Description

an emergency light

technical field

The utility model belongs to a lighting device, in particular to an emergency light.

Background technique

In the prior art, there are many kinds of light sources used in traditional emergency lights for lighting, which are generally classified into incandescent lamps, tungsten halogen lamps, fluorescent tubes, halogen lamps, gas discharge lamps, etc. according to different purposes. But above various light fixtures also have such or such shortcoming while having some unique advantages respectively. For example, incandescent lamps have low luminous efficiency; due to the working principle of tungsten-halogen lamps, the temperature of the inner wall of the bulb must be kept above 250°C, which makes the lamps hot and easy to burn; fluorescent tubes contain mercury and ultraviolet light, which has a certain degree of damage to the environment , and requires high-voltage drive, which is likely to cause safety problems; both halogen lamps and gas discharge lamps contain ultraviolet light, which is harmful to the human body, and also require high-voltage drive. etc. In addition, a common disadvantage of the above-mentioned various lamps is that their lifespan is relatively short, and all of them are made of glass shells, which are easily affected by vibration, fragile, and prone to danger.

Utility model content

The purpose of the utility model is to provide an emergency light, which adopts a light-emitting diode as a light source, and has the advantages of energy saving, high light efficiency, safety, long service life and soft light.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an emergency light, including a light source, a lamp holder and an emergency conversion circuit, the light source is composed of a light emitting diode module, a reflector and a transparent cover, and the light emitting diode module buckle on the reflector.

More preferably, the light-emitting diode module is surrounded by a frame, including a circuit board layer and a light-emitting diode chip, the light-emitting diode chip is installed on the circuit board layer, a phosphor layer is filled between the light-emitting diode chip and the circuit board layer, and the phosphor layer Sealed with silica gel.

More preferably, the emergency conversion circuit includes a DC storage battery, and the DC storage battery is connected between the charging and discharging detection circuit and the AC-DC switching detector.

And, the reflective plate and the transparent cover are buckled together, and the reflective plate is provided with a groove matching the LED module.

Because the utility model applies the light-emitting diode module to the emergency light, and adopts the light-emitting diode as the light source, there is no flicker, no ultraviolet and infrared radiation, so the light is soft and the light efficiency is high; because the light-emitting diode module adopts high-quality light-emitting diode Chip, this emergency light has low power and saves more electricity. At the same time, the capacity of the battery can be greatly reduced during emergency use, and the service life is long.

Detailed ways

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

As shown in Figures 1 and 2, the utility model discloses an emergency light, which includes a light source 1, a lamp holder 2, and an emergency conversion circuit 3. The light source 1 is composed of a light-emitting diode module 11, a reflector 12, and a transparent cover 13. The diode module 11 is buckled in the groove 14 on the reflector 12 that matches the shape and size of the light emitting diode module 11, the reflector 12 and the transparent cover 13 are buckled together, the light emitted by the light emitting diode module 11 is reflected by the reflector 12, It is concentratedly reflected by the transparent cover 13.

Wherein, the LED module 11 is surrounded by a frame 111, as shown in FIG. 3 , including a circuit board layer 112 and an LED chip 113. The phosphor layer 114 is filled, and the phosphor layer 114 is sealed by silica gel 115 . The uniform filling of the fluorescent powder improves the luminous efficiency of the diode, and the color temperature is uniform, the light is uniform and soft, and the manufacturing process is simple and the production cost is low.

As shown in FIG. 4 , the emergency conversion circuit 3 includes a DC storage battery 31 , and the DC storage battery 31 is connected between the charging and discharging detection circuit 32 and the AC-DC switching detector 33 . What the emergency light wants to achieve is that when there is mains power input, the LED module 11 is powered by the rectified and filtered AC power, and at the same time charges the included DC battery 31. The battery input terminal is connected with a charge and discharge detection circuit 32 to Realize the charging control of the storage battery. When there is no commercial power supply, the AC-DC switching circuit 33 connected to the output terminal of the DC battery 31 will work, and the battery is used as the emergency power supply for the LED module 11 .

Because the utility model applies the light-emitting diode module 11 to the emergency light, and adopts the light-emitting diode as the light source, there is no flicker, no ultraviolet and infrared radiation, so the light is soft and the light efficiency is high; because the light-emitting diode module 11 adopts high-quality The light-emitting diode chip 113, the power of the emergency light is small, more power-saving, and at the same time, the capacity of the battery can be greatly reduced during emergency use, and the service life is long.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
