to be illuminated

Due to the large size of the existing LED floodlights, it is inconvenient to install and conceal, which affects the overall appearance of the illuminated object;

[0007] 5. Prone to broken glass

Due to waterproofing, hard glass is required to transmit light, and the glass is often broken for various reasons, resulting in failure of the lamp function and personal injury
