Description

LED lamps and bulbs with heat dissipation and waterproof gas

The invention relates to an LED lamp and a bulb, in particular to an LED bulb with heat dissipation and waterproof gas.

The heat dissipation structure of the LED bulb can reduce the maximum cause of light decay. Therefore, the manufacturer has to design various heat conduction and heat dissipation structures, and hopes to solve the heat dissipation problem of the LED bulb.

Although the conventional LED bulbs 1A, 1B, 1C, 1D, and 1E shown in FIG. 1 to FIG. 5 are separately provided with the venting port 11 and/or the convection port 12 for external heat dissipation to the periphery of the heat dissipating member 13, the following defects are still present. :

1. Since there is no air convection in the bulb inner cavity 14, it is impossible to suck in the cold air by the rise of the hot air to generate a circulating heat dissipation effect, which causes heat generation in the inner cavity wall.

2. The heat generated by the LED 15 is transferred to the substrate 16 and is dissipated by the outer end surface of the substrate 16. However, since the cavity 171 of the light-transmitting shell 17 is sealed, the heat of the outer end surface of the substrate 16 can only travel inside the cavity 171, and cannot escape and accumulate heat. The accumulation of heat in the cavity 171 aggravates the risk of the LED 15 being subjected to temperature rise, resulting in an increase in light decay.

3. Some of the conventional LED bulbs have an air passage 18 communicating with the inner chamber 14 to provide a heat dissipation function. However, when the LED bulb is not actuated, cold air may invade the inner chamber 14 through the vent 11. When the moisture in the air is heavier, the moisture that invades the inner cavity 14 will Gradually oxidize the metal guides and solder joints outside the driver electronics inside the bulb/lamp to reduce the life of the driver. This is also the reason why the high-end LED bulb (shown as 1F in Fig. 6) is still rarely used as a heat dissipation structure.

In order to make LED bulbs compatible with traditional lamp-up fixtures, such as vertical lamps (see Figure 7), desk lamps (see Figure 8), wall lamps 7 (see Figure 9) or landscape lights (see Figure 10), many companies will The overall length of the LED bulb (see L1 in Figure 11) is shortened, the length of the light-transmissive shell (L2 in Figure 11) is lengthened, the length of the heat sink (L3 in Figure 11) is shortened, and the light source of the LED 15 is placed high in the light-transmitting shell. Above the bottom edge 19 (see Figure 11). This design has two purposes for the lamp head up fixture:

1. The shortening of the length of the bulb allows the direct light (see B1 in Fig. 12) to be directly incident on the light-transmissive shell or the reflector to increase the area, so that the area of the reflected light (see B2 in Fig. 12) is increased.

2. As shown in FIG. 13 , the LED 15 light source is placed on the bottom edge 19 of the light-transmissive shell to increase the reflection of the left and right oblique rays formed by the reflection of the light source on the inner edge of the light-transmitting shell, so that the visual sense is transparent. The light transmission angle of the shell is increased.

However, the high light source causes the base of the light source substrate to protrude from the cavity 171. When the LED is actuated, the temperature experienced in the cavity 171 will be superimposed with the surface area of the protruding pedestal, so that the temperature of the LED is increased, and the risk of increased light decay is increased. According to the experimental data, the design of the high light source and the shrinkage of the external heat dissipating surface will increase the temperature of the heat sink by about 12-15 degrees or more, resulting in a new material that requires heat conduction and heat dissipation as the lamp body structure. But this will increase the cost, which is a major obstacle to the popularity of LED bulbs.

FIG. 14 shows another conventional LED lamp 2, wherein the lamp holder 2 has a plurality of venting ports 22 at the upper end thereof, and the venting port 22 is covered with a waterproof and permeable cloth 23 so that moisture does not enter the luminaire 2 from top to bottom. (Water vapor is heavier than air and will sink from top to bottom). However, the chamber 24 of the lamp body is hermetic, and the heat generated by the LED light source cannot escape. thus, Although the LED lamp 2 has an upward venting vent 22, because there is no intake air to circulate, the chimney effect cannot be formed, and the LED will withstand the temperature rise, resulting in an increase in light decay.

Therefore, how to design LED bulbs/lamps to have the effect of heat dissipation and waterproof gas is really an urgent task for LED manufacturers.

In a preferred embodiment, the present invention provides an LED bulb with heat dissipation and waterproof gas. The LED bulb comprises a base, a socket, a light-transmissive shell, a heat sink and a light-emitting module. The base comprises a head end mounted with a base and an open end.

The inner cavity of the heat dissipating body and the venting perforation of the substrate can form a chimney effect with the first and second venting ports, so that the hot air inside and outside of the heat dissipating body can dissipate heat from the exhaust and the intake air.
