Description

Cold end direct heat radiation glass heat pipe LED lamp

Technical Field

The invention relates to a glass heat pipe LED lamp with a cold end capable of directly radiating heat. The LED is an english abbreviation of laser light emitting diode, and can be regarded as a recognized technical term in the technical field.

Background

The LED lamp adopting the gravity heat pipe has a general structure that a plurality of LEDs are connected to a hot end below the heat pipe in a heat transfer mode. The main role of the heat pipe in this case is to achieve heat flux density conversion and heat dissipation. The associated heat flux density transitions from approximately 0.5 watts per square centimeter to approximately 0.06 watts per square centimeter.

Considering the existing LED lamp, for one of the LEDs with a length and width of 5 × 7 mm, a total power of 0.6 w, an efficiency of 21%, and energy except for light emission all conducted to the environment through the surface, the total surface area of the LED is 1 cm 2 (0.5 × 0.7 × 2+0.1.25 (7 +5+7+ 5)), and the heat flux density of the heat dissipation load is 0.6 (1-0.21)/1 =0.474 w/cm 2. Without the use of a heat sink, the surface temperature of the LED may exceed 100 ℃.

In addition, for an LED with a heat sink having a heat dissipation load of 10W, the heat dissipation power density was 0.05W/cm 2 in terms of a heat dissipation area 200 parallel square cm on the surface of the heat sink. As a control reference: the peak intensity of the sunlight exposure is about 1 kilowatt per square meter and 0.1 watt per centimeter 2. A25 watt incandescent bulb having a surface area of 170 cm 2 causes a significant temperature rise at the surface of the glass envelope due to the infrared blocking and absorbing effect of the glass envelope. Here, taking 10 watts of heat dissipation power through the glass bulb, the density of the heat dissipation power conducted through the glass bulb is 10/170 ≈ 0.0588 watts/cm 2.

The calculation formula of the object heat dissipation power and the heat dissipation surface temperature rise is as follows:

Q=K*ΔT*S…………

in the formula 1, Q is heat dissipation power, and the dimension is tile; k is the heat transfer coefficient from the surface of the cold end of the glass heat pipe to air, and the dimension is tile/(° c square meter); delta T is the temperature rise of heated air, and the dimension is K or; and S is the area of the cold end of the glass heat pipe in contact with air, and the dimension is square meter.

Substituting Q =10, K =23 watts per square meter (C), and S =0.02 square meter; the temperature rise delta T of the heat dissipation model is obtained to be approximately equal to 21.74 ℃. When S =0.017 square meters, the temperature rise delta T is approximately equal to 25.58 ℃. All heat dissipation loads here enter the environment by heat exchange with the air at an almost average temperature. In practice, the value of the heat transfer coefficient K is also related to the surface conditions, including the cleaning state and the emissivity.

For LED fixtures, the heat dissipation path from the LED to the air is much more complex than for incandescent lamps. The temperature rise value of the surface of the LED lamp radiator relative to the ambient temperature of 30 ℃ is 21.74 ℃, the temperature drop of the heat conducting material between the LED and the hot end of the heat pipe is 2 ℃, the temperature drop of the pipe wall of the hot end of the heat pipe is 2 ℃, the temperature drop of two-phase flow heat exchange from the hot end of the heat pipe to the cold end is negligible, and the temperature drop of the pipe wall of the cold end of the heat pipe is 1 ℃, so that the surface temperature of the LED can reach 30+21.74+1+2+2=56.74 ℃. In view of the fact that the surface temperature of an LED varies with ambient temperature and its own heat flux density. When the highest value of the set environment temperature is 30 ℃, the heat transfer coefficient is set to be 23 and the highest temperature of the LED is 64 ℃, the area of the cold end of the glass heat pipe required by each watt of heat dissipation power is at least 15 square centimeters; the corresponding heat flux density was 0.0667 watts/cm 2. Under the working condition, the light attenuation of the LED10 for ten thousand hours is expected to be lower than 20 percent; and the light attenuation of the few poor LED lamps in the prior art can reach more than 50% only in summer.

Chinese patent 2008200495178 discloses a high-power heat pipe LED lighting device, which includes an LED, a base, a heat pipe, and a heat dissipation device, wherein one side of the base is provided with one or more LEDs, one end, i.e., a hot end, of the heat pipe is connected to the base, and the other end, i.e., a cold end, of the heat pipe is connected to the heat dissipation device. The heat pipe and the base are directly welded or filled with heat-conducting silicone grease without other intermediate heat transfer media, so that the heat resistance is relatively low and the heat transfer efficiency is high. The heat dissipation structure has the characteristics of simple structure, good heat dissipation effect and reliable work. But the base is adopted to be connected with the LED in a heat transfer way, and an electric insulation layer is required to be arranged to realize electric isolation; the cold end of the metal heat pipe is provided with the heat dissipation fin plate as a heat exchange interface with air, and because the temperature between the cold end of the heat pipe and the heat dissipation fin plate is also reduced and the surface temperature of the heat dissipation fin plate is uneven, a heat dissipation link and heat exchange thermal resistance with air are increased; heat sinks are costly and not easily cleaned; an insulating layer with higher pressure resistance is needed between the hot end of the metal heat pipe and the LED, and the insulating layer has thermal resistance. The surface of the LED has much larger temperature drop because of the large heat flow density and the same thermal resistance. Since LEDs are sensitive to temperature, LEDs will decay faster at temperatures above 65 ℃. Therefore, the reduction of the heat transfer link and the reduction of the thermal resistance of the heat transfer link have important significance.

At least two or more of the conductive traces 12 are not directly electrically connected to each other. The inner side surface of the LED circuit board 11 is matched with the outer surface of the hot end of the glass heat pipe 1. The peripheries of the LED circuit board 11 and the driving power base 3 contain a plurality of cable clamping grooves 14. And the quick-connection cables 18 with cable clamping ends 16 at two ends and elastic pieces 17 connected in series in the middle are connected with the LED circuit board 11 and the cable clamping grooves 14 on the driving power supply base 3 in a clamping manner through the cable clamping ends 16, so that the electrical connection between the LED circuit board 11 and the driving power supply base 3, the mechanical connection among the LED circuit board 11, the driving power supply base 3 and the glass heat pipe 1 are realized.

The LED circuit board 11 is also provided with an LED hole 19 for mounting the LED 2.

The LED connection interface 15 made on the LED circuit board 11 is a stainless steel sheet on the circuit board with a thickness of 0.4 mm. The thermal insulation design is adopted between the LED connecting interface 15 and the glass heat pipe 1 so as to reduce thermal shock and heat transfer to the glass heat pipe 1. The contact surface of the LED2 and the glass heat pipe 1 is coated with the heat-conducting binding material 22. The two ends of the LED2 are respectively overlapped with the stainless steel thin plate on the circuit board of the LED connecting interface 15 through the stitch welding flat sheet 24 with the corrugated transition section 23. And (3) stitch welding is carried out on two overlapped stainless steel plates with the thickness of 0.4 mm by adopting laser. The thickness of the stainless steel sheet on the stitch bonding pad 24 and the circuit board of the connection interface 15 can be adjusted. The stainless steel sheet on the LED connection interface 15 board is subjected to laser welding, so the reinforcing layer embedded in the LED circuit board 11 below it should remain a steel sheet.

The reliability of the solder connection may be increased by using a multi-spot stitch such as the 3-spot stitch on the stitch plate 24 depicted in fig. 5.
