Embodiment Construction

[0023] The present invention will now be explained in detail with reference to the accompanying drawings.

[0024] 1-11, according to an embodiment of the present invention, the floodlight 100 mainly includes three parts, namely a base 110, a light emitting module 130 installed in the base 110 and connected with the base 110 so that the light emitting module 130 is fixed on the upper cover 150 in the base 110 .

[0025] Referring to FIGS. 1-5 , the base 110 has a cylindrical shape as a whole, and includes a bottom 112 and an annular sidewall 114 bent and extended from the bottom 112 . An accommodating space 116 is defined between the bottom 112 and the annular sidewall 114 for accommodating the above-mentioned light emitting module 130 . The bottom 112 is provided with a power wire through hole 119 through which the power wire passes, a signal wire through hole 162 through which the signal wire passes through, and a receiving hole 163 . A first stepped portion 118 is formed ...

Abstract

The invention provides a spot lamp which comprises a base seat, a light emitting module installed in the base seat and an upper cover which is connected with the base seat to provide convenience for installing the light emitting module in the base seat, wherein, the base seat comprises a bottom part and annular side walls which are bended and extended from the bottom part; the light emitting module is held in a holding space defined by the bottom part and the annular side walls and at least comprises a lamp bead tray and a lamp bead plate which is supported in the lamp bead tray; reinforcing ribs used for increasing the strength of the base seat are arranged on external walls of the annular side walls; and the periphery of the bottom part takes the shape of a ring with round angles and a heat sink strip used for dissipating heat is arranged on the lamp bead tray. The spot lamp has good performance of heat dissipation and firm and safe structure.

Description

technical field [0001] The invention relates to stage lighting equipment, in particular to a light-projection type waterproof functional lamp. Background technique [0002] Flood light equipment is widely used in large-scale performance venues, such as square lighting, studios, etc., to provide the required lighting for performance venues and outdoor lighting projects. A typical floodlight structure includes a shell-shaped base, a light-emitting module set in the shell-shaped base, and an upper cover combined with the shell-shaped base to fix the light-emitting module in the base. A light emitting module usually includes a switching power supply, a lamp bead tray, a lamp bead board, and an optical lens assembly that are assembled together. Wherein, the lamp bead board is provided with a light-emitting element, that is, a light-emitting diode, and the lamp bead board is placed in the lamp bead tray. When the switching power supply supplies power to the light-emitting diodes...
