Abstract

The utility model discloses a double-lamp type LED energy-saving flashlight, which is characterized in that two LED light-emitting diodes which can be switched on are arranged in one flashlight at the same time. It can be installed with two light-emitting diodes with low-power soft light or two LED light-emitting diodes with high-power strong light at the same time, or one light-emitting diode with low-power soft light and the other light-emitting diode with high-power strong light. It overcomes the trouble of changing light bulbs. When students rush to do their homework in the event of a power outage, the use of soft light can not only protect eyesight but also save energy consumption.

Description

A double lamp type LED energy-saving flashlight

technical field

The utility model relates to a double-lamp type LED energy-saving flashlight, which adopts an energy-saving LED lamp tube (light-emitting diode) to replace the common bulb-type flashlight that consumes a lot of electricity, and uses a double-lamp flat flashlight to replace the traditional round single lamp flashlight.

Background technique

The traditional one-, two-, three-, and five-cell flashlights are often faced with high voltage when the new battery is replaced. Although the light is strong and bright, it is very easy to explode the bulb (the filament is blown out) and in case of a power outage, it is urgent to read books and do homework. Eyesight damage; the voltage of the used battery is just right, but the time is not long, and the degradation is accelerated; the voltage of the old battery is too low, and the dimming effect of the light is poor. If there is an urgent need for lighting, replace the battery or replace the battery with a new battery. It's all trouble. Because the use of LED lamps (light-emitting diodes) can be added with an automatic boosting or voltage stabilizing system, it is now gradually replacing the relatively power-hungry LED (light-emitting diode) torches with less power consumption and automatic boosting or voltage stabilizing components. Ordinary bulb-style traditional flashlights, but the biggest disadvantage is that the light-emitting diodes are welded on the internal circuit board. If the light-emitting diodes are damaged, it is difficult for users to replace them by themselves. It is much more difficult than replacing ordinary lights, so it is used by some users. Nicknamed "disposable flashlight".

Contents of the invention

In order to overcome the defect that the single lamp tube is damaged and can no longer be used normally, the purpose of this utility model is to provide a technical solution for a double-lamp LED energy-saving flashlight, changing the original one-way switch into a two-way switch or adding a two-way switch The switch adopts dual output and double lamps, which are divided into: A lamp and B lamp. Usually, you only need to flick the two-way switch to switch to use. The lamp tubes A and B can be equipped with lamp tubes of the same power, or a low-power soft light lamp tube can be installed for primary school students to do homework in a power outage, and the other can be installed with a high-power strong light tube.

The beneficial effect of the utility model is: when the user urgently needs to use the flashlight, it is generally used in an emergency power failure, or when the light is urgently needed in the dark. B light tube, it will not delay the precious time of users in emergency. If A and B lamp tubes of considerable power are installed during normal lighting, the service time of A and B lamp tubes should be changed frequently, which can also reduce the heating and aging of the lamp tubes, thereby prolonging the service life of the lamp tubes. If the A and B light tubes of large and small powers are installed separately, you can choose between soft light or strong light according to actual needs, so as to make the best use of everything, save battery consumption and the precious time for changing light tubes to the greatest extent.

Detailed ways

Describe below in conjunction with embodiment and accompanying drawing thereof:

Referring to accompanying drawing 1, this is a kind of left and right double lamp type LED energy-saving flashlight of the present utility model in parallel, by shell (1), battery (2) automatic voltage regulation circuit board (3), low-power soft light lamp tube (A), high-power strong light tube (B) two-way toggle switch (K), etc., when using a flashlight for lighting, the two-way switch can be toggled to select low-power soft light or high-power strong light according to actual needs. If the lamp tube (A) is damaged, the lamp tube (B) can be lighted only by flipping the two-way switch. If the lamp tubes A and B of equal power are installed, the two-way switch should be toggled frequently when the flashlight is used for lighting at ordinary times so that the lamp tube (A) and the lamp tube (B) can be used alternately to prolong the service life of the lamp tube.

Referring to accompanying drawing 2, this is a kind of left and right side-by-side double-lamp type LED energy-saving flashlight of the present utility model, and B-2 is a detachable high-brightness long-distance LED light-emitting diode spotlight head, when lamp head (B-2) Turns into a high-brightness, long-range torch when the flashlight is plugged in. If the lamp head (B-2) is disassembled from the flashlight, the flashlight becomes lighter and can be put into any pocket of any clothes. It can become a must-have for the elderly and primary school students walking at night, going up and down stairs.

Referring to accompanying drawing 3, this is a kind of double-lamp type LED energy-saving flashlight arranged front and rear of the present utility model, and its operating principle is identical with accompanying drawing 1.

Referring to accompanying drawing 4, this is a kind of front and back arrangement double-lamp type LED energy-saving flashlight of the present utility model, and its working principle is the same as accompanying drawing 2, and the lamp holder (B-2) is a detachable high-brightness long-distance LED spotlight head.
