Multipurpose emergency lamp convenient to fold

Abstract

The invention relates to an emergency lamp convenient to fold. The emergency lamp convenient to fold comprises an emergency lamp body and an external handle, wherein the emergency lamp body comprises a plurality of light emitting units and connecting pieces; each connecting piece is arranged between the two corresponding adjacent light emitting units; each two adjacent light emitting units are connected with each other by the corresponding connecting piece; each light emitting unit is in the shape of a hollow barrel; light emitting devices are arranged in openings in two ends of each light emitting unit; each light emitting device comprises a circuit board, a light source and light emitting glass; the circuit boards are clamped at the openings of the light emitting units; each light source is arranged on the corresponding circuit board; the light emitting glass is hermetically connected with the outlets of the light emitting units; a circuit connecting structure which guarantees that each light emitting unit is connected with the corresponding connecting piece is arranged on the outer side of the emergency lamp body; the external handle can be connected with the emergency lamp body in a clamped manner; and a power source and a button for controlling switching-on and switching-off of the power source are arranged in the handle. By using the emergency lamp, various types of lamplight can be changed; while the structure of the emergency lamp can be lengthened, the circuit can be in a switching-on state; and the emergency lamp is provided with the external power source and is convenient to carry and hang.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a multipurpose emergency light that is easy to fold. Background technique [0002] Folding emergency lights play a very important role in our daily life. Emergency lights are a general term for lamps used for emergency lighting. Emergency lights can be used as emergency lighting for accidents, emergency exit signs and emergency indicators when vehicles are damaged on highways, and emergency lights are essential lighting tools when there is a sudden power outage at home or when traveling in the wild. It is very common in life, but there are many problems in the selection and installation of emergency lights during use. For example, the emergency lights that play a role in marking the emergency exits must be flashing green, the emergency lights must be triangular and red when the vehicle is damaged on high-speed, and in outdoor tents, the emergency lights must have It is easy to...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing emergency lights that are easy to fold have a single light (such as white light, green light, red light, etc.) or flashing light;

[0004] 2. The multiple lamp heads of some emergency lights that are easy to fold are connected in series. When one lamp head is damaged, the entire emergency light will not light up (a defect of a few emergency lights);

[0005] 3. The connection structure between multiple light-emitting units of the existing folding emergency lights mostly adopts the connection structure between the ball head and the ball bowl, and the relative rotation between adjacent light-emitting units is realized by rotating the ball head in the ball bowl , so as to achieve the purpose of folding, and the effect of rotation is also better. However, the light sources in the multiple light emitting units of the existing emergency lights are all connected by wires. In order to ensure that the wires are not exposed, the wires must pass through the light emitting units. The connection structure between the emergency lights will inevitably cause damage to the wires between adjacent light emitting units after a long time during the folding process of the emergency light;

[0006] 4. When the existing foldable emergency lights are extended, although there is no problem in lengthening the structure, in order to ensure that the extended light emitting unit can emit light normally, it is necessary to combine the light source in the new light emitting unit with the light source in the previous light emitting unit. The circuit connection obviously increases the difficulty of operation;

[0007] 5. The power supply of the existing folding emergency lights is built-in and most of them do not have the charging function. After a long time, the battery needs to be replaced, which will cause waste of electric energy and high cost of use;

[0008] 6. The existing folding emergency lights are not easy to hang;
