Description

LED energy saving lamp for door frame type lamp

Technical field

The utility model relates to the field of energy-saving lamps, in particular to an LED energy-saving lamp of a door-frame type lamp tube.

Background technique

Electric lights have been in people's lives for more than 100 years, from the initial heating of the resistance wire to the incandescent lamp in the incandescent state, to the current halogen lamp, fluorescent lamp, ceramic metal lamp, LED lamp and other forms. The traditional energy-saving lamp is a kind of lamp that combines a fluorescent lamp and a ballast into a whole. The size is similar to that of an incandescent lamp, and the interface with the lamp holder is the same as that of an incandescent lamp. Under the premise of light output, the power consumption is only ordinary. 1/5 to 1/4 of incandescent lamps replace incandescent lamps in everyday lighting. However, the fluorescent lamp that constitutes the energy-saving lamp uses mercury vapor to radiate ultraviolet rays during the discharge process, so that the phosphor emits visible light. Therefore, the energy-saving lamp must be filled with mercury. Once the lamp is broken, it will cause serious pollution to the environment, and the mercury exceeds the standard. It can also cause serious harm to the human body and even death. LED energy-saving lamps that use LEDs instead of mercury to generate ultraviolet light to emit visible light into the light have entered people's lives. However, such lamps must be equipped with a heat dissipating mechanism to dissipate the heat generated by the LED chips during operation to avoid excessive temperature and lower LEDs. The efficacy and longevity of the chip. At present, the lamps of the LED energy-saving lamps are mostly U-shaped or H-shaped, and the substrate on which the LED chips are mounted cannot be inserted into the curved portion of the U-shaped tube, and the H-shaped tube can be inserted into the bottom, but the horizontal portion communicates with the vertical portion. In the middle, both ends are blocked by the substrate, and the light reflected to the horizontal part is very small. When the two lamps are viewed from the top, the light at the center is obviously dark, and the illumination effect is not ideal.

Summary of the invention

The technical problem to be solved by the utility model is to provide an LED energy-saving lamp with a door-frame type lamp tube, which can solve the problem that the existing LED energy-saving lamp adopts a U-shaped or H-shaped lamp tube, and the light at the center of the top end is dark, resulting in unsatisfactory lighting effect. problem.

The utility model is realized by the following technical solutions:

An LED energy-saving lamp for a door-frame type lamp, comprising a lamp holder, and a lamp cap and a lamp tube mounted on the lamp holder, wherein the lamp holder wall is provided with a venting hole communicating with the inner cavity thereof, wherein the lamp holder inner cavity is provided The LED power module has an LED input terminal connected to the lamp cap. The lamp tube is composed of two vertical portions and a horizontal portion. One ends of the two vertical portions respectively communicate with the lamp holder, and the other ends are respectively connected to the horizontal level. a heat dissipation hole is disposed on one side of the horizontal portion facing the lamp holder, and a substrate is respectively disposed in two vertical portions of the lamp tube, the back surface of the substrate is attached to the pipe wall, and the LED chip is mounted on the front surface. The LED chip is connected to an output end of the LED power module.

According to a further improvement of the present invention, the back surface of the substrate is bonded to the U-shaped tube by glue.

According to still another improvement of the present invention, the substrate is a PCB board, and the LED chip is soldered on the PCB board.

According to still another improvement of the present invention, the lamp tube is made of glass, and the inner wall thereof is provided with a diffusion powder layer.

According to still another improvement of the present invention, the LED chip is a phosphor converted LED.

The advantages of the utility model compared with the prior art are:

1. A door-frame type lamp composed of two vertical sections and a horizontal section, the substrate on which the LED chip is mounted can be inserted to a sufficient depth, and the illumination angle of the LED chip is 120°, and the light emitted by the LED chip on the upper part of the substrate is reflected through the pipe wall. Entering the horizontal part will not be blocked, improve the brightness at the center of the top end of the lamp, and improve the lighting effect;

2. The lamp tube communicates with the inner cavity of the lamp holder, and a heat dissipation hole is arranged horizontally at the lamp tube to match the vent hole on the lamp holder, and an air passage connecting the two ends to the outside is formed on the lamp, and the air in the lamp has good air. Circulating, the heat generated by the LED chip can be distributed to the outside of the lamp through the air circulation in time, to avoid the heat accumulation affecting the light efficiency and service life of the LED chip; the heat dissipation hole is arranged on the side of the lamp tube facing the lamp holder to prevent water, ash, etc. Contaminants entering the lamp tube can also prevent the direct light emitted by the LED chip from causing discomfort to the human eye;

Third, the back side of the PCB board is attached to the vertical part of the lamp tube, and the heat conducted by the LED chip to the PCB board can be dissipated through the wall of the lamp tube, and the air flow contacted by the light emitting surface of the LED chip can be maximized, and the lamp can be further reduced. The temperature inside the tube;

Fourth, the back side of the PCB board is glued to the lamp tube, which can prevent the gap between the PCB board and the lamp tube wall from being loose, affecting the heat transfer effect, or causing damage to the lamp tube or de-soldering of the LED chip on the PCB board;

5. The transparency of the glass is good. The diffusing powder layer is arranged on the inner wall of the glass tube, which can convert the visible light emitted by the LED into more and more uniform light, and improve the overall brightness of the lamp.
