Floodlight

Abstract

The invention relates to a floodlight which comprises a lamp holder and a supporting device. The lamp holder comprises a lamp holder front casing, a transparent piece, a sealing ring, an aluminum substrate, a lamp holder back casing and a first locking ring. A first snap ring portion is arranged on the lamp holder front casing, a first groove ring portion is arranged on the lamp holder back casing in a fitted mode, and the first locking ring is movably arranged, surrounds the first snap ring portion and adjusts a self locking state. A plurality of radiating grooves are arranged on the back face of the aluminum substrate, the front face of the aluminum substrate is polished, a plurality of floodlight light-emitting diodes (LEDs) are annularly arranged on the front face of the aluminum substrate, and the sealing ring and the transparent piece are sequentially arranged on the lamp holder front casing in a pressed mode through the front face of the aluminum substrate. A plurality of cable through holes and a plurality of connection end portions are respectively arranged on the front face of the aluminum substrate, each cable through hole is respectively used for passing through each cable on the outside, and each connection end portion is respectively connected with the corresponding cable. The lamp holder back casing enables the aluminum substrate, the sealing ring and the transparent piece to be fixed on the lamp holder front casing through a plurality of bolts. A plurality of radiating holes are arranged in a shape of a concentric circle. By means of the technical scheme, the floodlight is good in sealing performance, good in radiating performance, light and handy in structure, convenient to carry and good in floodlight performance.

Description

【Technical field】 [0001] The invention relates to an LED lighting fixture, in particular to a floodlight. 【Background technique】 [0002] The existing LED floodlight is a point light source that can irradiate evenly in all directions. Its irradiation range can be adjusted arbitrarily. Under low current, the temperature rise of the LED floodlight is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the light will deteriorate. Moreover, the existing LED floodlight has a large volume and is inconvenient to carry. [0003] Therefore, the prior art needs to be improved. 【Content of invention】 [0004] In view of this, it is necessary to propose a novel floodlight. [0005] A technical solution of the present invention is a floodlight, which includes a lamp cap and a supporting device; wherein, the lamp cap includes a lamp cap front shell, a tr...

[0002] The existing LED floodlight is a point light source that can irradiate evenly in all directions. Its irradiation range can be adjusted arbitrarily. Under low current, the temperature rise of the LED floodlight is not obvious

If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the light will become worse.

Moreover, the existing LED floodlights are large in size and inconvenient to carry
