Hand-held LED lighting device

Abstract

The invention relates to a hand-held LED lighting device, which comprises a sealed shell, wherein the sealed shell is formed by fixedly connecting a front shell and a rear shell, and a flood light source component is fixedly arranged at a light passing area of the front shell; a condensing light source component, wherein the condensing light source component is arranged at the opening of the top of the rear shell; a radiating device, wherein the radiating device comprises a radiating fin and an axial flow fan, wherein radiating fins are fixedly arranged in the sealed shell, the axial flow fanis fixedly arranged at the inner side of the rear shell, corresponding to the position of the axial flow fan, and the rear shell is provided with a ventilation opening; a battery, wherein the batteryis arranged in the sealed shell to supply power for each electric device; a control device, wherein the control device comprises a controller and a light source circuit board, wherein the controller and the light source circuit board are arranged in the sealed shell; the light source circuit board is provided with a constant current driving circuit; the controller drives the condensing light source component or the flood light source component to work through the constant current driving circuit, the controller also charges the battery through a charging management circuit arranged on the light source circuit board; the controller also controls the opening or closing of the axial fan.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to a hand-held LED lighting device. Background technique [0002] LED lamp is an electric light source. When electrons pass through a semiconductor chip encapsulated in epoxy resin, negatively charged electrons and positively charged holes on the chip recombine and disappear while generating photons. The traditional incandescent and fluorescent lamps used in the auto maintenance industry are fragile and have low waterproof rating, so they cannot be used outdoors. [0003] The existing hand-held tool lamp cannot combine the size and power. The existing product is 1000lm, the total power of the product is 9W, and the product is a constant current design, which means that the power is constant at 9W. The heat output per minute of this power product is 350 joules, the product size is 150*57*24mm. Since the existing product is a hand-held aluminum alloy lamp, under the current size, th...

AI Technical Summary

Problems solved by technology

Since the existing product is a hand-held aluminum alloy lamp, under the current size, the temperature rise of the product shell will be 40°C, which means that when the ambient temperature is 40°C, the shell will be 80°C, the whole product will be hot, and the inside The temperature of the components will also be relatively high, which cannot guarantee the service life of the product. In addition, the product requires IP67 dustproof and waterproof, so it is impossible to add convection holes. The product must be airtight, so any small size that achieves high power and High-level dustproof and waterproof is the core problem that the existing handheld lighting equipment needs to solve
