The principle description of Embodiment 8-11:

All LED lights have a relatively large heat sink and drive power. To realize a 20-100W independent electric light source, it is obviously impossible to implement the existing LED lighting design. First remove the larger drive power and remove the larger heat sink. The driving power supply can be manufactured according to the method of the Chinese Patent Application No. 201410211945.8 and 201410214074.5, which can reduce the volume of the driving power source into the lamp head of the electric light source, such as the E40 or E27 screw base, which has successfully solved the driving. The problem of placing the power supply.

The remaining problem is how to remove the bulky heat sink is a key point of the present invention. According to the theory of heat dissipation, there are three ways to achieve heat dissipation, 1 heat convection, 2 heat conduction, and 3 heat radiation. The heat sink is the main component of thermal convection, which is the basis of all current LED lighting design. However, it is not enough to realize a replaceable and standardized independent electric light source. The independent electric light source often works in a closed space such as a lamp cover, and the convection heat dissipation which plays a leading role will be invalid.

A person in the window can feel the warm sunshine shining on the body, and the window glass is not hot, this is the radiation of heat rays (visible light waves and infrared light waves); the warm winter sun shines into the vegetable plastic greenhouse to improve the shed The temperature in the shed makes the spring in the shed, and the temperature in the shed is not lost outside the cold shed. This is also the radiation of heat rays. The heat rays of the sunlight can penetrate the greenhouse and the far infrared rays formed by the indoor temperature rise cannot penetrate the greenhouse. The invention introduces the principle of heat ray radiation, namely heat ray, 1 transmission, 2 reflection, 3 absorption. In the design of the electric light source (light bulb), the light is transmitted out of the bulb shell as much as possible, and the energy is emitted out of the bulb; the bulb assembly that is not transparent to the heat ray is designed as a reflecting surface, so that the reflected light is reflected again out of the bulb shell; the heat radiator The component does not reflect or transmit a portion of the heat ray to the black thermally conductive material, thereby enhancing the overall ability of the bulb assembly to externally radiate heat. The ability to radiate heat depends on the area and temperature of the heat radiator (proportional to the 4.2 square of the temperature). It is one of the key steps of the present invention to increase the overall temperature of the bulb assembly relative to the temperature of the LED chip. The light-emitting component should be closely attached to the heat-radiating ring, and the heat-radiating ring should be as close as possible to the bulb shell, and the bulb shell can adopt a tubular structure. The use of a bulb housing to support internal components, particularly high power bulbs, and on the other hand, facilitates the transfer of heat from the heat radiating components to the bulb envelope. The LED electric light source (bulb) is filled with heat-conducting gas, so that the heat on the light-emitting component is quickly and evenly heated by the heat radiation component such as the heat radiation ring, and the temperature of the entire bulb including the bulb shell is rapidly raised to a controllable (design) temperature, as much as possible. The temperature difference between the LED chip on the light-emitting component and the surrounding heat-radiating component is reduced. In order to improve the radiation area, it is best to use a transparent glass shell. The shell has strong ability to transmit visible light waves and infrared light waves, and the glass shell has a relatively large relative area. An important effect of the present invention is that the inner and outer areas of the glass shell are effective for external radiation, and the temperature of the glass shell is improved. At the same time, the radiation capacity of the electric light source (bulb) is greatly increased; another important effect of the invention is that the glass is excellent in insulating material, so that the entire bulb is efficiently insulated, and it is easy to reach various safety standards in the world. The heat radiation ring of the bulb, the heat radiation bracket and the bulb shell constitute all the heat radiation components, which is another key part of the success of the heat radiation design, and its area is closely related to the bulb power. The present invention successfully removes the conventional large volume convection heat sink by the above design.

Still another important effect of the present invention is that directional illumination is achieved on the bulb, ie, a directional electric light source (directional bulb), and a controlled equalization spot can also be achieved by the light distributor 8; furthermore, the improved lamp assembly using the present invention 2 The lamp has high protection performance under the premise of low expenditure, and it is not easy to enter water even if it is placed in water. These are very beneficial to improve the actual lighting efficiency of the bulb, improve the energy-saving effect, expand the scope of the bulb, reduce the complexity of the lamp, and reduce the cost of the lamp.

From another angle, the light-emitting device is mounted inside the bulb, no matter how the light-emitting device is advanced, or the LED or the other, as long as it is a cold light source, the luminous efficiency is not 100%, and the present invention is suitable.
