Description

LED lamp pearl sterilamp

Technical Field

The utility model relates to an ultraviolet lamp specifically is a LED lamp pearl sterilamp.

Background

The traditional ultraviolet germicidal lamp has the following defects:

1) the volume is large: the traditional ultraviolet lamp is large in size, the diameter of a lamp tube is at least 16mm, the whole thickness of the lamp generally exceeds 25mm due to the size of the lamp holder, the shell and the ballast, and the thickness of a common germicidal lamp is generally 45 mm.

2) Short service life: the service life of the traditional lamp tube is about 5000 hours. And when the lamp works, the front-end ballast is required to invert more than 250V voltage to activate the mercury in the lamp tube and emit ultraviolet light. The DC24V ballast needs the voltage to be rectified from DC24V to ac and then to be boosted to above 250V, and then to start, which has a great impact on the switching life of the lamp tube, and the lamp tube will turn black after the switching life is more than 2000 times, reducing the power output of the lamp tube.

3) Fragile and containing mercury (which is toxic and harmful to humans): the lamp tube is made of glass and is fragile, and the interior of the lamp tube is also provided with low-pressure mercury (the light-emitting principle: ultraviolet germicidal lamp is actually a low-pressure mercury lamp, and the low-pressure mercury lamp is excited by using lower mercury vapor pressure (<10-2Pa) to emit ultraviolet light)

4) The energy source cannot be effectively utilized due to the limitation of the use environment: the power of the lamp tube is 18W, but after the ceiling in the automobile is installed, the actual conversion efficiency is only 60 to 70 percent, namely 10 to 12W, which is also the reason that a plurality of ultraviolet lamp manufacturers add a reflector at the bottom of the lamp, and because a large part of light irradiates the bottom of the lamp, the sterilization effect cannot be effectively converted.

5) Regular maintenance is required: the ultraviolet lamp tube needs to be replaced regularly, and the lamp structure is complex, and the cleaning and maintenance are complex.

The existing LED lamp bead ultraviolet lamp has the following defects:

1) the actual wavelength of the UV lamp of the existing LED lamp bead light source is more than 280nm, the UV lamp basically has no sterilization effect, the sterilization effect can only achieve the purpose of living sterilization with extremely close distance and low surface strength, and the sterilization effect of normal or even medical requirements can not be met.

2) Because LED lamp pearl ultraviolet lamp calorific capacity is big, current lamps and lanterns generally reduce lamps and lanterns power in order to reach the heat dissipation requirement.

3) The existing lamp does not consider extreme use environment, and does not consider environmental adaptability such as high temperature, low temperature, vibration and the like.
