Description

Touch Dimmable Rechargeable LED News Light

technical field

The utility model belongs to the field of news light devices, in particular to a touch-adjustable rechargeable LED news light that can be charged and portable, and can adjust brightness through touch.

Background technique

Current news lamps generally use tungsten-halogen lamps as light sources, which generate a lot of heat and consume a lot of power, and the life of the lamps is short, and the brightness cannot be adjusted. When videography is carried out in some special environments, it is not guaranteed to provide power supply for the lighting of news lights, that is to say, this kind of news lights cannot be used in occasions without power supply. There are also a small number of LED news lights, which adopt the method of separating the body from the battery, but this structure is not easy to carry and operate, and the brightness cannot be adjusted. LED high-brightness light-emitting diodes are low-color-temperature light sources, which can cause color casts in photography and video in many environments.

Utility model content

In order to improve the current defects of the news light, the utility model provides a touch-type dimming and charging portable LED news light, which can perform one-hand touch dimming operation during use.

The technical scheme of the utility model is: touch dimming charging LED news lamp, including a lamp cap and a handle, the lamp cap includes an LED lamp and a shell, and the handle is installed on the shell, and it is characterized in that a charging circuit and a battery pack are arranged in the shell and a touch dimming circuit, the battery pack provides power for the touch dimming circuit, and a touch piece is arranged on the handle for controlling the dimming circuit to adjust the brightness of the LED light source.

A charging power interface is provided on the back of the casing to provide power for the charging circuit.

The touch dimming circuit adopts the touch dimming ICHM9901 integrated circuit.

The touch pad is made of metal material.

The beneficial effects of the utility model are: the touch dimming charging LED news light is composed of a set of charging circuit, a set of battery pack, a set of dimming circuit, a set of LED light source and a touch handle. Charging, when the voltage reaches the requirement, it will automatically stop charging. The power supply of the battery pack passes through the dimming circuit, and the touch piece on the handle controls the touch dimming chip in the news light, and sends out an adjustment signal to drive the tributary solid-state voltage regulator to change the voltage and current supplied to the LED light source to achieve dimming. The purpose of brightness while changing its color temperature.

In actual use, the battery and the body can be integrated, and the built-in charging circuit and dimming circuit can realize the actions of one-handed light and touch dimming. The most important thing is that the brightness of the LED light source can be adjusted while changing its color temperature.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Detailed ways

In Fig. 1, the touch dimming rechargeable LED news light includes a lamp cap 1 and a handle 2, the lamp cap 1 includes an LED lamp 3 and a housing 4, the handle 2 is installed on the housing 3, and a charging circuit, A battery pack and a touch dimming circuit, the battery pack provides power for the touch dimming circuit. A touch piece 5 is provided on the handle 2. The touch piece 5 is made of metal material and is used to control the dimming circuit to adjust the brightness of the LED light source. A charging power interface 6 is provided on the back of the housing 3 to provide power for the charging circuit. 7 is the LED news light switch (see Figure 2). The touch dimming circuit adopts the touch dimming ICHM9901 integrated circuit.

Figure 3 is an intelligent charging circuit. After the input terminal of the power supply passes through the filter circuit of R7 and C2, it is input to the input terminal of AN051A through a voltage regulator tube. The output terminal of AN051A is used to charge the battery pack. The indicator light is connected to the battery pack through VT1S19405D and R6. When the charging of the battery pack reaches the rated voltage, stop charging, turn off the power supply, and the LED indicator light is on to indicate that it is fully charged.

Figure 4 is the touch dimming control circuit. The integrated circuit adopts touch dimming and integrates ICHM9901. The incoming human body induction signal controls the 8-pin output modulation signal of HM9901, and drives the DC solid-state voltage regulator to change the power supply voltage supplied to the LED bright light-emitting diode group to achieve the purpose of dimming.
